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, 2022, which could cause actual results to differ materially from those suggested by the forward-looking statements. These 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;

•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;

•increased competitive pressures, including increased competition in the market for acquisitions of run-off business;

•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;

•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;

•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;

•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;

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

•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);

•the effects of inflation, including its impact on our loss cost trends and operating expenses, and the effects of global economic policy responses to inflation, such as increasing interest rates and their impact on our investment portfolio;

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

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

•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;

6

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

•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;

•loss of key personnel;

•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;

•tax, regulatory or legal restrictions or limitations applicable to us or the (re)insurance business generally;

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

•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, 2022. 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.

Item 2 | Management's Discussion and Analysis | Operational Highlights

Operational Highlights

Our consolidated results reflect our ongoing provision of capital release solutions to our clients by acquiring and managing seasoned liabilities relating to both their continuing and discontinued portfolios.

Operational highlights for the six months ended June 30, 2023 include:

Transactions

•In April 2023, certain of our wholly-owned subsidiaries completed a LPT agreement with certain subsidiaries of QBE Insurance Group Limited (“QBE”), relating to a diversified portfolio of business underwritten between 2010 and 2020. Upon closing, a portion of the portfolio currently underwritten via QBE’s Lloyd’s Syndicates 386 and 2999 was reinsured to Enstar’s Syndicate 2008.

As a result of this LPT transaction, we assumed net loss reserves of $2.0 billion in exchange for consideration of $1.9 billion1, and recorded a $179 million deferred charge asset (“DCA”).

•In June 2023, one of our wholly-owned subsidiaries completed an agreement with RACQ Insurance Limited (“RACQ”) to reinsure 80% of RACQ’s motor vehicle Compulsory Third Party (“CTP”) insurance liabilities, covering accident years 2021 and prior.

At closing, we assumed net loss reserves of $179 million in exchange for consideration of $179 million1.

•During the second quarter of 2023, we assumed active claims management control on a 2022 LPT transaction with Argo Group International Holdings, Ltd. (“Argo”) pursuant to terms of the agreement.

Completed Unwind of Enhanzed Re’s Reinsurance Transactions

•In November 2022, our subsidiary Enhanzed Reinsurance Ltd. (“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”).

◦Given our one quarter lag in reporting Enhanzed Re’s results, we recognized a $275 million net gain on novation within other income in the first quarter of 2023, which was comprised of2:

▪the reclassification benefit to income of $363 million from accumulated other comprehensive income (“AOCI”) related to the settlement of the novated future policyholder benefit liabilities;

▪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; and

▪a deferral of a portion of the net gain, equal to $49 million, for our preexisting 20% ownership interest in Monument Re.

◦Our net earnings attributable to Enstar were further reduced by $81 million, representing the amount attributable to Allianz SE’s (“Allianz”) 24.9% noncontrolling interest in Enhanzed Re at the time of the transaction. In total, first quarter 2023 net earnings attributable to Enstar from this novation transaction were $194 million.

•On December 28, 2022, Enhanzed Re repurchased the entire 24.9% ownership interest Allianz held in Enhanzed Re for $175 million, which was based on the final net book value of Enhanzed Re as of December 31, 2022. Enhanzed Re is now a wholly-owned subsidiary of Enstar.

•Following the completion of these transactions, we concluded the unwind of Enhanzed Re, achieving an inception to date return from Enhanzed Re of 24%.

Primary GAAP Financial Measures

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

•Net earnings and net earnings attributable to Enstar ordinary shareholders, which 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 earnings attributable to Enstar ordinary shareholders by Enstar ordinary shareholders’ equity;

•Total investment return (“TIR”), which measures the rate of return we obtain, both realized and unrealized, 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 net incurred losses and LAE by our average net loss reserves (RLE %).

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

Overall Results

Three Months Ended June 30, 2023 versus 2022:

Net earnings attributable to Enstar ordinary shareholders for the three months ended June 30, 2023 were $21 million, in comparison to a net loss of $434 million in the comparative quarter, as a result of:

•A favorable total investment return of $159 million for the three months ended June 30, 2023, in comparison to a negative total investment return of $522 million for the comparative quarter, consisting of the aggregate of net investment income, net realized gains (losses), net unrealized gains (losses) and earnings from equity method investments. The total investment return was driven by:

◦Net realized and unrealized gains on our other investments, including equities of $62 million, in comparison to net realized and unrealized losses in the comparative quarter of $220 million, as a result of improved global equity market performance and tightening of high yield credit spreads for the three months ended June 30, 2023;

◦An increase in net investment income of $66 million, consistent with the increasing investment income we have earned on a sequential quarterly basis, primarily due to reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first half of 2023 and the impact of rising interest rates on our fixed maturities securities that are subject to floating interest rates; and

◦Net realized and unrealized losses on our fixed maturities of $89 million for the three months ended June 30, 2023, compared to net realized and unrealized losses on our fixed maturities of $409 million for the three months ended June 30, 2022. The net result for the three months ended June 30, 2023 was favorable on a comparative basis due to the significant increase in interest rates that occurred during the comparative quarter.

This was partially offset by:

•A decrease of $149 million in favorable development in net incurred losses and LAE for prior periods in comparison to the three months ended June 30, 2022. Second quarter 2023 net favorable development of $10 million was primarily due to a reduction in our estimates of net ultimate losses of $8 million and an $8 million decrease in the fair value of our 2017 and 2018 LPT liabilities where we elected the fair value option, partially offset by fair value adjustment (“FVA”) amortization. Second quarter 2022 net favorable development of $159 million was primarily due to a reduction in our estimates of net ultimate losses and provisions for ULAE of $116 million and a $48 million reduction in the fair value of liabilities where we elected the fair value option due to an increase in second quarter 2022 interest rates. This resulted in RLE of 0.1% for the three months ended June 30, 2023 in comparison to RLE of 1.3% in the comparative quarter.

The above factors contributed to net earnings of $39 million for the three months ended June 30, 2023 as compared to a net loss of $467 million in the comparative quarter, as well as net earnings attributable to Enstar ordinary shareholders of $21 million as compared to net losses attributable to Enstar ordinary shareholders of $434 million in the comparative quarter.

As a result of the current quarter net earnings attributable to Enstar as noted above, our ROE increased by 8.7 pp.

Comprehensive income attributable to Enstar for the three months ended June 30, 2023 was $38 million as compared to comprehensive net loss of $557 million in the comparative quarter. The second quarter 2023 comprehensive income was primarily due to net earnings of $39 million and an out of period adjustment to reclassify $21 million for the change in net incurred losses and LAE relating to our credit risk3 (which is a component of the discount rate), partially offset by unrealized losses on fixed maturities, AFS, net of reclassification adjustments, of $9 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 3.0% for the three months ended June 30, 2023, in comparison to a negative Annualized TIR of (15.2)% in the comparative quarter.

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

3 The impact of the out of period adjustment increased net incurred losses and LAE by $21 million and other comprehensive income (“OCI”) by $21 million, which had a net neutral impact on total comprehensive income.

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

Six Months Ended June 30, 2023 versus 2022:

Net earnings attributable to Enstar ordinary shareholders for the six months ended June 30, 2023 were $445 million, in comparison to a net loss of $701 million in the comparative period, as a result of:

•A favorable total investment return of $514 million for the six months ended June 30, 2023, in comparison to a negative total investment return of $829 million for the comparative period, consisting of the aggregate of net investment income, net realized gains (losses), unrealized gains (losses) and earnings from equity method investments. The total investment return was primarily driven by:

◦Net realized and unrealized gains on our other investments, including equities of $209 million, in comparison to net realized and unrealized losses in the comparative period of $304 million, as a result of strong global equity market performance, particularly in the first quarter of 2023, and tightening high yield credit spreads for the six months ended June 30, 2023, compared to the challenging market environment for the six months ended June 30, 2022;

◦An increase in net investment income of $142 million, consistent with the increasing investment income we have earned on a sequential quarterly basis, primarily due to reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first half of 2023 and the impact of rising interest rates on our fixed maturities that are subject to floating interest rates; and

◦Net realized and unrealized losses on our fixed maturities of $48 million for the six months ended June 30, 2023, in comparison to net realized and unrealized losses in the comparative period of $743 million. The net result was favorable on a comparative basis due to the significant increase in interest rates that occurred during the first half of 2022.

•An increase in other income of $245 million, largely driven by the net gain recognized from the novation of the Enhanzed Re reinsurance of a closed block of life annuity policies.

This was partially offset by:

•A decrease of $315 million in favorable development in net incurred losses and LAE for prior periods in comparison to the prior year comparative period. First half 2023 net favorable development of $20 million was primarily due to a reduction in our estimates of net ultimate losses and provisions for ULAE of $41 million, partially offset by a $12 million increase in the fair value of our 2017 and 2018 LPT liabilities where we elected the fair value option. First half 2022 net favorable development of $335 million was primarily due to a reduction in our estimates of net ultimate losses and provisions for ULAE of $196 million and a $146 million reduction in the fair value of liabilities where we elected the fair value option due to an increase in interest rates during the six months ended June 30, 2022. This resulted in RLE of 0.2% for the six months ended June 30, 2023 in comparison to RLE of 2.7% in the comparative period; and

•Net earnings attributable to noncontrolling interests of $95 million, in comparison to a net loss of $31 million in the comparative period, as a result of recording the portion of the gain on novation of the Enhanzed Re reinsurance of a closed block of life annuity policies attributable to Allianz’s equity interest in Enhanzed Re.

The above factors contributed to net earnings of $558 million for the six months ended June 30, 2023 as compared to a net loss of $714 million in the comparative period, as well as net earnings attributable to Enstar ordinary shareholders of $445 million as compared to net losses attributable to Enstar ordinary shareholders of $701 million in the comparative period.

As a result of the current period net earnings attributable to Enstar as noted above, our ROE increased by 22.1 pp.

Comprehensive income attributable to Enstar for the six months ended June 30, 2023 was $277 million as compared to comprehensive net loss of $1.0 billion in the comparative period. First half 2023 comprehensive income was primarily due to net earnings of $558 million, partially offset by the reclassification adjustment of $363 million associated with the novation described above. Unrealized gains on our fixed maturities, AFS combined with our favorable investment return, described above, contributed to favorable Annualized TIR of 6.1% for the six months ended June 30, 2023, in comparison to a negative Annualized TIR of (12.8)% in the comparative period.

BVPS and Adjusted BVPS* increased by 8.6% and 7.9%, respectively, from December 31, 2022 to June 30, 2023, due to comprehensive income attributable to Enstar for the six months ended June 30, 2023, which contributed 6.2% to both BVPS and Adjusted BVPS*, combined with the repurchase of all our non-voting convertible ordinary shares at a discount to year-end book value.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 14

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

BVPS and Adjusted BVPS* as of December 31, 2022 reported in this Quarterly Report on Form 10-Q reflect the impact of our adoption of ASU 2018-12, which had the effect of retrospectively increasing such measures by $16.04 and $15.83, respectively, from the amounts reported in our Annual Report on Form 10-K for the year ended December 31, 2022. The higher opening BVPS and Adjusted BVPS* for the year negatively impacted our growth in BVPS and Adjusted BVPS* for the six months ended June 30, 2023, which would have otherwise been 15.7% and 14.9%, respectively. Our future policyholder benefit liabilities, which were adjusted for the retrospective application of ASU 2018-12, were settled in the fourth quarter of 2022 following the completion of the novation as described above, but the transaction was recognized in the first quarter of 2023 as we report the results of Enhanzed Re on a one quarter lag. Consequently, the adoption of ASU 2018-12 had no impact on our BVPS or Adjusted BVPS* as of June 30, 2023.

Similarly, at the time the repurchase of our non-voting convertible ordinary shares was negotiated, the price represented a 13.0% discount to year-end book value as reported in our Annual Report on Form 10-K for the year ended December 31, 2022. Following the adoption of ASU 2018-12 on a retrospective basis, the price paid in the repurchase transaction represented a 23.0% discount to year-end book value as reported in our Quarterly Report on Form 10-Q for the three and six months ended June 30, 2023.

Overall Measures of Performance

BVPS and Adjusted BVPS*

BVPS and Adjusted BVPS* increased by 8.6% and 7.9%, respectively, from December 31, 2022 to June 30, 2023, primarily as a result of comprehensive income attributable to Enstar of $277 million for the six months ended June 30, 2023 and the repurchase of our non-voting convertible ordinary shares at a discount to year-end book value. The adoption of ASU 2018-12 impacted our BVPS and Adjusted BVPS as of December 31, 2022, as described above.

ROE and Adjusted ROE*

Three and Six Months Ended June 30, 2023 versus 2022: ROE increased by 8.7 and 22.1 pp for the three and six months ended June 30, 2023, respectively, primarily due to:

i.decreased net realized and unrealized losses on our fixed maturities for the three and six months ended June 30, 2023 compared to net losses for the equivalent periods ended June 30, 2022, respectively. This contributed 5.7 and 11.7 pp to the increase in ROE for the three and six months ended June 30, 2023, respectively;

ii.net realized and unrealized gains on other investments, including equities, for the three and six months ended June 30, 2023 compared to net losses for the equivalent periods ended June 30, 2022, respectively. This contributed 5.6 and 9.9 pp to the increase in ROE for the three and six months ended June 30, 2023, respectively;

iii.increased other income, comprised primarily of the gain recognized on the novation of the Enhanzed Re reinsurance of a closed block of life annuity policies, which contributed 5.7 pp to the increase in ROE for the six months ended June 30, 2023; and

iv.increased net investment income, which contributed 1.9 and 4.1 pp to the increase in ROE for the three and six months ended June 30, 2023, respectively.

These favorable factors were partially offset by:

iv. decreased favorable prior period development, or RLE, which offset the increase in ROE by 2.8 and 5.3 pp for the three and six months ended June 30, 2023, respectively; and

v.     increased earnings attributable to noncontrolling interests, which offset the increase in ROE by 1.0 and 2.7 pp for the three and six months ended June 30, 2023, respectively.

Adjusted ROE* increased by 3.7 and 11.3 pp for the three and six months ended June 30, 2023, respectively, as it excludes the impact of net realized and unrealized gains (losses) on our 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 condensed consolidated statements of earnings, 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:

•Underwriting results: includes net premiums earned, net incurred losses and LAE, policyholder benefit expenses and acquisition costs.

•Investment results: includes net investment income, net realized (losses) gains, net unrealized gains (losses) (recorded through the condensed statements of earnings and other comprehensive income) and earnings (losses) from equity method investments.

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

Underwriting 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.

Although we have largely exited our active underwriting platforms, we still record net premiums earned and the associated current period net incurred losses and LAE and acquisition costs as a result of the run-off 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 underwriting results are as follows:

Our RLE % was insignificant for the three months ended June 30, 2023, as favorable reductions in estimates of net ultimate losses and changes in the fair value of liabilities for which we have elected the fair value option were largely offset by amortization of fair value adjustments.

Favorable RLE in the 2017 acquisition year was driven predominantly by a reduction in the fair value of liabilities for which we have elected the fair value option, partially offset by an adjustment to reclassify the change in net incurred losses and LAE relating to our credit risk.

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

Adverse RLE in the 2022 acquisition year was driven by an increase in ULAE provisions as a result of assuming active claims management control on a 2022 LPT transaction with Argo.

Our Adjusted RLE %* was positively impacted by the net reduction in estimates of net ultimate losses 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.

Net Investment Income

The below charts are in millions of U.S. dollars.

Three Months Ended June 30, 2023 versus 2022: Net investment income increased primarily due to:

•an increase in our annualized investment book yield from 2.32% to 4.47% due to a combination of reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first half of 2023 and the impact of rising interest rates on the $3.1 billion of our fixed maturity investments that are subject to floating interest rates. Our floating rate investments generated net investment income of $63 million for the three months ended June 30, 2023, an increase of $28 million from the second quarter of 2022, which equates to an increase in the annualized yield of those investments of 326 basis points.

Six Months Ended June 30, 2023 versus 2022: Net investment income increased primarily due to:

•an increase in our annualized investment book yield from 2.03% to 3.78% due to a combination of reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first half of 2023 and the impact of rising interest rates on the $3.1 billion of our fixed maturity investments that are subject to floating interest rates. Our floating rate investments generated net investment income of $119 million for the six months ended June 30, 2023, an increase of $56 million from the first half of 2022, which equates to an increase in the annualized yield of those investments of 346 basis points.

Net Realized and Unrealized (Losses) Gains Included in Comprehensive Income

The below charts are in millions of U.S. dollars.

Three Months Ended June 30, 2023 versus 2022: Net realized and unrealized losses included in comprehensive income decreased relative to the prior quarter primarily due to:

•a decrease in net realized and unrealized losses on fixed maturities of $528 million, primarily as a result of a comparatively less significant increase in interest rates across U.S., U.K. and European markets relative to the prior year quarter and tightening of credit spreads for the three months ended June 30, 2023; and

•net realized and unrealized gains on other investments, including equities, of $62 million for the three months ended June 30, 2023, compared to net losses of $220 million for the comparative quarter.

◦Net gains for the three months ended June 30, 2023 were primarily driven by our public equities, private equity funds, fixed income funds and private credit funds, largely as a result of global equity market performance and tightening of high yield credit spreads; in comparison to

◦Net losses for the three months ended June 30, 2022 that were primarily driven by our fixed income funds, public equities and CLO equities, largely as a result of global equity market declines and the widening of high yield credit spreads. This was partially offset by gains on our private equity funds, private credit funds and real estate funds for the three months ended June 30, 2022, which are typically recorded on a one quarter lag.

Six Months Ended June 30, 2023 versus 2022: Net realized and unrealized gains included in comprehensive income increased relative to the prior period net realized and unrealized losses primarily due to:

•net realized and unrealized gains on fixed maturities of $17 million, compared to net losses of $1.2 billion for the comparative period, as a result of a comparatively less significant increase in interest rates across U.S., U.K. and European markets relative to the prior year period and tightening of credit spreads for the six months ended June 30, 2023; and

•net realized and unrealized gains on other investments, including equities, of $209 million for the six months ended June 30, 2023, compared to net losses of $304 million for the comparative period. The favorable movement of $513 million was primarily driven by:

◦Net gains for the six months ended June 30, 2023 that were primarily driven by our public equities, private equity funds, private credit funds and fixed income funds, largely as a result of strong global equity market performance and tightening high yield credit spreads; in comparison to

◦Net losses for the six months ended June 30, 2022 that were primarily driven by our fixed income funds, public equities and CLO equities, largely as a result of global equity market declines and the widening of high yield credit spreads.

Earnings from equity method investments

The below charts are in millions of U.S. dollars.

Three Months Ended June 30, 2023 versus 2022: Earnings from equity method investments increased by $13 million, due to earnings of $7 million, $5 million and $2 million from our investments in Core Specialty, Monument Re and Citco for the three months ended June 30, 2023, respectively. The second quarter 2023 Monument Re earnings included an $8 million adjustment for information received from Monument Re pertaining to the first quarter 2023. In comparison, earnings of $7 million from our investment in Monument Re and $1 million in Citco were offset by losses of $7 million from our investment in Core Specialty for the three months ended June 30, 2022.

Six Months Ended June 30, 2023 versus 2022: Earnings from equity method investments decreased by $7 million, primarily due to a $27 million decrease in earnings from our investment in Monument Re for the six months ended June 30, 2023. The decrease was partially offset by earnings of $18 million from our investment in Core Specialty for the six months ended June 30, 2023.

Investable Assets

Investable assets and adjusted investable assets* decreased by 1.6% and 5.2% from December 31, 2022 to June 30, 2023, respectively, primarily due to:

•the novation of the Enhanzed Re reinsurance of a closed block of life annuity policies (and the associated assets of $949 million);

•the impact of net paid losses;

•the repurchase of our non-voting convertible ordinary shares; and

•the settlement of our participation in Atrium’s Syndicate 609 relating to the 2020 and prior underwriting years.

Partially offset by:

•consideration received for the QBE and RACQ LPT transactions; and

•net unrealized gains on our fixed income assets and other investments, including equities.

Duration and average credit rating on fixed maturities and cash and cash equivalents

The fair value, duration and average credit rating of investments by segment is as follows:

	June 30, 2023				December 31, 2022
Segment	Fair Value ($) (1)		Average Duration (in years) (2)	Average Credit Rating (3)	Fair Value ($) (1)		Average Duration (in years) (2)	Average Credit Rating (3)

Legacy Underwriting	—		n/a		179		2.26	AA-
Total	$	11,005	3.76	A+	$	10,961	4.40	A+

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

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

The overall increase in the balance of our fixed maturities and cash and cash equivalents of $44 million for the six months ended June 30, 2023 was primarily driven by the consideration received in relation to the QBE and RACQ LPT transactions, partially offset by the derecognition of the assets supporting the Enhanzed Re reinsurance of a closed block of life annuity policies that were novated during the first quarter of 2023, the impact of net paid losses, the settlement of our participation in Atrium’s Syndicate 609 relating to the 2020 and prior underwriting years and the repurchase of our non-voting convertible ordinary shares.

The decrease in the average duration of our fixed maturities and cash and cash equivalents for the six months ended June 30, 2023 was primarily driven by the consideration received for the QBE LPT, which has a shorter average duration, increases in interest rates and the derecognition of the assets supporting the Enhanzed Re reinsurance of a closed block of life annuity policies that were novated during the first quarter of 2023.

As of both June 30, 2023 and December 31, 2022, our fixed maturities and cash and cash equivalents had an average credit quality rating of A+.

As of June 30, 2023 and December 31, 2022, our fixed maturities that were non-investment grade (i.e. rated lower than BBB- and non-rated securities) comprised $469 million, or 4.7% and $622 million, or 6.5% of our total fixed maturities portfolio, respectively.

The below charts are in millions of U.S. dollars.

Three Months Ended June 30, 2023 versus 2022: The $2 million increase in general and administrative expenses was primarily driven by an increase in salaries and benefits expenses, driven by an increase in long-term incentive plan costs, partially offset by a decrease in professional fees driven by the wind down of Enhanzed Re operations.

Six Months Ended June 30, 2023 versus 2022: The $6 million increase in general and administrative expenses was primarily driven by increases in salaries and benefits expenses, driven by an increase in long-term incentive plan costs, and increases in bank facility fees.

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 and unrealized (gains)/losses on fixed maturity investments recognized in our income statement, 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
Adjusted 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 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 net realized and unrealized (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 earnings 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 earnings 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 earnings (loss) attributable to Enstar ordinary shareholders, adjusted for: -net realized and unrealized (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 earnings from discontinued operations (if any), -tax effects of adjustments, and -adjustments attributable to noncontrolling interests

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(2); as such, the results were not a relevant contribution to Adjusted RLE, which is designed to analyze the impact of our claims management strategies;   •The results of our Assumed Life segment relate only to our prior exposure to active property catastrophe business; as this business was not in run-off, the results were not a relevant contribution to Adjusted RLE;   •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 and Assumed Life 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 and Assumed Life 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 earnings 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: -net realized and unrealized (gains) losses on fixed maturities 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 -net unrealized (gains) losses on fixed maturities, trading

Item 2 | Management's Discussion and Analysis | Other Financial Measures

Other Financial Measures

In addition to our non-GAAP financial measures presented above, we refer to TIR, which provides a key measure of the return generated on the capital held in the business. It is reflective of our investment strategy and it provides a consistent measure of investment returns as a percentage of all assets generating investment returns.

The following tables provide the calculation of our Annualized TIR by reporting segment:

Overall Results

Three Months Ended June 30, 2023 versus 2022: Net loss from our Run-off segment was $34 million compared to net earnings of $78 million in the comparative quarter, primarily due to:

•A $113 million decrease in favorable PPD in the current quarter, mainly driven by a $100 million decrease in the reduction in estimates of net ultimate losses in comparison to the comparative quarter.

◦During the second quarter of 2023, we recognized favorable development of $9 million on our workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

◦We also increased our ULAE provision by $21 million as a result of assuming active claims control on our 2022 LPT agreement with Argo, which offset other ULAE reserve adjustments from our run-off operations.

◦In comparison, during the second quarter of 2022 we recognized favorable development of $78 million and $16 million on our professional indemnity/directors and officers and workers’ compensation lines of

business, respectively, as a result of favorable loss activity, most notably in the 2021 acquisition year; partially offset by

•Reductions in current quarter net incurred losses and LAE and acquisition costs that were greater than the reductions in net premiums earned, following our exit of our StarStone International business beginning in 2020.

Six Months Ended June 30, 2023 versus 2022: Net loss from our Run-off segment was $39 million compared to net earnings of $97 million in the comparative period, primarily due to:

•A $130 million decrease in favorable PPD, mainly driven by a $114 million decrease in the reduction in estimates of net ultimate losses in comparison to the comparative period.

◦We recognized favorable development of $20 million on our workers’ compensation line of business during the first half of 2023 as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

◦We also increased our ULAE provision by $21 million as a result of assuming active claims control on our 2022 LPT agreement with Argo, which offset other ULAE reserve adjustments from our run-off operations.

◦In comparison, during the first half of 2022, we recognized favorable development of $81 million and $50 million on our professional indemnity/directors and officers and workers’ compensation lines of business, respectively, as a result of favorable loss activity, most notably in the 2021 acquisition year; partially offset by

•Reductions in current period net incurred losses and LAE and acquisition costs that were greater than the reductions in net premiums earned, following our exit of our StarStone International business beginning in 2020.

Assumed Life Segment

The Assumed Life segment consists of life and property aggregate excess of loss (catastrophe) business relating to Enhanzed Re, which we have consolidated since September 1, 2021 following the completion of a step acquisition that increased our ownership interest to 75.1%. We report the Enhanzed Re component results of this segment on a one quarter lag.

The Enhanzed Re catastrophe business was not renewed for 2022. During the third quarter of 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.

Following the completion of the transactions, we have ceased all continuing reinsurance obligations for this segment. We may leverage this segment for any future potential assumed life business transactions if and when they occur.

The following is a discussion and analysis of the results of operations for our Assumed Life segment.

Overall Results

Three and Six Months Ended June 30, 2023 versus 2022: As discussed above, we ceased all continuing reinsurance obligations relating to our Assumed Life segment following the completion of the transactions pursuant to the Master Agreement, and did not record any transactions in the segment during the second quarter of 2023. The increase in net earnings from our Assumed Life segment of $253 million for the six months ended June 30, 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, 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);

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

•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 earnings attributable to Enstar were 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 half 2023 net earnings attributable to Enstar from this novation transaction were $194 million.

Overall Results

Three Months Ended June 30, 2023 versus 2022: Net earnings from our Investments segment were $149 million for the three months ended June 30, 2023 compared to net losses of $532 million for the three months ended June 30, 2022. The favorable movement of $681 million was primarily due to:

•a decrease in net realized and unrealized losses on fixed maturities of $318 million, primarily as a result of a less significant increase in interest rates across U.S., U.K. and European markets and tightening of credit spreads relative to the comparable quarter;

•net realized and unrealized gains on other investments, including equities, of $62 million, compared to net realized and unrealized losses of $220 million in the comparative period. The favorable variance of $282 million was primarily driven by:

◦Net gains for the three months ended June 30, 2023, primarily driven by our public equities, private equity funds, fixed income funds and private credit funds, largely as a result of global equity market performance and tightening high yield credit spreads; in comparison to

◦Net losses for the three months ended June 30, 2022, primarily driven by our fixed income funds, public equities and CLO equities, largely as a result of global equity market declines and the widening of high yield credit spreads. This was partially offset by gains on our private equity funds, private credit funds and real

estate funds for the three months ended June 30, 2022, which are typically recorded on a one quarter lag; and

•an increase in our net investment income of $68 million, which is primarily due to the reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first half of 2023 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 increased net investment income of $28 million, which equates to an increase of 326 basis points on those investments in comparison to the prior quarter.

Six Months Ended June 30, 2023 versus 2022: Net earnings from our Investments segment was $493 million for the six months ended June 30, 2023 compared to net losses of $846 million for the six months ended June 30, 2022. The favorable movement of $1.3 billion was primarily due to:

•a decrease in net realized and unrealized losses on fixed maturities of $687 million, primarily driven by a net decline in interest rates and tightening of credit spreads in the current period, in comparison to an increase in interest rates across U.S., U.K. and European markets and widening of credit spreads in the prior period;

•net realized and unrealized gains on other investments, including equities, of $209 million, compared to net realized and unrealized losses of $304 million in the comparative period. The favorable variance of $513 million was primarily driven by:

◦Net gains for the six months ended June 30, 2023, primarily from our public equities, private equity funds, private credit funds and fixed income funds, largely as a result of strong global equity market performance and tightening of high yield credit spreads; in comparison to

◦Net losses for the six months ended June 30, 2022, driven by our fixed income funds, public equities, hedge funds and CLO equities, largely as a result of global equity market declines and the widening of high yield credit spreads. This was partially offset by gains on our private equity funds, private credit funds and real estate funds, which are typically recorded on a one quarter lag; and

•an increase in our net investment income of $148 million, which is primarily due to the reinvestment of fixed maturities at higher yields, deployment of consideration received from deals closed in the second half of 2022 and the first six months of 2023 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 increased net investment income of $56 million, which equates to an increase of 346 basis points on those investments in comparison to the prior period.

The overall increase in the balance of our fixed maturities of $347 million for the six months ended June 30, 2023 was primarily driven by the consideration received for the QBE and RACQ LPT transactions that closed during the second quarter of 2023, partially offset by the derecognition of the assets supporting the Enhanzed Re reinsurance closed block of life annuity policies that were novated during the first quarter of 2023, the impact of net paid losses and the repurchase of our non-voting convertible ordinary shares.

(2) We own 20.0% of the common shares in Monument Re as well as preferred shares which have a fixed dividend yield and whose balance is included in the Investment amount.

Carrying Value

The carrying value of our equity method investments increased from December 31, 2022, largely due to $25 million in earnings from equity method investments for the six months ended June 30, 2023.

Earnings from Equity Method Investments

Three Months Ended June 30, 2023 versus 2022: Earnings from equity method investments increased by $13 million, primarily due to earnings of $7 million, $5 million and $2 million from our investments in Core Specialty, Monument Re and Citco for the three months ended June 30, 2023, respectively. The second quarter 2023 Monument Re earnings included an $8 million adjustment for information received from Monument Re pertaining to the first quarter 2023. In comparison, earnings of $7 million from our investment in Monument Re and $1 million from Citco were offset by losses of $7 million from our investment in Core Specialty for the three months ended June 30, 2022.

Six Months Ended June 30, 2023 versus 2022: Earnings from equity method investments decreased by $7 million, primarily due to a $27 million decrease in earnings from our investment in Monument Re for the six months ended June 30, 2023. The decrease was partially offset by earnings of $18 million from our investment in Core Specialty for the six months ended June 30, 2023.

Overall Results

Three Months Ended June 30, 2023 versus 2022:

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

As of January 1, 2021, SGL No.1 settled its share of the 2020 and prior underwriting years for the economic benefit of Atrium, and there was no net retention by Enstar.

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. As a result of the settlement, we do not expect to record any transactions in the Legacy Underwriting segment in 2023.

Overall Results

Three Months Ended June 30, 2023 versus 2022: Net loss attributable to Enstar ordinary shareholders from our Corporate and other activities was $94 million for the three months ended June 30, 2023, compared to net earnings of $27 million for the comparative quarter, primarily due to:

•Net earnings attributable to noncontrolling interests of $9 million, in comparison to net losses attributable to noncontrolling interests of $42 million for the comparative quarter, as a result of net earnings and losses recorded in the second quarters of 2023 and 2022, respectively, for those consolidated entities where there are noncontrolling interests;

•Changes in the fair value of the 2017 and 2018 portfolios where we elected the fair value option resulted in a $8 million decrease in liabilities in the second quarter of 2023, in comparison to a $48 million reduction of such liabilities in the comparative quarter, due to a less significant increase in interest rates in the current quarter in comparison to the second quarter of 2022;

•Other expense of $3 million in the current quarter in comparison to other income of $14 million in the comparative quarter, an unfavorable change of $17 million; and

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

•Net foreign exchange losses of $5 million, primarily driven by the impact of current quarter GBP strengthening against the U.S. dollar on our net liability exposures, in comparison to net gains of $13 million in the second quarter of 2022, which were primarily driven by the impact of U.S. dollar strengthening against the Euro on our Euro-denominated net liabilities relating to the Enhanzed Re reinsurance closed block of life annuity policies (which were novated during the first quarter of 2023).

Six Months Ended June 30, 2023 versus 2022: Net loss attributable to Enstar ordinary shareholders from our Corporate and other activities was $284 million for the six months ended June 30, 2023, compared to net earnings of $26 million for the comparative period, primarily due to:

•Changes in the fair value of the 2017 and 2018 portfolios where we elected the fair value option resulted in a $12 million increase in liabilities in the first half of 2023, in comparison to a $146 million reduction of such liabilities in the comparative period, driven by a significant increase in interest rates during the first half of 2022.

•Net earnings attributable to noncontrolling interests of $95 million in the current period in comparison to the attribution of net losses of $31 million in the comparative period, which 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;

•Other expense of $3 million in the current period in comparison to other income of $17 million in the comparative period, an unfavorable change of $20 million; and

•A decrease in net foreign exchange gains of $9 million, due to insignificant net gains in the current period in comparison to net gains of $10 million in the comparative period, which were primarily driven by the impact of U.S. dollar strengthening against the Euro on our Euro-denominated net liabilities relating to the Enhanzed Re reinsurance closed block of life annuity policies (which were novated during the first quarter of 2023).

Current Outlook

Run-off Outlook

Transactions

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.

We expect we will invest a significant portion of consideration received on new transactions in fixed maturities, which will deliver accretive investment book yields at the current elevated rates.

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 through 2023 and into 2024 as a result of persistent inflationary pressures and the corresponding tightening of financial conditions by global central banks, a potential economic recession 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 address inflation while simultaneously navigating events posing risks to financial stability. In the event that interest rates continue to rise and/or credit spreads widen, we may recognize unrealized losses 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;

•We hold approximately 16% of our portfolio in individual fixed maturities that have floating interest rates which, should interest rates remain elevated, we expect to be accretive to future investment book yields. We have earned $63 million and $34 million of net investment income from our floating rate investments for the three months ended June 30, 2023 and 2022, respectively, and $119 million and $63 million for the six months ended June 30, 2023 and 2022, respectively, which were generally indexed to LIBOR4 through June 30, 2023.

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

We expect that the unrealized losses we recognized on our fixed maturities over the prior year will be recouped as these assets get closer to their maturity and the prices pull to par. We may also undertake tactical repositioning of our portfolio as opportunities arise to achieve better investment yields, rather than waiting for certain fixed maturities to pull to par value, which may result in the recognition of previously unrealized losses within our income statement with a corresponding reclassification adjustment in other comprehensive income (neutral to equity).

Despite a stronger than expected start to the year, global equity markets are expected to remain volatile through the remainder of 2023, and this, combined with our reporting lag on certain investments, may impact the valuation of our non-core risk investments. We invest in public and private assets, which may vary in the magnitude of their exposure to any potential economic recession.

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

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 51

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

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

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 and will continue to seek other attractive investment opportunities throughout 2023.

Inflation

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

Our Run-off net loss reserves primarily consist of general casualty, workers’ compensation and asbestos lines of business which, as long tailed lines of business, have not been significantly impacted by ongoing inflationary pressures in comparison to other lines of business, such as property and auto lines.

The currently observed and limited impact of economic inflation on our loss cost trends reflects a combination of the opportunity we have to re-price seasoned books of business upon their acquisition and our claims management model that seeks to settle claims in an efficient and responsive manner to protect and mitigate the impact to us from adverse outcomes.

While we do not currently see any new trends in the longer term trend of social inflation on certain claims, we continue to monitor claims in difficult legislative districts, seek to actively settle claims and monitor for reserving adequacy.

As described above, global economic policy responses to inflation have led 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.

There remains uncertainty around the pace and direction 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.

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.

Banking Volatility

Following the recent instability in the banking sector, we performed an analysis of, and continue to monitor, our investments, deposits, underwriting risks, LOC capacity and availability, and any other direct and indirect exposures we may have to the impacted U.S. regional banks and Credit Suisse Group AG. We have not identified any material direct or indirect exposures to date.

Russian Invasion of Ukraine

The Russian invasion of Ukraine and the resulting impact on global commodity markets has increased commodity prices, disrupted supply chains and generated significant insurance losses. In response, many countries have established comprehensive sanctions regimes increasing both geopolitical tension between NATO and Russia and market volatility.

We continue to monitor our direct investment and underwriting risks and our acquisition pipeline. To date, the invasion has not caused any operational disruption to us and our third party service providers. We have no significant direct impacts from this event. We also continue to monitor for, and respond to, all changes in the global sanctions regime, updating our procedures accordingly.

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

Liquidity and Capital Resources

Overview

We aim to generate cash flows from our (re)insurance operations and investments, preserve sufficient capital for future acquisitions and new business, and develop relationships with lenders who provide borrowing capacity at competitive rates.

Liquidity and Capital Resources Highlights

Sources of Cash During the Six Months Ended June 30, 2023:

•We borrowed (and fully repaid) $150 million of loans under our revolving credit facility, which were used as a short term liquidity bridge5 to fund the repurchase of our outstanding non-voting convertible ordinary shares during the first quarter of 2023;

•We received cash, restricted cash and cash equivalents from the QBE and RACQ transactions of $402 million; and

•We received $94 million as consideration for the novation of the Enhanzed Re reinsurance closed block of life annuity policies.

Uses of Cash During the Six Months Ended June 30, 2023:

•We repurchased 1,597,712 of our outstanding non-voting convertible ordinary shares for an aggregate price of $341 million;

•We repurchased the entire 24.9% ownership interest Allianz held in Enhanzed Re for $175 million; and

•We paid $18 million of cash dividends on our Series D and E Preferred Shares.

As of June 30, 2023 we had $768 million of cash and cash equivalents, excluding restricted cash, that supports (re)insurance operations. Included in this amount was $316 million held by our foreign subsidiaries outside of Bermuda. We closed 2022 with a solvency capital ratio of 210%, and we believe that we have sufficient liquidity and capital resources to meet our business requirements for the next 12 months and thereafter.

5 The drawdown was fully repaid once proceeds from the sale of fixed maturities, trading and equities was received.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 53

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

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 Subordinated Notes) not exceeding 15% of total capital attributable to Enstar. As of June 30, 2023, we were in compliance with the financial covenants in our credit facilities.

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 also utilize credit loan facilities, and we have issued senior notes and preferred shares and guaranteed our Junior Subordinated Notes.

In May 2023, we and certain of our subsidiaries, as borrowers and guarantors, amended and restated our existing revolving credit agreement, which we entered in August 2018. The amendment increased the total commitments under the revolving credit facility from $600 million to $800 million and extended the expiry date to May 30, 2028. We have the option to request additional commitments under the facility by up to an aggregate amount of $200 million, which the existing lenders, in their discretion, or new lenders, may provide. Under the amended facility, we may borrow revolving loans or request the issuance of syndicated or fronted letters of credit, in each case on a senior, unsecured basis, and pricing will continue to be based on a per annum rate comprising a reference rate determined based on the type of loan we borrow plus a margin based on our long term senior unsecured debt ratings. As of June 30, 2023, we had $800 million of available unutilized capacity under this unsecured revolving credit agreement.

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.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 54

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

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 June 30, 2023 for any material withholding taxes on dividends or other distributions.

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.

Operating Company Liquidity

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 June 30, 2023, all of our (re)insurance subsidiaries’ capital requirement levels were in excess of the minimum levels required.

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.

Sources and Uses of Cash

Cash and cash equivalents decreased by $144 million for the six months ended June 30, 2023, which was largely due to cash used in financing and investing activities of $533 million and $31 million, respectively, partially offset by cash provided by operating activities of $437 million.

Cash and cash equivalents decreased by $1.0 billion for the six months ended June 30, 2022, which was largely due to cash used in operating and investing activities of $117 million and $934 million, respectively, partially offset by cash provided by financing activities of $33 million.

Analysis of Sources and Uses of Cash

Operating Cash Flow Activities

2023 vs 2022: Cash provided by operating activities of $437 million for the six months ended June 30, 2023 was driven by net sales and maturities of trading securities of $591 million and cash from other sources of $297 million, which was primarily generated by the release of funds held balances to cover net paid claims on certain portfolios, partially offset by the payment of general and administrative and interest expenses. We also received $402 million of cash as partial consideration for the QBE and RACQ LPTs, $242 million from receipt of net investment income and $94 million for the Enhanzed Re gain on novation. Partially offsetting these cash inflows was net paid losses of $1.2 billion. In comparison, cash used in operating activities of $117 million for the six months ended June 30, 2022 was driven by net paid losses of $828 million, partially offset by net sales and maturities of trading securities of $772 million and net investment income received of $199 million.

Investing Cash Flow Activities

2023 vs 2022: Cash used in investing activities of $31 million for the six months ended June 30, 2023 was primarily due to net purchases of fixed maturities, AFS and other investments of $7 million and $25 million, respectively. In

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 56

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

comparison, cash used in investing activities of $934 million for the six months ended June 30, 2022 was primarily due to net purchases of fixed maturities, AFS and other investments of $34 million and $902 million, respectively.

Financing Cash Flow Activities

2023 vs 2022: Cash used in financing activities of $533 million for the six months ended June 30, 2023 was primarily 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, in addition to Enhanzed Re’s repurchase of the entire 24.9% ownership interest Allianz held in Enhanzed Re for $175 million. In comparison, cash provided by financing activities of $33 million for the six months ended June 30, 2022 was largely driven by net proceeds from loans of $214 million, partially offset by share repurchases of $163 million.

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 June 30, 2023 and December 31, 2022 were as follows:

Facility	Origination Date	Term	June 30, 2023		December 31, 2022
			(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	495		495
Total Senior Notes			991		991
5.75% Junior Subordinated Notes due 2040	August 2020	20 years	345		345
5.50% Junior Subordinated Notes due 2042	January 2022	20 years	494		493
Total Junior Subordinated Notes			839		838
Total debt obligations			$	1,830	$	1,829

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.

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.

The following table includes only material changes in our contractual obligations as disclosed in “Part II, Item 7” Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2022, and primarily relate to changes resulting from the QBE LPT transaction.

As of June 30, 2023, our estimated payments for losses and LAE by expected payment date for the Run-off segment was as follows:

Total estimated gross reserves for losses and LAE for the Run-off segment (1)	$	14,345	$	2,652	$	3,457	$	2,130	$	3,223	$	2,883

(1)     The reserves for losses and LAE represent management’s estimate of the ultimate cost of settling losses. The estimation of losses is based on various complex and subjective judgments. Actual losses paid may differ, perhaps significantly, from the reserve estimates reflected in our condensed consolidated financial statements. Similarly, the timing of payment of our estimated losses is not fixed and there may be significant changes in actual payment activity. The assumptions used in estimating the likely payments due by period are based on our historical claims payment experience and industry payment patterns, but due to the inherent uncertainty in the process of estimating the timing of such payments, there is a risk that the amounts paid in any such period can be significantly different from the amounts disclosed above. The amounts in the above table represent our estimates of known liabilities as of June 30, 2023 and do not take into account corresponding reinsurance recoverable amounts that would be due to us. Furthermore, certain of the reserves included in the condensed consolidated financial statements as of June 30, 2023 were acquired by us and initially recorded at fair value with subsequent amortization, whereas the expected payments by period in the table above are the estimated payments at a future time and do not reflect the fair value adjustment in the amount payable.

Reserves for Losses and LAE

We generally attempt to match the duration of our investment portfolio to the duration of our general liability profile. We 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 as of June 30, 2023 and December 31, 2022, the weighted average durations of our Run-off segment gross reserves for losses and LAE were 4.58 years and 4.65 years, respectively. The decrease from 2022 was driven by shorter average payouts from new acquisitions during the six months ended June 30, 2023.

Item 3 | Quantitative and Qualitative Disclosures About Market Risk

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. For details on our share repurchase programs and strategic share repurchases, refer to Note 14 to our condensed consolidated financial statements. 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 June 30, 2023, we have entered into certain investment commitments and parental guarantees7. We also utilize unsecured and secured letters of credit8 and a deposit facility. We do not believe it is reasonably likely that these arrangements will have a material current or future effect on our financial condition, changes in financial condition, revenues and expenses, results of operations, liquidity, cash requirements or capital resources.

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

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 capital release solutions through its network of group companies. 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, 2022.

Our results for the second quarter 2023 included two out of period adjustments that reduced income related to the correction of errors originating in prior periods. The first adjustment related to a $21 million reduction of income for a fourth quarter 2022 fair value adjustment to liabilities accounted for under the fair value option that should have been reflected in other comprehensive income. The second quarter 2023 expense was offset by a corresponding other comprehensive income adjustment and therefore there was no impact on total comprehensive income or equity. The second adjustment related to a reduction of income of $8 million for our equity method investment in Monument Re that should have been reflected in the first quarter 2023. Management concluded that while the adjustments were significant to our second quarter 2023 due to the near break-even nature of our results for the period, they were not material to the 2023 year to date or expected full year results.

New Accounting Standards Adopted in 2023

ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12 and subsequently issued ASUs 2019-09 and 2020-11 serving to defer the effective date of implementation. These updates:

•Require at least annual review of assumptions used to determine the provision for future policyholder benefits with the recognition of any resulting re-measurement gains or losses, excluding those related to discount rate changes, in the consolidated statement of earnings;

•Use upper-medium grade fixed-income instrument rates to discount future cash flows with the impact of these changes recognized in other comprehensive income; and

•Introduce new disclosure requirements around the provisions for future policyholder benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs (“DAC”), which includes information about significant inputs, judgments, assumptions and methods used in measurement.

These amendments are effective for interim and annual reporting periods beginning after December 15, 2022.

We adopted ASU 2018-12 on January 1, 2023 using the modified retrospective transition approach, with a transition date of September 1, 2021. This is the date that we acquired Enhanzed Re through a step acquisition and consolidated Enhanzed Re’s existing assets and liabilities, including all of our future policyholder benefit contracts. Prior to the acquisition of Enhanzed Re, we did not hold any long-duration insurance liabilities.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 69

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 2. Significant New Business

We recognized an increase to AOCI of $363 million to account for the impact of remeasuring our future policyholder benefits from September 1, 2021 to December 31, 2022. This measurement adjustment had the effect of reducing our long-duration insurance liabilities and was primarily driven by a change in the discount rates during 2022.

The adoption of this standard did not have a material impact on our shareholders’ equity as of the September 1, 2021 transition date, and the period between the transition date through to December 31, 2021.

Refer to Note 8 for the expanded future policyholder benefit disclosures required upon adoption of ASU 2018-12.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 3. Segment Information

2. SIGNIFICANT NEW BUSINESS

We define new business as material transactions, which generally take the form of reinsurance or direct business transfers, or business acquisitions.

The table below sets forth a summary of new business that we have completed between January 1, 2023 and June 30, 2023:

Transaction	Consideration Received		Net Loss Reserves Assumed		DCA (1)		Type of Transaction	Remaining Limit upon Acquisition		Line of Business	Jurisdiction
	(in millions of U.S. dollars)
QBE (2)	$	1,857	$	2,036	$	179	LPT	$	838	Diversified mix of financial lines, casualty, multiline and discontinued business	North America and International
RACQ (3)	179		179		—		LPT	195		Motor vehicle Compulsory Third Party (“CTP”) liabilities	Australia
Total 2023	$	2,036	$	2,215	$	179

(1) Where the estimated ultimate losses payable exceed the consideration received at the inception of the agreement, a deferred charge asset (“DCA”) is recorded. Refer to Note 6 for additional information.

(2) Total consideration received is comprised of $1,539 million of funds held - directly managed and $344 million of restricted cash, net of consideration payable of $25 million.

(3) Total consideration received is comprised of $58 million of restricted cash, $113 million of investments and $8 million of funds held by reinsured companies.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 71

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 3. Segment Information

3. SEGMENT INFORMATION

Our segment structure is aligned with how our chief operating decision maker ("CODM"), who was determined to be our Chief Executive Officer, views our business, assesses performance and allocates resources to our business components. Our business is organized into four reportable segments: (i) Run-off; (ii) Assumed Life; (iii) Investments; and (iv) Legacy Underwriting. 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.

The Assumed Life segment previously included Enhanzed Re 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 SE (“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. We may leverage this segment for any future potential assumed life business transactions if and when they occur.

The Legacy Underwriting segment comprises SGL No.1's 25% gross share of the 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 (the “Exchange Transaction”). There is no net retention for Enstar on Atrium's 2020 and prior underwriting years. The contractual arrangements between SGL No. 1, Arden and Atrium relating to the reinsurance agreements and the Capacity Lease Agreement were settled in the second quarter of 2023. Other than the settlement of these amounts, we do not expect to record any transactions 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 all of our four 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 that are directly attributable to our reportable segments.

As of June 30, 2023 and December 31, 2022, the number of securities classified as AFS in an unrealized loss position for which an allowance for credit loss is not recorded was 2,916 and 2,935, respectively. Of these securities, the number of securities that had been in an unrealized loss position for twelve months or longer was 1,845 and 1,155, 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) Is clearly and closely related to the host contract.

The $629 million increase in funds held - directly managed from December 31, 2022 to June 30, 2023 was primarily driven by an LPT transaction with QBE completed during the second quarter of 2023, partially offset by the derecognition of the assets supporting the Enhanzed Re reinsurance of a closed block of life annuity policies that were novated during the first quarter of 2023.

Refer to the sections above for details of the short-term and fixed maturity investments within our funds held - directly managed portfolios.

Funds Held by Reinsured Companies

As of June 30, 2023 and December 31, 2022, we had funds held by reinsured companies of $3.1 billion and $3.6 billion, respectively.

Pursuant to the terms of the Aspen Insurance Holdings transaction entered in the second quarter 2022, in addition to earning a fixed crediting rate (“base crediting rate”) on the funds withheld, as of October 1, 2022 and through September 30, 2025 we will also receive a variable return (together, the “full crediting rate”).

The nature of the arrangement results in an embedded derivative, which 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 following table summarizes the components of our funds held by reinsured companies:

Restricted Assets

The carrying value of our restricted assets, including restricted cash of $418 million and $508 million, as of June 30, 2023 and December 31, 2022, respectively, was as follows:

(1) We managed and provided capacity for one Lloyd's syndicate as of June 30, 2023 (December 31, 2022: we managed and/or provided capacity for three Lloyd’s syndicates). 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. We also utilize unsecured letters of credit for a significant portion of our FAL.

5. DERIVATIVES AND HEDGING INSTRUMENTS

We use derivative instruments in our risk management strategies and investment operations.

Foreign currency forward exchange rate contracts are used in qualifying hedging relationships to hedge the foreign currency exchange rate risk associated with certain of our net investments in foreign operations.

We also utilize foreign currency forward contracts in non-qualifying hedging relationships as part of our overall foreign currency risk management strategy or to obtain exposure to a particular financial market, as well as for yield enhancement and collectively managing credit and duration risk.

In February 2023, we entered into a two-month forward starting receive fixed, pay floating interest rate swap 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. For the three and six months ended June 30, 2023, we recorded net realized and unrealized losses of $4 million and net realized and unrealized gains of $8 million, respectively.

From time to time, consolidated funds in which we invest may utilize credit default swaps to both hedge and replicate credit exposure and government bond futures contracts for interest rate management.

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 June 30, 2023 and December 31, 2022:

6. 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 in excess of the estimated undiscounted ultimate losses payable, a deferred gain liability (“DGL”) is recorded. In addition, for retrocessions of losses and LAE reserves that we may assume through retroactive reinsurance contracts where the retroceded liabilities exceed the retrocession consideration paid, we would record a DGL.

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

Effective December 31, 2022, we voluntarily changed our accounting policy for calculating the amortization of our DCAs1. Previously, any change in ultimate losses on the contracts with a recognized DCA would result in the recognition of an adjustment to the DCA, as if the adjusted reserves had existed upon inception of the contract. The policy modification eliminated adjustments of the DCA for these events.

We have retrospectively applied this change in accounting policy to all applicable prior period information presented herein as required.

The following table presents a summary of the DCA and DGL balances and related activity for the three and six months ended June 30, 2023 and 2022:

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 7. Losses and Loss Adjustment Expenses

7. 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.

Total	$	(8)	$	(103)	$	(23)	$	(161)

Three Months Ended June 30, 2023:

The prior period reduction in estimates of net ultimate losses of $8 million was driven by $9 million of favorable development on our Run-off segment workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Three Months Ended June 30, 2022:

The reduction in estimates of net ultimate losses of $103 million related to prior periods was primarily driven by favorable development on our Run-off segment professional indemnity/directors and officers and workers’ compensation lines of business as a result of favorable loss activity, most notably in the 2021 acquisition year.

Six Months Ended June 30, 2023:

The prior period reduction in estimates of net ultimate losses of $23 million was driven by $20 million of favorable development on our Run-off segment workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Six Months Ended June 30, 2022:

The reduction in estimates of net ultimate losses of $161 million related to prior periods was primarily driven by the Run-off and Assumed Life segments.

The Run-off segment experienced favorable PPD of $137 million, which was primarily driven by favorable loss activity in the professional indemnity/directors and officers and workers’ compensation lines of business.

The Assumed Life segment experienced favorable PPD of $29 million primarily due to favorable claim activity on our 2021 acquisition year property excess of loss (catastrophe) business.

Item 1 | Notes to Consolidated Financial Statements | Note 8. Future Policyholder Benefits

Reduction in Provisions for ULAE

Three and Six Months Ended June 30, 2023

The reduction in provisions for ULAE was adversely impacted by an increase of $21 million for the three and six months ended June 30, 2023, respectively, as a result of assuming active claims control on a 2022 LPT agreement with Argo, which fully offset and partially offset other ULAE provision adjustments from our run-off operations for those same periods, respectively.

Three and Six Months Ended June 30, 2022

The favorable reduction in provisions for ULAE for the three and six months ended June 30, 2022 was driven by ULAE provision adjustments from our run-off operations.

Changes in Fair Value - Fair Value Option

Three Months Ended June 30, 2023 and 2022:

PPD was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $8 million and $48 million for the three months ended June 30, 2023 and 2022, respectively, which was primarily driven by increases in corporate bond yields, which is a component of the discount rate used to calculate the fair value of the liabilities, during both periods. The favorable results for the three months ended June 30, 2023 were adversely impacted by the $21 million adjustment to reclassify the portion of the change in fair value related to the Enstar-specific credit risk from net incurred losses and LAE to AOCI.

Six Months Ended June 30, 2023 and 2022:

PPD was adversely impacted by changes in the fair value of liabilities for which we have elected the fair value option of $12 million for the six months ended June 30, 2023, which was primarily a result of a net decrease in corporate bond yields during the first half of 2023 and the impact of the $21 million adjustment to reclassify the portion of the change in fair value related to the Enstar-specific credit risk from net incurred losses and LAE to AOCI. For the comparative period, PPD was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $146 million due to an increase in corporate bond yields.

Item 1 | Notes to Consolidated Financial Statements | Note 8. Future Policyholder Benefits

8. 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.

We adopted ASU 2018-12 effective January 1, 2023 using the modified retrospective transition approach, with a transition date of September 1, 2021. This is the date that we acquired Enhanzed Re through a step acquisition and consolidated Enhanzed Re’s existing assets and liabilities, including all of our future policyholder benefit contracts. The effects of the adoption as of the transition date and through December 31, 2021 were not material, primarily due to the overall consistency of the interest rate assumption that was previously established based on investment yields (net of related investment expenses) expected as of September 1, 2021 compared to the upper-medium grade fixed-income instrument yield, as applied under ASU 2018-12, as of the same dates.

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 June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(in millions of U.S. dollars)
Beginning Balance (1)	$	—	$	1,391	$	821	$	1,502
Interest accretion and other policyholder benefit expenses	—		6		—		18
Benefits paid	—		(15)		(6)		(30)
Recapture of assumed liabilities by ceding company	—		—		—		(34)
Terminations (surrenders)	—		(7)		—		(10)
Effect of exchange rate movement	—		(41)		13		(67)
Derecognition (2)	—		—		(828)		—
Effect of changes in discount rate	—		(135)		—		(180)
Other	—		(16)		—		(16)
Balance as of June 30	—		1,183		—		1,183

(1) The liability for future policyholder benefits as of January 1, 2023 and January 1, 2022 has been adjusted by $363 million and $0, respectively, for the impact of adopting ASU 2018-12 due to the effect of remeasuring the liabilities using an upper medium grade fixed-income instrument yield. The January 1, 2023 adjustment was reflected through an increase in other comprehensive income of $363 million due to changes in the discount rate during 2022, of which $90 million was attributable to NCI. There was no adjustment to the January 1, 2022 amount given the proximity of the acquisition of a controlling interest in Enhanzed Re on September 1, 2021, in which we recorded the liabilities at fair value in accordance with purchase accounting requirements. The corresponding balance as of September 30, 2021 would be the amount recorded as of December 31, 2021 given our one quarter reporting lag for Enhanzed Re. Furthermore, interest rate movements in this one month period were inconsequential.

(2) 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.

For the three and six months ended June 30, 2022, we recognized $1 million and $15 million of gross premiums, respectively. There were no gross premiums recognized for the three and six months ended June 30, 2023.

As required by the adoption of ASU 2018-12, discount rate assumptions associated with liability remeasurement are updated at each reporting period to reflect the current upper-medium grade fixed-income instrument yield, with changes in the interest rate from inception to current period reported through accumulated other comprehensive loss.

We have designed a discount rate methodology to incorporate the currency and duration characteristics of the liabilities. For interest accretion, interest rates are fixed at inception. Significant assumptions to the calculation of future policyholder benefits also include mortality, mortality improvement, and timing of cash flow payments. The assumptions are reviewed at least annually. During 2022, we undertook a review of all significant assumptions and did not make any changes to the mortality improvement, mortality improvement, or timing of cash flow payments as

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 88

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 9. Defendant Asbestos and Environmental Liabilities

actual experience was materially consistent with established assumptions for the same date. Accordingly, there was no effect of changes in the liability relating to changes in cash flow assumptions. In addition, the effects of actual variances from expected policyholder behavior experience were not material for the three and six month periods ended June 30, 2023 and 2022.

The undiscounted expected future net benefit payments as of June 30, 2022 were $1.5 billion. The weighted-average duration of the liability, interest accretion rate and interest rate for discounting the liability for future policyholder benefits as of June 30, 2022 was 11.8 years, 0.7% and 1.9%, respectively.

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 earnings attributable to Enstar were 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 preexisting 20% ownership interest in Monument Re.

The following table illustrates the calculation of the gain on novation for the six months ended June 30, 2023:

	Six Months Ended June 30, 2023
	(in millions of U.S. dollars)
Calculation of carrying value as of transaction closing:

10. 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 condensed consolidated financial statements.

Enstar Group Limited | Second Quarter 2023 | Form 10-Q                 96

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 11. Variable Interest Entities

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		June 30, 2023	December 31, 2022
	Unobservable (U) and Observable (O) Inputs	Weighted Average
Internal model	Corporate bond yield (O)	A Rated	A Rated
Internal model	Credit spread for Enstar-specific credit risk (U)	0.65%	0.65%
Internal model	Risk cost of capital (U)	5.10%	5.10%
Internal model	Weighted average cost of capital (U)	8.25%	8.25%
Internal model	Average payout - liability (U)	8.01 years	7.89 years
Internal model	Average payout - reinsurance balances recoverable on paid and unpaid losses (U)	7.93 years	7.71 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 condensed consolidated statements of earnings. Changes in the fair value due to changes in credit spread for Enstar-specific credit risk are classified to other comprehensive income.

Disclosure of Fair Values for Financial Instruments Carried at Cost

Senior and Subordinated Notes

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

	June 30, 2023
	Amortized Cost		Fair Value
	(in millions of U.S. dollars)
4.95% Senior Notes due 2029	$	496	$	466
3.10% Senior Notes due 2031	495		392
Total Senior Notes	$	991	$	858
5.75% Junior Subordinated Notes due 2040	$	345	$	304
5.50% Junior Subordinated Notes due 2042	494		373
Total Subordinated Notes	$	839	$	677

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

Both the Senior and 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 June 30, 2023 and December 31, 2022.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 12. Debt Obligations

11. 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 have elected to recognize the results of the GCM Fund on a one quarter lag due to anticipated delays in obtaining timely financial information. As of June 30, 2023, $60 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 June 30, 2023. Net investment income, changes in the fair value of assets and liabilities of the GCM Fund and management fees will be presented within existing captions in the consolidated statements of earnings.

We recognized $2 million of unrealized gains on other investments for the three and six months ended June 30, 2023. All other amounts were immaterial for the three and six months ended June 30, 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:

12. DEBT OBLIGATIONS

Revolving Credit Facility

In May 2023, we and certain of our subsidiaries, as borrowers and guarantors, amended and restated our existing revolving credit agreement. The amendment increased the total commitments under the revolving credit facility from $600 million to $800 million and extended the expiry date to May 30, 2028. We may request additional commitments under the facility by up to an aggregate amount of $200 million, which the existing lenders, in their discretion, or new lenders, may provide. Under the amended facility, we may borrow revolving loans or request the issuance of syndicated or fronted letters of credit, in each case on a senior, unsecured basis.

Pricing under the facility will continue to be based on a per annum rate comprising a reference rate determined based on the type and currency of loan we borrow plus a margin that varies based on changes to our long term senior unsecured debt ratings assigned by S&P or Fitch (the “Debt Ratings”). The applicable reference rate is an adjusted forward-looking term rate based on the Secured Overnight Financing Rate (“Adjusted Term SOFR”) for loans denominated in U.S. dollars, a rate based on the Sterling Overnight Index Average for loans denominated in British pounds sterling, an adjusted rate based on the Euro Interbank Offered Rate for loans denominated in euros and a rate equal to the highest of the Prime Rate, an adjusted rate based on the Federal Funds Effective Rate and Adjusted Term SOFR (for a one-month period) for swingline loans. We pay letter of credit fees based on the average daily aggregate stated amount of outstanding letters of credit and the Debt Ratings. In addition, we pay commitment fees based on the average daily unused amount of the commitments and the Debt Ratings. If an event of default occurs, the interest rate will increase and the agent may, and at the request of the required lenders shall, terminate lender commitments and demand early repayment of any outstanding amounts borrowed (or cash collateralization of a percentage excess of the amount of outstanding letters of credit issued) under the facility.

Financial and business covenants imposed on us in relation to the amended facility include certain limitations on indebtedness and guarantees, liens, mergers, consolidations and other fundamental changes, and dispositions. Generally, the financial covenants require us to maintain a gearing ratio of consolidated financial indebtedness to total capitalization of not greater than 0.35 to 1.0 and to maintain a consolidated net worth of not less than the aggregate of (i) $4.3 billion, plus (ii) 50% of net income available for distribution to ordinary shareholders at any time after June 30, 2022 (excluding net unrealized gains or losses on investments), plus (iii) 50% of the proceeds of any issuance of ordinary shares made after June 30, 2022. In addition, we must maintain eligible capital in excess of the enhanced capital requirement imposed by the Bermuda Monetary Authority pursuant to the Insurance (Group Supervision) Rules 2011 of Bermuda. As of June 30, 2023, we are in compliance with the covenants of the EGL Revolving Credit Facility.

As of June 30, 2023, we had no borrowings outstanding and therefore had $800 million of available unutilized capacity under our unsecured revolving credit agreement.

On December 28, 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 condensed consolidated statements of changes in shareholder's equity.

15. EARNINGS PER SHARE

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

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2023		2022		2023		2022
	(in millions of U.S. dollars, except share and per share data)
Numerator:
Net earnings (loss) attributable to Enstar ordinary shareholders:	$	21	$	(434)	$	445	$	(701)
Denominator:
Weighted-average ordinary shares outstanding — basic (1)	15,460,318		17,224,449		16,216,080		17,400,257
Effect of dilutive securities:
Share-based compensation plans (2)	200,663		246,242		150,437		234,441
Weighted-average ordinary shares outstanding — diluted (3)	15,660,981		17,470,691		16,366,517		17,634,698
Earnings (loss) per share attributable to Enstar ordinary shareholders:
Basic	$	1.36	$	(25.20)	$	27.44	$	(40.29)
Diluted (3)	$	1.34	$	(25.20)	$	27.19	$	(40.29)

(1) Weighted-average ordinary shares for basic (loss) 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.

(2) Share-based dilutive securities include restricted shares, restricted share units, and performance share units. Certain share-based compensation awards were excluded from the calculation for the three and six months ended June 30, 2023 and 2022 because they were anti-dilutive. The ordinary shares held in the EB Trust in respect of JSOP awards were also excluded because they are treated as held in treasury.

(3) During a period of loss, the basic weighted-average ordinary shares outstanding is used in the denominator of the diluted loss per ordinary share computation as the effect of including potentially dilutive securities would be anti-dilutive.

Item 1 | Notes to the Unaudited Condensed Consolidated Financial Statements | Note 18. Subsequent Events

17. 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 June 30, 2023, we had funds held concentrations to reinsured companies exceeding 10% of shareholders’ equity of $5.2 billion (December 31, 2022: $5.0 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 instruments and the counterparties noted above, exceeded 10% of shareholders’ equity as of June 30, 2023. Our credit exposure to the U.S. government was $935 million as of June 30, 2023 (December 31, 2022: $945 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 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 June 30, 2023, we had unfunded commitments of $1.8 billion to other investments and $18 million to privately held equity.

Guarantees

As of June 30, 2023, parental guarantees supporting reinsurance obligations, defendant A&E liabilities, subsidiary capital support arrangements and credit facilities were $2.3 billion. We also guarantee the 2040 and 2042 Junior Subordinated Notes, which have an aggregate principal amount of $850 million as of June 30, 2023.

Redeemable Noncontrolling Interests

Since March 31, 2023, pursuant to contractual terms, we have the right to purchase the RNCI interests from the RNCI holders (each such right, a "call right") and since December 31, 2022, the RNCI holders have the right to sell their RNCI interests to us (each such right, a "put right"). Following the closing of the Exchange Transaction, we have maintained a call right over the portion of StarStone Specialty Holdings Limited owned by the Trident V Funds and Dowling Capital Partners I, L.P. and Capital City Partners LLC, and they will maintain put rights to transfer those interests to us.

Debt Obligations

Letters of Credit

On July 28 2023, we amended and restated our existing $800 million syndicated letter of credit facility agreement, pursuant to which we request the issuance of syndicated letters of credit that we use to collateralize certain reinsurance obligations. The initial commitment period under the agreement is one year, subject to our right to request up to four one-year extensions of the commitment period, for a maximum of five years.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of management, including our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of June 30, 2023. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that we maintained effective disclosure controls and procedures to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and timely reported as specified in the rules and forms of the U.S. Securities and Exchange Commission and is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Accounting Policies [Abstract]

BASIS OF PRESENTATION

1. BASIS OF PRESENTATION

Enstar Group Limited ("Enstar") is a leading global (re)insurance group that offers capital release solutions through its network of group companies. 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, 2022.

Our results for the second quarter 2023 included two out of period adjustments that reduced income related to the correction of errors originating in prior periods. The first adjustment related to a $21 million reduction of income for a fourth quarter 2022 fair value adjustment to liabilities accounted for under the fair value option that should have been reflected in other comprehensive income. The second quarter 2023 expense was offset by a corresponding other comprehensive income adjustment and therefore there was no impact on total comprehensive income or equity. The second adjustment related to a reduction of income of $8 million for our equity method investment in Monument Re that should have been reflected in the first quarter 2023. Management concluded that while the adjustments were significant to our second quarter 2023 due to the near break-even nature of our results for the period, they were not material to the 2023 year to date or expected full year results.

New Accounting Standards Adopted in 2023

ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12 and subsequently issued ASUs 2019-09 and 2020-11 serving to defer the effective date of implementation. These updates:

•Require at least annual review of assumptions used to determine the provision for future policyholder benefits with the recognition of any resulting re-measurement gains or losses, excluding those related to discount rate changes, in the consolidated statement of earnings;

•Use upper-medium grade fixed-income instrument rates to discount future cash flows with the impact of these changes recognized in other comprehensive income; and

•Introduce new disclosure requirements around the provisions for future policyholder benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs (“DAC”), which includes information about significant inputs, judgments, assumptions and methods used in measurement.

These amendments are effective for interim and annual reporting periods beginning after December 15, 2022.

We adopted ASU 2018-12 on January 1, 2023 using the modified retrospective transition approach, with a transition date of September 1, 2021. This is the date that we acquired Enhanzed Re through a step acquisition and consolidated Enhanzed Re’s existing assets and liabilities, including all of our future policyholder benefit contracts. Prior to the acquisition of Enhanzed Re, we did not hold any long-duration insurance liabilities.

We recognized an increase to AOCI of $363 million to account for the impact of remeasuring our future policyholder benefits from September 1, 2021 to December 31, 2022. This measurement adjustment had the effect of reducing our long-duration insurance liabilities and was primarily driven by a change in the discount rates during 2022.

The adoption of this standard did not have a material impact on our shareholders’ equity as of the September 1, 2021 transition date, and the period between the transition date through to December 31, 2021.

Refer to Note 8 for the expanded future policyholder benefit disclosures required upon adoption of ASU 2018-12.

Segment Reporting [Abstract]

SEGMENT INFORMATION

3. SEGMENT INFORMATION

Our segment structure is aligned with how our chief operating decision maker ("CODM"), who was determined to be our Chief Executive Officer, views our business, assesses performance and allocates resources to our business components. Our business is organized into four reportable segments: (i) Run-off; (ii) Assumed Life; (iii) Investments; and (iv) Legacy Underwriting. 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.

The Assumed Life segment previously included Enhanzed Re 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 SE (“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. We may leverage this segment for any future potential assumed life business transactions if and when they occur.

The Legacy Underwriting segment comprises SGL No.1's 25% gross share of the 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 (the “Exchange Transaction”). There is no net retention for Enstar on Atrium's 2020 and prior underwriting years. The contractual arrangements between SGL No. 1, Arden and Atrium relating to the reinsurance agreements and the Capacity Lease Agreement were settled in the second quarter of 2023. Other than the settlement of these amounts, we do not expect to record any transactions 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 all of our four 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 that are directly attributable to our reportable segments.

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

As of June 30, 2023 and December 31, 2022, the number of securities classified as AFS in an unrealized loss position for which an allowance for credit loss is not recorded was 2,916 and 2,935, respectively. Of these securities, the number of securities that had been in an unrealized loss position for twelve months or longer was 1,845 and 1,155, 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.

The $629 million increase in funds held - directly managed from December 31, 2022 to June 30, 2023 was primarily driven by an LPT transaction with QBE completed during the second quarter of 2023, partially offset by the derecognition of the assets supporting the Enhanzed Re reinsurance of a closed block of life annuity policies that were novated during the first quarter of 2023.

Refer to the sections above for details of the short-term and fixed maturity investments within our funds held - directly managed portfolios.

Funds Held by Reinsured Companies

As of June 30, 2023 and December 31, 2022, we had funds held by reinsured companies of $3.1 billion and $3.6 billion, respectively.

Pursuant to the terms of the Aspen Insurance Holdings transaction entered in the second quarter 2022, in addition to earning a fixed crediting rate (“base crediting rate”) on the funds withheld, as of October 1, 2022 and through September 30, 2025 we will also receive a variable return (together, the “full crediting rate”).

The nature of the arrangement results in an embedded derivative, which 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 following table summarizes the components of our funds held by reinsured companies:

(1) We managed and provided capacity for one Lloyd's syndicate as of June 30, 2023 (December 31, 2022: we managed and/or provided capacity for three Lloyd’s syndicates). 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. We also utilize unsecured letters of credit for a significant portion of our FAL.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES AND HEDGING INSTRUMENTS

5. DERIVATIVES AND HEDGING INSTRUMENTS

We use derivative instruments in our risk management strategies and investment operations.

Foreign currency forward exchange rate contracts are used in qualifying hedging relationships to hedge the foreign currency exchange rate risk associated with certain of our net investments in foreign operations.

We also utilize foreign currency forward contracts in non-qualifying hedging relationships as part of our overall foreign currency risk management strategy or to obtain exposure to a particular financial market, as well as for yield enhancement and collectively managing credit and duration risk.

In February 2023, we entered into a two-month forward starting receive fixed, pay floating interest rate swap 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. For the three and six months ended June 30, 2023, we recorded net realized and unrealized losses of $4 million and net realized and unrealized gains of $8 million, respectively.

From time to time, consolidated funds in which we invest may utilize credit default swaps to both hedge and replicate credit exposure and government bond futures contracts for interest rate management.

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 June 30, 2023 and December 31, 2022:

Deferred Charge Assets and Deferred Gain Liabilities

Insurance [Abstract]

DEFERRED CHARGE ASSETS AND DEFERRED GAIN LIABILITIES

6. 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 in excess of the estimated undiscounted ultimate losses payable, a deferred gain liability (“DGL”) is recorded. In addition, for retrocessions of losses and LAE reserves that we may assume through retroactive reinsurance contracts where the retroceded liabilities exceed the retrocession consideration paid, we would record a DGL.

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

Effective December 31, 2022, we voluntarily changed our accounting policy for calculating the amortization of our DCAs1. Previously, any change in ultimate losses on the contracts with a recognized DCA would result in the recognition of an adjustment to the DCA, as if the adjusted reserves had existed upon inception of the contract. The policy modification eliminated adjustments of the DCA for these events.

We have retrospectively applied this change in accounting policy to all applicable prior period information presented herein as required.

The following table presents a summary of the DCA and DGL balances and related activity for the three and six months ended June 30, 2023 and 2022:

LOSSES AND LOSS ADJUSTMENT EXPENSES

7. 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.

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

Three Months Ended June 30, 2023:

The prior period reduction in estimates of net ultimate losses of $8 million was driven by $9 million of favorable development on our Run-off segment workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Three Months Ended June 30, 2022:

The reduction in estimates of net ultimate losses of $103 million related to prior periods was primarily driven by favorable development on our Run-off segment professional indemnity/directors and officers and workers’ compensation lines of business as a result of favorable loss activity, most notably in the 2021 acquisition year.

Six Months Ended June 30, 2023:

The prior period reduction in estimates of net ultimate losses of $23 million was driven by $20 million of favorable development on our Run-off segment workers’ compensation line of business as a result of continued favorable claims experience, most notably in the 2021 acquisition year.

Six Months Ended June 30, 2022:

The reduction in estimates of net ultimate losses of $161 million related to prior periods was primarily driven by the Run-off and Assumed Life segments.

The Run-off segment experienced favorable PPD of $137 million, which was primarily driven by favorable loss activity in the professional indemnity/directors and officers and workers’ compensation lines of business.

The Assumed Life segment experienced favorable PPD of $29 million primarily due to favorable claim activity on our 2021 acquisition year property excess of loss (catastrophe) business.

Reduction in Provisions for ULAE

Three and Six Months Ended June 30, 2023

The reduction in provisions for ULAE was adversely impacted by an increase of $21 million for the three and six months ended June 30, 2023, respectively, as a result of assuming active claims control on a 2022 LPT agreement with Argo, which fully offset and partially offset other ULAE provision adjustments from our run-off operations for those same periods, respectively.

Three and Six Months Ended June 30, 2022

The favorable reduction in provisions for ULAE for the three and six months ended June 30, 2022 was driven by ULAE provision adjustments from our run-off operations.

Changes in Fair Value - Fair Value Option

Three Months Ended June 30, 2023 and 2022:

PPD was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $8 million and $48 million for the three months ended June 30, 2023 and 2022, respectively, which was primarily driven by increases in corporate bond yields, which is a component of the discount rate used to calculate the fair value of the liabilities, during both periods. The favorable results for the three months ended June 30, 2023 were adversely impacted by the $21 million adjustment to reclassify the portion of the change in fair value related to the Enstar-specific credit risk from net incurred losses and LAE to AOCI.

Six Months Ended June 30, 2023 and 2022:

PPD was adversely impacted by changes in the fair value of liabilities for which we have elected the fair value option of $12 million for the six months ended June 30, 2023, which was primarily a result of a net decrease in corporate bond yields during the first half of 2023 and the impact of the $21 million adjustment to reclassify the portion of the change in fair value related to the Enstar-specific credit risk from net incurred losses and LAE to AOCI. For the comparative period, PPD was favorably impacted by changes in the fair value of liabilities for which we have elected the fair value option of $146 million due to an increase in corporate bond yields.

Future Policyholder Benefits

6 Months Ended

Jun. 30, 2023

Insurance [Abstract]

FUTURE POLICYHOLDER BENEFITS

8. 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.

We adopted ASU 2018-12 effective January 1, 2023 using the modified retrospective transition approach, with a transition date of September 1, 2021. This is the date that we acquired Enhanzed Re through a step acquisition and consolidated Enhanzed Re’s existing assets and liabilities, including all of our future policyholder benefit contracts. The effects of the adoption as of the transition date and through December 31, 2021 were not material, primarily due to the overall consistency of the interest rate assumption that was previously established based on investment yields (net of related investment expenses) expected as of September 1, 2021 compared to the upper-medium grade fixed-income instrument yield, as applied under ASU 2018-12, as of the same dates.

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 June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(in millions of U.S. dollars)
Beginning Balance (1)	$	—	$	1,391	$	821	$	1,502
Interest accretion and other policyholder benefit expenses	—		6		—		18
Benefits paid	—		(15)		(6)		(30)
Recapture of assumed liabilities by ceding company	—		—		—		(34)
Terminations (surrenders)	—		(7)		—		(10)
Effect of exchange rate movement	—		(41)		13		(67)
Derecognition (2)	—		—		(828)		—
Effect of changes in discount rate	—		(135)		—		(180)
Other	—		(16)		—		(16)
Balance as of June 30	—		1,183		—		1,183

(1) The liability for future policyholder benefits as of January 1, 2023 and January 1, 2022 has been adjusted by $363 million and $0, respectively, for the impact of adopting ASU 2018-12 due to the effect of remeasuring the liabilities using an upper medium grade fixed-income instrument yield. The January 1, 2023 adjustment was reflected through an increase in other comprehensive income of $363 million due to changes in the discount rate during 2022, of which $90 million was attributable to NCI. There was no adjustment to the January 1, 2022 amount given the proximity of the acquisition of a controlling interest in Enhanzed Re on September 1, 2021, in which we recorded the liabilities at fair value in accordance with purchase accounting requirements. The corresponding balance as of September 30, 2021 would be the amount recorded as of December 31, 2021 given our one quarter reporting lag for Enhanzed Re. Furthermore, interest rate movements in this one month period were inconsequential.

(2) 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.

For the three and six months ended June 30, 2022, we recognized $1 million and $15 million of gross premiums, respectively. There were no gross premiums recognized for the three and six months ended June 30, 2023.

As required by the adoption of ASU 2018-12, discount rate assumptions associated with liability remeasurement are updated at each reporting period to reflect the current upper-medium grade fixed-income instrument yield, with changes in the interest rate from inception to current period reported through accumulated other comprehensive loss.

We have designed a discount rate methodology to incorporate the currency and duration characteristics of the liabilities. For interest accretion, interest rates are fixed at inception. Significant assumptions to the calculation of future policyholder benefits also include mortality, mortality improvement, and timing of cash flow payments. The assumptions are reviewed at least annually. During 2022, we undertook a review of all significant assumptions and did not make any changes to the mortality improvement, mortality improvement, or timing of cash flow payments as

actual experience was materially consistent with established assumptions for the same date. Accordingly, there was no effect of changes in the liability relating to changes in cash flow assumptions. In addition, the effects of actual variances from expected policyholder behavior experience were not material for the three and six month periods ended June 30, 2023 and 2022.

The undiscounted expected future net benefit payments as of June 30, 2022 were $1.5 billion. The weighted-average duration of the liability, interest accretion rate and interest rate for discounting the liability for future policyholder benefits as of June 30, 2022 was 11.8 years, 0.7% and 1.9%, respectively.

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 earnings attributable to Enstar were 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 preexisting 20% ownership interest in Monument Re.

The following table illustrates the calculation of the gain on novation for the six months ended June 30, 2023:

	Six Months Ended June 30, 2023
	(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	(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 earnings 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).

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

10. 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 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:

(1) Represents an adjustment to reclassify the portion of the change in fair value attributable to our Enstar-specific credit risk from net incurred losses and LAE to AOCI. See Note 1 for additional information.

(2) Represents an offset to the adjustment booked to the change in fair value (as described above), which forms a component of prior period net incurred losses and LAE, in order to neutralize the impact to the ending fair value of insurance contracts measured at fair value. See Note 1 for additional information.

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		June 30, 2023	December 31, 2022
	Unobservable (U) and Observable (O) Inputs	Weighted Average
Internal model	Corporate bond yield (O)	A Rated	A Rated
Internal model	Credit spread for Enstar-specific credit risk (U)	0.65%	0.65%
Internal model	Risk cost of capital (U)	5.10%	5.10%
Internal model	Weighted average cost of capital (U)	8.25%	8.25%
Internal model	Average payout - liability (U)	8.01 years	7.89 years
Internal model	Average payout - reinsurance balances recoverable on paid and unpaid losses (U)	7.93 years	7.71 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 condensed consolidated statements of earnings. Changes in the fair value due to changes in credit spread for Enstar-specific credit risk are classified to other comprehensive income.

Disclosure of Fair Values for Financial Instruments Carried at Cost

Senior and Subordinated Notes

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

Variable Interest Entities

6 Months Ended

Jun. 30, 2023

Organization, Consolidation and Presentation of Financial Statements [Abstract]

VARIABLE INTEREST ENTITIES

11. 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 have elected to recognize the results of the GCM Fund on a one quarter lag due to anticipated delays in obtaining timely financial information. As of June 30, 2023, $60 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 June 30, 2023. Net investment income, changes in the fair value of assets and liabilities of the GCM Fund and management fees will be presented within existing captions in the consolidated statements of earnings.

We recognized $2 million of unrealized gains on other investments for the three and six months ended June 30, 2023. All other amounts were immaterial for the three and six months ended June 30, 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:

Revolving Credit Facility

In May 2023, we and certain of our subsidiaries, as borrowers and guarantors, amended and restated our existing revolving credit agreement. The amendment increased the total commitments under the revolving credit facility from $600 million to $800 million and extended the expiry date to May 30, 2028. We may request additional commitments under the facility by up to an aggregate amount of $200 million, which the existing lenders, in their discretion, or new lenders, may provide. Under the amended facility, we may borrow revolving loans or request the issuance of syndicated or fronted letters of credit, in each case on a senior, unsecured basis.

Pricing under the facility will continue to be based on a per annum rate comprising a reference rate determined based on the type and currency of loan we borrow plus a margin that varies based on changes to our long term senior unsecured debt ratings assigned by S&P or Fitch (the “Debt Ratings”). The applicable reference rate is an adjusted forward-looking term rate based on the Secured Overnight Financing Rate (“Adjusted Term SOFR”) for loans denominated in U.S. dollars, a rate based on the Sterling Overnight Index Average for loans denominated in British pounds sterling, an adjusted rate based on the Euro Interbank Offered Rate for loans denominated in euros and a rate equal to the highest of the Prime Rate, an adjusted rate based on the Federal Funds Effective Rate and Adjusted Term SOFR (for a one-month period) for swingline loans. We pay letter of credit fees based on the average daily aggregate stated amount of outstanding letters of credit and the Debt Ratings. In addition, we pay commitment fees based on the average daily unused amount of the commitments and the Debt Ratings. If an event of default occurs, the interest rate will increase and the agent may, and at the request of the required lenders shall, terminate lender commitments and demand early repayment of any outstanding amounts borrowed (or cash collateralization of a percentage excess of the amount of outstanding letters of credit issued) under the facility.

Financial and business covenants imposed on us in relation to the amended facility include certain limitations on indebtedness and guarantees, liens, mergers, consolidations and other fundamental changes, and dispositions. Generally, the financial covenants require us to maintain a gearing ratio of consolidated financial indebtedness to total capitalization of not greater than 0.35 to 1.0 and to maintain a consolidated net worth of not less than the aggregate of (i) $4.3 billion, plus (ii) 50% of net income available for distribution to ordinary shareholders at any time after June 30, 2022 (excluding net unrealized gains or losses on investments), plus (iii) 50% of the proceeds of any issuance of ordinary shares made after June 30, 2022. In addition, we must maintain eligible capital in excess of the enhanced capital requirement imposed by the Bermuda Monetary Authority pursuant to the Insurance (Group Supervision) Rules 2011 of Bermuda. As of June 30, 2023, we are in compliance with the covenants of the EGL Revolving Credit Facility.

As of June 30, 2023, we had no borrowings outstanding and therefore had $800 million of available unutilized capacity under our unsecured revolving credit agreement.

Noncontrolling Interests

As of June 30, 2023 and December 31, 2022, we had $11 million and $186 million, respectively, of non-controlling interests (“NCI”) primarily related to external interests in two (December 31, 2022: three) of our subsidiaries.

On December 28, 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 condensed consolidated statements of changes in shareholder's equity.

Weighted-average ordinary shares outstanding — diluted (3)	15,660,981		17,470,691		16,366,517		17,634,698
Earnings (loss) per share attributable to Enstar ordinary shareholders:

Diluted (3)	$	1.34	$	(25.20)	$	27.19	$	(40.29)

(1) Weighted-average ordinary shares for basic (loss) 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.

(2) Share-based dilutive securities include restricted shares, restricted share units, and performance share units. Certain share-based compensation awards were excluded from the calculation for the three and six months ended June 30, 2023 and 2022 because they were anti-dilutive. The ordinary shares held in the EB Trust in respect of JSOP awards were also excluded because they are treated as held in treasury.

(3) During a period of loss, the basic weighted-average ordinary shares outstanding is used in the denominator of the diluted loss per ordinary share computation as the effect of including potentially dilutive securities would be anti-dilutive.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

17. 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 June 30, 2023, we had funds held concentrations to reinsured companies exceeding 10% of shareholders’ equity of $5.2 billion (December 31, 2022: $5.0 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 instruments and the counterparties noted above, exceeded 10% of shareholders’ equity as of June 30, 2023. Our credit exposure to the U.S. government was $935 million as of June 30, 2023 (December 31, 2022: $945 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 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 June 30, 2023, we had unfunded commitments of $1.8 billion to other investments and $18 million to privately held equity.

GuaranteesAs of June 30, 2023, parental guarantees supporting reinsurance obligations, defendant A&E liabilities, subsidiary capital support arrangements and credit facilities were $2.3 billion. We also guarantee the 2040 and 2042 Junior Subordinated Notes, which have an aggregate principal amount of $850 million as of June 30, 2023

Redeemable Noncontrolling Interests

Since March 31, 2023, pursuant to contractual terms, we have the right to purchase the RNCI interests from the RNCI holders (each such right, a "call right") and since December 31, 2022, the RNCI holders have the right to sell their RNCI interests to us (each such right, a "put right"). Following the closing of the Exchange Transaction, we have maintained a call right over the portion of StarStone Specialty Holdings Limited owned by the Trident V Funds and Dowling Capital Partners I, L.P. and Capital City Partners LLC, and they will maintain put rights to transfer those interests to us.

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.

New Accounting Standards Adopted in 2023

New Accounting Standards Adopted in 2023

ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12 and subsequently issued ASUs 2019-09 and 2020-11 serving to defer the effective date of implementation. These updates:

•Require at least annual review of assumptions used to determine the provision for future policyholder benefits with the recognition of any resulting re-measurement gains or losses, excluding those related to discount rate changes, in the consolidated statement of earnings;

•Use upper-medium grade fixed-income instrument rates to discount future cash flows with the impact of these changes recognized in other comprehensive income; and

•Introduce new disclosure requirements around the provisions for future policyholder benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs (“DAC”), which includes information about significant inputs, judgments, assumptions and methods used in measurement.

These amendments are effective for interim and annual reporting periods beginning after December 15, 2022.

We adopted ASU 2018-12 on January 1, 2023 using the modified retrospective transition approach, with a transition date of September 1, 2021. This is the date that we acquired Enhanzed Re through a step acquisition and consolidated Enhanzed Re’s existing assets and liabilities, including all of our future policyholder benefit contracts. Prior to the acquisition of Enhanzed Re, we did not hold any long-duration insurance liabilities.

We recognized an increase to AOCI of $363 million to account for the impact of remeasuring our future policyholder benefits from September 1, 2021 to December 31, 2022. This measurement adjustment had the effect of reducing our long-duration insurance liabilities and was primarily driven by a change in the discount rates during 2022.

The adoption of this standard did not have a material impact on our shareholders’ equity as of the September 1, 2021 transition date, and the period between the transition date through to December 31, 2021.

Refer to Note 8 for the expanded future policyholder benefit disclosures required upon adoption of ASU 2018-12.

(1) We managed and provided capacity for one Lloyd's syndicate as of June 30, 2023 (December 31, 2022: we managed and/or provided capacity for three Lloyd’s syndicates). 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. We also utilize unsecured letters of credit for a significant portion of our FAL.

	2023		2022		2023		2022

Other	—		(16)		—		(16)
Balance as of June 30	—		1,183		—		1,183

(1) The liability for future policyholder benefits as of January 1, 2023 and January 1, 2022 has been adjusted by $363 million and $0, respectively, for the impact of adopting ASU 2018-12 due to the effect of remeasuring the liabilities using an upper medium grade fixed-income instrument yield. The January 1, 2023 adjustment was reflected through an increase in other comprehensive income of $363 million due to changes in the discount rate during 2022, of which $90 million was attributable to NCI. There was no adjustment to the January 1, 2022 amount given the proximity of the acquisition of a controlling interest in Enhanzed Re on September 1, 2021, in which we recorded the liabilities at fair value in accordance with purchase accounting requirements. The corresponding balance as of September 30, 2021 would be the amount recorded as of December 31, 2021 given our one quarter reporting lag for Enhanzed Re. Furthermore, interest rate movements in this one month period were inconsequential.

(2) 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.

Schedule of Gain on Novation

The following table illustrates the calculation of the gain on novation for the six months ended June 30, 2023:

	Six Months Ended June 30, 2023
	(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	(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 earnings 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 condensed consolidated statements of earnings.

(4) Recognized in net earnings in our condensed consolidated statements of earnings.

Numerator:
Net earnings (loss) attributable to Enstar ordinary shareholders:	$	21	$	(434)	$	445	$	(701)
Denominator:
Weighted-average ordinary shares outstanding — basic (1)	15,460,318		17,224,449		16,216,080		17,400,257
Effect of dilutive securities:

Weighted-average ordinary shares outstanding — diluted (3)	15,660,981		17,470,691		16,366,517		17,634,698
Earnings (loss) per share attributable to Enstar ordinary shareholders:
Basic	$	1.36	$	(25.20)	$	27.44	$	(40.29)
Diluted (3)	$	1.34	$	(25.20)	$	27.19	$	(40.29)

(1) Weighted-average ordinary shares for basic (loss) 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.

(2) Share-based dilutive securities include restricted shares, restricted share units, and performance share units. Certain share-based compensation awards were excluded from the calculation for the three and six months ended June 30, 2023 and 2022 because they were anti-dilutive. The ordinary shares held in the EB Trust in respect of JSOP awards were also excluded because they are treated as held in treasury.

(3) During a period of loss, the basic weighted-average ordinary shares outstanding is used in the denominator of the diluted loss per ordinary share computation as the effect of including potentially dilutive securities would be anti-dilutive.
