• Net income attributable to ordinary shareholders, and net income attributable to ordinary shareholders excluding the impact of the GreyCastle Life Retro Arrangements,² of $228.6 million and $173.0 million, respectively, for the quarter and $1.2 billion and $982.1 million, respectively, for the full year

_______________________

¹Defined as net income (loss) attributable to ordinary shareholders excluding: (1) our net investment income - Life Funds Withheld Assets (defined below), net of tax, (2) our net realized (gains) losses on investments sold - excluding Life Funds Withheld Assets, net of tax, (3) our net realized (gains) losses on investments sold (including OTTI) and net unrealized (gains) losses on investments, Trading - Life Funds Withheld Assets, (4) our net realized and unrealized (gains) losses on derivatives, net of tax, (5) our net realized and unrealized (gains) losses on GreyCastle life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets, (6) our share of items (2) and (4) for XL Group plc ("XL")'s insurance company affiliates for the periods presented, (7) our foreign exchange (gains) losses, net of tax, (8) our expenses related to the Catlin acquisition, net of tax, (9) our gain on the sale of our interest in our former operating affiliate, ARX Holding Corp. ("ARX"), (10) our loss on the GreyCastle Life Retro Arrangement, net of tax, (11) our loss on the Other Life Retro Arrangements⁵ and (12) our loss on the early extinguishment of the notes assumed in conjunction with the Catlin acquisition. “Operating net income”, “operating return on average ordinary shareholders' equity" and "operating return on average ordinary shareholders' equity excluding average unrealized gains and losses on investments" are non-GAAP financial measures. See the schedule entitled “Reconciliation” on page 8 of this press release for a reconciliation of “operating net income” to net income (loss) attributable to ordinary shareholders and the calculation of “operating return on average ordinary shareholders' equity" and "operating return on average ordinary shareholders' equity excluding average unrealized gains and losses on investments", both of which are based on operating net income.

²On May 1, 2014, our wholly-owned subsidiary, XL Insurance (Bermuda) Ltd (“XLIB”), entered into a sale and purchase agreement with GreyCastle Holdings Ltd. (“GreyCastle”) providing for the sale of 100% of the common shares of XLIB's wholly-owned subsidiary, XLLR, for $570 million in cash. This transaction was completed on May 30, 2014. As a result of the transaction, we have ceded the majority of our life reinsurance business to XLLR via 100% quota share reinsurance (the "GreyCastle Life Retro Arrangements"). The designated investments that support the GreyCastle Life Retro Arrangements, which are written on a funds withheld basis ("Life Funds Withheld Assets"), are included within "Total investments available for sale" and "Fixed maturities, trading at fair value" on our balance sheet. Investment results for these assets - including interest income, unrealized gains and losses, and gains and losses from sales - are passed directly to the reinsurer pursuant to a contractual arrangement that is accounted for as a derivative. Changes in the fair value of the embedded derivative associated with these GreyCastle Life Retro Arrangements are grouped within "Contribution from GreyCastle Life RetroArrangements" in the schedule entitled "Reconciliation" on page 8 of this press release. Net income attributable to ordinary shareholders excluding the impact of the GreyCastle Life Retro Arrangements is a non-GAAP financial measure.

³Ordinary shareholders' equity is defined as total shareholders' equity less non-controlling interest in equity of consolidated subsidiaries.

⁴Book value per ordinary share, fully diluted book value per ordinary share and fully diluted tangible book value per ordinary share are non-GAAP financial measures. Fully diluted book value per ordinary share represents book value per ordinary share (total shareholders' equity less non-controlling interest in equity of consolidated subsidiaries, divided by the number of outstanding ordinary shares at any period end) combined with the dilutive impact of potential future share issuances at any period end. Fully diluted tangible book value per ordinary share is calculated in the same manner as fully diluted book value per ordinary share except that goodwill and intangible assets are excluded from ordinary shareholders' equity. XL believes that fully diluted tangible book value per ordinary share is a financial measure important to investors and other interested parties who benefit from having a consistent basis for comparison with other companies within the industry. However, this measure may not be comparable to similarly titled measures used by companies either outside or inside of the insurance industry.

⁵During 2015, we entered into a large reinsurance agreement ceding approximately 80% of the remaining life reinsurance premiums that were not included in the GreyCastle Retro Arrangements ("Other Life Retro Arrangements").

Dublin, Ireland – February 3, 2016 – XL Groupplc (“XL” or the “Company”) (NYSE: XL) today reported its fourth quarter and full year 2015 results.

Commenting on the Company’s performance, Chief Executive Officer Mike McGavick said:

“Through 2015 XL produced solid results in a tough (re)insurance market while closing a transformative acquisition and successfully launching XL Catlin. Our colleagues focused on executing a superior integration process that has thus far exceeded our expectations for both business and talent retention as well as synergy savings. Looking to 2016, taking into account the continued pressure from both the (re)insurance and investment markets, we feel we are well positioned to capitalize on our increased market relevance and to find new areas of innovation and opportunity."

Note 1: The Company's results for the twelve months ended December 31, 2015 include those of Catlin Group Limited from May 1, 2015

• Operating net income of $195.0 million for the quarter decreased compared to operating net income of $293.9 million in the prior year quarter. The current quarter includes approximately $73.3 million in integration costs as well as $107.8 million in natural catastrophe losses compared to $31.7 million in natural catastrophe losses in the prior year quarter.

• Operating income excludes the $35.0 million loss associated with the retrocession of the Company's US term life reinsurance business in the fourth quarter.

• Net income (loss) attributable to ordinary shareholders of $228.6 million for the quarter increased compared to $139.5 million in the prior year quarter.

• Net investment income for the quarter was $215.5 million, compared to $226.2 million in the prior year quarter and $225.1 million in the third quarter of 2015. Net investment income excluding the Life Funds Withheld Assets for the quarter was $171.9 million, compared to $172.3 million in the prior year quarter and $178.6 million in the third quarter of 2015.

• Net income from affiliates was $14.7 million for the quarter, compared to net income of $33.5 million in the prior year quarter. This decrease was driven primarily by our hedge fund and investment manager affiliates resulting from the impact of market volatility.

• An income tax benefit of $39.3 million in the quarter and $19.2 million for the full year was driven by the combination of the jurisdictions in which the profits and losses have occurred across the Company's global operations, and the tax benefit recognized as a result of the restructuring of legacy Catlin's U.S. operations.

2

• Fully diluted tangible book value per ordinary share decreased by $0.43 from the prior quarter to $31.52, driven by the decrease in our unrealized gains on investments and our payment of dividends, partially offset by net income.

• Share buybacks totaled 4.7 million shares and $176.7 million during the quarter. At December 31, 2015, $703.3 million of ordinary shares remained available for purchase under our share buyback program.

Note 1: The Company's results for the twelve months ended December 31, 2015 include those of Catlin Group Limited from May 1, 2015

• P&C gross premiums written (“GPW”) in the fourth quarter increased 56.0% compared to the prior year quarter following the combination with Catlin.

• The Insurance segment GPW increased 58.8% from the prior year quarter primarily due to the combination with Catlin.  Excluding the impacts of the additional Catlin business and foreign exchange, the segment experienced an increase of 3.2%. Renewed premium was higher than in prior year quarter driven by our Global Risk Management, Cyber and Marine lines.  In those lines where premium rates did not support our target returns, new and renewal premiums were reduced.  

• The Reinsurance segment GPW also increased 30.3% from the prior year quarter, albeit on a light renewal quarter, primarily due to the combination with Catlin. This was partially offset by the timing of renewals, particularly a large quota share which was extended and renewed at January 1, 2016.

• P&C net premiums earned (“NPE”) in the fourth quarter of $2.4 billion were comprised of $1.64 billion from the Insurance segment and $734.9 million from the Reinsurance segment.

• The P&C loss ratio in the current quarter was 5.8 percentage points higher than in the prior year quarter. Included in the P&C loss ratio was favorable development of $121.2 million compared to $96.7 million in the prior year quarter. The P&C loss ratio variance was impacted by natural catastrophe pre-tax losses net of reinsurance and reinstatement premiums of$107.8 million, compared to $31.7 million in the prior year quarter. Excluding prior year development and natural catastrophe losses the fourth quarter P&C loss ratio was 1.7% higher than the prior year quarter driven in part by several large losses.

• The P&C combined ratio excluding prior year development and the impact of natural catastrophe losses for the quarter was 92.8%, compared to 89.1% for the prior year quarter. The Insurance segment combined ratio on this basis was 95.7% for

3

the quarter compared to 95.4% for the prior year quarter, while the Reinsurance segment combined ratio on this basis was 86.3% for the quarter compared to 73.0% for the prior year quarter, driven by the large losses mentioned above and loss activity in our worldwide agricultural line of business.

• Excluding Catlin related transaction and integration costs, ongoing operating expenses were 37.1% higher than the prior year quarter primarily due to the impact of the combination with Catlin. However, overall run rate expenses for the quarter continue to indicate that synergy savings are being achieved in line or ahead of expectations. The operating expense ratio decreased by 3.3% to 16.9% in the current quarter, compared to 20.2% in the prior year quarter.

Further details of the results for the quarter may be found in the Company’s Financial Supplement,which is dated February 3, 2016 and is available on the Investor Relations section of XL's website.

Note 1: Certain amounts have been reclassified to conform to the current period presentation.

Note 2: The Company's results for the year ended December 31, 2015 include those of Catlin from May 1, 2015.

Note 3: Investment results for the Life Funds Withheld Assets - including interest income, unrealized gains and losses, and gains and losses from sales - are passed directly to the reinsurer pursuant to a contractual arrangement which is accounted for as a derivative. Changes in the fair value of the embedded derivative associated with these GreyCastle Life Retro Arrangements are grouped within "Net realized and unrealized (gains) losses on life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets" in the reconciliation above.

Note 4: Defined as net income (loss) attributable to ordinary shareholders excluding: (1) our net investment income - Life Funds Withheld Assets, net of tax, (2) our net realized (gains) losses on investments sold - excluding Life Funds Withheld Assets, net of tax, (3) our net realized (gains) losses on investments sold (including OTTI) and net unrealized (gains) losses on investments, Trading - Life Funds Withheld Assets, (4) our net realized and unrealized (gains) losses on derivatives, net of tax, (5) our net realized and unrealized (gains) losses on life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets, (6) our share of items (2) and (4) for XL's insurance company affiliates for the periods presented, (7) our foreign exchange (gains) losses, net of tax, (8) our expenses related to the Catlin acquisition, net of tax, (9) our gain on sale of our interest in our operating affiliate, ARX, and (10) our loss on the GreyCastle Life Retro Arrangement, net of tax, (11) our loss on the Other Life Retro Arrangements and (12) our loss on the early extinguishment of the notes assumed in conjunction with the Catlin acquisition. In addition to presenting net income (loss), we believe that showing "operating net income (loss)", "operating return on average ordinary shareholders' equity" and "operating return on average ordinary shareholders' equity excluding average unrealized gains and losses on investments" enables investors and other users of our financial information to analyze our performance in a manner similar to how we analyze our performance. In this regard, we believe that providing only a GAAP presentation of net income (loss) would make it more difficult for users of our financial information to evaluate our underlying business. We also believe that equity analysts and certain rating agencies that follow us (and the insurance industry as a whole) exclude these items from their analyses for the same reasons, and they request that we provide this non-GAAP financial information on a regular basis. A reconciliation of our net income (loss) attributable to ordinary shareholders to operating net income (loss) is provided above.

Note 5: Diluted weighted average number of ordinary shares outstanding is used to calculate per share data except where it is anti-dilutive to earnings per share or where there is a net loss. When it is anti-dilutive or when a net loss occurs, basic weighted average ordinary shares outstanding is utilized in the calculation of net loss per share and net operating loss per share.

Note 6: Ordinary shareholders’ equity is defined as total shareholders’ equity less non-controlling interest in equity of consolidated subsidiaries.

Note 7: Unrealized (gain) loss on investments, net of tax is the cumulative impact of mark to market fluctuations on our investment portfolio that have not been realized through sales.

Comment on Regulation G

XL presents its operations in the way it believes will be most meaningful and useful to investors, analysts, rating agencies and others who use XL’s financial information in evaluating XL’s performance. This press release contains the presentation of (i) operating net income (loss) (“Operating Net Income”), which is defined as net income (loss) attributable to ordinary shareholders excluding: (1) net investment income - Life Funds Withheld Assets, net of tax, (2) net realized (gains) losses on investments sold - excluding Life Funds Withheld Assets, net of tax,(3) net realized (gains) losses on investments sold (including OTTI) and net unrealized (gains) losses on investments, Trading - Life Funds Withheld Assets, (4) net realized and unrealized (gains) losses on derivatives, net of tax, (5) net realized and unrealized (gains) losses on life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets, (6) share of items (2) and (4) for XL's insurance company affiliates for the periods presented, (7) foreign exchange (gains) losses, net of tax, (8) expenses related to the Catlin acquisition, net of tax, (9) gain on the sale of our interest in our operating affiliate, ARX, and (10) the loss on the sale of life reinsurance subsidiary, XLLR, net of tax; (11) our loss on the Other Life Retro Arrangementsand (12) our loss on the early extinguishment of the notes assumed in conjunction with the Catlin acquisition; (ii) return on average ordinary shareholders’ equity (“ROE”) based on operating net income (loss) (“Operating ROE”); (iii) Operating ROE excluding average unrealized gains and losses on investments; (iv) net income (loss) attributable to ordinary shareholders excluding the Contribution from the GreyCastle Life Retro Arrangements and (v) book value per ordinary share (ordinary shareholders’ equity divided by the number of shares outstanding at the period end date), fully diluted book value per ordinary share (book value per share combined with the dilutive impact of potential future share issues at any period end), and fully diluted tangible book value per ordinary share (calculated in the same manner as fully diluted book value per ordinary share except that goodwill and intangible assets are excluded from ordinary shareholders’ equity). These items are "non-GAAP financial measures" as defined in Regulation G. The reconciliation of such measures to the most directly comparable GAAP financial measures in accordance with Regulation G is included in this press release on page 8.

Although the investment of premiums to generate income (or loss) and realize capital gains (or losses) is an integral part of XL’s operations, the determination to realize capital gains (or losses) is independent of the underwriting process. In addition, under applicable GAAP accounting requirements, losses can be created as the result of other than temporary declines in value and from goodwill impairment charges without actual realization. In this regard, certain users of XL’s financial information, including certain rating agencies, evaluate earnings before tax and capital gains to understand the profitability of the operational sources of income without the effects of these two variables. Furthermore, these users believe that, for many companies, the timing of the realization of capital gains and the recognition of goodwill impairment charges are largely a function of economic and interest rate conditions.

Net realized and unrealized (gains) losses on derivatives, net of tax, include all derivatives entered into by XL other than certain credit derivatives and the life retrocession embedded derivative. With respect to credit derivatives, because XL and its insurance company operating affiliates generally hold financial guaranty contracts written in credit default derivative form to maturity, the net effects of the changes in fair value of these credit derivatives are excluded (similar with other companies’ treatment of such contracts) as the changes in fair value each quarter are not indicative of underlying business performance.

Net investment income - Life Funds Withheld Assets, net of tax, and net realized (gains) losses on the life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets, have been excluded because, as a result of

10

the GreyCastle Life Retro Arrangement, XL no longer shares in the risks and rewards of the underlying performance of the Life Funds Withheld Assets that support these retrocession arrangements.  Thereturns on the Life Funds Withheld Assets are passed directly to the reinsurer pursuant to a contractual arrangement that is accounted for as a derivative.  Therefore, net investment income from the Life Funds Withheld Assets and changes in the fair value of the embedded derivative associated with these GreyCastle Life Retro Arrangements are not relevant to XL’s underlying business performance. In addition, the loss on the sale of life reinsurance subsidiary, net of tax, has been excluded due to the one-time, non-operating nature of this loss. 

Foreign exchange (gains) losses in the income statement are only one element of the overall impact of foreign exchange fluctuations on XL’s financial position and are not representative of any economic gain or loss made by XL. Accordingly, it is not a relevant indicator of financial performance and it is excluded.

In summary, XL evaluates the performance of and manages its business to produce an underwriting profit. In addition to presenting net income (loss), XL believes that showing operating net income (loss) enables investors and other users of XL’s financial information to analyze XL’s performance in a manner similar to how management of XL analyzes performance. In this regard, XL believes that providing only a GAAP presentation of net income (loss) would make it much more difficult for users of XL’s financial information to evaluate XL’s underlying business. Also, as stated above, XL believes that the equity analysts and certain rating agencies that follow XL (and the insurance industry as a whole) exclude these items from their analyses for the same reasons and they request that XL provide this non-GAAP financial information on a regular basis.

Operating ROE is a widely used measure of any company’s profitability that is calculated by dividing operating net income for any period other than a fiscal year when actual operating income is used by the average of the opening and closing ordinary shareholders’ equity. XL establishes target Operating ROEs for its total operations, segments and lines of business. If XL’s Operating ROE targets are not met with respect to any line of business over time, XL seeks to re-evaluate these lines. Operating ROE excluding net unrealized gains and losses on investments is an additional measure of a company's profitability that eliminates the impacts of mark to market fluctuations on a company's investment portfolio that have not been realized through sales, which XL believes provides a more consistent measure of company performance.
