Domiciled in the U.K. since 2022, Syndicate 3456 is authorized to underwrite under the Lloyd’s syndicate-in-a-box model. The ordinary shares of GLRE are listed on Nasdaq Global Select Market under the symbol “GLRE.” Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of GLRE and the consolidated financial statements of its wholly-owned subsidiaries, and all significant intercompany transactions and balances have been eliminated on consolidation. Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the presentation of the current consolidated financial statements. The Company has reported separately the foreign exchange gains (losses) from “ Other income ” in the consolidated statements of operations.

The Company has also included the foreign exchange gains (losses) as part of the net change in working capital in the consolidated statements of cash flows. Further, the Company combined “Other assets, excluding depreciation” and “Other liabilities” and presented the sum as “Other items, net” in the consolidated statements of cash flows. These changes in presentation in the consolidated statements of cash flows have resulted in no change to the previously reported net cash provided by (used in) operating activities. Tabular dollar are in thousands, with the exception of per share amounts or otherwise noted. All amounts are reported in U.S. dollars.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES The Company’s significant accounting policies are as follows: Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from these estimates. The Company’s principal estimates include: • loss and loss adjustment expense reserves; • premiums written and earned and related premium receivable, net of expected credit losses; • reinsurance recoverable on unpaid losses and loss adjustment expenses, including expected credit losses; and • valuation of investments, including impairments. Investments Investment in related party investment fund The Company records its investment in the related party investment fund based on fair value using the net asset value practical expedient, with the Company’s share of the fund’s net income (loss) reported as “ Income (loss) from investment in related party investment fund ” in the consolidated statements of operations. Other investments The Company’s other investments include short-term investments and private investments and unlisted equity securities without readily determinable fair values. Short-term investments are measured at amortized cost, which approximates fair value. These include certificate of deposit and other financial instruments with original maturities greater than three months but less than one year. The Company measures its private investments and unlisted equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from identical or similar investments of the same issuers (the “measurement alternative”), with such changes recognized in “ Net investment income (loss) ” in the consolidated statements of operations. The Company considers the need for impairment on a by-investment basis based on certain indicators. Under the measurement alternative, the Company makes two types of valuation adjustments: • When the Company observes an orderly transaction of an investee’s identical or similar equity securities, the Company adjusts the carrying value based on the observable price as of the transaction date. Once the Company records such an adjustment, the investment is considered an “asset measured at fair value on a nonrecurring basis.” • If the Company determines that the investment is impaired and the fair value is less than its carrying value, it writes down the investment to its fair value. Once the Company records such an adjustment, the investment is considered an “asset measured at fair value on a nonrecurring basis.” Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term, highly liquid investments and certificates of deposit with original maturity dates of three months or less. Restricted cash and cash equivalents are presented separately in the consolidated balance sheets. Premium Revenue Recognition The Company writes excess of loss contracts and quota share contracts and estimates the ultimate premiums for the contract period. The Company bases these estimates on actuarial pricing models and information received from ceding companies. For excess of loss contracts, the Company writes the total ultimate estimated premiums at the contract’s inception. For quota share contracts, the Company writes premiums in the same periods in which the underlying insurance contracts are written, based on cession statements from cedents. The Company typically receives these statements monthly or quarterly, depending on the terms specified in each contract. For any reporting lag, the Company estimates premiums written based on the portion of the estimated ultimate premiums relating to the risks bound during the lag period. For multi-year contracts, reinsurance premiums are recorded at the inception of the contract based on management’s best estimate of total premiums to be received. Premiums are recognized on an annual basis for multi-year contracts where the cedants have the ability to unilaterally commute or cancel coverage within the term of the contract. Management regularly reviews premium estimates. Such review includes the Company’s experience with the ceding companies, managing general underwriters, familiarity with each market, the timing of the reported information, a comparison of reported premiums to expected ultimate premiums, along with a review of the aging and collection of premiums. Management evaluates the appropriateness of the premium estimates on the basis of these reviews and records any adjustments to these estimates in the period in which they are determined. Changes in premium estimates, including premium receivable on both excess of loss and quota share contracts, are not unusual and may result in significant adjustments in any period. A portion of amounts included in “ Reinsurance balances receivable ” in the consolidated balance sheets represent estimated premiums written, net of commissions and brokerage, that are not currently due based on the terms of the underlying contracts. Additional premiums due on a contract with no remaining coverage period are earned in full when written. Certain contracts allow for reinstatement premiums in the event of a loss. Reinstatement premiums are written and earned when a triggering loss event occurs. Premiums written are generally recognized as earned over the contract period in proportion to the risk covered. Unearned premiums represent the unexpired portion of reinsurance provided. Reinsurance Premiums Ceded The Company reduces the risk of future losses on business assumed by reinsuring certain risks and exposures with other reinsurers (referred to as “retrocessionaires”). The Company remains liable to the extent that any retrocessionaire fails to meet its obligations and to the extent the Company does not hold sufficient security for its unpaid obligations. Ceded premiums are written during the period in which the risks incept and the associated expense is recognized over the contract period in proportion to the protection provided. Unearned premiums ceded represent the unexpired portion of reinsurance obtained. Acquisition Costs Policy acquisition costs vary with, and are directly related to, the successful production of new and renewal business and consist principally of commissions, taxes, and brokerage expenses. The Company presents acquisition costs incurred on reinsurance assumed net of commissions earned on reinsurance ceded. However, if the sum of a contract’s expected losses and loss expenses and deferred acquisition costs exceeds associated unearned premiums and expected investment income, a premium deficiency is determined to exist. In this event, the Company writes off deferred acquisition costs to the extent necessary to eliminate the premium deficiency. If the premium deficiency exceeds deferred acquisition costs, the Company accrues a liability for the deficiency. The Company did not recognize any premium deficiency adjustments during the periods presented. Policy acquisition costs also include profit commissions, which the Company recognized on a basis consistent with its estimate of losses and loss expenses. Loss and Loss Adjustment Expense Reserves and Recoverable The Company’s loss and loss adjustment expense reserves (“LAE”) are composed of: ● case reserves for loss and LAE resulting from claims notified to the Company by its clients; and ● reserves for estimated loss and LAE incurred by insureds and reinsureds but not yet reported to the insurer or reinsurer (“IBNR”), including unknown future developments on loss and LAE that are known to the insurer or reinsurer. The Company estimates these reserves based on reports from ceding companies, industry data, and historical experience analyzed using standard actuarial and statistical techniques. The analysis includes assessing currently available data, predictions of future developments, estimates of future trends, and other factors. These estimates are reviewed by the Company’s reserving committee at least quarterly and adjusted as necessary. The final settlement of losses may vary, perhaps materially, from the reserves recorded. The Company recognizes all adjustments to the estimates in the period they are determined. U.S. GAAP does not permit establishing loss reserves, which include case reserves and IBNR loss reserves, until the occurrence of an event that may give rise to a claim. As a result, only loss reserves applicable to losses incurred up to the reporting date are established. There is no allowance for the establishment of loss reserves to account for expected future loss events. The “ Loss and loss adjustment expenses recoverable ” in the consolidated balance sheets represents the amounts due from retrocessionaires for unpaid loss and LAE on retrocession agreements. Ceded IBNR recoverable amounts are estimated based on the Company’s actuarial estimates. These estimates are reviewed periodically and adjusted when deemed necessary. The Company may be unable to recover the loss and LAE recoverable amounts due as a result of the retrocessionaires’ inability to pay. The Company regularly evaluates the financial condition of its retrocessionaires and calculates an allowance for expected credit losses (see “Reinsurance Assets ” below). For losses stemming from exposure to natural perils, loss reserves are generally established based on loss payments and case reserves reported by clients when, and if, received. Estimates for IBNR losses are added to the case reserves as the Company deems appropriate. To establish catastrophe IBNR loss estimates, the Company uses estimates communicated by ceding companies, industry data and information, knowledge of the business written, and management’s judgment. For contracts without significant exposure to natural perils, initial reserves for each contract are determined based on a combination of (i) the pricing analysis performed prior to binding the contract; (ii) the underwriter’s detailed knowledge of the cedent, its operations and future business plans; and (iii) the professional judgment and recommendation of the Chief Actuary. In the pricing analysis, the Company utilizes information from the client and industry data. This information typically includes, but is not limited to, data related to premiums, losses, exposure, business mix, industry performance, and associated trends covering as much history as deemed appropriate. The level of detail within the data obtained varies greatly depending on the underlying contract, line of business, client, and coverage provided. In all cases, the Company requests each client to provide data for each reporting period, which, depending on the contract, could be on a monthly or quarterly basis. The terms and conditions of each contract specify the data reporting requirements. Generally, the Company obtains regular updates of premium and loss-related information for the current and historical periods and utilizes them to update the initially expected loss ratio. There may be a lag between (i) claims being reported by the underlying insured to the Company’s cedent and (ii) claims being reported by the Company’s cedent to the Company. This lag may impact the Company’s loss reserve estimates. Client reports have pre-determined due dates (for example, fifteen days after each month-end). The timing of the reporting requirements is designed so that the Company receives premium and loss information as soon as practicable once the client has closed its books. Accordingly, there should be a short lag in such reporting. Additionally, most contracts that have the potential for large single-event losses have provisions that such loss notifications are provided to the Company immediately upon the occurrence of an event. Once the updated information is received, the Company uses various standard actuarial methods for its quarterly analysis. Such methods typically include the following: ● Paid loss development method: Ultimate losses are estimated by calculating past paid loss development factors and applying them to exposure periods with further expected paid loss development. This method assumes that losses are paid in a consistent pattern. It provides an objective test of reported loss projections because paid losses contain no reserve estimates. ● Reported loss development method: Ultimate losses are estimated by calculating past reported loss development factors and applying them to exposure periods with further expected reported loss development. This method incorporates changes in payments and case reserves. ● Expected loss ratio method: Ultimate losses are estimated by multiplying earned premiums by an expected loss ratio. The expected loss ratio is often determined using industry data, historical company data, past pricing or reserving analysis performed, and actuarial judgment. This method is typically used for lines of business and contracts where there are no (or insignificant) historical losses or where past loss experience is not considered applicable to the current period. ● Bornhuetter-Ferguson paid loss method: Ultimate losses are estimated by modifying expected loss ratios to the extent losses paid to date differ from what would have been expected based upon the selected paid loss development pattern. This method avoids some distortions that could result from a large development factor being applied to a small base of paid losses to calculate ultimate losses. ● Bornhuetter-Ferguson reported loss method: Ultimate losses are estimated by modifying expected loss ratios to the extent losses reported to date differ from what would have been expected based upon the selected reported loss development pattern. This method avoids some distortions that could result from a large development factor being applied to a small base of reported losses to calculate ultimate losses. ● Frequency / Severity method: Ultimate losses are estimated by multiplying the ultimate number of claims (i.e., the frequency multiplied by the exposure base) by the estimated average cost per claim (i.e., the severity). This approach enables trends and patterns in the rates of claims emergence (i.e., reporting) and settlement (i.e., closure) and the average cost of claims to be analyzed separately. In addition, the Company may supplement its analysis with other reserving methodologies that it deems relevant to specific contracts. For each contract, the Company utilizes reserving methodologies it considers appropriate to calculate a best estimate of reserves. Whether the Company uses a single methodology or a combination depends upon the portfolio segment being analyzed and the actuary’s judgment. The Company’s reserving methodology does not require a fixed weighting of the various methods used. Certain methods are considered more appropriate than others depending on the type, structure, age, maturity, and duration of the expected losses on the contract. For example, the Bornhuetter-Ferguson reported loss method might be more appropriate than a paid loss development method for relatively new contracts that have experienced little paid loss development. The Company’s gross aggregate reserves are the sum of the best estimate reserves of all portfolio exposures. Generally, IBNR loss reserves are calculated by estimating the ultimate incurred losses and subtracting cumulative paid claims and case reserves. Each quarter, the Company’s Reserving Committee, led by the Chief Actuary, meets to assess the adequacy of our loss reserves based on the reserve analysis and recommendations prepared by the Company’s reserving department. The Company does not typically experience material claims processing backlogs, although such backlogs may occur following a major catastrophic event. At December 31, 2023, and 2022, the Company did not have a material backlog in its claims processing. The Company did not make any significant changes to the actuarial methodology or assumptions relating to its loss and loss adjustment expense reserves for the years presented in the consolidated financial statements. Reinsurance Assets The Company calculates an allowance for expected credit losses for its reinsurance balances receivable and loss and LAE recoverable by applying a Probability of Default (“PD”) / Loss Given Default (“LGD”) model. The PD / LGD approach considers the Company’s collectibility history on its reinsurance assets and representative external loss history. In calculating the probability of default, the Company also considers the estimated duration of its reinsurance assets. The Company evaluates each counterparty’s creditworthiness based on credit ratings that independent agencies assign to the counterparty. The Company manages its credit risk in its reinsurance assets by transacting only with insurers and reinsurers that it considers financially sound. Credit ratings of the counterparties are forward-looking and consider various economic scenarios. The Company's evaluation of the required allowance for reinsurance balances receivable and loss and LAE recoverable considers the current economic environment as well as potential macroeconomic developments. For its retrocessional counterparties that are unrated, the Company may hold collateral in the form of funds withheld, trust accounts, or irrevocable letters of credit. In evaluating credit risk associated with reinsurance balances receivable, the Company considers its right to offset loss obligations against premiums receivable. The Company regularly evaluates its net credit exposure to assess the ability of cedents and retrocessionaires to honor their respective obligations. Deposit Assets and Liabilities The Company applies deposit accounting to reinsurance contracts that do not transfer sufficient insurance risk to merit reinsurance accounting. Under deposit accounting, the Company recognizes an asset or liability based on its paid or received consideration. The deposit asset or liability balance is subsequently adjusted using the interest method with the corresponding income and expense recorded in the Company’s consolidated statements of operations under “ Other income (expense) ” and “ Deposit interest expense ,” respectively. The Company records deposit assets and liabilities in its consolidated balance sheets in “ Reinsurance balances receivable ” and “ Reinsurance balances payable ,” respectively. At December 31, 2023, deposit assets and liabilities were $0.9 million and $5.2 million, respectively (December 31, 2022: $3.1 million and $10.7 million, respectively). Net investment income (loss) The Company records interest income and interest expense on an accrual basis. Any realized and unrealized gains or losses from other investments are determined on the basis of the specific identification method (by reference to cost or amortized cost, as appropriate). Additionally, net investment income (loss) includes realized and unrealized gains (losses) on derivative instruments. Other Income (Expense), net In connection with the Company’s participation interest in Lloyd’s syndicates, the Lloyd’s syndicates invest a portion of the premiums withheld in investment funds and fixed-maturity securities. The Company records its share of income (or expense) from these assets as other income (expense) as reported by the syndicates on a quarterly lag basis due to the timing of the availability of these quarterly financial reports. Share-Based Compensation The Company recognizes share-based compensation costs based on the fair value at the award’s grant date. The Company measures compensation for restricted shares and restricted stock units (“RSUs”) based on the price of the Company’s common shares at the grant date. For restricted shares and RSUs with service and performance vesting conditions, the expense is recognized based on management’s estimate of the probability of the performance conditions being achieved based on historical results and expectations of future results. If the Company expects to meet the performance conditions, it attributes the expense to the period the requisite service is rendered. For restricted shares and RSUs with only service vesting conditions, the Company recognizes the associated expense on a straight-line basis over the vesting period, net of any estimated or expected forfeitures. The forfeiture rate is estimated based on the Company’s historical actual forfeitures relating to restricted shares and RSUs granted to employees. The forfeiture rate is reviewed annually and adjusted as necessary. The Company applies no forfeiture rate to restricted shares granted to directors, which vest over a maximum twelve-month period. Determining the fair value of share purchase options at the grant date requires significant estimation and judgment. The Company uses the Black-Scholes option-pricing model to assist in the calculation of fair value for share purchase options. The model requires estimating various inputs such as the term, forfeiture and dividend rates, and expected volatility. In determining the grant date fair value, the Company uses the entire ten-year life of the options as the estimated term and assumes no forfeitures and no dividends paid during the life of the options. The Company bases its estimate of expected volatility on the daily historical trading data of the Company’s ordinary shares from the date they commenced trading (May 24, 2007) to the grant date. For share purchase options issued under the employee stock incentive plan, the compensation cost is calculated and recognized over the vesting periods on a graded vesting basis. Convertible Notes Prior to the adoption of Accounting Standards Update (“ASU”) 2020-06 in January 2022, “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”),” the Company determined that the senior convertible notes’ cash conversion option represented an embedded derivative and bifurcated it from the underlying contract for financial reporting purposes. For the debt component, the Company recorded a liability equivalent to the present value of comparable debt without the conversion features at the time of issuance. The remainder of the proceeds, which represented the embedded derivative, was included in “ Additional paid-in capital ” in the consolidated balance sheets. Upon adoption of ASU 2020-06, U.S. GAAP no longer permits entities to bifurcate embedded conversion features from the underlying contract. Therefore, effective January 1, 2022, the Company no longer presents the embedded conversion features separately in equity; instead, the Company’s senior convertible debt is presented as a single liability in the Company’s consolidated balance sheet. The adoption of ASU 2020-06 resulted in a decrease in the Company’s opening shareholders’ equity of $2.5 million, with a corresponding increase in the carrying value of the senior convertible notes. Costs incurred in issuing the convertible notes consisted primarily of underwriting, legal, accounting, and printing fees. These costs are amortized over the term of the debt and are included in “ Interest expense ” in the consolidated statements of operations. Foreign Exchange The reporting and functional currency of the Company and all its significant subsidiaries is the U.S. dollar. The Company records foreign currency transactions at the exchange rates in effect on the transaction date. Monetary assets and liabilities in foreign currencies are converted at the exchange rate in effect at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currencies are carried at their historical exchange rates. Derivative instruments The Company recognizes derivative financial instruments in the consolidated balance sheets at their fair values. The Company’s derivatives do not qualify as hedges for financial reporting purposes. The Company records the associated assets and liabilities in its consolidated balance sheets on a gross basis. The Company does not offset these balances against collateral pledged or received. Other Assets The Company’s other assets consist primarily of prepaid expenses, right-of-use lease assets, derivative assets, taxes recoverable, and deferred tax assets. Other Liabilities The Company’s other liabilities consist primarily of accruals for legal and other professional fees, employee bonuses and severances, taxes payable, derivative liabilities, and lease liabilities. Comprehensive Income (Loss) The Company has no comprehensive income or loss other than the net income or loss disclosed in the consolidated statements of operations. Earnings (Loss) Per Share The Company has issued unvested restricted stock awards, some of which contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid. These awards are considered “participating securities” for the purposes of calculating earnings (loss) per share. Basic earnings per share is calculated on the basis of the weighted average number of ordinary shares and participating securities outstanding during the period. Diluted earnings (or loss) per share includes the dilutive effect, if any, of the following: • Restricted Stock Units (“RSUs”) issued that convert to ordinary shares upon vesting; • Unvested restricted share awards which are not considered “participating securities”; • Additional potential ordinary shares issuable when in-the-money stock options are exercised, determined using the treasury stock method; • For periods prior to January 1, 2022, those ordinary shares with the potential to be issued in connection with convertible notes and other such convertible instruments, determined using the treasury stock method; and • Effective January 1, 2022, the dilutive effect of the convertible notes calculated using the if-converted method. Under the if-converted method, the convertible notes are assumed to be converted at the beginning of the period. The resulting common shares are included in the denominator of the diluted net income per common share calculation. Interest expense related to the convertible notes incurred in the period is added back to the numerator for purposes of the if-converted calculation. Diluted earnings (or loss) per share contemplates a conversion to ordinary shares of all convertible instruments only if they are dilutive. In the event of a net loss, all RSUs, stock options, shares potentially issuable in connection with convertible notes, and participating securities are excluded from the calculation of both basic and diluted loss per share as their inclusion would be anti-dilutive. Taxation The Company records current and deferred income taxes based on enacted tax laws and rates applicable in the relevant jurisdiction in the period in which the tax becomes accruable or realizable. Deferred income taxes are provided for all temporary differences between the bases of assets and liabilities reported in the consolidated balance sheets and those reported in the various jurisdictional tax returns. The Company records a valuation allowance to the extent that the Company considers it more likely than not that all or a portion of the deferred tax asset will not be realized in the future. Other than this valuation allowance, the Company has not taken any income tax positions subject to significant uncertainty that is reasonably likely to have a material impact on the Company. Segment Information Operating segments are based on the internal information that the Chief Operating Decision Maker uses for allocating the Company’s resources and assessing its performance. The Company has one operating segment, Property and Casualty Reinsurance. Recent Accounting Pronouncements Recently Issued Accounting Standards Not Yet Adopted On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures . The new ASU requires incremental disclosures related to a public entity’s reportable segments but does not change the definition of a segment, the method for determining segments, or the criteria for aggregating operating segments into reportable segments. This new guidance is effective for the Company’s 2024 year-end financial statements, and should be adopted retrospectively unless impracticable. Early adoption is permitted. On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic (740) - Improvements to Income Tax Disclosures . The amendments in this Update provide more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. This ASU is effective for the Company’s 2024 year-end financial statements. As the above ASUs relate solely to financial statement disclosures, the adoption of these ASUs will not impact the Company’s financial condition, results of operations, or cash flows. Recently Issued Accounting Standards Adopted There are none that would be relevant and material to the Company.

INVESTMENT IN RELATED PARTY INV

Equity Method Investments and Joint Ventures [Abstract]
INVESTMENT IN RELATED PARTY INVESTMENT FUND	INVESTMENT IN RELATED PARTY INVESTMENT FUND The Company has entered into the Second Amended and Restated Exempted Limited Partnership Agreement (the “SILP LPA”) of Solasglas Investments, LP (“SILP”), with DME Advisors II, LLC (“DME II”), as General Partner, Greenlight Re, and GRIL, (together, the “GLRE Limited Partners”). SILP has entered into a SILP investment advisory agreement (“IAA”) with DME Advisors. LP (“DME Advisors”), pursuant to which DME Advisors is the investment manager for SILP. DME II and DME Advisors are related to the Company, and each is an affiliate of David Einhorn, Chairman of the Company’s Board of Directors (the “Chairman”). At December 31, 2023, the SILP LPA included the following proviso: “The Investment Portfolio of each Partner will not exceed the product of (a) such Partner’s surplus (Greenlight Re Surplus or GRIL Surplus, as the case may be) multiplied by (b) the Investment Cap (60%), and the General Partner will designate any portion of a Partner’s Investment Portfolio as Designated Securities to effectuate such limit.” The Company has concluded that SILP qualifies as a variable interest entity (“VIE”) under U.S. GAAP. In assessing its interest in SILP, the Company noted the following: • DME II serves as SILP’s general partner and has the power to appoint the investment manager. The Company does not have the power to appoint, change or replace the investment manager or the general partner except “for cause.” Neither of the GLRE Limited Partners can participate in the investment decisions of SILP as long as SILP adheres to the investment guidelines provided within the SILP LPA. For these reasons, the GLRE Limited Partners are not considered to have substantive participating rights or kick-out rights. • DME II holds an interest in excess of 10% of SILP’s net assets, which the Company considers to represent an obligation to absorb losses and a right to receive benefits of SILP that are significant to SILP. Consequently, the Company has concluded that DME II’s interests, not the Company’s, meet both the “power” and “benefits” criteria associated with VIE accounting guidance. Therefore DME II is SILP’s primary beneficiary. The Company presents its investment in SILP in its consolidated balance sheets in the caption “Investment in related party investment fund.” The Company’s maximum exposure to loss relating to SILP is limited to the net asset value of the GLRE Limited Partners’ investment in SILP. At December 31, 2023, the net asset value of the GLRE Limited Partners’ investment in SILP was $258.9 million (December 31, 2022: $178.2 million), representing 72.7% (December 31, 2022: 69.3%) of SILP’s total net assets. DME II held the remaining 27.3% (December 31, 2022: 30.7%) of SILP’s total net assets. The investment in SILP is recorded at the GLRE Limited Partners’ share of the net asset value of SILP as reported by SILP’s third-party administrator. The GLRE Limited Partners can redeem their assets from SILP for operational purposes by providing 3 business days’ notice to DME II. At December 31, 2023, the majority of SILP’s long investments were composed of cash and publicly-traded equity securities, which could be readily liquidated to meet the GLRE Limited Partners’ redemption requests. The Company’s share of the change in the net asset value of SILP for the years ended December 31, 2023, 2022, and 2021, was $28.7 million, $54.8 million, and $18.1 million, respectively, and shown in the caption “Income from investment in related party investment fund” in the Company’s consolidated statements of operations. The Company has determined that for its fiscal year ended December 31, 2023, the Company’s investment in SILP met at least one of the conditions of a significant subsidiary under SEC’s Regulation S-X, Rule 3-09. Accordingly, the audited financial statements for SILP have been attached as an exhibit (Exhibit 99.1) to this Form 10-K. The summarized financial statements of SILP are presented below.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair Value Hierarchy The fair value of a financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants. Assets and liabilities measured at fair value are categorized based on the extent to which the inputs are observable in the market. The categorization of financial instruments within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) defined as follows: • Level 1: Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. • Level 2: Observable inputs other than prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated with observable market data. • Level 3: Unobservable inputs supported by little or no market activity and significant to the fair value of the assets and liabilities. The term “unobservable inputs” includes certain pricing models, discounted cash flow methodologies, and similar techniques. There have been no material change in the Company’s valuation techniques, nor have there been any transfers between Level 1 and Level 2, or Level 2 and Level 3 for the years presented in these consolidated financial statements. Assets measured at fair value on a nonrecurring basis At December 31, 2023, the Company held $61.3 million (2022: $53.6 million) of private investments and unlisted equities measured at fair value on a nonrecurring basis. At December 31, 2023, the Company held $9.9 million (2022: $8.9 million) of private investments and unlisted equities measured at cost. The Company classifies these investments as Level 3 within the fair value hierarchy. The following table summarizes the periods between the most recent fair value measurement dates and December 31, 2023, for the private and unlisted equities measured at fair value on a nonrecurring basis: Less than 6 months 6 to 12 months Over 1 year Total Fair values measured on a nonrecurring basis $ 26,438 $ 1,361 $ 33,490 $ 61,289 Assets measured at fair value on a recurring basis Derivative financial instruments The Company uses interest rate swaps in connection with its risk management activities to hedge 50% of the interest rate risk relating to the outstanding Term Loans (see Note 9). The interest rate swaps are carried at fair value and are determined using a market approach valuation technique based on significant observable market inputs from third-party pricing vendors. Accordingly, the interest rates swaps are classified as Level 2 within the fair value hierarchy. These derivative instruments are not designated as accounting hedges under U.S. GAAP. For the year ended December 31, 2023, the Company recognized unrealized loss for the above derivatives of $0.6 million (2022: $nil), which is included in “ Other liabilities ” in the consolidated balance sheets, in “ Interest expense ” in the consolidated statements of operations, and in “ Net realized and unrealized losses on derivatives ” in the consolidated statements of cash flows. Financial Instruments Disclosed, But Not Carried, at Fair Value The carrying value of debt and convertible debt securities within “ Other Investments ” (see “Private investments and unlisted equity securities without readily determinable fair values” above) and certificates of deposit with original maturities of one year or less approximates their fair values. The Company classifies these assets as Level 2 within the fair value hierarchy. At December 31, 2023, the carrying values of the Term Loans approximate their fair values.

The magnitude and volume of losses arising from these events is inherently uncertain and, consequently, actual losses for these events may ultimately differ, potentially materially, from current estimates. During the year ended December 31, 2023, the Company recognized CAT loss, net of reinsurance, of $28.8 million for current year CAT loss events, driven mainly by the U.S. severe storms and the Mexican state-owned oil platform fire loss. This was partially offset by $10.7 million of net favorable prior year CAT development. For the year ended December 31, 2022, the Company recognized current year CAT loss of $39.7 million driven primarily by $13.6 million from the Russian-Ukrainian conflict and $19.5 million from hurricane Ian. This was partially offset by $5.0 million net favorable prior year CAT development. Prior Year Reserve Development Year ended December 31, 2023 During the year ended December 31, 2023, the Company experienced $11.2 million in net adverse development on prior year loss and LAE reserves. This was comprised of $39.8 million of reserve strengthening on casualty, workers’ compensation and auto classes of business due to current economic and social inflation trends (various underwriting years); homeowners business primary due to the deterioration in the CAT loss estimate relating to Winter Storm Elliott (2022 underwriting year), coupled with a final claim settlement on a professional liability contract (2008 underwriting year). This was partially offset by $28.6 million favorable loss development from property catastrophe events and better than expected loss emergence for mortgage, marine and energy, and specialty contracts from underwriting years 2020-2022. See the loss development tables by lines of business below under “Disclosure about Short-Duration Contracts” for more information on prior year loss reserve development. Year ended December 31, 2022 During the year ended December 31, 2022, the Company experienced $0.1 million in net adverse development on prior year loss and LAE reserves. This was comprised of $21.9 million of reserve strengthening on motor, health, casualty, professional liability, and workers’ compensation contracts from underwriting years 2014-2021, coupled with higher claim settlements on certain general liability contracts for 2015-2016 underwriting years. This was partially offset by $21.8 million favorable loss development from various pre-2021 years’ property catastrophe events, including COVID-19, and better than expected loss emergence for mortgage business (from 2017-2020 underwriting years), a multi-line combined workers’ compensation and commercial packages contract across multiple underwriting years, coupled with favorable development on a whole account contract (2020 underwriting year). Year ended December 31, 2021 During the year ended December 31, 2021, the Company experienced $14.1 million in net favorable development on prior year loss and LAE reserves. This was comprised of $37.4 million favorable loss development from better-than-expected loss emergence for motor, mortgage, and various specialty contracts (including crop, space, and marine and energy) from underwriting years 2015-2018, coupled with a multi-line contract that incepted in 2019. This was partially offset by $23.3 million adverse loss development primarily due to reserve strengthening on multi-line casualty, general liability and workers’ compensation contracts from underwriting years 2014-2019. Disclosures about Short-Duration Contracts The Company has one operating segment, Property & Casualty Reinsurance, and categorizes its business as Property, Casualty, and Other. The Company’s loss development tables presented below have been disaggregated by lines of business for the years ended from December 31, 2014, through 2023. For purposes of the loss development tables, the property business has been further disaggregated into "Property" and "Motor - Physical Damage." The casualty category has been disaggregated into "General Liability," "Motor Liability," "Professional Liability," and "Workers' Compensation." Contracts that cover more than one line of business, including Lloyd’s business, are grouped as "Multi-line." Other specialty business, including aviation, crop, cyber, and energy, which are individually insignificant to the Company’s overall business, have been grouped as "Other." As the Company’s accident and health business has become immaterial in recent years, the Company has grouped accident and health business with “Other” during 2023. Additionally, the Company has elected to present the loss development table for “Marine” separately from “Other” due to its growth in 2023. As a result, the historical incurred and paid claims development presented in the tables below differ from those disclosed in previously issued financial statements. Conforming changes were also made to the table above presenting t he changes in the outstanding loss and loss adjustment expense reserves for health claims as part of the “Consolidated” table for the years ended December 31, 2022, and 2021. The amounts shown in “ Net loss and loss adjustment expenses incurred ” in the consolidated statements of operations and the allocation between “Current year” and “Prior years” are unaffected by these revisions. For each category, the following tables present the incurred and paid claims development at December 31, 2023, net of retrocession, and the total of incurred but not reported liabilities plus expected development on reported claims included within the net incurred claims amount. The tables below present incurred and paid claims development for the years ended December 31, 2014 to 2022. They are presented as unaudited supplementary information.

As a result, all prior year information has been restated to reflect December 31, 2023, foreign exchange rates. This treatment prevents changes in foreign currency exchange rates from distorting the claims development between the years presented. For assumed contracts, the Company does not generally receive claims information by accident year from the ceding insurers but instead receives claims information by the treaty year of the contract. Claims reported by the ceding insurer to the Company may have the covered losses occurring in an accident year other than the treaty year. Some incurred and paid claims have been allocated to the accident years for the loss development tables based on the proportion of premiums earned for each contract during such accident year. For example, a one-year quota-share reinsurance treaty incepting on October 1, 2020 (with underlying policies each having a one-year duration) would have a 24-month period over which the premiums would be earned. Therefore, claims would be allocated to accident years 2020, 2021 and 2022 based on the proportion of the premiums earned during each accident year. For illustration of this contract, any claims reported during 2020 would be allocated to the 2020 accident year. For losses reported during 2021, the claims would be allocated between 2020 and 2021 based on the percentage of premiums earned during 2020 and 2021. Similarly, for losses reported during 2022 and thereafter, the losses would be allocated to the 2020, 2021 and 2022 accident years based on the proportion of premiums earned during each of those years. However, natural catastrophes and certain other large losses are addressed separately and are assigned to the accident year in which they occurred. The reconciliation of the net incurred and paid claims development tables to the liability for claims and claim adjustment expenses in the consolidated balance sheet is as follows: December 31, 2023 Net outstanding liabilities Multiline $ 247,929 General Liability 74,853 Motor Casualty 22,622 Motor Property 2,972 Property 48,914 Professional Liability 15,767 Workers' Compensation 55,792 Financial Lines 56,202 Marine 27,150 Other 77,092 Liabilities for claims and claims adjustment expenses, net of reinsurance 629,293 Add: Reinsurance recoverable on unpaid claims 25,687 Add: Unallocated claims adjustment expenses 6,087 Add: Allowance for credit losses 487 Total gross liabilities for unpaid claims and claim adjustment expense $ 661,554 The average historical annual percentage payout of net incurred claims (excluding health) at December 31, 2023, is as follows: Years 1 2 3 4 5 6 7 8 9 10 (Unaudited - Supplementary Information) Multiline 11.2 % 17.3 % 16.0 % 11.6 % 9.8 % 9.9 % 9.2 % 8.1 % 4.7 % 2.2 % General Liability 4.7 % 13.6 % 13.1 % 12.5 % 18.2 % 27.5 % 6.9 % 3.0 % 0.4 % 0.1 % Motor Casualty 49.5 % 35.8 % 7.7 % 3.6 % 1.5 % 0.9 % 0.8 % 0.2 % — % — % Motor Property 53.3 % 40.8 % 4.9 % 1.0 % — % — % — % — % — % — % Property 49.0 % 34.4 % 8.2 % 3.2 % 2.7 % 0.9 % 1.0 % 0.5 % 0.1 % — % Professional Liability 2.7 % 9.8 % 14.3 % 12.7 % 8.7 % 7.3 % 5.6 % 2.3 % 2.6 % 34.0 % Workers' Compensation 30.9 % 35.2 % 20.4 % 9.2 % 3.0 % 0.9 % 0.2 % 0.2 % — % — % Financial Lines 18.5 % 33.8 % 23.6 % 12.0 % 4.1 % 3.7 % 1.7 % 1.5 % 1.1 % — % Marine 4.3 % 25.2 % 40.0 % 2.3 % 11.3 % 1.7 % 15.2 % — % — % — % Other 19.7 % 27.2 % 7.7 % 9.3 % 7.7 % 7.1 % 7.1 % 6.9 % 7.3 % — % The historical annual percentage payout pattern for health claims is excluded from the table above because health claims have short settlement periods, and including it would skew the results presented.

Reinsurance Disclosures [Abstract]
RETROCESSION	RETROCESSION From time to time, the Company purchases retrocessional coverage for one or more of the following reasons: to manage its overall exposure, reduce its net liability on individual risks, obtain additional underwriting capacity, and balance its underwriting portfolio. The Company records loss and loss adjustment expenses recoverable from retrocessionaires as assets. The following table provides a breakdown of ceded reinsurance: Year ended December 31 2023 2022 2021 Gross ceded premiums $ 42,762 $ 33,429 $ 41 Earned ceded premiums $ 43,653 $ 15,318 $ — Loss and loss adjustment expenses ceded $ 25,554 $ 6,615 $ (12) Retrocession contracts do not relieve the Company from its obligations to its cedents. Failure of retrocessionaires to honor their obligations could result in losses to the Company. The following table shows a breakdown of losses recoverable on a gross and net of collateral basis: December 31, 2023 December 31, 2022 Gross Net of Collateral (1) Gross Net of Collateral (1) A- or better by A.M. Best $ 8,767 $ 8,767 $ 3,797 $ 3,792 Not rated 17,407 2,432 9,504 286 Total before provision 26,174 $ 11,199 $ 13,301 $ 4,078 Provision for credit losses (487) (62) Total loss and loss adjustment expenses recoverable, net $ 25,687 $ 13,239 (1) Collateral is in the form of cash, letters of credit, funds withheld, and/or cash collateral held in trust accounts. This excludes any excess collateral in order to disclose the aggregate net exposure for each retrocessionaire. At December 31, 2023, we had 3 reinsurers (2022: 4) that accounted for 10% or more each of the total loss and loss adjustment expenses recoverable, net, for an aggregate gross amount of $20.4 million (2022: $11.1 million).

DEBT AND CREDIT FACILITIES	DEBT AND CREDIT FACILITIES Debt Obligations The following table summarizes the Company’s outstanding debt obligations. December 31, 2023 December 31, 2022 Term loans $ 74,062 $ — Senior convertible notes — 79,610 Total principal amount 74,062 79,610 Accrued interest payable — 1,331 Less: deferred financing costs (781) (407) Total debt $ 73,281 $ 80,534 Term Loans On June 16, 2023, the Company entered into a Credit Agreement (the “Credit Agreement”) with a group of banks (the “Banks”), for which CIBC Bank USA is acting as administrative agent. The Credit Agreement provides, subject to certain customary conditions, for a delayed draw term loan facility (the “Loan Facility”), in an aggregate amount of $75.0 million. Outstanding loans (“Term Loans”) under the Facility will (i) amortize in equal quarterly installments in an aggregate annual amount equal to 5.0% of the Term Loans and (ii) accrue interest at a rate equal to an adjusted term Secured Overnight Financing Rate (“SOFR”) plus 3.5% per annum. The Company posted $10.0 million of collateral as security for the Loan Facility. The Loan Facility matures on August 1, 2026. During the year ended December 31, 2023, the Company borrowed $75.0M from the Loan Facility of which $63.4 million was used to repay all of the outstanding Convertible Senior Notes (see below), with the remaining proceeds for general corporate purposes. The Company also made $0.9 million partial repayment on the Term Loans. The interest rate on the outstanding Terms Loans was 8.9% at December 31, 2023. To manage interest rate risk, the Company hedged 50% of the floating interest rate on the Term Loans (see Note 6). The Company was in compliance with all covenants relating to the Loan Facility at December 31, 2023. Senior Convertible Notes On August 7, 2018, the Company issued $100.0 million of senior unsecured convertible notes (the “Convertible Notes”), with a maturity date of August 1, 2023. The Convertible Notes paid interest at 4.0%, payable semi-annually on February 1 and August 1 of each year beginning February 1, 2019. The conversion price was $17.19 per ordinary share of the Company. During the year ended December 31, 2023 the Company repurchased and canceled $17.5 million (2022: $20.4 million) of the Convertible Notes, respectively, resulting in realized gains of $0.3 million (2022: $0.3 million), which is included in “ Other income (expense), net ” in the consolidated statements of operations. As noted above, the Company fully repaid the remaining outstanding Convertible Notes on August 1, 2023, from the proceeds of the new Term Loans. Financing Costs The Company incurred $0.9 million of issuance costs relating to the Credit Agreement, which are deferred and amortized through the maturity of the Loan Facility. The remaining unamortized deferred financing costs are reported separately in the above table. For the year ended December 31, 2023, the Company recognized interest expense of $5.3 million (2022: $4.2 million, 2021: $6.3 million) relating to the total debt, which included the interest coupon, the amortization of issuance costs and the change in fair value of the interest rate swap (see Note 6) . Credit Facilities At December 31, 2023, the Company had the following letter of credit (“LOC”) facilities: Capacity LOCs issued Termination Date Citibank Europe plc ("Citi LOC") 1 $ 289,000 $ 276,756 August 20, 2024 CIBC Bank USA ("CIBC LOC") 200,000 13,903 December 21, 2024 $ 489,000 $ 290,659 1) Includes $14.0 million of uncommitted capacity. The above LOCs issued are cash collateralized (see Note 5). The LOC facilities are subject to various customary affirmative, negative and financial covenants. At December 31, 2023, the Company was in compliance with all LOC facilities covenants. Citi LOC The Citi LOC facility automatically renews each year unless terminated by either party subject to a 120 days notice prior to termination date. CIBC LOC On December 22, 2023, through a subsidiary, the Company entered into a credit agreement with CIBC Bank USA for a $200.0 million committed LOC facility (the “CIBC LOC Facility”), with a $30.0 million sublimit for unsecured LOCs (the “CIBC Revolving Credit Facility”). Loans made under the CIBC Revolving Credit Facility, solely for supporting unsecured LOCs, will accrue interest at a rate of base rate plus 2.5% per annum in the event that the beneficiary draws down on an unsecured LOC and the Company does not provide cash collateral within the stipulated period. The CIBC LOC Facility is subject to an automatic extension of one year without prior written notice by the Company. The CIBC Revolving Credit Facility expires after one year.

SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION On July 25, 2023, at the Company’s Annual General Meeting the shareholders approved the Greenlight Capital Re, Ltd. 2023 Omnibus Incentive Plan, or the 2023 Incentive Plan. The 2023 Incentive Plan replaces the Greenlight Capital Re, Ltd. Amended and Restated 2004 Stock Incentive Plan, or the 2004 Stock Incentive Plan. The aggregate number of ordinary shares that are available to be delivered pursuant to awards granted under the 2023 Incentive Plan is equal to the sum of (i) 2,000,000 shares, and (ii) any shares that remained or otherwise become available under the 2004 Stock Incentive Plan as of July 25, 2023. If, after July 25, 2023, any award granted under the 2023 Incentive Plan or the 2004 Stock Incentive Plan is forfeited or otherwise expires, terminates or is canceled , then the number of ordinary shares subject to such award that were not issued shall become available for issuance under the 2023 Incentive Plan. The 2023 Incentive Plan is administered by the Compensation Committee of the Board of Directors. At December 31, 2023, 3,296,771 (2022: 2,011,426) ordinary shares remained available for future issuance under the Company’s 2023 Incentive Plan. Under this plan, the Company is authorized to issue restricted shares, RSUs, and stock options. Share-based awards contain restrictions relating to vesting (service-based and/or performance-based), forfeiture in the event of termination of employment, transferability, and other matters. Employee and Director Restricted Shares The following table summarizes the activity for unvested outstanding restricted share awards: Performance Restricted Shares Service Restricted Shares Number of Weighted Number of Weighted Balance at December 31, 2021 193,149 $ 10.10 753,407 $ 8.68 Granted 601,213 6.82 356,422 7.02 Vested — — (268,457) 9.38 Forfeited — — (8,476) 7.67 Balance at December 31, 2022 794,362 $ 7.62 832,896 7.76 Granted 357,766 10.84 242,957 10.58 Vested — — (599,942) 8.74 Forfeited (109,440) 9.37 (56,307) 8.44 Balance at December 31, 2023 1,042,688 $ 9.94 419,604 $ 9.18 For the year ended December 31, 2023, the Company issued to non-employee directors an aggregate of 65,394 (2022: 107,763) restricted ordinary shares as part of their remuneration for services to the Company (included in “Service Restricted Shares” column in the above table). They will vest on the earlier of (i) the first anniversary of the date of the share issuance and (ii) the Company’s next annual general meeting, subject to the grantee’s continued service with the Company. For the year ended December 31, 2023, the Company granted to employees (i) 357,766 (2022: 601,213) restricted shares with both performance and service-based vesting conditions (“Performance RSs”) and (ii) 177,563 (2022: 248,659) restricted shares with only service-based vesting conditions (“Service RSs”). Most of these Service RSs vest evenly each year on January 1, subject to the grantee’s continued service with the Company. If performance goals are achieved, the Performance RSs will cliff vest at the end of a three-year performance period within a range of 25% and 100% of the awarded Performance RSs, with a target of 50%. Prior to fiscal year 2021, the Company issued ordinary shares to the Chief Executive Officer (“CEO”) pursuant to the Company’s stock incentive plan (“CEO RSs”). These shares contain performance and service conditions and certain restrictions relating to, among other things, vesting, forfeiture in the event of termination of the CEO’s employment, and transferability. The CEO RSs cliff vest five years after the date of issuance, subject to the performance condition being met and the CEO’s continued service with the Company. At December 31, 2023, there were 162,489 non-vested CEO RSs with a weighted average grant date fair value of $9.00 per share. As the performance conditions associated with these restricted shares have not been met, the Company recognized no compensation cost relating to the unvested CEO RSs for the years ended December 31, 2023, 2022, and 2021. During the year ended December 31, 2023, the Company modified certain share-based awards previously granted to the CEO in connection with the Separation Agreement (see Note 15), resulting in an incremental share-based compensation charge of $1.5 million (see below “Stock Compensation Expense”). At December 31, 2023, there was $3.0 million (2022: $3.3 million) of unrecognized compensation cost relating to non-vested restricted shares (excluding the above CEO RSs), which the Company expects to recognize over a weighted-average period of 1.4 years (2022: 1.4 years). For the year ended December 31, 2023, the total fair value of restricted shares vested was $5.2 million (2022: $2.5 million).

From 2022, the Service RSUs vest evenly over three years on January 1, subject to the grantee’s continued service with the Company. If performance goals are achieved, the Performance RSUs will cliff vest at the end of a three-year performance period within a range of 25% and 100% of the awarded Performance RSUs, with a target of 50%. At December 31, 2023, the total compensation cost related to non-vested RSUs not yet recognized was $0.4 million (2022: $0.6 million), which the Company expects to recognize over a weighted-average period of 1.5 years (2022: 1.6 years).

The statutory capital and surplus and required minimum statutory capital and surplus of the Company’s most significant regulated reinsurance operations are detailed below: Cayman Islands Ireland At December 31, 2023 2022 2023 2022 Statutory capital and surplus 569,044 $ 474,985 58,721 68,881 Required statutory capital surplus 256,586 226,507 39,367 41,859 Excess statutory capital 312,458 $ 248,478 19,354 $ 27,022 The statutory net income for the Company’s most significant regulated reinsurance operations were as follows: Greenlight Re GRIL Year ended December 31, 2023 $ 85,464 $ 11,479 Year ended December 31, 2022 $ 32,290 $ 4,612 Year ended December 31, 2021 $ 15,912 $ 3,800 Cayman Islands Greenlight Re is subject to the Cayman Islands’ Insurance (Capital and Solvency) (Classes B, C, and D Insurers) Regulations, (2018 Revision) (the “Insurance Regulations”). Under this Insurance Regulations, Greenlight Re is required to maintain minimum statutory capital and surplus equal to the greater of: a) the Minimum Capital Requirement of $50.0 million and b) the Prescribed Capital Requirement (“PCR”) as defined in the Insurance Regulations. Greenlight Re is not required to prepare statutory financial statements for filing with CIMA. There were no material differences between Greenlight Re’s GAAP capital, surplus, and net income and its statutory capital, surplus, and net income at December 31, 2023 and 2022, and for the years then ended. Any dividends declared and paid from Greenlight Re to the Company requires CIMA’s approval. During the year ended December 31, 2023, $8.3 million of dividends (2022: $60.1 million, 2021: $4.0 million) were declared or paid by Greenlight Re to the Company. The dividends were approved by CIMA and resulted in the return of additional share capital to the Company. The dividends were used primarily to repurchase and repay the Company’s Convertible Notes (see Note 9). At December 31, 2023, $312.5 million (2022: $248.5 million) of Greenlight Re’s capital and surplus was available for distribution as dividends. Ireland Effective January 1, 2016, the Company’s Irish subsidiary (GRIL) is obligated to maintain at all times the Minimum Capital Requirement (“Irish MCR”) and the Solvency Capital Requirement (“SCR”) as calculated by reference to Solvency II definition. There were no material differences between the statutory financial statements and statements prepared in accordance with U.S. GAAP for GRIL at December 31, 2023 and 2022, and for the years then ended. The amount of dividends that GRIL is permitted to distribute is limited to its retained earnings. The Central Bank of Ireland has powers to intervene if a dividend payment were to breach regulatory capital requirements. At December 31, 2023 and 2022, none of GRIL’s capital and surplus was available for distribution as dividends. Lloyd’s of London The Company operates in the Lloyd’s market through its corporate member, GCM, which provides 100% of Syndicate 3456’s capital support. Syndicate 3456 is managed by a third party managing agency. GCM and Syndicate 3456 are bound by the rules of Lloyd’s, which are prescribed by Bye-laws and Requirements made by the Council of Lloyd’s under powers conferred by the Lloyd’s Act 1982. These rules prescribe members’ membership subscription, the level of their contributions to the Lloyd’s Central Fund and the assets they must deposit with Lloyd’s in support of their underwriting. Further, the Council of Lloyd’s has broad powers to sanctions breaches of its rules, including the power to restrict or prohibit a member’s participation on Lloyd’s syndicates. The underwriting capacity of a member of Lloyd’s must be supported by providing a deposit, known as “Funds at Lloyds” or “FAL”, in the form of cash, certain investment securities, or letters of credit. The FAL is not available for distributions for the payment of dividends or for working capital requirements. Further, corporate members may also be required to maintain funds under the control of Lloyd’s in excess of their capital requirements and such funds also may not be available for distribution for the payment of dividends. The amount of FAL for Syndicate 3456 is determined by Lloyd’s and is based on Syndicate 3456’s solvency and capital requirement based on an internal capital model.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from these estimates. The Company’s principal estimates include: • loss and loss adjustment expense reserves; • premiums written and earned and related premium receivable, net of expected credit losses; • reinsurance recoverable on unpaid losses and loss adjustment expenses, including expected credit losses; and • valuation of investments, including impairments.
Investments and Financial Instruments, Net investment income (loss)	Investments Investment in related party investment fund The Company records its investment in the related party investment fund based on fair value using the net asset value practical expedient, with the Company’s share of the fund’s net income (loss) reported as “ Income (loss) from investment in related party investment fund ” in the consolidated statements of operations. Other investments The Company’s other investments include short-term investments and private investments and unlisted equity securities without readily determinable fair values. Short-term investments are measured at amortized cost, which approximates fair value. These include certificate of deposit and other financial instruments with original maturities greater than three months but less than one year. The Company measures its private investments and unlisted equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from identical or similar investments of the same issuers (the “measurement alternative”), with such changes recognized in “ Net investment income (loss) ” in the consolidated statements of operations. The Company considers the need for impairment on a by-investment basis based on certain indicators. Under the measurement alternative, the Company makes two types of valuation adjustments: • When the Company observes an orderly transaction of an investee’s identical or similar equity securities, the Company adjusts the carrying value based on the observable price as of the transaction date. Once the Company records such an adjustment, the investment is considered an “asset measured at fair value on a nonrecurring basis.” • If the Company determines that the investment is impaired and the fair value is less than its carrying value, it writes down the investment to its fair value. Once the Company records such an adjustment, the investment is considered an “asset measured at fair value on a nonrecurring basis.” Net investment income (loss) The Company records interest income and interest expense on an accrual basis. Any realized and unrealized gains or losses from other investments are determined on the basis of the specific identification method (by reference to cost or amortized cost, as appropriate). Additionally, net investment income (loss) includes realized and unrealized gains (losses) on derivative instruments.
Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term, highly liquid investments and certificates of deposit with original maturity dates of three months or less. Restricted cash and cash equivalents are presented separately in the consolidated balance sheets.
Premium Revenue Recognition	Premium Revenue Recognition The Company writes excess of loss contracts and quota share contracts and estimates the ultimate premiums for the contract period. The Company bases these estimates on actuarial pricing models and information received from ceding companies. For excess of loss contracts, the Company writes the total ultimate estimated premiums at the contract’s inception. For quota share contracts, the Company writes premiums in the same periods in which the underlying insurance contracts are written, based on cession statements from cedents. The Company typically receives these statements monthly or quarterly, depending on the terms specified in each contract. For any reporting lag, the Company estimates premiums written based on the portion of the estimated ultimate premiums relating to the risks bound during the lag period. For multi-year contracts, reinsurance premiums are recorded at the inception of the contract based on management’s best estimate of total premiums to be received. Premiums are recognized on an annual basis for multi-year contracts where the cedants have the ability to unilaterally commute or cancel coverage within the term of the contract. Management regularly reviews premium estimates. Such review includes the Company’s experience with the ceding companies, managing general underwriters, familiarity with each market, the timing of the reported information, a comparison of reported premiums to expected ultimate premiums, along with a review of the aging and collection of premiums. Management evaluates the appropriateness of the premium estimates on the basis of these reviews and records any adjustments to these estimates in the period in which they are determined. Changes in premium estimates, including premium receivable on both excess of loss and quota share contracts, are not unusual and may result in significant adjustments in any period. A portion of amounts included in “ Reinsurance balances receivable ” in the consolidated balance sheets represent estimated premiums written, net of commissions and brokerage, that are not currently due based on the terms of the underlying contracts. Additional premiums due on a contract with no remaining coverage period are earned in full when written. Certain contracts allow for reinstatement premiums in the event of a loss. Reinstatement premiums are written and earned when a triggering loss event occurs. Premiums written are generally recognized as earned over the contract period in proportion to the risk covered. Unearned premiums represent the unexpired portion of reinsurance provided.
Reinsurance Premiums Ceded	Reinsurance Premiums Ceded The Company reduces the risk of future losses on business assumed by reinsuring certain risks and exposures with other reinsurers (referred to as “retrocessionaires”). The Company remains liable to the extent that any retrocessionaire fails to meet its obligations and to the extent the Company does not hold sufficient security for its unpaid obligations. Ceded premiums are written during the period in which the risks incept and the associated expense is recognized over the contract period in proportion to the protection provided. Unearned premiums ceded represent the unexpired portion of reinsurance obtained. Reinsurance Assets The Company calculates an allowance for expected credit losses for its reinsurance balances receivable and loss and LAE recoverable by applying a Probability of Default (“PD”) / Loss Given Default (“LGD”) model. The PD / LGD approach considers the Company’s collectibility history on its reinsurance assets and representative external loss history. In calculating the probability of default, the Company also considers the estimated duration of its reinsurance assets. The Company evaluates each counterparty’s creditworthiness based on credit ratings that independent agencies assign to the counterparty. The Company manages its credit risk in its reinsurance assets by transacting only with insurers and reinsurers that it considers financially sound. Credit ratings of the counterparties are forward-looking and consider various economic scenarios. The Company's evaluation of the required allowance for reinsurance balances receivable and loss and LAE recoverable considers the current economic environment as well as potential macroeconomic developments. For its retrocessional counterparties that are unrated, the Company may hold collateral in the form of funds withheld, trust accounts, or irrevocable letters of credit. In evaluating credit risk associated with reinsurance balances receivable, the Company considers its right to offset loss obligations against premiums receivable. The Company regularly evaluates its net credit exposure to assess the ability of cedents and retrocessionaires to honor their respective obligations.
Acquisition Costs	Acquisition Costs Policy acquisition costs vary with, and are directly related to, the successful production of new and renewal business and consist principally of commissions, taxes, and brokerage expenses. The Company presents acquisition costs incurred on reinsurance assumed net of commissions earned on reinsurance ceded. However, if the sum of a contract’s expected losses and loss expenses and deferred acquisition costs exceeds associated unearned premiums and expected investment income, a premium deficiency is determined to exist. In this event, the Company writes off deferred acquisition costs to the extent necessary to eliminate the premium deficiency. If the premium deficiency exceeds deferred acquisition costs, the Company accrues a liability for the deficiency. The Company did not recognize any premium deficiency adjustments during the periods presented. Policy acquisition costs also include profit commissions, which the Company recognized on a basis consistent with its estimate of losses and loss expenses.
Loss and Loss Adjustment Expense Reserves and Recoverable	Loss and Loss Adjustment Expense Reserves and Recoverable The Company’s loss and loss adjustment expense reserves (“LAE”) are composed of: ● case reserves for loss and LAE resulting from claims notified to the Company by its clients; and ● reserves for estimated loss and LAE incurred by insureds and reinsureds but not yet reported to the insurer or reinsurer (“IBNR”), including unknown future developments on loss and LAE that are known to the insurer or reinsurer. The Company estimates these reserves based on reports from ceding companies, industry data, and historical experience analyzed using standard actuarial and statistical techniques. The analysis includes assessing currently available data, predictions of future developments, estimates of future trends, and other factors. These estimates are reviewed by the Company’s reserving committee at least quarterly and adjusted as necessary. The final settlement of losses may vary, perhaps materially, from the reserves recorded. The Company recognizes all adjustments to the estimates in the period they are determined. U.S. GAAP does not permit establishing loss reserves, which include case reserves and IBNR loss reserves, until the occurrence of an event that may give rise to a claim. As a result, only loss reserves applicable to losses incurred up to the reporting date are established. There is no allowance for the establishment of loss reserves to account for expected future loss events. The “ Loss and loss adjustment expenses recoverable ” in the consolidated balance sheets represents the amounts due from retrocessionaires for unpaid loss and LAE on retrocession agreements. Ceded IBNR recoverable amounts are estimated based on the Company’s actuarial estimates. These estimates are reviewed periodically and adjusted when deemed necessary. The Company may be unable to recover the loss and LAE recoverable amounts due as a result of the retrocessionaires’ inability to pay. The Company regularly evaluates the financial condition of its retrocessionaires and calculates an allowance for expected credit losses (see “Reinsurance Assets ” below). For losses stemming from exposure to natural perils, loss reserves are generally established based on loss payments and case reserves reported by clients when, and if, received. Estimates for IBNR losses are added to the case reserves as the Company deems appropriate. To establish catastrophe IBNR loss estimates, the Company uses estimates communicated by ceding companies, industry data and information, knowledge of the business written, and management’s judgment. For contracts without significant exposure to natural perils, initial reserves for each contract are determined based on a combination of (i) the pricing analysis performed prior to binding the contract; (ii) the underwriter’s detailed knowledge of the cedent, its operations and future business plans; and (iii) the professional judgment and recommendation of the Chief Actuary. In the pricing analysis, the Company utilizes information from the client and industry data. This information typically includes, but is not limited to, data related to premiums, losses, exposure, business mix, industry performance, and associated trends covering as much history as deemed appropriate. The level of detail within the data obtained varies greatly depending on the underlying contract, line of business, client, and coverage provided. In all cases, the Company requests each client to provide data for each reporting period, which, depending on the contract, could be on a monthly or quarterly basis. The terms and conditions of each contract specify the data reporting requirements. Generally, the Company obtains regular updates of premium and loss-related information for the current and historical periods and utilizes them to update the initially expected loss ratio. There may be a lag between (i) claims being reported by the underlying insured to the Company’s cedent and (ii) claims being reported by the Company’s cedent to the Company. This lag may impact the Company’s loss reserve estimates. Client reports have pre-determined due dates (for example, fifteen days after each month-end). The timing of the reporting requirements is designed so that the Company receives premium and loss information as soon as practicable once the client has closed its books. Accordingly, there should be a short lag in such reporting. Additionally, most contracts that have the potential for large single-event losses have provisions that such loss notifications are provided to the Company immediately upon the occurrence of an event. Once the updated information is received, the Company uses various standard actuarial methods for its quarterly analysis. Such methods typically include the following: ● Paid loss development method: Ultimate losses are estimated by calculating past paid loss development factors and applying them to exposure periods with further expected paid loss development. This method assumes that losses are paid in a consistent pattern. It provides an objective test of reported loss projections because paid losses contain no reserve estimates. ● Reported loss development method: Ultimate losses are estimated by calculating past reported loss development factors and applying them to exposure periods with further expected reported loss development. This method incorporates changes in payments and case reserves. ● Expected loss ratio method: Ultimate losses are estimated by multiplying earned premiums by an expected loss ratio. The expected loss ratio is often determined using industry data, historical company data, past pricing or reserving analysis performed, and actuarial judgment. This method is typically used for lines of business and contracts where there are no (or insignificant) historical losses or where past loss experience is not considered applicable to the current period. ● Bornhuetter-Ferguson paid loss method: Ultimate losses are estimated by modifying expected loss ratios to the extent losses paid to date differ from what would have been expected based upon the selected paid loss development pattern. This method avoids some distortions that could result from a large development factor being applied to a small base of paid losses to calculate ultimate losses. ● Bornhuetter-Ferguson reported loss method: Ultimate losses are estimated by modifying expected loss ratios to the extent losses reported to date differ from what would have been expected based upon the selected reported loss development pattern. This method avoids some distortions that could result from a large development factor being applied to a small base of reported losses to calculate ultimate losses. ● Frequency / Severity method: Ultimate losses are estimated by multiplying the ultimate number of claims (i.e., the frequency multiplied by the exposure base) by the estimated average cost per claim (i.e., the severity). This approach enables trends and patterns in the rates of claims emergence (i.e., reporting) and settlement (i.e., closure) and the average cost of claims to be analyzed separately. In addition, the Company may supplement its analysis with other reserving methodologies that it deems relevant to specific contracts. For each contract, the Company utilizes reserving methodologies it considers appropriate to calculate a best estimate of reserves. Whether the Company uses a single methodology or a combination depends upon the portfolio segment being analyzed and the actuary’s judgment. The Company’s reserving methodology does not require a fixed weighting of the various methods used. Certain methods are considered more appropriate than others depending on the type, structure, age, maturity, and duration of the expected losses on the contract. For example, the Bornhuetter-Ferguson reported loss method might be more appropriate than a paid loss development method for relatively new contracts that have experienced little paid loss development. The Company’s gross aggregate reserves are the sum of the best estimate reserves of all portfolio exposures. Generally, IBNR loss reserves are calculated by estimating the ultimate incurred losses and subtracting cumulative paid claims and case reserves. Each quarter, the Company’s Reserving Committee, led by the Chief Actuary, meets to assess the adequacy of our loss reserves based on the reserve analysis and recommendations prepared by the Company’s reserving department. The Company does not typically experience material claims processing backlogs, although such backlogs may occur following a major catastrophic event. At December 31, 2023, and 2022, the Company did not have a material backlog in its claims processing. The Company did not make any significant changes to the actuarial methodology or assumptions relating to its loss and loss adjustment expense reserves for the years presented in the consolidated financial statements.
Reinsurance Assets	Reinsurance Premiums Ceded The Company reduces the risk of future losses on business assumed by reinsuring certain risks and exposures with other reinsurers (referred to as “retrocessionaires”). The Company remains liable to the extent that any retrocessionaire fails to meet its obligations and to the extent the Company does not hold sufficient security for its unpaid obligations. Ceded premiums are written during the period in which the risks incept and the associated expense is recognized over the contract period in proportion to the protection provided. Unearned premiums ceded represent the unexpired portion of reinsurance obtained. Reinsurance Assets The Company calculates an allowance for expected credit losses for its reinsurance balances receivable and loss and LAE recoverable by applying a Probability of Default (“PD”) / Loss Given Default (“LGD”) model. The PD / LGD approach considers the Company’s collectibility history on its reinsurance assets and representative external loss history. In calculating the probability of default, the Company also considers the estimated duration of its reinsurance assets. The Company evaluates each counterparty’s creditworthiness based on credit ratings that independent agencies assign to the counterparty. The Company manages its credit risk in its reinsurance assets by transacting only with insurers and reinsurers that it considers financially sound. Credit ratings of the counterparties are forward-looking and consider various economic scenarios. The Company's evaluation of the required allowance for reinsurance balances receivable and loss and LAE recoverable considers the current economic environment as well as potential macroeconomic developments. For its retrocessional counterparties that are unrated, the Company may hold collateral in the form of funds withheld, trust accounts, or irrevocable letters of credit. In evaluating credit risk associated with reinsurance balances receivable, the Company considers its right to offset loss obligations against premiums receivable. The Company regularly evaluates its net credit exposure to assess the ability of cedents and retrocessionaires to honor their respective obligations.
Deposit Assets and Liabilities	Deposit Assets and Liabilities The Company applies deposit accounting to reinsurance contracts that do not transfer sufficient insurance risk to merit reinsurance accounting. Under deposit accounting, the Company recognizes an asset or liability based on its paid or received consideration. The deposit asset or liability balance is subsequently adjusted using the interest method with the corresponding income and expense recorded in the Company’s consolidated statements of operations under “ Other income (expense) ” and “ Deposit interest expense ,” respectively. The Company records deposit assets and liabilities in its consolidated balance sheets in “ Reinsurance balances receivable ” and “ Reinsurance balances payable
Other Income (Expense), net	Other Income (Expense), net In connection with the Company’s participation interest in Lloyd’s syndicates, the Lloyd’s syndicates invest a portion of the premiums withheld in investment funds and fixed-maturity securities. The Company records its share of income (or expense) from these assets as other income (expense) as reported by the syndicates on a quarterly lag basis due to the timing of the availability of these quarterly financial reports.
Share-Based Compensation	Share-Based Compensation The Company recognizes share-based compensation costs based on the fair value at the award’s grant date. The Company measures compensation for restricted shares and restricted stock units (“RSUs”) based on the price of the Company’s common shares at the grant date. For restricted shares and RSUs with service and performance vesting conditions, the expense is recognized based on management’s estimate of the probability of the performance conditions being achieved based on historical results and expectations of future results. If the Company expects to meet the performance conditions, it attributes the expense to the period the requisite service is rendered. For restricted shares and RSUs with only service vesting conditions, the Company recognizes the associated expense on a straight-line basis over the vesting period, net of any estimated or expected forfeitures. The forfeiture rate is estimated based on the Company’s historical actual forfeitures relating to restricted shares and RSUs granted to employees. The forfeiture rate is reviewed annually and adjusted as necessary. The Company applies no forfeiture rate to restricted shares granted to directors, which vest over a maximum twelve-month period. Determining the fair value of share purchase options at the grant date requires significant estimation and judgment. The Company uses the Black-Scholes option-pricing model to assist in the calculation of fair value for share purchase options. The model requires estimating various inputs such as the term, forfeiture and dividend rates, and expected volatility. In determining the grant date fair value, the Company uses the entire ten-year life of the options as the estimated term and assumes no forfeitures and no dividends paid during the life of the options. The Company bases its estimate of expected volatility on the daily historical trading data of the Company’s ordinary shares from the date they commenced trading (May 24, 2007) to the grant date.
Convertible Notes	Convertible Notes Prior to the adoption of Accounting Standards Update (“ASU”) 2020-06 in January 2022, “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”),” the Company determined that the senior convertible notes’ cash conversion option represented an embedded derivative and bifurcated it from the underlying contract for financial reporting purposes. For the debt component, the Company recorded a liability equivalent to the present value of comparable debt without the conversion features at the time of issuance. The remainder of the proceeds, which represented the embedded derivative, was included in “ Additional paid-in capital ” in the consolidated balance sheets. Upon adoption of ASU 2020-06, U.S. GAAP no longer permits entities to bifurcate embedded conversion features from the underlying contract. Therefore, effective January 1, 2022, the Company no longer presents the embedded conversion features separately in equity; instead, the Company’s senior convertible debt is presented as a single liability in the Company’s consolidated balance sheet. The adoption of ASU 2020-06 resulted in a decrease in the Company’s opening shareholders’ equity of $2.5 million, with a corresponding increase in the carrying value of the senior convertible notes. Costs incurred in issuing the convertible notes consisted primarily of underwriting, legal, accounting, and printing fees. These costs are amortized over the term of the debt and are included in “ Interest expense ” in the consolidated statements of operations.
Foreign Exchange	Foreign Exchange The reporting and functional currency of the Company and all its significant subsidiaries is the U.S. dollar. The Company records foreign currency transactions at the exchange rates in effect on the transaction date. Monetary assets and liabilities in foreign currencies are converted at the exchange rate in effect at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currencies are carried at their historical exchange rates.
Derivative Instruments	Derivative instruments The Company recognizes derivative financial instruments in the consolidated balance sheets at their fair values.
Other Assets	Other Assets The Company’s other assets consist primarily of prepaid expenses, right-of-use lease assets, derivative assets, taxes recoverable, and deferred tax assets.
Other Liabilities	Other Liabilities
Comprehensive Income (Loss)	Comprehensive Income (Loss) The Company has no comprehensive income or loss other than the net income or loss disclosed in the consolidated statements of operations.
Earnings (Loss) Per Share	Earnings (Loss) Per Share The Company has issued unvested restricted stock awards, some of which contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid. These awards are considered “participating securities” for the purposes of calculating earnings (loss) per share. Basic earnings per share is calculated on the basis of the weighted average number of ordinary shares and participating securities outstanding during the period. Diluted earnings (or loss) per share includes the dilutive effect, if any, of the following: • Restricted Stock Units (“RSUs”) issued that convert to ordinary shares upon vesting; • Unvested restricted share awards which are not considered “participating securities”; • Additional potential ordinary shares issuable when in-the-money stock options are exercised, determined using the treasury stock method; • For periods prior to January 1, 2022, those ordinary shares with the potential to be issued in connection with convertible notes and other such convertible instruments, determined using the treasury stock method; and • Effective January 1, 2022, the dilutive effect of the convertible notes calculated using the if-converted method. Under the if-converted method, the convertible notes are assumed to be converted at the beginning of the period. The resulting common shares are included in the denominator of the diluted net income per common share calculation. Interest expense related to the convertible notes incurred in the period is added back to the numerator for purposes of the if-converted calculation. Diluted earnings (or loss) per share contemplates a conversion to ordinary shares of all convertible instruments only if they are dilutive. In the event of a net loss, all RSUs, stock options, shares potentially issuable in connection with convertible notes, and participating securities are excluded from the calculation of both basic and diluted loss per share as their inclusion would be anti-dilutive.
Taxation	Taxation The Company records current and deferred income taxes based on enacted tax laws and rates applicable in the relevant jurisdiction in the period in which the tax becomes accruable or realizable. Deferred income taxes are provided for all temporary differences between the bases of assets and liabilities reported in the consolidated balance sheets and those reported in the various jurisdictional tax returns.
Segment Information	Segment Information Operating segments are based on the internal information that the Chief Operating Decision Maker uses for allocating the Company’s resources and assessing its performance. The Company has one operating segment, Property and Casualty Reinsurance.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Standards Not Yet Adopted On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures . The new ASU requires incremental disclosures related to a public entity’s reportable segments but does not change the definition of a segment, the method for determining segments, or the criteria for aggregating operating segments into reportable segments. This new guidance is effective for the Company’s 2024 year-end financial statements, and should be adopted retrospectively unless impracticable. Early adoption is permitted. On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic (740) - Improvements to Income Tax Disclosures . The amendments in this Update provide more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. This ASU is effective for the Company’s 2024 year-end financial statements. As the above ASUs relate solely to financial statement disclosures, the adoption of these ASUs will not impact the Company’s financial condition, results of operations, or cash flows. Recently Issued Accounting Standards Adopted There are none that would be relevant and material to the Company.
