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, 2021, 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 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;
Enhanzed Re’s life and annuity business, including the performance of assets to support the liabilities, the risk of mismatch in asset/liability duration and assumptions used to estimate reserves for future policy benefits proving to be inaccurate;
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;

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;
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;

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

Item 2 | Management's Discussion and Analysis | Operational Highlights
Operational Highlights
Our consolidated results reflect our continued progress on providing capital release solutions to our clients by acquiring and managing their run-off portfolios.
Operational highlights for the nine months ended September 30, 2022 include:
Assumed $3.2 billion of Loss Reserves from Run-off Transactions, including $3.1 billion from Aspen
On May 20, 2022 we completed a loss portfolio transfer (“LPT”) transaction with Aspen Insurance Holdings Limited (“Aspen”) with respect to $3.1 billion of net loss reserves, subject to a limit of $3.6 billion. An existing ADC between Aspen and us that closed in June 2020 was absorbed into this LPT.
As a result of this LPT transaction, we assumed an incremental $1.9 billion of net loss reserves with a diverse mix of property, liability and specialty lines of business, in exchange for incremental premium of $1.9 billion,1 and assumed claims control.
On August 31, 2022, we closed a LPT transaction with Probitas Managing Agency Limited (“Probitas”) and assumed $61 million of net loss reserves with respect to the 2018 and prior year of account exposures of Probitas’ managed Syndicate 1492 which cover general liability and financial risks underwritten worldwide. The LPT will convert into a reinsurance to close (“RITC”) effective January 1, 2023, subject to regulatory approvals.
Commenced Unwind of Enhanzed Re’s Reinsurance Transactions
On June 29, 2022, Enhanzed Re paid a $200 million dividend, of which $150 million was retained by the Company, and $50 million was paid to Allianz SE (“Allianz”) in respect of its ownership interest in Enhanzed Re. As a result of the one quarter reporting lag, the impact was reflected in our third quarter results.
Following the completion of our strategic review of Enhanzed Re earlier this year, on August 18, 2022, we entered into a Master Agreement with Allianz through which we agreed to a series of transactions2 that will allow us to unwind Enhanzed Re in an orderly manner.
Enhanzed Re completed the following transactions in the third quarter of 2022, the impact of which will be reflected in our fourth quarter results as a result of the one quarter reporting lag:
Commuted the catastrophe reinsurance business with Allianz, resulting in the recognition of a favorable commutation gain of $59 million; and
Repaid the $70 million of subordinated notes issued by Enhanzed Re to an affiliate of Allianz.
Following receipt of regulatory approval on October 31, 2022, Enhanzed Re is expected to complete a novation of the reinsurance closed block of life annuity policies to Monument Re Limited (“Monument Re”) on or about November 7, 2022. We will settle the life liabilities and the related assets at carrying value in return for cash consideration as of the closing date. As at June 30, 2022, the carrying value of these items was $1.3 billion and $1.1 billion, respectively, which we would record as $270 million of other income if measured as of this date.
Activity for the period from July 1, 2022 to the closing date will impact the amount of other income recorded.
A portion of our other income recorded will be subject to deferral to account for our 20% ownership interest in Monument Re and our net earnings attributable to Enstar will be reduced by the amount attributable to Allianz’s noncontrolling interest in Enhanzed Re. The final impact of the novation will be reflected in our first quarter 2023 results as a result of the one quarter reporting lag.
Executed Capital Transactions
We completed a $500 million junior subordinated notes offering in January 2022, the net proceeds of which were primarily used to fund the payment at maturity of the outstanding $280 million aggregate principal amount of our senior notes, which matured in March 2022.

Overall Results
Three Months Ended September 30, 2022 versus 2021:
Net loss attributable to Enstar ordinary shareholders for the three months ended September 30, 2022 was $444 million, an increase from the comparative quarter of $248 million as a result of:
An increase in our negative total investment return of $291 million, consisting of the aggregate net investment income, net realized and unrealized losses and losses from equity method investments, primarily driven by an increase in net realized and unrealized losses on our fixed maturity securities of $331 million as a result of rising interest rates and widening credit spreads. This was partially offset by a decrease in net realized and unrealized losses on our other investments, including equities, of $23 million, and an increase in net investment income of $23 million primarily due to an increase in average aggregate fixed income assets and reinvestment at higher yields.
Absence of the comparative quarter net gain on purchase and sales of subsidiaries of $47 million, driven by the bargain purchase gain recognized on the step acquisition of Enhanzed Re.
Lower net premiums earned of $48 million, partially due to placing our Starstone International business into run-off in mid-2020.
This was partially offset by:
Reduced total expenses of $109 million as a result of the combination of:
Reductions of $29 million in current period net incurred losses and LAE and $11 million in acquisition costs as a result of largely exiting or placing into run-off our active underwriting platforms, including StarStone International;
An increase in favorable prior period development in net incurred losses and LAE of $40 million driven by a reduction in the fair value of liabilities for which we have elected the fair value option; in addition to
A reduction of $26 million in general and administrative expenses primarily driven by reductions to long-term incentive plan costs.
The above resulted in a $290 million increase in our net loss to $478 million for the three months ended September 30, 2022.
Comprehensive loss attributable to Enstar increased by $395 million due to the $290 million increase in net loss and a $153 million increase in other comprehensive loss, which was primarily due to an increase in unrealized losses on our fixed income available-for-sale investments as a result of rising interest rates.
As a result of the current quarter net loss and comprehensive loss attributable to Enstar as noted above, our ROE decreased by 7.7 pp.
Nine Months Ended September 30, 2022 versus 2021:
Net loss attributable to Enstar ordinary shareholders was $1.2 billion for the nine months ended September 30, 2022, an unfavorable movement of $1.6 billion from the comparative period, as a result of:
Total negative investment return of $1.3 billion compared to total investment return of $443 million, primarily driven by an increase in net realized and unrealized losses on our fixed maturity securities of $978 million, and net realized and unrealized losses on our other investments, including equities, of $468 million for the nine months ended September 30, 2022, compared to net gains of $294 million for the comparative period. A decrease of $89 million in earnings from equity method investments further contributed to the decrease in our TIR, as a result of consolidating Enhanzed Re effective September 1, 2021. This was partially offset by an increase in net investment income of $71 million due to higher yielding investments.
Rising interest rates and widening credit spreads led to the net losses on our fixed income securities, and global equity market declines and widening high yield credit spreads led to the net losses on our other investments, including equities. These factors contributed to an annualized TIR of (8.7)% for the nine months ended September 30, 2022, in comparison to an annualized TIR of 2.8% for the comparative period.
An absence of the prior period net gain on purchase and sales of subsidiaries of $62 million, primarily driven by the bargain purchase gain recognized on the step acquisition of Enhanzed Re and a net gain on sales of subsidiaries of $15 million.

Item 2 | Management's Discussion and Analysis | Consolidated Results of Operations
Lower net earned premiums of $152 million, partially due to placing our Starstone International business into run-off in mid-2020.
This was partially offset by:
Reduced total expenses of $286 million as a result of the combination of:
Reductions of $107 million in current period net incurred losses and LAE and $30 million in acquisition costs as a result of largely exiting or placing into run-off our active underwriting platforms, including StarStone International;
An increase in favorable development in net incurred losses and LAE of $142 million, which improved our annualized RLE to 3.8% for the nine months ended September 30, 2022 in comparison to annualized RLE of 2.5% for the comparative period; in addition to
A reduction of $34 million in general and administrative expenses primarily driven by reductions to long-term incentive plan costs and a decrease in IT costs as a result of reduced project activity, partially offset by the absence of a proportional reduction in accrued performance-based costs which were recorded in the comparative period.
The above resulted in the $1.7 billion variance in our current year-to-date net loss of $1.3 billion compared to prior period net earnings of $405 million.
Comprehensive loss attributable to Enstar moved unfavorably by $2.2 billion, from income of $315 million for the nine months ended September 30, 2021 to a loss of $1.8 billion for the nine months ended September 30, 2022, primarily due to the $1.7 billion year-over-year net loss as compared to net earnings variance and a $591 million increase in other comprehensive loss, which was primarily due to an increase in unrealized losses on our fixed income available-for-sale investments as a result of rising interest rates.
BVPS decreased by 34.1% primarily as a result of comprehensive loss attributable to Enstar of $1.8 billion.
As a result of the current period net loss and comprehensive loss attributable to Enstar as noted above, our ROE decreased by 27.7 pp.

Three and Nine Months Ended September 30, 2022 versus 2021: ROE decreased by 7.7 and 27.7 pp for the three and nine months ended September 30, 2022, respectively, primarily due to:
i.an increase in net realized and unrealized losses on fixed maturity securities, which contributed 8.7 and 17.8 pp to the total reduction in ROE for the three and nine months ended September 30, 2022, respectively;
ii.net realized and unrealized losses on other investments, including equities, for the three and nine months ended September 30, 2022 compared to net losses and net gains for the equivalent periods ended September 30, 2021, respectively. This contributed 1.1 and 13.1 pp to the total reduction in ROE for the three and nine months ended September 30, 2022, respectively; and
iii.a reduction in earnings from equity method investments, which contributed 1.4 pp to the total reduction in ROE for the nine months ended September 30, 2022.
These negative factors were partially offset by:
iv. higher favorable PPD, which offset the reduction in ROE by 1.6 and 2.9 pp for the three and nine months ended September 30, 2022, respectively; and

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 discussion, we have grouped 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 (losses) gains and (losses) earnings from equity method investments.
General and administrative results: includes general and administrative expenses.
Underwriting Results
Our strategy is focused on effectively managing 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.

Current Period - Three and Nine Months Ended September 30, 2022 and 2021
The current period underwriting results from our (re)insurance operations include net earned premiums that have been declining as we transition away from active underwriting activities.
The below charts are in millions of U.S. dollars.
https://cdn.kscope.io/1b65053070d3a9ee2dbf1634065849ab-esgr-20220930_g4.jpg https://cdn.kscope.io/1b65053070d3a9ee2dbf1634065849ab-esgr-20220930_g5.jpg
The reductions in net premiums earned and current period net incurred losses and LAE were driven by reduced levels of activity arising from our exit of our active underwriting platforms beginning in 2020.
We continue to earn premium from our StarStone International business and from our Assumed Life segment. In comparison, our 2021 earned premium was primarily driven by StarStone International and AmTrust RITC business, which was entered into in 2019.
Prior Periods - RLE - Three Months Ended September 30, 2022 and 2021
The following tables summarize RLE % and Adjusted RLE %* by acquisition year, which management believes is useful in measuring and monitoring performance of our claims management activity on the portfolios that we have acquired. This permits comparability between acquisition years of different loss reserve volumes.

Item 2 | Management's Discussion and Analysis | Consolidated Results of Operations
Three Months Ended September 30, 2022:
Our Annualized RLE % was positively impacted by a reduction of $82 million in the fair value of liabilities for which we have elected the fair value option and a net reduction in estimates of net ultimate losses of $48 million, partially offset by $32 million of amortization of DCAs.
Favorable PPD in the 2017 and 2018 acquisition years was driven predominantly by a reduction in the fair value of liabilities for which we have elected the fair value option.
Favorable development as a result of lower claim activity on our marine, aviation, and transit line of business and favorable claim settlements on our workers’ compensation line of business had a favorable impact on PPD in acquisition year 2019.
Whilst acquisition year 2018 also benefited from the favorable development on our marine, aviation and transit and workers’ compensation lines of business, there was an increase in estimates of net ultimate losses as a result of worse than expected claims experience and adverse development on claims in relation to our general casualty and motor lines of business, which also impacted acquisition year 2020.
Acquisition year 2021 PPD benefited from favorable claim settlements on our workers’ compensation line of business but was adversely impacted by worse than expected claims experience on our general casualty line of business and accelerated amortization of DCAs (offsetting favorable development pursuant to our accounting policies).
Our Annualized Adjusted RLE %*, which excludes fair value adjustments, the reduction in provisions for ULAE and the changes in the loss liabilities of the Assumed Life and Legacy Underwriting segments, was positively impacted by the net reduction in estimates of net ultimate losses relating to the Run-off segment, partially offset by amortization of DCAs, as described above.

Three Months Ended September 30, 2021:
Our Annualized RLE % was positively impacted by a net reduction in estimates of net ultimate losses of $74 million, partially offset by $24 million of amortization of DCAs.
Acquisition years 2011, 2015 and 2021 benefited from better than expected claims experience and favorable results from actuarial loss reserve reviews relating to our workers’ compensation line of business.
Favorable results from actuarial loss reserve studies with respect to our property line of business had a favorable impact on acquisition years 2014 and 2019.
Acquisition years 2015 and 2019 also benefited from better than expected claims experience on our construction defect line of business.
Acquisition year 2018 benefited from the favorable development on our workers’ compensation and property lines of business, in addition to better than expected claims experience on our marine, aviation and transit line of business, but was adversely impacted by worse than expected claims experience across multiple lines of business.

The favorable movements were partially offset by accelerated amortization of DCAs relating to the 2021 acquisition year.

Nine Months Ended September 30, 2022:
Our Annualized RLE % was positively impacted by a reduction of $228 million in the fair value of liabilities for which we have elected the fair value option and a net reduction in estimates of net ultimate losses of $209 million, partially offset by $145 million of amortization of DCAs.
Favorable PPD in the 2017 and 2018 acquisition years was driven predominantly by a reduction in the fair value of liabilities for which we have elected the fair value option.
Acquisition year 2020 was adversely impacted by worse than expected claims experience and adverse development on claims in relation to our general casualty and motor lines of business.
Acquisition year 2021 PPD benefited from favorable claim settlements on our workers’ compensation and professional indemnity/directors and officers lines of business and favorable claim activity on the catastrophe book in the Assumed Life segment, which more than offset the adverse impact of worse than expected claims experience on our general casualty line of business and accelerated amortization of DCAs (offsetting favorable development pursuant to our accounting policies).
Our Annualized Adjusted RLE %* was positively impacted by the net reduction in estimates of net ultimate losses relating to the Run-off segment, partially offset by amortization of DCA, as described above.
