SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, or Quarterly Report, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements may be identified by the fact that they do not relate strictly to historical or current facts. You may identify forward-looking statements in this Quarterly Report by the use of words such as “anticipates,” “estimates,” “expects,” “intends,” “plans”, “seeks” and “believes,” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could.” These forward-looking statements include, among others, all statements relating to our future financial performance, our business prospects and strategy, anticipated financial position and financial strength ratings, liquidity and capital needs and other similar matters. These forward-looking statements are based on management’s current expectations and assumptions about future events, which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict.

Our actual results may differ materially from those expressed in, or implied by, the forward-looking statements included in this Quarterly Report as a result of various factors, many of which are beyond our control, including, among others:

•the inherent uncertainty of estimating reserves and the possibility that incurred losses may be greater than our loss and loss adjustment expense reserves;

•inaccurate estimates and judgments in our risk management may expose us to greater risks than intended;

•downgrades in the financial strength rating of our regulated insurance subsidiaries impacting our ability to attract and retain insurance and reinsurance business that our subsidiaries write, our competitive position, and our financial condition;

•the potential loss of key members of our management team or key employees, and our ability to attract and retain personnel;

•adverse economic factors resulting in the sale of fewer policies than expected or an increase in the frequency or severity of claims, or both;

•the impact of a persistent high inflationary environment on our reserves, the values of our investments and investment returns, and our compensation expenses;

•exposure to credit risk, interest rate risk and other market risk in our investment portfolio;

•reliance on a select group of brokers and agents for a significant portion of our business and the impact of our potential failure to maintain such relationships;

•reliance on a select group of customers for a significant portion of our business and the impact of our potential failure to maintain, or decision to terminate, such relationships;

•our ability to obtain reinsurance coverage at prices and on terms that allow us to transfer risk and adequately protect our Company against financial loss;

•losses resulting from reinsurance counterparties failing to pay us on reinsurance claims, insurance companies with whom we have a fronting arrangement failing to pay us for claims, or a former customer with whom we have an indemnification arrangement failing to perform its reimbursement obligations, and our potential inability to demand or maintain adequate collateral to mitigate such risks;

•inadequacy of premiums we charge to compensate us for our losses incurred;

•changes in laws or government regulation, including tax or insurance law and regulations;

•the ongoing effect of Public Law No. 115-97, informally titled the Tax Cuts and Jobs Act, which may have a significant effect on us including, among other things, by potentially increasing our tax rate, as well as on our shareholders;

•in the event we do not qualify for the insurance company exception to the passive foreign investment company (“PFIC”) rules and are therefore considered a PFIC, there could be material adverse tax consequences to an investor that is subject to U.S. federal income taxation;

•the Company or any of its foreign subsidiaries becoming subject to U.S. federal income taxation;

•a failure of any of the loss limitations or exclusions we utilize to shield us from unanticipated financial losses or legal exposures, or other liabilities;

3

•losses from catastrophic events, such as natural disasters and terrorist acts, which substantially exceed our expectations and/or exceed the amount of reinsurance we have purchased to protect us from such events;

•the effects of the COVID-19 pandemic and associated government actions on our operations and financial  performance;

•potential effects on our business of emerging claim and coverage issues;

•the potential impact of internal or external fraud, operational errors, systems malfunctions or cyber security incidents;

•our ability to manage our growth effectively;

•failure to maintain effective internal controls in accordance with Sarbanes-Oxley Act of 2002, as amended (“Sarbanes-Oxley”);

•changes in our financial condition, regulations or other factors that may restrict our subsidiaries’ ability to pay us dividends; and

•other risks and uncertainties discussed elsewhere in this Quarterly Report.

Additional information about these risks and uncertainties, as well as others that may cause actual results to differ materially from those in the forward-looking statements, is contained in our filings with the U.S. Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 1, 2022.

Forward-looking statements speak only as of the date of this Quarterly Report. Except as expressly required under federal securities laws and the rules and regulations of the SEC, we do not have any obligation, and do not undertake, to update any forward-looking statements to reflect events or circumstances arising after the date of this Quarterly Report, whether as a result of new information or future events or otherwise. You should not place undue reliance on the forward-looking statements included in this Quarterly Report or that may be made elsewhere from time to time by us, or on our behalf. All forward-looking statements attributable to us are expressly qualified by these cautionary statements.

The Company owns five insurance companies based in the United States (“U.S.”) focused on specialty insurance niches and two Bermuda-based reinsurance companies as described below:

•James River Group Holdings UK Limited (“James River UK”) is an insurance holding company formed in 2015 in the United Kingdom (“U.K.”). JRG Holdings contributed James River Group, Inc. (“James River Group”), a U.S. insurance holding company, to James River UK in 2015.

•James River Group is a Delaware domiciled insurance holding company formed in 2002 which owns all of the Company’s U.S.-based subsidiaries, either directly or indirectly through one of its wholly-owned U.S. subsidiaries. James River Group oversees the Company’s U.S. insurance operations and maintains all of the outstanding debt in the U.S.

•James River Insurance Company is an Ohio domiciled excess and surplus lines insurance company that, with its wholly-owned insurance subsidiary, James River Casualty Company, a Virginia domiciled company, is authorized to write business in every state and the District of Columbia.

•Falls Lake National Insurance Company (“Falls Lake National”) is an Ohio domiciled insurance company which wholly owns Stonewood Insurance Company (“Stonewood Insurance”), a North Carolina domiciled company, and Falls Lake Fire and Casualty Company, a California domiciled company.

Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 for a more complete description of the Company’s business and accounting policies. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results of operations for the full year. The consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited annual consolidated financial statements.

Intercompany transactions and balances have been eliminated.

Estimates and Assumptions

Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.

Variable Interest Entities

Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to an entity on an ongoing basis.

The Company holds interests in VIEs through certain equity method investments included in “other invested assets” in the accompanying condensed consolidated balance sheets. The Company has determined that it should not consolidate any of the VIEs as it is not the primary beneficiary in any of the relationships. Although the investments resulted in the Company holding variable interests in the entities, they did not empower the Company to direct the activities that most significantly impact the economic performance of the entities. The Company’s investments related to these VIEs totaled $28.2 million and $26.9 million at September 30, 2022 and December 31, 2021, respectively, representing the Company’s maximum exposure to loss.

Income Tax Expense

Our effective tax rate fluctuates from period to period based on the relative mix of income reported by country and the respective tax rates imposed by each tax jurisdiction. For U.S.-sourced income, the Company’s U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate to income before taxes due primarily to interest income on tax-advantaged state and municipal securities, dividends received income, and excess tax benefits on share based compensation. For the nine months ended September 30, 2022, our U.S. federal income tax expense was 30.9% of the income before taxes. The effective rate exceeded the 21.0% U.S. statutory rate due to a projected annual loss in Bermuda that does not provide a tax benefit and certain discreet items including excess tax expenses associated with vested restricted share units (“RSUs”) in the nine months ended September 30, 2022. The Company had a pre-tax loss of $129.6 million for the nine months ended September 30, 2021 and recorded a U.S. federal income tax benefit of $23.1 million. For the nine months ended September 30, 2021, our U.S. federal income tax benefit was 17.8% of the loss before taxes. The pre-tax loss was largely driven by the $210.8 million of net adverse reserve development on prior accident years, including $190.7 million of net adverse development from the Excess and Surplus Lines segment that was primarily related to a former commercial auto account.

Adopted Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 simplifies the accounting for convertible debt instruments and convertible preferred stock and became effective for interim and annual periods beginning after December 15, 2021. The Company adopted the new standard concurrent with the issuance of our Series A preferred shares on March 1, 2022. Under ASU 2020-06, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. The new guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and generally requires them to include the effect of potential share settlement for instruments that may be settled in cash or shares. Adoption of the new standard did not materially impact our financial position, results of operations, or earnings per share for the nine months ended September 30, 2022.

At September 30, 2022, the Company held fixed maturity securities of 573 issuers that were in an unrealized loss position with a total fair value of $1,613.5 million and gross unrealized losses of $200.7 million. None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduled principal or interest payment. At September 30, 2022, 99.8% of the Company’s fixed maturity security portfolio was rated “BBB-” or better (“investment grade”) by Standard & Poor’s or received an equivalent rating from another nationally recognized rating agency. Fixed maturity securities with ratings below investment grade by Standard & Poor’s or another nationally recognized rating agency at September 30, 2022 had an aggregate fair value of $2.6 million and an aggregate net unrealized loss of $250,000.

The Company reviews its available-for-sale fixed maturities to determine whether unrealized losses are due to credit-related factors. An allowance for credit losses is established for any credit-related impairments, limited to the amount by which fair value is below amortized cost. Changes in the allowance for credit losses are recognized in earnings and included in net realized and unrealized gains (losses) on investments. Unrealized losses that are not credit-related are recognized in other comprehensive income.

The Company considers the extent to which fair value is below amortized cost in determining whether a credit-related loss exists. The Company also considers the credit quality rating of the security, with a special emphasis on securities downgraded below investment grade. A comparison is made between the present value of expected future cash flows for a security and its amortized cost. If the present value of future expected cash flows is less than amortized cost, a credit loss is presumed to exist and an allowance for credit losses is established. Management may conclude that a qualitative analysis is sufficient to support its conclusion that the present value of the expected cash flows equals or exceeds a security’s amortized cost. As a result of this review, management concluded that there were no credit-related impairments of fixed maturity securities at September 30, 2022, December 31, 2021, or September 30, 2021. Management does not intend to sell the securities in an unrealized loss position, and it is not “more likely than not” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs.

Bank loan participations are measured at fair value pursuant to the Company's election of the fair value option, and changes in unrealized gains and losses in bank loan participations are reported in our income statement as net realized and unrealized gains (losses) on investments. Applying the fair value option to the bank loan portfolio increases volatility in the Company's financial statements, but management believes it is less subjective and less burdensome to implement and maintain than the requirements of ASU 2016-13. At September 30, 2022, the Company's bank loan portfolio had an aggregate fair value of $160.3 million and unpaid principal of $178.8 million. Investment income on bank loan participations included in net investment income was $3.4 million and $8.4 million for the three and nine months ended September 30, 2022, respectively ($2.8 million and $8.2 million for the three and nine months ended September 30, 2021, respectively). Net realized and unrealized gains (losses) on investments includes losses on bank loan participations of $2.2 million and $14.2 million for the three and nine months ended September 30, 2022, respectively (gains of $195,000 and $6.0 million for the three and nine months ended September 30, 2021, respectively). For the three and nine months ended September 30, 2022 and 2021, management concluded that none of the unrealized losses were due to credit-related impairments. Losses due to credit-related impairments are determined based upon consultations and advice from the Company's specialized investment manager and consideration of any adverse situations that could affect the borrower's ability to repay, the estimated value of underlying collateral, and other relevant factors.

Bank loan participations generally provide a higher yield than our portfolio of fixed maturities and have a credit rating that is below investment grade (i.e. below “BBB-” for Standard & Poor’s) at the date of purchase. These bank loans are primarily senior, secured floating-rate debt rated “BB”, “B”, or “CCC” by Standard & Poor’s or an equivalent rating from another nationally recognized rating agency. These bank loans include assignments of, and participations in, performing and non-performing senior corporate debt generally acquired through primary bank syndications and in secondary markets. Bank loans consist of, but are not limited to, term loans, the funded and unfunded portions of revolving credit loans, and other similar loans and investments. Management believed that it was probable at the time that these loans were acquired that the Company would be able to collect all contractually required payments receivable.

Interest income on bank loan participations is accrued on the unpaid principal balance, and discounts and premiums on bank loan participations are amortized to income using the interest method. Generally, the accrual of interest on a bank loan participation is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest. A bank loan participation may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Generally, bank loan participations are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Interest received on nonaccrual loans generally is reported as investment income. There were no bank loans on nonaccrual status at September 30, 2022 or December 31, 2021.

(a)The Company's Excess and Surplus Lines and Corporate and Other segments own equity interests ranging from 2.6% to 32.6% in various LLCs whose principal objective is capital appreciation and income generation from owning and operating renewable energy production facilities (wind and solar). The LLCs are managed by an entity for which two former directors served as officers, and the Company’s Non-Executive Chairman has invested in certain of these LLCs. The equity method is used to account for the Company’s LLC investments. Income for the LLCs primarily reflects adjustments to the carrying values of investments in renewable energy projects to their determined fair values. The fair value adjustments are included in revenues for the LLCs. Expenses for the LLCs are not significant and are comprised of administrative and interest expenses. The Company received cash distributions from these investments totaling $1.4 million and $1.8 million in the nine months ended September 30, 2022 and 2021, respectively.

(b)The Company's Excess and Surplus Lines and Corporate and Other segments have invested in notes receivable for renewable energy projects. At September 30, 2022, the Company held two notes issued by an entity for which two of our former directors serve as officers. Interest on the notes, which mature in 2025, is fixed at 12%.

(c)The Company owns investments in limited partnerships that invest in concentrated portfolios including publicly-traded small cap equities, loans of middle market private equity sponsored companies, private equity general partnership interests, commercial mortgage-backed securities, and tranches of distressed home loans. Income from the partnerships is recognized under the equity method of accounting. During the three and nine months ended September 30, 2022, the Company recognized an impairment loss of $392,000 on one limited partnership in the Corporate & Other segment. At September 30, 2022, the Company’s Excess and Surplus Lines segment has outstanding commitments to invest another $5.3 million in the other limited partnerships.

(d)The Company's Excess and Surplus Lines segment holds $4.5 million of subordinated notes issued by a bank holding company for which the Company’s Non-Executive Chairman was previously the Lead Independent Director and an investor

The Company experienced $1.1 million of net favorable reserve development in the three months ended September 30, 2022 on the reserve for losses and loss adjustment expenses held at December 31, 2021 (excluding adverse prior year development on the legacy commercial auto business subject to retroactive reinsurance accounting - see Commercial Auto Loss Portfolio Transfer below). This reserve development included $139,000 of net adverse development in the Excess and Surplus Lines segment, $1.3 million of net favorable development in the Specialty Admitted Insurance segment, and no development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the three months ended September 30, 2022 related to Hurricane Ian. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

The Company experienced $44.1 million of net adverse reserve development in the three months ended September 30, 2021 on the reserve for losses and loss adjustment expenses held at December 31, 2020. This reserve development included $29.5 million of net adverse development in the Excess and Surplus Lines segment (see Commercial Auto Loss Portfolio Transfer below), $500,000 of net favorable development in the Specialty Admitted Insurance segment, and $15.1 million of net adverse development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the three months ended September 30, 2021 related to Hurricane Ida. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

Notes to Condensed Consolidated Financial Statements (continued)

The Company experienced $4.1 million of net adverse reserve development in the nine months ended September 30, 2022 on the reserve for losses and loss adjustment expenses held at December 31, 2021 (excluding adverse prior year development on the legacy commercial auto business subject to retroactive reinsurance accounting - see Commercial Auto Loss Portfolio Transfer below). This reserve development included $48,000 of net adverse development in the Excess and Surplus Lines segment, $2.8 million of net favorable development in the Specialty Admitted Insurance segment, and $6.8 million of net adverse development in the Casualty Reinsurance segment that was associated with the Retrocession Agreement (as defined below). The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the nine months ended September 30, 2022 related to Hurricane Ian. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

The Company experienced $210.8 million of net adverse reserve development in the nine months ended September 30, 2021 on the reserve for losses and loss adjustment expenses held at December 31, 2020. This reserve development included $190.7 million of net adverse development in the Excess and Surplus Lines segment including $200.1 million on commercial auto business almost entirely related to a previously canceled account that has been in runoff since 2019. The reported losses on this terminated commercial auto account meaningfully exceeded our expectations for the three months ended March 31, 2021. We had expected that reported losses would decline as the account moved further into runoff, but the continued heavy reported loss emergence in the first quarter of 2021 indicated more inherent severity than anticipated. The continuation of the highly elevated reported losses in the first quarter of 2021 led us to conclude that using only our own loss experience in our paid and incurred reserve projections rather than industry data inputs that we had used in prior quarters, and giving greater weight to incurred methods, would give us a better estimate of ultimate losses on this account. In response, we meaningfully adjusted our actuarial methodology, resulting in a significant strengthening of reserves for this account at March 31, 2021. Loss emergence on the terminated commercial auto account in the second quarter was in line with our expectations, and accordingly, no additional reserve development was taken. In the third quarter, an additional $29.6 million was recognized as adverse loss and loss adjustment reserve development upon entering the loss portfolio transaction as described below. The Company experienced $2.5 million of net favorable development in the Specialty Admitted Insurance segment due to favorable development in the workers' compensation business for prior accident years, and $22.6 million of net adverse development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the nine months ended September 30, 2021 related to Hurricane Ida. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

Loss Portfolio Transfers

Loss portfolio transfers are a form of reinsurance utilized by the Company to transfer losses and loss adjustment expenses and associated risk of adverse development on covered subject business, as defined in the respective agreements, to an assuming reinsurer in exchange for a reinsurance premium. Loss portfolio transfers can bring economic finality on the subject risks when they no longer meet the Company's appetite or are no longer aligned with our risk management guidelines.

The Company periodically reevaluates the remaining reserves subject to its loss portfolio transfers, and when recognized adverse prior year development on the subject business causes the cumulative amounts ceded under a loss portfolio transfer to exceed the consideration paid, the loss portfolio transfer moves into a gain position subject to retroactive reinsurance accounting under GAAP. Gains are deferred under retroactive reinsurance accounting and recognized in earnings in proportion to actual paid recoveries under the loss portfolio transfer using the recovery method. While the deferral of gains can introduce volatility in our results in the short-term, over the life of the contract, we would expect no economic impact to the Company as long as any additional losses are within the limit of the loss portfolio transfer and the counterparty performs under the contract. The impact of retroactive reinsurance accounting is not indicative of our current and ongoing operations.

Loss Portfolio Transfer Retrocession Agreement

On February 23, 2022, JRG Re entered into a loss portfolio transfer retrocession agreement (the “Retrocession Agreement”) with Fortitude Reinsurance Company Ltd. (“FRL”) under which FRL reinsures the majority of the reserves in the Company’s Casualty Reinsurance segment. Under the terms of the transaction, which closed on March 31, 2022 (the “Retrocession Closing Date”), JRG Re (a) ceded to FRL all existing and future claims for losses arising under certain casualty reinsurance agreements with underlying insurance companies with treaty inception dates ranging from 2011 to 2020 (the “Subject Business”), in each case net of third-party reinsurance and other recoveries, up to an aggregate limit of $400.0 million; (b) continues to manage and retain the benefit of other third-party reinsurance on the Subject Business; (c) paid FRL a reinsurance premium of $335.0 million, $310.0 million of which JRG Re credited to a notional funds withheld account (the “Funds Withheld Account”) and $25.0 million of which was paid in cash to FRL; and (d) pays FRL a 2% per annum crediting rate on the Funds Withheld Account balance on a quarterly basis. The total premium, initial Funds Withheld Account credit, and aggregate limit was adjusted for claims paid from October 1, 2021 to the Retrocession Closing Date. The Casualty

Reinsurance segment incurred losses of $11.5 million (including $6.8 million of net adverse reserve development and $4.7 million of current accident year losses) in the three months ended March 31, 2022 associated with the Retrocession Agreement.

Commercial Auto Loss Portfolio Transfer

On September 27, 2021, James River Insurance Company and James River Casualty Company (together, “James River”) entered into a loss portfolio transfer transaction (the “Commercial Auto LPT”) with Aleka Insurance, Inc. (“Aleka”), a captive insurance company affiliate of Rasier LLC, to reinsure substantially all of the Excess and Surplus Lines segment's legacy portfolio of commercial auto policies previously issued to Rasier LLC and its affiliates (collectively, “Rasier”) for which James River is not otherwise indemnified by Rasier. Under the terms of the transaction, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier policies written in the years 2013-2019, which amount constituted the reinsurance premium. The reinsurance coverage is structured to be fully collateralized, is not subject to an aggregate limit, and is subject to certain exclusions. A pre-tax loss of $29.6 million was recognized as adverse loss and loss adjustment reserve development in the Excess and Surplus Lines segment for the third quarter of 2021 associated with the loss portfolio transfer.

For the three and nine months ended September 30, 2022, due to adverse paid loss trends on the legacy Rasier business, the Company recognized adverse prior year development of $46.7 million on the reserves subject to the Commercial Auto LPT, resulting in a corresponding additional amount ceded under the Commercial Auto LPT. As a result, the cumulative amounts ceded under the Commercial Auto LPT exceed the consideration paid, moving the Commercial Auto LPT into a gain position. The Company has applied retroactive reinsurance accounting to the Commercial Auto LPT. A retroactive reinsurance benefit of $25.9 million was recorded in losses and loss adjustment expenses on the Condensed Consolidated Statements of (Loss) Income and Comprehensive Loss for the three and nine months ended September 30, 2022 using the recovery method. As of September 30, 2022 and December 31, 2021, the cumulative amounts ceded under the Commercial Auto LPT were $391.8 million and $345.1 million, respectively. The unrecognized deferred retroactive reinsurance gain of $20.8 million at September 30, 2022 is separately presented on the Company's Condensed Consolidated Balance Sheets.

6.    Other Comprehensive Loss

The following table summarizes the components of other comprehensive loss:

The Company's invested assets at September 30, 2022 include $1,639.2 million of fixed maturity securities that are classified as available-for-sale and carried at fair value with unrealized gains and losses on these securities reported, net of applicable taxes, as a separate component of accumulated comprehensive (loss) income. In the nine months ended September 30, 2022 and 2021, the fair values of our fixed maturity securities were negatively impacted by rising interest rates leading to unrealized losses recognized in other comprehensive loss.

JAMES RIVER GROUP HOLDING, LTD. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (continued)

In addition to the $972,000 of net realized investment losses and $284,000 of net realized investment gains on available-for-sale fixed maturities for the three and nine months ended September 30, 2022 ($3.2 million and $4.3 million of net realized investment gains for the three and nine months ended September 30, 2021, respectively), the Company also recognized net realized and unrealized investment losses in the respective periods of $2.2 million and $14.2 million on its investments in bank loan participations ($195,000 and $6.0 million of net realized and unrealized investment gains in the respective prior year periods) and net realized and unrealized investment losses of $4.6 million and $15.9 million on its investments in equity securities ($641,000 and $3.4 million of net realized and unrealized investment gains in the respective prior year periods) that was largely related to preferred stock holdings.

7.       Contingent Liabilities

The Company is involved in various legal proceedings, including commercial matters and litigation regarding insurance claims arising in the ordinary course of business as well as an alleged class action lawsuit. In addition, the Company is involved from time to time in legal actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in the handling of insurance claims. The Company believes that the outcome of such matters, individually and in the aggregate, is not reasonably likely to have a material adverse effect on its consolidated financial position, results of operations or cash flows.

On July 9, 2021 a purported class action lawsuit was filed in the U.S. District Court, Eastern District of Virginia (the “Court”) by Employees’ Retirement Fund of the City of Fort Worth against James River Group Holdings, Ltd. and certain of its present and former officers (together, “Defendants”). On September 22, 2021, the Court entered an order appointing Employees’ Retirement Fund of the City of Fort Worth and the City of Miami General Employees’ and Sanitation Employees’ Retirement Trust as co-lead plaintiffs (together, “Plaintiffs”). Plaintiffs’ consolidated amended complaint was filed on November 19, 2021 (the “First Amended Complaint”). The Defendants filed a motion to dismiss the First Amended Complaint on January 18, 2022, Plaintiffs’ opposition thereto was filed on March 4, 2022, and the Defendants’ reply to the Plaintiffs’ opposition was filed on April 4, 2022. On August 25, 2022, Plaintiffs filed a motion for leave to file a second amended class action complaint (the "Second Amended Complaint"). On September 8, 2022, the Defendants consented to the Plaintiffs’ motion to file the Second Amended Complaint, and filed a motion to dismiss the Second Amended Complaint on October 24, 2022 (the "Second MTD"). The Plaintiffs’ opposition to the Second MTD is due December 8, 2022, and the Defendant's reply to the Plaintiffs’ opposition is due January 9, 2023. The First Amended Complaint and Second Amended Complaint assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of persons and entities that purchased the Company's stock between February 22, 2019 and October 25, 2021, and allege that Defendants failed to make appropriate disclosures concerning the adequacy of reserves for policies that covered Rasier LLC, a subsidiary of Uber Technologies, Inc., and seek unspecified damages, costs, attorneys’ fees and such other relief as the court may deem proper. We believe that the Plaintiffs’ claims are without merit and we intend to vigorously defend this lawsuit.

For a description of the potential future impacts of COVID-19 on the Company, see the “The global coronavirus outbreak could harm business and results of operations of the Company” risk factor in Part I—Item IA in our Annual Report on Form 10-K for the year ended December 31, 2021.

The Company’s reinsurance subsidiary, JRG Re, entered into three letter of credit facilities with banks as security to third-party reinsureds on reinsurance assumed by JRG Re. JRG Re has established custodial accounts to secure these letters of credit. Under a $30.0 million facility, $4.6 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $7.8 million. Under a $102.5 million facility, $40.5 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $46.0 million. Under a $100.0 million facility, $22.6 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $27.5 million. JRG Re has also established trust accounts to secure its obligations to selected reinsureds. The total amount deposited in the trust accounts for the benefit of third-party reinsureds was $409.3 million at September 30, 2022.

Amounts Recoverable from an Indemnifying Party and Reinsurer on Legacy Commercial Auto Book

James River previously issued a set of commercial auto insurance contracts (the “Rasier Commercial Auto Policies”) to Rasier under which James River pays losses and loss adjustment expenses on the contracts. James River has indemnity agreements with Rasier (non-insurance entities) (collectively, the “Indemnity Agreements”) and is contractually entitled to reimbursement for the portion of the losses and loss adjustment expenses paid on behalf of Rasier under the Rasier Commercial Auto Policies and other expenses incurred by James River. On September 27, 2021, James River entered into the Commercial Auto LPT with Aleka to reinsure substantially all of the Rasier Commercial Auto Policies for which James River is not otherwise indemnified by Rasier under the Indemnity Agreements. Under the terms of the Commercial Auto LPT, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier Commercial Auto Policies written in the years 2013-2019, which amount constituted the reinsurance premium.

JAMES RIVER GROUP HOLDING, LTD. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (continued)

Each of Rasier and Aleka are required to post collateral under the Indemnity Agreements and the Commercial Auto LPT, respectively:

•Pursuant to the Indemnity Agreements, Rasier is required to post collateral equal to 102% of James River's estimate of the amounts that are recoverable or may be recoverable under the indemnity agreements, including, among other things, case loss and loss adjustment expense reserves, IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess policy limits liabilities. The collateral is provided through a collateral trust arrangement (the “Indemnity Trust”) in favor of James River by Aleka. In connection with the execution of the Commercial Auto LPT, James River returned $691.3 million to the Indemnity Trust, representing the remaining balance of the amount withdrawn in October 2019, as was permitted under the indemnification agreements with Rasier and the associated trust agreement. At September 30, 2022, the balance in the Indemnity Trust was $262.1 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Indemnity Agreements as described below, the total balance of collateral securing Rasier’s obligations under the Indemnity Agreements was $331.3 million.

•Pursuant to the Commercial Auto LPT, Aleka is required to post collateral equal to 102% of James River's estimate of Aleka's obligations under the Commercial Auto LPT, calculated in accordance with statutory accounting principles. The collateral is provided through a collateral trust arrangement (the “LPT Trust”) established in favor of James River by Aleka. At September 30, 2022, the balance in the LPT Trust was $118.3 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Commercial Auto LPT as described below, the total balance of collateral securing Aleka’s obligations under the Commercial Auto LPT was $146.5 million. At September 30, 2022, the total reinsurance recoverables under the Commercial Auto LPT was $189.1 million (including $174.3 million of unpaid recoverables and $14.8 million of paid recoverables).

In connection with the execution of the Commercial Auto LPT, James River and Aleka entered into an administrative services agreement (the “Administrative Services Agreement”) with a third party claims administrator (the “Administrator”) pursuant to which the Administrator handles the claims on the Rasier Commercial Auto Policies for the remaining life of those claims. The claims paid by the Administrator are reimbursable by James River, and pursuant to the Administrative Services Agreement, James River established a loss fund trust account for the benefit of the Administrator (the “Loss Fund Trust”) to collateralize its claims payment reimbursement obligations. James River funds the Loss Fund Trust using funds withdrawn from the Indemnity Trust, funds withdrawn from the LPT Trust, and its own funds, in each case in an amount equal to the pro rata portion of the required Loss Fund Trust balance attributable to the Indemnity Agreements, the Commercial Auto LPT and James River’s existing third party reinsurance agreements, respectively. At September 30, 2022, the balance in the Loss Fund Trust was $102.5 million, including $69.2 million representing collateral supporting Rasier’s obligations under the Indemnity Agreements and $28.2 million representing collateral supporting Aleka’s obligations under the Commercial Auto LPT. Funds posted to the Loss Fund Trust are classified as restricted cash equivalents on the Company's balance sheets.

While the Commercial Auto LPT brings economic finality to substantially all of the Rasier Commercial Auto Policies, the Company has credit exposure to Rasier and Aleka under the Indemnity Agreements and the Commercial Auto LPT if the estimated losses and expenses of the Rasier Commercial Auto Policies grow at a faster pace than the growth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and loss adjustment expenses and other amounts recoverable under the Indemnity Agreements and the Commercial Auto LPT, which are the basis for establishing the collateral balances, are lower than actual amounts paid or payable. The amount of our credit exposure in any of these instances could be material. To mitigate these risks, we closely and frequently monitor our exposure compared to our collateral held, and we request additional collateral in accordance with the terms of the Commercial Auto LPT and Indemnity Agreements when our analysis indicates that we have uncollateralized exposure.

8.    Segment Information

The Company has four reportable segments: the Excess and Surplus Lines segment, the Specialty Admitted Insurance segment, the Casualty Reinsurance segment, and the Corporate and Other segment. Segment profit (loss) is measured by underwriting profit (loss), which is generally defined as net earned premiums and gross fee income (in specific instances when the Company is not retaining insurance risk) in “other income” in the condensed consolidated statements of income (loss) and comprehensive (loss) income less loss and loss adjustment expenses on business not subject to retroactive reinsurance accounting for loss portfolio transfers (see Loss Portfolio Transfers in Note 5 - Reserve for Losses and Loss Adjustment Expenses) and other operating expenses of the operating segments. Gross fee income of $914,000 and $2.6 million for the Specialty Admitted Insurance segment was included in other income and in underwriting profit (loss) for the three and nine months ended September 30, 2022, respectively ($1.0 million and $2.9 million in the respective prior year periods). Segment results are reported prior to the effects of intercompany reinsurance agreements among the Company’s insurance subsidiaries.

10.    Fair Value Measurements

Three levels of inputs are used to measure fair value of financial instruments: (1) Level 1: quoted price (unadjusted) in active markets for identical assets, (2) Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument, and (3) Level 3: inputs to the valuation methodology are unobservable for the asset or liability.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date.

The fair values of fixed maturity securities, equity securities, and bank loan participations have been determined using fair value prices provided by the Company’s investment accounting services provider or investment managers, who utilize internationally recognized independent pricing services. The prices provided by the independent pricing services are generally

25

JAMES RIVER GROUP HOLDING, LTD. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (continued)

based on observable market data in active markets (e.g. broker quotes and prices observed for comparable securities). Values for U.S. Treasury and publicly-traded equity securities are generally based on Level 1 inputs which use the market approach valuation technique. The values for all other fixed maturity securities (including state and municipal securities and obligations of U.S. government corporations and agencies) and bank loan participations generally incorporate significant Level 2 inputs, and in some cases, Level 3 inputs, using the market approach and income approach valuation techniques. There have been no changes in the Company’s use of valuation techniques since December 31, 2020.

The Company reviews fair value prices provided by its outside investment accounting service provider or investment managers for reasonableness by comparing the fair values provided by the managers to those provided by its investment custodian. The Company also reviews and monitors changes in unrealized gains and losses. The Company has not historically adjusted security prices. The Company obtains an understanding of the methods, models and inputs used by the investment managers and independent pricing services, and controls are in place to validate that prices provided represent fair values. The Company’s control process includes, but is not limited to, initial and ongoing evaluation of the methodologies used, a review of specific securities and an assessment for proper classification within the fair value hierarchy, and obtaining and reviewing internal control reports for our investment manager that obtains fair values from independent pricing services.

The Company had one equity security at December 31, 2021 for which the fair value was determined using significant unobservable inputs (Level 3). The fair value of $102,000 for the equity security was based on expected proceeds from its sale. During the nine months ended September 30, 2022, the Company sold the equity security.

The Company held one bank loan participation and three equity securities at September 30, 2021 and one bank loan participation and two equity securities at December 31, 2020 for which the fair value was determined using significant unobservable inputs (Level 3). A market approach using prices in trades of comparable securities was utilized to determine a fair value for the securities of $372,000 at September 30, 2021 and $980,000 at December 31, 2020.

JAMES RIVER GROUP HOLDING, LTD. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (continued)

Transfers out of Level 3 occur when the Company is able to obtain reliable prices from pricing vendors for securities for which the Company was previously unable to obtain reliable prices. Transfers in to Level 3 occur when the Company is unable to obtain reliable prices for securities from pricing vendors and instead must use broker price quotes to value the securities.

There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2022 or 2021. The Company recognizes transfers between levels at the beginning of the reporting period.

In the determination of the fair value for bank loan participations and certain high yield bonds, the Company’s investment manager endeavors to obtain data from multiple external pricing sources. External pricing sources may include brokers, dealers and price data vendors that provide a composite price based on prices from multiple dealers. Such external pricing sources typically provide valuations for normal institutional size trading units of such securities using methods based on market transactions for comparable securities, and various relationships between securities, as generally recognized by institutional dealers. For investments in which the investment manager determines that only one external pricing source is appropriate or if only one external price is available, the relevant investment is generally recorded at fair value based on such price.

Investments for which external sources are not available or are determined by the investment manager not to be representative of fair value are recorded at fair value as determined by the Company, with input from its investment managers and valuation specialists as considered necessary. In determining the fair value of such investments, the Company considers one or more of the following factors: type of security held, convertibility or exchangeability of the security, redeemability of the security (including the timing of redemptions), application of industry accepted valuation models, recent trading activity, liquidity, estimates of liquidation value, purchase cost, and prices received for securities with similar terms of the same issuer or similar issuers. At September 30, 2022 and December 31, 2021, there were no investments for which external sources were unavailable to determine fair value.

The carrying values and fair values of financial instruments are summarized below:

Junior subordinated debt	104,055		115,000		104,055		106,635

The fair values of fixed maturity securities, equity securities, and bank loan participations have been determined using quoted market prices for securities traded in the public market or prices using bid or closing prices for securities not traded in the public marketplace. The fair values of cash and cash equivalents and short-term investments approximate their carrying values due to their short-term maturity.

The fair values of other invested assets-notes receivable, senior debt, and junior subordinated debt at September 30, 2022 and December 31, 2021 were determined by calculating the present value of expected future cash flows under the terms of the note agreements or debt agreements, as applicable, discounted at an estimated market rate of interest at September 30, 2022 and December 31, 2021, respectively.

The fair values of senior debt and junior subordinated debt at September 30, 2022 and December 31, 2021 were determined using inputs to the valuation methodology that are unobservable (Level 3).

11.    Senior Debt

The Company repaid $40.0 million of loans that were outstanding under a credit agreement (the “2017 Facility”) in the three months ended March 31, 2022. At September 30, 2022, unsecured loans of $21.5 million and secured letters of credit

28

JAMES RIVER GROUP HOLDING, LTD. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (continued)

totaling $22.6 million were outstanding under the 2017 Facility. The 2017 Facility provides the Company with a revolving line of credit of up to $100.0 million, which may be used for loans and letters of credit made or issued, at the borrowers’ option, on a secured or unsecured basis. The 2017 Facility contains certain financial and other covenants which the Company was in compliance with at September 30, 2022.

12.    Series A Preferred Shares

On February 24, 2022, we entered into an Investment Agreement with GPC Partners Investments (Thames) LP (“GPC Partners”), an affiliate of Gallatin Point Capital LLC, relating to the issuance and sale of 150,000 7% Series A Perpetual Cumulative Convertible Preferred Shares, par value $0.00125 per share (the “Series A Preferred Shares”), for an aggregate purchase price of $150.0 million, or $1,000 per share, in a private placement. The transaction closed on March 1, 2022 (the “Series A Closing Date”).

The Series A Preferred Shares rank senior to our common shares with respect to dividend rights and rights on the distribution of assets on any liquidation, dissolution or winding up of the affairs of the Company, upon which the holders of Series A Preferred Shares would receive the greater of the $1,000 liquidation preference per share (the “Liquidation Preference”) plus accrued and unpaid dividends, or the amount they would have received if they had converted all of their Series A Preferred Shares to common shares immediately before such liquidation, dissolution or winding up.

Holders of the Series A Preferred Shares are entitled to a dividend at the initial rate of 7% of the Liquidation Preference per annum, paid in cash, in-kind in common shares or in Series A Preferred Shares, at our election. On the five-year anniversary of the Series A Closing Date, and each five-year anniversary thereafter, the dividend rate will reset to a rate equal to the five-year U.S. treasury rate plus 5.2%. Dividends accrue quarterly and are payable on March 31, June 30, September 30 and December 31 of each year. Cash dividends of $6.1 million have been paid in the nine months ended September 30, 2022, including $3.5 million on June 30, 2022 for the period from the Series A Closing Date through June 30, 2022, and $2.6 million on September 30, 2022.

The Series A Preferred Shares are convertible at the option of the holders thereof at any time into common shares at an initial conversion price of $26.5950, making the Series A Preferred Shares initially convertible into 5,640,158 common shares. The conversion price is subject to customary anti-dilution adjustments, including cash dividends on the common shares above specified levels, as well as certain adjustments in case of adverse reserve developments.

At any time on or after the two year anniversary of the Series A Closing Date, if the volume-weighted average price (“VWAP”) per Common Share is greater than 130% of the then-applicable conversion price for at least twenty (20) consecutive trading days, the Company will be able to elect to convert (a “Mandatory Conversion”) all of the outstanding Series A Preferred Shares into Common Shares. In the case of a Mandatory Conversion, each Series A Preferred Share then outstanding will be converted into (i) the number of Common Shares equal to the quotient of (A) the sum of the Liquidation Preference and the accrued and unpaid dividends with respect to such Series A Preferred Share to be converted divided by (B) the conversion price of such share in effect as of the date of the Mandatory Conversion plus (ii) cash in lieu of fractional shares.

Upon any Mandatory Conversion on or before the five-year anniversary of the Series A Closing Date, all dividends that would have accrued from the date of the Mandatory Conversion to the later of the five-year anniversary of the Series A Closing Date or the last day of the eighth quarter following the date of the Mandatory Conversion, the last eight quarters of which will be discounted to present value using a discount rate of 3.5% per annum, and will be immediately payable in Common Shares, valued at the average of the daily VWAP of the Company’s Common Shares during the five (5) trading days immediately preceding the Mandatory Conversion.

The holders of the Series A Preferred Shares may require us to repurchase their shares upon the occurrence of certain change of control events. Upon the occurrence of a Fundamental Change (as defined in the Certificate of Designations designating the Series A Preferred Shares), each holder of outstanding Series A Preferred Shares will be permitted to, at its election, (i) effective as of immediately prior to the Fundamental Change, convert all or a portion of its Series A Preferred Shares into Common Shares, or (ii) require the Company to repurchase any or all of such holder’s Series A Preferred Shares at a purchase price per Series A Preferred Share equal to the Liquidation Preference of such Series A Preferred Share plus accrued and unpaid dividends. The repurchase price will be payable in cash.

Because the Company may be required to repurchase all or a portion of the Series A Preferred Shares at the option of the holder upon the occurrence of certain change of control events, the Series A Preferred Shares have been classified as mezzanine equity in the Company's condensed consolidated balance sheets and are recognized at fair value of $150.0 million (the proceeds on the date of issuance) less issuance costs of $5.1 million, resulting in a carrying value of $144.9 million.

Under the terms of the Investment Agreement, GPC Partners has the right to designate one member of the Board (the “Series A Designee”). GPC Partners has designated Matthew Botein as the Series A Designee and, accordingly, the Board approved the appointment of Mr. Botein to serve as a Class I director with a term expiring at the 2024 annual meeting of the Company’s shareholders, effective following receipt of any necessary regulatory approvals. Until applicable regulatory approvals are obtained, Mr. Botein will have board observer status.

Equity Incentive Plans

The Company’s shareholders have approved various equity incentive plans, including the 2014 Long Term Incentive Plan (“2014 LTIP”) and the 2014 Non-Employee Director Incentive Plan (“2014 Director Plan”) (collectively, the “Plans”). All awards issued under the Plans are issued at the discretion of the Board of Directors.

Employees are eligible to receive non-qualified stock options, incentive stock options, share appreciation rights, performance shares, restricted shares, RSUs, and other awards under the 2014 LTIP. The maximum number of shares available for issuance under the 2014 LTIP is 4,171,150, and at September 30, 2022, 807,839 shares are available for grant.

On July 26, 2022, the Board of Directors of the Company approved a new long-term incentive plan (the “LTI Plan”). The LTI Plan is designed to align compensation of designated senior officers of the Company with Company performance and shareholder interests over the long-term. Awards under the LTI Plan will be made in the form of performance restricted share units (a “PRSU”) and service based restricted share units (RSUs), with initial awards intended to be made in February 2023.

Each PRSU will represent a contingent right to receive one Company common share based upon the level of achievement of certain performance metrics during the performance period, with payout for achievement of threshold, target and maximum performance levels to be set at 50%, 100% and 200% of the target number of PRSUs, respectively. The initial PRSU awards are intended to have a performance period of January 1, 2023 through December 31, 2025.

Non-employee directors of the Company are eligible to receive non-qualified stock options, share appreciation rights, performance shares, restricted shares, RSUs, and other awards under the 2014 Director Plan. The maximum number of shares available for issuance under the 2014 Director Plan is 150,000, and at September 30, 2022, 77,708 shares are available for grant.

Outstanding RSUs granted to employees generally vest ratably over a three year vesting period. RSUs granted to non-employee directors have a one year vesting period. The holders of RSUs are entitled to dividend equivalents. The dividend equivalents are settled in cash at the same time that the underlying RSUs vest and are subject to the same risk of forfeiture as the underlying shares. The fair value of the RSUs granted is based on the market price of the underlying shares at the date of grant.

On October 25, 2022, the Board of Directors granted an employee a restricted share unit award under the 2014 LTIP with an aggregate fair value of $350,000 and a grant date of November 3, 2022. The award vests in one installment on March 1, 2024.

At the 2022 annual general meeting of shareholders (the “Annual Meeting”) of the Company held on October 25, 2022, the Company’s shareholders approved an amendment (the “Second Amendment”) to the 2014 LTIP. The Board of Directors of the Company had previously approved the Second Amendment. The Second Amendment implements several changes to the 2014 LTIP including increasing the number of shares reserved for issuance under awards by 811,500 to a total of 4,982,650 shares.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors. Factors that could cause such differences are discussed in the sections entitled “Special Note Regarding Forward-Looking Statements”, and Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2022, or for any other future period. The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q, and in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021.

The accompanying condensed consolidated financial statements and related notes have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and include the accounts of James River Group Holdings, Ltd. and its subsidiaries. Unless the context indicates or suggests otherwise, references to “the Company”, “we”, “us” and “our” refer to James River Group Holdings, Ltd. and its subsidiaries.

Our Business

James River Group Holdings, Ltd. is a Bermuda-based holding company. We own and operate a group of specialty insurance and reinsurance companies with the objective of generating compelling returns on tangible equity while limiting underwriting and investment volatility. We seek to accomplish this by earning profits from insurance and reinsurance underwriting and generating meaningful risk-adjusted investment returns while managing our capital.

We are organized into four reportable segments, which are separately managed business units:

•The Excess and Surplus Lines segment offers commercial excess and surplus lines liability and property insurance in every U.S. state, the District of Columbia, Puerto Rico and the U.S. Virgin Islands through James River Insurance Company and its wholly-owned subsidiary, James River Casualty Company;

•The Specialty Admitted Insurance segment approaches the insurance market in two ways: as a risk bearing underwriter, and as a “fronting” company. The Company’s risk bearing underwriting is focused on niche classes within the standard insurance markets, such as workers’ compensation coverage for residential contractors, light manufacturing operations, transportation workers and healthcare workers. In its fronting business, the Specialty Admitted segment works with distributors, such as managing general agents and other producers, by using our licensure, rating and administrative services in order to produce and service insurance policies for reinsurers and other third party risk bearing entities. We charge fees for “fronting” for these capital providers. In some instances, we retain a small percentage of the risk on fronted business, generally 10%-30%. This segment has admitted licenses and the authority to write excess and surplus lines insurance in 50 states and the District of Columbia;

•The Casualty Reinsurance segment primarily provides proportional and working layer casualty reinsurance to third parties (primarily through reinsurance intermediaries) through JRG Reinsurance Company Ltd. (“JRG Re”). JRG Re has also in the past provided reinsurance to the Company’s U.S.-based insurance subsidiaries through a quota-share reinsurance agreement. Carolina Re Ltd (“Carolina Re”) was formed in 2018 to also provide reinsurance to the Company’s U.S.-based insurance subsidiaries through a quota-share reinsurance agreement, and was also the cedent on an aggregate stop loss reinsurance treaty with JRG Re through December 31, 2021. JRG Re and Carolina Re are both Bermuda-based reinsurance companies. Carolina Re made an irrevocable election to be taxed as a U.S. domestic corporation under Section 953(d) of the Internal Revenue Code of 1986, as amended, effective January 1, 2018.

•The Corporate and Other segment consists of the management and treasury activities of our holding companies, interest expense associated with our debt, and expenses of our holding companies, including public company expenses, that are not reimbursed by our insurance segments.

All of the Company’s U.S.-domiciled insurance subsidiaries are party to an intercompany pooling agreement that distributes the net underwriting results among the group companies based on their approximate pro-rata level of statutory capital and surplus to the total Company statutory capital and surplus. Additionally, each of the Company’s U.S.-domiciled insurance subsidiaries is a party to a quota share reinsurance agreement that in periods prior to January 1, 2018 ceded 70% of their premiums and losses to JRG Re, and from January 1, 2018 through December 31, 2021, ceded 70% of their premiums and losses to Carolina Re. During the three months ended September 30, 2022, Carolina Re commuted the majority of the outstanding obligations ceded under the intercompany quota-share reinsurance agreements back to the Company’s U.S.-based insurance subsidiaries with effect from January 1, 2022. We report all segment information in this ‘‘Management’s Discussion and Analysis of Financial Condition and Results of Operations’’ prior to the effects of intercompany reinsurance, consistent with the manner in which we evaluate the operating performance of our reportable segments.

All of our insurance and reinsurance subsidiaries have financial strength ratings of “A-” (Excellent) from A.M. Best Company.

Key Metrics

We discuss certain key metrics, described below, which we believe provide useful information about our business and the operational factors underlying our financial performance.

Underwriting profit is a non-GAAP measure commonly used in the property and casualty insurance industry to evaluate underwriting performance. We believe that the disclosure of underwriting profit by individual segment and of the Company as a whole is useful to investors, analysts, rating agencies and other users of our financial information in evaluating our performance because our objective is to consistently earn underwriting profits. We evaluate the performance of our segments and allocate resources based primarily on underwriting profit. We define underwriting profit as net earned premiums and gross fee income (in specific instances when the Company is not retaining insurance risk) less losses and loss adjustment expenses on business not subject to retroactive reinsurance accounting for loss portfolio transfers (see Loss Portfolio Transfers in Strategic Actions below) and other operating expenses. Other operating expenses include the underwriting, acquisition, and insurance expenses of the operating segments and, for consolidated underwriting profit, the expenses of the Corporate and Other segment. Our definition of underwriting profit may not be comparable to that of other companies. See “Reconciliation of Non-GAAP Measures” for a reconciliation of underwriting profit to income before taxes and for additional information.

Loss ratio, expressed as a percentage, is the ratio of losses and loss adjustment expenses on business not subject to retroactive reinsurance accounting for loss portfolio transfers to net earned premiums. Our definition of loss ratio may not be comparable to that of other companies. See “Underwriting Performance Ratios” for a reconciliation of underwriting ratios.

Accident year loss ratio, expressed as a percentage, is the ratio of losses and loss adjustment expenses for the current accident year (excluding development on prior accident year reserves) to net earned premiums.

Expense ratio, expressed as a percentage, is the ratio of other operating expenses net of gross fee income included in other income to net earned premiums.

Combined ratio is a measure of underwriting performance calculated as the sum of the loss ratio and the expense ratio. A combined ratio of less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss. Our definition of combined ratio may not be comparable to that of other companies. See “Underwriting Performance Ratios” for a reconciliation of underwriting ratios.

Adjusted net operating income is an internal performance measure used in the management of our operations. We believe it gives our management and other users of our financial information useful insight into our results of operations and our underlying business performance. Adjusted net operating income is defined as income available to common shareholders excluding a) the impact of retroactive reinsurance accounting for loss portfolio transfers, b) net realized and unrealized gains (losses) on investments, c) certain non-operating expenses such as professional service fees related to a purported class action lawsuit, various strategic initiatives, and the filing of registration statements for the offering of securities, and d) severance costs associated with terminated employees. Adjusted net operating income is a non-GAAP measure and should not be viewed as a substitute for net income calculated in accordance with GAAP. Our definition of adjusted net operating income may not be comparable to that of other companies. See “Reconciliation of Non-GAAP Measures” for a reconciliation of income available to common shareholders to adjusted net operating income.

Tangible equity is defined as shareholders' equity plus mezzanine Series A Preferred Shares (as defined below) and the unrecognized deferred retroactive reinsurance gain on loss portfolio transfers less goodwill and intangible assets, net of amortization. We believe tangible equity is a good measure to evaluate the strength of our balance sheet and to compare returns relative to this measure. Key financial measures that we use to assess our longer term financial performance include the percentage growth in our tangible equity per share and our return on tangible equity. Tangible equity is a non-GAAP measure and should not be viewed as a substitute for shareholders’ equity calculated in accordance with GAAP. Our definition of tangible equity may not be comparable to that of other companies. See “Reconciliation of Non-GAAP Measures” for a reconciliation of shareholders' equity to tangible equity.

Adjusted net operating return on tangible equity is defined as annualized adjusted net operating income expressed as a percentage of the average quarterly tangible equity balances in the respective period.

Tangible equity per share represents tangible equity divided by the sum of total common shares outstanding plus the common shares resulting from an assumed conversion of the outstanding Series A Preferred Shares into common shares (at the current conversion price).

Net retention is defined as the ratio of net written premiums to gross written premiums.

34

Gross investment return is annualized investment income before any deductions for fees and expenses, expressed as a percentage of the average beginning and ending carrying values of those investments during the period.

Unless specified otherwise, all references to our defined metrics above in this Management’s Discussion and Analysis of Financial Condition and Results of Operations are for our business that is not subject to retroactive reinsurance accounting for loss portfolio transfers. Management believes that the lack of economic impact of retroactive reinsurance accounting makes the presentation of our key metrics on business not subject to retroactive reinsurance accounting helpful to the users of our financial information. See “Underwriting Performance Ratios” and “Reconciliation of Non-GAAP Measures.”

Critical Accounting Policies and Estimates

In preparing the unaudited condensed consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates.

The most critical accounting policies involve significant estimates and include those used in determining the reserve for losses and loss adjustment expenses and investment valuation and impairment. For a detailed discussion of each of these policies, refer to our Annual Report on Form 10-K for the year ended December 31, 2021. There have been no significant changes to any of these policies during the current year.

Impact of the COVID-19 Pandemic

For a discussion of the impact of the coronavirus (COVID-19) pandemic and related economic conditions on the Company’s results for the year ended December 31, 2021, please see “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operation” in our Annual Report. The Company continues to monitor the impact that the ongoing coronavirus (COVID-19) pandemic may be having on the Company’s financial condition and results of operations.

Impact of Macroeconomic Events Including Higher Levels of Inflation and Rising Interest Rates

Current macroeconomic events including the war in Ukraine and sustained supply chain constraints stemming from the COVID-19 pandemic have led to higher levels of inflation. The Federal Reserve, attempting to gain control of inflation, has implemented a series of federal funds rate increases in 2022 with more expected in the near future. Interest rates, in response, have risen significantly in 2022 and fears of an impending economic slowdown have increased the likelihood of an economic recession, all of which have negatively impacted financial markets. The more immediate impacts to the Company are on our investment portfolio and investing results. Our investment portfolio is primarily comprised of fixed maturity investments (75.3% of total invested assets at September 30, 2022). The fair values of fixed maturities generally move inversely with interest rates, and unrealized losses associated with the declines in fair values are recognized as a component of other comprehensive income, contributing to declines in shareholders' equity and tangible equity. For the nine months ended September 30, 2022, other comprehensive loss, representing the after-tax impact of the unrealized losses on fixed maturity investments, was $205.2 million. We are monitoring our portfolio for signs of credit-related impairments, and to date, we have concluded that the declines are primarily market-driven with no allowance for credit losses considered necessary. As turnover has occurred in our portfolio and we invest cash generated from operations, we are benefiting from the higher yields now available on fixed maturities which is reflected in our investment income. Our investment portfolio also contains investments in equity securities and bank loan participations (comprising 5.4% and 7.4% of total invested assets at September 30, 2022, respectively) that are carried on our Balance Sheets at fair value. The fair values of these investments, the changes in which are recognized as unrealized gains and losses in our Statements of (Loss) Income and Comprehensive Loss, have been negatively impacted by the ongoing macroeconomic events and associated declines in financial markets. Net realized and unrealized (losses) gains on investments for the nine months ended September 30, 2022 include unrealized losses of $16.0 million and $13.8 million, respectively, for the changes in fair values of equity securities and bank loan participations. The rising interest rates have also increased interest expense on our outstanding variable rate senior and trust preferred debt. The applicable rates on our debt reset quarterly or semi-annually and are structured as LIBOR plus a margin or spread.

Strategic Actions

Issuance of Series A Preferred Shares

The Company closed on the issuance and sale of 150,000 7% Series A Perpetual Cumulative Convertible Preferred Shares, par value $0.00125 per share (the “Series A Preferred Shares”) on March 1, 2022 for an aggregate purchase price of $150.0 million, or $1,000 per share, in a private placement. The Series A Preferred Shares are convertible into the Company’s common shares at the option of the holder at any time, or at the Company’s option under certain circumstances. Dividends on the Series A preferred shares accrue quarterly at the initial rate of 7% of the $1,000 liquidation preference per share (the “Liquidation Preference”) per annum, which may be paid in cash, in-kind in common shares or in Series A Preferred Shares, at the

35

Company’s election. Dividends declared and paid on the Series A Preferred Shares in the nine months ended September 30, 2022 (which represent the dividends from March 1, 2022, the date of issuance of the Series A Preferred Shares, through September 30, 2022) were $6.1 million. Please see “Part I—Item 1—Note 12. Series A Preferred Shares” in the Notes to our Condensed Consolidated Financial Statements in this Form 10-Q.

Loss Portfolio Transfers

Loss portfolio transfers are a form of reinsurance utilized by the Company to transfer losses and loss adjustment expenses and associated risk of adverse development on covered subject business, as defined in the respective agreements, to an assuming reinsurer in exchange for a reinsurance premium. Loss portfolio transfers can bring economic finality on the subject risks when they no longer meet the Company's appetite or are no longer aligned with our risk management guidelines.

The Company periodically reevaluates the remaining reserves subject to its loss portfolio transfers, and when recognized adverse prior year development on the subject business causes the cumulative amounts ceded under a loss portfolio transfer to exceed the consideration paid, the loss portfolio transfer moves into a gain position subject to retroactive reinsurance accounting under GAAP. Gains are deferred under retroactive reinsurance accounting and recognized in earnings in proportion to actual paid recoveries under the loss portfolio transfer using the recovery method. While the deferral of gains can introduce volatility in our results in the short-term, over the life of the contract, we would expect no economic impact to the Company as long as any additional losses are within the limit of the loss portfolio transfer and the counterparty performs under the contract. The impact of retroactive reinsurance accounting is not indicative of our current and ongoing operations.

Loss Portfolio Transfer Retrocession Agreement

On February 23, 2022, JRG Re entered into a loss portfolio transfer retrocession agreement (the “Retrocession Agreement”) with Fortitude Reinsurance Company Ltd. (“FRL”) under which FRL reinsures the majority of the reserves in the Company’s Casualty Reinsurance segment. Under the terms of the transaction, which closed on March 31, 2022 (the “Retrocession Closing Date”), JRG Re (a) ceded to FRL all existing and future claims for losses arising under certain casualty reinsurance agreements with underlying insurance companies with treaty inception dates ranging from 2011 to 2020 (the “Subject Business”), in each case net of third-party reinsurance and other recoveries, up to an aggregate limit of $400.0 million; (b) continues to manage and retain the benefit of other third-party reinsurance on the Subject Business; (c) paid FRL a reinsurance premium of $335.0 million, $310.0 million of which JRG Re credited to a notional funds withheld account (the “Funds Withheld Account”) and $25.0 million of which was paid in cash to FRL; and (d) pays FRL a 2% per annum crediting rate on the Funds Withheld Account balance on a quarterly basis. For the nine months ended September 30, 2022, Funds Withheld Account crediting fees of $2.6 million are included in interest expense in our Statements of (Loss) Income and Comprehensive Loss. The total premium, initial Funds Withheld Account credit, and aggregate limit was adjusted for claims paid from October 1, 2021 to the Retrocession Closing Date. The Casualty Reinsurance segment incurred losses of $11.5 million (including $6.8 million of net adverse reserve development and $4.7 million of current accident year losses) in the three months ended March 31, 2022 associated with the Retrocession Agreement.

Commercial Auto Loss Portfolio Transfer

On September 27, 2021, James River Insurance Company and James River Casualty Company (together, “James River”) entered into a loss portfolio transfer transaction (the “Commercial Auto LPT”) with Aleka Insurance, Inc. (“Aleka”), a captive insurance company affiliate of Rasier LLC, to reinsure substantially all of the Excess and Surplus Lines segment’s legacy portfolio of commercial auto policies previously issued to Rasier LLC and its affiliates (collectively, “Rasier”) for which James River is not otherwise indemnified by Rasier. Under the terms of the transaction, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier policies written in the years 2013-2019, which amount constituted the reinsurance premium. The reinsurance coverage is structured to be fully collateralized, is not subject to an aggregate limit, and is subject to certain exclusions. A pre-tax loss of $29.6 million was recognized as adverse loss and loss adjustment reserve development in the Excess and Surplus Lines segment for the third quarter of 2021 associated with the loss portfolio transfer.

For the three and nine months ended September 30, 2022, due to adverse paid loss trends on the legacy Rasier business, the Company recognized adverse prior year development of $46.7 million on the net reserves subject to the Commercial Auto LPT, resulting in a corresponding additional amount ceded under the Commercial Auto LPT. As a result, the cumulative amounts ceded under the Commercial Auto LPT exceed the consideration paid, moving the Commercial Auto LPT into a gain position. The Company has applied retroactive reinsurance accounting to the Commercial Auto LPT. A retroactive reinsurance benefit of $25.9 million was recorded in losses and loss adjustment expenses on the Condensed Consolidated Statements of (Loss) Income and Comprehensive Loss for the three and nine months ended September 30, 2022 using the recovery method. As of September 30, 2022 and December 31, 2021, the cumulative amounts ceded under the Commercial Auto LPT were $391.8 million and $345.1 million, respectively. The unrecognized deferred retroactive reinsurance gain of $20.8 million at September 30, 2022 is separately presented on the Company's Condensed Consolidated Balance Sheets.

(1)Underwriting profit (loss) and adjusted net operating income (loss) are non-GAAP measures. See “Reconciliation of Non-GAAP Measures.”

(2)Included in underwriting results for the three and nine months ended September 30, 2022 is gross fee income of $5.9 million and $17.4 million, respectively ($5.6 million and $16.2 million in the respective prior year periods).

(3)Accident year loss ratio excluding $5.0 million of net catastrophe losses related to Hurricane Ian in the three and nine months ended September 30, 2022 and $5.0 million of net catastrophe losses related to Hurricane Ida in the three and nine months ended September 30, 2021.

Three Months Ended September 30, 2022 and 2021

The Company produced an underwriting profit of $11.3 million and a combined ratio of 94.1% for the three months ended September 30, 2022 compared to an underwriting loss of $37.6 million and a combined ratio of 122.1% for the same period in the prior year.

Net earned premiums grew by $19.6 million or 11.5% over the prior year driven by the Excess and Surplus Lines segment. Net earned premiums for the Excess and Surplus Lines segment grew by $19.3 million or 16.1% due to favorable market conditions and growth in the book. Our loss ratio improved from 97.3% in the prior year to 69.5% in the current year. The

37

improvement was primarily driven by net reserve development on prior accident years which was $1.1 million or 0.6 percentage points favorable for the three months ended September 30, 2022 compared to $44.1 million or 25.8 percentage points of net adverse development in the three months ended September 30, 2021. The net adverse development in the prior year included $29.6 million in the Excess and Surplus Lines segment recognized with the loss portfolio transfer transaction with Aleka that was effective July 1, 2021 (discussed above) and $15.1 million in the Casualty Reinsurance segment.

Underwriting results in both periods include hurricane catastrophe losses in our small Excess Property book within the Excess and Surplus Lines segment. The Excess and Surplus Lines segment has a surplus share reinsurance treaty in effect that was specifically designed to cover property risks. The surplus share treaty along with facultative reinsurance helps ensure that our net retained limit per risk will be $5.0 million or less. In the three months ended September 30, 2022, the Company recorded $5.0 million (2.6 points) of net catastrophe losses for Hurricane Ian. In the three months ended September 30, 2021, the Company recorded $5.0 million (2.9 points) of net catastrophe losses for Hurricane Ida.

Underwriting results in the prior year were also negatively impacted by $8.1 million of reinstatement premium, including $6.4 million triggered by one claim on a 2019 excess of loss treaty in the Excess and Surplus Lines segment. The reinstatement premium reduced net written and net earned premium in the quarter and increased the underwriting loss.

As discussed above, the Company recognized adverse prior year development of $46.7 million on the reserves subject to the Commercial Auto LPT in the three months ended September 30, 2022, resulting in a corresponding additional amount ceded under the Commercial Auto LPT and requiring retroactive reinsurance accounting. A retroactive reinsurance benefit of $25.9 million was recorded in losses and loss adjustment expenses for the three months ended September 30, 2022, resulting in a net impact of $20.8 million within our net losses and loss adjustment expenses for the current period. Higher interest rates in the current year helped to boost yields in our fixed income portfolio and increase investment income, but also resulted in higher interest expense on our variable rate senior and trust preferred debt. Interest expense for the three months ended September 30, 2022 also includes $1.2 million of crediting fees on the Funds Withheld Account balance under the Retrocession Agreement. The unfavorable swing in net realized and unrealized gains and losses on investments (see Investing Results below) also had a negative impact on the comparative net results for the two periods as market values of equity securities and bank loan participations have declined in the current year due to the effect of macroeconomic events on financial markets. Net income available to common shareholders for the three months ended September 30, 2022 reflects the $2.6 million of current quarter dividends on the Series A Preferred Shares.

Adjusted net operating income (loss) increased from a loss of $26.8 million in the three months ended September 30, 2021 to income of $15.5 million in the three months ended September 30, 2022. The turnaround was primarily driven by the improved underwriting results in the current year. Tangible equity and tangible equity per share both declined by 9.0% in the current quarter mainly due to the impact of rising interest rates, which led to $60.7 million of unrealized losses on our fixed maturity investments in other comprehensive loss. The unrealized losses are discussed further in Investing Results below. Our 12.4% adjusted net operating return on tangible equity for the three months ended September 30, 2022 compared to a loss of 17.4% for the three months ended September 30, 2021.

Nine Months Ended September 30, 2022 and 2021

The Company produced an underwriting profit of $33.0 million and a combined ratio of 94.2% for the nine months ended September 30, 2022 compared to an underwriting loss of $179.2 million and a combined ratio of 135.6% for the same period in the prior year.

Consistent with the discussion of the three months above, attractive market conditions, particularly in our Excess and Surplus Lines segment, have allowed us to grow both written and earned premiums year-to-date. The Excess and Surplus Lines segment is our largest segment, comprising 60.4% of consolidated gross written premiums and 72.1% of consolidated net earned premiums year-to-date. Net earned premiums for the Excess and Surplus Lines segment increased $56.9 million or 16.2% over the prior year. Net earned premiums for our Specialty Admitted Insurance and Casualty Reinsurance segments also increased by $627,000 and $4.9 million over the prior year, respectively. The higher net earned premiums helped produce a lower expense ratio in the nine months ended September 30, 2022 as we saw growth in lines with meaningful ceding commissions and general and administrative expenses did not increase proportionately with the increase in earned premiums. Our expense ratio also benefited from 7.3% growth in fee income for our Specialty Admitted Insurance segment and lower commissions in our Casualty Reinsurance segment due to the mix of business and commission slides.

The loss ratio for the nine months ended September 30, 2022 includes $4.1 million, or 0.7 percentage points, of net adverse reserve development on prior accident years. As outlined in the “Strategic Actions” above, on February 23, 2022, JRG Re entered into the Retrocession Agreement to reinsure the majority of the Casualty Reinsurance segment's reserves. The Casualty Reinsurance segment incurred losses of $11.5 million associated with the Retrocession Agreement, including $6.8 million of net adverse reserve development on prior accident years and $4.7 million of current accident year losses, and representing 2.0 points of our loss ratio for the nine months ended September 30, 2022. The $6.8 million of net adverse development in the Casualty Reinsurance segment was partially offset by $2.8 million of net favorable reserve development on prior accident years

38

in the Specialty Admitted Insurance segment in the nine months ended September 30, 2022. The loss ratio for the nine months ended September 30, 2021 included $210.8 million (41.8 percentage points) of net adverse reserve development on prior accident years, including $190.7 million of net adverse development from the Excess and Surplus Lines segment almost entirely related to a previously canceled commercial auto account (see Segment Results below for further discussion). Current accident year losses in both nine month periods include $5.0 million of net catastrophe losses (Hurricane Ian in the current year and Hurricane Ida in the prior year) as discussed above in the three month comparative section. The higher current accident year loss ratio excluding catastrophe losses (67.1% compared to 66.2% for the nine months ended September 30, 2021) largely reflects current actuarial indications and higher loss trends in our Specialty Admitted Insurance segment and the $4.7 million of current accident year losses in the Casualty Reinsurance segment associated with the Retrocession Agreement.

Underwriting results in the prior year were also negatively impacted by $8.1 million of reinstatement premium, including $6.4 million triggered by one claim on a 2019 excess of loss treaty in the Excess and Surplus Lines segment. The reinstatement premium reduced net written and net earned premium and increased the underwriting loss.

Our net income increased over the prior year due to the improved underwriting results and higher net investment income boosted by higher yields in the current year, with partially offsetting items including the $20.8 million of retroactive reinsurance losses and loss adjustment expenses under the Commercial Auto LPT (see Three Months Ended September 30, 2022 and 2021), the unfavorable swing in net realized and unrealized gains and losses on investments (see Investing Results), and higher interest expense. Interest expense for the nine months ended September 30, 2022 includes $2.6 million of crediting fees on the Funds Withheld Account balance under the Retrocession Agreement. Net income available to common shareholders for the nine months ended September 30, 2022 reflects the $6.1 million of current year dividends on the Series A Preferred Shares issued March 1, 2022.

Adjusted net operating income (loss) improved from a $116.8 million loss in the nine months ended September 30, 2021 to income of $49.4 million in the nine months ended September 30, 2022. Tangible equity decreased by 6.4% year-to-date as net income of $13.2 million and proceeds from the Series A Preferred Share issuance of $144.9 million were offset by $205.2 million of unrealized losses on our fixed maturity investments in other comprehensive loss (see Investing Results below). Tangible equity per share decreased by 18.8% year-to-date reflecting the decrease in tangible equity over a larger share count including an assumed conversion of the Series A Preferred Shares. Our year-to-date adjusted net operating return on tangible equity of 12.7% compares favorably to the prior year loss of 27.9% and reflects the turnaround in underwriting results.

Premiums

Insurance premiums are earned ratably over the terms of our insurance policies, generally twelve months. Reinsurance premiums assumed are earned over the terms of the underlying policies or reinsurance contracts. Reinsurance contracts written on a “losses occurring” basis cover claims that may occur during the term of the contract or underlying insurance policy, which is typically twelve months. Reinsurance contracts which are written on a “risks attaching” basis cover claims which attach to the underlying insurance policies written during the terms of such contracts. Premiums earned on such contracts usually extend beyond the original term of the reinsurance contract, typically resulting in recognition of premiums earned over a 24-month period or more in proportion to the level of underlying exposure.

Gross written premiums for the Excess and Surplus Lines segment (which represents 60.4% of our consolidated gross written premiums in the nine months ended September 30, 2022) decreased 5.9% and increased 10.2% from the corresponding three and nine month periods in the prior year. The decline for the comparable three month periods was driven by discrete actions taken on renewal business that did not meet our risk appetite. Total policy submissions for Core E&S lines (excluding commercial auto) declined 4.9% from the prior year to date, but renewal submissions increased 14.0% and our ratio of bound policies to quoted policies improved generating 1.7% more bound policies in the nine months ended September 30, 2022 than in the nine months ended September 30, 2021. The total number of policies in force for the segment increased 7.3% over the prior year. Renewal rates for the Excess and Surplus Lines segment were up 10.9% compared to the nine months ended September 30, 2021. The change in gross written premiums compared to the same period in 2021 was notable in several divisions as shown below:

The components of gross written premiums for the Specialty Admitted Insurance segment (which represents 33.5% of our consolidated gross written premiums for the nine months ended September 30, 2022) are as follows:

	Three Months Ended September 30,				%		Nine Months Ended September 30,				%
	2022		2021		Change		2022		2021		Change
	($ in thousands)
Individual risk workers’ compensation premium	$	12,344	$	13,461	(8.3)	%	$	39,833	$	43,897	(9.3)	%
Fronting and program premium	111,045		107,714		3.1	%	334,233		333,503		0.2	%
Specialty Admitted gross written premium	$	123,389	$	121,175	1.8	%	$	374,066	$	377,400	(0.9)	%

Individual risk workers' compensation premium declined for the comparable three and nine month periods reflecting the soft market conditions currently present for workers' compensation. Our fronting written premium increased slightly from the prior year driven by new fronting relationships in the current year and the continued expansion of existing fronting relationships (together representing increases of $13.0 million or 19.2% and $41.8 million or 20.1% for the three and nine months ended September 30, 2022, respectively), and partially offset by the loss of one relationship from merger and acquisition activity at a general agent and a decline in written premium for our largest fronting relationship. Gross written premium for our largest fronting relationship declined from $30.7 million and $94.9 million for the three and nine months ended September 30, 2021, respectively, to $30.0 million and $84.8 million for the three and nine months ended September 30, 2022, respectively, reflecting a very competitive market for workers' compensation in California. Our largest fronting relationship represented 22.7% of the segment's gross written premium in the nine months ended September 30, 2022 down from 25.2% in the nine months ended September 30, 2021.

Gross written premiums for the Casualty Reinsurance segment (which represents 6.1% of our consolidated gross written premiums in the first nine months of 2022) increased $22.6 million over the corresponding three month period in the prior year primarily driven by premium adjustments and a timing difference with one renewal and extension. For the comparable nine month periods, gross written premiums decreased $41.2 million or 37.6% reflecting our current strategic focus on downsizing the Casualty Reinsurance third party book, which has resulted in the nonrenewal of several treaties in the current year and lower participations on certain renewing treaties. The Casualty Reinsurance segment generally writes large casualty-focused treaties that are expected to have lower volatility relative to property and catastrophe treaties. We rarely write stand-alone property reinsurance. When treaties that include property exposure are written, we utilize property occurrence caps, inuring reinsurance protection and low individual risk limits to minimize exposure.

Net Retention

Our net premium retention is summarized by segment as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Excess and Surplus Lines	68.8	%	58.7	%	64.0	%	60.6	%
Specialty Admitted Insurance	15.3	%	18.6	%	15.4	%	17.5	%
Casualty Reinsurance	100.0	%	100.0	%	103.2	%	81.1	%
Total	53.1	%	45.6	%	50.2	%	47.9	%

The net premium retention for the Excess and Surplus Lines segment increased relative to the three and nine month periods of the prior year. The segment's Excess Casualty division, which comprises approximately one-third of the segment's gross written premiums in the nine months ended September 30, 2022 and 2021, cedes a high percentage of written premiums under a reinsurance treaty and changes in growth rates of this division can impact comparable premium retention ratios for the segment. Effective with the current quarter, we increased our retention on the reinsurance treaty applicable to the Excess Casualty division. Net retention for the Excess Casualty division was 27.8% and 14.6% for the comparable three month periods, and 17.9% and 14.3% for the respective nine month periods. Net retention in the prior year was impacted by the aforementioned $8.1 million of reinstatement premium in the prior year third quarter which reduced net written premium and the net retention for the prior year quarter and year to date.

The net premium retention for the Specialty Admitted Insurance segment decreased for the three and nine months ended September 30, 2022 as compared to the prior year periods primarily due to a lower retention in the fronting business reflecting the mix of business and changes in reinsurance coverage as treaties renew. The net retention on the segment’s fronting business was 13.8% and 13.6% for the three and nine months ended September 30, 2022, respectively, compared to 17.7% and 16.3%

41

for the three and nine months ended September 30, 2021, respectively. The net retention on the individual risk workers’ compensation business was 29.6% and 29.9% for the three and nine months ended September 30, 2022, respectively, compared to 25.7% and 27.1% for the three and nine months ended September 30, 2021. The renewal of the workers' compensation quota share treaty on January 1, 2022 resulted in a higher retention for this business.

The Casualty Reinsurance segment previously wrote a retrocessional treaty/fronting arrangement under which 100% of the premiums were ceded. The treaty was nonrenewed for 2022 and net retentions above 100% in the current year reflect adjustments to prior year assumed and ceded written premiums on the treaty.

The Excess and Surplus Lines segment produced an underwriting profit of $16.4 million and combined ratio of 88.2% in the three months ended September 30, 2022 compared to an underwriting loss of $21.5 million and a combined ratio of 118.0% in the three months ended September 30, 2021. The loss ratio improvement from 97.9% in the prior year to 69.3% in the current year was primarily driven by net reserve development on prior accident years which was $139,000 adverse (excluding adverse prior year development on the legacy Rasier business and the impact of retroactive reinsurance - see Commercial Auto Loss Portfolio Transfer) for the three months ended September 30, 2022 compared to $29.5 million or 24.7 percentage points of net adverse development in the three months ended September 30, 2021. The net adverse development in the prior year included $29.6 million recognized with the loss portfolio transfer transaction with Aleka that was effective July 1, 2021.

For the nine months ended September 30, 2022, the segment produced an underwriting profit of $60.2 million and a combined ratio of 85.3%. This compares to an underwriting loss of $145.6 million and a combined ratio of 141.4% for the nine

42

months ended September 30, 2021. The loss ratio of 66.2% for the nine months ended September 30, 2022 includes $48,000 of net adverse reserve development (excluding adverse prior year development on the legacy Rasier business and the impact of retroactive reinsurance - see Commercial Auto Loss Portfolio Transfer) in our loss estimates for prior accident years. The loss ratio of 122.0% for the nine months ended September 30, 2021 includes $190.7 million of net adverse reserve development (54.3 percentage points) in our loss estimates for prior accident years, including $200.1 million of net adverse reserve development on our commercial auto business that was almost entirely related to a previously canceled account that has been in runoff since 2019. The reported losses on this terminated commercial auto account meaningfully exceeded our expectations in the three months ended March 31, 2021. We had expected that reported losses would decline as the account moved further into runoff, but the continued heavy reported loss emergence in the first quarter of 2021 indicated more inherent severity than anticipated. In response, we meaningfully adjusted our actuarial methodology, resulting in a significant strengthening of reserves for this account.

Attractive market conditions for our Excess and Surplus Lines segment have enabled us to grow earned premiums. Net earned premiums of the Excess and Surplus Lines segment were up 16.1% and 16.2% over the corresponding three and nine month periods in the prior year, respectively, including growth in lines that have meaningful ceding commissions. The expense ratios for the Excess and Surplus Lines segment were 18.9% and 19.1% for the three and nine months ended September 30, 2022, respectively, compared to 20.1% and 19.4% for the three and nine months ended September 30, 2021.

Underwriting results in both three month and nine month periods include hurricane catastrophe losses in our Excess Property book. The Excess and Surplus Lines segment has a surplus share reinsurance treaty in effect that was specifically designed to cover property risks. The surplus share treaty along with facultative reinsurance helps ensure that our net retained limit per risk will be $5.0 million or less. In the three months ended September 30, 2022, the Company recorded $5.0 million of net catastrophe losses for Hurricane Ian. In the three months ended September 30, 2021, the Company recorded $5.0 million of net catastrophe losses for Hurricane Ida.

Underwriting results in the prior year were also negatively impacted by $8.1 million of reinstatement premium, including $6.4 million triggered by one claim on a 2019 excess of loss treaty in the Excess and Surplus Lines segment. The reinstatement premium reduced net written and net earned premium in the prior year quarter and year to date and increased the underwriting loss.

The Specialty Admitted Insurance segment generated underwriting profits of $285,000 and $3.1 million (combined ratios of 98.4% and 84.3%) in the three months ended September 30, 2022 and 2021, respectively. The loss ratios of 86.3% and 77.5% include $1.3 million and $500,000 (7.1 and 2.5 percentage points), respectively, of net favorable development in our loss estimates for prior accident years. The impact of the higher net favorable reserve development in the current year was offset by a higher current accident year loss ratio (93.4% compared to 80.0% in the prior year) which reflects current actuarial indications and higher loss trends in the business.

43

For the nine months ended September 30, 2022 and 2021, the segment produced underwriting profits of $1.7 million and $6.5 million (combined ratios of 96.8% and 88.1%), respectively. The loss ratios of 79.6% and 72.0% include $2.8 million and $2.5 million (5.0 and 4.6 percentage points), respectively, of net favorable development in our loss estimates for prior accident years reflecting lower loss emergence in the workers’ compensation book compared to expectations. The higher current accident year loss ratio (84.6% compared to 76.6% in the prior year) was the biggest driver of the higher overall loss ratio, and consistent with the three months ended September 30, 2022, reflects current actuarial indications and higher loss trends in the business.

The expense ratio of the Specialty Admitted Insurance segment was 12.1% and 17.2% for the three and nine months ended September 30, 2022, respectively, compared to the prior year ratios of 6.8% and 16.1%, respectively. The segment benefited from adjustments in the prior year to the allowance for doubtful accounts, premium taxes, and assessments which together represented a 9.9 and 3.6 percentage point decrease in the segment expense ratio for the prior year quarter and year to date, respectively. Fee income in the current year increased 5.5% and 7.3% over the respective three and nine month periods in the prior year due to the growth in our fronting business. The impact of reinstatement premiums and other adjustments to tax and assessment accruals in the current quarter together represented a 6.8 and 2.4 percentage point decrease in the segment expense ratio for the current quarter and year to date, respectively.

The Casualty Reinsurance segment produced an underwriting profit of $3.0 million and a combined ratio of 90.9% for the three months ended September 30, 2022 compared to an underwriting loss of $11.9 million and a combined ratio of 138.2% for the three months ended September 30, 2021. The loss ratio improved from 107.9% in the prior three month period to 61.6% in the current year, driven mainly by the impact of $15.1 million or 48.4 percentage points of net adverse development in our loss estimates for prior accident years in the three months ended September 30, 2021. As outlined in the “Strategic Actions” above, on February 23, 2022, JRG Re entered into the Retrocession Agreement to reinsure the majority of the Casualty Reinsurance segment's reserves. No prior accident year reserve development was recognized for this segment in the three months ended September 30, 2022.

For the nine months ended September 30, 2022 and 2021, the segment had underwriting losses of $3.7 million and $16.9 million (combined ratios of 103.6% and 117.2%), respectively. The loss ratio of 72.7% for the nine months ended September 30, 2022 includes losses of $11.5 million or 11.2 points (including $6.8 million or 6.6 points of net adverse reserve development on prior accident years and $4.7 million of current accident year losses) recognized in the three months ended March 31, 2022 associated with the Retrocession Agreement. The loss ratio of 83.5% for the nine months ended September 30, 2021 includes $22.6 million or 23.1 percentage points of net adverse development in our loss estimates for prior accident years. The higher year to date current accident year loss ratio (66.1% for the nine months ended September 30, 2022 compared to 60.4% in the prior year period) primarily reflects the $4.7 million or 4.6 points of current accident year losses associated with the Retrocession Agreement and changes in the mix of business.

The Casualty Reinsurance segment focuses on proportional reinsurance which requires larger ceding commissions resulting in a higher commission expense than in our other segments. The expense ratios of the Casualty Reinsurance segment were

44

29.3% and 30.9% for the three and nine months ended September 30, 2022, respectively, compared to 30.3% and 33.7% in the corresponding prior year periods. The lower current year expense ratios reflects higher net earned premiums (increases of 6.8% and 5.0% versus the corresponding three and nine month prior year periods) and lower commissions due to the mix of business and commission slides which decreased the expense ratio by 4.4 and 2.4 points in the three and nine months ended September 30, 2022, respectively, compared to a decrease of 2.5 and an increase of 0.6 points in the three and nine months ended September 30, 2021. General and administrative expenses were also lower for the three and nine months ended September 30, 2022 driven primarily by lower compensation and related expenses.

Corporate and Other Segment

Other operating expenses for the Corporate and Other segment include personnel costs associated with the Bermuda and U.S. holding companies, professional fees, and various other corporate expenses that were not reimbursed by our subsidiaries, including costs associated with our internal quota share, rating agencies and strategic initiatives. The expenses are included in our calculation of consolidated underwriting profit, and in our consolidated expense ratio and combined ratio.

Total operating expenses of the Corporate and Other segment were $8.4 million and $25.2 million for the three and nine months ended September 30, 2022, respectively, compared to $7.3 million and $23.3 million for the three and nine months ended September 30, 2021. The higher current year expenses as compared to the respective three and nine month periods in the prior year were largely driven by higher compensation expenses due to the hiring of additional employees.

Investing Results

Net investment income was $17.3 million and $48.3 million for the three and nine months ended September 30, 2022, respectively, compared to $15.3 million and $44.7 million for the same periods in the prior year. The Company's private investments generated losses of $424,000 and income of $2.0 million for the three and nine months ended September 30, 2022, respectively, compared to income of $1.8 million and $2.9 million in the respective prior year periods. Excluding private investments, our net investment income for the three and nine months ended September 30, 2022 increased 31.1% and 10.8% from the prior year, respectively, principally due to higher yields on fixed maturities and bank loan participations. The average duration of our portfolio excluding restricted cash equivalents was 4.2 years at September 30, 2022.

Major categories of the Company’s net investment income are summarized as follows:

The following table summarizes our annualized gross investment returns:

	2022		2021		2022		2021

Of our total cash and invested assets of $2,363.6 million at September 30, 2022 (excluding restricted cash equivalents), $187.5 million represents the cash and cash equivalents portion of the portfolio. The majority of the portfolio, or $1,639.2

45

million, is comprised of fixed maturity securities that are classified as available-for-sale and carried at fair value with unrealized gains and losses on these securities reported, net of applicable taxes, as a separate component of accumulated comprehensive (loss) income. In the nine months ended September 30, 2022, the fair values of our fixed maturity securities were negatively impacted by a heightened inflationary environment and rate actions of the Federal Reserve, which led to higher interest rates and lower fair values of our fixed maturity securities. Unrealized losses on fixed maturities recognized in other comprehensive (loss) income resulted in a $205.2 million reduction in accumulated other comprehensive (loss) income in the nine months ended September 30, 2022.

Also included in our investments are $160.3 million of bank loan participations, $118.1 million of equity securities, $208.9 million of short-term investments, and $49.5 million of other invested assets.

Bank loan participations generally provide a higher yield than our portfolio of fixed maturity securities and are primarily senior, secured floating-rate debt rated “BB”, “B”, or “CCC” by Standard & Poor’s or an equivalent rating from another nationally recognized statistical rating organization, and are therefore below investment grade. Bank loans include assignments of and participations in performing and non-performing senior corporate debt generally acquired through primary bank syndications and in secondary markets. They consist of, but are not limited to, term loans, the funded and unfunded portions of revolving credit facilities, and similar loans and investments. Bank loan participations are measured at fair value pursuant to the Company's election of the fair value option, and changes in unrealized gains and losses in bank loan participations are reported in our income statement as net realized and unrealized gains (losses) on investments. At September 30, 2022 and December 31, 2021, the fair market value of these securities was $160.3 million and $156.0 million, respectively.

For the nine months ended September 30, 2022, the Company recognized net realized and unrealized investment losses of $29.9 million ($7.8 million of net realized and unrealized investment losses for the three months ended September 30, 2022), including $13.8 million of net unrealized losses on bank loan participations, $16.0 million of net unrealized losses for the change in the fair value of equity securities, $284,000 of net realized investment gains on the sale of fixed maturity securities, $376,000 of net realized investment losses on the sale of bank loan participations, and $47,000 of net realized investment gains on the sale of equity securities.

For the nine months ended September 30, 2021, the Company recognized net realized and unrealized investment gains of $13.7 million ($4.0 million of net realized and unrealized investment gains for the three months ended September 30, 2021), including $6.6 million of net unrealized gains on bank loan participations, $3.8 million of net unrealized gains for the change in the fair value of equity securities, $4.3 million of net realized investment gains on the sale of fixed maturity securities, $645,000 of net realized investment losses on the sale of bank loan participations, and $386,000 of net realized investment losses on the sale of equity securities.

In conjunction with its outside investment managers, the Company performs quarterly reviews of all securities within its investment portfolio to determine whether any impairment has occurred. Management concluded that none of its fixed maturity securities were impaired at September 30, 2022 or December 31, 2021. At September 30, 2022, 99.8% of the Company’s fixed maturity security portfolio was rated “BBB-” or better (“investment grade”) by Standard & Poor’s or received an equivalent rating from another nationally recognized rating agency. Management does not intend to sell available-for-sale securities in an unrealized loss position, and it is not “more likely than not” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs.

Other Income and Expense

Other income and expense primarily consists of non-operating income of $247,000 and non-operating expenses of $100,000 for the three and nine months ended September 30, 2022, respectively, and non-operating expenses of $625,000 and $2.0 million for the three and nine months ended September 30, 2021, respectively. The non-operating income for the three months ended September 30, 2022 includes a $430,000 broker fee rebate associated with the Retrocession Agreement in the Casualty Reinsurance segment. Non-operating expenses include legal fees related to a purported class action lawsuit, legal and other professional fees related to the Company's May 2021 common share offering and various strategic initiatives, and employee severance costs.

Interest Expense

Interest expense was $5.0 million and $2.2 million for the three months ended September 30, 2022 and 2021, respectively ($11.3 million and $6.7 million for the nine months ended September 30, 2022 and 2021, respectively). Interest expense for the three months and nine months ended September 30, 2022 includes $1.2 million and $2.6 million of crediting fees on the Funds Withheld Account balance under the Retrocession Agreement. The impact of rising interest rates on our variable rate senior and trust preferred debt also contributed to the higher current year interest expense. See “—Liquidity and Capital Resources—Sources and Uses of Funds” for more information regarding our senior bank debt facilities and trust preferred securities.

Amortization of Intangibles

The Company recorded $90,000 of amortization of intangible assets in each of the three months ended September 30, 2022 and 2021 ($272,000 in each of the nine months ended September 30, 2022 and 2021).

Income Tax Expense

Our effective tax rate fluctuates from period to period based on the relative mix of income reported by country and the respective tax rates imposed by each tax jurisdiction. For U.S.-sourced income, the Company’s U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate to income before taxes due primarily to interest income on tax-advantaged state and municipal securities, dividends received income, and excess tax benefits on share based compensation. For the nine months ended September 30, 2022, our effective tax rate was 30.9%. The effective rate exceeded the 21.0% U.S. statutory rate due to a projected annual loss in Bermuda that does not provide a tax benefit and certain discreet items including excess tax expenses associated with vested restricted share units (“RSUs”) in the nine months ended September 30, 2022. The Company had a pre-tax loss of $129.6 million for the nine months ended September 30, 2021 and recorded a U.S. federal income tax benefit of $23.1 million. The pre-tax loss was largely driven by the $210.8 million of net adverse reserve development on prior accident years, including $190.7 million of net adverse development from the Excess and Surplus Lines segment that was primarily related to a former commercial auto account. For the nine months ended September 30, 2021, our U.S. federal income tax benefit was 17.8% of the loss before taxes.

Reserves

An indicator of reserve strength that we monitor closely is the percentage of our gross and net loss reserves that are comprised of incurred but not reported (“IBNR”) reserves.

The Company’s gross reserve for losses and loss adjustment expenses at September 30, 2022 was $2,786.7 million. Of this amount, 61.0% relates to amounts that are IBNR. This amount was 59.6% at December 31, 2021. The Company’s gross reserves for losses and loss adjustment expenses by segment are summarized as follows:

	Gross Reserves at September 30, 2022
	Case		IBNR		Total
	($ in thousands)
Excess and Surplus Lines	$	607,079	$	1,015,398	$	1,622,477
Specialty Admitted Insurance	337,642		400,085		737,727
Casualty Reinsurance	141,184		285,312		426,496
Total	$	1,085,905	$	1,700,795	$	2,786,700

At September 30, 2022, the amount of net reserves (prior to the $621,000 allowance for uncollectible reinsurance recoverables) of $1,201.2 million that related to IBNR was 64.8%. This amount was 64.4% at December 31, 2021. The Company’s net reserves for losses and loss adjustment expenses by segment are summarized as follows:

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Funds

Our sources of funds consist primarily of premiums written, investment income, reinsurance recoveries, proceeds from sales and redemptions of investments, borrowings on our credit facilities, and the issuance of common and Series A Preferred Shares. We use operating cash flows primarily to pay operating expenses, losses and loss adjustment expenses, reinsurance premiums, and income taxes. Cash flow from operations may differ substantially from net income. The potential for a large claim under an insurance or reinsurance contract means that substantial and unpredictable payments may need to be made within relatively short periods of time.

The following table summarizes our cash flows:

	Nine Months Ended September 30,
	2022		2021
	($ in thousands)
Cash and cash equivalents provided by (used in):
Operating activities (excluding restricted cash equivalents)	$	167,649	$	(211,394)
Investing activities	(262,181)		111,759
Financing activities	91,953		157,926
Change in cash and cash equivalents	(2,579)		58,291
Change in restricted cash equivalents (operating activities)	480		(849,920)
Change in cash, cash equivalents, and restricted cash equivalents	$	(2,099)	$	(791,629)

Cash provided by operating activities excluding restricted cash equivalents of $167.6 million for the nine months ended September 30, 2022 was driven by the growth in our U.S. segments and the collection of premiums receivable at a quicker rate than payments of loss and loss adjustment expenses. Cash used in operating activities excluding restricted cash equivalents of $211.4 million for the nine months ended September 30, 2021 primarily reflects the outflow of funds to effect the Commercial Auto LPT in the third quarter.

Cash used in investing activities of $262.2 million for the nine months ended September 30, 2022 reflects our efforts to enhance the yield in our investment portfolio by investing available cash and cash equivalents into higher yielding investments. Cash provided by investing activities of $111.8 million for the nine months ended September 30, 2021 was primarily due to the investments sold/funds withdrawn from our investment portfolio to effect the Commercial Auto LPT in the third quarter. Cash and cash equivalents (excluding restricted cash equivalents) comprised 7.9% and 9.7% of total cash and invested assets at September 30, 2022 and 2021, respectively.

Cash provided by financing activities of $92.0 million for the nine months ended September 30, 2022 includes $144.9 million of net proceeds (after expenses) from the issuance and sale of 150,000 Series A Preferred Shares on March 1, 2022. The proceeds were used for general corporate purposes and to repay $40.0 million of loans outstanding on the 2017 Facility (as defined below) on March 28, 2022. Financing activities for the nine months ended September 30, 2022 also include $5.9 million of dividends paid to common shareholders and $6.1 million of dividends paid on the Series A Preferred Shares.

 Cash provided by financing activities of $157.9 million for the nine months ended September 30, 2021 includes $192.1 million of net proceeds (before expenses) from a public offering of our common shares that closed on May 10, 2021. The proceeds were used for general corporate purposes. Financing activities for the nine months ended September 30, 2021 also includes $32.0 million of dividends paid to common shareholders.

The change in restricted cash equivalents for the nine months ended September 30, 2021 primarily reflects restricted cash equivalents returned to a former insured, per the terms of a collateral trust. See Amounts Recoverable from an Indemnifying Party and Reinsurer on Legacy Commercial Auto Book below.

Dividends

We are organized as a Bermuda holding company with our operations conducted by our wholly-owned subsidiaries. Accordingly, our holding company may receive cash through loans from banks, issuance of equity and debt securities, corporate service fees or dividends received from our subsidiaries and/or other transactions. Our U.S. holding company may receive cash in a similar manner and also through payments from our subsidiaries pursuant to our U.S. consolidated tax allocation agreement.

The payment of dividends by our subsidiaries to us is limited by statute. In general, the laws and regulations applicable to our domestic insurance subsidiaries limit the aggregate amount of dividends or other distributions that they may declare or pay within any 12-month period without advance regulatory approval. Generally, the limitations are based on the greater of statutory net income for the preceding year or 10.0% of statutory surplus at the end of the preceding year. In addition, insurance regulators have broad powers to prevent reduction of statutory surplus to inadequate levels and could refuse to permit the payment of dividends calculated under any applicable formula. See Item 1— “Business Regulation—U.S. Insurance Regulation—State Regulation” in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 1, 2022 for additional information. The maximum amount of dividends available to the U.S. holding company from our U.S. insurance subsidiaries during 2022 without regulatory approval is $27.2 million.

The Bermuda Insurance Act of 1978 prohibits an insurer 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. An insurer can declare or pay dividends without prior regulatory approval up to 25% of the total statutory capital and surplus (as shown on its previous financial year's statutory balance sheet). See Item 1- “Business Regulation- Bermuda Insurance Regulation- Restrictions on Dividends and Distributions” in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 1, 2022 for additional information. Based on that calculation, the maximum combined amount of dividends and return of capital available to us from our Bermuda insurers without regulatory approval in 2022 is calculated to be approximately $129.7 million. However, any dividend payment is contingent upon continued compliance with Bermuda regulatory requirements, including but not limited to the enhanced solvency requirement calculations.

Holders of the Series A Preferred Shares are entitled to a dividend at the initial rate of 7% of the Liquidation Preference per annum, paid in cash, in-kind in common shares or in Series A Preferred Shares, at our election. On the five-year anniversary of the Closing Date, and each five-year anniversary thereafter, the dividend rate will reset to a rate equal to the five-year U.S. treasury rate plus 5.2%. Dividends accrue quarterly and are payable on March 31, June 30, September 30 and December 31 of each year. Cash dividends of $6.1 million have been paid on the Series A Preferred Shares from the date the Series A Preferred Shares were issued (March 1, 2022) through September 30, 2022.

At September 30, 2022, the Bermuda holding company had $2.0 million of cash and cash equivalents. The U.S. holding company had $18.9 million of cash and invested assets, comprised of cash and cash equivalents of $5.0 million, short-term investments of $7.0 million, and other invested assets of $6.9 million, which are not subject to regulatory restrictions. Additionally, our U.K. intermediate holding company had no invested assets and cash of less than ten thousand dollars at September 30, 2022.

Credit Agreements

The Company has a $315.0 million senior revolving credit facility (as amended or amended and restated, the “2013 Facility”). The 2013 Facility is comprised of the following at September 30, 2022:

•A $102.5 million secured revolving facility used by JRG Re to issue letters of credit for the benefit of third-party reinsureds. This portion of our credit facility is secured by our investment securities. At September 30, 2022, the Company had $40.5 million of letters of credit issued under the secured facility.

•A $212.5 million unsecured revolving facility to meet the working capital needs of the Company. All unpaid principal on the revolver is due at maturity. Interest accrues quarterly and is payable in arrears at 3-month LIBOR plus a margin which is currently 1.5% and is subject to change according to terms in the credit agreement. At September 30, 2022, the Company had a drawn balance of $185.8 million outstanding on the unsecured revolver.

The 2013 Facility has been amended from time to time since its inception in 2013. On November 8, 2019, the Company entered into a Second Amended and Restated Credit Agreement for the 2013 Facility which, among other things, extended the maturity date of the 2013 Facility until November 8, 2024, increased the amount available under the unsecured revolving credit facility to $212.5 million, lowered the applicable interest rate and letter of credit fees, and modified certain negative covenants to be less restrictive.

50

The 2013 Facility contains certain financial and other covenants (including minimum net worth, maximum ratio of total adjusted debt outstanding to total capitalization, and financial strength ratings) with which the Company was in compliance at September 30, 2022.

On August 2, 2017, the Company, and its wholly-owned subsidiary, JRG Re, together as borrowers, entered into a credit agreement (the "2017 Facility") that provides the Company with a revolving line of credit of up to $100.0 million, which may be used for loans and letters of credit made or issued, at the borrowers' option, on a secured or unsecured basis. Obligations under the 2017 Facility carry a variable rate of interest subject to terms in the credit agreement and will mature 30 days after notice of termination from the lender. The 2017 Facility contains certain financial and other covenants with which we are in compliance at September 30, 2022. The loans and letters of credit made or issued under the revolving line of credit of the 2017 Facility may be used to finance the borrowers' general corporate purposes. The 2017 Facility has been amended from time to time since its inception in 2017, including on November 8, 2019 when the Company entered into a First Amendment to Credit Agreement which, among other things, lowered the applicable interest rate and modified certain negative covenants to be less restrictive. Interest accrues quarterly and is payable in arrears at variable rates which are subject to change according to terms in the credit agreement. At September 30, 2022, unsecured loans of $21.5 million and secured letters of credit totaling $22.6 million were outstanding on the 2017 Facility. During the three months ended March 31, 2022, the Company repaid $40.0 million of loans that were outstanding under the 2017 Facility.

On May 26, 2004, we issued $15.0 million of senior debt due April 29, 2034. The senior debt is not redeemable by the holder or subject to sinking fund requirements. Interest accrues quarterly and is payable in arrears at a floating rate per annum equal to the 3-month LIBOR plus 3.85%. This senior debt is redeemable at par prior to its stated maturity at our option in whole or in part. The terms of the senior debt contain certain covenants, with which we are in compliance at September 30, 2022, and which, among other things, restrict our ability to assume senior indebtedness secured by our U.S. holding company’s common stock or its subsidiaries’ capital stock or to issue shares of its subsidiaries’ capital stock.

From May 2004 through January 2008, we sold trust preferred securities through five Delaware statutory trusts sponsored and wholly-owned by the Company or its subsidiaries. Each trust used the net proceeds from the sale of its trust preferred securities to purchase our floating-rate junior subordinated debt.

The following table summarizes the nature and terms of the junior subordinated debt and trust preferred securities outstanding at September 30, 2022 (including the Company’s repurchases of a portion of these trust preferred securities):

All of the junior subordinated debt is currently redeemable at 100.0% of the unpaid principal amount at our option.

The junior subordinated debt contains certain covenants with which we are in compliance as of September 30, 2022.

At September 30, 2022 and December 31, 2021, the Company's leverage ratio was 22.8% and 31.1%, respectively. The leverage ratio is defined in our senior credit agreements as the ratio of adjusted consolidated debt to total capital. Adjusted consolidated debt treats trust preferred securities as equity capital up to 15% of total capital. The Series A Preferred Shares represent equity capital for purposes of the leverage ratio calculation under the credit agreements. Total capital is defined as total debt plus tangible equity excluding accumulated other comprehensive income. The maximum leverage ratio permitted by the agreements is 35.0%. We believe having debt as part of our capital structure allows us to generate a higher return on equity and greater book value per share results than we could by using equity capital alone.

Ceded Reinsurance

Our insurance segments enter into reinsurance contracts to limit our exposure to potential losses arising from large risks, to protect against the aggregation of several risks in a common loss occurrence, and to provide additional capacity for growth. Our reinsurance is contracted under excess of loss and quota share reinsurance contracts. In excess of loss reinsurance, the reinsurer agrees to assume all or a portion of the ceding company’s losses in excess of a specified amount. The premiums payable to the reinsurer are negotiated by the parties based on their assessment of the amount of risk being ceded to the reinsurer because the reinsurer does not share proportionately in the ceding company’s losses. In quota share reinsurance, the reinsurer agrees to assume a specified percentage of the ceding company’s losses arising out of a defined class of business in exchange for a corresponding percentage of premiums. For the three months ended September 30, 2022 and 2021, our net premium retention was 53.1% and 45.6%, respectively.

The following is a summary of our Excess and Surplus Lines segment’s net retention after reinsurance as of September 30, 2022:

Line of Business	Company Retention
Casualty
Primary Specialty Casualty, including Professional Liability	Up to $1.0 million per occurrence, subject to a $1.0 million aggregate deductible.(1)
Primary Casualty	Up to $2.0 million per occurrence.(2)
Excess Casualty	Up to $2.0 million per occurrence.(3)
Property	Up to $5.0 million per event.(4)

(1)    Except for Life Sciences quota share carve out, which is up to $2.0 million per occurrence.

(2)    Total exposure to any one claim is generally $1.0 million.

(3)    For policies with an occurrence limit up to $10.0 million, the excess casualty treaty is set such that our retention is no more than $2.0 million.

(4)    The property catastrophe reinsurance treaty has a limit of $55.0 million with one reinstatement.

We use catastrophe modeling software to analyze the risk of severe losses from hurricanes and earthquakes on our exposure. We utilize the model in our risk selection, pricing, and to manage our overall portfolio probable maximum loss (“PML”) accumulations. A PML is an estimate of the amount we would expect to pay in any one catastrophe event within a given annual probability of occurrence (i.e. a return period or loss exceedance probability).

In our Excess and Surplus Lines segment, we write a small book of excess property insurance, but we do not write primary property insurance. The Excess and Surplus Lines segment has a surplus share reinsurance treaty in effect that was specifically designed to cover property risks. The surplus share treaty along with facultative reinsurance helps ensure that our net retained limit per risk will be $5.0 million or less.

Based upon the modeling of our Excess and Surplus Lines and Specialty Admitted segments, it would take an event at the 1 in 1000 year PML to exhaust our $60.0 million property catastrophe reinsurance. In the event of a catastrophe loss exhausting our $60.0 million property catastrophe reinsurance, we estimate our pre-tax cost would not exceed 2.5% of shareholders’ equity, including reinstatement premiums and net retentions. In addition to this retention, we would retain any losses in excess of our reinsurance coverage limits.

On September 27, 2021, James River entered into the Commercial Auto LPT with Aleka to reinsure substantially all of the Excess and Surplus Lines segment’s legacy portfolio of commercial auto policies previously issued to Rasier. See “Amounts Recoverable from an Indemnifying Party and Reinsurer on the Legacy Commercial Auto Book” below for further information on this reinsurance agreement.

The following is a summary of our Specialty Admitted Insurance segment’s ceded reinsurance in place as of September 30, 2022:

Line of Business	Coverage
Casualty
Workers’ Compensation	Quota share coverage for 65.5% of the first $1.0 million.(1)(2) Excess of loss coverage for $29.0 million in excess of $1.0 million.(1)(2)
Auto Programs	Quota share coverage for 70-90% of limits up to $1.5 million liability and $7.5 million physical damage per occurrence.
General Liability & Professional Liability – Programs	Quota share coverage for 65%-100% of limits up to $3.0 million per occurrence.
Umbrella and Excess Casualty - Programs	Quota share coverage for at least 65% of limits up to $10.0 million per occurrence, and 75% of excess of loss coverage for $5.0 million in excess of $10.0 million.
Property
Property within Package - Programs	Quota share coverage for 100% of limits up to $40.0 million per occurrence.
Excess Property	Quota share coverage for 100% of limits up to $16.9 million.
Catastrophe Coverage	Excess of Loss coverage for $59.0 million in excess of $1.0 million per occurrence.
Aviation Programs	Quota share coverage for 80% of limits up to $20 million liability and $2.5 million hull per occurrence, each aircraft; and excess of loss coverage for up to $8.7M excess of $300 thousand of our 20% share of the quota share each occurrence.

(1)    Excluding one program which has quota share coverage for 84% of the first $1.0 million per occurrence and excess of loss coverage for $49.0 million in excess of $1.0 million per occurrence.

(2)    Includes any residual market pools.

Our Specialty Admitted Insurance segment purchases reinsurance for at least 50% of the exposed limits on specialty admitted property-casualty business. The segment enters into reinsurance contracts for the individual risk workers’ compensation business as well as fronting and program business. While the segment focuses on casualty business, incidental property risk is incurred in the fronting and program business. The segment is covered for $59.0 million in excess of $1.0 million per occurrence to manage its property exposure to an approximate 1 in 1,000 year PML.

In our Casualty Reinsurance segment, we also have limited property catastrophe exposure on treaties in run-off, primarily through auto physical damage coverage. In the aggregate, we believe our pre-tax group-wide PML from a 1 in 1,000 year property catastrophe event would not exceed 2.5% of shareholders’ equity, inclusive of reinstatement premiums payable.

On February 23, 2022, JRG Re entered into the Retrocession Agreement with FRL to reinsure the majority of the segment risk, which closed on March 31, 2022. See “Strategic Actions – Loss Portfolio Transfer Retrocession Agreement” above for further information on this retrocession agreement.

We also had a contingency clash reinsurance treaty to cover both the Excess and Surplus Lines and Specialty Admitted Insurance segments in the event of a claim incident involving more than one of our insureds in addition to Extra Contractual and Excess Policy Limits protection. The treaty covered $10.0 million in excess of a $2.0 million retention for loss occurrences within the treaty term. This coverage was put into runoff effective July 1, 2022. As of September 30, 2022, our average net retained limit per risk is $2.5 million.

Effective January 1, 2020, we purchased an additional $10.0 million in claims made coverage for excess policy limits and extra contractual obligations exposures above the clash and contingency treaty for the period 2014 to present. This treaty has one reinstatement.

The Company’s insurance segments remain liable to policyholders if its reinsurers are unable to meet their contractual obligations under applicable reinsurance agreements. We establish an allowance for credit losses for our current estimate of uncollectible reinsurance recoverables. At September 30, 2022, the allowance for credit losses on reinsurance recoverables was $621,000. To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. The Company generally seeks to purchase reinsurance from reinsurers with A.M. Best financial strength ratings of “A-” (Excellent) or better. The Company’s reinsurance contracts generally require reinsurers that are not authorized as reinsurers under U.S. state insurance regulations or that experience rating downgrades from rating agencies below specified levels to fund their share of the Company’s ceded outstanding losses and loss adjustment expense reserves, typically through the use of irrevocable and unconditional letters of credit. In fronting arrangements, which the Company conducts through its Specialty Admitted Insurance segment, we are subject to credit risk

53

with regard to insurance companies who act as reinsurers for us in such arrangements. We customarily require a collateral trust arrangement to secure the obligations of the insurance entity for whom we are fronting.

At September 30, 2022, we had reinsurance recoverables on unpaid losses of $1,584.8 million (net of a $621,000 allowance for credit losses) and reinsurance recoverables on paid losses of $110.3 million, and all material recoverable amounts were from companies with A.M. Best ratings of “A-" (Excellent) or better, are collateralized by the reinsurer for our benefit through letters of credit or funds on deposit in trust accounts, or represent recoverables from a state residual market for automobile insurance.

Amounts Recoverable from an Indemnifying Party and Reinsurer on Legacy Commercial Auto Book

James River previously issued a set of commercial auto insurance contracts to Rasier (the “Rasier Commercial Auto Policies”) under which James River pays losses and loss adjustment expenses on the contracts. James River has indemnity agreements with Rasier (non-insurance entities) (collectively, the “Indemnity Agreements”) and is contractually entitled to reimbursement for the portion of the losses and loss adjustment expenses paid on behalf of Rasier under the Rasier Commercial Auto Policies and other expenses incurred by James River. On September 27, 2021, James River entered into a loss portfolio transfer reinsurance agreement (the “Commercial Auto LPT”) with Aleka to reinsure substantially all of the Rasier Commercial Auto Policies for which James River is not otherwise indemnified by Rasier under the Indemnity Agreements. Under the terms of the Commercial Auto LPT, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier Commercial Auto Policies written in the years 2013-2019, which amount constituted the reinsurance premium.

Each of Rasier and Aleka are required to post collateral under the Indemnity Agreements and the Commercial Auto LPT, respectively:

•Pursuant to the Indemnity Agreements, Rasier is required to post collateral equal to 102% of James River's estimate of the amounts that are recoverable or may be recoverable under the indemnity agreements, including, among other things, case loss and loss adjustment expense reserves, IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess policy limits liabilities. The collateral is provided through a collateral trust arrangement (the “Indemnity Trust”) in favor of James River by Aleka. In connection with the execution of the Commercial Auto LPT, James River returned $691.3 million to the Indemnity Trust, representing the remaining balance of the amount withdrawn in October 2019, as was permitted under the indemnification agreements with Rasier and the associated trust agreement. At September 30, 2022, the balance in the Indemnity Trust was $262.1 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Indemnity Agreements as described below, the total balance of collateral securing Rasier’s obligations under the Indemnity Agreements was $331.3 million.

•Pursuant to the Commercial Auto LPT, Aleka is required to post collateral equal to 102% of James River's estimate of Aleka's obligations under the Commercial Auto LPT, calculated in accordance with statutory accounting principles. The collateral is provided through a collateral trust arrangement (the “LPT Trust”) established in favor of James River by Aleka. At September 30, 2022, the balance in the LPT Trust was $118.3 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Commercial Auto LPT as described below, the total balance of collateral securing Aleka’s obligations under the Commercial Auto LPT was $146.5 million. At September 30, 2022, the total reinsurance recoverables under the Commercial Auto LPT was $189.1 million (including $174.3 million of unpaid recoverables and $14.8 million of paid recoverables).

In connection with the execution of the Commercial Auto LPT, James River and Aleka entered into an administrative services agreement (the “Administrative Services Agreement”) with a third party claims administrator (the “Administrator”) pursuant to which the Administrator handles the claims on the Rasier Commercial Auto Policies for the remaining life of those claims. The claims paid by the Administrator are reimbursable by James River, and pursuant to the Administrative Services Agreement, James River established a loss fund trust account for the benefit of the Administrator (the “Loss Fund Trust”) to collateralize its claims payment reimbursement obligations. James River funds the Loss Fund Trust using funds withdrawn from the Indemnity Trust, funds withdrawn from the LPT Trust, and its own funds, in each case in an amount equal to the pro rata portion of the required Loss Fund Trust balance attributable to the Indemnity Agreements, the Commercial Auto LPT and James River’s existing third party reinsurance agreements, respectively. At September 30, 2022, the balance in the Loss Fund Trust was $102.5 million, including $69.2 million representing collateral supporting Rasier’s obligations under the Indemnity Agreements and $28.2 million representing collateral supporting Aleka’s obligations under the Commercial Auto LPT. Funds posted to the Loss Fund Trust are classified as restricted cash equivalents on the Company's balance sheet.

While the Commercial Auto LPT brings economic finality to substantially all of the Rasier Commercial Auto Policies, the Company has credit exposure to Rasier and Aleka under the Indemnity Agreements and the Commercial Auto LPT if the estimated losses and expenses of the Rasier Commercial Auto Policies grow at a faster pace than the growth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and loss adjustment expenses and other amounts recoverable under the Indemnity Agreements and the Commercial Auto LPT, which are the basis for establishing the collateral balances, are lower than actual amounts paid or payable. The amount of our credit exposure in any of these instances could be

54

material. To mitigate these risks, we closely and frequently monitor our exposure compared to our collateral held, and we request additional collateral in accordance with the terms of the Commercial Auto LPT and Indemnity Agreements when our analysis indicates that we have uncollateralized exposure.

Ratings

The A.M. Best financial strength rating for our group’s regulated insurance and reinsurance subsidiaries is “A-” (Excellent) with a stable outlook. This rating reflects A.M. Best’s opinion of our insurance and reinsurance subsidiaries’ financial strength, operating performance and ability to meet obligations to policyholders and is not an evaluation directed towards the protection of investors. The rating for our operating insurance and reinsurance companies of “A-” (Excellent) is the fourth highest rating of the thirteen ratings issued by A.M. Best and is assigned to insurers that have, in A.M. Best’s opinion, an excellent ability to meet their ongoing obligations to policyholders. On March 4, 2021, A.M. Best announced that it reduced the outlook on our regulated insurance subsidiaries to negative from stable on the “A” (Excellent) financial strength rating on such entities following our announcement of $86.0 million of adverse development on reserves for losses and loss adjustment expenses in the fourth quarter of 2020 principally related to our commercial auto business in our Excess and Surplus Lines segment. On May 7, 2021, following the Company's announcement of $168.7 million of further adverse development in the first quarter of 2021 on reserves for losses and loss adjustment expenses in our Excess and Surplus Lines segment, inclusive of $170.0 million of unfavorable development in our commercial auto business, A.M. Best announced a downgrade of our financial strength rating to “A-” (Excellent) and maintained a negative outlook on our regulated insurance subsidiaries. The Company's outlook was upgraded to stable by A.M. Best in the third quarter of 2021 following the closing of the Commercial Auto LPT which reinsures substantially all of the legacy commercial auto business.

The financial strength ratings assigned by A.M. Best have an impact on the ability of our regulated subsidiaries to attract and retain agents and brokers and on the risk profiles of the submissions for insurance that our subsidiaries receive. We believe the “A-” (Excellent) ratings assigned to our insurance and reinsurance subsidiaries allow our subsidiaries to actively pursue relationships with the agents and brokers identified in their marketing plans.

Series A Preferred Shares

The Company closed on the issuance and sale of 150,000 Series A Preferred Shares on March 1, 2022 for an aggregate purchase price of $150.0 million, or $1,000 per share, in a private placement. The Series A Preferred Shares are convertible into the Company’s common shares at the option of the holder at any time, or at the Company’s option under certain circumstances. Dividends on the Series A Preferred Shares accrue quarterly at the initial rate of 7% of the Liquidation Preference per annum, which may be paid in cash, in-kind in common shares or in Series A Preferred Shares, at the Company’s election.

EQUITY

Total common shares outstanding increased from 37,373,066 at December 31, 2021 to 37,450,438 at September 30, 2022, reflecting 77,372 common shares issued in the nine months ended September 30, 2022 related to vesting of RSUs.

Share Based Compensation Expense

For the three months ended September 30, 2022 and 2021, the Company recognized $2.2 million and $1.5 million of share based compensation expense, respectively ($6.2 million and $5.2 million in the nine month periods ended September 30, 2022 and 2021, respectively). As of September 30, 2022, the Company had $13.5 million of unrecognized share based compensation expense expected to be charged to earnings over a weighted-average period of 2.0 years.

Underwriting Performance Ratios

The following table provides the underwriting performance ratios of the Company inclusive of the business subject to retroactive reinsurance accounting for loss portfolio transfers. There is no economic impact to the Company over the life of a loss portfolio transfer contract so long as any additional losses subject to the contract are within the limit of the loss portfolio transfer and the counterparty performs under the contract. Retroactive reinsurance accounting is not indicative of our current and ongoing operations. Management believes that providing loss ratios and combined ratios on business not subject to retroactive reinsurance accounting for loss portfolio transfers gives the users of our financial statements useful information in evaluating our current and ongoing operations.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021

RECONCILIATION OF NON-GAAP MEASURES

Reconciliation of Underwriting Profit

We define underwriting profit as net earned premiums and gross fee income (in specific instances when the Company is not retaining insurance risk) less losses and loss adjustment expenses on business not subject to retroactive reinsurance accounting for loss portfolio transfers and other operating expenses. Other operating expenses include the underwriting, acquisition, and insurance expenses of the operating segments and, for consolidated underwriting profit, the expenses of the Corporate and Other segment. Our definition of underwriting profit may not be comparable to that of other companies.

The following table reconciles the underwriting profit (loss) of the operating segments by individual segment to consolidated (loss) income before income taxes:

	Three Months Ended September 30,				Nine Months Ended September 30,

(1)Included in underwriting results for the three and nine months ended September 30, 2022 is gross fee income of $5.9 million and $17.4 million, respectively ($5.6 million and $16.2 million in the respective prior year periods).

Reconciliation of Adjusted Net Operating Income

Adjusted net operating income is defined as income available to common shareholders excluding a) the impact of loss portfolio transfers accounted for as retroactive reinsurance, b) net realized and unrealized gains (losses) on investments, c) certain non-operating expenses such as professional service fees related to a purported class action lawsuit, various strategic initiatives, and the filing of registration statements for the offering of securities, and d) severance costs associated with terminated employees. Adjusted net operating income should not be viewed as a substitute for net income calculated in accordance with GAAP, and our definition of adjusted net operating income may not be comparable to that of other companies.

Our income (loss) available to common shareholders reconciles to our adjusted net operating income (loss) as follows:

	Three Months Ended September 30,
	2022				2021
	Income Before Taxes		Net Income		Loss Before Taxes		Net Loss

Tangible Equity and Tangible Equity per Share

Tangible equity is defined as shareholders' equity plus mezzanine Series A Preferred Shares and the unrecognized deferred retroactive reinsurance gain on loss portfolio transfers less goodwill and intangible assets, net of amortization. Tangible equity per share represents tangible equity divided by the sum of total common shares outstanding plus the common shares resulting from an assumed conversion of the outstanding Series A Preferred Shares into common shares (at the current conversion price). Our definitions of tangible equity and tangible equity per share may not be comparable to that of other companies, and they should not be viewed as a substitute for shareholders’ equity and shareholders’ equity per share calculated in accordance with GAAP.

The following table reconciles shareholders’ equity to tangible equity as of September 30, 2022 and December 31, 2021:

	September 30, 2022				December 31, 2021

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in equity prices, interest rates, foreign currency exchange rates and commodity prices. Our consolidated balance sheets include assets and liabilities with estimated fair values that are subject to market risk. Our primary market risks have been interest rate risk associated with investments in fixed maturities and equity price risk associated with investments in equity securities. We do not have material exposure to foreign currency exchange rate risk or commodity risk.

There have been no material changes in market risk from the information provided in Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2021. The fair values of our fixed maturity securities have been negatively impacted in 2022 by higher interest rates. For the nine months ended September 30, 2022, unrealized losses on fixed maturities of $205.2 million were recognized in other comprehensive loss. Market risk was also reflected in net realized and unrealized investment losses of $29.9 million for the nine months ended September 30, 2022, which included $16.0 million and $13.8 million of unrealized losses related to changes in unrealized gains and losses on equity securities and bank loan participations, respectively.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required financial disclosure. In connection with the preparation of this quarterly report on Form 10-Q, our management carried out an evaluation, under the supervision and with the participation of our management, including the CEO and CFO, as of September 30, 2022, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of September 30, 2022.

Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our quarter ended September 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

The effectiveness of any system of controls and procedures is subject to certain limitations, and, as a result, there can be no assurance that our controls and procedures will detect all errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system will be attained.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are involved in various legal proceedings, including commercial matters and litigation regarding insurance claims which arise in the ordinary course of business, as well as an alleged class action lawsuit. In addition, the Company is involved from time to time in legal actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in handling of insurance claims. We believe that the outcome of such matters, individually and in the aggregate, is not reasonably likely to have a material adverse effect on our consolidated financial position, results of operations or cash flows.

On July 9, 2021 a purported class action lawsuit was filed in the U.S. District Court, Eastern District of Virginia (the “Court”) by Employees’ Retirement Fund of the City of Fort Worth against James River Group Holdings, Ltd. and certain of its present and former officers (together, “Defendants”). On September 22, 2021, the Court entered an order appointing Employees’ Retirement Fund of the City of Fort Worth and the City of Miami General Employees’ and Sanitation Employees’ Retirement Trust as co-lead plaintiffs (together, “Plaintiffs”). Plaintiffs’ consolidated amended complaint was filed on November 19, 2021 (the “First Amended Complaint”). The Defendants filed a motion to dismiss the First Amended Complaint on January 18, 2022, Plaintiffs’ opposition thereto was filed on March 4, 2022, and the Defendants’ reply to the Plaintiffs’ opposition was filed on April 4, 2022. On August 25, 2022, Plaintiffs filed a motion for leave to file a second amended class action complaint (the "Second Amended Complaint"). On September 8, 2022, the Defendants consented to the Plaintiffs’ motion to file the Second Amended Complaint, and filed a motion to dismiss the Second Amended Complaint on October 24, 2022 (the "Second MTD"). The Plaintiffs’ opposition to the Second MTD is due December 8, 2022, and the Defendant's reply to the Plaintiffs’ opposition is due January 9, 2023. The First Amended Complaint and Second Amended Complaint assert

60

claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of persons and entities that purchased the Company's stock between February 22, 2019 and October 25, 2021, and allege that Defendants failed to make appropriate disclosures concerning the adequacy of reserves for policies that covered Rasier LLC, a subsidiary of Uber Technologies, Inc., and seek unspecified damages, costs, attorneys’ fees and such other relief as the court may deem proper. We believe that the Plaintiffs’ claims are without merit and we intend to vigorously defend this lawsuit.

Exhibit 10.3

JAMES RIVER GROUP HOLDINGS, LTD.

2014 LONG–TERM INCENTIVE PLAN

SERVICE-BASED RESTRICTED SHARE UNIT AGREEMENT

This SERVICE-BASED RESTRICTED SHARE UNIT AGREEMENT (this “Agreement”), dated as of the Grant Date set forth in Schedule A, attached hereto and incorporated herein by reference, is made by and between James River Group Holdings, Ltd., an exempted company registered under the laws of Bermuda (the “Company”), and the Grantee listed in Schedule A.

R E C I T A L S :

WHEREAS, the Company has adopted the James River Group Holdings, Ltd. 2014 Long-Term Incentive Plan, as amended (the “Plan”); and

WHEREAS, the Company desires to grant to the Grantee Restricted Share Units pursuant to the Plan and on the terms and conditions set forth herein (the “Award”).

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Company and the Grantee hereby agree as follows:

Section 1.    Grant of Restricted Share Units. The Company hereby grants to the Grantee, pursuant to the Plan and on the terms and conditions set forth herein, the number of Restricted Share Units set forth in Schedule A. Each Restricted Share Unit represents the right to receive one Share to be issued and delivered upon becoming Vested Share Units, subject to the Restricted Share Unit becoming Vested Share Unit (as defined herein), and subject to the other terms described herein.

Section 2.    Becoming a Vested Share Unit.

(a)    Vesting of Restricted Share Units; General Rule. Except as provided in this Section 2, Restricted Share Units shall become Vested Share Units in accordance with the Vesting Schedule set forth in Schedule A. If the Grantee experiences a Separation from Service prior to one or more Continuous Service Dates (as defined in Schedule A), the Restricted Share Units that have not become Vested Share Units prior thereto shall be forfeited, except as provided in Subsections 2(b) and 2(c).

(b)    Vesting Prior to Continuous Service Date(s).

(i)    If prior to one or more Continuous Service Dates, the Grantee experiences a Separation from Service due to the Grantee’s death or Disability, the Restricted Share Units that have not become Vested Share Units prior thereto shall become Vested Share Units as of the date of death or Disability, as applicable.

(ii)    If prior to one or more Continuous Service Dates, the Grantee experiences a Separation from Service due to the Grantee’s attainment of Retirement Age, the Grantee will be deemed vested as of the date of the Separation from Service in those Restricted Share Units that would have become Vested Share Units as of the immediately succeeding Continuous Service Date had the Grantee not experienced a Separation from Service prior thereto.

(c)    Change in Control Prior to Service Condition Being Met. If a Change in Control occurs prior to any Continuous Service Dates and before the Grantee has experienced a Separation from Service and the Grantee later experiences a Separation from Service due to an involuntary termination of employment without Cause, the Company’s election not to renew the term of any employment agreement then in effect between the Company and Grantee, or a resignation by the Grantee for Good Reason, the Restricted Share Units that have not become Vested Share Units prior thereto shall become Vested Share Units.

(d)    Vested Share Units. Restricted Share Units that become vested pursuant to this Section 2 are referred to herein as a “Vested Share Unit” or, collectively, as “Vested Share Units”.

(e)    Forfeitures. Except as provided in this Section 2, upon the Grantee’s Separation from Service prior to any Restricted Shares Units becoming Vested Share Units, such Restricted Share Units shall immediately be forfeited. Upon forfeiture of Restricted Share Units, the Grantee will have no further rights with respect to those Restricted Share Units, and the Restricted Share Units shall become forfeited for no value and without any issuance of Shares.

Section 3.    Settlement of Vested Share Units. Vested Share Units shall be settled on or within thirty (30) days following the date they become Vested Share Units and shall be distributed in the form of Shares. The value of any Shares distributed in settlement of the Agreement are subject to any Company clawback policy or applicable law as in effect from time to time and, in accordance with such policy or law, may be subject to the requirement that any value delivered pursuant to the Agreement be repaid to the Company. The action permitted to be taken by the Committee under this Section is in addition to, and not in lieu of, any and all other rights of the Committee and/or the Company under applicable law and shall apply notwithstanding anything to the contrary in the Plan.

Section 4.    Shareholder Rights. No rights of a shareholder shall exist with respect to the Restricted Share Units as a result of the mere grant of the Restricted Share Units or as a result of the Restricted Share Units becoming earned or vested. Such rights shall exist only after issuance of any Shares. Without limiting the foregoing, the Grantee shall not be entitled to receive currently any dividends issued on Shares prior to the issuance of any Shares. However, the Grantee shall be credited with dividend equivalents with respect to any outstanding Restricted Share Units, and such dividend equivalents shall be subject to the same restrictions, conditions, and risks of forfeiture that apply to the Restricted Share Units to which they relate and shall be vested, payable and otherwise settled, if at all, at the same time that any underlying Restricted Share Units to which they relate are vested, payable and otherwise settled.

Section 5.    Withholding; Offset. The Company shall deduct from any payment, or otherwise collect from the Grantee, any taxes required to be withheld by federal, state, or local governments in connection with the Agreement. No opinion is expressed nor warranties made as to the effect for federal, state, or local tax purposes of the Agreement. If at any time prior to any payment the Grantee is indebted to the Company, by accepting the Award, the Grantee grants the Company the right to offset against the payment amount the amount of the Grantee’s indebtedness, but only to the extent such offset is permissible under and would not trigger adverse tax consequences under Code Section 409A.

Section 6.    No Right to Continued Service. Nothing contained herein shall be construed to confer on the Grantee any right to continue in service with the Company or to derogate from any right of the Company to retire, request the resignation of or discharge the Grantee, or to require a leave of absence of the Grantee, with or without pay, at any time, with or without Cause.

Section 7.    No Fractional Shares. No fractional Shares shall be issued in respect of Restricted Share Units, and any fractional Shares will be rounded down to the nearest whole Share.

Section 8.    Non-Transferability. The Restricted Share Units may not be assigned, transferred, or in any way encumbered except by will or the laws of descent and distribution.

Section 9.    Entire Agreement. This Agreement and the Plan contain the entire agreement between the parties hereto with respect to the matters contemplated herein and supersede all prior agreements or understandings among the parties related to such matters.

Section 10.    Binding Effect. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns and upon the Grantee and the Grantee’s assigns, heirs, executors, administrators and legal representatives.

Section 11.    Amendment and Termination. The Committee reserves the right to amend or terminate the Agreement at any time, provided that no amendment or termination (a) shall deprive the Grantee of any Restricted Share Units that have become Vested Share Units as of the amendment or termination, provided the Grantee has not experienced a Separation from Service prior to such time, except under circumstances contemplated by Sections 2(b) and 2(c), or (b) shall result in the acceleration of any settlement of the Agreement if such acceleration would result in the Grantee incurring a tax under Section 409A of the Code.

Section 12.    Governing Law. This Agreement shall be construed and enforced in accordance with the internal laws of New York, except for those matters subject to The Companies Act, 1981 of Bermuda (as amended), which shall be governed by such law, without giving effect to principles of conflicts of laws, and construed accordingly, and by applicable federal tax law.

Section 13.    Defined Terms. Capitalized terms used in this Agreement and not otherwise defined herein have the meaning ascribed to them in the Plan. The following words and phrases shall, when used herein, have the meanings set forth below:

(a)    “Cause” has the meaning ascribed to it in the Plan unless an employment agreement between the Grantee and the Company is in effect immediately prior to the Separation from Service having the same or similar term in which event such meaning provided in the employment agreement shall control for purposes of the Award.

(b)    “Change in Control” means any of the following: (i) the purchase or other acquisition (other than from the Company), in a single transaction or series of related transactions, by any person, entity, or group of persons, within the meaning of Section 13(d) or 14(d) of the Exchange Act (excluding, for this purpose, the Company or its subsidiaries or any employee benefit plan of the Company or its subsidiaries), of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of fifty percent (50%) or more of either the then-outstanding Shares or the combined voting power of the Company’s then-outstanding voting securities entitled to vote generally in the election of directors; (ii) consummation of a reorganization, merger, amalgamation, or consolidation involving the Company, in each case with respect to which persons who were the shareholders of the Company immediately prior to such reorganization, merger, amalgamation, or consolidation do not, immediately thereafter, own more than fifty percent (50%) of, respectively, the Shares and the combined voting power entitled to vote generally in the election of directors of the reorganized, merged, amalgamated, or consolidated corporation’s then-outstanding voting securities; or (iii) a liquidation or dissolution of the Company, or the sale of all or substantially all of the assets of the Company. Notwithstanding anything herein to the contrary, an event described above shall be considered a Change in Control hereunder only if it also constitutes a “change in the ownership or effective control of the corporation or in the ownership of a substantial portion of the assets of the corporation” within the meaning of Section 409A(a)(2)(v) of the Code, to the extent necessary to avoid the adverse tax consequences thereunder with respect to any payment subject to Section 409A of the Code. A Change in Control shall be deemed to occur on the date on which the event giving rise to the Change in Control occurs, provided, in the case of a Change in Control by reason of a liquidation or dissolution of the Company, such date shall be the date on which the Company shall commence such liquidation or dissolution.

(c)    “Disability” means that the Grantee is unable to engage in any substantial gainful activity by reason of a medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, or is, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three months under an accident or disability insurance benefit plan covering Company employees. The determination of whether the Grantee has a

Disability shall be determined under procedures established by the Committee. The Committee may rely on any determination that the Grantee is disabled for purposes of benefits under any long-term disability plan maintained by the Company or any Affiliate in which the Grantee, provided that the definition of disability applied under such disability plan meets the requirements of a Disability in the first sentence hereof.

(d)    “Good Reason” means the occurrence of one or more of the following without the Grantee’s express written consent, which circumstances are not remedied by the Company within thirty (30) days after its receipt of a written notice from the Grantee describing the applicable circumstances (which notice must be provided by the Grantee within ninety (90) days after the Grantee’s knowledge of the applicable circumstances): (i) any material, adverse change in the Grantee’s duties, responsibilities, authority, status, or reporting structure; (ii) a material reduction in the Grantee’s base salary; or (iii) a geographical relocation of the Grantee’s principal office location by more than fifty (50) miles; provided that, in each case, the Company has failed to cure the circumstance and the Grantee actually terminates the Grantee’s employment within thirty (30) days following the Company’s thirty (30)-day cure period; provided, however, if an employment agreement between the Grantee and the Company is in effect immediately prior to the Separation from Service having the same or similar term as “Good Reason,” then the meaning provided in the employment agreement shall control for purposes of the Award.

(e)    “Retirement Age” means the Grantee’s attainment of age 70 prior to experiencing a Separation from Service; provided, however, the Committee in its discretion may establish an earlier retirement age for the Grantee by communicating in writing that decision to the Grantee.

(f)    “Separation from Service” means a termination of the Grantee’s employment relationship with the Company where either (i) the Grantee has ceased to perform any services for the Company and all affiliated companies that, together with the Company, constitute the “service recipient” within the meaning of Code Section 409A (collectively, the “Service Recipient”) or (ii) the level of bona fide services the Grantee performs for the Service Recipient after a given date permanently decreases (excluding a decrease as a result of military leave, sick leave, or other bona fide leave of absence if the period of such leave does not exceed six months, or if longer, so long as the Grantee retains a right to reemployment with the Service Recipient under an applicable statute or by contract) to no more than twenty percent (20%) of the average level of bona fide services performed for the Service Recipient over the immediately preceding 36-month period (or the full period of service if the Grantee has been providing services to the Service Recipient for less than 36 months) that, in either case, constitutes a “separation from service” within the meaning of Code Section 409A.

(g)    “Service Condition” has the meaning ascribed to it in Schedule A.

Section 14.    Section 409A. It is intended that this Agreement shall be administered in a manner that will comply with or meet an exception from Section 409A of the Code, and this Agreement shall be administered and interpreted in accordance with such intent. Notwithstanding anything herein to the contrary, to the extent applicable, if the Grantee is a “specified employee” within the meaning of Section 409A of the Code, and to the extent necessary to avoid the adverse tax consequences under Section 409A of the Code, no portion of any payments hereunder shall be distributed on account of a Separation from Service before the earlier of: (a) the date which is six months following the date of the Grantee’s Separation from Service, or (b) the date of death of the Grantee. Amounts that would have been paid during the delay will be paid on the first business day following the six month delay.

Section 15.    The Plan. The Grantee acknowledges having received a copy of the Plan. The Restricted Share Units herein granted are subject to all of the terms and provisions of the Plan, all of which are hereby incorporated herein by reference. In the event of any inconsistency between the provisions of this Agreement and the provisions of the Plan, the provisions of the Plan shall govern.

IN WITNESS WHEREOF, the parties hereto have executed this Service-Based Restricted Share Unit Award Agreement as of the Grant Date.

Organization

James River Group Holdings, Ltd. (referred to as “JRG Holdings” or, with its subsidiaries, the “Company”) is an exempted holding company registered in Bermuda, organized for the purpose of acquiring and managing insurance and reinsurance entities.

The Company owns five insurance companies based in the United States (“U.S.”) focused on specialty insurance niches and two Bermuda-based reinsurance companies as described below:

•James River Group Holdings UK Limited (“James River UK”) is an insurance holding company formed in 2015 in the United Kingdom (“U.K.”). JRG Holdings contributed James River Group, Inc. (“James River Group”), a U.S. insurance holding company, to James River UK in 2015.

•James River Group is a Delaware domiciled insurance holding company formed in 2002 which owns all of the Company’s U.S.-based subsidiaries, either directly or indirectly through one of its wholly-owned U.S. subsidiaries. James River Group oversees the Company’s U.S. insurance operations and maintains all of the outstanding debt in the U.S.

•James River Insurance Company is an Ohio domiciled excess and surplus lines insurance company that, with its wholly-owned insurance subsidiary, James River Casualty Company, a Virginia domiciled company, is authorized to write business in every state and the District of Columbia.

•Falls Lake National Insurance Company (“Falls Lake National”) is an Ohio domiciled insurance company which wholly owns Stonewood Insurance Company (“Stonewood Insurance”), a North Carolina domiciled company, and Falls Lake Fire and Casualty Company, a California domiciled company. Falls Lake National and its subsidiaries primarily write specialty admitted fronting and program business and individual risk workers' compensation insurance.

•JRG Reinsurance Company Ltd. (“JRG Re”) was formed in 2007 and commenced operations in 2008. JRG Re, a Bermuda domiciled reinsurer, primarily provides non-catastrophe casualty reinsurance to U.S. third parties and, through December 31, 2017, to the Company’s U.S.-based insurance subsidiaries.

•Carolina Re Ltd (“Carolina Re”) was formed in 2018 and from January 1, 2018 through December 31, 2021 provided reinsurance to the Company’s U.S.-based insurance subsidiaries. During the three months ended September 30, 2022, Carolina Re commuted the majority of the outstanding obligations ceded under the intercompany quota share reinsurance agreements back to the Company’s U.S.-based insurance subsidiaries with effect from January 1, 2022. Carolina Re was also the cedent on an aggregate stop loss reinsurance treaty with JRG Re through December 31, 2021.

Basis of Presentation

The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements include the results of the Company and its subsidiaries from their respective dates of inception or acquisition, as applicable. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 for a more complete description of the Company’s business and accounting policies. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results of operations for the full year. The consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited annual consolidated financial statements.

Intercompany transactions and balances have been eliminated.

Estimates and Assumptions

Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.

Variable Interest Entities

Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to an entity on an ongoing basis.

The Company holds interests in VIEs through certain equity method investments included in “other invested assets” in the accompanying condensed consolidated balance sheets. The Company has determined that it should not consolidate any of the VIEs as it is not the primary beneficiary in any of the relationships. Although the investments resulted in the Company holding variable interests in the entities, they did not empower the Company to direct the activities that most significantly impact the economic performance of the entities. The Company’s investments related to these VIEs totaled $28.2 million and $26.9 million at September 30, 2022 and December 31, 2021, respectively, representing the Company’s maximum exposure to loss.

Income Tax Expense

Our effective tax rate fluctuates from period to period based on the relative mix of income reported by country and the respective tax rates imposed by each tax jurisdiction. For U.S.-sourced income, the Company’s U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate to income before taxes due primarily to interest income on tax-advantaged state and municipal securities, dividends received income, and excess tax benefits on share based compensation. For the nine months ended September 30, 2022, our U.S. federal income tax expense was 30.9% of the income before taxes. The effective rate exceeded the 21.0% U.S. statutory rate due to a projected annual loss in Bermuda that does not provide a tax benefit and certain discreet items including excess tax expenses associated with vested restricted share units (“RSUs”) in the nine months ended September 30, 2022. The Company had a pre-tax loss of $129.6 million for the nine months ended September 30, 2021 and recorded a U.S. federal income tax benefit of $23.1 million. For the nine months ended September 30, 2021, our U.S. federal income tax benefit was 17.8% of the loss before taxes. The pre-tax loss was largely driven by the $210.8 million of net adverse reserve development on prior accident years, including $190.7 million of net adverse development from the Excess and Surplus Lines segment that was primarily related to a former commercial auto account.

Adopted Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 simplifies the accounting for convertible debt instruments and convertible preferred stock and became effective for interim and annual periods beginning after December 15, 2021. The Company adopted the new standard concurrent with the issuance of our Series A preferred shares on March 1, 2022. Under ASU 2020-06, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. The new guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and generally requires them to include the effect of potential share settlement for instruments that may be settled in cash or shares. Adoption of the new standard did not materially impact our financial position, results of operations, or earnings per share for the nine months ended September 30, 2022.

At September 30, 2022, the Company held fixed maturity securities of 573 issuers that were in an unrealized loss position with a total fair value of $1,613.5 million and gross unrealized losses of $200.7 million. None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduled principal or interest payment. At September 30, 2022, 99.8% of the Company’s fixed maturity security portfolio was rated “BBB-” or better (“investment grade”) by Standard & Poor’s or received an equivalent rating from another nationally recognized rating agency. Fixed maturity securities with ratings below investment grade by Standard & Poor’s or another nationally recognized rating agency at September 30, 2022 had an aggregate fair value of $2.6 million and an aggregate net unrealized loss of $250,000.

The Company reviews its available-for-sale fixed maturities to determine whether unrealized losses are due to credit-related factors. An allowance for credit losses is established for any credit-related impairments, limited to the amount by which fair value is below amortized cost. Changes in the allowance for credit losses are recognized in earnings and included in net realized and unrealized gains (losses) on investments. Unrealized losses that are not credit-related are recognized in other comprehensive income.

The Company considers the extent to which fair value is below amortized cost in determining whether a credit-related loss exists. The Company also considers the credit quality rating of the security, with a special emphasis on securities downgraded below investment grade. A comparison is made between the present value of expected future cash flows for a security and its amortized cost. If the present value of future expected cash flows is less than amortized cost, a credit loss is presumed to exist and an allowance for credit losses is established. Management may conclude that a qualitative analysis is sufficient to support its conclusion that the present value of the expected cash flows equals or exceeds a security’s amortized cost. As a result of this review, management concluded that there were no credit-related impairments of fixed maturity securities at September 30, 2022, December 31, 2021, or September 30, 2021. Management does not intend to sell the securities in an unrealized loss position, and it is not “more likely than not” that the Company will be required to sell these securities before a recovery in their value to their amortized cost basis occurs.

Bank loan participations are measured at fair value pursuant to the Company's election of the fair value option, and changes in unrealized gains and losses in bank loan participations are reported in our income statement as net realized and unrealized gains (losses) on investments. Applying the fair value option to the bank loan portfolio increases volatility in the Company's financial statements, but management believes it is less subjective and less burdensome to implement and maintain than the requirements of ASU 2016-13. At September 30, 2022, the Company's bank loan portfolio had an aggregate fair value of $160.3 million and unpaid principal of $178.8 million. Investment income on bank loan participations included in net investment income was $3.4 million and $8.4 million for the three and nine months ended September 30, 2022, respectively ($2.8 million and $8.2 million for the three and nine months ended September 30, 2021, respectively). Net realized and unrealized gains (losses) on investments includes losses on bank loan participations of $2.2 million and $14.2 million for the three and nine months ended September 30, 2022, respectively (gains of $195,000 and $6.0 million for the three and nine months ended September 30, 2021, respectively). For the three and nine months ended September 30, 2022 and 2021, management concluded that none of the unrealized losses were due to credit-related impairments. Losses due to credit-related impairments are determined based upon consultations and advice from the Company's specialized investment manager and consideration of any adverse situations that could affect the borrower's ability to repay, the estimated value of underlying collateral, and other relevant factors.

Bank loan participations generally provide a higher yield than our portfolio of fixed maturities and have a credit rating that is below investment grade (i.e. below “BBB-” for Standard & Poor’s) at the date of purchase. These bank loans are primarily senior, secured floating-rate debt rated “BB”, “B”, or “CCC” by Standard & Poor’s or an equivalent rating from another nationally recognized rating agency. These bank loans include assignments of, and participations in, performing and non-performing senior corporate debt generally acquired through primary bank syndications and in secondary markets. Bank loans consist of, but are not limited to, term loans, the funded and unfunded portions of revolving credit loans, and other similar loans and investments. Management believed that it was probable at the time that these loans were acquired that the Company would be able to collect all contractually required payments receivable.

Interest income on bank loan participations is accrued on the unpaid principal balance, and discounts and premiums on bank loan participations are amortized to income using the interest method. Generally, the accrual of interest on a bank loan participation is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest. A bank loan participation may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Generally, bank loan participations are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Interest received on nonaccrual loans generally is reported as investment income. There were no bank loans on nonaccrual status at September 30, 2022 or December 31, 2021.

The Company’s net realized and unrealized gains and losses on investments are summarized as follows:

(a)The Company's Excess and Surplus Lines and Corporate and Other segments own equity interests ranging from 2.6% to 32.6% in various LLCs whose principal objective is capital appreciation and income generation from owning and operating renewable energy production facilities (wind and solar). The LLCs are managed by an entity for which two former directors served as officers, and the Company’s Non-Executive Chairman has invested in certain of these LLCs. The equity method is used to account for the Company’s LLC investments. Income for the LLCs primarily reflects adjustments to the carrying values of investments in renewable energy projects to their determined fair values. The fair value adjustments are included in revenues for the LLCs. Expenses for the LLCs are not significant and are comprised of administrative and interest expenses. The Company received cash distributions from these investments totaling $1.4 million and $1.8 million in the nine months ended September 30, 2022 and 2021, respectively.

(b)The Company's Excess and Surplus Lines and Corporate and Other segments have invested in notes receivable for renewable energy projects. At September 30, 2022, the Company held two notes issued by an entity for which two of our former directors serve as officers. Interest on the notes, which mature in 2025, is fixed at 12%.

(c)The Company owns investments in limited partnerships that invest in concentrated portfolios including publicly-traded small cap equities, loans of middle market private equity sponsored companies, private equity general partnership interests, commercial mortgage-backed securities, and tranches of distressed home loans. Income from the partnerships is recognized under the equity method of accounting. During the three and nine months ended September 30, 2022, the Company recognized an impairment loss of $392,000 on one limited partnership in the Corporate & Other segment. At September 30, 2022, the Company’s Excess and Surplus Lines segment has outstanding commitments to invest another $5.3 million in the other limited partnerships.

(d)The Company's Excess and Surplus Lines segment holds $4.5 million of subordinated notes issued by a bank holding company for which the Company’s Non-Executive Chairman was previously the Lead Independent Director and an investor

and for which one of the Company’s directors is also an investor (the "Bank Holding Company"). Interest on the notes, which mature on August 12, 2023, is fixed at 7.6% per annum.

The Company experienced $1.1 million of net favorable reserve development in the three months ended September 30, 2022 on the reserve for losses and loss adjustment expenses held at December 31, 2021 (excluding adverse prior year development on the legacy commercial auto business subject to retroactive reinsurance accounting - see Commercial Auto Loss Portfolio Transfer below). This reserve development included $139,000 of net adverse development in the Excess and Surplus Lines segment, $1.3 million of net favorable development in the Specialty Admitted Insurance segment, and no development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the three months ended September 30, 2022 related to Hurricane Ian. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

The Company experienced $44.1 million of net adverse reserve development in the three months ended September 30, 2021 on the reserve for losses and loss adjustment expenses held at December 31, 2020. This reserve development included $29.5 million of net adverse development in the Excess and Surplus Lines segment (see Commercial Auto Loss Portfolio Transfer below), $500,000 of net favorable development in the Specialty Admitted Insurance segment, and $15.1 million of net adverse development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the three months ended September 30, 2021 related to Hurricane Ida. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

The Company experienced $4.1 million of net adverse reserve development in the nine months ended September 30, 2022 on the reserve for losses and loss adjustment expenses held at December 31, 2021 (excluding adverse prior year development on the legacy commercial auto business subject to retroactive reinsurance accounting - see Commercial Auto Loss Portfolio Transfer below). This reserve development included $48,000 of net adverse development in the Excess and Surplus Lines segment, $2.8 million of net favorable development in the Specialty Admitted Insurance segment, and $6.8 million of net adverse development in the Casualty Reinsurance segment that was associated with the Retrocession Agreement (as defined below). The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the nine months ended September 30, 2022 related to Hurricane Ian. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

The Company experienced $210.8 million of net adverse reserve development in the nine months ended September 30, 2021 on the reserve for losses and loss adjustment expenses held at December 31, 2020. This reserve development included $190.7 million of net adverse development in the Excess and Surplus Lines segment including $200.1 million on commercial auto business almost entirely related to a previously canceled account that has been in runoff since 2019. The reported losses on this terminated commercial auto account meaningfully exceeded our expectations for the three months ended March 31, 2021. We had expected that reported losses would decline as the account moved further into runoff, but the continued heavy reported loss emergence in the first quarter of 2021 indicated more inherent severity than anticipated. The continuation of the highly elevated reported losses in the first quarter of 2021 led us to conclude that using only our own loss experience in our paid and incurred reserve projections rather than industry data inputs that we had used in prior quarters, and giving greater weight to incurred methods, would give us a better estimate of ultimate losses on this account. In response, we meaningfully adjusted our actuarial methodology, resulting in a significant strengthening of reserves for this account at March 31, 2021. Loss emergence on the terminated commercial auto account in the second quarter was in line with our expectations, and accordingly, no additional reserve development was taken. In the third quarter, an additional $29.6 million was recognized as adverse loss and loss adjustment reserve development upon entering the loss portfolio transaction as described below. The Company experienced $2.5 million of net favorable development in the Specialty Admitted Insurance segment due to favorable development in the workers' compensation business for prior accident years, and $22.6 million of net adverse development in the Casualty Reinsurance segment. The Company also experienced $5.0 million of net catastrophe losses in the current accident year for the nine months ended September 30, 2021 related to Hurricane Ida. The losses were primarily in the Excess Property book in the Excess and Surplus Lines segment.

Loss Portfolio Transfers

Loss portfolio transfers are a form of reinsurance utilized by the Company to transfer losses and loss adjustment expenses and associated risk of adverse development on covered subject business, as defined in the respective agreements, to an assuming reinsurer in exchange for a reinsurance premium. Loss portfolio transfers can bring economic finality on the subject risks when they no longer meet the Company's appetite or are no longer aligned with our risk management guidelines.

The Company periodically reevaluates the remaining reserves subject to its loss portfolio transfers, and when recognized adverse prior year development on the subject business causes the cumulative amounts ceded under a loss portfolio transfer to exceed the consideration paid, the loss portfolio transfer moves into a gain position subject to retroactive reinsurance accounting under GAAP. Gains are deferred under retroactive reinsurance accounting and recognized in earnings in proportion to actual paid recoveries under the loss portfolio transfer using the recovery method. While the deferral of gains can introduce volatility in our results in the short-term, over the life of the contract, we would expect no economic impact to the Company as long as any additional losses are within the limit of the loss portfolio transfer and the counterparty performs under the contract. The impact of retroactive reinsurance accounting is not indicative of our current and ongoing operations.

Loss Portfolio Transfer Retrocession Agreement

On February 23, 2022, JRG Re entered into a loss portfolio transfer retrocession agreement (the “Retrocession Agreement”) with Fortitude Reinsurance Company Ltd. (“FRL”) under which FRL reinsures the majority of the reserves in the Company’s Casualty Reinsurance segment. Under the terms of the transaction, which closed on March 31, 2022 (the “Retrocession Closing Date”), JRG Re (a) ceded to FRL all existing and future claims for losses arising under certain casualty reinsurance agreements with underlying insurance companies with treaty inception dates ranging from 2011 to 2020 (the “Subject Business”), in each case net of third-party reinsurance and other recoveries, up to an aggregate limit of $400.0 million; (b) continues to manage and retain the benefit of other third-party reinsurance on the Subject Business; (c) paid FRL a reinsurance premium of $335.0 million, $310.0 million of which JRG Re credited to a notional funds withheld account (the “Funds Withheld Account”) and $25.0 million of which was paid in cash to FRL; and (d) pays FRL a 2% per annum crediting rate on the Funds Withheld Account balance on a quarterly basis. The total premium, initial Funds Withheld Account credit, and aggregate limit was adjusted for claims paid from October 1, 2021 to the Retrocession Closing Date. The Casualty

Reinsurance segment incurred losses of $11.5 million (including $6.8 million of net adverse reserve development and $4.7 million of current accident year losses) in the three months ended March 31, 2022 associated with the Retrocession Agreement.

Commercial Auto Loss Portfolio Transfer

On September 27, 2021, James River Insurance Company and James River Casualty Company (together, “James River”) entered into a loss portfolio transfer transaction (the “Commercial Auto LPT”) with Aleka Insurance, Inc. (“Aleka”), a captive insurance company affiliate of Rasier LLC, to reinsure substantially all of the Excess and Surplus Lines segment's legacy portfolio of commercial auto policies previously issued to Rasier LLC and its affiliates (collectively, “Rasier”) for which James River is not otherwise indemnified by Rasier. Under the terms of the transaction, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier policies written in the years 2013-2019, which amount constituted the reinsurance premium. The reinsurance coverage is structured to be fully collateralized, is not subject to an aggregate limit, and is subject to certain exclusions. A pre-tax loss of $29.6 million was recognized as adverse loss and loss adjustment reserve development in the Excess and Surplus Lines segment for the third quarter of 2021 associated with the loss portfolio transfer.

For the three and nine months ended September 30, 2022, due to adverse paid loss trends on the legacy Rasier business, the Company recognized adverse prior year development of $46.7 million on the reserves subject to the Commercial Auto LPT, resulting in a corresponding additional amount ceded under the Commercial Auto LPT. As a result, the cumulative amounts ceded under the Commercial Auto LPT exceed the consideration paid, moving the Commercial Auto LPT into a gain position. The Company has applied retroactive reinsurance accounting to the Commercial Auto LPT. A retroactive reinsurance benefit of $25.9 million was recorded in losses and loss adjustment expenses on the Condensed Consolidated Statements of (Loss) Income and Comprehensive Loss for the three and nine months ended September 30, 2022 using the recovery method. As of September 30, 2022 and December 31, 2021, the cumulative amounts ceded under the Commercial Auto LPT were $391.8 million and $345.1 million, respectively. The unrecognized deferred retroactive reinsurance gain of $20.8 million at September 30, 2022 is separately presented on the Company's Condensed Consolidated Balance Sheets.

In the nine months ended September 30, 2022 and 2021, the fair values of our fixed maturity securities were negatively impacted by rising interest rates leading to unrealized losses recognized in other comprehensive loss.

In addition to the $972,000 of net realized investment losses and $284,000 of net realized investment gains on available-for-sale fixed maturities for the three and nine months ended September 30, 2022 ($3.2 million and $4.3 million of net realized investment gains for the three and nine months ended September 30, 2021, respectively), the Company also recognized net realized and unrealized investment losses in the respective periods of $2.2 million and $14.2 million on its investments in bank loan participations ($195,000 and $6.0 million of net realized and unrealized investment gains in the respective prior year periods) and net realized and unrealized investment losses of $4.6 million and $15.9 million on its investments in equity securities ($641,000 and $3.4 million of net realized and unrealized investment gains in the respective prior year periods) that was largely related to preferred stock holdings.

Commitments and Contingencies Disclosure [Abstract]

Contingent Liabilities

Contingent Liabilities

The Company is involved in various legal proceedings, including commercial matters and litigation regarding insurance claims arising in the ordinary course of business as well as an alleged class action lawsuit. In addition, the Company is involved from time to time in legal actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in the handling of insurance claims. The Company believes that the outcome of such matters, individually and in the aggregate, is not reasonably likely to have a material adverse effect on its consolidated financial position, results of operations or cash flows.

On July 9, 2021 a purported class action lawsuit was filed in the U.S. District Court, Eastern District of Virginia (the “Court”) by Employees’ Retirement Fund of the City of Fort Worth against James River Group Holdings, Ltd. and certain of its present and former officers (together, “Defendants”). On September 22, 2021, the Court entered an order appointing Employees’ Retirement Fund of the City of Fort Worth and the City of Miami General Employees’ and Sanitation Employees’ Retirement Trust as co-lead plaintiffs (together, “Plaintiffs”). Plaintiffs’ consolidated amended complaint was filed on November 19, 2021 (the “First Amended Complaint”). The Defendants filed a motion to dismiss the First Amended Complaint on January 18, 2022, Plaintiffs’ opposition thereto was filed on March 4, 2022, and the Defendants’ reply to the Plaintiffs’ opposition was filed on April 4, 2022. On August 25, 2022, Plaintiffs filed a motion for leave to file a second amended class action complaint (the "Second Amended Complaint"). On September 8, 2022, the Defendants consented to the Plaintiffs’ motion to file the Second Amended Complaint, and filed a motion to dismiss the Second Amended Complaint on October 24, 2022 (the "Second MTD"). The Plaintiffs’ opposition to the Second MTD is due December 8, 2022, and the Defendant's reply to the Plaintiffs’ opposition is due January 9, 2023. The First Amended Complaint and Second Amended Complaint assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of persons and entities that purchased the Company's stock between February 22, 2019 and October 25, 2021, and allege that Defendants failed to make appropriate disclosures concerning the adequacy of reserves for policies that covered Rasier LLC, a subsidiary of Uber Technologies, Inc., and seek unspecified damages, costs, attorneys’ fees and such other relief as the court may deem proper. We believe that the Plaintiffs’ claims are without merit and we intend to vigorously defend this lawsuit.

For a description of the potential future impacts of COVID-19 on the Company, see the “The global coronavirus outbreak could harm business and results of operations of the Company” risk factor in Part I—Item IA in our Annual Report on Form 10-K for the year ended December 31, 2021.

The Company’s reinsurance subsidiary, JRG Re, entered into three letter of credit facilities with banks as security to third-party reinsureds on reinsurance assumed by JRG Re. JRG Re has established custodial accounts to secure these letters of credit. Under a $30.0 million facility, $4.6 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $7.8 million. Under a $102.5 million facility, $40.5 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $46.0 million. Under a $100.0 million facility, $22.6 million of letters of credit were issued through September 30, 2022 which were secured by deposits of $27.5 million. JRG Re has also established trust accounts to secure its obligations to selected reinsureds. The total amount deposited in the trust accounts for the benefit of third-party reinsureds was $409.3 million at September 30, 2022.

Amounts Recoverable from an Indemnifying Party and Reinsurer on Legacy Commercial Auto Book

James River previously issued a set of commercial auto insurance contracts (the “Rasier Commercial Auto Policies”) to Rasier under which James River pays losses and loss adjustment expenses on the contracts. James River has indemnity agreements with Rasier (non-insurance entities) (collectively, the “Indemnity Agreements”) and is contractually entitled to reimbursement for the portion of the losses and loss adjustment expenses paid on behalf of Rasier under the Rasier Commercial Auto Policies and other expenses incurred by James River. On September 27, 2021, James River entered into the Commercial Auto LPT with Aleka to reinsure substantially all of the Rasier Commercial Auto Policies for which James River is not otherwise indemnified by Rasier under the Indemnity Agreements. Under the terms of the Commercial Auto LPT, effective as of July 1, 2021, James River ceded to Aleka approximately $345.1 million of commercial auto liabilities relating to Rasier Commercial Auto Policies written in the years 2013-2019, which amount constituted the reinsurance premium.

Each of Rasier and Aleka are required to post collateral under the Indemnity Agreements and the Commercial Auto LPT, respectively:

•Pursuant to the Indemnity Agreements, Rasier is required to post collateral equal to 102% of James River's estimate of the amounts that are recoverable or may be recoverable under the indemnity agreements, including, among other things, case loss and loss adjustment expense reserves, IBNR loss and loss adjustment expense reserves, extra contractual obligations and excess policy limits liabilities. The collateral is provided through a collateral trust arrangement (the “Indemnity Trust”) in favor of James River by Aleka. In connection with the execution of the Commercial Auto LPT, James River returned $691.3 million to the Indemnity Trust, representing the remaining balance of the amount withdrawn in October 2019, as was permitted under the indemnification agreements with Rasier and the associated trust agreement. At September 30, 2022, the balance in the Indemnity Trust was $262.1 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Indemnity Agreements as described below, the total balance of collateral securing Rasier’s obligations under the Indemnity Agreements was $331.3 million.

•Pursuant to the Commercial Auto LPT, Aleka is required to post collateral equal to 102% of James River's estimate of Aleka's obligations under the Commercial Auto LPT, calculated in accordance with statutory accounting principles. The collateral is provided through a collateral trust arrangement (the “LPT Trust”) established in favor of James River by Aleka. At September 30, 2022, the balance in the LPT Trust was $118.3 million, and, together with the balance of the Loss Fund Trust (as defined below) attributable to the Commercial Auto LPT as described below, the total balance of collateral securing Aleka’s obligations under the Commercial Auto LPT was $146.5 million. At September 30, 2022, the total reinsurance recoverables under the Commercial Auto LPT was $189.1 million (including $174.3 million of unpaid recoverables and $14.8 million of paid recoverables).

In connection with the execution of the Commercial Auto LPT, James River and Aleka entered into an administrative services agreement (the “Administrative Services Agreement”) with a third party claims administrator (the “Administrator”) pursuant to which the Administrator handles the claims on the Rasier Commercial Auto Policies for the remaining life of those claims. The claims paid by the Administrator are reimbursable by James River, and pursuant to the Administrative Services Agreement, James River established a loss fund trust account for the benefit of the Administrator (the “Loss Fund Trust”) to collateralize its claims payment reimbursement obligations. James River funds the Loss Fund Trust using funds withdrawn from the Indemnity Trust, funds withdrawn from the LPT Trust, and its own funds, in each case in an amount equal to the pro rata portion of the required Loss Fund Trust balance attributable to the Indemnity Agreements, the Commercial Auto LPT and James River’s existing third party reinsurance agreements, respectively. At September 30, 2022, the balance in the Loss Fund Trust was $102.5 million, including $69.2 million representing collateral supporting Rasier’s obligations under the Indemnity Agreements and $28.2 million representing collateral supporting Aleka’s obligations under the Commercial Auto LPT. Funds posted to the Loss Fund Trust are classified as restricted cash equivalents on the Company's balance sheets.

While the Commercial Auto LPT brings economic finality to substantially all of the Rasier Commercial Auto Policies, the Company has credit exposure to Rasier and Aleka under the Indemnity Agreements and the Commercial Auto LPT if the estimated losses and expenses of the Rasier Commercial Auto Policies grow at a faster pace than the growth in our collateral balances. In addition, we have credit exposure if our estimates of future losses and loss adjustment expenses and other amounts recoverable under the Indemnity Agreements and the Commercial Auto LPT, which are the basis for establishing the collateral balances, are lower than actual amounts paid or payable. The amount of our credit exposure in any of these instances could be material. To mitigate these risks, we closely and frequently monitor our exposure compared to our collateral held, and we request additional collateral in accordance with the terms of the Commercial Auto LPT and Indemnity Agreements when our analysis indicates that we have uncollateralized exposure.

Segment Reporting [Abstract]

Segment Information

Segment InformationThe Company has four reportable segments: the Excess and Surplus Lines segment, the Specialty Admitted Insurance segment, the Casualty Reinsurance segment, and the Corporate and Other segment. Segment profit (loss) is measured by underwriting profit (loss), which is generally defined as net earned premiums and gross fee income (in specific instances when the Company is not retaining insurance risk) in “other income” in the condensed consolidated statements of income (loss) and comprehensive (loss) income less loss and loss adjustment expenses on business not subject to retroactive reinsurance accounting for loss portfolio transfers (see Loss Portfolio Transfers in Note 5 - Reserve for Losses and Loss Adjustment Expenses) and other operating expenses of the operating segments. Gross fee income of $914,000 and $2.6 million for the Specialty Admitted Insurance segment was included in other income and in underwriting profit (loss) for the three and nine months ended September 30, 2022, respectively ($1.0 million and $2.9 million in the respective prior year periods). Segment results are reported prior to the effects of intercompany reinsurance agreements among the Company’s insurance subsidiaries.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Three levels of inputs are used to measure fair value of financial instruments: (1) Level 1: quoted price (unadjusted) in active markets for identical assets, (2) Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument, and (3) Level 3: inputs to the valuation methodology are unobservable for the asset or liability.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date.

The fair values of fixed maturity securities, equity securities, and bank loan participations have been determined using fair value prices provided by the Company’s investment accounting services provider or investment managers, who utilize internationally recognized independent pricing services. The prices provided by the independent pricing services are generally

based on observable market data in active markets (e.g. broker quotes and prices observed for comparable securities). Values for U.S. Treasury and publicly-traded equity securities are generally based on Level 1 inputs which use the market approach valuation technique. The values for all other fixed maturity securities (including state and municipal securities and obligations of U.S. government corporations and agencies) and bank loan participations generally incorporate significant Level 2 inputs, and in some cases, Level 3 inputs, using the market approach and income approach valuation techniques. There have been no changes in the Company’s use of valuation techniques since December 31, 2020.

The Company reviews fair value prices provided by its outside investment accounting service provider or investment managers for reasonableness by comparing the fair values provided by the managers to those provided by its investment custodian. The Company also reviews and monitors changes in unrealized gains and losses. The Company has not historically adjusted security prices. The Company obtains an understanding of the methods, models and inputs used by the investment managers and independent pricing services, and controls are in place to validate that prices provided represent fair values. The Company’s control process includes, but is not limited to, initial and ongoing evaluation of the methodologies used, a review of specific securities and an assessment for proper classification within the fair value hierarchy, and obtaining and reviewing internal control reports for our investment manager that obtains fair values from independent pricing services.

Assets measured at fair value on a recurring basis as of September 30, 2022 are summarized below:

The Company had one equity security at December 31, 2021 for which the fair value was determined using significant unobservable inputs (Level 3). The fair value of $102,000 for the equity security was based on expected proceeds from its sale. During the nine months ended September 30, 2022, the Company sold the equity security.

The Company held one bank loan participation and three equity securities at September 30, 2021 and one bank loan participation and two equity securities at December 31, 2020 for which the fair value was determined using significant unobservable inputs (Level 3). A market approach using prices in trades of comparable securities was utilized to determine a fair value for the securities of $372,000 at September 30, 2021 and $980,000 at December 31, 2020.

Transfers out of Level 3 occur when the Company is able to obtain reliable prices from pricing vendors for securities for which the Company was previously unable to obtain reliable prices. Transfers in to Level 3 occur when the Company is unable to obtain reliable prices for securities from pricing vendors and instead must use broker price quotes to value the securities.

There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2022 or 2021. The Company recognizes transfers between levels at the beginning of the reporting period.

In the determination of the fair value for bank loan participations and certain high yield bonds, the Company’s investment manager endeavors to obtain data from multiple external pricing sources. External pricing sources may include brokers, dealers and price data vendors that provide a composite price based on prices from multiple dealers. Such external pricing sources typically provide valuations for normal institutional size trading units of such securities using methods based on market transactions for comparable securities, and various relationships between securities, as generally recognized by institutional dealers. For investments in which the investment manager determines that only one external pricing source is appropriate or if only one external price is available, the relevant investment is generally recorded at fair value based on such price.

Investments for which external sources are not available or are determined by the investment manager not to be representative of fair value are recorded at fair value as determined by the Company, with input from its investment managers and valuation specialists as considered necessary. In determining the fair value of such investments, the Company considers one or more of the following factors: type of security held, convertibility or exchangeability of the security, redeemability of the security (including the timing of redemptions), application of industry accepted valuation models, recent trading activity, liquidity, estimates of liquidation value, purchase cost, and prices received for securities with similar terms of the same issuer or similar issuers. At September 30, 2022 and December 31, 2021, there were no investments for which external sources were unavailable to determine fair value.

The fair values of fixed maturity securities, equity securities, and bank loan participations have been determined using quoted market prices for securities traded in the public market or prices using bid or closing prices for securities not traded in the public marketplace. The fair values of cash and cash equivalents and short-term investments approximate their carrying values due to their short-term maturity.

The fair values of other invested assets-notes receivable, senior debt, and junior subordinated debt at September 30, 2022 and December 31, 2021 were determined by calculating the present value of expected future cash flows under the terms of the note agreements or debt agreements, as applicable, discounted at an estimated market rate of interest at September 30, 2022 and December 31, 2021, respectively.

The fair values of senior debt and junior subordinated debt at September 30, 2022 and December 31, 2021 were determined using inputs to the valuation methodology that are unobservable (Level 3).

Series A Preferred Shares

Temporary Equity [Abstract]

Series A Preferred Shares

Series A Preferred Shares

On February 24, 2022, we entered into an Investment Agreement with GPC Partners Investments (Thames) LP (“GPC Partners”), an affiliate of Gallatin Point Capital LLC, relating to the issuance and sale of 150,000 7% Series A Perpetual Cumulative Convertible Preferred Shares, par value $0.00125 per share (the “Series A Preferred Shares”), for an aggregate purchase price of $150.0 million, or $1,000 per share, in a private placement. The transaction closed on March 1, 2022 (the “Series A Closing Date”).

The Series A Preferred Shares rank senior to our common shares with respect to dividend rights and rights on the distribution of assets on any liquidation, dissolution or winding up of the affairs of the Company, upon which the holders of Series A Preferred Shares would receive the greater of the $1,000 liquidation preference per share (the “Liquidation Preference”) plus accrued and unpaid dividends, or the amount they would have received if they had converted all of their Series A Preferred Shares to common shares immediately before such liquidation, dissolution or winding up.

Holders of the Series A Preferred Shares are entitled to a dividend at the initial rate of 7% of the Liquidation Preference per annum, paid in cash, in-kind in common shares or in Series A Preferred Shares, at our election. On the five-year anniversary of the Series A Closing Date, and each five-year anniversary thereafter, the dividend rate will reset to a rate equal to the five-year U.S. treasury rate plus 5.2%. Dividends accrue quarterly and are payable on March 31, June 30, September 30 and December 31 of each year. Cash dividends of $6.1 million have been paid in the nine months ended September 30, 2022, including $3.5 million on June 30, 2022 for the period from the Series A Closing Date through June 30, 2022, and $2.6 million on September 30, 2022.

The Series A Preferred Shares are convertible at the option of the holders thereof at any time into common shares at an initial conversion price of $26.5950, making the Series A Preferred Shares initially convertible into 5,640,158 common shares. The conversion price is subject to customary anti-dilution adjustments, including cash dividends on the common shares above specified levels, as well as certain adjustments in case of adverse reserve developments.

At any time on or after the two year anniversary of the Series A Closing Date, if the volume-weighted average price (“VWAP”) per Common Share is greater than 130% of the then-applicable conversion price for at least twenty (20) consecutive trading days, the Company will be able to elect to convert (a “Mandatory Conversion”) all of the outstanding Series A Preferred Shares into Common Shares. In the case of a Mandatory Conversion, each Series A Preferred Share then outstanding will be converted into (i) the number of Common Shares equal to the quotient of (A) the sum of the Liquidation Preference and the accrued and unpaid dividends with respect to such Series A Preferred Share to be converted divided by (B) the conversion price of such share in effect as of the date of the Mandatory Conversion plus (ii) cash in lieu of fractional shares.

Upon any Mandatory Conversion on or before the five-year anniversary of the Series A Closing Date, all dividends that would have accrued from the date of the Mandatory Conversion to the later of the five-year anniversary of the Series A Closing Date or the last day of the eighth quarter following the date of the Mandatory Conversion, the last eight quarters of which will be discounted to present value using a discount rate of 3.5% per annum, and will be immediately payable in Common Shares, valued at the average of the daily VWAP of the Company’s Common Shares during the five (5) trading days immediately preceding the Mandatory Conversion.

The holders of the Series A Preferred Shares may require us to repurchase their shares upon the occurrence of certain change of control events. Upon the occurrence of a Fundamental Change (as defined in the Certificate of Designations designating the Series A Preferred Shares), each holder of outstanding Series A Preferred Shares will be permitted to, at its election, (i) effective as of immediately prior to the Fundamental Change, convert all or a portion of its Series A Preferred Shares into Common Shares, or (ii) require the Company to repurchase any or all of such holder’s Series A Preferred Shares at a purchase price per Series A Preferred Share equal to the Liquidation Preference of such Series A Preferred Share plus accrued and unpaid dividends. The repurchase price will be payable in cash.

Because the Company may be required to repurchase all or a portion of the Series A Preferred Shares at the option of the holder upon the occurrence of certain change of control events, the Series A Preferred Shares have been classified as mezzanine equity in the Company's condensed consolidated balance sheets and are recognized at fair value of $150.0 million (the proceeds on the date of issuance) less issuance costs of $5.1 million, resulting in a carrying value of $144.9 million.

Under the terms of the Investment Agreement, GPC Partners has the right to designate one member of the Board (the “Series A Designee”). GPC Partners has designated Matthew Botein as the Series A Designee and, accordingly, the Board approved the appointment of Mr. Botein to serve as a Class I director with a term expiring at the 2024 annual meeting of the Company’s shareholders, effective following receipt of any necessary regulatory approvals. Until applicable regulatory approvals are obtained, Mr. Botein will have board observer status.

Equity Incentive Plans

The Company’s shareholders have approved various equity incentive plans, including the 2014 Long Term Incentive Plan (“2014 LTIP”) and the 2014 Non-Employee Director Incentive Plan (“2014 Director Plan”) (collectively, the “Plans”). All awards issued under the Plans are issued at the discretion of the Board of Directors.

Employees are eligible to receive non-qualified stock options, incentive stock options, share appreciation rights, performance shares, restricted shares, RSUs, and other awards under the 2014 LTIP. The maximum number of shares available for issuance under the 2014 LTIP is 4,171,150, and at September 30, 2022, 807,839 shares are available for grant.

On July 26, 2022, the Board of Directors of the Company approved a new long-term incentive plan (the “LTI Plan”). The LTI Plan is designed to align compensation of designated senior officers of the Company with Company performance and shareholder interests over the long-term. Awards under the LTI Plan will be made in the form of performance restricted share units (a “PRSU”) and service based restricted share units (RSUs), with initial awards intended to be made in February 2023.

Each PRSU will represent a contingent right to receive one Company common share based upon the level of achievement of certain performance metrics during the performance period, with payout for achievement of threshold, target and maximum performance levels to be set at 50%, 100% and 200% of the target number of PRSUs, respectively. The initial PRSU awards are intended to have a performance period of January 1, 2023 through December 31, 2025.

Non-employee directors of the Company are eligible to receive non-qualified stock options, share appreciation rights, performance shares, restricted shares, RSUs, and other awards under the 2014 Director Plan. The maximum number of shares available for issuance under the 2014 Director Plan is 150,000, and at September 30, 2022, 77,708 shares are available for grant.

Generally, awards issued under the 2014 LTIP and 2014 Director Plan vest immediately in the event that an award recipient is terminated without Cause (as defined in the applicable plans), and in the case of the 2014 LTIP for Good Reason (as defined in the applicable plans), at any time following a Change in Control (as defined in the applicable plans).

All of the outstanding options are fully vested (vesting period of three years from date of grant) and have a contractual life of seven years from the original date of grant. All of the outstanding options have an exercise price equal to the fair value of the underlying shares at the date of grant. The weighted-average remaining contractual life of the options outstanding and exercisable at September 30, 2022 was 0.7 years.

RSUs

The following table summarizes RSU activity:

	Nine Months Ended September 30,

Unvested, end of period	715,298	$	26.94	317,832	$	47.00

Outstanding RSUs granted to employees generally vest ratably over a three year vesting period. RSUs granted to non-employee directors have a one year vesting period. The holders of RSUs are entitled to dividend equivalents. The dividend equivalents are settled in cash at the same time that the underlying RSUs vest and are subject to the same risk of forfeiture as the underlying shares. The fair value of the RSUs granted is based on the market price of the underlying shares at the date of grant.

Compensation Expense

Share based compensation expense is recognized on a straight-line basis over the vesting period. The amount of expense and related tax benefit is summarized below:

	Three Months Ended September 30,				Nine Months Ended September 30,

Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements include the results of the Company and its subsidiaries from their respective dates of inception or acquisition, as applicable. Readers are urged to review the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 for a more complete description of the Company’s business and accounting policies. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results of operations for the full year. The consolidated balance sheet as of December 31, 2021 was derived from the Company’s audited annual consolidated financial statements.

Intercompany transactions and balances have been eliminated.

Estimates and Assumptions

Estimates and Assumptions

Preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.

Variable Interest Entities

Variable Interest Entities

Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to an entity on an ongoing basis.

The Company holds interests in VIEs through certain equity method investments included in “other invested assets” in the accompanying condensed consolidated balance sheets. The Company has determined that it should not consolidate any of the VIEs as it is not the primary beneficiary in any of the relationships. Although the investments resulted in the Company holding variable interests in the entities, they did not empower the Company to direct the activities that most significantly impact the economic performance of the entities.

Income Tax Expense

Income Tax ExpenseOur effective tax rate fluctuates from period to period based on the relative mix of income reported by country and the respective tax rates imposed by each tax jurisdiction. For U.S.-sourced income, the Company’s U.S. federal income tax expense differs from the amounts computed by applying the federal statutory income tax rate to income before taxes due primarily to interest income on tax-advantaged state and municipal securities, dividends received income, and excess tax benefits on share based compensation.

Adopted Accounting Standards

Adopted Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 simplifies the accounting for convertible debt instruments and convertible preferred stock and became effective for interim and annual periods beginning after December 15, 2021. The Company adopted the new standard concurrent with the issuance of our Series A preferred shares on March 1, 2022. Under ASU 2020-06, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. The new guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and generally requires them to include the effect of potential share settlement for instruments that may be settled in cash or shares. Adoption of the new standard did not materially impact our financial position, results of operations, or earnings per share for the nine months ended September 30, 2022.

(a)The Company's Excess and Surplus Lines and Corporate and Other segments own equity interests ranging from 2.6% to 32.6% in various LLCs whose principal objective is capital appreciation and income generation from owning and operating renewable energy production facilities (wind and solar). The LLCs are managed by an entity for which two former directors served as officers, and the Company’s Non-Executive Chairman has invested in certain of these LLCs. The equity method is used to account for the Company’s LLC investments. Income for the LLCs primarily reflects adjustments to the carrying values of investments in renewable energy projects to their determined fair values. The fair value adjustments are included in revenues for the LLCs. Expenses for the LLCs are not significant and are comprised of administrative and interest expenses. The Company received cash distributions from these investments totaling $1.4 million and $1.8 million in the nine months ended September 30, 2022 and 2021, respectively.

(b)The Company's Excess and Surplus Lines and Corporate and Other segments have invested in notes receivable for renewable energy projects. At September 30, 2022, the Company held two notes issued by an entity for which two of our former directors serve as officers. Interest on the notes, which mature in 2025, is fixed at 12%.

(c)The Company owns investments in limited partnerships that invest in concentrated portfolios including publicly-traded small cap equities, loans of middle market private equity sponsored companies, private equity general partnership interests, commercial mortgage-backed securities, and tranches of distressed home loans. Income from the partnerships is recognized under the equity method of accounting. During the three and nine months ended September 30, 2022, the Company recognized an impairment loss of $392,000 on one limited partnership in the Corporate & Other segment. At September 30, 2022, the Company’s Excess and Surplus Lines segment has outstanding commitments to invest another $5.3 million in the other limited partnerships.

(d)The Company's Excess and Surplus Lines segment holds $4.5 million of subordinated notes issued by a bank holding company for which the Company’s Non-Executive Chairman was previously the Lead Independent Director and an investor

and for which one of the Company’s directors is also an investor (the "Bank Holding Company"). Interest on the notes, which mature on August 12, 2023, is fixed at 7.6% per annum.
