HAMILTON, Bermuda, Oct. 28, 2013 /PRNewswire/ -- White Mountains Insurance Group, Ltd. (NYSE: WTM) reported adjusted book value per share of $622 at September 30, 2013, up 2.8% for the quarter and 5.9% for the first nine months of 2013, including dividends.

Ray Barrette, Chairman and CEO, commented, "It was a nice quarter. Investment returns were good, helped by a rising stock market and weakening dollar. OneBeacon reported 3.8% growth in book value, with investments and transaction gains helping a 96% combined ratio. Sirius reported an 89% combined ratio, another good quarter with low catastrophe losses. BAM continues to make good progress despite a slow municipal issuance market, passing the $3 billion mark for gross par insured. We remain active but patient in looking for opportunities to deploy our capital."

Adjusted comprehensive income was $104 million and $212 million in the third quarter and first nine months of 2013, compared to $59 million and $173 million in the third quarter and first nine months of last year. Net income attributable to common shareholders was $57 million and $204 million in the third quarter and first nine months of 2013, compared to $19 million and $139 million in the third quarter and first nine months of last year.

OneBeacon

OneBeacon's book value per share increased 3.8% for the third quarter and 10.8% for the first nine months of 2013, including dividends. OneBeacon's GAAP combined ratio was 96% and 93% for the third quarter and first nine months of 2013, compared to 95% and 93% for the third quarter and first nine months of last year. The combined ratios for the third quarter and first nine months of 2013 reflect higher loss ratios and lower expense ratios when compared to the 2012 periods. Comprehensive income in the third quarter of 2013 includes a $7 million benefit from the release of a tax valuation allowance and $4 million of pre-tax other revenues from the extension of a transition service agreement with Tower, the buyer of OneBeacon's personal lines business.

Mike Miller, CEO of OneBeacon, said, "We are pleased with our 11% growth in book value and 93% combined ratio reported through the first nine months of this year. For the third quarter, strong book value growth was primarily driven by good investment results and acceptable underwriting results that were somewhat impacted by a few large property losses in the Specialty Property business. We expect to receive regulatory approval of the runoff sale in the second quarter of 2014."

Net written premiums were $314 million in the third quarter of 2013, a decrease of 6% from the third quarter of last year, while net written premiums were $826 million in the first nine months of 2013, a decrease of 11% from the first nine months of last year. Excluding the $60 million and $167 million of net written premiums related to exited businesses, net written premiums increased by 14% and 8% in third quarter and first nine months of 2013.

Sirius Group

Sirius Group's GAAP combined ratio was 89% for the third quarter of 2013 compared to 88% for the third quarter of last year, while the GAAP combined ratio was 83% for the first nine months of 2013 compared to 85% for the first nine months of last year. The combined ratio for the third quarter of 2013 includes 14 points ($31 million) of catastrophe losses, including $18 million from hail storm losses in Germany and $6 million of flood losses in India, compared to 3 points ($6 million) of catastrophe losses in the third quarter of last year. The combined ratio for the first nine months of 2013 includes 11 points ($68 million) of catastrophe losses compared to 2 points ($14 million) in the first nine months of last year. Favorable loss reserve development was 7 points ($15 million) in the third quarter of 2013, primarily due to reductions in property loss reserves from recent underwriting years, compared to 3 points in the third quarter of last year. Favorable loss reserve development was 4 points ($26 million) in the first nine months of 2013 compared to 2 points in the first nine months of last year. The combined ratio for the third quarter and first nine months of 2012 also includes 19 points and 7 points, respectively, from $45 million of agricultural losses incurred in the third quarter of 2012, primarily as a result of the drought in the Midwestern United States.

Allan Waters, CEO of Sirius Group, said, "Our 83% combined ratio for the first nine months reflects good underwriting combined with low catastrophe losses. Sirius Group's adjusted book value per share grew 7% over the first nine months, including dividends. We expect continued pressure on rates in most lines of business through the January 1, 2014 renewals, particularly U.S. property catastrophe excess business. Sirius Capital Markets should begin raising third party capital this quarter."

Gross written premiums decreased 7% to $236 million and net written premiums decreased 12% to $196 million in the third quarter of 2013, while gross written premiums decreased 5% to $947 million and net written premiums decreased 8% to $736 million in the first nine months of 2013, mainly due to a decline in the accident and health line, partially offset by increases in property lines.

HG Global/BAM

For the third quarter and first nine months of 2013, HG Global reported pre-tax income of $11 million and $28 million, mostly from interest income on the BAM surplus notes, while BAM contributed GAAP pre-tax losses of $15 million and $60 million, driven by interest expense on its surplus notes, unrealized investment losses in the second quarter from higher interest rates, and operating expenses. BAM does not report stand alone GAAP financial results but White Mountains is required to consolidate BAM's results in its GAAP financial statements. Since BAM is a mutual insurance company that is owned by its members, BAM's results do not affect White Mountains' adjusted book value per share and are attributed to non-controlling interests. BAM manages its affairs on a statutory accounting basis. BAM's statutory surplus includes surplus notes and is not reduced by accruals of interest expense on the surplus notes. BAM's statutory surplus is reduced only after a payment of principal or interest has been approved by the New York Department of Financial Services.

Robert P. Cochran, Chairman of BAM, said, "We continue to make good progress in building BAM's franchise. During the third quarter, we grew our market penetration to over 42%, bringing the aggregate par insured for the first three quarters to approximately $3.4 billion. Most important, despite lower overall market volume, we continued to increase the number of small and medium-sized issuers that benefit from becoming mutual members of BAM. In another significant development, BAM was licensed to operate in the state of Florida, leaving only one more state to complete our nationwide licensing. Lastly, in an August credit rating report, Standard & Poor's Ratings Services reaffirmed our AA/Stable rating, which is the highest S&P rating in our industry."

Other Operations

White Mountains' Other Operations segment reported pre-tax income of $8 million and $9 million in the third quarter and first nine months of 2013, compared to $21 million and $13 million in the third quarter and first nine months of last year. The results for White Mountains' Other Operations for all periods were driven by the results of investment assets contained within the segment.

White Mountains' Other Operations segment reported net realized and unrealized investment gains of $33 million and $61 million in the third quarter and first nine months of 2013 compared to $40 million and $41 million in the third quarter and first nine months of last year. Net investment income decreased to $2 million and $12 million in third quarter and first nine months of 2013 from $7 million and $27 million in the third quarter and first nine months of last year, primarily due to a lower invested asset base and lower investment yields. WM Life Re reported losses of $7 million and $16 million in the third quarter and first nine months of 2013 compared to $3 million and $14 million in the third quarter and first nine months of last year.

Investment in Symetra Common Shares

During the second quarter of 2013, White Mountains executed a cashless exercise of its Symetra warrants. The cashless exercise resulted in the issuance of 2,648,879 additional common shares of Symetra in exchange for the warrants to purchase 9,487,872 Symetra common shares. The value of White Mountains' investment in Symetra warrants increased $11 million in the first six months of 2013 prior to the exercise. The value of the Symetra warrants decreased $4 million in the third quarter of last year and increased $14 million in the first nine months of last year.

During the third quarter and first nine months of 2013, White Mountains recorded $8 million and $24 million in equity in earnings from its investment in Symetra's common shares, which increased the value of the investment in Symetra's common shares used in the calculation of White Mountains' adjusted book value per share to $17.49 per Symetra common share at September 30, 2013. This compares to Symetra's quoted stock price of $17.82 and Symetra's book value per common share excluding unrealized gains and losses from its fixed maturity investment portfolio of $19.47.

Investment Activities

The GAAP total return on invested assets was 1.9% and 2.5% for the third quarter and first nine months of 2013, which included 0.6% and 0.0% of currency gains. This compared to a GAAP total return of 2.7% and 4.3% for the third quarter and first nine months of last year, which included 0.6% and 0.4% of currency gains.

Manning Rountree, President of White Mountains Advisors, said, "The total portfolio was up 1.9% in the quarter, a strong result. In local currencies, the fixed income portfolio was up 0.4%, lagging the Barclay's Intermediate Aggregate Bond Index as rates fell in the quarter. The total equity portfolio was up 4.8%, and our two largest separate accounts, Prospector and Lateef, both outperformed the S&P 500 return in the quarter. The U.S. dollar weakened, increasing total portfolio returns by 0.6% for the quarter, essentially reversing the currency-related losses in the first half of 2013."

Regulation G

This earnings release includes two non-GAAP financial measures that have been reconciled to their most comparable GAAP financial measures. White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains' financial performance.

Adjusted book value per share is a non-GAAP financial measure which is derived by expanding the calculation of GAAP book value per share to exclude equity in net unrealized gains (losses) from Symetra's fixed maturity portfolio, net of applicable taxes, from book value. In addition, the number of common shares outstanding used in the calculation of adjusted book value per share are adjusted to exclude unearned restricted common shares, the compensation cost of which, at the date of calculation, has yet to be amortized. The reconciliation of adjusted book value per share to GAAP book value per share is included on page 7.

Adjusted comprehensive income (loss) is a non-GAAP financial measure that excludes the change in equity in net unrealized gains (losses) from Symetra's fixed maturity portfolio, net of applicable taxes, from comprehensive income (loss) attributable to White Mountains' common shareholders. The reconciliation of adjusted comprehensive income (loss) to GAAP comprehensive income (loss) attributable to White Mountains' common shareholders is included on page 8.

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances.

    --  the risks associated with Item 1A of White Mountains' 2012 Annual Report
        on Form 10-K;
    --  claims arising from catastrophic events, such as hurricanes,
        earthquakes, floods, fires, terrorist attacks or severe winter weather;

        insurers and reinsurers;
    --  changes in domestic or foreign laws or regulations, or their
        interpretation, applicable to White Mountains, its competitors or its
        customers;
    --  an economic downturn or other economic conditions adversely affecting
        its financial position;
    --  recorded loss reserves subsequently proving to have been inadequate;
    --  actions taken by ratings agencies from time to time, such as financial
        strength or credit ratings downgrades or placing ratings on negative
        watch;
    --  other factors, most of which are beyond White Mountains' control.

Consequently, all of the forward-looking statements made in this earnings release are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations.
