HAMILTON, Bermuda, July 30, 2013 /PRNewswire/ -- White Mountains Insurance Group, Ltd. (NYSE: WTM) reported adjusted book value per share of $605 at June 30, 2013, essentially break-even for the second quarter of 2013 and up 3.1% for the first six months of 2013, including dividends.

Ray Barrette, Chairman and CEO, commented, "It was a positive quarter. Good underwriting performance at both Sirius Group and OneBeacon offset losses from investments and a stronger U.S. dollar. Our fixed income portfolio produced an absolute loss as interest rates increased but, thanks to our short duration, performed well on a relative basis. Our value-oriented equity portfolio produced a small gain but underperformed the S&P 500. BAM passed $2 billion of insured par during the quarter, well on its way to becoming the standard in the muni bond insurance market."

Adjusted comprehensive loss was $8 million in the second quarter of 2013, compared to $4 million in the second quarter of last year. Adjusted comprehensive income was $108 million in the first six months of 2013, compared to $114 million in the first six months of last year. Net income attributable to common shareholders was $26 million and $147 million in the second quarter and first six months of 2013, compared to $26 million and $120 million in the second quarter and first six months of last year.

OneBeacon

OneBeacon's book value per share decreased 0.2% for the second quarter and increased 6.7% for the first six months of 2013, including dividends. OneBeacon's GAAP combined ratio was 94% for both the second quarter of 2013 and the second quarter of last year, while the GAAP combined ratio was 91% for the first six months of 2013 compared to 92% for the first six months of last year. The combined ratios for the second quarter and first six months of 2013 reflect slightly higher current accident year loss ratios, offset by lower expense ratios.

Mike Miller, CEO of OneBeacon, said, "We are pleased with our results, reporting a flat book value for the quarter, including dividends, in a rising interest rate environment. Good underwriting offset investment losses, which benefited from our short duration. Year-to-date we grew book value by 6.7%, including dividends. Our continuing specialty businesses grew premiums by 9% in the quarter, helped by positive renewal price increases in all business units. I am pleased to report that we have entered into a long-term partnership with an MGA, The Climate Corporation, a firm that specializes in the crop business. We recently received approval to participate in the federal crop insurance program and will start writing business in the fall. We are very focused on closing the sale of the runoff business soon after the third-party actuarial review is completed later this year. Our balance sheet remains strong, and we continue to see opportunities to grow our specialty businesses."

Net written premiums were $247 million in the second quarter of 2013, a decrease of 16% from the second quarter of last year, while net written premiums were $512 million for the first six months of 2013, a decrease of 14% from the first six months of last year. These decreases were driven by the company's exit from the collector car and boat and energy businesses. Excluding the $67 million and $107 million of net written premiums in the second quarter and first six months of last year related to the exited businesses, net written premiums increased by 9% and 5% in the second quarter and first six months of 2013.

Sirius Group

Sirius Group's GAAP combined ratio was 79% for the second quarter of 2013 compared to 82% for the second quarter of last year, while the GAAP combined ratio was 80% for the first six months of 2013 compared to 83% for the first six months of last year. Higher profit commissions accrued on European property retrocessions, primarily from the 2012 and 2013 underwriting years, improved the combined ratio by 9 points for the quarter and 5 points for the first six months of 2013.

The combined ratio for the second quarter of 2013 included 16 points ($35 million) of catastrophe losses, including $28 million of flood losses in Central Europe and $5 million of tornado losses in the Midwestern United States, compared to 3 points ($7 million) in the second quarter of last year. The combined ratio for the first six months of 2013 included 9 points ($37 million) of catastrophe losses compared to 2 points ($8 million) in the first six months of last year. Favorable loss reserve development was 7 points ($14 million) in the second quarter of 2013 primarily due to reductions in loss reserves for the Japan earthquake and hurricane Sandy compared to no significant loss reserve development in the second quarter of last year. Favorable loss reserve development was 2 points in the first six months of 2013 compared to 1 point in the first six months of last year.

Allan Waters, CEO of Sirius Group, said, "Sirius Group's satisfying combined ratios for the quarter and half year reflect a healthy dose of profit commissions from our property retrocession program. Growth in adjusted book value including dividends for the first six months of 3.5% was muted by the financial impacts of rising interest rates and a strengthening dollar. Our European flood loss was in line with expectations for an event of this magnitude. Property catastrophe excess reinsurance premium rates in the United States are now backtracking a bit but remain adequate. Premium rate trends in other territories and lines of business continue to be mixed. During the quarter we announced our new Capital Markets Initiative and are actively building the infrastructure to meet the ILS needs of our clients and brokers."

In the second quarter of 2013, gross written premiums decreased 6% to $259 million and net written premiums decreased 9% to $205 million, driven by a decrease in the accident and health line, partially offset by increased property business.

HG Global/BAM

For the second quarter and first six months of 2013, HG Global reported pre-tax income of $8 million and $18 million, mostly from interest income on the BAM surplus notes, while BAM reported pre-tax losses of $27 million and $45 million, driven by interest expense on the BAM surplus notes, unrealized investment losses in the second quarter from higher interest rates, and operating expenses. GAAP requires White Mountains to consolidate BAM's results in its financial statements. However, 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.

Sean W. McCarthy, CEO of BAM, said, "We are pleased with the progress we have made in building our business to serve as a utility for the municipal industry. During the first half of this year, we insured over $2 billion of total par in the primary and secondary municipal markets. Importantly, BAM insured more than 50% of all primary issues that were guaranteed, demonstrating our value to the significant number of small and medium sized issuers that benefit from greater access to the market with BAM as their insurer. We believe bond buyers appreciate our focus on insuring essential purpose municipal bonds exclusively and lack of exposure to riskier assets in our insured portfolio."

Other Operations

White Mountains' Other Operations segment reported pre-tax loss of $10 million in the second quarter of 2013 and pre-tax income of $1 million in the first six months of 2013, compared to $22 million and $8 million of pre-tax loss in the second quarter and first six months of last year. The improvement in the results for the second quarter was due primarily to an increase in the value of the Symetra warrants prior to their exercise (see Investment in Symetra Common Shares below) and lower net realized and unrealized investment losses. The improvement for the first six months of 2013 was primarily due to higher net realized and unrealized investment gains, partially offset by lower net investment income and a lower increase in the value of the Symetra warrants than in the first six months of last year.

White Mountains' Other Operations segment reported net realized and unrealized investment losses of $7 million in the second quarter of 2013 and gains of $28 million in the first six months of 2013 compared to net realized and unrealized investment losses of $14 million in the second quarter of last year and gains of $1 million in the first six months of last year. The value of White Mountains' investment in Symetra warrants increased $15 million and $11 million in the second quarter and first six months of 2013 compared to an increase of $6 million and $17 million in the second quarter and first six months of last year. Net investment income decreased to $5 million and $9 million in second quarter and first six months of 2013 from $9 million and $19 million in the second quarter and first six months of last year, primarily due to a lower invested asset base. WM Life Re reported losses of $3 million and $9 million in the second quarter and first six months of 2013 compared to $4 million and $11 million in the second quarter and first six 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.

During the second quarter and first six months of 2013, White Mountains recorded $7 million and $16 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 $17.14 per Symetra common share at June 30, 2013. This compares to Symetra's quoted stock price of $15.99 and Symetra's book value per common share excluding unrealized gains and losses from its fixed maturity investment portfolio of $19.17.

Investment Activities

The GAAP total return on invested assets was -0.8% and 0.6% for the second quarter and first six months of 2013, which included 0.2% and 0.6% of currency losses. This compared to -0.5% and 1.6% for the second quarter and first six months of last year, which included 0.5% and 0.1% of currency losses.

Manning Rountree, President of White Mountains Advisors, said, "The total portfolio was down 0.8% in the quarter. In local currencies, the fixed income portfolio benefited from our short duration and was down 0.7%, a small absolute loss but an excellent relative return, outperforming the Barclay's Intermediate Aggregate Bond Index by 1.1% and trouncing longer-duration indices. The reverse was true of our equity portfolio, which produced a small absolute return of 0.6%, a poor result relative to the S&P 500 return of 2.9%. The U.S. dollar strengthened again in the quarter, reducing total portfolio returns by 0.2%."

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.
