Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), which vary in some respects from statutory accounting practices (“SAP”) which are prescribed or permitted by the various state insurance departments in the U.S. The accompanying consolidated financial statements include the accounts and operations of the Company and its subsidiaries. Intercompany transactions and balances have been eliminated.
Discontinued Operations	Discontinued Operations The results of operations of a component of the Company are reported in discontinued operations when certain criteria are met as of the date of disposal, or earlier if classified as held-for-sale. The Company determined that the sale of JRG Re, which closed on April 16, 2024, represented a strategic shift that had a major effect on the Company's operations. Accordingly, the results of JRG Re's operations have been presented as discontinued operations for all periods presented in this Annual Report on Form 10-K.
Estimates and Assumptions	Estimates and Assumptions Preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. Those estimates are inherently subject to change, and actual results may ultimately differ from those estimates.
Fixed Maturity and Equity Securities	Fixed Maturity and Equity Securities Fixed maturity securities classified as “available-for-sale” are carried at fair value, and unrealized gains and losses on such securities, net of any deferred taxes, are reported as a separate component of accumulated other comprehensive income. The Company does not have any securities classified as “held-to-maturity” or “trading”. Fair value generally represents quoted market value prices for securities traded in the public marketplace or prices analytically determined using bid or closing prices for securities not traded in the public marketplace. Premiums and discounts on mortgage-backed securities and asset-backed securities are amortized or accrued using the constant yield method which considers anticipated prepayments at the date of purchase. To the extent that the estimated lives of such securities change as a result of changes in estimated prepayment rates, the adjustments are included in net investment income using the retrospective method. Realized investment gains or losses are determined on a specific identification basis. Interest income is recognized as earned, and dividend income is recognized on the ex-dividend date. The Company reviews its available-for-sale fixed maturities to determine whether any 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.
Bank Loan Participations	Bank Loan Participations Bank loan participations are managed by a specialized outside investment manager. The Company has elected the fair value option to account for bank loan participations. Under the fair value option, bank loan participations are measured at fair value, and changes in unrealized gains and losses in bank loan participations are reported in our Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) as net realized and unrealized gains (losses) on investments. Losses due to credit-related impairments on bank loan participations 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. Interest income is accrued on the unpaid principal balance. Discounts and premiums 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. Interest received on nonaccrual loans generally is reported as investment income. There were no bank loans on nonaccrual status at December 31, 2025 or 2024. 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.
Other Invested Assets	Other Invested Assets Other invested assets at December 31, 2025 and 2024 include the Company’s interests in private debt and equity investments. The investments are primarily focused in structured private credit, renewable energy, and limited partnerships. Equity interests in various limited liability companies (“LLCs”) and limited partnerships are accounted for under the equity method, as the Company has determined that the equity method best reflects its economic interest in the underlying equity investment.
Short-Term Investments	Short-Term Investments Short-term investments are carried at amortized cost, which approximates fair value. Short-term investments have maturities greater than three months but less than one year at the date of purchase.
Cash Equivalents	Cash Equivalents The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.
Restricted Cash Equivalents	Restricted Cash Equivalents The Company considers highly liquid investments with maturities of three months or less at the date of purchase that are segregated for a specific use to be restricted cash equivalents.
Direct Written Premiums	Direct Written Premiums Direct written premiums are earned on a pro rata basis over the terms of the policies, generally 12 months. The portion of premiums written applicable to the unexpired terms of the policies in force is recorded as unearned premiums. Policies are accounted for on an individual basis, with no aggregation by counterparty.
Premiums Receivable and Agents' Balances, Net	Premiums Receivable and Agents’ Balances, Net Premiums receivable and agents’ balances are carried at face value net of any allowance for credit losses. The allowance for credit losses represents the current estimate of expected credit losses based on the Company’s assessment of the collectability of receivables that are past due, historical collection percentages, and consideration of current economic conditions and expectations of future conditions that could affect ultimate collections. Receivables greater than 90 days past due were $17.0 million and $16.4 million at December 31, 2025 and 2024, respectively. The allowance for credit losses was $19.7 million and $22.3 million at December 31, 2025 and 2024, respectively. Credit loss expense was $442,000 for the year ended December 31, 2025, $6.9 million for the year ended December 31, 2024, and $2.8 million for the year ended December 31, 2023. Receivables written off against the allowance for credit losses totaled $3.0 million for the year ended December 31, 2025, $2.5 million for the year ended December 31, 2024, and $1.2 million for the year ended December 31, 2023. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs Costs which are incrementally or directly related to the successful acquisition of new or renewal insurance business are deferred. These deferred costs are primarily commissions to agents, premium taxes, and the portion of underwriting fixed compensation and payroll related fringe benefits directly related to an insurance contract that has been acquired, net of ceding commissions related to reinsurance ceded. Amortization of such policy acquisition costs is charged to expense in proportion to premium earned over the estimated policy life. To the extent that unearned premiums on existing policies are not adequate to cover projected related costs and expenses, deferred policy acquisition costs are charged to earnings. The Company considers anticipated investment income in determining whether a premium deficiency exists.
Reinsurance and Adjustable Features of Insurance and Reinsurance Contracts and Retroactive Reinsurance Accounting	Reinsurance and Adjustable Features of Insurance and Reinsurance Contracts Certain premiums and losses are ceded to other insurance companies under various excess of loss and quota-share reinsurance contracts. The Company enters into ceded reinsurance contracts to limit its exposure to large losses, to limit exposure on new lines of insurance written by the Company, and to provide additional capacity for growth. Premiums, commissions, and losses and loss adjustment expenses on reinsured business are accounted for on a basis consistent with that used in accounting for the original policies issued and the terms of the reinsurance contracts. Reinsurance recoverables and prepaid reinsurance premiums are reported as assets. The Company uses a provision matrix to calculate the allowance for credit losses on reinsurance recoverables by applying impairment rates based on historical loss data to similarly rated reinsurance companies based on the expected duration of the receivables. The Company also considers the expected impact of current and future expected economic conditions and adjusts estimates if needed based on an evaluation of these factors. The allowance for credit losses on reinsurance recoverables at December 31, 2025 and 2024 was $1.6 million and $1.2 million, respectively. Other amounts payable to reinsurers or receivable from reinsurers are netted where the right of offset exists. The Company receives ceding commissions in connection with certain ceded reinsurance. The ceding commissions are recorded as a reduction of other operating expenses. Certain reinsurance contracts include provisions that adjust premiums or acquisition expenses based upon the loss experience under the contracts. Premiums written and earned, as well as related acquisition expenses are recorded based upon the projected loss experience under the contracts. The Company’s Specialty Admitted Insurance segment writes insurance under specialty admitted fronting and program arrangements. The fronting and program arrangements may contain contractual provisions that adjust acquisition expenses based upon loss experience under the contracts. The specialty admitted fronting and program arrangements are significantly reinsured. These reinsurance contracts may also contain provisions that adjust premiums or acquisition expenses based upon the loss experience under the contracts. Premiums written and earned, as well as related acquisition expenses, are recorded based upon the projected loss experience under the contracts. Retroactive Reinsurance Accounting Loss portfolio transfers and adverse development covers are forms of reinsurance utilized by the Company to transfer losses and loss adjustment expenses and associated risk of adverse development on covered subject business for losses that have already occurred ("retroactive"), as defined in the respective agreements, to an assuming reinsurer in exchange for a reinsurance premium. The Company periodically reevaluates the remaining reserves subject to loss portfolio transfers and adverse development covers, and when recognized adverse prior year development on the subject business causes the cumulative amounts ceded under the agreements to exceed the consideration paid, the agreements move 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 agreements using the recovery method.
Other Income	Other Income Other income is principally comprised of broker incentive income in the Excess and Surplus Lines segment ($3.3 million, $5.4 million, and $1.3 million for the years ended December 31, 2025, 2024, and 2023, respectively) and fee income in the Specialty Admitted Insurance segment earned on policies for which the segment has no exposure to underwriting risk. Fee income of $2.4 million, $4.6 million, and $5.3 million is included in other income for the years ended December 31, 2025, 2024, and 2023, respectively. Fees are earned on a pro rata basis over the service period of the underlying business. Policies are accounted for on an individual basis, with no aggregation by counterparty.
Income Taxes	Income Taxes Deferred tax assets and deferred tax liabilities are provided for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of assets and liabilities and their respective U.S. tax basis. Deferred tax assets and liabilities are measured using enacted U.S. corporate tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance only when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized.
Goodwill	Goodwill Goodwill is tested annually for impairment in the fourth quarter of each calendar year, or more frequently if events or changes in circumstances indicate that the carrying amount of the Company’s reporting units, including goodwill, may exceed their fair values. The Company first assesses qualitative factors in determining whether it is necessary to perform the quantitative goodwill impairment test. If management determines that it is more likely than not that the fair value of a reporting unit is less than the carrying value based on qualitative factors then they will perform the quantitative goodwill impairment test. For the quantitative goodwill impairment testing, the fair value of the reporting units is determined using a combination of a market approach and an income approach which projects the future cash flows produced by the reporting units and discounts those cash flows to their present value. The projection of future cash flows is necessarily dependent upon assumptions on the future levels of income as well as business trends, prospects, market, and economic conditions. The results of the two approaches are weighted to determine the fair value of each reporting unit. When the fair value is less than the carrying value of the net assets of the reporting unit, including goodwill, an impairment loss is charged to operations. To determine the amount of any goodwill impairment, the implied fair value of reporting unit goodwill is compared to the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination is determined. That is, the fair value of a reporting unit is assigned to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.
Intangible Assets, Net	Intangible Assets, Net Intangible assets are initially recognized and measured at fair value. Specifically identified intangible assets with indefinite lives include trademarks and state insurance licenses and authorities. Other specifically identified intangible assets with lives ranging from 7.0 to 27.5 years represent relationships with brokers. These intangible assets are amortized on a straight-line basis over their estimated useful lives. Intangible assets with indefinite useful lives are reviewed for impairment at least annually. In evaluating whether there has been impairment to the intangible asset, management determines the fair value of the intangible asset and compares the resulting fair value to the carrying value of the intangible asset. If the carrying value exceeds the fair value, the intangible asset is written down to fair value, and the impairment is reported through earnings. The Company evaluates intangible assets with definite lives for impairment when impairment indicators are noted.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets with finite lives are tested for impairment whenever recognized events or changes in circumstances indicate the carrying value of these assets may not be recoverable. If indicators of impairment are present, fair value is calculated using estimated future cash flows expected to be generated from the use of those assets. An impairment loss is recognized only if the carrying amount of a long-lived asset or asset group is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. That assessment is based on the carrying amount of the asset or asset group at the date it is tested for recoverability. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset or asset group exceeds its fair value.
Property and Equipment, Net	Property and Equipment, Net Property and equipment, which is included in “other assets” in the accompanying consolidated balance sheets, is reported at cost less accumulated depreciation and is depreciated principally on a straight-line basis over the estimated useful lives of the depreciable assets, generally three years to ten years.
Reserve for Losses and Loss Adjustment Expenses	Reserve for Losses and Loss Adjustment Expenses The reserve for losses and loss adjustment expenses represents the estimated ultimate cost of all reported and unreported losses and loss adjustment expenses incurred and unpaid at the balance sheet date. The Company does not discount this reserve. The process of estimating the reserve for losses and loss adjustment expenses requires a high degree of judgment and is subject to a number of variables. The reserve for losses and loss adjustment expenses is estimated using individual case-basis valuations and statistical analyses. Those estimates are subject to the effects of trends in loss severity and frequency. The Company utilizes various actuarially-accepted reserving methodologies in determining expected outcomes for its reserves. These methodologies utilize various inputs, including management’s initial expected loss ratio (the ratio of losses and loss adjustment expenses incurred to net earned premiums), expected reporting patterns and payment patterns for losses and loss adjustment expenses (based on insurance industry data and the Company’s own experience), and the Company’s actual paid and reported losses and loss adjustment expenses. An internal actuary reviews these results and (after applying appropriate professional judgment and other actuarial techniques that are considered necessary) presents recommendations to the Company’s management. Management uses this information and its judgment to make decisions on the final recorded reserve for losses and loss adjustment expenses. Management believes that the use of judgment is necessary to arrive at a best estimate for the reserve for losses and loss adjustment expenses given the long-tailed nature of the business generally written by the Company and the limited operating experience of the fronting and program business in the Specialty Admitted Insurance segment. Judgment is also required to make actuarial adjustments, if needed, for changes in claims processing and case reserving that could cause current reported loss and paid loss development patterns to deviate from historical patterns. The Company believes that the insurance that it writes is subject to above-average variation in reserve estimates. The Excess and Surplus Lines market is subject to high policyholder turnover and changes in underlying mix of exposures. This turnover and change in underlying mix of exposures can cause actuarial estimates based on prior experience to be less reliable than estimates for more stable, admitted books of business. Catastrophes of significant magnitude, including hurricanes, earthquakes, and wildfires, involve complex coverage issues. In estimating the reserve for losses and loss adjustment expenses for these catastrophes, management uses case reserve estimates based on information obtained from site inspections by the Company’s adjustors and the terms of coverage provided in the policies. Management estimates reserves for incurred but not reported claims for these catastrophes using judgment based on an assessment of the Company’s property insurance exposures where the catastrophes occur and the Company’s progress in settling claims. Although management believes that the reserve for losses and loss adjustment expenses is reasonable, it is possible that the Company’s actual incurred losses and loss adjustment expenses will not develop in a manner consistent with the assumptions inherent in the determination of these reserves. Specifically, the Company’s actual ultimate loss ratio could differ from management’s initial expected loss ratio and/or the Company’s actual reporting patterns for losses could differ from the expected reporting patterns. Accordingly, the ultimate settlement of losses and the related loss adjustment expenses may vary significantly from the estimates included in the Company’s consolidated financial statements. These estimates are reviewed continually by management and are adjusted as necessary as experience develops or new information becomes known; such adjustments are included in current operations.
Stock Based Compensation	Share Based Compensation The Company expenses the fair value of stock equity awards over the vesting period of the award on a straight-line basis. Compensation cost for performance restricted stock units (“PRSU”) is based upon the probable outcome of performance conditions. The Black-Scholes-Merton option pricing model is used to value options granted (see Note 14). Forfeitures of share-based awards are recognized as they occur. As the share based compensation expense is incurred, a corresponding increase to additional paid-in capital in shareholders’ equity is recognized. Share based compensation expense is reflected in “other operating expenses” in the accompanying consolidated statements of income (loss) and comprehensive income (loss).
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 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 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.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share excludes dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the dilution that could occur if securities or other contracts to issue common shares were exercised or vested using the treasury stock method or converted into common shares under the if-converted method. When inclusion of potential common shares increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive, and the diluted net earnings or net loss per share is computed excluding these potential common shares.
Adopted and Prospective Accounting Standards	Adopted Accounting Standards The guidance in ASU 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures was designed to increase transparency about income tax information through improvements to the rate reconciliation and disclosure of income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024. The Company adopted the new standard effective with this Form 10-K by providing additional disclosures in Note 15. The new standard did not have a material impact on the Company's financial statements. No other accounting standards were adopted during the year ended December 31, 2025 that had a material impact on our financial statements. Prospective Accounting Standards The guidance in ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses requires additional, disaggregated disclosure around certain income statement expense line items. This ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on the disclosures in its financial statements. The guidance in ASU 2025-06, Intangibles-Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal -Use Software removes the concept of project stages and requires the capitalization of software costs when management has committed to funding the software project and it is probable that the project will be completed. This ASU is effective for fiscal years beginning after December 15, 2027, but early adoption is permitted as of the beginning of an annual reporting period. The Company is evaluating the impact of adopting this new guidance, but does not expect that the standard will have a material impact on our financial statements. There are no other prospective accounting standards which are expected to have a material impact on our financial statements subsequent to December 31, 2025.
Leases	Operating lease costs are primarily comprised of rental expense for operating leases. Rental expense is recognized on a straight line basis over the lease term and includes amortization of the right-of-use lease asset and imputed interest on the lease liability. Operating lease costs are included in other operating expenses in the Company's consolidated statements of income (loss) and comprehensive income (loss).

Accounting Policies (Policies)

Dec. 31, 2025

Basis of Presentation and Principles of Consolidation

The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), which vary in some respects from statutory accounting practices (“SAP”) which are prescribed or permitted by the various state insurance departments in the U.S. The accompanying consolidated financial statements include the accounts and operations of the Company and its subsidiaries. Intercompany transactions and balances have been eliminated.

Discontinued Operations

The results of operations of a component of the Company are reported in discontinued operations when certain criteria are met as of the date of disposal, or earlier if classified as held-for-sale. The Company determined that the sale of JRG Re, which closed on April 16, 2024, represented a strategic shift that had a major effect on the Company's operations. Accordingly, the results of JRG Re's operations have been presented as discontinued operations for all periods presented in this Annual Report on Form 10-K.

Estimates and Assumptions

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

Fixed Maturity and Equity Securities

Fixed maturity securities classified as “available-for-sale” are carried at fair value, and unrealized gains and losses on such securities, net of any deferred taxes, are reported as a separate component of accumulated other comprehensive income. The Company does not have any securities classified as “held-to-maturity” or “trading”.

Fair value generally represents quoted market value prices for securities traded in the public marketplace or prices analytically determined using bid or closing prices for securities not traded in the public marketplace.

Premiums and discounts on mortgage-backed securities and asset-backed securities are amortized or accrued using the constant yield method which considers anticipated prepayments at the date of purchase. To the extent that the estimated lives of

such securities change as a result of changes in estimated prepayment rates, the adjustments are included in net investment income using the retrospective method.

Realized investment gains or losses are determined on a specific identification basis. Interest income is recognized as earned, and dividend income is recognized on the ex-dividend date.

The Company reviews its available-for-sale fixed maturities to determine whether any 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.

Bank Loan Participations

Bank loan participations are managed by a specialized outside investment manager. The Company has elected the fair value option to account for bank loan participations. Under the fair value option, bank loan participations are measured at fair value, and changes in unrealized gains and losses in bank loan participations are reported in our Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) as net realized and unrealized gains (losses) on investments.

Losses due to credit-related impairments on bank loan participations 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.

Interest income is accrued on the unpaid principal balance. Discounts and premiums 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. Interest received on nonaccrual loans generally is reported as investment income. There were no bank loans on nonaccrual status at December 31, 2025 or 2024.

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.

Other Invested Assets

Other invested assets at December 31, 2025 and 2024 include the Company’s interests in private debt and equity investments. The investments are primarily focused in structured private credit, renewable energy, and limited partnerships. Equity interests in various limited liability companies (“LLCs”) and limited partnerships are accounted for under the equity method, as the Company has determined that the equity method best reflects its economic interest in the underlying equity investment.

Short-Term Investments

Short-term investments are carried at amortized cost, which approximates fair value. Short-term investments have maturities greater than three months but less than one year at the date of purchase.

Cash Equivalents

The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.

Restricted Cash Equivalents

The Company considers highly liquid investments with maturities of three months or less at the date of purchase that are segregated for a specific use to be restricted cash equivalents.

Direct Written Premiums

Direct written premiums are earned on a pro rata basis over the terms of the policies, generally 12 months. The portion of premiums written applicable to the unexpired terms of the policies in force is recorded as unearned premiums. Policies are accounted for on an individual basis, with no aggregation by counterparty.

Premiums Receivable and Agents' Balances, Net

Premiums Receivable and Agents’ Balances, Net

Premiums receivable and agents’ balances are carried at face value net of any allowance for credit losses. The allowance for credit losses represents the current estimate of expected credit losses based on the Company’s assessment of the collectability of receivables that are past due, historical collection percentages, and consideration of current economic conditions and expectations of future conditions that could affect ultimate collections. Receivables greater than 90 days past due were $17.0 million and $16.4 million at December 31, 2025 and 2024, respectively. The allowance for credit losses was $19.7 million and $22.3 million at December 31, 2025 and 2024, respectively. Credit loss expense was $442,000 for the year ended December 31, 2025, $6.9 million for the year ended December 31, 2024, and $2.8 million for the year ended December 31, 2023. Receivables written off against the allowance for credit losses totaled $3.0 million for the year ended December 31, 2025, $2.5 million for the year ended December 31, 2024, and $1.2 million for the year ended December 31, 2023. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

Deferred Policy Acquisition Costs

Costs which are incrementally or directly related to the successful acquisition of new or renewal insurance business are deferred. These deferred costs are primarily commissions to agents, premium taxes, and the portion of underwriting fixed compensation and payroll related fringe benefits directly related to an insurance contract that has been acquired, net of ceding commissions related to reinsurance ceded. Amortization of such policy acquisition costs is charged to expense in proportion to premium earned over the estimated policy life. To the extent that unearned premiums on existing policies are not adequate to cover projected related costs and expenses, deferred policy acquisition costs are charged to earnings. The Company considers anticipated investment income in determining whether a premium deficiency exists.

Reinsurance and Adjustable Features of Insurance and Reinsurance Contracts and Retroactive Reinsurance Accounting

Reinsurance and Adjustable Features of Insurance and Reinsurance Contracts

Certain premiums and losses are ceded to other insurance companies under various excess of loss and quota-share reinsurance contracts. The Company enters into ceded reinsurance contracts to limit its exposure to large losses, to limit exposure on new lines of insurance written by the Company, and to provide additional capacity for growth.

Premiums, commissions, and losses and loss adjustment expenses on reinsured business are accounted for on a basis consistent with that used in accounting for the original policies issued and the terms of the reinsurance contracts. Reinsurance recoverables and prepaid reinsurance premiums are reported as assets. The Company uses a provision matrix to calculate the allowance for credit losses on reinsurance recoverables by applying impairment rates based on historical loss data to similarly rated reinsurance companies based on the expected duration of the receivables. The Company also considers the expected impact of current and future expected economic conditions and adjusts estimates if needed based on an evaluation of these factors. The allowance for credit losses on reinsurance recoverables at December 31, 2025 and 2024 was $1.6 million and $1.2 million, respectively. Other amounts payable to reinsurers or receivable from reinsurers are netted where the right of offset exists. The Company receives ceding commissions in connection with certain ceded reinsurance. The ceding commissions are recorded as a reduction of other operating expenses.

Certain reinsurance contracts include provisions that adjust premiums or acquisition expenses based upon the loss experience under the contracts. Premiums written and earned, as well as related acquisition expenses are recorded based upon the projected loss experience under the contracts.

The Company’s Specialty Admitted Insurance segment writes insurance under specialty admitted fronting and program arrangements. The fronting and program arrangements may contain contractual provisions that adjust acquisition expenses based upon loss experience under the contracts. The specialty admitted fronting and program arrangements are significantly reinsured. These reinsurance contracts may also contain provisions that adjust premiums or acquisition expenses based upon the

loss experience under the contracts. Premiums written and earned, as well as related acquisition expenses, are recorded based upon the projected loss experience under the contracts.

Retroactive Reinsurance Accounting

Loss portfolio transfers and adverse development covers are forms of reinsurance utilized by the Company to transfer losses and loss adjustment expenses and associated risk of adverse development on covered subject business for losses that have already occurred ("retroactive"), as defined in the respective agreements, to an assuming reinsurer in exchange for a reinsurance premium. The Company periodically reevaluates the remaining reserves subject to loss portfolio transfers and adverse development covers, and when recognized adverse prior year development on the subject business causes the cumulative amounts ceded under the agreements to exceed the consideration paid, the agreements move 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 agreements using the recovery method.

Other Income

Other income is principally comprised of broker incentive income in the Excess and Surplus Lines segment ($3.3 million, $5.4 million, and $1.3 million for the years ended December 31, 2025, 2024, and 2023, respectively) and fee income in the Specialty Admitted Insurance segment earned on policies for which the segment has no exposure to underwriting risk. Fee income of $2.4 million, $4.6 million, and $5.3 million is included in other income for the years ended December 31, 2025, 2024, and 2023, respectively. Fees are earned on a pro rata basis over the service period of the underlying business. Policies are accounted for on an individual basis, with no aggregation by counterparty.

Income Taxes

Deferred tax assets and deferred tax liabilities are provided for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of assets and liabilities and their respective U.S. tax basis. Deferred tax assets and liabilities are measured using enacted U.S. corporate tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance only when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized.

Goodwill

Goodwill is tested annually for impairment in the fourth quarter of each calendar year, or more frequently if events or changes in circumstances indicate that the carrying amount of the Company’s reporting units, including goodwill, may exceed their fair values. The Company first assesses qualitative factors in determining whether it is necessary to perform the quantitative goodwill impairment test. If management determines that it is more likely than not that the fair value of a reporting unit is less than the carrying value based on qualitative factors then they will perform the quantitative goodwill impairment test. For the quantitative goodwill impairment testing, the fair value of the reporting units is determined using a combination of a market approach and an income approach which projects the future cash flows produced by the reporting units and discounts those cash flows to their present value. The projection of future cash flows is necessarily dependent upon assumptions on the future levels of income as well as business trends, prospects, market, and economic conditions. The results of the two approaches are weighted to determine the fair value of each reporting unit. When the fair value is less than the carrying value of the net assets of the reporting unit, including goodwill, an impairment loss is charged to operations. To determine the amount of any goodwill impairment, the implied fair value of reporting unit goodwill is compared to the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination is determined. That is, the fair value of a reporting unit is assigned to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.

Intangible Assets, Net

Intangible assets are initially recognized and measured at fair value. Specifically identified intangible assets with indefinite lives include trademarks and state insurance licenses and authorities. Other specifically identified intangible assets with lives ranging from 7.0 to 27.5 years represent relationships with brokers. These intangible assets are amortized on a straight-line basis over their estimated useful lives.

Intangible assets with indefinite useful lives are reviewed for impairment at least annually. In evaluating whether there has been impairment to the intangible asset, management determines the fair value of the intangible asset and compares the resulting fair value to the carrying value of the intangible asset. If the carrying value exceeds the fair value, the intangible asset is written down to fair value, and the impairment is reported through earnings. The Company evaluates intangible assets with definite lives for impairment when impairment indicators are noted.

Impairment of Long-Lived Assets

Long-lived assets with finite lives are tested for impairment whenever recognized events or changes in circumstances indicate the carrying value of these assets may not be recoverable. If indicators of impairment are present, fair value is calculated using estimated future cash flows expected to be generated from the use of those assets. An impairment loss is recognized only if the carrying amount of a long-lived asset or asset group is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. That assessment is based on the carrying

amount of the asset or asset group at the date it is tested for recoverability. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset or asset group exceeds its fair value.

Property and Equipment, Net

Property and equipment, which is included in “other assets” in the accompanying consolidated balance sheets, is reported at cost less accumulated depreciation and is depreciated principally on a straight-line basis over the estimated useful lives of the depreciable assets, generally three years to ten years.

Reserve for Losses and Loss Adjustment Expenses

The reserve for losses and loss adjustment expenses represents the estimated ultimate cost of all reported and unreported losses and loss adjustment expenses incurred and unpaid at the balance sheet date. The Company does not discount this reserve. The process of estimating the reserve for losses and loss adjustment expenses requires a high degree of judgment and is subject to a number of variables. The reserve for losses and loss adjustment expenses is estimated using individual case-basis valuations and statistical analyses. Those estimates are subject to the effects of trends in loss severity and frequency.

The Company utilizes various actuarially-accepted reserving methodologies in determining expected outcomes for its reserves. These methodologies utilize various inputs, including management’s initial expected loss ratio (the ratio of losses and loss adjustment expenses incurred to net earned premiums), expected reporting patterns and payment patterns for losses and loss adjustment expenses (based on insurance industry data and the Company’s own experience), and the Company’s actual paid and reported losses and loss adjustment expenses. An internal actuary reviews these results and (after applying appropriate professional judgment and other actuarial techniques that are considered necessary) presents recommendations to the Company’s management. Management uses this information and its judgment to make decisions on the final recorded reserve for losses and loss adjustment expenses. Management believes that the use of judgment is necessary to arrive at a best estimate for the reserve for losses and loss adjustment expenses given the long-tailed nature of the business generally written by the Company and the limited operating experience of the fronting and program business in the Specialty Admitted Insurance segment. Judgment is also required to make actuarial adjustments, if needed, for changes in claims processing and case reserving that could cause current reported loss and paid loss development patterns to deviate from historical patterns. The Company believes that the insurance that it writes is subject to above-average variation in reserve estimates. The Excess and Surplus Lines market is subject to high policyholder turnover and changes in underlying mix of exposures. This turnover and change in underlying mix of exposures can cause actuarial estimates based on prior experience to be less reliable than estimates for more stable, admitted books of business.

Catastrophes of significant magnitude, including hurricanes, earthquakes, and wildfires, involve complex coverage issues. In estimating the reserve for losses and loss adjustment expenses for these catastrophes, management uses case reserve estimates based on information obtained from site inspections by the Company’s adjustors and the terms of coverage provided in the policies. Management estimates reserves for incurred but not reported claims for these catastrophes using judgment based on an assessment of the Company’s property insurance exposures where the catastrophes occur and the Company’s progress in settling claims.

Although management believes that the reserve for losses and loss adjustment expenses is reasonable, it is possible that the Company’s actual incurred losses and loss adjustment expenses will not develop in a manner consistent with the assumptions inherent in the determination of these reserves. Specifically, the Company’s actual ultimate loss ratio could differ from management’s initial expected loss ratio and/or the Company’s actual reporting patterns for losses could differ from the expected reporting patterns. Accordingly, the ultimate settlement of losses and the related loss adjustment expenses may vary significantly from the estimates included in the Company’s consolidated financial statements. These estimates are reviewed continually by management and are adjusted as necessary as experience develops or new information becomes known; such adjustments are included in current operations.

Stock Based Compensation

Share Based Compensation

The Company expenses the fair value of stock equity awards over the vesting period of the award on a straight-line basis. Compensation cost for performance restricted stock units (“PRSU”) is based upon the probable outcome of performance conditions. The Black-Scholes-Merton option pricing model is used to value options granted (see Note 14). Forfeitures of share-based awards are recognized as they occur. As the share based compensation expense is incurred, a corresponding increase to additional paid-in capital in shareholders’ equity is recognized. Share based compensation expense is reflected in “other operating expenses” in the accompanying consolidated statements of income (loss) and comprehensive income (loss).

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 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 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.

Earnings (Loss) Per Share

Basic earnings (loss) per share excludes dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the dilution that could occur if securities or other contracts to issue common shares were exercised or vested using the treasury stock method or converted into common shares under the if-converted method. When inclusion of potential common shares increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive, and the diluted net earnings or net loss per share is computed excluding these potential common shares.
