CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This quarterly report and the documents incorporated by reference herein contain statements that constitute "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, with respect to our financial condition, results of operations, business strategies, operating efficiencies, competitive positions, growth opportunities, plans and objectives of our management, as well as the markets for our securities and the insurance and reinsurance sectors in general.

Statements that include words such as "estimate," "project," "plan," "intend," "expect," "anticipate," "believe," "would," "should," "could," "seek," "may" and similar statements of a future or forward-looking nature identify forward-looking statements for purposes of the federal securities laws or otherwise.

All forward-looking statements are necessarily estimates or expectations, and not statements of historical fact, reflecting the best judgment of our management and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements.

These forward looking statements should, therefore, be considered in light of various important factors, including those set forth in this report and in our Annual Report on Form 10-K for the year ended December 31, 2023, which could cause actual results to differ materially from those suggested by the forward-looking statements. These risk factors include:

•the adequacy of our loss reserves and the need to adjust such reserves as claims develop over time, including due to the impact of emerging claim and coverage issues and disputes that could impact reserve adequacy;

•risks relating to our acquisitions, including our ability to evaluate opportunities, successfully price acquisitions, address operational challenges, support our planned growth and assimilate acquired portfolios and companies into our internal control system in order to maintain effective internal controls, provide reliable financial reports and prevent fraud;

•risks relating to climate change and its potential impact on the returns from our run-off business and our investments;

•changes in tax laws or regulations applicable to us or our subsidiaries, including the Bermuda Corporate Income Tax, or the risk that we or one of our non-U.S. subsidiaries become subject to significant, or significantly increased, income taxes in the U.S. or elsewhere;

•the risk that U.S. persons who own our ordinary shares might become subject to adverse U.S. tax consequences as a result of related person insurance income;

•risks relating to our ability to obtain regulatory approvals, including the timing, terms and conditions of any such approvals, and to satisfy other closing conditions in connection with our acquisition agreements, which could affect our ability to complete acquisitions;

•risks relating to the variability of statutory capital requirements and the risk that we may require additional capital in the future, which may not be available or may be available only on unfavorable terms;

•the risk that our reinsurance subsidiaries may not be able to provide the required collateral to ceding companies pursuant to their reinsurance contracts, including through the use of letters of credit;

•risks relating to the availability and collectability of our ceded reinsurance;

•the ability of our subsidiaries to distribute funds to us and the resulting impact on our liquidity;

•losses due to foreign currency exchange rate fluctuations;

•the risk that the value of our investment portfolios and the investment income that we receive from these portfolios may decline materially as a result of market fluctuations and economic conditions, including those related to interest rates, credit spreads and equity prices (including the risk that we may realize losses related to declines in the value of our investments portfolios if we elect to, or are required to, sell investments with unrealized losses);

•risks relating to our ability to structure our investments in a manner that recognizes our liquidity needs;

•risks relating to our strategic investments in alternative asset classes and joint ventures, which are illiquid and may be volatile;

6

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

•risks relating to our ability to accurately value our investments, which requires methodologies, estimates and assumptions that can be highly subjective, and the inaccuracy of which could adversely affect our financial condition;

•risks relating to our liquidity demands and the structure of our investment portfolios, which may adversely affect the performance of our investment portfolio and financial results;

•risks relating to the complex regulatory environment in which we operate, including that ongoing or future industry regulatory developments will disrupt our business, affect the ability of our subsidiaries to operate in the ordinary course or to make distributions to us, or mandate changes in industry practices in ways that increase our costs, decrease our revenues or require us to alter aspects of the way we do business;

•risks relating to laws and regulations regarding sanctions and foreign corrupt practices, the violation of which could adversely affect our financial condition and results of operations;

•loss of key personnel;

•the risk that some of our directors, large shareholders and their affiliates have interests that can create conflicts of interest through related party transactions;

•the risk that outsourced providers could breach their obligations to us which could adversely affect our business and results of operations;

•operational risks, including cybersecurity events, external hazards, human failures or other difficulties with our information technology systems that could disrupt our business or result in the loss of critical and confidential information, increased costs; and

•risks relating to the ownership of our shares resulting from certain provisions of our bye-laws and our status as a Bermuda company.

The factors listed above should not be construed as exhaustive and should be read in conjunction with the Risk Factors that are included in our Annual Report on Form 10-K for the year ended December 31, 2023. We undertake no obligation to publicly update or review any forward-looking statement, whether to reflect any change in our expectations with regard thereto, or as a result of new information, future developments or otherwise, except as required by law.

ENSTAR GROUP LIMITED

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

Enstar Group Limited ("Enstar") is a leading global (re)insurance group that offers innovative capital release solutions through its network of group companies in Bermuda, the United States, the United Kingdom, Continental Europe and Australia. Our core focus is acquiring and managing (re)insurance companies and portfolios of (re)insurance business in run-off.

These unaudited condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the financial information and note disclosures required by U.S. GAAP for complete consolidated financial statements.

In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for a fair statement of the financial results for the interim periods. All intercompany accounts and transactions have been eliminated and certain comparative information has been reclassified to conform to the current presentation.

The results of operations for any interim period are not necessarily indicative of results for the full year. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2023.

Recently Issued Accounting Pronouncements Not Yet Adopted

ASU 2023-07 - Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, which includes the following amendments to Topic 280 Segment Reporting:

•Disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the segment measure of profit or loss;

•Disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition;

•Disclose, on an interim basis, all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280;

•Clarify that an entity is not precluded from reporting one or more additional measure(s) of segment profit or loss if the CODM uses more than one measure in assessing segment performance and deciding how to allocate resources;

•Disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources; and

•Require an entity with a single reportable segment to provide all disclosures required by the amendments in ASU 2023-07 and all existing segment disclosures in Topic 280.

These amendments are effective for annual reporting periods beginning after December 15, 2023 and interim reporting periods beginning after December 15, 2024, and must be applied retrospectively to all prior periods presented. Early adoption is permitted.

Adopting ASU 2023-07 will require us to expand our segment disclosures. We are currently determining the period in which the new guidance will be adopted.

ASU 2023-09 - Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, which includes the following amendments to Topic 740 Income Taxes:

•Disclose, on an annual basis, specific categories in the rate reconciliation;

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      15

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 1. Basis of Presentation

•Disclose, on an annual basis, additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate);

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes;

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received);

•Disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign;

•Disclose income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign;

•Eliminates the requirement to disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or make a statement that an estimate of the range cannot be made; and

•Eliminates the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures.

These amendments are effective for annual reporting periods beginning after December 15, 2024, and should be applied prospectively, however retrospective application is permitted. Early adoption is permitted.

Adopting ASU 2023-09 will require us to expand our income tax disclosures. We are currently determining the period in which the new guidance will be adopted.

2. SEGMENT INFORMATION

Our segment structure is aligned with how our CODM, our Chief Executive Officer, views our business, assesses performance and allocates resources to our business components. Effective January 1, 2024, our business is organized into two reportable segments: (i) Run-off and (ii) Investments. In addition, our Corporate and other activities, which do not qualify as an operating segment, include income and expense items that are not directly attributable to our reportable segments and activities from the former Assumed Life and Legacy Underwriting reportable segments.

Effective January 1, 2024, each of our Assumed Life and Legacy Underwriting reportable segments were determined to no longer meet the definition of reportable segments as they no longer engage in any active business activities following the series of commutation and novation transactions in Enhanzed Re and the settlement of the arrangements between SGL No. 1, Arden, and Atrium. Given the cessation of business activities and that all remaining activities are not expected to be material, all residual income or expense of the former Assumed Life and Legacy Underwriting reportable segments will be prospectively included within our Corporate and other activities.

The Assumed Life segment previously included Enhanzed Re’s life and property aggregate excess of loss (catastrophe) business. In August 2022, Enhanzed Re entered into a Master Agreement with Cavello Bay Reinsurance Limited (“Cavello”), a wholly-owned subsidiary of Enstar, and Allianz, pursuant to which a series of commutation and novation agreements were completed which ceased any continuing reinsurance obligations for this segment. We recognized the impact of transactions that closed in the fourth quarter of 2022 in the first quarter of 2023 due to the quarter lag in reporting.

The Legacy Underwriting segment previously included participation in direct underwriting activities, including a 25% participation within 2020 and prior underwriting years of Atrium's Syndicate 609 at Lloyd's, offset by the contractual transfer of the results of that business to the Atrium entities that were divested in an exchange transaction. All remaining contractual arrangements were settled in the second quarter of 2023. Other than the settlement of these amounts, no other transactions were recorded in the Legacy Underwriting segment in 2023.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 2. Segment Information

Our assets are reviewed on a consolidated basis by management for decision making purposes since they support business operations across both of our reportable segments as well as our Corporate and other activities. We do not allocate assets to our reportable segments with the exception of (re)insurance balances recoverable on paid and unpaid losses and goodwill (all goodwill is attributable to the Run-off segment) that are directly attributable to our reportable segments.

The following table sets forth select unaudited condensed consolidated statements of operations results by segment and our Corporate and other activities:

(1) Effective January 1, 2024, Assumed Life and Legacy Underwriting were determined to no longer meet the definition of reportable segments and their residual income and loss activities were prospectively included in Corporate and other activities. Activities prior to January 1, 2024 are recorded in their respective segments. In addition, Legacy Underwriting had no revenue or income activity for the three months ended March 31, 2024 and 2023 and therefore is excluded from the table above.

(2) Other expense for Corporate and other activities includes the amortization of fair value adjustments associated with the acquisition of DCo and Morse TEC.

(3) Net incurred losses and LAE for Corporate and other activities includes fair value adjustments associated with the acquisition of companies and the changes in the discount rate and risk margin components of the fair value of assets and liabilities related to our assumed retroactive reinsurance contracts for which we have elected the fair value option.

As of March 31, 2024 and December 31, 2023, the number of securities classified as AFS in an unrealized loss position for which an allowance for credit loss is not recorded was 2,363 and 2,156, respectively. Of these securities, the number of securities that had been in an unrealized loss position for twelve months or longer was 1,549 and 1,736, respectively.

The contractual terms of a majority of these investments do not permit the issuers to settle the securities at a price less than the amortized cost basis of the security. While interest rates have increased and credit spreads have widened, and in certain cases credit ratings were downgraded, we currently do not expect the issuers of these fixed maturities to settle them at a price less than their amortized cost basis and therefore it is expected that we will recover the entire amortized cost basis of each security. Furthermore, we do not intend to sell the securities that are currently in an unrealized loss position, and it is also not more likely than not that we will be required to sell the securities before the recovery of their amortized cost bases.

Funds Held - Directly Managed

The following table summarizes the components of the investments collateralizing the funds held - directly managed:

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Funds held - directly managed, at cost	$	2,450	$	2,608
Fair value changes in:
Accumulated change in fair value - embedded derivative accounting	(114)		(106)
Funds held - directly managed, at fair value	$	2,336	$	2,502

The majority of our funds held - directly managed is comprised of short-term and fixed maturities. The $166 million decrease in funds held - directly managed from December 31, 2023 to March 31, 2024 was primarily driven by net paid losses.

Funds Held by Reinsured Companies

The following table summarizes the components of our funds held by reinsured companies:

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Funds held by reinsurance companies, at amortized cost	$	2,522	$	2,709
Fair value of embedded derivative (1)	22		40
Funds held by reinsured companies	$	2,544	$	2,749

(1) Pursuant to the terms of the Aspen Insurance Holdings transaction entered in 2022, in addition to earning a fixed crediting rate (“base crediting rate”) on the funds withheld through September 30, 2025, we receive a variable return (together, the “full crediting rate”). The embedded derivative represents the fair value of the amount by which all future interest payments on the funds withheld balance made at the full crediting rate are expected to exceed all future interest payments made on the funds withheld balance at the base crediting rate.

The $205 million decrease in funds held by reinsured companies from December 31, 2023 to March 31, 2024 was primarily driven by net paid losses specific to the Aspen LPT.

Net Investment Income

Major categories of net investment income are summarized as follows:

	Three Months Ended
	March 31,
	2024		2023
	(in millions of U.S. dollars)
Fixed maturity investments	$	84	$	79

Net Realized Gains (Losses) and Fair Value Changes

Investment purchases and sales are recorded on a trade-date basis. Realized gains and losses on the sale of investments are based upon specific identification of the cost of investments. Components of net realized gains (losses) and fair value changes are recorded within our unaudited condensed consolidated statements of operations were as follows:

	Three Months Ended
	March 31,
	2024		2023
	(in millions of U.S. dollars)
Net realized losses on sales:
Gross realized gains on fixed maturity securities, AFS	$	5	$	5
Gross realized losses on fixed maturity securities, AFS	(10)		(32)
(Increase) decrease in allowance for expected credit losses on fixed maturity securities, AFS	(1)		9
Total net realized losses on sales	$	(6)	$	(18)
Fair value changes in trading securities, funds held and other investments:
Fixed maturity securities, trading	$	(14)	$	40
Funds held - directly managed	(5)		19

Investment derivatives	—		9
Total fair value changes in trading securities, funds held and other investments	$	85	$	206
Net realized gains and fair value changes in trading securities, funds held and other investments	$	79	$	188

The gross realized gains and losses on AFS investments for the three months ended March 31, 2024 and 2023 included in the table above resulted from sales of AFS investments of $436 million and $656 million, respectively.

For the three months ended March 31, 2024 and 2023, fair value changes in trading securities, funds held and other investments recorded within the statement of operations relating to equity securities still held on the balance sheet date were $37 million and $43 million, respectively.

Restricted Assets

The carrying value of our restricted assets, including restricted cash of $310 million and $266 million, as of March 31, 2024 and December 31, 2023, respectively, was as follows: 

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Collateral in trust for third party agreements	$	4,901	$	5,301

Collateral for secured letter of credit facilities	74		78
Funds at Lloyd's (1)	272		389
	$	5,327	$	5,848

(1) We managed and provided capacity for one Lloyd's syndicate as of both March 31, 2024 and December 31, 2023. Lloyd's determines the required capital principally through the use of an internal model that calculates a solvency capital requirement for each syndicate. This capital is referred to as FAL and will be drawn upon in the event that a syndicate has a loss that cannot be funded from other sources.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 4. Derivatives and Hedging Instruments

4. DERIVATIVES AND HEDGING INSTRUMENTS

Accounting for Derivatives

Freestanding Derivatives

Freestanding derivatives are recorded on trade-dates and carried on the consolidated balance sheet either as assets within other assets or as liabilities within other liabilities at estimated fair value. We do not offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting agreement.

If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are reported in fair value changes in trading securities, funds held and other investments included in our consolidated statements of operations.

Hedge Accounting

To qualify for hedge accounting, at the inception of the hedging relationship, we formally document the risk management objective and strategy for undertaking the hedging transaction, as well as the designation of the hedge.

We have qualifying net investment in foreign operation (“NIFO”) hedges. We recognize changes in the estimated fair value of the hedging derivatives within OCI, consistent with the translation adjustment for the hedged net investment in the foreign operation.

Our documentation sets forth how the hedging instrument is expected to hedge the designated risks related to the hedged item and also sets forth the method that will be used to retrospectively and prospectively assess the hedging instrument’s effectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk of the hedged item. Hedge effectiveness is formally assessed at inception and at least quarterly throughout the life of the designated hedging relationship. Assessments of hedge effectiveness are also subject to interpretation and estimation and different interpretations or estimates may have a material effect on the amount reported in net income.

When hedge accounting is discontinued pursuant to a NIFO hedge (due to a revaluation, payment of a dividend or the disposal of our investment in a foreign operation), the derivative continues to be carried on the balance sheet at its estimated fair value. Deferred gains and losses recorded in OCI pursuant to a discontinued NIFO hedge are recognized immediately in net foreign exchange losses (gains) in our consolidated statements of operations.

Embedded Derivatives

We are party to certain reinsurance agreements that have embedded derivatives. We also have embedded derivatives on our convertible bond portfolio, recorded within fixed maturities, trading on the consolidated balance sheets. We assess each identified embedded derivative to determine whether it is required to be bifurcated. The embedded derivative is bifurcated from the host contract and accounted for as a freestanding derivative if:

•the combined instrument is not accounted for in its entirety at estimated fair value with changes in estimated fair value recorded in net income;

•the terms of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract; and

•a separate instrument with the same terms as the embedded derivative would qualify as a derivative instrument.

Such embedded derivatives are carried on the consolidated balance sheet at estimated fair value with the host contract and changes in their estimated fair value are generally reported within fair value changes in trading securities, funds held and other investments.

Derivative Strategies

We are exposed to various risks relating to our ongoing business operations, including interest rate, foreign currency exchange rate, credit and equity price risks. We use a variety of strategies to manage these risks, including the use of derivatives.

Derivatives are financial instruments with values derived from interest rates, foreign currency exchange rates, credit spreads and/or other financial indices. The types of derivatives we use include swaps and forwards.

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      25

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 4. Derivatives and Hedging Instruments

Foreign Currency Derivatives

We use foreign currency exchange rate derivatives, including foreign currency forwards, to reduce the risk from fluctuations in foreign currency exchange rates associated with our assets and liabilities denominated in foreign currencies. We also use foreign currency derivatives to hedge the foreign currency exchange rate risk associated with certain of our net investments in foreign operations.

In a foreign currency forward transaction, we agree with another party to deliver a specified amount of an identified currency at a specified future date. The price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. We utilize foreign currency forwards in fair value, NIFO hedges and nonqualifying hedging relationships.

Interest Rate Derivatives

We use interest rate derivatives, specifically interest rate swaps, to reduce our exposure to changes in interest rates.

Interest rate swaps are used by us primarily to reduce market risks from changes in interest rates and to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches). In an interest rate swap, we agree with another party to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts as calculated by reference to an agreed notional amount. We utilize interest rate swaps in nonqualifying hedging relationships.

In February 2023, we entered into a two-month forward interest rate swap, receiving a fixed rate and paying a floating rate with a notional value of $800 million to partially mitigate the risk that interest rates could decrease prior to our receipt of the cash consideration for the QBE LPT transaction. Following the expiration of the forward period in April 2023, we took delivery of a three-year receive fixed, pay floating interest rate swap. The notional value of the swap was subsequently partially unwound as the consideration received was invested. The swap was fully unwound in July 2023. As of March 31, 2024 and December 31, 2023, we had no interest rate swaps.

The following table presents the gross notional amounts and estimated fair values of our derivatives recorded within other assets and other liabilities on the consolidated balance sheets as of March 31, 2024 and December 31, 2023:

	March 31, 2024						December 31, 2023

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 5. Deferred Charge Assets and Deferred Gain Liabilities

5. DEFERRED CHARGE ASSETS AND DEFERRED GAIN LIABILITIES

If, at the inception of a retroactive reinsurance contract, the estimated liabilities for losses and LAE exceed the consideration received, a deferred charge asset (“DCA”) is recorded for this difference. In contrast, if the consideration received is in excess of the estimated undiscounted ultimate losses payable, a deferred gain liability (“DGL”) is recorded.

We amortize the net DCA balances over the estimated claim payment period of the related contracts with the amortization prospectively adjusted at each reporting period to reflect new estimates of the pattern and timing of remaining losses and LAE payments.

The following table presents a summary of the DCA balances and related activity for the three months ended March 31, 2024 and 2023 (there were no DGL balances in either period):

	Three Months Ended March 31,
	2024		2023
	(in millions of U.S. dollars)
Beginning carrying value	$	731	$	658
Amortization	(30)		(17)
Ending carrying value	$	701	$	641

For each of the three months ended March 31, 2024 and 2023, we completed our assessment for impairment of deferred charge assets and concluded that there had been no impairment of our carried deferred charge asset balances.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 6. Losses and Loss Adjustment Expenses

6. LOSSES AND LOSS ADJUSTMENT EXPENSES

The liability for losses and LAE, also referred to as loss reserves, represents our gross estimates before reinsurance for unpaid reported losses (Outstanding Loss Reserves, or "OLR") and includes losses that have been incurred but not yet reported ("IBNR") using a variety of actuarial methods. We recognize an asset for the portion of the liability that we expect to recover from reinsurers. LAE reserves include allocated LAE ("ALAE") and unallocated LAE ("ULAE"). ALAE are linked to the settlement of an individual claim or loss, whereas ULAE are based on our estimates of future costs to administer the claims. IBNR includes amounts for unreported claims, development on known claims and reopened claims.

Our loss reserves cover multiple lines of business, including asbestos, environmental, general casualty, workers' compensation, marine, aviation and transit, construction defect, professional indemnity/directors and officers, motor, property and other non-life lines of business. We complete most of our annual loss reserve studies in the fourth quarter of each year and, as a result, tend to record the largest movements, both favorable and adverse, to net incurred losses and LAE in this period.

We have elected to apply the fair value option for certain reinsurance contracts including, loss portfolio transfers ("LPTs") and reinsurance to close ("RITC") transactions. This is an irrevocable election that applies to all balances under the reinsurance contract, including reinsurance balances recoverable on paid and unpaid losses and the liability for losses and LAE. The primary reason for electing the fair value option was to reduce the earnings volatility created by carrying the liabilities for losses and LAE at cost and the assets supporting those liabilities at fair value. During 2017 and 2018, we elected the fair value option on select new business and classified the supporting portfolio investments as trading securities, whereby all changes in fair value were recorded in the statements of operations. Commencing in 2019, we discontinued electing the fair value option on new business in order to better align with our evolving investment objectives.

Prior Period Development

Reduction in Estimates of Net Ultimate Losses

The following table summarizes the change in estimates of net ultimate losses related to prior years in our Run-off segment by line of business:

	Three Months Ended
	March 31, 2024		March 31, 2023
	(in millions of U.S. dollars)

Motor	4		—
Property	(1)		(3)
All Other	1		(2)
Total	$	(6)	$	(15)

Three Months Ended March 31, 2024:

The prior period reduction in estimates of net ultimate losses of $6 million was driven by favorable development across multiple lines of business. The primary drivers included favorable development on our Professional Indemnity/Directors and Officers line of business of $29 million, driven by favorable claims experience and favorable development on our Asbestos line of business of $24 million resulting from actuarial analysis. These were partially offset by adverse development on our General Casualty line of business of $18 million driven by adverse claims experience and adverse development on our Environmental line of business of $25 million due to results from actuarial reviews in the period.

Three Months Ended March 31, 2023:

The reduction in estimates of net ultimate losses of $15 million related to prior periods was primarily due to the workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Reduction in Provisions for ULAE

Three Months Ended March 31, 2024 and 2023:

The favorable reduction in provisions for ULAE for the three months ended March 31, 2024 and 2023 was driven by ULAE provision adjustments, due to the corresponding reductions in loss reserves and the associated estimated cost of managing such liabilities.

Changes in Fair Value - Fair Value Option

Three Months Ended March 31, 2024 and 2023:

PPD for the three months ended March 31, 2024 was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $4 million, which was primarily driven by an increase in U.K. corporate bond yields during the first quarter of 2024. The corporate bond yields, which form a component of the discount rate used to calculate the fair value of the liabilities, are matched to the original currencies of the underlying loss portfolios, of which GBP is the predominant currency for those portfolios that we have elected to measure at fair value using the fair value option.

PPD for the three months ended March 31, 2023 was adversely impacted by changes in the fair value of liabilities for which we have elected the fair value option of $20 million due to a decline in corporate bond yields.

Item 1 | Notes to Consolidated Financial Statements | Note 7. Future Policyholder Benefits

7. FUTURE POLICYHOLDER BENEFITS

The provision for future policyholder benefits includes provisions for life contingent liabilities assumed as well as other policy benefits for insureds. The future policyholder benefits are equal to the present value of the future benefits payments and related expenses less the present value of future net premiums.

The assumed liabilities for future policyholder benefits are comprised primarily of in-payment annuity contract liabilities, which are classified as limited-payment contracts. The balances of and changes in liability for future policyholder benefits is as follows:

	Three Months Ended March 31,

Beginning Balance	$	821
Benefits paid	(6)
Effect of exchange rate movement	13
Derecognition (1)	(828)
Balance as of March 31	—

(1) In November 2022, we completed a novation of the reinsurance of a closed block of life annuity policies, which was recorded in our first quarter 2023 results due to a one quarter reporting lag. See below for additional information.

There were no gross premiums recognized for the three months ended March 31, 2023.

The effects of actual variances from expected policyholder behavior experience were not material for the three month period ended March 31, 2023.

Novation of Future Policyholder Benefits

In November 2022, Enhanzed Re completed a novation of the reinsurance of a closed block of life annuity policies to Monument Re Limited, a subsidiary of Monument Insurance Group Limited (“Monument Re”). We settled the life liabilities and the related assets at carrying value in return for cash consideration of $94 million as of the closing date and recorded other income of $275 million. This amount consists of a reclassification adjustment of the component of AOCI related to the unlocking of the discount rate assumption from the adoption of ASU 2018-12 into earnings. Our net income attributable to Enstar was reduced by the amount attributable to Allianz’s 24.9% noncontrolling interest in Enhanzed Re at the time of the transaction and our other income recorded was subject to deferral as profits emerge from the underlying novated business, which is generally over the expected settlement period of the life annuity policies, to account for our 20% ownership interest in Monument Re at the time of the transaction.

(2) Calculated as 20% of the net Enstar transaction gain of $243 million (representing $324 million, consisting of the $39 million loss when comparing cash consideration to carrying value plus the $363 million reclassification benefit, less Allianz’s 24.9% share equal to $81 million).

(3) Recognized in other income in our unaudited condensed consolidated statements of operations.

(4) Recognized in net income in our unaudited condensed consolidated statements of operations.

During the three months ended March 31, 2024, we amortized $1 million into other income relating to the portion of the gain that was deferred to account for our preexisting ownership interest in Monument Re. For the three months ended March 31, 2023 the total gain on novation attributable to Enstar was $194 million. The remaining deferred gain of $47 million as of March 31, 2024 will be amortized over the expected settlement period of the transferred life annuity policies, which is projected to be approximately 50 years, with the majority of benefit payments occurring in the earlier years.

9. FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants. We use a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. The hierarchy is broken down into three levels as follows:

•Level 1 - Valuations based on unadjusted quoted prices in active markets that we have the ability to access for identical assets or liabilities. Valuation adjustments and block discounts are not applied to Level 1 instruments.

•Level 2 - Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or significant inputs that are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

•Level 3 - Valuations based on unobservable inputs where there is little or no market activity. Unadjusted third party pricing sources or management's assumptions and internal valuation models may be used to determine the fair values.

In addition, certain of our other investments are measured at fair value using net asset value ("NAV") per share (or its equivalent) as a practical expedient and have not been classified within the fair value hierarchy as defined above.

There have been no material changes in our valuation techniques during the period represented by these unaudited condensed consolidated financial statements.

Level 3 Measurements and Changes in Leveling

Transfers into or out of levels are recorded at their fair values as of the end of the reporting period, consistent with the date of determination of fair value.

Investments

The following table presents a reconciliation of the beginning and ending balances for all investments measured at fair value on a recurring basis using Level 3 inputs:

(1) Fair value changes in trading securities, funds held and other investments included in our unaudited condensed consolidated statements of operations is equal to the change in fair value changes in trading securities, funds held and other investments relating to assets held at the end of the reporting period.

Fair value changes in trading securities, funds held and other investments related to Level 3 assets in the tables above are included in fair value changes in trading securities, funds held and other investments in our unaudited condensed consolidated statements of operations.

Transfers into Level 3 are primarily attributable to the lack of observable market transactions and price information and the use of unobservable inputs within valuation methodologies.

Below is a summary of the quantitative information regarding the significant observable and unobservable inputs used in the internal model to determine fair value on a recurring basis:

Valuation Technique		March 31, 2024	December 31, 2023
	Unobservable (U) and Observable (O) Inputs	Weighted Average
Internal model	Corporate bond yield (O)	A Rated	A Rated
Internal model	Credit spread for Instrument-specific credit risk (U)	0.65%	0.65%
Internal model	Risk cost of capital (U)	5.65%	5.60%
Internal model	Weighted average cost of capital (U)	8.75%	8.75%
Internal model	Average payout - liability (U)	8.13 years	8.12 years
Internal model	Average payout - reinsurance balances recoverable on paid and unpaid losses (U)	8.53 years	8.35 years

The fair value of the liability for losses and LAE and reinsurance balances recoverable on paid and unpaid losses may increase or decrease due to changes in the corporate bond rate, the credit spread for non-performance risk, the risk cost of capital, the weighted average cost of capital and the estimated payment pattern.

In addition, the estimate of the capital required to support the liabilities is based upon current industry standards for capital adequacy.

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      39

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 9. Fair Value Measurements

Changes in the fair value due to changes in average payout and corporate bond yields are included in net incurred losses and loss adjustment expenses in our unaudited condensed consolidated statements of earnings. Changes in the fair value due to changes in credit spread for Instrument-specific credit risk are classified to other comprehensive income.

Disclosure of Fair Values for Financial Instruments Carried at Cost

Senior and Junior Subordinated Notes

The following table presents the fair values of our Senior and Junior Subordinated Notes carried at amortized cost:

	March 31, 2024
	Amortized Cost		Fair Value
	(in millions of U.S. dollars)
4.95% Senior Notes due 2029	$	496	$	489

5.50% Junior Subordinated Notes due 2042	494		467
Total Junior Subordinated Notes	$	840	$	808

The fair value of our Senior Notes and our Junior Subordinated Notes was based on observable market pricing from a third party pricing service.

Both the Senior Notes and Junior Subordinated Notes are classified as Level 2.

Insurance Contracts

Disclosure of fair value of amounts relating to insurance contracts is not required, except those for which we elected the fair value option, as described above.

Remaining Financial Assets and Liabilities

Our remaining financial assets and liabilities were generally carried at cost or amortized cost, which due to their short-term nature approximates fair value as of March 31, 2024 and December 31, 2023.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 10. Variable Interest Entities

10. VARIABLE INTEREST ENTITIES

We have investments in certain limited partnership funds which are deemed to be variable interest entities ("VIEs"). The activities of these VIEs are generally limited to holding investments and our involvement in these entities is passive in nature. We consolidate all VIEs in which we are considered to be the primary beneficiary.

GCM Fund

In July 2022, we entered into an agreement to become a limited partner of GCM Blue Sails Infrastructure Offshore Opportunities Fund, L.P. (“GCM Fund”), with an initial commitment of $150 million. At that time, we performed an assessment and concluded that as a result of being a limited partner and having no substantive kick-out or participating rights, the GCM Fund is a VIE. We also concluded that we are the primary beneficiary, as our 99.5% economic interest in the GCM Fund is disproportionately greater than our lack of stated power to direct the activities of the GCM Fund that will most significantly impact the GCM Fund’s economic performance. As a result, we have consolidated the results of the GCM Fund. There was no gain or loss recognized on consolidation.

We recognize the results of the GCM Fund on a one quarter lag. As of March 31, 2024, $100 million of the initial commitment has been called. The carrying amounts of the assets and liabilities of the GCM Fund are presented within existing captions on our consolidated balance sheet as of March 31, 2024. Net investment income, changes in the fair value of assets and liabilities of the GCM Fund and management fees are presented within existing captions in the consolidated statements of operations.

We recognized fair value changes in trading securities, funds held and other investments of $1 million for the three months ended March 31, 2024. Such amounts were less than $1 million for the three months ended March 31, 2023.

Our exposure to risk of loss is limited to the amount of our investment, in accordance with the limited partnership agreement. We have not committed to provide any financial support to the general partner of the GCM Fund. In addition, we have not committed to provide any additional financial support to the GCM Fund in excess of previously funded capital commitments and all undistributed profits and income.

The assets of Enstar are not available to the creditors of the GCM Fund.

Nonconsolidated VIEs

The tables below present the fair value of our investments in nonconsolidated VIEs as well as our maximum exposure to loss associated with these VIEs:

11. NONCONTROLLING INTERESTS

Redeemable Noncontrolling Interests

In December 2023, we entered into a Purchase Agreement with Trident V Funds and Dowling Capital Partners (together, the “RNCI Holders”) to purchase their remaining equity interest in StarStone Specialty Holdings Limited (“SSHL”). Following the completion of the transaction in December 2023, SSHL became a wholly-owned subsidiary and all redeemable non-controlling interests (“RNCI”) within our unaudited condensed consolidated balance sheets were redeemed.

The following is a reconciliation of the beginning and ending carrying amount of the equity attributable to the RNCI in the prior year period (as of December 2023 we no longer held any RNCI): 

	Three Months Ended
	March 31,
	2023
	(in millions of U.S. dollars)
Balance at beginning of period	$	168
Net income attributable to RNCI	1
Change in unrealized gains on AFS investments attributable to RNCI	1
Balance as of March 31	$	170

Noncontrolling Interests

As of March 31, 2024 and December 31, 2023, we had $114 million and $113 million, respectively, of non-controlling interests (“NCI”) primarily related to external interests in our subsidiaries.

In December 2022, Enhanzed Re repurchased the entire 24.9% ownership interest Allianz held in Enhanzed Re for $175 million. We recorded the impact of reclassifying the carrying value of the NCI acquired to Enstar shareholders’ equity in our first quarter 2023 results, as we report the results of Enhanzed Re on a one quarter reporting lag.

A reconciliation of the beginning and ending carrying amount of the equity attributable to NCI is included in the unaudited condensed consolidated statements of changes in shareholder's equity.

Strategic Share Repurchases

In March 2023, we repurchased 1,597,712 of our non-voting convertible ordinary shares held by Canada Pension Plan Investment Board (“CPP Investments”) for an aggregate $341 million, representing a price per share of $213.13 and a 5% discount to the trailing 10-day volume weighted average price of our voting ordinary shares as at the agreed March 2023 measurement date. The shares comprised all of our outstanding Series C and Series E non-voting ordinary shares.

There were no non-voting ordinary shares repurchased during the three months ended March 31, 2024.

Dividends on Preferred Shares

During the three months ended March 31, 2024 and 2023, we declared and paid dividends on Series D Preferred Shares of $7 million and on Series E Preferred Shares of $2 million for both periods.

13. EARNINGS PER SHARE

The following table sets forth the computation of basic and diluted net earnings per ordinary share:

	Three Months Ended
	March 31,
	2024		2023
	(in millions of U.S. dollars, except share and per share data)
Numerator:
Net income attributable to Enstar ordinary shareholders:	$	119	$	424
Denominator:
Weighted-average ordinary shares outstanding — basic (1)	14,641,158		16,980,240
Effect of dilutive securities:
Share-based compensation plans (2)	192,682		120,714
Weighted-average ordinary shares outstanding — diluted	14,833,840		17,100,954
Earnings per share attributable to Enstar ordinary shareholders:
Basic	$	8.13	$	24.97
Diluted	$	8.02	$	24.79

(1) Weighted-average ordinary shares for basic earnings per share includes ordinary shares (voting and non-voting), but excludes ordinary shares held in the Enstar Group Limited Employee Benefit Trust (the "EB Trust") in respect of Joint Share Ownership Plan ("JSOP") awards, which, as a result of us consolidating the EB trust, are classified as treasury shares.

(2) Share-based dilutive securities include restricted shares, restricted share units, directors’ restricted share units and performance share units. Certain share-based compensation awards were excluded from the calculation for the three months ended March 31, 2024 and 2023 because they were anti-dilutive.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 15. Commitments and Contingencies

15. COMMITMENTS AND CONTINGENCIES

Concentration of Credit Risk

We are subject to credit risk principally in relation to our:

i.investments, including equity method investments;

ii.cash and cash equivalents and restricted cash and cash equivalents;

iii.assets pledged to ceding companies under reinsurance contracts;

iv.(re)insurance balances recoverable on paid and unpaid losses; and

v.funds held by reinsured companies and funds held - directly managed (together funds held).

As of March 31, 2024, we had funds held concentrations to reinsurance counterparties exceeding 10% of shareholders’ equity of $4.5 billion (December 31, 2023: $4.8 billion) in aggregate. However, we generally have the contractual ability to offset any shortfall in the payment of the funds held balances with amounts owed by us.

We limit the amount of credit exposure to any one counterparty, and none of our counterparty credit exposures, excluding U.S. government and agency instruments and the reinsurance counterparties noted above, exceeded 10% of shareholders’ equity as of March 31, 2024. As of March 31, 2024, our credit exposure to the U.S. government and agency instruments was $848 million (December 31, 2023: $932 million).

Legal Proceedings

We are, from time to time, involved in various legal proceedings in the ordinary course of business, including litigation and arbitration regarding claims. Estimated losses relating to claims arising in the ordinary course of business, including the anticipated outcome of any pending arbitration or litigation, are included in the liability for losses and LAE in our unaudited condensed consolidated balance sheets. In addition to claims litigation, we may be subject to other lawsuits and regulatory actions in the normal course of business, which may involve, among other things, allegations of underwriting errors or omissions, employment claims or regulatory activity. We do not believe that the resolution of any currently pending legal proceedings, either individually or taken as a whole, will have a material effect on our business, results of operations or financial condition. We anticipate that, similar to the rest of the (re)insurance industry, we will continue to be subject to litigation and arbitration proceedings in the ordinary course of business, including litigation generally related to the scope of coverage with respect to A&E and other claims.

Unfunded Investment Commitments

As of March 31, 2024, we had unfunded commitments of $1.6 billion to other investments, and $12 million to privately held equity.

Guarantees

As of March 31, 2024, and December 31, 2023 parental guarantees supporting reinsurance obligations, defendant A&E liabilities, subsidiary capital support arrangements and credit facilities were $2.3 billion, for both periods. We also guarantee the 2040 and 2042 Junior Subordinated Notes, which have an aggregate principal amount of $850 million as of March 31, 2024 and December 31, 2023.

Consolidated Results of Operations - For the Three Months Ended March 31, 2024 and 2023

Primary GAAP Financial Measures

We use the following GAAP measures to manage the company and monitor our performance:

•Net income and net income attributable to Enstar ordinary shareholders, collectively provide a measure of our performance focusing on underwriting, investment and expense results;

•Comprehensive income attributable to Enstar, which provides a measure of the total return, including unrealized gains and losses on fixed maturities, AFS investments, as well as other elements of other comprehensive income;

•Book value per share (“BVPS”), which we use to measure the value of our company over time;

•Return on equity (“ROE”), which measures our profitability by dividing our net income attributable to Enstar ordinary shareholders by opening Enstar ordinary shareholders’ equity;

•Total investment return (“TIR”), which measures the rate of return we obtain, realized, unrealized and fair value changes, on our investments; and

•Run-off liability earnings (“RLE”) and RLE %, which measure both the dollar amount of prior period development on our acquired portfolios (RLE) and the percentage of prior period development relative to average net loss reserves, calculated by dividing our prior period development by our average net loss reserves (RLE %).

Item 2 | Management's Discussion and Analysis | Consolidated Results of Operations

Overall Results

Three Months Ended March 31, 2024 versus 2023:

Net income attributable to Enstar ordinary shareholders for the three months ended March 31, 2024 was $119 million, in comparison to net income of $424 million in the comparative quarter, as a result of:

•A decrease in other income of $280 million largely driven by the first quarter 2023 net gain recognized from the novation of the Enhanzed Re reinsurance closed block of life annuity policies included in the comparative quarter.

•An increase in the amortization of net deferred charge assets of $13 million, driven by an increase in net DCA balances as a result of transactions completed subsequent to March 31, 2023.

•Total investment returns recognized in income of $234 million for the three months ended March 31, 2024, in comparison to $355 million for the comparative quarter, consisting of the aggregate of net investment income, net realized losses, fair value changes in trading securities, funds held and other investments and (loss) income from equity method investments. The total investment returns in each period were driven by:

◦Fair value changes in our fixed maturities resulting in a $19 million loss for the three months ended March 31, 2024 compared with a gain of $59 million in the comparative quarter;

◦Fair value changes in our other investments, including equities resulting in a of $104 million gain for the three months ended March 31, 2024 compared with $147 million in the comparative quarter;

◦Net investment income of $160 million for the three months ended March 31, 2024 compared to $156 million in the comparative quarter, consistent with the increasing investment income we have earned, primarily due to reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed over the past 12 months and the impact of rising interest rates on our floating rate fixed maturities; and

◦Net realized losses on our fixed maturities of $6 million, for the three months ended March 31, 2024 compared to $18 million in the comparative quarter.

This was partially offset by:

•An increase of $14 million in favorable development in net incurred losses and LAE for prior periods. Net favorable development of $24 million in the current period was primarily due to a reduction in our estimates of net ultimate losses and provisions for ULAE of $23 million and a $4 million decrease in the fair value of our 2017 and 2018 LPT liabilities where we elected the fair value option, partially offset by amortization of fair value adjustments of $3 million. First quarter 2023 net favorable development of $10 million was primarily due to a reduction in our estimates of net ultimate losses and provisions for ULAE of $33 million, partially offset by amortization of fair value adjustments of $3 million and a $20 million increase in the fair value of liabilities where we elected the fair value option due to a decrease in interest rates. This resulted in RLE of 0.2% for the three months ended March 31, 2024 in comparison to RLE of 0.1% in the comparative quarter; and

•A decrease in net income attributable to non-controlling interests of $86 million, as a result of recording the portion of the gain on novation of the Enhanzed Re reinsurance closed block of life annuity policies attributable to Allianz’s equity interest in Enhanzed Re in the comparative quarter.

The above factors contributed to net income of $128 million for the three months ended March 31, 2024 as compared to $519 million in the comparative quarter, as well as net income attributable to Enstar ordinary shareholders of $119 million as compared to $424 million in the comparative quarter. Consequently, our ROE was 2.4% in the current quarter compared to 9.5% in the comparative quarter.

Comprehensive income attributable to Enstar for the three months ended March 31, 2024 was $100 million as compared to $239 million in the comparative quarter. The first quarter 2024 comprehensive income was primarily due to net income of $128 million partially offset by unrealized losses on fixed maturities, AFS, net of reclassification adjustments, of $27 million. The unrealized losses on our fixed maturities, AFS, combined with our favorable investment results, described above, contributed to a net favorable Annualized TIR of 4.9% for the three months ended March 31, 2024, in comparison to a Annualized TIR of 9.5% in the comparative quarter.

BVPS and FDBVPS* increased by 1.7% and 1.4%, respectively, from December 31, 2023 to March 31, 2024, primarily due to comprehensive income attributable to Enstar for the quarter ended which contributed to both BVPS and FDBVPS*.

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      55

Item 2 | Management's Discussion and Analysis | Consolidated Results of Operations

The cumulative unrealized loss and fair value changes in our fixed maturities portfolio and funds held was $789 million as of March 31, 2024, which has adversely impacted BVPS by $53.82 per share and FDBVPS* by $52.61 per share. This compares to $994 million of cumulative unrealized loss and fair value changes in our fixed maturities portfolio and funds held as of March 31, 2023.

Overall Measures of Performance

BVPS and Fully Diluted BVPS*

BVPS and Fully Diluted BVPS* increased by 1.7% and 1.4%, respectively, from December 31, 2023 to March 31, 2024, primarily as a result of comprehensive income attributable to Enstar of $100 million. The cumulative unrealized loss and fair value changes in our fixed maturities portfolio and funds held was $789 million as of March 31, 2024, which adversely impacted BVPS by $53.82 per share and FDBVPS* by $52.61 per share.

ROE and Adjusted ROE

Three Months Ended March 31, 2024 versus 2023: ROE decreased by 7.1 pp for the three months ended March 31, 2024 primarily due to:

i.decreased other income, comprised primarily of the gain recognized on the novation of the Enhanzed Re reinsurance closed block of life annuity policies in the comparative quarter, which contributed 6.3 pp to the decrease in ROE;

ii.fair value changes in trading securities, funds held and other investments which contributed 2.9 pp to the decrease in ROE;

These factors were partially offset by:

iii. increased favorable prior period development, or RLE, which offset the decrease in ROE by 0.3 pp; and

iv. decreased net income attributable to noncontrolling interests, which offset the decrease in ROE by 1.9 pp.

Adjusted ROE* decreased by 4.2 pp for the three months ended March 31, 2024, as it excludes the impact of net realized losses and changes in the fair value of fixed maturities.

Item 2 | Management's Discussion and Analysis | Consolidated Results of Operations

We discuss the results of our operations by aggregating certain captions from our unaudited condensed consolidated statements of operations, as we believe it provides a more meaningful view of our results and eliminates repetition that would arise if captions were discussed on an individual basis.

In order to facilitate analysis, we have grouped the discussion into the following captions:

•Technical results: includes net premiums earned, net incurred losses and LAE and acquisition costs.

•Investment results: includes net investment income, net realized (losses) gains, fair value changes in trading securities, funds held and other investments, unrealized (losses) gains on fixed maturities, AFS (recorded through the unaudited condensed consolidated statements of other comprehensive income) and income (losses) from equity method investments.

•General and administrative results: includes general and administrative expenses.

Technical Results

Our strategy is focused on effectively managing (re)insurance portfolios underwritten in previous years that we assume through our provision of capital release solutions and acquisition of portfolios and businesses in run-off.

Net premiums earned and the associated current period net incurred losses and LAE and acquisition costs are the result of the recognition of unearned premiums from transactions completed in recent years.

Premiums earned in the Run-off segment are generally offset by the related current period net incurred losses and LAE and acquisition costs.

The components of technical results are as follows:

	Three Months Ended March 31,
	2024						2023
	Run-off		Corporate and other		Total		Run-off		Corporate and other		Total

The following tables summarize RLE, RLE %, Adjusted RLE* and Adjusted RLE %* by acquisition year for the three months ended March 31, 2024 and 2023, which management believes is useful in measuring and monitoring performance of our claims management activity on the portfolios that we have acquired. This permits comparability between acquisition years of different loss reserve volumes.

*Non-GAAP measure; refer to “Non-GAAP Financial Measures” section for reconciliation to the applicable GAAP financial measure.

Three Months Ended March 31, 2024:

Our RLE % was 0.2% for the three months ended March 31, 2024, as favorable reductions in estimates of net ultimate losses, reductions in provisions for ULAE and net favorable changes in the fair value of liabilities for which we have elected the fair value option were partially offset by amortization of fair value adjustments.

Acquisition years 2021 and 2022 provided favorable results, driven by our professional indemnity/directors and officers, workers’ compensation and general casualty lines of business, as a result of favorable claims experience. Partially offsetting this, acquisition years 2020 and prior were unfavorably impacted by increased settlement activity in general casualty.

Our Adjusted RLE %* was marginally impacted by the net reduction in estimates of net ultimate losses and reductions in provisions for ULAE. It also excludes the impact of the changes in the discount rate upon the fair value of liabilities where we have elected the fair value option and the amortization of fair value adjustments relating to purchased subsidiaries.

Three Months Ended March 31, 2023:

Our RLE % was almost flat for the three months ended March 31, 2023, as favorable reductions in estimates of net ultimate losses and reductions in provisions for ULAE were largely offset by unfavorable changes in the fair value of liabilities for which we have elected the fair value option.

Unfavorable RLE in the 2017 and 2018 acquisition years was driven predominantly by an increase in the fair value of liabilities for which we have elected the fair value option. Acquisition year 2018 was also adversely impacted by adverse to expected claims experience on certain of our general casualty portfolios.

Favorable RLE in the 2020 acquisition year was driven by a release of $10 million relating to COVID-19 exposures on our general casualty line of business.

Favorable RLE in the 2021 acquisition year was driven by continued favorable claims experience to expected on our workers’ compensation line of business.

Our Adjusted RLE %* was positively impacted by the net reduction in estimates of net ultimate losses and the reduction in provisions for ULAE relating to the Run-off segment. It excludes the impact of the changes in the discount rate upon the fair value of liabilities where we have elected the fair value option and the amortization of fair value adjustments relating to purchased subsidiaries.

Investment Results

We strive to structure our investment holdings and the duration of our investments in a manner that recognizes our liquidity needs, including our obligation to pay losses and LAE liabilities.

The components of our investment results split between our fixed income assets (which includes our short-term and fixed maturities classified as trading and AFS, funds held, cash and cash equivalents and restricted cash and cash equivalents, collectively our “Fixed Income” assets) and other investments (which includes equities and equity method investments, collectively our “Other Investments”) for the three months ended March 31, 2024 and 2023 are as follows:

Net Investment Income

The below chart is in millions of U.S. dollars.

Three Months Ended March 31, 2024 versus 2023: Net investment income increased primarily due to:

•an increase in our annualized investment book yield of 78 basis points due to a combination of investment of new premium and reinvestment of fixed maturities at higher yields and the impact of rising interest rates on the $3.1 billion of our fixed maturities that are subject to floating interest rates. Our floating rate investments generated net investment income of $58 million, an increase of $2 million in comparison to the prior period.

Fair Value Changes, Net Realized Losses and Unrealized (Losses) Gains included in Comprehensive Income

The below chart is in millions of U.S. dollars.

Three Months Ended March 31, 2024 versus 2023: The net reduction of $208 million when comparing fair value changes, realized losses and unrealized (losses) gains on fixed maturities, AFS for the three months ended March 31, 2024 to the comparative period was the result of:

•the current period overall loss from the total of fair value changes, realized losses and unrealized losses, AFS on fixed maturities of $37 million, compared to the overall gain from the comparative quarter of $128 million. The variance of $165 million was primarily driven by increases in interest rates across U.S., U.K. and European markets in the current period, in comparison to decreases in interest rates in the prior period; and

•the current period gain from fair value changes on other investments, including equities, of $104 million, compared to $147 million in the comparative period. The decrease of $43 million was primarily driven by:

◦a decrease in the gain on fair value change in other investments of $18 million for the three months ended March 31, 2024, primarily driven by variance in the fair value change of an embedded derivative in relation to the Aspen LPT, partially offset by increases in the fair value change related to CLO equity funds, private equity funds and high yield bond and loan funds relative to the comparative quarter; and

◦a decrease in the gain in fair value changes in equities of $16 million for the three months ended March 31, 2024, largely as a result of the reduced amount of equities within the investment portfolio relative to the comparative quarter.

(Loss) income from equity method investments

The below chart is in millions of U.S. dollars.

Three Months Ended March 31, 2024 versus 2023: The unfavorable movement in income from equity method investments of $16 million was primarily due to a $29 million increase in the loss from our investment in Monument Re, partially offset by an increase in our income from our investment in Core Specialty of $15 million.

Investable Assets

Investable assets and adjusted investable assets* decreased by 3.1% and 2.6%, respectively, from December 31, 2023 to March 31, 2024, primarily due to the impact of net paid losses, partially offset by investment income and the fair value change in our fixed maturities.

*Non-GAAP measure; refer to "Non-GAAP Financial Measures" section for reconciliation to the applicable GAAP financial measures.

Duration and average credit rating on fixed maturities, cash and cash equivalents and fixed maturities included in funds held - directly managed

The fair value, duration and average credit rating of investments (all attributable to our Run-off segment) is as follows:

	March 31, 2024				December 31, 2023
	Fair Value ($) (1)		Average Duration (in years) (2)	Average Credit Rating (3)	Fair Value ($) (1)		Average Duration (in years) (2)	Average Credit Rating (3)
Total	$	9,733	3.91	A+	$	10,320	4.04	A+

(1) The fair value by segment of our fixed maturities, cash and cash equivalents and fixed maturities included in funds held-directly managed portfolios does not include the carrying value of cash and cash equivalents within our funds held-directly managed portfolios.

(2) The average duration calculation includes cash and cash equivalents, short-term investments and fixed maturities, as well as the fixed maturities and cash and cash equivalents within our funds held-directly managed portfolios.

(3) The average credit rating calculation includes cash and cash equivalents, short-term investments, fixed maturities and the fixed maturities within our funds held - directly managed portfolios.

The overall decrease in the balance of our fixed maturities and cash and cash equivalents of $587 million when comparing March 31, 2024 to December 31, 2023 was primarily driven by the impact of net paid losses.

As of both March 31, 2024 and December 31, 2023, our fixed maturities and cash and cash equivalents had an average credit quality rating of A+ .

As of March 31, 2024 and December 31, 2023, our fixed maturities that were non-investment grade (i.e. rated lower than BBB- and non-rated securities) comprised $506 million, or 5.6%, and $456 million, or 4.8%, of our total fixed maturities portfolio, respectively.

General and Administrative Expenses for the Three Months Ended March 31, 2024 and 2023

The below chart is in millions of U.S. dollars.

Three Months Ended March 31, 2024 versus 2023: The $2 million decrease in general and administrative expenses was primarily driven by a decrease in lower professional fees, partially offset by increases in salaries and benefits and other expenses.

Item 2 | Management's Discussion and Analysis | Non-GAAP Financial Measures

Non-GAAP Financial Measures

In addition to our key financial measures presented in accordance with GAAP, we present other non-GAAP financial measures that we use to manage our business, compare our performance against prior periods and against our peers, and as performance measures in our incentive compensation program.

These non-GAAP financial measures provide an additional view of our operational performance over the long-term and provide the opportunity to analyze our results in a way that is more aligned with the manner in which our management measures our underlying performance.

The presentation of these non-GAAP financial measures, which may be defined and calculated differently by other companies, is used to enhance the understanding of certain aspects of our financial performance. It is not meant to be considered in isolation, superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.

Some of the adjustments reflected in our non-GAAP measures are recurring items, such as the exclusion of adjustments to net realized (gains)/losses and fair value changes on fixed maturity investments recognized in our statements of operations, the fair value of certain of our loss reserve liabilities for which we have elected the fair value option, and the amortization of fair value adjustments.

Management makes these adjustments in assessing our performance so that the changes in fair value due to interest rate movements, which are applied to some but not all of our assets and liabilities as a result of preexisting accounting elections, do not impair comparability across reporting periods.

It is important for the readers of our periodic filings to understand that these items will recur from period to period.

However, we exclude these items for the purpose of presenting a comparable view across reporting periods of the impact of our underlying claims management and investments without the effect of interest rate fluctuations on assets that we anticipate to hold to maturity and non-cash changes to the fair value of our reserves.

Similarly, our non-GAAP measures reflect the exclusion of certain items that we deem to be nonrecurring, unusual or infrequent when the nature of the charge or gain is such that it is not reasonably likely that such item may recur within two years, nor was there a similar charge or gain in the preceding two years. This includes adjustments related to bargain purchase gains on acquisitions of businesses, net gains or losses on sales of subsidiaries, net assets of held for sale or disposed subsidiaries classified as discontinued operations and other items that we separately disclose.

The following table presents more information on each non-GAAP measure. The results and GAAP reconciliations for these measures are set forth further below.

Non-GAAP Measure	Definition	Purpose of Non-GAAP Measure over GAAP Measure
Fully diluted book value per ordinary share	Total Enstar ordinary shareholders' equity Divided by Number of ordinary shares outstanding, adjusted for: -the ultimate effect of any dilutive securities (which include restricted shares, restricted share units, directors’ restricted share units and performance share units) on the number of ordinary shares outstanding	Increases the number of ordinary shares to reflect the exercise of equity awards granted but not yet vested as, over the long term, this presents both management and investors with a more economically accurate measure of the realizable value of shareholder returns by factoring in the impact of share dilution. We use this non-GAAP measure in our incentive compensation program.

Item 2 | Management's Discussion and Analysis | Non-GAAP Financial Measures

Adjusted return on equity (%)	Adjusted operating income (loss) attributable to Enstar ordinary shareholders divided by adjusted opening Enstar ordinary shareholder's equity	Calculating the operating income (loss) as a percentage of our adjusted opening Enstar ordinary shareholders' equity provides a more consistent measure of the performance of our business by enabling comparison between the financial periods presented. We eliminate the impact of fair value changes and net realized (gains) losses on fixed maturities and funds held-directly managed and the change in fair value of insurance contracts for which we have elected the fair value option, as:  •we typically hold most of our fixed maturities until the earlier of maturity or the time that they are used to fund any settlement of related liabilities which are generally recorded at cost; and  •removing the fair value option improves comparability since there are limited acquisition years for which we elected the fair value option.   Therefore, we believe that excluding their impact on our net income improves comparability of our core operational performance across periods.     We include fair value adjustments as non-GAAP adjustments to the adjusted operating income (loss) attributable to Enstar ordinary shareholders as they are non-cash charges that are not reflective of the impact of our claims management strategies on our loss portfolios.  We eliminate the net gain (loss) on the purchase and sales of subsidiaries and net income from discontinued operations, as these items are not indicative of our ongoing operations.    We use this non-GAAP measure in our incentive compensation program.
Adjusted operating income (loss) attributable to Enstar ordinary shareholders (numerator)	Net income (loss) attributable to Enstar ordinary shareholders, adjusted for: -fair value changes and net realized (gains) losses on fixed maturities and funds held-directly managed, -change in fair value of insurance contracts for which we have elected the fair value option (1), -amortization of fair value adjustments, -net gain/loss on purchase and sales of subsidiaries (if any), -net income from discontinued operations (if any), -tax effects of adjustments, and -adjustments attributable to noncontrolling interests
Adjusted opening Enstar ordinary shareholders' equity (denominator)	Opening Enstar ordinary shareholders' equity, less: -fair value changes on fixed maturities and funds held-directly managed, -fair value of insurance contracts for which we have elected the fair value option (1), -fair value adjustments, and -net assets of held for sale or disposed subsidiaries classified as discontinued operations (if any)

Item 2 | Management's Discussion and Analysis | Non-GAAP Financial Measures

Adjusted run-off liability earnings (%)	Adjusted PPD divided by average adjusted net loss reserves.	Calculating the RLE as a percentage of our adjusted average net loss reserves provides a more meaningful and comparable measurement of the impact of our claims management strategies on our loss portfolios across acquisition years and also to our overall financial periods.  We use this measure to evaluate the impact of our claims management strategies because it provides visibility into our ability to settle our claims obligations for amounts less than our initial estimate at the point of acquiring the obligations.     The following components of periodic recurring net incurred losses and LAE and net loss reserves are not considered key components of our claims management performance for the following reasons:  •Prior to the settlement of the contractual arrangements, the results of our Legacy Underwriting segment were economically transferred to a third party primarily through use of reinsurance and a Capacity Lease Agreement(3); as such, the results were not a relevant contribution to Adjusted RLE, which is designed to analyze the impact of our claims management strategies(2);   •The change in fair value of insurance contracts for which we have elected the fair value option(1) has been removed to support comparability between the two acquisition years for which we elected the fair value option in reserves assumed and the acquisition years for which we did not make this election (specifically, this election was only made in the 2017 and 2018 acquisition years and the election of such option is irrevocable); and •The amortization of fair value adjustments are non-cash charges that obscure our trends on a consistent basis. We include our performance in managing claims and estimated future expenses on our defendant A&E liabilities because such performance is relevant to assessing our claims management strategies even though such liabilities are not included within the loss reserves. We use this measure to assess the performance of our claim strategies and part of the performance assessment of our past acquisitions.
Adjusted prior period development (numerator)	Prior period net incurred losses and LAE, adjusted to: Remove: -Legacy Underwriting(2) operations -amortization of fair value adjustments, -change in fair value of insurance contracts for which we have elected the fair value option (1), and Add: -the reduction/(increase) in estimates of net ultimate liabilities and reduction in estimated future expenses of our defendant A&E liabilities.
Adjusted net loss reserves (denominator)	Net losses and LAE, adjusted to: Remove: -Legacy Underwriting(2) net loss reserves -current period net loss reserves -net fair value adjustments associated with the acquisition of companies, -the fair value adjustments for contracts for which we have elected the fair value option (1) and Add: -net nominal defendant A&E liability exposures and estimated future expenses.
Adjusted total investment return (%)	Adjusted total investment return (dollars) recognized in net income for the applicable period divided by period average adjusted total investable assets.	Provides a key measure of the return generated on the capital held in the business and is reflective of our investment strategy. Provides a consistent measure of investment returns as a percentage of all assets generating investment returns. We adjust our investment returns to eliminate the impact of the change in fair value of fixed maturities (both credit spreads and interest rates), as we typically hold most of these investments until the earlier of maturity or used to fund any settlement of related liabilities which are generally recorded at cost.
Adjusted total investment return ($) (numerator)	Total investment return (dollars), adjusted for: -fair value changes in fixed maturities, trading and funds held-directly managed; and -unrealized (gains) losses on fixed maturities, AFS included within OCI, net of reclassification adjustments and excluding foreign exchange.
Adjusted average aggregate total investable assets (denominator)	Total average investable assets, adjusted for: -net unrealized (gains) losses on fixed maturities, AFS included within AOCI -fair value changes on fixed maturities, trading and funds held - directly managed

Results of Operations by Segment - For the Three Months Ended March 31, 2024 and 2023

Effective January 1, 2024, our business is organized into two reportable segments: (i) Run-off and (ii) Investments. In addition, our Corporate and other activities, which do not qualify as an operating segment, include income and expense items that are not directly attributable to our reportable segments and activities from the former Assumed Life and Legacy Underwriting reportable segments.

Effective January 1, 2024, Assumed Life and Legacy Underwriting are no longer reportable segments as they ceased all business activities following the series of commutation and novation transactions in Enhanzed Re and the settlement of the arrangements between SGL No. 1, Arden, and Atrium. Any residual activities of the former Assumed Life and Legacy Underwriting reportable segments will be prospectively included within our Corporate and other activities (all of which are expected to be immaterial). See Note 2 to the consolidated financial statements for additional information.

The following is a discussion of our results of operations by segment.

Overall Results

Three Months Ended March 31, 2024 versus 2023: Net loss from our Run-off segment was $11 million compared to net loss of $5 million in the comparative quarter, primarily due to:

•A $10 million decrease in favorable PPD in the current quarter, mainly driven by a $9 million increase in the reduction in estimates of net ultimate losses in the comparative quarter.

◦During the first quarter of 2024, the net favorable development was primarily due to favorable development on our Professional Indemnity/Directors and Officers line of business of $29 million driven by favorable claims experience and favorable development on our Asbestos line of business of $24 million resulting from actuarial analysis. These were partially offset by adverse development on our General Casualty line of business of $18 million driven by adverse claims experience and adverse development on our Environmental line of business of $25 million due to results from actuarial reviews in the period.

◦In comparison, during the first quarter of 2023 we recognized favorable development of $11 million on our workers’ compensation line of business as a result of favorable claims experience, most notably in the 2021 acquisition year.

•A net favorable change in current period net incurred losses and LAE and acquisition costs of $6 million.

Overall Results

Three Months Ended March 31, 2024 versus 2023: Net income from our Investments segment was $224 million for the three months ended March 31, 2024 compared to net income of $344 million for the three months ended March 31, 2023. The variance of $120 million was primarily due to:

•a decrease in the gain from fair value changes in fixed maturities of $78 million, primarily as a result of increases in interest rates across U.S., U.K. and European markets in the current period, in comparison to decreases in interest rates in the comparative period;

•fair value change in other investments, including equities, of $104 million, compared to $147 million in the comparative period. The decrease of $43 million was primarily driven by:

◦a decrease in gain in the fair value change in other investments of $18 million for the three months ended March 31, 2024, primarily driven by an unfavorable variance in the fair value change of an embedded derivative in relation to the Aspen LPT, partially offset by increases in the fair value change related to CLO equity funds, private equity funds, real estate funds and high yield bond and loan funds relative to the comparative quarter; and

◦a decrease in the gain in fair value changes in equities of $16 million for the three months ended March 31, 2024, largely as a result of the reduced amount of equities within the investment portfolio relative to the comparative quarter.

•an increase in our net investment income of $4 million, which is primarily due to the reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed over the past 12 months and

the impact of rising interest rates on the $3.1 billion of our average fixed maturities outstanding during the current period that are subject to floating interest rates. Our floating rate investments generated net investment income of $58 million, an increase of $2 million in comparison to the comparative quarter.

(2) As of March 31, 2024, we own 24.6% of the common shares in Monument Re. We converted all of our preferred shares in Monument Midco to common shares in Monument Re on January 2, 2024. As of December 31, 2023, we owned 20.0% of the common shares in Monument Re as well as preferred shares in Monument Midco which had fixed dividend yields (where declared) and whose balances were included in the Investment amount.

Carrying Value and (Loss) Income from Equity Method Investments

The carrying value of our equity method investments decreased from December 31, 2023 primarily due to $5 million in loss from equity method investments for the three months ended March 31, 2024, which included a $30 million loss from our equity method investment in Monument, offset by earnings of $26 million from our equity method investment in Core Specialty.

Item 2 | Management's Discussion and Analysis | Results of Operations by Segment | Assumed Life Segment

Assumed Life Segment

The Assumed Life segment consisted of life and property aggregate excess of loss (catastrophe) business relating to Enhanzed Re.

During 2022, Enhanzed Re entered into a Master Agreement, through which we completed a series of commutation and novation agreements that allowed us to unwind Enhanzed Re’s operations in an orderly manner.

Transactions completed in the fourth quarter of 2022 were recognized in the first quarter of 2023, including the novation of our reinsurance of a closed block of life annuity policies to Monument Re and the repurchase of the remaining 24.9% interest in Enhanzed Re from Allianz.

Overall Results

Three Months Ended March 31, 2023: Net income from our Assumed Life segment of $275 million for the three months ended March 31, 2023 was primarily due to the net gain recognized on the completion of the novation of the Enhanzed Re reinsurance of a closed block of life annuity policies.

The $275 million gain calculated as of the completion date of the novation, prior to noncontrolling interests, was comprised of three components:

•the reclassification benefit to income of $363 million from AOCI related to the settlement of the novated liabilities (in accordance with our adoption of ASU 2018-12, the discount rate assumption for our long-duration liabilities was required to be periodically adjusted for changes in interest rates, which had the effect of reducing our future policyholder benefit liabilities and increasing the net assets transferred in the novation);

•the loss of $39 million on the carrying value of the net assets of $133 million as of the closing date of the transaction in exchange for cash consideration of $94 million (as noted above, the retrospective adoption of ASU 2018-12 resulted in an increase in net assets which gave rise to the transactional loss prior to our realization of the $363 million reclassification benefit); and

•a deferral of a portion of the net gain, $49 million, to account for our preexisting 20% ownership interest in Monument Re, calculated from the total gain of $324 million less Allianz’s 24.9% interest equal to $81 million (the deferred gain will be amortized over the expected settlement period for the life annuity policies to account).

Our net income attributable to Enstar was further reduced by $81 million, the amount attributable to Allianz’s 24.9% noncontrolling interest in Enhanzed Re at the time of the transaction. This amount has been recorded within our “Corporate and other activities”.

Our total first quarter 2023 net income attributable to Enstar from this novation transaction was $194 million.

Item 2 | Management's Discussion and Analysis | Results of Operations by Segment | Legacy Underwriting Segment

Legacy Underwriting Segment

The former Legacy Underwriting segment previously consisted of direct underwriting activities.

Overall Results

Three Months Ended March 31, 2023:

The Legacy Underwriting segment results comprised of SGL No.1 Limited’s (“SGL No.1”) 25% gross share of the 2020 and prior underwriting years of Atrium’s Syndicate 609 at Lloyd’s, less the impact of reinsurance agreements with Arden and a Syndicate 609 Capacity Lease Agreement with Atrium 5 Limited.

The contractual arrangements between SGL No. 1, Arden and Atrium relating to the reinsurance agreements and the Capacity Lease Agreement settled in the second quarter of 2023 for the economic benefit of Atrium, and there was no net retention by Enstar. As a result of the settlement, we did not record and do not expect to record any transactions in the Legacy Underwriting segment in 2023 and 2024, respectively.

Overall Results

Three Months Ended March 31, 2024 versus 2023: Net loss attributable to Enstar ordinary shareholders from our Corporate and other activities was $94 million and $190 million for the three months ended March 31, 2024 and 2023, respectively, primarily due to:

•a decrease in net income attributable to noncontrolling interests of $86 million, that was primarily a result of attributing $81 million of the gain on novation of the Enhanzed Re reinsurance closed block of life annuity policies to Allianz’s 24.9% equity interest in Enhanzed Re at the time of the transaction, in the comparative quarter; and

•changes in the fair value of the 2017 and 2018 portfolios where we elected the fair value option which resulted in a $4 million reduction in liabilities in the first quarter of 2024 primarily driven by an increase in U.K. corporate bond yields during the first quarter of 2024. The corporate bond yields, which form a component of the discount rate used to calculate the fair value of the liabilities, are matched to the original currencies of the underlying loss portfolios, of which GBP is the predominant currency for those portfolios that we have elected to measure at fair value using the fair value option. In comparison, we recognized a $20 million increase of such liabilities in the first quarter 2023 due to a decline in interest rates; partially offset by

•An increase in the amortization of net deferred charge assets of $13 million, driven by an increase in net DCA balances as a result of transactions completed subsequent to March 31, 2023.

Current Outlook

Run-off Outlook

Transactions

On April 30, 2024, one of our wholly owned subsidiaries reached an agreement for a loss portfolio transfer with a subsidiary of SiriusPoint Ltd. (“SiriusPoint”) to reinsure a portfolio of workers compensation business covering underwriting years 2018 to 2023. SiriusPoint will cede $400 million of net reserves and our subsidiary will provide $200 million of additional cover in excess of the ceded reserves. The closing of the transaction is subject to regulatory approval and other closing conditions.

We continue to evaluate transactions in our active pipeline including LPTs, ADCs, and other transaction types including acquisitions. We seek opportunities to execute on creative and accretive transactions by offering innovative capital release solutions that enable our clients to meet their capital and risk management objectives.

Should we execute additional transactions, our mix of loss reserves by line of business, asset mix and both rate and timing of earnings may be impacted in the medium to long term.

Seasonality

We complete most of our annual loss reserve studies in the fourth quarter of each year and, as a result, tend to record the largest movements, both favorable and adverse, to net incurred losses and LAE in this period.

In the interim periods where a reserve study has not been completed, we perform quarterly reviews to ascertain whether changes to claims paid or case reserves have varied from our expectations developed during the last annual reserve review. In this event, we consider the timing and magnitude of the actual versus expected development, and we may record an interim adjustment to our recorded reserves if, and when, warranted.

Investment Outlook

We expect global financial markets to remain uncertain throughout 2024 due to the lagged impact of higher interest rates and tighter financial conditions, a potential economic recession, resilient inflation, US Presidential elections and the macroeconomic effects of ongoing geopolitical conflicts and tensions.

Market expectations around the future path of interest rates will represent a continued source of volatility, as global central banks attempt to engineer a soft landing by normalizing interest rates while closely monitoring inflation. If interest rates rise and/or credit spreads widen, we may recognize unrealized losses and fair value changes on our fixed maturities and incur a higher rate of borrowing and interest costs if we renew or borrow under credit facilities in the current environment.

Despite this, elevated interest rates can represent an opportunity for us in the medium to long term, notably;

•As of March 31, 2024, we hold 17.4% of our portfolio, or $3.1 billion, in fixed maturity investments with floating interest rates which, should interest rates remain elevated, would be accretive to future investment book yields. We have earned $58 million and $56 million of net investment income from our floating rate investments for the three months ended March 31, 2024 and 2023, respectively, which were generally indexed to LIBOR1 through June 30, 2023 and SOFR thereafter.

•Higher interest rates have provided us with the opportunity to reinvest at higher yields as our securities mature or as we invest a significant portion of consideration received from new business in fixed maturities.

We expect that the cumulative unrealized losses and fair value changes we have recognized on our fixed maturities since 2022 will be recouped as these assets get closer to their maturity and the prices pull to par, assuming we do not, or are otherwise not required to, sell such investments prior to maturity. We may also undertake tactical repositioning of our portfolio as opportunities arise to achieve better alignment with our investment strategy, rather than waiting for certain fixed maturities to pull to par, which may result in the recognition of previously unrealized losses within our income statement with a corresponding reclassification adjustment in other comprehensive income. Such adjustments would be neutral to equity since the unrealized losses are recorded as a component of

1 LIBOR was ceased on June 30, 2023 and replaced by the Secured Overnight Financing Rate (“SOFR”).

Item 2 | Management's Discussion and Analysis | Current Outlook

accumulated other comprehensive income. Any investment repositioning may also have a corresponding impact to our investment book yield.

We expect global equity markets to remain volatile in 2024, and this, combined with our reporting lag on certain investments, may impact the valuation of our risk investments. We invest in public and private assets, which may vary in the magnitude of their exposure to any potential economic recession and other macroeconomic factors.

Despite these challenges, we remain committed to our strategic asset allocation and expect our investments to provide attractive risk adjusted returns and diversification benefits over the medium to long term.

Inflation

We continue to monitor the inflationary impacts resulting from pandemic-related government stimulus and labor force supply pressures on our loss cost trends.

Commencing in 2021, economic inflation rose significantly before peaking in mid-2022 and returning to low single digits in late 2023 and early 2024. During this period our net loss reserves have not been significantly impacted by these inflationary pressures.

Social inflation has been a persistent headwind for the industry for some time. We continue to monitor and seek to actively resolve claims in difficult judicial districts. We closely follow these trends and proactively set appropriate reserves.

As described above, global economic policy responses to inflation have contributed to increases in interest rates, which, in the short term, have had a significant impact on our investments, in particular our fixed maturities. Any further rise in interest rates will have further negative impacts on our fixed maturities in the form of unrealized losses and fair value changes.

There remains uncertainty around the future of inflation. We continue to monitor liquidity, capital and the potential earnings impact of these changes but remain focused on medium to long term asset allocation decisions.

We expect to continue to benefit from our allocation to investments with inflationary pass-through components, including investments in private equity, private credit, real estate, and infrastructure asset classes.

Inflation, tight labor conditions and higher service costs continue to put pressure on wages and prices, which could impact our general and administrative expenses as we remain focused on being a competitive employer in our market.

Geopolitical Conflicts

Heightened geopolitical conflicts, including the Russian invasion of Ukraine and the more recent conflicts in the Middle East, are directly and indirectly (through comprehensive sanctions regimes) contributing to increased commodity prices, disrupted supply chains, global financial market volatility and significant industry losses.

We continue to monitor our direct investment and underwriting risks and our acquisition pipeline as a result of these ongoing conflicts. To date, we are not aware of operational disruption to us or our third party service providers as a result of these conflicts, and we have not identified any significant direct impacts from these events. We also continue to monitor for, and respond to, all changes in the global sanctions regime, updating our procedures accordingly.

Minimum Corporate Income Tax

In December 2021, the OECD released the final model rules on Pillar II, an initiative proposing a global minimum tax rate of 15% designed to ensure large multinational enterprises pay a minimum level of tax on the income arising in each jurisdiction where they operate. We have several subsidiaries in jurisdictions that have enacted, or intend to enact, Pillar II legislation, including particularly the U.K., Australia and Belgium.

In response to Pillar II initiatives, the government of Bermuda enacted a 15% corporate income tax in December 2023 that will become effective January 1, 2025. Based on our substantial operations in Bermuda, we expect a meaningful portion of our income will be subject to the Bermuda corporate income tax. However, the Bermuda Corporate income tax will mitigate the impact of Pillar II.

Uses of Cash During the Three Months Ended March 31, 2024:

•We paid $9 million of cash dividends on our Series D and E Preferred Shares; and

•We paid $32 million of interest coupon payments on our Publicly Issued Notes.

As of March 31, 2024 we had $450 million of cash and cash equivalents, excluding restricted cash, that supports (re)insurance operations. Included in this amount was $234 million held by our foreign subsidiaries outside of Bermuda.

We closed 2023 with an estimated solvency capital ratio of 195%. Based upon our strong financial fundamentals and funding sources available to us, we continue to believe we have access to adequate liquidity and capital resources to meet business requirements under current market conditions and reasonably possible stress scenarios for the foreseeable future. We continuously monitor our liquidity and capital positions and adjust as required by market conditions. The following represent our total capitalization and capitalization attributable to Enstar as of March 31, 2024 and December 31, 2023.

Under the eligible capital rules of the Bermuda Monetary Authority (“BMA”), our Preferred Shares qualify as Tier 2 capital when considering the Bermuda Solvency Capital Requirements (“BSCR”).

For purposes of the financial covenants in our credit facilities, total debt excludes hybrid capital (defined as our Junior Subordinated Notes) not exceeding 15% of total capital attributable to Enstar. As of March 31, 2024, we were in compliance with the financial covenants in our credit facilities.

Item 2 | Management's Discussion and Analysis | Liquidity and Capital Resources

Liquidity and Capital Resources of Holding Company and subsidiaries

Holding Company Liquidity

We conduct substantially all of our operations through our subsidiaries. As such, the potential sources of liquidity to Enstar as a holding company consist of cashflows from our subsidiaries, including dividends, advances and loans, and interest income on loans to our subsidiaries. We have available borrowing capacity under our revolving credit facility, and we have obtained funding through the issuance of senior notes and preferred shares. The holding company also guaranteed our Junior Subordinated Notes issued by one of our subsidiaries in prior years.

As of March 31, 2024, we had $800 million of available unutilized capacity under our unsecured revolving credit agreement, which expires in May 2028. We may request additional commitments under the facility up to an aggregate amount of $200 million, which the existing lenders, in their discretion, or new lenders, may provide. To date, we have not requested any additional commitments under the facility.

We use cash to fund new acquisitions of companies. We also utilize cash for our operating expenses associated with being a public company and to pay dividends on our preferred shares and interest and principal on loans from subsidiaries and debt obligations, including loans under our credit facilities, our Senior Notes and our Junior Subordinated Notes.

We may, from time to time, raise capital from the issuance of equity, debt or other securities as we continuously evaluate our strategic opportunities. We filed an automatic shelf registration statement in March 2023 with the SEC to allow us to conduct future offerings of certain securities, if desired, including debt, equity and other securities.

As we are a holding company and have no substantial operations of our own, our assets consist primarily of investments in subsidiaries and our loans and advances to subsidiaries. Dividends from our (re)insurance subsidiaries are restricted by (re)insurance laws and regulations, as described below. The ability of all of our subsidiaries to make distributions and transfers to us may also be restricted by, among other things, other applicable laws and regulations and the terms of our credit facilities and our subsidiaries' bank loans and other issued debt instruments.

Based on our group's current corporate structure with a Bermuda domiciled parent company and the jurisdictions in which we operate, if the cash and cash equivalents held by our foreign subsidiaries were to be distributed to us, as dividends or otherwise, such amount would not be subject to incremental income taxes; however, in certain circumstances withholding taxes may be imposed by some jurisdictions, including by the United States.

Based on existing tax laws, regulations and our current intentions, there were no accruals as of March 31, 2024 for any material withholding taxes on dividends or other distributions.

Sources and Uses of Cash

Cash and cash equivalents decreased by $70 million during the three months ended March 31, 2024, which was largely due to cash used in operating and financing activities of $168 million and $8 million, respectively, partially offset by cash provided by investing activities of $102 million.

Cash and cash equivalents decreased by $187 million during the three months ended March 31, 2023, which was largely due to cash used in financing activities of $349 million, partially offset by cash provided by operating activities and investing activities of $70 million and $94 million, respectively.

Analysis of Sources and Uses of Cash

Operating Cash Flow Activities

2024 vs 2023: Cash used in operating activities of $168 million for the three months ended March 31, 2024 was driven by net paid losses of $670 million, partially offset by net sales and maturities of trading securities of $66 million, $161 million from receipt of net investment income and other sources of $275 million, which was largely generated by the release of funds held balances to cover net paid claims on certain portfolios. In comparison, cash provided by operating activities of $70 million for the three months ended March 31, 2023 was driven by net sales and maturities of trading securities of $323 million and other sources of $214 million, which was largely generated by the release of funds held balances to cover net paid claims on certain portfolios, net investment income received of $116 million, and cash consideration for the Enhanzed Re gain on novation of $94 million. These net inflows were partially offset by net paid losses of $677 million.

Investing Cash Flow Activities

2024 vs 2023: Cash provided by investing activities of $102 million for the three months ended March 31, 2024 was primarily due to net sales of fixed maturities, AFS of $184 million, partially offset by net purchases of other investments of $83 million. In comparison, cash provided by investing activities of $94 million for the three months ended March 31, 2023 was primarily due to net sales of fixed maturities, AFS of $147 million, partially offset by net purchases of other investments of $54 million.

Financing Cash Flow Activities

2024 vs 2023: Cash used in financing activities of $8 million for the three months ended March 31, 2024 was primarily driven by the payment of preferred share dividends of $9 million. In comparison, cash used in financing activities of $349 million for the three months ended March 31, 2023 was largely driven by share repurchases of $340 million, as a result of our strategic repurchase of our non-voting convertible ordinary shares during the first quarter of 2023.

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      83

Item 2 | Management's Discussion and Analysis | Liquidity and Capital Resources

U.S. Finance Company Liquidity

Enstar Finance is a wholly-owned finance subsidiary under which we have issued our Junior Subordinated Notes. Similar to our holding company, Enstar Finance is dependent upon funds from other subsidiaries to pay any amounts due under the Junior Subordinated Notes in the form of distributions or loans, which may be restricted by, among other things, other applicable laws and regulations and the terms of our credit facilities and our subsidiaries’ bank loans and other issued debt instruments.

Liquidity in Operating Companies

We expect that our operating companies will generate sufficient liquidity, together with our existing capital base and cash and investments acquired and from new business transactions, to meet cash requirements and to operate our business.

Sources of funds to our operating companies primarily consist of cash and investment portfolios acquired on the completion of acquisitions and new business, investment income earned, proceeds from sales and maturities of investments and collection of reinsurance recoverables. We also collect small amounts of premiums and fee and commission income.

Cash balances acquired upon the purchase of (re)insurance companies are classified as cash provided by investing activities, whereas cash from new business is classified as cash provided by operating activities.

The primary uses of funds by our operating companies are claims payments, investment purchases, operating expenses and collateral requirements.

The ability of our (re)insurance subsidiaries to pay dividends and make other distributions is limited by the applicable laws and regulations of the jurisdictions in which our (re)insurance subsidiaries operate, including Bermuda, the United Kingdom, the United States, Australia and Continental Europe, which subject these subsidiaries to significant regulatory restrictions.

These laws and regulations require, among other things, certain of our (re)insurance subsidiaries to maintain minimum capital requirements and limit the amount of dividends and other payments that these subsidiaries can pay to us, which in turn may limit our ability to pay dividends and make other payments.

As of March 31, 2024, to our knowledge, all of our (re)insurance subsidiaries’ capital requirement levels were in excess of the minimum levels required for their respective regulatory jurisdictions.

Our subsidiaries' ability to pay dividends and make other forms of distributions may also be limited by our repayment obligations under certain of our outstanding credit facility agreements and other debt instruments. Variability in ultimate loss payments and collateral amounts required may also result in increased liquidity requirements for our subsidiaries.

Debt Obligations

We utilize debt financing and loan facilities primarily for funding acquisitions and significant new business, investment activities and, from time to time, for general corporate purposes.

Our debt obligations as of March 31, 2024 and December 31, 2023 were as follows:

Facility	Origination Date	Term	March 31, 2024		December 31, 2023
			(in millions of U.S. dollars)
4.95% Senior Notes due 2029	May 2019	10 years	$	496	$	496
3.10% Senior Notes due 2031	August 2021	10 years	496		496
Total Senior Notes			992		992
5.75% Junior Subordinated Notes due 2040	August 2020	20 years	346		345
5.50% Junior Subordinated Notes due 2042	January 2022	20 years	494		494
Total Junior Subordinated Notes			840		839
Total debt obligations			$	1,832	$	1,831

Under the eligible capital rules of the BMA, the Senior Notes qualify as Tier 3 capital and the Junior Subordinated Notes qualify as Tier 2 capital when considering the BSCR.

Enstar Group Limited | First Quarter 2024 | Form 10-Q                      84

Item 2 | Management's Discussion and Analysis | Liquidity and Capital Resources

We may from time to time seek to retire or purchase our outstanding debt through cash purchases, redemptions and/or exchanges for other securities, in open market purchases, privately negotiated transactions or otherwise. Any such repurchases, redemptions or exchanges will be dependent upon several factors, including our liquidity requirements, contractual restrictions, general market conditions and applicable regulatory, legal and accounting factors.

Credit Ratings

The following table presents our credit ratings as of May 2, 2024:

Credit ratings (1)	Standard and Poor’s	Fitch Ratings
Long-term issuer	BBB+ (Outlook: Stable)	BBB+ (Outlook: Stable)

(1) Credit ratings are provided by third parties, Standard & Poor’s and Fitch Ratings, and are subject to certain limitations and disclaimers. For information on these ratings, refer to the rating agencies’ websites and other publications.

Agency ratings are not a recommendation to buy, sell or hold any of our securities and may be revised or withdrawn at any time by the issuing organization. Each agency's rating should be evaluated independently of any other agency's rating2.

Contractual Obligations

Reserves for Losses and LAE

We generally attempt to match the duration of our investment portfolio to the duration of our general liability profile and generally seek to maintain investment portfolios that are shorter or of equivalent duration to the liabilities in order to provide liquidity for the settlement of losses and, where possible, to avoid having to liquidate longer-dated investments. The settlement of liabilities also has the potential to accelerate the natural payout of losses and policyholder benefits, which may require additional liquidity. As of March 31, 2024 and December 31, 2023, the weighted average estimated durations of our Run-off segment gross reserves for losses and LAE were 4.69 and 4.72 years, respectively.

Share Repurchases and Dividends

We believe that the best investment is in our business, by funding future transactions and meeting our financing obligations. We may choose to return value to shareholders in the form of share repurchases or dividends. To date, we have not declared any dividends on our ordinary shares. We may re-evaluate this strategy from time to time based on overall market conditions and other factors.

We have 16,000 Series D Preferred Shares with an aggregate liquidation value of $400 million and 4,400 Series E Preferred Shares with an aggregate liquidation value of $110 million. The dividends on both Series of Preferred Shares are non-cumulative and may be paid quarterly in arrears, only when, as and if declared.

Any payment of common or preferred dividends must be approved by our Board. Our ability to pay ordinary and preferred dividends is subject to certain restrictions.

Off-Balance Sheet Arrangements

As of March 31, 2024, we have entered into certain investment commitments and parental guarantees. We do not believe it is reasonably likely that these arrangements will have a material unplanned current or future effect on our financial condition as they are considered in normal course of business and on-going stress testing.

We also utilize unsecured and secured letters of credit3 (“LOCs”) and a deposit facility.

The following table represents our outstanding unfunded investment commitments and LOCs by duration as of March 31, 2024:

Exhibit 10.1

AMENDED AND RESTATED

EMPLOYMENT AGREEMENT

This Amended and Restated Employment Agreement (“Agreement”) is made by and between Enstar (US) Inc., a Delaware corporation(the “Company”),and Nazar Alobaidat (“Executive”). The Company is a subsidiary of Enstar Group Limited (collectively, with its subsidiaries, “Enstar”).

1.    Employment Period. The Company hereby continues to employ Executive for the period commencing on the date Executive signs this Agreement (the “Effective Date”) and ending on the date that Executive's employment with the Company terminates (“Termination Date”) pursuant to the provisions of this Agreement (“Employment Period”). This Agreement shall amend and restate in its entirety the current employment agreement between Executive and the Company dated as of September 9, 2016 (the “Original Agreement”) and shall expire, except for its surviving terms, on the Termination Date.

2.    Terms of Employment.

(a)    Position and Duties. During the Employment Period, Executive shall serve as Enstar’s Chief Investment Officer, with such duties, authority and responsibilities as are commensurate with such position and assigned by the Company and/or Enstar. During the Employment Period, Executive shall faithfully perform all of the duties and responsibilities for the position and shall devote his best efforts and full business time and attention to the business of Enstar. Executive shall directly report to Enstar’s Chief Executive Officer (“CEO”). Executive will principally work on a remote basis from his home in New Jersey, although it is understood that Executive may be required to work from or visit other offices and locations from time to time and that Executive’s position will require travel. Notwithstanding the foregoing, Executive may devote reasonable time to other professional activities, including without limitation participation in committees, professional associations, and board memberships, in each case so long as such activities are in accordance with the Code of Conduct and approved in advance in writing by Enstar’s CEO or the CEO’s designee.

(b)    Compensation.

(i)    Base Salary. During the Employment Period, Executive shall receive a base salary (“Base Salary”), initially effective April 1, 2023, at an annualized rate of $650,000, payable in accordance with the Company’s standard payroll practices in effect from time to time (the Company currently has 26 pay periods in a year) and subject to applicable deductions and withholdings. Executive acknowledges that he is an exempt employee and, accordingly, that he is not entitled to overtime pay regardless of the number of hours required to complete his duties hereunder. The Base Salary of Executive will be reviewed from time to time in accordance with the established procedures of the Company and/or Enstar for adjusting salaries for similarly situated employees and may be increased in the sole discretion of the Company and/or Enstar but not decreased without Executive’s consent. The Company’s annual salary review is currently conducted prior to April 30th of each year. If that schedule continues, Executive will first be eligible for a merit increase, if any, on or before April 30, 2024.

(ii)    Performance Bonus Plan. During the Employment Period, Executive will be eligible to participate in the Enstar annual discretionary performance bonus program in effect from time to time at a level commensurate with his position and in accordance with the policies and practices of Enstar in its sole discretion. The annual discretionary performance bonus program is administered by the Enstar Compensation Committee and subject to its discretionary review and approval each year, and therefore Enstar can only provide guidance that it expects Executive’s eligibility for future awards, beginning with respect to performance year 2023 (payable in calendar year 2024), to be based on a

“target” of one hundred twenty-five percent (125%) of Base Salary, which awards shall be assessed pursuant to Enstar financial performance objectives and individual performance objectives to be established by the Enstar Compensation Committee in its discretion. In all cases, actual bonus awards received, if any, are subject to vary. Payment of the performance bonus under the bonus program, if any, is not a wage, and is not earned or accrued or payable, until the date that it is actually tendered to Executive. Receipt of a bonus in one year does not guarantee a bonus in any other year. If awarded, any performance bonus shall be payable at such time as the Company pays annual bonuses generally to its employees, but in no event later than April 30th of the year following the year to which the performance bonus relates; provided, however, that the accrual and payment of any performance bonus is conditioned upon Executive being employed through the end of the applicable calendar year and, as of the date of payment, Executive (A) not having been previously terminated for Cause (as defined herein) and (B) not having received notice of a termination for Cause where such Cause is not subsequently cured.

(iii)    Annual Equity Incentives. During the Employment Period, Executive shall be eligible to continue to participate in the Enstar long-term incentive program in effect from time to time at a level commensurate with his position and in accordance with the policies and practices of Enstar. The long-term incentive program is administered by the Enstar Compensation Committee and subject to its discretionary review and approval each year, and therefore Enstar can only provide guidance that it expects Executive’s eligibility for future awards to be based on one-hundred percent (100%) of Base Salary annually, with the awards expected to be comprised of a combination of Restricted Stock Units (“RSUs”) pursuant to the terms and conditions of Enstar’s Amended and Restated 2016 Equity Incentive Plan (or any successor plan) (the “Equity Incentive Plan”) and approved forms of RSU award agreements, and Performance Stock Units (“PSUs”) pursuant to the terms and conditions of the Equity Incentive Plan and approved forms of PSU award agreements, in the proportion established by the Enstar Compensation Committee (which proportion is currently thirty percent (30%) RSUs and seventy percent (70%) PSUs, but is subject to change from time to time).

(iv)    Employee Benefit Plans. During the Employment Period, Executive shall be eligible to continue to participate in the Company’s group health and welfare insurance programs. These benefits are subject to change, with advance notice to Executive as required by law, in the Company’s discretion.

(v)    401(k) Plan. During the Employment Period, Executive shall be eligible to participate in the Company’s 401(k) plan (subject to plan eligibility requirements), as such plan is amended from time to time in the Company’s discretion. If Executive elects to participate in the Company’s 401(k) plan, and such plan provides for employee matching contributions during his participation, the Company will make matching contributions, in accordance with the terms of the Company’s plan then in effect. Enrollment elections will become effective as soon as administratively feasible.

(vi)    Paid Time Off. During the Employment Period, Executive shall be entitled to thirty (30) business days of paid time off (“PTO”) per calendar year in accordance with the Company’s PTO policy, as may be amended from time to time.

(vii)    Expenses. The Company shall reimburse Executive for reasonable business expenses incurred in the performance of his duties in accordance with the Company’s expense reimbursement guidelines, as may be amended from time to time.

(viii)    Deductions and Withholding. The Company shall deduct and withhold from any salary, benefits, and other compensation payable to Executive all federal, state, local, and other taxes and all other amounts as required by applicable law, rule or regulation.

(c)    Policies and Procedures. The employment relationship between the parties shall be governed by the general employment practices, policies, and procedures of Enstar, and Executive

2

agrees to comply with all of Enstar’s practices, policies, and procedures in effect and made available to him from time to time.

3.    Other Activities.

(a)    Activities. During the Employment Period, Executive shall not, without the prior written consent of the Company in its sole discretion as signed by a duly authorized officer of the Company, (i) engage in any employment other than with the Company, (ii) solicit the business of any client or customer of Enstar other than on behalf of the Company, and/or (iii) engage, directly or indirectly, in any other business activity (whether or not pursued for pecuniary advantage) that does or may be expected to interfere with the obligations of Executive under this Agreement or that might create a conflict of interest with Enstar.

(b)    No Conflict. Executive represents and warrants that his execution of this Agreement, his employment with the Company, and the performance of his duties under this Agreement has not violated and will not violate any obligations he may have to any former employer or other person or entity, including any obligations with respect to proprietary or confidential information of any such employer or other person or entity or with respect to non-competition or non-solicitation. By signing this Agreement, Executive confirms that he has not used or disclosed and that he will not use or disclose, for any purpose whatsoever, any confidential, proprietary, or trade secret information belonging to any former employer or other person or entity.

4.    Confidentiality Agreement and Intellectual Property. On or about the date his employment commenced, Executive signed the Company’s standard confidentiality agreement (the “Confidentiality Agreement”) in connection with initially being hired by the Company and such agreement shall remain in effect notwithstanding any other provision of this Agreement. Executive agrees to cooperate fully with Enstar, both during and after his employment with the Company, with respect to the procurement, maintenance, and enforcement of intellectual property rights in Enstar-related developments. Executive agrees to sign, both during and after the Employment Period, all papers, including without limitation copyright applications, patent applications, declarations, oaths, assignments of priority rights, and powers of attorney, which Enstar may deem necessary or desirable in order to protect its rights and interests in any Enstar-related development. If the Company is unable, after reasonable effort, to secure Executive’s signature on any such papers, Executive hereby irrevocably designates and appoints each officer of the Company as his agent and attorney-in-fact to execute any such papers on his behalf, and to take any and all actions as the Company may deem necessary or desirable in order to protect its rights and interests in any Company-related development. Executive hereby waives and irrevocably quitclaims to the Company or its designee any and all claims, of any nature whatsoever, which he now or hereafter has for infringement of any and all proprietary rights assigned to the Company or such designee.

5.    At-Will Employment; Termination without Cause by the Company.

(a)    At-Will Employment. The employment of Executive shall be “at-will” at all times hereunder, meaning that either the Company or Executive may terminate Executive’s employment at any time or for any reason, with or without Cause or with or without Good Reason, and subject only to applicable “notice” and severance provisions of this Section 5 and Section 6, notwithstanding any provision to the contrary contained in or arising from any statements, policies, or practices of the Company relating to the employment, discipline, or termination of its employees. This at-will employment relationship cannot be changed except in writing signed by Executive and a duly authorized officer of the Company other than Executive.

(b)    Termination without Cause by the Company. The Company may unilaterally terminate the employment of Executive without Cause, as defined in Section 7 immediately upon written notice. If Executive’s employment is terminated by the Company without Cause, then subject to

3

Executive’s signing (and non-revocation) of a separation agreement containing a plenary release of all claims in a form acceptable to the Company (a “Release”) within twenty-one (21) days of the Termination Date (or such shorter period as required by such Release), Executive shall be entitled to receive, in addition to all earned compensation through his Termination Date, the following without duplication (collectively, the “Severance Benefits”):

(i)    the greater of (A) salary continuation at Executive’s then-current base salary for twelve (12) months after the Termination Date or (B) payment of severance under the Enstar US Severance Plan existing at the time of Termination Date;

(ii)    a lump sum cash amount equal to Executive’s target bonus opportunity under the annual performance bonus program for the year in which Executive’s employment is terminated, pro-rated based on the ratio of the number of days of employment completed in the performance year through and including the Termination Date to the total number of days in the performance year; and

(iii)    subject to timely election and eligibility, Company-paid COBRA-continuation coverage for Executive and any eligible dependents for a period of up to 12 months after the Termination Date, at the same or substantially same coverage levels available during the last ninety (90) days of Executive’s active employment with the Company.

Notwithstanding the foregoing, all Severance Benefits not yet paid by March 15 of the calendar year following the Termination Date shall be paid in a lump sum on such March 15 or the first business day prior thereto. If Executive is terminated without Cause, any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder.

6.    Termination by Executive.

(a)    Resignation with Good Reason. Executive may terminate his employment with the Company with Good Reason, as defined in Section 6(c), by notifying the Company in writing within thirty (30) days after the initial existence of the event giving rise to Good Reason that Executive intends to terminate his employment with Good Reason, and if such Good Reason is not cured within thirty (30) days of such written notice to the Company (the “Cure Period”), by actually terminating employment no earlier than sixty (60) calendar days after the Cure Period ends (the “Good Reason Notice Period”), during which period, Executive shall continue to fulfill his obligations under this Agreement and assist with the transition of Executive’s duties. The Company shall have the option, in its sole discretion to ask the Executive to cease performing duties at any time prior to the end of the Good Reason Notice Period; provided, however, that should the Company exercise this option such exercise shall not be deemed a termination by the Company without Cause or an event giving rise to Good Reason. In the event Executive resigns for Good Reason, subject to Executive’s signing (and non-revocation) of a Release within twenty-one (21) days of the Termination Date (or such shorter period as required by such Release), Executive shall be entitled to receive the Severance Benefits, and any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder.

(b)    Resignation without Good Reason. Executive may terminate his employment with the Company at any time without Good Reason by providing six (6) months’ advance written notice to the Company (“Non-Good Reason Notice Period”). In the event of a resignation without Good Reason, Executive shall be entitled only to compensation and benefits earned and accrued up to and through the Termination Date. The Company shall have the option, in its sole discretion, to make Executive’s termination effective at any time prior to the end of such Non-Good Reason Notice Period. For clarity, should the Company exercise the option described in the foregoing sentence, such exercise shall not be deemed a termination by the Company without Cause or an event giving rise to Good Reason. For

4

clarity, this Section 6(b) is subject to Section 7(a), such that if Executive is terminated for Cause during the Non-Good Reason Notice Period, the terms of Section 7(a) hereof shall control.

(c)    Good Reason. For purposes of this Agreement, “Good Reason” means any of the following without Executive’s consent, and subject to the cure period in Section 6(a) above:

(i)    Material diminution in Executive’s title, duties or authority inconsistent with Executive’s position;

(ii)    No longer permitting Executive to work primarily remotely, other than relocating Executive’s principal place of employment to an office that is no more than a 90-minute commute from Executive’s residence at the Effective Date if Executive’s physical attendance is regularly required at such place, and except for required travel on Company business to an extent substantially consistent with Executive’s business travel obligations as of the date of relocation; or

(iii)    Any other action or inaction by Enstar that constitutes a material breach of the material terms and provisions of this Agreement or any other material agreement between Executive and Enstar.

(d)    New Equity Awards. Notwithstanding anything in this Agreement to the contrary, Executive shall not be entitled to receive any new equity incentive awards following his delivery of notice to the Company that he is resigning for Good Reason or that he is resigning without Good Reason.

7.    Other Terminations of Employment.

(a)    Termination for Cause. The Company may immediately terminate the employment of Executive for Cause upon the occurrence of any of the following events (each a “Cause”):

(i)    Conviction or plea to a felony or a crime involving fraud or misrepresentation;

(ii)    Indictment for a felony or a crime involving fraud, misrepresentation, or misconduct; provided, however, that in the event Executive is subsequently acquitted of such crime or the indictment is subsequently dismissed, any prior termination of Executive solely pursuant to this clause (ii) shall be treated as a termination without Cause;

(iii)    Failure by Executive to follow lawful instructions from Executive’s supervisor or the Board of Directors of the Company or Enstar following a reasonable opportunity to cure, if curable, within a time frame determined by the Company, but no less than twenty (20) days from such notice;

(iv)    Failure to perform Executive’s duties hereunder following written notice and a reasonable opportunity to cure, if curable, within a time frame determined by the Company, but no less than twenty (20) days from such notice;

(v)    Material gross neglect by Executive in the performance of his duties hereunder following written notice and a reasonable opportunity to cure, if curable, not to exceed twenty (20) days from such notice;

(vi)    Fraud or dishonesty in connection with the Executive’s employment or the performance of his duties;

(vii)    Breach of fiduciary duty related to the business or affairs of the Company or Enstar;

5

(viii)    Executive’s material breach of any written agreement with the Company or Enstar, including this Agreement and the Confidentiality Agreement, following written notice and a reasonable opportunity to cure, if curable, not to exceed twenty (20) days from such notice; or

(ix)    Willful misconduct that the Company reasonably believes to be materially harmful to the business, interests, or reputation of Enstar, including any material violation of any Enstar written policy; provided, however, that any right to cure hereunder shall not be applicable to two or more of the same or similar or related breaches, acts, or omissions.

In the event of a termination for Cause, the Company shall pay to Executive only the compensation to which Executive is entitled up through the Termination Date, subject to any other rights or remedies of the Company under law; and thereafter all obligations of the Company under this Agreement shall cease. For clarity, Executive shall not be entitled to Severance Benefits in the event of a termination for Cause.

(b)    By Death. The employment of Executive shall terminate automatically upon Executive’s death. The Company shall pay and provide to Executive’s beneficiaries or estate, as appropriate, any compensation to which Executive would have been entitled up through the date of death, and any and all RSUs and PSUs awarded to Executive prior to his death shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder. Thereafter all obligations of the Company under this Agreement shall cease. Nothing in this Section shall affect any entitlement of the heirs or devisees of Executive to the benefits of any life insurance plan or policy or other applicable benefits. For clarity, Executive shall not be entitled to Severance Benefits in the event of a termination pursuant to this Section.

(c)    By Disability. If Executive becomes eligible for the long term disability benefits of the Company or if, in the reasonable opinion of the Board of Directors of the Company, Executive is unable to carry out the responsibilities and functions of the position held by Executive by reason of any physical or mental impairment for more than ninety (90) consecutive days or more than one hundred and twenty (120) days in any twelve (12) month period, then, to the extent not prohibited by law, the Company may terminate Executive’s employment. If the Company so terminates Executive’s employment, the Company shall pay and provide to Executive (i) all compensation to which Executive is entitled up through the Termination Date, (ii) salary continuation at Executive’s then-current base salary for six (6) months after the Termination Date minus any disability payments received by Executive from disability insurance policies paid for by the Company, and (iii) a lump sum cash amount equal to Executive’s target bonus opportunity under the annual performance bonus program for the year in which Executive’s employment is terminated, pro-rated based on the ratio of the number of days of employment completed in the performance year through and including the Termination Date to the total number of days in the performance year. Notwithstanding the foregoing, all such disability payments not yet paid by March 15 of the calendar year following the Termination Date shall be paid in a lump sum on such March 15 or the first business day prior thereto. In addition, upon termination of Executive’s employment pursuant to this Section, any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder. Thereafter all obligations of the Company under this Agreement shall cease. Nothing in this Section shall affect Executive’s rights under any disability plan or other applicable benefit plans or policies in which Executive is a participant. For clarity, Executive shall not be entitled to Severance Benefits in the event of a termination pursuant to this Section.

(d)    Termination without Cause or Resignation with Good Reason following Change in Control. If there should be a Change in Control (as defined in the Equity Incentive Plan), and on or within 12 months thereafter either: (i) Executive’s employment is terminated without Cause or (ii) Executive terminates his employment for Good Reason, then subject to Executive’s signing (and non-revocation) of a Release within twenty-one (21) days of the Termination Date (or such shorter period as required by such Release) and in lieu of any Severance Benefits to which Executive may have been entitled to receive under Section 5(b) or Section 6(a), Executive shall be entitled to receive in addition to all earned

6

compensation through his Termination Date, the following without duplication of amounts paid or benefits provided hereunder or otherwise in connection with the Change of Control (collectively, the “Change in Control Severance Benefits”):

(i)    the greater of (A) salary continuation at Executive’s then-current base salary for eighteen (18) months after the Termination Date or (B) payment of severance under the Enstar US Severance Plan existing at the time of Termination Date;

(ii)    a lump sum cash amount equal to Executive’s target bonus opportunity under the annual performance bonus program for the year in which Executive’s employment is terminated, pro-rated based on the ratio of the number of days of employment completed in the performance year through and including the Termination Date to the total number of days in the performance year; and

(iii)    subject to timely election and eligibility, Company-paid COBRA-continuation coverage for Executive and any eligible dependents for a period of up to 12 months after the Termination Date, at the same or substantially same coverage levels available during the last ninety (90) days of Executive’s active employment with the Company.

Notwithstanding the foregoing, all Change in Control Severance Benefits not yet paid by March 15 of the calendar year following the Termination Date shall be paid in a lump sum on such March 15 or the first business day prior thereto. Any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder.

8.    Return of Property. Upon termination of employment with the Company, Executive agrees to promptly return to the Company and not retain any and all property, equipment, documents, data, and materials of Enstar of any kind in the possession and/or control of Executive.

9.    Cooperation in Pending Work. Following any termination of Executive’s employment (or, during any notice period, if applicable), Executive shall reasonably cooperate with the Company and/or Enstar in all matters relating to the winding up of pending work on behalf of the Company and/or Enstar and the orderly transfer of work to other employees or contractors of the Company and/or Enstar. Executive shall also reasonably cooperate, at all times during and after Executive’s employment, in the defense of any action brought by any third party against the Company and/or Enstar that relates in any manner to Executive’s acts or omissions while employed by the Company or which concerns matters about which Executive has knowledge. The Company’s request for cooperation pursuant to this Section shall take into consideration Executive’s personal and business commitments and the amount of notice provided to Executive.  Except for any cooperation that occurs during an applicable notice period, the Company will reimburse Executive, in accordance with Company policy, for reasonable expenses and reasonable and necessary attorneys’ fees incurred as a result of Executive’s cooperation pursuant to this Section.

10.    Non-Solicitation. During the term of his employment with the Company and for a period of twelve (12) months immediately after the date his employment terminates for any reason (the “Non-Solicitation Period”), Executive agrees that Executive will not, directly or indirectly, (i) call upon, solicit, divert, or take away any of the clients, business, or business partners of the Company, or request or cause any of the above to abandon, cancel or terminate any part of their relationship with Enstar, or (ii) solicit, entice, or attempt to persuade any employee, agent, consultant, or independent contractor of Enstar to leave the service of such company for any reason or take any other action that may cause any such individual to terminate his relationship with Enstar.

11.    Non-Competition. During the term of his employment with the Company and for a period of twelve (12) months immediately after the date his employment terminates by reason of

7

termination for Cause by the Company or by reason of resignation by the Executive without Good Reason (the “Restriction Period”), Executive shall not, without the prior written permission of the Enstar Board, directly or indirectly engage in any Competitive Activity. The term “Competitive Activity” shall mean (i) entering the employ of, or rendering services to, any person, firm or corporation engaged in the insurance run-off business and/or the reinsurance run-off business (hereinafter defined as the “Business”); (ii) engaging in the Business for Executive’s own account or becoming interested in any such Business, directly or indirectly, as an individual, partner, shareholder, member, director, officer, principal, agent, employee, trustee, consultant, or in any other similar capacity; provided, however, nothing in this Section 11 shall prohibit Executive from owning, solely as a passive investment, 5% or less of the total outstanding securities of a publicly-held company. For the avoidance of doubt, the provisions of this Section 11 shall not apply in the event Executive’s employment with the Company is terminated without Cause or due to resignation with Good Reason. For the avoidance of doubt, nothing in this Section 11 shall prevent Executive from becoming employed during the Restriction Period with an insurance company that is not engaged in insurance run-off business or reinsurance run-off business.

12.    Injunctive Relief. Executive acknowledges that the remedy at law for any Executive breach or threatened breach of Sections 4, 8, 9, 10 or 11 this Agreement will be inadequate, and accordingly that the Company, in addition to all other available remedies (including without limitation seeking such damages as it has sustained by reason of such breach), shall be entitled, notwithstanding Section 13 hereof, to seek injunctive or any other appropriate form of equitable relief in a court of competent jurisdiction without being required to post a bond. Executive agrees and acknowledges that the Non-Solicitation Period and Restriction Period, respectively, shall be extended for one extra day for each day in which Executive is in breach of Sections 10 or 11, respectively.

13.    Alternative Dispute Resolution.

(a)    Arbitrable Claims. To ensure the rapid, economical, and private resolution of any disputes which may arise concerning the relationship between Executive and the Company, the parties hereby agree that any and all disputes, claims or controversies (collectively “disputes”) in any manner arising out of or relating to or in connection with Executive’s employment or termination of employment with the Company, including but not limited to any matter arising from or related to this Agreement or any breach, termination, enforcement, interpretation, or validity thereof (“Arbitrable Claims”), shall be resolved to the fullest extent not prohibited by law by final and binding arbitration administered by the American Arbitration Association or its successor (“AAA”) pursuant to its then applicable employment arbitration rules and procedures (“AAA Rules”); provided,however, that notwithstanding the foregoing or any contrary provision of this Agreement, this arbitration provision shall not be applicable to any dispute relating to (i) any of the ownership or scope or validity or enforceability of any patent, copyright, trade mark, trade secret or other intellectual property or intellectual property rights or the infringement or misappropriation or violation thereof or (ii) any demand for injunctive relief pursuant to Section 12 of this Agreement. Subject to the foregoing proviso, Arbitrable Claims shall include without limitation claims for breach of contract (express or implied), tort of any kind, employment discrimination (including harassment), as well as all claims based on any federal, state, or local law, statute, or regulation, including claims for employment discrimination or retaliation, which include, by way of example only, claims under Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act, the Americans with Disabilities Act, and any other similar federal laws or their comparable state or local counterparts.

(b)    Arbitration Procedures. The arbitration of Arbitrable Claims shall be in accordance with the AAA Rules and shall take place in New York, New York before a single neutral arbitrator, unless otherwise agreed by the parties. Arbitration shall be final and binding upon the parties and shall be the exclusive remedy for all Arbitrable Claims. Executive shall have the right to be represented by legal counsel at any arbitration proceeding. The arbitrator shall (i) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be available under applicable law in a court proceeding; (ii) have the authority to award attorneys’ fees

8

and costs to the prevailing party in any dispute submitted to arbitration; and (iii) issue a written statement signed by the arbitrator regarding the disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which the award is based. Either party may bring an action in court to compel arbitration under this Agreement, to enforce an arbitration award or to obtain temporary injunctive relief pending a judgment based on the arbitration award. Otherwise, neither party shall initiate or prosecute any lawsuit or administrative action in any manner related to any Arbitrable Claim. The Federal Arbitration Act shall govern the interpretation and enforcement of this provision.

(c)    Class Arbitration Waiver. Any arbitration will be conducted and resolved on an individual basis and not a class-wide, multiple plaintiff, or similar basis. Any arbitration will not be consolidated with any other arbitration proceeding involving any other person.

14.    Compliance with Section 409A of the Internal Revenue Code. Notwithstanding anything herein to the contrary:

(a)    As determined by the Company, to the extent any provision herein constitutes a “nonqualified deferred compensation plan” under Section 409A(d)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), which provides for the payment of compensation provides to Executive upon his “separation from service” under Section 409A(a)(2)(A)(i) of the Code, and Executive is a “specified employee” under Section 409A(a)(2)(B)(i) of the Code, then any such compensation or benefit otherwise payable to Executive shall be suspended and not be paid to Executive until the date that is six (6) months after the date of his separation from service and any amounts suspended during such six (6)-month period shall be paid once benefits commence. The right to any series of installment payments hereunder shall be treated for purposes of Section 409A of the Code as a right to a series of separate payments.

(b)    The provisions herein, and plans and arrangements referenced hereunder, are intended to comply with or be exempt from the applicable requirements of Section 409A of the Code and may be limited, construed, and interpreted in accordance with such intent. References in this Agreement to “termination of employment” or word to similar effect shall mean a “separation from service” as defined in final regulations promulgated under Section 409A of the Code. Notwithstanding anything herein to the contrary, (i) any provision hereunder that is inconsistent with Section 409A of the Code may be deemed to be amended to comply with Section 409A of the Code, and to the extent such provision cannot be amended to comply therewith, such provision may be null and void, and (ii) neither the Company, Enstar, any of their affiliates, or any person acting on any of their behalf shall be liable to Executive or any other person by reason of any acceleration of income or any additional tax (including any interest or penalties) asserted by reason of the failure of any payments or benefits to comply with or be exempt from Section 409A of the Code.

(c)    To the extent Executive is entitled to receive taxable reimbursements and/or in-kind benefits, the following provisions apply: (i) Executive shall receive such reimbursements and benefits for the period set forth in this Agreement and, if no such period is specified, Executive shall receive such reimbursements and benefits for the term of this Agreement, (ii) the amount of such reimbursements and benefits Executive receives in one year shall not affect amounts provided in any other year, (iii) such reimbursements must be made by the last day of the year following the year in which the expense was incurred, and (iv) such reimbursements and benefits may not be liquidated or exchanged for any other reimbursement or benefit.

(d)    No acceleration of any payment, including separation payments, shall be permitted if such acceleration would result in Executive being taxed under Section 409A of the Code.

15.    Section 280G of the Code. If any payment or benefit due under this Agreement, together with all other payments and benefits that Executive receives or is entitled to receive from the

9

Company, Enstar, or any of their subsidiaries, affiliates, or related entities, would (if paid or provided) constitute an “excess parachute payment” for purposes of Section 280G of the Code, the amounts otherwise payable and benefits otherwise due under this Agreement will either (i) be delivered in full, or (ii) be limited to the minimum extent necessary to ensure that no portion thereof will fail to be tax-deductible to the Company by reason of Section 280G of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state or local income and employment taxes and the excise tax imposed under Section 4999 of the Code, results in the receipt by Executive, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be subject to the excise tax imposed under Section 4999 of the Code. In the event that the payments and/or benefits are to be reduced pursuant to this Section 14, such payments and benefits shall be reduced such that the reduction of cash compensation to be provided to Executive as a result of this Section 14 is minimized. Notwithstanding the immediately preceding sentence, in applying this principle, the reduction shall be made in a manner consistent with the requirements of Section 409A of the Code, and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis but not below zero. All determinations required to be made under this Section 14 shall be made by the Company’s independent public accounting firm or by another advisor mutually agreed to by the parties.

16.    Indemnification. Company shall indemnify and defend Executive against all claims arising out of Executive’s activities as an officer or employee of Company or its affiliates to the fullest extent permitted by law and under Company’s organizational documents, except that the Company shall not indemnify and defend Executive against any claims brought against Executive by the Company, Enstar, or any of their affiliates. During Executive’s employment and for six (6) years following the end of Executive’s employment, Executive shall be entitled to be covered by a policy of directors’ and officers’ liability insurance on commercially reasonable terms sufficient to cover the risk to Executive that would reasonably be expected to result from his activities as an officer or employee of the Company or its affiliates as aforesaid and a copy of the policy shall be provided to Executive upon his request from time to time. At the request of the Company, Executive shall, during and after Executive’s employment with the Company, render reasonable assistance to the Company in connection with any litigation or other proceeding involving the Company or any of its affiliates, unless precluded from so doing by law. The Company shall provide reasonable compensation to Executive for such assistance rendered after Executive’s employment ceases and will reimburse Executive for reasonable attorneys’ fees incurred as a result of Executive’s requested assistance pursuant to this Section.

17.    Clawback Right. Notwithstanding any other provisions in this Agreement to the contrary, any incentive-based compensation paid to Executive pursuant to this Agreement or any other agreement or arrangement with the Company or Enstar that is subject to recovery under any law, government regulation, stock exchange listing requirement, or Enstar policy approved by the Enstar or Company board and notified to Executive, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation, stock exchange listing requirement, or Enstar policy.

18.    General Provisions.

(a)    Entire Agreement. This Agreement (inclusive of the Confidentiality Agreement) is the entire and final agreement and understanding of the parties relating to the subject matter hereof and shall supersede all prior or other current negotiations, agreements, representations, warranties, and understandings, whether written or oral, between the parties or any subsidiaries or other affiliates of a party, including, but not limited to, the Original Agreement.

(b)    Assignment; Binding Effect. This Agreement is a personal services contract, and neither this Agreement nor any rights or obligations hereunder may be assigned or transferred or delegated or otherwise disposed of by Executive without the prior written consent of the Company, which may be withheld in its sole discretion, and any purported assignment or transfer or delegation or other disposition by Executive without such consent shall be null and void. Executive acknowledges and

10

agrees that the Company has the right and power to assign or transfer or delegate or otherwise dispose of this Agreement or any rights or obligations hereunder in its sole discretion and in whole or in part, whether by merger, consolidation, reorganization, sale or other transfer or disposition of assets or stock or operation of law or otherwise, and specifically including to any other member or affiliate of Enstar. Subject to the foregoing restrictions on Executive, this Agreement shall inure to the benefit of and be binding upon each of the parties; the affiliates, officers, directors, agents, successors and assigns of the Company; and the heirs, devisees, spouses, legal representatives, successors and permitted assigns of Executive. Other than Enstar, which is a third-party beneficiary of this Agreement, there are no intended third-party beneficiaries under this Agreement.

(c)    Amendments, Waivers. This Agreement or any provision hereof may not be amended except by a writing signed by Executive and by a duly authorized representative of the Company other than Executive. Any waiver of any provision of this Agreement must be in writing and executed by the party waiving such provision. The waiver of a party of any default or breach of this Agreement shall not constitute a waiver of any other or subsequent default or breach. The Company shall not be required to give notice to enforce strict adherence to all terms of this Agreement.

(d)    Severability. If any provision of this Agreement shall be held by a court or arbitrator of competent jurisdiction to be invalid or unenforceable or void, such provision shall be enforced to the fullest extent not prohibited by law and shall be revised to the extent necessary to make such provision a valid and enforceable and legal provision consistent with the original intent and/or economic effect of such provision, and the remaining provisions hereof will remain in full force and effect. In addition, if any one or more provisions contained in this Agreement shall be held to be excessively broad as to duration, geographical scope, activity or subject, such provision shall be construed by limiting or reducing it, so as to be enforceable under applicable law, and the parties agree that any presiding court or arbitrator shall be requested to do so.

(e)    Governing Law. This Agreement and all matters arising out of or relating to or in connection with this Agreement shall be governed by and construed in accordance with the laws of the State of New York, without application of conflict of law rules, subject to the application of the Federal Arbitration Act.

(f)    Notices. Any notice, request, demand, or other communication required or permitted hereunder shall be in writing, shall reference this Agreement, and shall be deemed to be properly given: (i) when delivered personally, by courier, or by e-mail or (ii) five (5) business days after having been sent by registered or certified mail, return receipt requested, postage prepaid. All notices shall be sent to the respective addresses set forth in the signature page of this Agreement. Any party may change its notice address or e-mail address by notifying the other party of such change in compliance with this Section.

(g)    Representations. Each party represents and warrants that such party has the full right, power and authority to enter into, execute and deliver this Agreement and to perform its or his obligations hereunder, and that this Agreement shall constitute its or his valid and legally binding agreement enforceable in accordance with its terms.

(h)    Remedies Cumulative. The remedies provided in this Agreement shall be cumulative and shall not preclude any party from asserting any other right, or seeking any other remedies, against the other party.

(i)    Interpretation. When the context requires, the plural shall include the singular and the singular the plural; and any gender reference shall include any other gender or the absence of gender. All references to “including” or “includes” or any variation thereof shall be deemed to include the terms “without limitation”. The words “hereunder,” “hereof,” “hereto” and words of similar import shall be deemed references to this Agreement as a whole. To the extent not prohibited by law, this Agreement

11

shall not be construed against the drafter. Section headings are not part of this Agreement and are only for the convenience of the parties.

(j)    Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. Facsimile or PDF signatures shall be deemed as effective as originals.

(k)    Executive Acknowledgment. Executive hereby acknowledges that he has had the opportunity to and did consult legal counsel concerning this Agreement, that he has read and understands the agreement, that he is fully aware of its legal effect, and that he has entered into the agreement freely and based on his own judgment and not on any representations or promises other than those expressly provided in this agreement.

Exhibit 10.2

Amendment No. 2

to

Employment Agreement

This Amendment No. 2 (this “Amendment”) is entered into on April 4, 2024 (the “Signing Date”) and is effective as of January 12, 2024 (the “Effective Date”), between Enstar (US) Inc., a Delaware corporation (“Company”) and Paul Brockman (“Executive”) and amends the Employment Agreement between Company and Executive entered into January 8, 2018, as amended March 21, 2023 (the “Current Employment Agreement”).

BACKGROUND

WHEREAS, Company and Executive have agreed to certain changes to his role and responsibilities and wish to amend the Current Employment to reflect such changes;

WHEREAS, Executive’s title in the Current Employment Agreement is “Chief Operating Officer and Chief Claims Officer of Enstar Group”;

WHEREAS, Executive will continue to serve as “Chief Operating Officer of Enstar Group,” but:

i)    Effective as of January 12, 2024, Executive assumes the additional role of Interim Chief Executive Officer for Enstar (EU) Limited, for an undetermined interim period (capped at roughly two calendar years), to provide direction and oversight in connection with the transition from the retiring current CEO, and this appointment has been approved by the Enstar (EU) Limited board of directors; and

ii)    Effective as of January 29, 2024, Executive consents to the relinquishment of his Chief Claims Officer title and role, because Company, with Executive’s support, has hired a new Chief Claims Officer reporting into Executive.

WHEREAS, Company and Executive agree to make such other changes as are necessary to reflect the change in circumstances and the parties’ intent.

NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein and intending to be legally bound hereby, the parties hereto agree as follows:

AMENDED TERMS

1.    Position and Duties. Section 2(a) of the Current Employment Agreement is hereby amended and restated as follows:

(a)    Position and Duties.

(i)    During the Employment Period, Executive shall serve as Chief Operating Officer of Enstar Group, with such duties, authority and responsibilities as are commensurate with such position and assigned by the Company and Enstar Group Limited.During the Employment Period, Executive shall faithfully perform all of the duties and responsibilities for the position and shall devote his best efforts and full time and attention to the business of Enstar (except for vacation periods and reasonable periods of absence for illness or incapacity as not prohibited by the Company’s general employment policies and the terms of this Agreement). Executive shall directly report to the Enstar Group Limited Chief Executive Officer, who shall have authority to change such reporting line in his discretion. The Executive will be based in the Company’s offices in St. Petersburg,

Florida, although it is understood that Executive may be required to visit other offices and locations from time to time and that Executive’s position will require travel. Notwithstanding the foregoing, Executive may devote reasonable time to personal and professional activities, including without limitation participation in committees, professional associations, and board memberships, in each case so long as such activities are in accordance with the Code of Conduct and approved in writing by Enstar Group Limited's Chief Executive Officer.

(ii)    During an interim period intended to last until a successor is identified, Executive shall also serve as Interim Chief Executive Officer of Enstar (EU) Limited, the U.K.-based service company that is a subsidiary of Enstar Group Limited and sister entity of Company. In such role, Executive shall also report to the Enstar (EU) Limited board of directors. Executive’s UK role shall be subject to that certain Contract of Employment between Enstar (EU) Limited and Executive, effective as of the Effective Date (the “UK Contract”). Company consents to this arrangement and acknowledges Executive will spend approximately 50% of his full-time working hours performing Interim Chief Executive Officer of Enstar (EU) Limited services.

(iii)    At such time as Enstar Group determines his interim services in the UK role under the UK Contract are no longer necessary (for example, if a successor is named), Executive shall submit all appropriate resignations and consent to transitioning and relinquishing suc officer and and any related director roles. For the avoidance of doubt, such a change shall not constitute an actual or constructive termination of employment or notice of termination of employment, nor shall it trigger Severance Payments or severance benefits of any kind. At such time, Executive is expected to return to spending 100% of his full-time working hours performing Group Chief Operating Officer services for Company.

2.    Base Salary. Section 2(b)(i) of the Current Employment Agreement shall be amended and restated in its entirety as follows:

During the Employment Period, Executive shall receive a base salary (“U.S.Base Salary”), initially with effect from the Effective Date, at an annualized rate equal to the following formula: (A) Eight hundred thousand dollars ($800,000) (“Global Base Salary”) minus(B) “Salary” as defined in the UK Contract in effect from time to time, payable in accordance with the Company’s standard payroll practices and subject to statutory payroll deductions and withholdings. Executive acknowledges that he is an exempt employee and, accordingly, that he is not entitled to overtime pay regardless of the number of hours required to complete his duties hereunder. The Global Base Salary of Executive will be reviewed from time to time in accordance with the established procedures of the Company for adjusting salaries for similarly situated employees and may be increased in the sole discretion of the Company. The Company’s annual salary review is conducted on April 1 of each year. Executive will first be eligible for a merit increase on April 1st, 2025.

3.    Performance Bonus Plan. Section 2(b)(ii)(A) and (B) of the Current Employment Agreement shall be amended and restated in its entirety as follows:

A)    For the performance year period beginning on January 1, 2024, Executive was selected as one of the Enstar employees whose performance bonus is governed by the group executive team program, which specifies performance bonus opportunity subject to achievement of the Enstar financial and corporate performance metrics and individual operational objectives adopted by Enstar’s Compensation Committee in its sole discretion from time to time. As part of this program,

2

Enstar’s Compensation Committee has established Executive’s “threshold,” “target,” and “maximum” 2024 performance bonus opportunity as 75%, 125%, and 150% of U.S. Base Salary, respectively, with actual performance bonus payments subject to a 10% adjustment amount (increase or decrease). The program’s nature and structure are subject to review and discretion of Enstar’s Compensation Committee on an annual basis and is therefore subject to change upon their approval from time to time.

(B)    For performance year periods beginning on January 1, 2025, Executive shall, following the completion of each fiscal year, be eligible for a performance bonus in accordance with Enstar’s bonus program, as administered by Enstar’s Compensation Committee at a level commensurate with his position and in accordance with the policies and practices of Enstar.

4.    Equity Incentives. Section 2(b)(iii)(A) of the Current Employment Agreement shall be amended and restated in its entirety as follows:

(A)    Commencing in 2024 and during the Employment Period, Executive shall be eligible to continue to participate in the Enstar long-term incentive program in effect from time to time at a level commensurate with his position and in accordance with the policies and practices of Enstar. The long-term incentive program is administered by the Enstar Compensation Committee and subject to its discretionary review and approval each year, and therefore Enstar can only provide guidance that it expects Executive’s eligibility for future awards to be based on one-hundred thirty-five percent (135%) of Global Base Salary annually, with the awards expected to be comprised of a combination of Restricted Stock Units (“RSUs”) pursuant to the terms and conditions of Enstar’s Amended and Restated 2016 Equity Incentive Plan (or any successor plan) (the “Equity Incentive Plan”) and approved forms of RSU award agreements, and Performance Stock Units (“PSUs”) pursuant to the terms and conditions of the Equity Incentive Plan and approved forms of PSU award agreements, in the proportion established by the Enstar Compensation Committee (which proportion is currently thirty percent (30%) RSUs and seventy percent (70%) PSUs, but is subject to change from time to time).

5.    Paid Time Off. For so long as Executive is employed by Enstar (EU) Limited, his PTO under the Current Employment Agreement shall be reduced to fifteen (15) business days, with the parties’ intention being that he will be entitled to thirty (30) PTO days per year in the aggregate between his Current Employment Agreement and the UK Contract.

6.    Termination without Cause by the Company. Section 5(b) of the Current Employment Agreement shall be amended and restated in its entirety as follows:

The Company may unilaterally terminate the employment of Executive at any time without Cause, as defined in Section 7, upon thirty (30) days advance written notice. If Executive’s employment is terminated by the Company without Cause, then upon Executive’s signing (and non-revocation) of a separation agreement containing a plenary release of claims in a form acceptable to the Company (a “Release”), Executive shall be entitled to receive, in addition to all earned compensation through his Termination Date: (i) salary continuation at his then-current Global Base Salary for the greater of (A) twelve (12) months after the Termination Date or (B) the number of pay periods required by the Company’s Severance Pay Plan and (ii) if, for the year in which Executive’s employment is terminated pursuant to this Section, the Company achieves the performance goals established in accordance with any incentive plan in which he participates, including for this purpose, any incentive plan in which he participates with respect to his employment by Enstar (EU) Limited, the Company shall pay Executive an amount equal to the bonus that he would have received had he been employed by the Company for the full year, multiplied by a fraction, the numerator of which is the number of calendar days Executive was employed in such year and the denominator of which is 365 (the “Severance Payments”).

3

Notwithstanding the foregoing, all Severance Payments not yet paid by March 15 of the calendar year following the Termination Date shall be paid in a lump sum on such March 15 or the first business day prior thereto. In addition, upon termination of Executive’s employment pursuant to this Section, any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder.

7.    Termination by Disability. Section 7(c) of the Current Employment Agreement shall be amended and restated in its entirety as follows:

By Disability. If Executive becomes eligible for the long term disability benefits of the Company or if, in the reasonable opinion of the Board of Directors of the Company, Executive is unable to carry out the responsibilities and functions of the position held by Executive by reason of any physical or mental impairment for more than ninety (90) consecutive days or more than one hundred and twenty (120) days in any twelve (12) month period, then, to the extent not prohibited by law, the Company may terminate Executive’s employment. The Company shall pay to Executive (i) all compensation to which Executive is entitled up through the Termination Date, (ii) salary continuation at Executive’s then-current U.S Base Salary for six (6) months after the Termination Date minus any disability payments received by Executive from disability insurance policies paid for by the Company, and (iii) if, for the year in which Executive’s employment is terminated pursuant to this Section, the Company achieves the performance goals established in accordance with any incentive plan in which he participates, including for this purpose, any incentive plan in which he participates with respect to his employment by Enstar (EU) Limited, the Company shall pay Executive an amount equal to the bonus that he would have received had he been employed by the Company for the full year, multiplied by a fraction, the numerator of which is the number of calendar days Executive was employed in such year and the denominator of which is 365 (the “Disability Payments”). Notwithstanding the foregoing, all Disability Payments not yet paid by March 15 of the calendar year following the Termination Date shall be paid in a lump sum on such March 15 or the first business day prior thereto]. In addition, upon termination of Executive’s employment pursuant to this Section, any and all RSUs and PSUs awarded to Executive prior to the Termination Date shall be treated pursuant to the terms of the Equity Incentive Plan and the applicable award agreements thereunder. Thereafter all obligations of the Company under this Agreement shall cease. Nothing in this Section shall affect Executive’s rights under any disability plan or other applicable benefit plans or policies in which Executive is a participant. For clarity, Executive shall not be entitled to Severance Benefits in the event of a termination pursuant to this Section.

8.    Non-solicitation. Section 10 of the Current Employment Agreement shall be amended and restated in its entirety as follows:

Non-Solicitation. During the term of his employment with the Company and for a period of six (6) months immediately after the date his employment terminates for any reason, Executive agrees that Executive will not, directly or indirectly, (i) call upon, solicit, divert, or take away any of the clients, business, or business partners of Enstar, or request or cause any of the above to abandon, cancel or terminate any part of their relationship with Enstar, or (ii) solicit, entice, or attempt to persuade any employee, agent, consultant, or independent contractor of Enstar to leave the service of Enstar for any reason or take any other action that may cause any such individual to terminate his relationship with Enstar.

9.    No Other Changes to Compensation. Except as expressly provided herein, there shall be no other changes to Executive’s compensation and benefits under the Current Employment Agreement, which shall remain in full force and effect. The parties acknowledge that Executive’s employment with Enstar (EU) Limited is independent from his employment with the Company, but their mutual intention is that neither party is financially better or worse off as a result of the split employment arrangement relative

4

to the Executive’s previous employment relationship solely with the Company, except that Enstar (EU) Limited has agreed to make certain tax equalization payments designed to ensure that the Executive’s tax burden is not increased as a result of the split employment arrangement. Except as expressly set forth herein, the terms of the Current Employment Agreement shall be unaffected by the UK Contract and if there is any inconsistency between any of the provisions of the Current Employment Agreement as amended hereby and the UK Contract, the Current Employment Agreement as amended hereby shall prevail.

10.    Counterparts. This Amendment may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. Facsimile or PDF signatures shall be deemed as effective as originals.

1.2    Your employment is at all times conditional on you providing satisfactory evidence that you have the legal right to work in the UK and you will notify the Company immediately if this changes.

9.3    You must notify your Line Manager by 9.30am on the first day of absence of any illness, accident or other incapacity and thereafter at such intervals as the Company may require.

If you are not able to return to work within seven consecutive calendar days you must obtain a certificate from a doctor, at weekly or prescribed intervals so long as the absence continues. The certificate(s) must be forwarded to your Line Manager without delay. You should enclose a note on your recovery or progress when forwarding medical evidence. Payment of SSP and any Company sick pay is subject to your continued compliance with these conditions.

9.4    If required to by the Company during any period of sickness absence, you agree to submit yourself (at the Company’s expense) to medical examination by a medical practitioner nominated by the Company and to authorise such practitioner in writing to disclose and discuss with the Company the results.

10.    Inventions and Intellectual Property

10.1    You acknowledge that any Employment IPR and all materials embodying them shall automatically belong to the Company to the fullest extent permitted by law. To the extent that they do not vest in the Company automatically, you hold them on trust for the Company.

10.2    You irrevocably and unconditionally waive to the fullest extent permitted by law all moral rights to which you may be entitled under the Copyright Designs and Patents Act 1988, and all similar rights in other jurisdictions relating to any copyright which forms all or part of any Employment IPR, created by you and belonging to the Company. You agree not to support, maintain or permit any claim for infringement of moral rights in such copyright works. You confirm and acknowledge that this waiver will operate in favour of the Company, its licensees, assigns and successors in title.

10.3    You undertake to execute all documents and do all acts both during and after your employment by the Company as may, in the opinion of the Company, be necessary or desirable to vest the Employment IPR in the Company, to register them in the name of the Company and to protect and maintain the Employment IPR. The Company agrees to reimburse your reasonable expenses in complying with this clause.

11.    Confidentiality

11.1    You will not, whether during or after the termination of your employment, except in the proper course of your duties or as required by law:

Accounting Policies [Abstract]

BASIS OF PRESENTATION

1. BASIS OF PRESENTATION

Enstar Group Limited ("Enstar") is a leading global (re)insurance group that offers innovative capital release solutions through its network of group companies in Bermuda, the United States, the United Kingdom, Continental Europe and Australia. Our core focus is acquiring and managing (re)insurance companies and portfolios of (re)insurance business in run-off.

These unaudited condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the financial information and note disclosures required by U.S. GAAP for complete consolidated financial statements.

In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for a fair statement of the financial results for the interim periods. All intercompany accounts and transactions have been eliminated and certain comparative information has been reclassified to conform to the current presentation.

The results of operations for any interim period are not necessarily indicative of results for the full year. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2023.

Recently Issued Accounting Pronouncements Not Yet Adopted

ASU 2023-07 - Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, which includes the following amendments to Topic 280 Segment Reporting:

•Disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the segment measure of profit or loss;

•Disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition;

•Disclose, on an interim basis, all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280;

•Clarify that an entity is not precluded from reporting one or more additional measure(s) of segment profit or loss if the CODM uses more than one measure in assessing segment performance and deciding how to allocate resources;

•Disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources; and

•Require an entity with a single reportable segment to provide all disclosures required by the amendments in ASU 2023-07 and all existing segment disclosures in Topic 280.

These amendments are effective for annual reporting periods beginning after December 15, 2023 and interim reporting periods beginning after December 15, 2024, and must be applied retrospectively to all prior periods presented. Early adoption is permitted.

Adopting ASU 2023-07 will require us to expand our segment disclosures. We are currently determining the period in which the new guidance will be adopted.

ASU 2023-09 - Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, which includes the following amendments to Topic 740 Income Taxes:

•Disclose, on an annual basis, specific categories in the rate reconciliation;

•Disclose, on an annual basis, additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate);

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes;

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received);

•Disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign;

•Disclose income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign;

•Eliminates the requirement to disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or make a statement that an estimate of the range cannot be made; and

•Eliminates the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures.

These amendments are effective for annual reporting periods beginning after December 15, 2024, and should be applied prospectively, however retrospective application is permitted. Early adoption is permitted.

Adopting ASU 2023-09 will require us to expand our income tax disclosures. We are currently determining the period in which the new guidance will be adopted.

Segment Reporting [Abstract]

SEGMENT INFORMATION

2. SEGMENT INFORMATION

Our segment structure is aligned with how our CODM, our Chief Executive Officer, views our business, assesses performance and allocates resources to our business components. Effective January 1, 2024, our business is organized into two reportable segments: (i) Run-off and (ii) Investments. In addition, our Corporate and other activities, which do not qualify as an operating segment, include income and expense items that are not directly attributable to our reportable segments and activities from the former Assumed Life and Legacy Underwriting reportable segments.

Effective January 1, 2024, each of our Assumed Life and Legacy Underwriting reportable segments were determined to no longer meet the definition of reportable segments as they no longer engage in any active business activities following the series of commutation and novation transactions in Enhanzed Re and the settlement of the arrangements between SGL No. 1, Arden, and Atrium. Given the cessation of business activities and that all remaining activities are not expected to be material, all residual income or expense of the former Assumed Life and Legacy Underwriting reportable segments will be prospectively included within our Corporate and other activities.

The Assumed Life segment previously included Enhanzed Re’s life and property aggregate excess of loss (catastrophe) business. In August 2022, Enhanzed Re entered into a Master Agreement with Cavello Bay Reinsurance Limited (“Cavello”), a wholly-owned subsidiary of Enstar, and Allianz, pursuant to which a series of commutation and novation agreements were completed which ceased any continuing reinsurance obligations for this segment. We recognized the impact of transactions that closed in the fourth quarter of 2022 in the first quarter of 2023 due to the quarter lag in reporting.

The Legacy Underwriting segment previously included participation in direct underwriting activities, including a 25% participation within 2020 and prior underwriting years of Atrium's Syndicate 609 at Lloyd's, offset by the contractual transfer of the results of that business to the Atrium entities that were divested in an exchange transaction. All remaining contractual arrangements were settled in the second quarter of 2023. Other than the settlement of these amounts, no other transactions were recorded in the Legacy Underwriting segment in 2023.

Our assets are reviewed on a consolidated basis by management for decision making purposes since they support business operations across both of our reportable segments as well as our Corporate and other activities. We do not allocate assets to our reportable segments with the exception of (re)insurance balances recoverable on paid and unpaid losses and goodwill (all goodwill is attributable to the Run-off segment) that are directly attributable to our reportable segments.

The following table sets forth select unaudited condensed consolidated statements of operations results by segment and our Corporate and other activities:

(1) Effective January 1, 2024, Assumed Life and Legacy Underwriting were determined to no longer meet the definition of reportable segments and their residual income and loss activities were prospectively included in Corporate and other activities. Activities prior to January 1, 2024 are recorded in their respective segments. In addition, Legacy Underwriting had no revenue or income activity for the three months ended March 31, 2024 and 2023 and therefore is excluded from the table above.

(2) Other expense for Corporate and other activities includes the amortization of fair value adjustments associated with the acquisition of DCo and Morse TEC.

(3) Net incurred losses and LAE for Corporate and other activities includes fair value adjustments associated with the acquisition of companies and the changes in the discount rate and risk margin components of the fair value of assets and liabilities related to our assumed retroactive reinsurance contracts for which we have elected the fair value option.

As of March 31, 2024 and December 31, 2023, the number of securities classified as AFS in an unrealized loss position for which an allowance for credit loss is not recorded was 2,363 and 2,156, respectively. Of these securities, the number of securities that had been in an unrealized loss position for twelve months or longer was 1,549 and 1,736, respectively.

The contractual terms of a majority of these investments do not permit the issuers to settle the securities at a price less than the amortized cost basis of the security. While interest rates have increased and credit spreads have widened, and in certain cases credit ratings were downgraded, we currently do not expect the issuers of these fixed maturities to settle them at a price less than their amortized cost basis and therefore it is expected that we will recover the entire amortized cost basis of each security. Furthermore, we do not intend to sell the securities that are currently in an unrealized loss position, and it is also not more likely than not that we will be required to sell the securities before the recovery of their amortized cost bases.

(1) As of March 31, 2024, we own 24.6% of the common shares in Monument Re. We converted all of our preferred shares in Monument Midco to common shares in Monument Re on January 2, 2024. As of December 31, 2023, we owned 20.0% of the common shares in Monument Re as well as preferred shares in Monument Midco which had fixed dividend yields (where declared). Losses for the three months ended March 31, 2024 include an other-than-temporary impairment charge.

Funds Held

Under funds held arrangements, the reinsured company has retained funds that would otherwise have been remitted to us. The funds held balance is credited with investment income and losses paid are deducted.

We present funds held as a single category within the consolidated balance sheets. The following table summarizes the components of funds held:

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Funds held - directly managed	$	2,336	$	2,502
Funds held by reinsured companies	2,544		2,749
Total funds held	$	4,880	$	5,251

Funds Held - Directly Managed

The following table summarizes the components of the investments collateralizing the funds held - directly managed:

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Funds held - directly managed, at cost	$	2,450	$	2,608
Fair value changes in:
Accumulated change in fair value - embedded derivative accounting	(114)		(106)
Funds held - directly managed, at fair value	$	2,336	$	2,502

The majority of our funds held - directly managed is comprised of short-term and fixed maturities. The $166 million decrease in funds held - directly managed from December 31, 2023 to March 31, 2024 was primarily driven by net paid losses.

Funds Held by Reinsured Companies

The following table summarizes the components of our funds held by reinsured companies:

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Funds held by reinsurance companies, at amortized cost	$	2,522	$	2,709
Fair value of embedded derivative (1)	22		40
Funds held by reinsured companies	$	2,544	$	2,749

(1) Pursuant to the terms of the Aspen Insurance Holdings transaction entered in 2022, in addition to earning a fixed crediting rate (“base crediting rate”) on the funds withheld through September 30, 2025, we receive a variable return (together, the “full crediting rate”). The embedded derivative represents the fair value of the amount by which all future interest payments on the funds withheld balance made at the full crediting rate are expected to exceed all future interest payments made on the funds withheld balance at the base crediting rate.

The $205 million decrease in funds held by reinsured companies from December 31, 2023 to March 31, 2024 was primarily driven by net paid losses specific to the Aspen LPT.

The gross realized gains and losses on AFS investments for the three months ended March 31, 2024 and 2023 included in the table above resulted from sales of AFS investments of $436 million and $656 million, respectively.

For the three months ended March 31, 2024 and 2023, fair value changes in trading securities, funds held and other investments recorded within the statement of operations relating to equity securities still held on the balance sheet date were $37 million and $43 million, respectively.

Restricted Assets

The carrying value of our restricted assets, including restricted cash of $310 million and $266 million, as of March 31, 2024 and December 31, 2023, respectively, was as follows: 

	March 31, 2024		December 31, 2023
	(in millions of U.S. dollars)
Collateral in trust for third party agreements	$	4,901	$	5,301

Collateral for secured letter of credit facilities	74		78
Funds at Lloyd's (1)	272		389
	$	5,327	$	5,848

(1) We managed and provided capacity for one Lloyd's syndicate as of both March 31, 2024 and December 31, 2023. Lloyd's determines the required capital principally through the use of an internal model that calculates a solvency capital requirement for each syndicate. This capital is referred to as FAL and will be drawn upon in the event that a syndicate has a loss that cannot be funded from other sources.

Derivatives and Hedging Instruments

3 Months Ended

Mar. 31, 2024

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES AND HEDGING INSTRUMENTS

4. DERIVATIVES AND HEDGING INSTRUMENTS

Accounting for Derivatives

Freestanding Derivatives

Freestanding derivatives are recorded on trade-dates and carried on the consolidated balance sheet either as assets within other assets or as liabilities within other liabilities at estimated fair value. We do not offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting agreement.

If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are reported in fair value changes in trading securities, funds held and other investments included in our consolidated statements of operations.

Hedge Accounting

To qualify for hedge accounting, at the inception of the hedging relationship, we formally document the risk management objective and strategy for undertaking the hedging transaction, as well as the designation of the hedge.

We have qualifying net investment in foreign operation (“NIFO”) hedges. We recognize changes in the estimated fair value of the hedging derivatives within OCI, consistent with the translation adjustment for the hedged net investment in the foreign operation.

Our documentation sets forth how the hedging instrument is expected to hedge the designated risks related to the hedged item and also sets forth the method that will be used to retrospectively and prospectively assess the hedging instrument’s effectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk of the hedged item. Hedge effectiveness is formally assessed at inception and at least quarterly throughout the life of the designated hedging relationship. Assessments of hedge effectiveness are also subject to interpretation and estimation and different interpretations or estimates may have a material effect on the amount reported in net income.

When hedge accounting is discontinued pursuant to a NIFO hedge (due to a revaluation, payment of a dividend or the disposal of our investment in a foreign operation), the derivative continues to be carried on the balance sheet at its estimated fair value. Deferred gains and losses recorded in OCI pursuant to a discontinued NIFO hedge are recognized immediately in net foreign exchange losses (gains) in our consolidated statements of operations.

Embedded Derivatives

We are party to certain reinsurance agreements that have embedded derivatives. We also have embedded derivatives on our convertible bond portfolio, recorded within fixed maturities, trading on the consolidated balance sheets. We assess each identified embedded derivative to determine whether it is required to be bifurcated. The embedded derivative is bifurcated from the host contract and accounted for as a freestanding derivative if:

•the combined instrument is not accounted for in its entirety at estimated fair value with changes in estimated fair value recorded in net income;

•the terms of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract; and

•a separate instrument with the same terms as the embedded derivative would qualify as a derivative instrument.

Such embedded derivatives are carried on the consolidated balance sheet at estimated fair value with the host contract and changes in their estimated fair value are generally reported within fair value changes in trading securities, funds held and other investments.

Derivative Strategies

We are exposed to various risks relating to our ongoing business operations, including interest rate, foreign currency exchange rate, credit and equity price risks. We use a variety of strategies to manage these risks, including the use of derivatives.

Derivatives are financial instruments with values derived from interest rates, foreign currency exchange rates, credit spreads and/or other financial indices. The types of derivatives we use include swaps and forwards.

Foreign Currency Derivatives

We use foreign currency exchange rate derivatives, including foreign currency forwards, to reduce the risk from fluctuations in foreign currency exchange rates associated with our assets and liabilities denominated in foreign currencies. We also use foreign currency derivatives to hedge the foreign currency exchange rate risk associated with certain of our net investments in foreign operations.

In a foreign currency forward transaction, we agree with another party to deliver a specified amount of an identified currency at a specified future date. The price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. We utilize foreign currency forwards in fair value, NIFO hedges and nonqualifying hedging relationships.

Interest Rate Derivatives

We use interest rate derivatives, specifically interest rate swaps, to reduce our exposure to changes in interest rates.

Interest rate swaps are used by us primarily to reduce market risks from changes in interest rates and to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches). In an interest rate swap, we agree with another party to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts as calculated by reference to an agreed notional amount. We utilize interest rate swaps in nonqualifying hedging relationships.

In February 2023, we entered into a two-month forward interest rate swap, receiving a fixed rate and paying a floating rate with a notional value of $800 million to partially mitigate the risk that interest rates could decrease prior to our receipt of the cash consideration for the QBE LPT transaction. Following the expiration of the forward period in April 2023, we took delivery of a three-year receive fixed, pay floating interest rate swap. The notional value of the swap was subsequently partially unwound as the consideration received was invested. The swap was fully unwound in July 2023. As of March 31, 2024 and December 31, 2023, we had no interest rate swaps.

The following table presents the gross notional amounts and estimated fair values of our derivatives recorded within other assets and other liabilities on the consolidated balance sheets as of March 31, 2024 and December 31, 2023:

Deferred Charge Assets and Deferred Gain Liabilities

3 Months Ended

Insurance [Abstract]

DEFERRED CHARGE ASSETS AND DEFERRED GAIN LIABILITIES

5. DEFERRED CHARGE ASSETS AND DEFERRED GAIN LIABILITIES

If, at the inception of a retroactive reinsurance contract, the estimated liabilities for losses and LAE exceed the consideration received, a deferred charge asset (“DCA”) is recorded for this difference. In contrast, if the consideration received is in excess of the estimated undiscounted ultimate losses payable, a deferred gain liability (“DGL”) is recorded.

We amortize the net DCA balances over the estimated claim payment period of the related contracts with the amortization prospectively adjusted at each reporting period to reflect new estimates of the pattern and timing of remaining losses and LAE payments.

The following table presents a summary of the DCA balances and related activity for the three months ended March 31, 2024 and 2023 (there were no DGL balances in either period):

	Three Months Ended March 31,
	2024		2023

Amortization	(30)		(17)
Ending carrying value	$	701	$	641

For each of the three months ended March 31, 2024 and 2023, we completed our assessment for impairment of deferred charge assets and concluded that there had been no impairment of our carried deferred charge asset balances.

Losses and Loss Adjustment Expenses

Insurance [Abstract]

LOSSES AND LOSS ADJUSTMENT EXPENSES

6. LOSSES AND LOSS ADJUSTMENT EXPENSES

The liability for losses and LAE, also referred to as loss reserves, represents our gross estimates before reinsurance for unpaid reported losses (Outstanding Loss Reserves, or "OLR") and includes losses that have been incurred but not yet reported ("IBNR") using a variety of actuarial methods. We recognize an asset for the portion of the liability that we expect to recover from reinsurers. LAE reserves include allocated LAE ("ALAE") and unallocated LAE ("ULAE"). ALAE are linked to the settlement of an individual claim or loss, whereas ULAE are based on our estimates of future costs to administer the claims. IBNR includes amounts for unreported claims, development on known claims and reopened claims.

Our loss reserves cover multiple lines of business, including asbestos, environmental, general casualty, workers' compensation, marine, aviation and transit, construction defect, professional indemnity/directors and officers, motor, property and other non-life lines of business. We complete most of our annual loss reserve studies in the fourth quarter of each year and, as a result, tend to record the largest movements, both favorable and adverse, to net incurred losses and LAE in this period.

We have elected to apply the fair value option for certain reinsurance contracts including, loss portfolio transfers ("LPTs") and reinsurance to close ("RITC") transactions. This is an irrevocable election that applies to all balances under the reinsurance contract, including reinsurance balances recoverable on paid and unpaid losses and the liability for losses and LAE. The primary reason for electing the fair value option was to reduce the earnings volatility created by carrying the liabilities for losses and LAE at cost and the assets supporting those liabilities at fair value. During 2017 and 2018, we elected the fair value option on select new business and classified the supporting portfolio investments as trading securities, whereby all changes in fair value were recorded in the statements of operations. Commencing in 2019, we discontinued electing the fair value option on new business in order to better align with our evolving investment objectives.

The table below provides a consolidated reconciliation of the beginning and ending liability for losses and LAE:

Prior Period Development

Reduction in Estimates of Net Ultimate Losses

The following table summarizes the change in estimates of net ultimate losses related to prior years in our Run-off segment by line of business:

	Three Months Ended
	March 31, 2024		March 31, 2023
	(in millions of U.S. dollars)

All Other	1		(2)
Total	$	(6)	$	(15)

Three Months Ended March 31, 2024:

The prior period reduction in estimates of net ultimate losses of $6 million was driven by favorable development across multiple lines of business. The primary drivers included favorable development on our Professional Indemnity/Directors and Officers line of business of $29 million, driven by favorable claims experience and favorable development on our Asbestos line of business of $24 million resulting from actuarial analysis. These were partially offset by adverse development on our General Casualty line of business of $18 million driven by adverse claims experience and adverse development on our Environmental line of business of $25 million due to results from actuarial reviews in the period.

Three Months Ended March 31, 2023:

The reduction in estimates of net ultimate losses of $15 million related to prior periods was primarily due to the workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Reduction in Provisions for ULAE

Three Months Ended March 31, 2024 and 2023:

The favorable reduction in provisions for ULAE for the three months ended March 31, 2024 and 2023 was driven by ULAE provision adjustments, due to the corresponding reductions in loss reserves and the associated estimated cost of managing such liabilities.

Changes in Fair Value - Fair Value Option

Three Months Ended March 31, 2024 and 2023:

PPD for the three months ended March 31, 2024 was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $4 million, which was primarily driven by an increase in U.K. corporate bond yields during the first quarter of 2024. The corporate bond yields, which form a component of the discount rate used to calculate the fair value of the liabilities, are matched to the original currencies of the underlying loss portfolios, of which GBP is the predominant currency for those portfolios that we have elected to measure at fair value using the fair value option.

PPD for the three months ended March 31, 2023 was adversely impacted by changes in the fair value of liabilities for which we have elected the fair value option of $20 million due to a decline in corporate bond yields.

Insurance [Abstract]

FUTURE POLICYHOLDER BENEFITS

7. FUTURE POLICYHOLDER BENEFITS

The provision for future policyholder benefits includes provisions for life contingent liabilities assumed as well as other policy benefits for insureds. The future policyholder benefits are equal to the present value of the future benefits payments and related expenses less the present value of future net premiums.

The assumed liabilities for future policyholder benefits are comprised primarily of in-payment annuity contract liabilities, which are classified as limited-payment contracts. The balances of and changes in liability for future policyholder benefits is as follows:

	Three Months Ended March 31,
	2023
	(in millions of U.S. dollars)
Beginning Balance	$	821
Benefits paid	(6)
Effect of exchange rate movement	13
Derecognition (1)	(828)
Balance as of March 31	—

(1) In November 2022, we completed a novation of the reinsurance of a closed block of life annuity policies, which was recorded in our first quarter 2023 results due to a one quarter reporting lag. See below for additional information.

There were no gross premiums recognized for the three months ended March 31, 2023.

The effects of actual variances from expected policyholder behavior experience were not material for the three month period ended March 31, 2023.

Novation of Future Policyholder Benefits

In November 2022, Enhanzed Re completed a novation of the reinsurance of a closed block of life annuity policies to Monument Re Limited, a subsidiary of Monument Insurance Group Limited (“Monument Re”). We settled the life liabilities and the related assets at carrying value in return for cash consideration of $94 million as of the closing date and recorded other income of $275 million. This amount consists of a reclassification adjustment of the component of AOCI related to the unlocking of the discount rate assumption from the adoption of ASU 2018-12 into earnings. Our net income attributable to Enstar was reduced by the amount attributable to Allianz’s 24.9% noncontrolling interest in Enhanzed Re at the time of the transaction and our other income recorded was subject to deferral as profits emerge from the underlying novated business, which is generally over the expected settlement period of the life annuity policies, to account for our 20% ownership interest in Monument Re at the time of the transaction.

The following table illustrates the calculation of the gain as of the closing date of the novation:

	(in millions of U.S. dollars)
Calculation of carrying value as of transaction closing:
Funds held - directly managed and other assumed reinsurance recoverables	$	973
Future policyholder benefits (corresponds to derecognition referenced above)	(828)
Other assumed reinsurance liabilities	(12)
Carrying value of net assets	$	133
Calculation of gain on novation (recorded in first quarter 2023):
Cash consideration received	$	94
Less: carrying value of net assets	(133)
Add: reclassification of remeasurement of future policyholder benefits from AOCI and NCI (1)	363
Amount deferred relating to 20% ownership interest in Monument Re (2)	(49)
Gain on novation (3)	275
Net income attributable to noncontrolling interest	(81)
Gain on novation attributable to Enstar (4)	$	194

(1) Comprised of $273 million from AOCI and $90 million from NCI.

(2) Calculated as 20% of the net Enstar transaction gain of $243 million (representing $324 million, consisting of the $39 million loss when comparing cash consideration to carrying value plus the $363 million reclassification benefit, less Allianz’s 24.9% share equal to $81 million).

(3) Recognized in other income in our unaudited condensed consolidated statements of operations.

(4) Recognized in net income in our unaudited condensed consolidated statements of operations.

During the three months ended March 31, 2024, we amortized $1 million into other income relating to the portion of the gain that was deferred to account for our preexisting ownership interest in Monument Re. For the three months ended March 31, 2023 the total gain on novation attributable to Enstar was $194 million. The remaining deferred gain of $47 million as of March 31, 2024 will be amortized over the expected settlement period of the transferred life annuity policies, which is projected to be approximately 50 years, with the majority of benefit payments occurring in the earlier years.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

9. FAIR VALUE MEASUREMENTS

Fair Value Hierarchy

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants. We use a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. The hierarchy is broken down into three levels as follows:

•Level 1 - Valuations based on unadjusted quoted prices in active markets that we have the ability to access for identical assets or liabilities. Valuation adjustments and block discounts are not applied to Level 1 instruments.

•Level 2 - Valuations based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or significant inputs that are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

•Level 3 - Valuations based on unobservable inputs where there is little or no market activity. Unadjusted third party pricing sources or management's assumptions and internal valuation models may be used to determine the fair values.

In addition, certain of our other investments are measured at fair value using net asset value ("NAV") per share (or its equivalent) as a practical expedient and have not been classified within the fair value hierarchy as defined above.

There have been no material changes in our valuation techniques during the period represented by these unaudited condensed consolidated financial statements.

We have categorized our assets and liabilities that are recorded at fair value on a recurring and nonrecurring basis among levels based on the observability of inputs, or at fair value using NAV per share (or its equivalent) as follows:

Level 3 Measurements and Changes in Leveling

Transfers into or out of levels are recorded at their fair values as of the end of the reporting period, consistent with the date of determination of fair value.

Investments

The following table presents a reconciliation of the beginning and ending balances for all investments measured at fair value on a recurring basis using Level 3 inputs:

	Three Months Ended
	March 31, 2024										March 31, 2023
	Fixed maturity investments				Equities				Total		Equities		Total
	Corporate		Asset-backed		Privately-held Equities		Public Equities				Privately-held Equities

(1) Fair value changes in trading securities, funds held and other investments included in our unaudited condensed consolidated statements of operations is equal to the change in fair value changes in trading securities, funds held and other investments relating to assets held at the end of the reporting period.

Fair value changes in trading securities, funds held and other investments related to Level 3 assets in the tables above are included in fair value changes in trading securities, funds held and other investments in our unaudited condensed consolidated statements of operations.

Transfers into Level 3 are primarily attributable to the lack of observable market transactions and price information and the use of unobservable inputs within valuation methodologies.

Funds Held by Reinsured Companies - Embedded Derivative

As described in Note 3, we have an embedded derivative in relation to the Aspen LPT transaction to account for the fair value of the full crediting rate we expect to earn on the funds withheld received as consideration.

The following table presents a reconciliation of the beginning and ending balances for the embedded derivative measured at fair value on a recurring basis using Level 3 inputs:

	Three Months Ended March 31,

Below is a summary of the quantitative information regarding the significant observable and unobservable inputs used in the internal model to determine fair value on a recurring basis:

Valuation Technique		March 31, 2024	December 31, 2023
	Unobservable (U) and Observable (O) Inputs	Weighted Average
Internal model	Corporate bond yield (O)	A Rated	A Rated
Internal model	Credit spread for Instrument-specific credit risk (U)	0.65%	0.65%
Internal model	Risk cost of capital (U)	5.65%	5.60%
Internal model	Weighted average cost of capital (U)	8.75%	8.75%
Internal model	Average payout - liability (U)	8.13 years	8.12 years
Internal model	Average payout - reinsurance balances recoverable on paid and unpaid losses (U)	8.53 years	8.35 years

The fair value of the liability for losses and LAE and reinsurance balances recoverable on paid and unpaid losses may increase or decrease due to changes in the corporate bond rate, the credit spread for non-performance risk, the risk cost of capital, the weighted average cost of capital and the estimated payment pattern.

In addition, the estimate of the capital required to support the liabilities is based upon current industry standards for capital adequacy.

Changes in the fair value due to changes in average payout and corporate bond yields are included in net incurred losses and loss adjustment expenses in our unaudited condensed consolidated statements of earnings. Changes in the fair value due to changes in credit spread for Instrument-specific credit risk are classified to other comprehensive income.

5.50% Junior Subordinated Notes due 2042	494		467
Total Junior Subordinated Notes	$	840	$	808

The fair value of our Senior Notes and our Junior Subordinated Notes was based on observable market pricing from a third party pricing service.

Both the Senior Notes and Junior Subordinated Notes are classified as Level 2.

Insurance Contracts

Disclosure of fair value of amounts relating to insurance contracts is not required, except those for which we elected the fair value option, as described above.

Remaining Financial Assets and Liabilities

Our remaining financial assets and liabilities were generally carried at cost or amortized cost, which due to their short-term nature approximates fair value as of March 31, 2024 and December 31, 2023.

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]

VARIABLE INTEREST ENTITIES

10. VARIABLE INTEREST ENTITIES

We have investments in certain limited partnership funds which are deemed to be variable interest entities ("VIEs"). The activities of these VIEs are generally limited to holding investments and our involvement in these entities is passive in nature. We consolidate all VIEs in which we are considered to be the primary beneficiary.

GCM Fund

In July 2022, we entered into an agreement to become a limited partner of GCM Blue Sails Infrastructure Offshore Opportunities Fund, L.P. (“GCM Fund”), with an initial commitment of $150 million. At that time, we performed an assessment and concluded that as a result of being a limited partner and having no substantive kick-out or participating rights, the GCM Fund is a VIE. We also concluded that we are the primary beneficiary, as our 99.5% economic interest in the GCM Fund is disproportionately greater than our lack of stated power to direct the activities of the GCM Fund that will most significantly impact the GCM Fund’s economic performance. As a result, we have consolidated the results of the GCM Fund. There was no gain or loss recognized on consolidation.

We recognize the results of the GCM Fund on a one quarter lag. As of March 31, 2024, $100 million of the initial commitment has been called. The carrying amounts of the assets and liabilities of the GCM Fund are presented within existing captions on our consolidated balance sheet as of March 31, 2024. Net investment income, changes in the fair value of assets and liabilities of the GCM Fund and management fees are presented within existing captions in the consolidated statements of operations.

We recognized fair value changes in trading securities, funds held and other investments of $1 million for the three months ended March 31, 2024. Such amounts were less than $1 million for the three months ended March 31, 2023.

Our exposure to risk of loss is limited to the amount of our investment, in accordance with the limited partnership agreement. We have not committed to provide any financial support to the general partner of the GCM Fund. In addition, we have not committed to provide any additional financial support to the GCM Fund in excess of previously funded capital commitments and all undistributed profits and income.

The assets of Enstar are not available to the creditors of the GCM Fund.

Nonconsolidated VIEs

The tables below present the fair value of our investments in nonconsolidated VIEs as well as our maximum exposure to loss associated with these VIEs:

NONCONTROLLING INTERESTS

11. NONCONTROLLING INTERESTS

Redeemable Noncontrolling Interests

In December 2023, we entered into a Purchase Agreement with Trident V Funds and Dowling Capital Partners (together, the “RNCI Holders”) to purchase their remaining equity interest in StarStone Specialty Holdings Limited (“SSHL”). Following the completion of the transaction in December 2023, SSHL became a wholly-owned subsidiary and all redeemable non-controlling interests (“RNCI”) within our unaudited condensed consolidated balance sheets were redeemed.

The following is a reconciliation of the beginning and ending carrying amount of the equity attributable to the RNCI in the prior year period (as of December 2023 we no longer held any RNCI):

Balance at beginning of period	$	168
Net income attributable to RNCI	1
Change in unrealized gains on AFS investments attributable to RNCI	1
Balance as of March 31	$	170

Noncontrolling Interests

As of March 31, 2024 and December 31, 2023, we had $114 million and $113 million, respectively, of non-controlling interests (“NCI”) primarily related to external interests in our subsidiaries.

In December 2022, Enhanzed Re repurchased the entire 24.9% ownership interest Allianz held in Enhanzed Re for $175 million. We recorded the impact of reclassifying the carrying value of the NCI acquired to Enstar shareholders’ equity in our first quarter 2023 results, as we report the results of Enhanzed Re on a one quarter reporting lag.

A reconciliation of the beginning and ending carrying amount of the equity attributable to NCI is included in the unaudited condensed consolidated statements of changes in shareholder's equity.

(1) Weighted-average ordinary shares for basic earnings per share includes ordinary shares (voting and non-voting), but excludes ordinary shares held in the Enstar Group Limited Employee Benefit Trust (the "EB Trust") in respect of Joint Share Ownership Plan ("JSOP") awards, which, as a result of us consolidating the EB trust, are classified as treasury shares.

(2) Share-based dilutive securities include restricted shares, restricted share units, directors’ restricted share units and performance share units. Certain share-based compensation awards were excluded from the calculation for the three months ended March 31, 2024 and 2023 because they were anti-dilutive.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

15. COMMITMENTS AND CONTINGENCIES

Concentration of Credit Risk

We are subject to credit risk principally in relation to our:

i.investments, including equity method investments;

ii.cash and cash equivalents and restricted cash and cash equivalents;

iii.assets pledged to ceding companies under reinsurance contracts;

iv.(re)insurance balances recoverable on paid and unpaid losses; and

v.funds held by reinsured companies and funds held - directly managed (together funds held).

As of March 31, 2024, we had funds held concentrations to reinsurance counterparties exceeding 10% of shareholders’ equity of $4.5 billion (December 31, 2023: $4.8 billion) in aggregate. However, we generally have the contractual ability to offset any shortfall in the payment of the funds held balances with amounts owed by us.

We limit the amount of credit exposure to any one counterparty, and none of our counterparty credit exposures, excluding U.S. government and agency instruments and the reinsurance counterparties noted above, exceeded 10% of shareholders’ equity as of March 31, 2024. As of March 31, 2024, our credit exposure to the U.S. government and agency instruments was $848 million (December 31, 2023: $932 million).

Legal Proceedings

We are, from time to time, involved in various legal proceedings in the ordinary course of business, including litigation and arbitration regarding claims. Estimated losses relating to claims arising in the ordinary course of business, including the anticipated outcome of any pending arbitration or litigation, are included in the liability for losses and LAE in our unaudited condensed consolidated balance sheets. In addition to claims litigation, we may be subject to other lawsuits and regulatory actions in the normal course of business, which may involve, among other things, allegations of underwriting errors or omissions, employment claims or regulatory activity. We do not believe that the resolution of any currently pending legal proceedings, either individually or taken as a whole, will have a material effect on our business, results of operations or financial condition. We anticipate that, similar to the rest of the (re)insurance industry, we will continue to be subject to litigation and arbitration proceedings in the ordinary course of business, including litigation generally related to the scope of coverage with respect to A&E and other claims.

Unfunded Investment Commitments

As of March 31, 2024, we had unfunded commitments of $1.6 billion to other investments, and $12 million to privately held equity.

Guarantees

As of March 31, 2024, and December 31, 2023 parental guarantees supporting reinsurance obligations, defendant A&E liabilities, subsidiary capital support arrangements and credit facilities were $2.3 billion, for both periods. We also guarantee the 2040 and 2042 Junior Subordinated Notes, which have an aggregate principal amount of $850 million as of March 31, 2024 and December 31, 2023

Accounting Policies [Abstract]

Basis of Preparation

These unaudited condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the financial information and note disclosures required by U.S. GAAP for complete consolidated financial statements.

Basis of Consolidation

In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for a fair statement of the financial results for the interim periods. All intercompany accounts and transactions have been eliminated and certain comparative information has been reclassified to conform to the current presentation.

Recently Issued Accounting Pronouncements Not Yet Adopted

ASU 2023-07 - Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, which includes the following amendments to Topic 280 Segment Reporting:

•Disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within the segment measure of profit or loss;

•Disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition;

•Disclose, on an interim basis, all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280;

•Clarify that an entity is not precluded from reporting one or more additional measure(s) of segment profit or loss if the CODM uses more than one measure in assessing segment performance and deciding how to allocate resources;

•Disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources; and

•Require an entity with a single reportable segment to provide all disclosures required by the amendments in ASU 2023-07 and all existing segment disclosures in Topic 280.

These amendments are effective for annual reporting periods beginning after December 15, 2023 and interim reporting periods beginning after December 15, 2024, and must be applied retrospectively to all prior periods presented. Early adoption is permitted.

Adopting ASU 2023-07 will require us to expand our segment disclosures. We are currently determining the period in which the new guidance will be adopted.

ASU 2023-09 - Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, which includes the following amendments to Topic 740 Income Taxes:

•Disclose, on an annual basis, specific categories in the rate reconciliation;

•Disclose, on an annual basis, additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate);

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes;

•Disclose, on an annual basis, the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received);

•Disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign;

•Disclose income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign;

•Eliminates the requirement to disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or make a statement that an estimate of the range cannot be made; and

•Eliminates the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures.

These amendments are effective for annual reporting periods beginning after December 15, 2024, and should be applied prospectively, however retrospective application is permitted. Early adoption is permitted.

Adopting ASU 2023-09 will require us to expand our income tax disclosures. We are currently determining the period in which the new guidance will be adopted.

Investments

Funds Held

Under funds held arrangements, the reinsured company has retained funds that would otherwise have been remitted to us. The funds held balance is credited with investment income and losses paid are deducted.

We present funds held as a single category within the consolidated balance sheets.

Derivative Instruments

Freestanding Derivatives

Freestanding derivatives are recorded on trade-dates and carried on the consolidated balance sheet either as assets within other assets or as liabilities within other liabilities at estimated fair value. We do not offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting agreement.

If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are reported in fair value changes in trading securities, funds held and other investments included in our consolidated statements of operations.

Hedge Accounting

To qualify for hedge accounting, at the inception of the hedging relationship, we formally document the risk management objective and strategy for undertaking the hedging transaction, as well as the designation of the hedge.

We have qualifying net investment in foreign operation (“NIFO”) hedges. We recognize changes in the estimated fair value of the hedging derivatives within OCI, consistent with the translation adjustment for the hedged net investment in the foreign operation.

Our documentation sets forth how the hedging instrument is expected to hedge the designated risks related to the hedged item and also sets forth the method that will be used to retrospectively and prospectively assess the hedging instrument’s effectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk of the hedged item. Hedge effectiveness is formally assessed at inception and at least quarterly throughout the life of the designated hedging relationship. Assessments of hedge effectiveness are also subject to interpretation and estimation and different interpretations or estimates may have a material effect on the amount reported in net income.

When hedge accounting is discontinued pursuant to a NIFO hedge (due to a revaluation, payment of a dividend or the disposal of our investment in a foreign operation), the derivative continues to be carried on the balance sheet at its estimated fair value. Deferred gains and losses recorded in OCI pursuant to a discontinued NIFO hedge are recognized immediately in net foreign exchange losses (gains) in our consolidated statements of operations.

Embedded Derivatives

We are party to certain reinsurance agreements that have embedded derivatives. We also have embedded derivatives on our convertible bond portfolio, recorded within fixed maturities, trading on the consolidated balance sheets. We assess each identified embedded derivative to determine whether it is required to be bifurcated. The embedded derivative is bifurcated from the host contract and accounted for as a freestanding derivative if:

•the combined instrument is not accounted for in its entirety at estimated fair value with changes in estimated fair value recorded in net income;

•the terms of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract; and

•a separate instrument with the same terms as the embedded derivative would qualify as a derivative instrument.

Such embedded derivatives are carried on the consolidated balance sheet at estimated fair value with the host contract and changes in their estimated fair value are generally reported within fair value changes in trading securities, funds held and other investments.

Derivative Strategies

We are exposed to various risks relating to our ongoing business operations, including interest rate, foreign currency exchange rate, credit and equity price risks. We use a variety of strategies to manage these risks, including the use of derivatives.

Derivatives are financial instruments with values derived from interest rates, foreign currency exchange rates, credit spreads and/or other financial indices. The types of derivatives we use include swaps and forwards.

Foreign Currency Derivatives

We use foreign currency exchange rate derivatives, including foreign currency forwards, to reduce the risk from fluctuations in foreign currency exchange rates associated with our assets and liabilities denominated in foreign currencies. We also use foreign currency derivatives to hedge the foreign currency exchange rate risk associated with certain of our net investments in foreign operations.

In a foreign currency forward transaction, we agree with another party to deliver a specified amount of an identified currency at a specified future date. The price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. We utilize foreign currency forwards in fair value, NIFO hedges and nonqualifying hedging relationships.

Interest Rate Derivatives

We use interest rate derivatives, specifically interest rate swaps, to reduce our exposure to changes in interest rates.

Interest rate swaps are used by us primarily to reduce market risks from changes in interest rates and to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches). In an interest rate swap, we agree with another party to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts as calculated by reference to an agreed notional amount. We utilize interest rate swaps in nonqualifying hedging relationships.

Deferred Charges

If, at the inception of a retroactive reinsurance contract, the estimated liabilities for losses and LAE exceed the consideration received, a deferred charge asset (“DCA”) is recorded for this difference. In contrast, if the consideration received is in excess of the estimated undiscounted ultimate losses payable, a deferred gain liability (“DGL”) is recorded.

We amortize the net DCA balances over the estimated claim payment period of the related contracts with the amortization prospectively adjusted at each reporting period to reflect new estimates of the pattern and timing of remaining losses and LAE payments.

Losses and LAE

The liability for losses and LAE, also referred to as loss reserves, represents our gross estimates before reinsurance for unpaid reported losses (Outstanding Loss Reserves, or "OLR") and includes losses that have been incurred but not yet reported ("IBNR") using a variety of actuarial methods. We recognize an asset for the portion of the liability that we expect to recover from reinsurers. LAE reserves include allocated LAE ("ALAE") and unallocated LAE ("ULAE"). ALAE are linked to the settlement of an individual claim or loss, whereas ULAE are based on our estimates of future costs to administer the claims. IBNR includes amounts for unreported claims, development on known claims and reopened claims.

Our loss reserves cover multiple lines of business, including asbestos, environmental, general casualty, workers' compensation, marine, aviation and transit, construction defect, professional indemnity/directors and officers, motor, property and other non-life lines of business. We complete most of our annual loss reserve studies in the fourth quarter of each year and, as a result, tend to record the largest movements, both favorable and adverse, to net incurred losses and LAE in this period.

We have elected to apply the fair value option for certain reinsurance contracts including, loss portfolio transfers ("LPTs") and reinsurance to close ("RITC") transactions. This is an irrevocable election that applies to all balances under the reinsurance contract, including reinsurance balances recoverable on paid and unpaid losses and the liability for losses and LAE. The primary reason for electing the fair value option was to reduce the earnings volatility created by carrying the liabilities for losses and LAE at cost and the assets supporting those liabilities at fair value. During 2017 and 2018, we elected the fair value option on select new business and classified the supporting portfolio investments as trading securities, whereby all changes in fair value were recorded in the statements of operations. Commencing in 2019, we discontinued electing the fair value option on new business in order to better align with our evolving investment objectives.

Variable Interest Entities

We have investments in certain limited partnership funds which are deemed to be variable interest entities ("VIEs"). The activities of these VIEs are generally limited to holding investments and our involvement in these entities is passive in nature. We consolidate all VIEs in which we are considered to be the primary beneficiary.

Numerator:
Net income attributable to Enstar ordinary shareholders:	$	119	$	424
Denominator:
Weighted-average ordinary shares outstanding — basic (1)	14,641,158		16,980,240
Effect of dilutive securities:
Share-based compensation plans (2)	192,682		120,714
Weighted-average ordinary shares outstanding — diluted	14,833,840		17,100,954
Earnings per share attributable to Enstar ordinary shareholders:

Diluted	$	8.02	$	24.79

(1) Weighted-average ordinary shares for basic earnings per share includes ordinary shares (voting and non-voting), but excludes ordinary shares held in the Enstar Group Limited Employee Benefit Trust (the "EB Trust") in respect of Joint Share Ownership Plan ("JSOP") awards, which, as a result of us consolidating the EB trust, are classified as treasury shares.

(2) Share-based dilutive securities include restricted shares, restricted share units, directors’ restricted share units and performance share units. Certain share-based compensation awards were excluded from the calculation for the three months ended March 31, 2024 and 2023 because they were anti-dilutive.
