NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2013 and December 31, 2012

(Tabular information expressed in thousands of U.S. dollars except share and per share data)

(unaudited)

Basis of Preparation and Consolidation

The Company’s condensed consolidated financial statements have not been audited. These statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, these financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position and results of operations as at the end of and for the periods presented. Results of operations for subsidiaries acquired are included from the dates of their acquisition by the Company. The results of operations for any interim period are not necessarily indicative of the results for a full year. Inter-company accounts and transactions have been eliminated. In these notes, the terms “we,” “us,” “our,” or “the Company” refer to Enstar Group Limited and its direct and indirect subsidiaries. The following information should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Certain reclassifications have been made to the prior period reported amounts of net premiums earned—life and annuities, life and annuity policy benefits and losses and loss adjustment expenses to conform to the current period presentation. These reclassifications had no impact on income or net earnings previously reported.

Significant New Accounting Policies

As a result of the acquisitions of SeaBright Holdings, Inc. (“SeaBright”), five companies from a subsidiary of HSBC Holdings plc (the “Pavonia companies”), and Arden Reinsurance Company Limited (“Arden”), each described in Note 2—“Acquisitions”, the Company has adopted certain new significant accounting policies during the nine months ended September 30, 2013. Other than the policies described below, there have been no material changes to the Company’s significant accounting policies from those described in Note 2 to the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

(a) Premium revenue recognition

Non-life run-off

Premiums written are earned on a pro-rata basis over the period the coverage is provided. Reinsurance premiums are recorded at the inception of the policy, unless policy language stipulates otherwise, and are estimated based upon information in underlying contracts and information provided by clients and/or brokers. Changes in reinsurance premium estimates are expected and may result in significant adjustments in future periods. These estimates change over time as additional information regarding changes in underlying exposures is obtained. Any subsequent differences arising on such estimates are recorded as premiums written in the period they are determined.

Unearned premiums represent the portion of premiums written that relate to the unexpired terms of policies in force. Premiums ceded are similarly pro-rated over the period the coverage is provided with the unearned portion being deferred as prepaid reinsurance premiums.

Certain contracts that the Company has written are retrospectively rated and additional premium will be due should losses exceed pre-determined, contractual thresholds. These required additional premiums are based upon

CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

contractual terms and management judgment is involved with respect to the estimate of the amount of losses that the Company expects to be ceded. Additional premiums are recognized at the time loss thresholds specified in the contract are exceeded and are earned over the coverage period, or are earned immediately if the period of risk coverage has passed. Changes in estimates of losses recorded on contracts with additional premium features will result in changes in additional premiums based on contractual terms.

Life and annuities

The Pavonia companies, prior to going into run-off, wrote various U.S. and Canadian life insurance, including credit life and disability insurance, term life insurance, assumed life reinsurance and annuities. The Pavonia companies will continue to recognize premiums on term life insurance, assumed life reinsurance and credit life and disability insurance.

Premiums from term life insurance, credit life and disability insurance and assumed life reinsurance are generally recognized as revenue when due from policyholders. Term life, assumed life reinsurance and credit life and disability policies include those contracts with fixed and guaranteed premiums and benefits. Benefits and expenses are matched with such revenue to result in the recognition of profit over the life of the contracts.

(b) Premiums Receivable

Non-life run-off

Premiums receivable represent amounts currently due and amounts not yet due on insurance and reinsurance policies. Premiums for insurance policies are generally due at inception. Premiums for reinsurance policies generally become due over the period of coverage based on the policy terms. The Company monitors the credit risk associated with premiums receivable, taking into consideration that credit risk is reduced by the Company’s contractual right to offset loss obligations or unearned premiums against premiums receivable. Amounts deemed uncollectible are charged to net earnings in the period they are determined. Changes in the estimate of premiums written will result in an adjustment to premiums receivable in the period they are determined. Certain contracts are retrospectively rated and provide for a final adjustment to the premium based on the final settlement of all losses. Premiums receivable on such contracts are adjusted based on the estimate of losses the Company expects to incur, and are not considered due until all losses are settled.

(c) Life and annuity benefits

The Company’s life and annuity benefit and claim reserves are calculated using standard actuarial techniques and cash flow models in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 944, Financial Services—Insurance. The Company establishes and maintains its life and annuity reserves at a level that the Company estimates will, when taken together with future premium payments and investment income expected to be earned on associated premiums, be sufficient to support all future cash flow benefit obligations and third party servicing obligations as they become payable. The Company reviews its life and annuity reserves regularly and performs loss recognition testing based upon cash flow projections.

Since the development of the life and annuity reserves is based upon cash flow projection models, the Company must make estimates and assumptions based on experience and industry mortality tables, longevity and morbidity rates, lapse rates, expenses and investment experience, including a provision for adverse deviation.

NOTES TO THE UNAUDITED CONDENSED

CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The assumptions used to determine policy benefit reserves are determined at the inception of the contracts, reviewed and adjusted at the point of acquisition as required, and are locked-in throughout the life of the contract unless a premium deficiency develops. The assumptions are reviewed no less than annually and are unlocked if they would result in a material adverse reserve change. The Company establishes these estimates based upon transaction-specific historical experience, information provided by the ceding company for the assumed business and industry experience. Actual results could differ materially from these estimates. As the experience on the contracts emerges, the assumptions are reviewed by management. The Company determines whether actual and anticipated experience indicates that existing policy reserves, together with the present value of future gross premiums, are sufficient to cover the present value of future benefits, settlement and maintenance costs and to recover unamortized acquisition costs. If such a review indicates that reserves should be greater than those currently held, then the locked-in assumptions are revised and a charge for life and annuity benefits is recognized at that time.

Because of the many assumptions and estimates used in establishing reserves and the long-term nature of the contracts, the reserving process, while based on actuarial techniques, is inherently uncertain.

(d) Investments

Short-term investments and fixed maturity investments

Short-term investments comprise investments with a maturity greater than three months but less than one year from the date of purchase. Fixed maturities comprise investments with a maturity of one year and greater from the date of purchase.

Short-term investments and fixed maturities classified as trading are carried at fair value, with realized and unrealized holding gains and losses included in net earnings and reported as net realized and unrealized gains and losses. Investment purchases and sales are recorded on a trade-date basis. Realized gains and losses on the sale of investments are based upon specific identification of the cost of investments.

Short-term investments and fixed maturity investments classified as held-to-maturity securities, which are securities that the Company has the positive intent and ability to hold to maturity, are carried at amortized cost. The cost of short-term investments and fixed maturities are adjusted for amortization of premiums and accretion of discounts.

Fixed maturity investments classified as available-for-sale are carried at fair value, with unrealized gains and losses excluded from net earnings and reported as a separate component of accumulated other comprehensive income. Realized gains and losses on sales of investments classified as available-for-sale are recognized in the consolidated statements of earnings. Amortization of premium or discount is recognized using the effective yield method and included in net investment income. For mortgage-backed and asset-backed investments, and any other holdings for which there is a prepayment risk, prepayment assumptions are evaluated and revised on a regular basis.

Fixed maturity investments classified as available-for-sale and held-to-maturity are reviewed quarterly to determine if they have sustained an impairment of value that is, based on management’s judgment, considered to be other than temporary. The process includes reviewing each fixed maturity investment that is below cost and: (1) determining if the Company has the intent to sell the fixed maturity investment; (2) determining if it is more likely than not that the Company will be required to sell the fixed maturity investment before its anticipated

CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

recovery; and (3) assessing whether a credit loss exists, that is, whether the Company expects that the present value of the cash flows expected to be collected from the fixed maturity investment is less than the amortized cost basis of the investment. In evaluating credit losses, the Company considers a variety of factors in the assessment of a fixed maturity investment including: (1) the time period during which there has been a significant decline below cost; (2) the extent of the decline below cost and par; (3) the potential for the investment to recover in value; (4) an analysis of the financial condition of the issuer; (5) the rating of the issuer; and (6) failure of the issuer of the investment to make scheduled interest or principal payments. If management concludes an investment is other-than-temporarily impaired (“OTTI”), then the difference between the fair value and the amortized cost of the investment is presented as an OTTI charge in the consolidated statements of earnings, with an offset for any noncredit-related loss component of the OTTI charge to be recognized in other comprehensive income. Accordingly, only the credit loss component of the OTTI amount would have an impact on the Company’s earnings.

(e) Redeemable noncontrolling interest

In connection with the acquisition of Arden and with the proposed acquisitions of Torus Insurance Holdings Limited and Atrium Underwriting Group Limited, certain subsidiaries have or will have issued shares to a noncontrolling interest. These shares provide certain redemption rights to the holder which may be settled in the Company’s own shares or cash, at the Company’s option. The Company classifies redeemable noncontrolling interest with redemption features that are not solely within the control of the Company within temporary equity in its consolidated balance sheets and carries them at the redemption value, which is fair value. The Company recognizes changes in the fair value that exceed the carrying value of redeemable noncontrolling interest through retained earnings as if the balance sheet date were also the redemption date. For a description of the redemption rights refer to Note 2—Acquisitions.

New Accounting Standards Adopted in 2013

ASU 2011-11, Disclosures About Offsetting Assets and Liabilities

In December 2011, the FASB issued new disclosure requirements regarding the nature of an entity’s rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under International Financial Reporting Standards. The Company adopted the amended guidance effective January 1, 2013. The adoption of the guidance did not have a material impact on the consolidated financial statements.

ASU 2013-02, Presentation of Items Reclassified from Accumulated Other Comprehensive Income

In February 2013, the FASB issued new disclosure requirements for items reclassified from accumulated other comprehensive income. This guidance requires entities to disclose in a single location (either on the face of the financial statement that reports net earnings or in the notes) the effects of reclassification out of accumulated other comprehensive income. The Company adopted this guidance effective January 1, 2013. The adoption of the guidance did not have a material impact on the consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). The objective of ASU 2013-11 is to improve the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 seeks to reduce the diversity in practice by providing guidance on the presentation of unrecognized tax benefits to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. ASU 2013-11 is effective for annual and interim reporting periods beginning after December 15, 2013, with both early adoption and retrospective application permitted. The Company is currently evaluating the impact of this guidance; however, it is not expected to have a material impact on the Company’s consolidated statements of operations and financial position.

The Company accounts for acquisitions using the purchase method of accounting, which requires that the acquirer record the assets and liabilities acquired at their estimated fair value. The fair values of each of the reinsurance assets and liabilities acquired relating to our acquisitions are derived from estimates of the associated projected cash flows, based on actuarially prepared information and management’s run-off strategy. Refer to Note 2 to the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for more information on the accounting for acquisitions.

Torus Insurance Holdings Limited

(collectively, “First Reserve”) will receive Voting Ordinary Shares, Non-Voting Preferred Shares and cash consideration in the transaction. In the event that the number of Voting Ordinary Shares deliverable to First Reserve at the closing of the Amalgamation would cause First Reserve, as of immediately after such closing, to beneficially own Voting Ordinary Shares that constitute more than 9.5% of the voting power of all shares of the Company, then the Company will issue to First Reserve, at the closing, the total number of shares of Voting Ordinary Shares representing 9.5% of the voting power of all shares of the Company as of immediately after the closing and Non-Voting Preferred Shares representing the remainder of the shares that First Reserve is entitled to under the Amalgamation Agreement. Corsair Specialty Investors, L.P. (“Corsair”) will receive both Voting Ordinary Shares and cash consideration in the transaction. The remaining Torus shareholders will receive all cash. Following the Amalgamation, First Reserve will own approximately 9.5% and 11.5%, respectively, of the Company’s Voting Ordinary Shares and outstanding share capital and Corsair will own approximately 2.5% and 2.1%, respectively, of the Company’s Voting Ordinary Shares and outstanding share capital.

The Company and First Reserve will enter into a Shareholder Rights Agreement at the closing of the Amalgamation, under which the Company has agreed that First Reserve will have the right to designate one representative to the Company’s Board of Directors. This designation right terminates if First Reserve ceases to beneficially own at least 75% of the total number of Voting Ordinary Shares and Non-Voting Preferred Shares acquired by it under the Amalgamation Agreement.

The Company will also enter into a Registration Rights Agreement with First Reserve and Corsair at the closing of the Amalgamation that provides First Reserve and Corsair with certain rights to cause the Company to register under the Securities Act of 1933, as amended (the “Act”), the Voting Ordinary Shares (including the Voting Ordinary Shares into which the Non-Voting Preferred Shares may convert) issued pursuant to the Amalgamation and any securities issued by the Company in connection with the foregoing by way of a share dividend or share split or in connection with any recapitalization, reclassification or similar reorganization (the foregoing, collectively, “Registrable Securities”). Pursuant to the Registration Rights Agreement, the Company must file a resale shelf registration statement for the Registrable Securities within 20 business days after the closing of the Amalgamation.

Trident Co-investment in Torus

In connection with the Amalgamation Agreement, the Company, Kenmare and Trident entered an Investors Agreement on July 8, 2013 governing their investments in Bayshore, and Kenmare and Trident entered into individual equity commitment letters obligating each to fund its respective portion of the purchase price for the Amalgamation described above. Completion of Kenmare’s and Trident’s funding obligations is conditioned on, among other things, the satisfaction of certain conditions tied directly to the satisfaction of the closing conditions under the Amalgamation Agreement.

Upon the funding of the equity commitments at the closing of the Amalgamation, Kenmare and Trident have agreed to enter into a Shareholders’ Agreement (the “Bayshore Shareholders’ Agreement”). Among other things, the Bayshore Shareholders’ Agreement will provide that Kenmare would appoint three members to the Bayshore board of directors and Trident would appoint two members.

The Bayshore Shareholders’ Agreement includes a five-year period during which neither party can transfer its ownership interest in Bayshore to a third party (the “Restricted Period”). Following the Restricted Period: (i) each party must offer the other party the right to buy its shares before the shares are offered to a third party; (ii) Kenmare can require Trident to participate in a sale of Bayshore to a third party as long as Kenmare owns 55% of Bayshore; (iii) each party has the right to be included on a pro rata basis in any sales made by the other party; and (iv) each party has the right to buy its pro rata share of any new securities issued by Bayshore.

During the 90-day period following the fifth anniversary of the closing of the Amalgamation, and at any time following the seventh anniversary of such closing, Kenmare would have the right to redeem Trident’s shares in Bayshore at their then fair market value, which would be payable in cash. Following the seventh anniversary of the closing, Trident would have the right to require Kenmare to purchase Trident’s shares for their then current fair market value, which Kenmare would have the option to pay either in cash or by delivering the Company’s Voting Ordinary Shares.

Trident is a holder of approximately 9.7% of the Company’s Voting Ordinary Shares. Refer to Note 17 for information regarding the Company’s other transactions with affiliates of Trident.

Trident Co-investment in Atrium and Arden

On July 3, 2013, Kenmare entered into an Investors Agreement with Trident with respect to the acquisitions of Atrium and Arden, pursuant to which Trident acquired a 40% interest in Northshore Holdings Ltd., previously a wholly-owned subsidiary of Kenmare (“Northshore”). In connection with the Investors Agreement, Kenmare and Trident provided individual equity commitment letters to Northshore pursuant to which Kenmare and Trident were obligated to provide 60% and 40%, respectively, of the Atrium and Arden purchase prices and related expenses. On September 6, 2013, Kenmare and Trident each funded their individual equity commitments with respect to the Arden acquisition.

Completion of Kenmare’s and Trident’s funding obligations with respect to the Atrium closing is conditioned on, among other things, the satisfaction of certain conditions tied directly to the satisfaction of the closing conditions under the Atrium purchase agreement. In the event that the Atrium acquisition does not close, Trident’s obligations under its commitment letter would terminate as to both Arden and Atrium and Kenmare would be required to purchase at cost Trident’s 40% interest in Northshore.

On September 6, 2013, in connection with the closing of the Arden acquisition, Northshore, Kenmare and Trident entered into the Shareholders’ Agreement (the “Northshore Shareholders’ Agreement”). The Northshore Shareholders’ Agreement, among other things, provides that Kenmare has the right to appoint three members to the Northshore board of directors and Trident has the right to appoint two members. The Northshore Shareholders’ Agreement will also grant Trident the right to designate one member of the Atrium board of directors after the Atrium closing. The Northshore Shareholders’ Agreement includes a five-year period during which neither party can transfer its ownership interest in Northshore to a third party (the “Restricted Period”). Following the Restricted Period: (i) each party must offer the other party the right to buy its shares before the shares are offered to a third party; (ii) Kenmare can require Trident to participate in a sale of Northshore to a third party as long as Kenmare owns 55% of Northshore; (iii) each party has the right to be included on a pro rata basis in any sales made by the other party; and (iv) each party has the right to buy its pro rata share of any new securities issued by Northshore.

The Northshore Shareholders’ Agreement also provides that during the 90-day period following the fifth anniversary of the Arden closing, and at any time following the seventh anniversary of such closing, Kenmare would have the right to redeem Trident’s shares in Northshore at their then fair market value, which would be payable in cash. Following the seventh anniversary of the Arden closing, Trident would have the right to require Kenmare to purchase Trident’s shares in Northshore for their then current fair market value, which Kenmare would have the option to pay either in cash or by delivering the Company’s Voting Ordinary Shares.

Completion of Acquisition of Arden

On September 9, 2013, Kenmare, the Company’s wholly-owned subsidiary, together with Trident, completed the acquisition of Arden. Arden is a Bermuda-based reinsurance company that provides reinsurance to Atrium and is currently in the process of running off certain other discontinued businesses. The purchaser of Arden is 60% owned by Kenmare and 40% owned by Trident. The purchase price for Arden was $79.6 million. Kenmare’s portion of the purchase price was $47.8 million, and was financed by a draw under the Company’s revolving credit facility.

The Company has not completed the determination of fair value of Arden’s reinsurance balances recoverable and losses and loss adjustment expenses primarily because the fair value of these items is impacted

by certain related party transactions between Arden and Atrium that have been provisionally estimated pending the Company’s completion of the acquisition of Atrium. Final fair value determinations are expected to be completed by December 31, 2013 and will be completed within the measurement period, which cannot exceed 12 months from the date of acquisition. As a result, the fair value recorded for these items is a provisional estimate and may be subject to adjustment. Any adjustments may impact the individual and aggregate amounts recorded for assets acquired and liabilities assumed.

The following summarizes the estimated fair values of the assets acquired and the liabilities assumed as of the date of acquisition:

From the date of acquisition to September 30, 2013, the Company recorded revenues and net earnings related to Arden of $0.7 million and $0.1 million, respectively, in its consolidated statement of earnings.

SeaBright

On February 7, 2013, the Company completed its acquisition of SeaBright, through the merger of its indirect, wholly-owned subsidiary, AML Acquisition, Corp. (“AML Acquisition”), with and into SeaBright (the “Merger”), with SeaBright surviving the Merger as the Company’s indirect, wholly-owned subsidiary. SeaBright owns SeaBright Insurance Company, an Illinois-domiciled insurer that is commercially domiciled in California, which wrote direct workers’ compensation business. The aggregate cash purchase price paid by the Company for all equity securities of SeaBright was approximately $252.1 million, which was funded in part with $111.0 million borrowed under a four-year term loan facility provided by National Australia Bank and Barclays Bank PLC.

CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Immediately following the acquisition, SeaBright was placed into run-off, and accordingly is no longer writing new insurance policies. Since its acquisition, SeaBright had renewed expiring insurance policies when it was obligated to do so by regulators, but has received approvals from all states relieving it of this obligation to renew any further policies.

Gross and net premiums written by SeaBright from the date of the acquisition to September 30, 2013 totaled $17.9 million and $10.4 million, respectively. Now that SeaBright’s exit from the mandatory renewal process has been approved, the Company expects that SeaBright will no longer generate premiums written other than for small adjustments related to premium audits and reinstatement premiums on previously written policies.

The purchase price and fair value of the assets acquired in the SeaBright acquisition were as follows:

The following summarizes the estimated fair values of the assets acquired and the liabilities assumed as of the date of acquisition:

From the date of acquisition to September 30, 2013, the Company earned premiums of $100.3 million, recorded losses incurred of $100.3 million on those earned premiums, and recorded $16.1 million in net losses related to SeaBright in its consolidated statement of earnings.

The Pavonia companies wrote various U.S. and Canadian life insurance, including credit life and disability insurance, term life insurance, assumed life reinsurance and annuities.

The purchase price and fair value of the assets acquired in the Pavonia acquisition were as follows:

The following summarizes the estimated fair values of the assets acquired and the liabilities assumed as of the date of acquisition:

As of March 31, 2013, the date of acquisition of the Pavonia companies, all of the companies were either in run-off or, immediately following the acquisition, were placed into run-off, and accordingly are no longer writing any new policies. The Pavonia companies will continue to collect premiums in relation to the unexpired policies assumed on acquisition.

For the period from the date of the acquisition to September 30, 2013, the Company had earned premiums of $63.5 million, recorded life and annuity claim costs of $61.4 million on those earned premiums, and recorded $1.7 million in net losses related to the Pavonia companies in its consolidated statement of earnings.
