1. SIGNIFICANT ACCOUNTING POLICIES

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 preparation of these unaudited condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. While management believes that the amounts included in the unaudited condensed consolidated financial statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company’s principal estimates include, but are not limited to:

The following information should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Certain reclassifications have been made to the prior period reported amounts of net increase (reduction) in ultimate losses and loss adjustment expense liabilities, acquisition costs and life and annuity policy benefits to conform to the current period presentation. These reclassifications had no impact on income or net earnings previously reported.

New Accounting Standards Adopted in 2014

ASU 2013-11 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 adoption of the guidance did not have a material impact on the Company’s consolidated statements of operations and financial position.

2. ACQUISITIONS

Companion Property and Casualty Insurance Company

On August 26, 2014, the Company and Sussex Holdings, Inc. (“Sussex”), an indirect, wholly owned subsidiary of the Company, entered into a definitive agreement for the purchase of all of the shares of Companion Property and Casualty Insurance Company (“Companion”) from Blue Cross and Blue Shield of South Carolina, an independent licensee of the Blue Cross Blue Shield Association.

The total consideration for the transaction will be $218 million in cash. The Company expects to finance the purchase price through a combination of cash on hand and a bank loan facility to be finalized before closing. The Company is a party to the acquisition agreement and has guaranteed the performance by Sussex of its payment and other acquisition-related obligations set forth in the agreement.

Completion of the transaction is conditioned on, among other things, governmental and regulatory approvals and satisfaction of various customary closing conditions. The transaction is expected to close in the fourth quarter of 2014.

(“Kenmare”), a wholly-owned subsidiary of the Company, together with Trident V, L.P., Trident V Parallel Fund, L.P. and Trident V Professionals Fund, L.P., which are managed by Stone Point Capital LLC (collectively, “Trident”), completed the previously announced acquisition of Torus Insurance Holdings Limited (“Torus”).

2. ACQUISITIONS—(Continued)

The purchase price for Torus was established in the amended and restated amalgamation agreement as $646.0 million, to be paid partly in cash and partly in the Company’s stock. The number of Company shares to be issued was fixed at the signing of the amalgamation agreement on July 8, 2013 and was determined by reference to an agreed-upon value per share of $132.448, which was the average closing price of the Company’s voting ordinary shares, par value $1.00 per share (the “Voting Ordinary Shares”), over the 20 trading days prior to such signing date. On the day before closing of the amalgamation, the Voting Ordinary Shares had a closing price of $136.31 per share. At closing, the Company contributed cash of $41.6 million towards the purchase price and $3.6 million towards related transaction expenses, as well as 1,898,326 Voting Ordinary Shares and 714,015 shares of Series B Convertible Participating Non-Voting Perpetual Preferred Stock of the Company (the “Non-Voting Preferred Shares”). Based on a price of $136.31 per share, the Company’s contribution of cash and shares to the purchase price totaled $397.7 million in the aggregate. Trident contributed cash of $258.4 million towards the purchase price and $2.4 million towards related transaction expenses. Based on a price of $136.31 per share, the aggregate purchase price paid by the Company and Trident was $656.1 million.

FR XI Offshore AIV, L.P., First Reserve Fund XII, L.P., FR XII A Parallel Vehicle L.P. and FR Torus Co-Investment, L.P. (collectively, “First Reserve”) received 1,501,211 Voting Ordinary Shares, 714,015 Non-Voting Preferred Shares and cash consideration in the transaction. Following the approval of the Company’s shareholders of an amendment to its bye-laws on June 10, 2014, First Reserve’s Non-Voting Preferred Shares converted on a share-for-share basis into 714,015 shares of newly created Series E Non-Voting Convertible Common Shares (the “Series E Non-Voting Ordinary Shares”). Corsair Specialty Investors, L.P. (“Corsair”) received 397,115 Voting Ordinary Shares and cash consideration in the transaction. The remaining Torus shareholders received all cash. As a result of the amalgamation, First Reserve now owns approximately 9.5% and 11.5%, respectively, of the Company’s Voting Ordinary Shares and outstanding share capital.

Upon the closing of the Torus acquisition, Bayshore, Kenmare and Trident entered into a Shareholders’ Agreement (the “Bayshore Shareholders’ Agreement”), which was subsequently amended, as described in “Dowling Co-investments in Bayshore and Northshore” below.

The purchase price was allocated to the acquired assets and liabilities of Torus based on estimated fair values at the acquisition date. The Company recognized goodwill of $13.0 million, all of which was recorded within the Torus segment and is attributable primarily to Torus’ assembled workforce (refer to note 19 for a description of the Company’s segments). The Company also recognized indefinite lived intangible assets of $23.9 million and other definite lived intangible assets of $20.0 million.

2. ACQUISITIONS—(Continued)

The Company has not completed the process of determining the fair value of its losses and loss adjustment expense reserves, goodwill and intangible assets acquired in the Torus transaction. These valuations will be completed within the measurement period, which cannot exceed 12 months from the acquisition date. As a result, the fair value recorded for these items is a provisional estimate and may be subject to adjustment. Once completed, any adjustments resulting from the valuations may impact the individual amounts recorded for assets acquired and liabilities assumed, as well as the residual goodwill.

Prior to acquisition, Torus ceased underwriting certain lines of business in order to focus on core property, casualty and specialty lines. The results of the discontinued lines of business which were placed into run-off are included within the Company’s non-life run-off segment.

Torus is a global specialty insurer that offers a diverse range of property, casualty and specialty insurance through its operations in the U.K., Continental Europe, the U.S., and Bermuda.

The fair value of the Lloyd’s syndicate capacity was estimated using the multi-period excess-earnings method, a form of the income approach. Lloyd’s syndicate capacity represents Torus’s authorized premium income limit to write insurance business in the Lloyd’s market. The capacity is renewed annually at no cost to the Company but may be freely purchased or sold, subject to Lloyd’s

approval. The ability to write insurance business within the syndicate capacity is indefinite, with the premium income limit being set annually by the Company, subject to Lloyd’s approval.

U.S. insurance licenses represent the intangible asset related to Torus’ licenses and have been valued based on recent market transactions.

Technology represents the intangible asset related to Torus’ capitalized software and has been valued on a replacement cost basis.

Brand represents the intangible asset related to the Torus name and was valued using the income approach.

From April 1, 2014, the date of acquisition, to September 30, 2014, the Company earned premiums of $258.5 million, recorded net increase in ultimate losses and loss adjustment expense liabilities of $159.6 million on those earned premiums, and recorded $18.7 million in net loss in its consolidated statement of earnings related to the active underwriting portion of the Torus segment.

From the date of acquisition to September 30, 2014, the Company earned premiums of $29.1 million, recorded net increase in ultimate losses and loss adjustment expense liabilities of $17.6 million on those earned premiums, and recorded $7.4 million in net earnings in its consolidated statement of earnings related to Torus’ non-life run-off business.

Supplemental Pro Forma Financial Information (Unaudited)

The operating results for Torus have been included in the unaudited condensed consolidated financial statements from the date of acquisition. The following pro forma condensed combined statement of earnings for the three months ended September 30, 2013 and the nine months ended September 30, 2014 and 2013 combines the historical consolidated statements of earnings of the Company with those historical consolidated statements of earnings of Torus, giving effect to the business combinations and related transactions as if they had occurred on January 1, 2013 and 2014, as applicable.

long-term incentive plans that awarded time-based restricted shares of Northshore to certain Atrium employees. These equity awards will have the effect of modestly reducing Kenmare’s equity interest in Northshore (as well as Trident’s equity interest) over the course of the vesting periods as Atrium employees acquire shares. Shares generally vest over two to three years, although certain awards began vesting in 2014.

Dowling Co-investments in Bayshore and Northshore

On May 8, 2014, Dowling Capital Partners I, L.P. (“Dowling”) purchased common shares of both Bayshore and Northshore from Kenmare and Trident (on a pro rata basis in accordance with their respective interests) for an aggregate amount of $15.4 million.

Prior to the sale of shares to Dowling, Kenmare and Trident owned 60% and 40% of Bayshore, respectively, and 57.1% and 38.1% of Northshore on a fully diluted basis, respectively (assuming full vesting of Atrium employees’ restricted shares totaling 4.8%). Following the sale of Bayshore shares to Dowling, Kenmare, Trident and Dowling own 59.0%, 39.3% and 1.7% of Bayshore, respectively. Following the sale of Northshore shares to Dowling, Kenmare, Trident, certain Atrium employees and Dowling own 56.1%, 37.4%, 4.8% and 1.7% of Northshore, respectively, on a fully diluted basis. ¹

In connection with the sale of Bayshore shares, the Bayshore Shareholders’ Agreement was amended and restated. The Amended and Restated Bayshore Shareholders’ Agreement, among other things, provides that Kenmare has the right to appoint three members to the Bayshore board of directors and Trident has the right to appoint two members. The Amended and Restated Bayshore Shareholders’ Agreement includes a five-year period (the “Restricted Period”) during which no shareholder can transfer its ownership interest in Bayshore to a third party unless approved by a super-majority of the shareholders. Following the Restricted Period: (i) each shareholder must offer Kenmare and Trident the right to buy its shares before the shares are offered to a third party; (ii) Kenmare can require each other shareholder to participate in a sale of Bayshore to a third party as long as Kenmare owns 55% of the aggregate number of outstanding shares of Bayshore held by Kenmare and Trident; (iii) each shareholder has the right to be included on a pro rata basis in any sales made by another shareholder; and (iv) each of Kenmare, Trident and Dowling has the right to buy its pro rata share of any new securities issued by Bayshore.

The Amended and Restated Bayshore Shareholders’ Agreement also provides that during the 90-day period following the fifth anniversary of the Torus closing, and at any time following the seventh anniversary of such closing, Kenmare would have the right to purchase the Bayshore shares owned by all other shareholders of Bayshore at their then fair market value, which would be payable in cash. Following the seventh anniversary of the Torus closing, Trident would have the right to require Kenmare to purchase all of Trident’s shares in Bayshore for their then current fair market value and Dowling would have the right to participate in such transaction by requiring Kenmare to purchase all of its shares in Bayshore on the same terms. Kenmare would have the option to pay for such shares either in cash or by delivering the Company’s Voting Ordinary Shares.

In connection with the sale of Northshore shares, the Northshore Shareholders’ Agreement was amended and restated. The Amended and Restated Northshore Shareholders’ Agreement provides for

substantially the same rights and obligations as the Amended and Restated Bayshore Shareholders’ Agreement, except that the fifth and seventh anniversaries refer to the Arden closing (which occurred on September 9, 2013).

4. INVESTMENTS

The Company holds: (i) trading portfolios of fixed maturity investments, short-term investments and equities; (ii) a held-to-maturity portfolio of fixed maturity investments; and (iii) available-for-sale portfolios of fixed maturity and short-term investments. The Company’s trading and available-for-sale portfolios are recorded at fair value. The Company’s held-to-maturity portfolio is recorded at amortized cost.

In the normal course of the Company’s investing activities, it actively manages allocations to non-controlling tranches of structured securities issued by variable interest entities (“VIEs”). These structured securities include residential mortgage-backed, commercial mortgage-backed and asset-backed securities and are included in the tables below.

In addition to these securities, the Company also invests in private equity funds, fixed income funds, fixed income hedge funds, equity and real estate debt funds and collateralized loan obligation (“CLO”) equity-tranched securities, which are all variable interests issued by VIEs. For these variable

interests, the Company does not have the power to direct the activities that are most significant to the economic performance of the VIEs and, accordingly, it is not the primary beneficiary for any of these VIEs. The Company’s maximum exposure to loss on these interests is limited to the amount of its investment. The Company has not provided financial or other support with respect to these structured securities other than its original investment.

Included within residential and commercial mortgage-backed securities as at September 30, 2014 were securities issued by U.S. governmental agencies with a fair value of $283.8 million (as at December 31, 2013: $177.9 million).

The increase in the Company’s investments classified as trading securities of $448.9 million was due primarily to additional fixed maturity investments acquired in the Torus acquisition.

The following tables set forth certain information regarding the credit ratings (provided by major rating agencies) of the Company’s fixed maturity and short-term investments classified as trading:
