HAMILTON, Bermuda, Feb. 5, 2013 /PRNewswire/ -- White Mountains Insurance Group, Ltd. (NYSE: WTM) reported adjusted book value per share of $588 at December 31, 2012, up 2.4% for the quarter and 8.6% for the year, including dividends.

Ray Barrette, Chairman and CEO, commented, "It was a productive year. Investments had a good year with a GAAP total return of 4.9%. OneBeacon finished the year at a 98% GAAP combined ratio, somewhat disappointing even when adjusting for hurricane Sandy claims, though the underlying loss ratio remains solid. Sirius Group reported a full year GAAP combined ratio of 90%, a pleasant result given the magnitude of hurricane Sandy and crop losses. BAM, the new muni bond insurer we funded, is getting traction in the marketplace. The regulatory review of the agreement to sell the OneBeacon runoff is proceeding as expected. We had $76 million in net tax gains in the quarter, mostly from the reduction in the Swedish corporate tax rate, and we successfully protected the value of our foreign tax assets from other changes in Swedish tax laws. We returned $676 million of capital to shareholders, mostly by buying 18% of our beginning shares outstanding at attractive prices. We do not see major business improvements in the near term, as most insurance markets remain quite competitive, new capital is entering the profitable property-cat market, interest rates remain quite low, risk spreads are thin, equities have had a good run and every opportunity continues to be chased by a world full of cash. We remain defensively positioned and in good shape in all areas. We have roughly $1 billion of undeployed capital, and we are actively pursuing potential transactions."

Adjusted comprehensive income was $72 million in the fourth quarter of 2012 and $245 million in the year, compared to $802 million in the fourth quarter of 2011 and $745 million last year. Net income attributable to common shareholders was $68 million in the fourth quarter of 2012 and $207 million in the year, compared to $800 million in the fourth quarter of 2011 and $768 million last year. The 2011 periods include an after-tax gain of $678 million from the sale of Esurance and AFI to Allstate.

OneBeacon

OneBeacon's book value per share decreased 1.4% for the quarter and 0.8% for the year, including dividends. OneBeacon's 2012 results include $101 million of after-tax GAAP losses related to the sale of its runoff business announced in October. OneBeacon's GAAP combined ratio was 112% for the fourth quarter of 2012 compared to 85% for the fourth quarter of 2011, primarily driven by higher catastrophe losses from hurricane Sandy. Higher expenses, lower favorable loss reserve development and higher non-catastrophe current accident year losses also contributed to the increase. The GAAP combined ratio was 98% for 2012 compared to 92% for 2011, primarily driven by higher catastrophe losses, lower favorable loss reserve development and higher expenses.

Mike Miller, CEO of OneBeacon, said, "We had a tough fourth quarter. The combined ratio was high primarily due to losses from hurricane Sandy. Our large marine book accounted for nearly half of our gross losses from Sandy in what is estimated to be the largest marine industry loss in history. The other half came primarily from our collector car and excess property businesses. Underlying loss ratios in our various businesses continue to be good and pricing trends remain encouraging in most of them. Current expense levels are somewhat elevated due to adding two new Specialty segments and staff transfers to Minnesota. We should see a reversing of this trend in 2013. We successfully refinanced our debt for 10 years at good terms in November. We closed the sale of Essentia in early January and will book a nice gain in the first quarter of 2013. The regulatory review of the sale of our runoff business is progressing, and we expect to close in the second half of this year. The closing of that sale will significantly reshape the company, further reducing our risk profile and freeing up capital. With our businesses in good shape and plenty of financial flexibility, we are well positioned to take advantage of opportunities."

The combined ratio for the fourth quarter of 2012 included 15 points of net catastrophe losses ($43 million, including $8 million of ceded reinstatement premiums) compared to 1 point ($3 million) for the fourth quarter of 2011. The combined ratio for 2012 included 5 points of net catastrophe losses ($56 million, including $8 million of ceded reinstatement premiums) compared to 4 points ($37 million) for 2011. There was no prior year loss reserve development in the fourth quarter of 2012 compared to 6 points of favorable loss reserve development in the fourth quarter of 2011. The combined ratio for 2012 included favorable loss reserve development of 1 point compared to 3 points in 2011. The expense ratio was 43% for the fourth quarter of 2012 and 40% for the year, compared to 37% and 38% for the comparable periods of 2011. The increase in both the quarter and full year expense ratio was driven primarily by expenses associated with investments in new businesses and the migration of corporate functions to Minnesota.

Net written premiums were $249 million and $1,179 million in the fourth quarter and year ended December 31, 2012, an increase of 3% and 11% from the comparable periods of last year. Excluding the $8 million of hurricane Sandy-related reinstatement premiums and adjusting for the impact of the change in the method of estimating A.W.G. Dewar written premiums, fourth quarter premiums increased 10% from the fourth quarter of last year. A change in the method of estimating written premiums associated with the A.W.G. Dewar tuition reimbursement insurance product resulted in approximately $9 million in net written premiums being recorded in the third quarter of 2012 that, under the prior method, would have been recorded in the fourth quarter.

In November 2012, OneBeacon completed an offering of $275 million aggregate principal amount of 4.60% Senior Notes due 2022. The proceeds from the issuance were used in December 2012 to redeem all of its 5.875% Senior Notes due 2013. OneBeacon recognized a pre-tax loss of $6 million on the redemption in the fourth quarter of 2012.

In the fourth quarter, OneBeacon recorded a pre-tax gain of $5 million on the sale of a shell company.

Sirius Group

Sirius Group's GAAP combined ratio was 107% for the fourth quarter of 2012 compared to 88% for the fourth quarter of 2011, while the GAAP combined ratio was 90% for 2012 compared to 100% for 2011. The combined ratio for the fourth quarter of 2012 included 42 points ($98 million) of hurricane Sandy losses, net of reinsurance and reinstatement premiums. The combined ratio for 2012 included 13 points ($117 million) of catastrophe losses compared to 24 points ($218 million) for 2011. Catastrophe losses in 2011 were primarily from the Japan earthquake and tsunami and the New Zealand earthquakes. Additionally, the combined ratio for 2012 included 3 points of losses from the agricultural line of business, primarily as a result of the drought in the Midwestern United States. Favorable loss reserve development was 9 points for the fourth quarter of 2012 compared to 6 points for the fourth quarter of 2011. Favorable loss reserve development was 4 points for 2012 compared to 5 points for 2011.

Allan Waters, CEO of Sirius Group, said, "The diversity of our global portfolio benefited us again this year. We reported a solid underwriting profit despite Sandy and the severe U.S. drought. We grew our accident & health and property lines, and pulled back a bit in trade credit due to continuing economic strains in Europe. Overall, gross written premiums increased 6% in local currencies for the year. January 1, 2013 renewals produced modest price improvements and growth. However, industry capacity remains plentiful and the property-cat business is attracting new capital markets entrants. White Mountains Solutions booked $14 million of gains in the fourth quarter, and the deal pipeline looks good. We grew Sirius International regulatory capital by 20% to $2.5 billion."

Gross and net written premiums were flat for the fourth quarter of 2012 from the fourth quarter of 2011, with minimal impacts from foreign exchange. For 2012, gross written premiums increased 4% (6% in local currencies) and net written premiums increased 3% (5% in local currencies) as increases in the accident & health and property lines of business were partially offset by decreases in trade credit.

Financial Guarantee

During the third quarter of 2012, White Mountains capitalized HG Global Ltd. ("HG Global") with approximately $600 million to fund Build America Mutual Assurance Company ("BAM"), a newly formed mutual bond insurer. HG Global provided the initial capitalization of BAM through the purchase of approximately $500 million of BAM surplus notes. HG Global also provides 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. For the fourth quarter and year ended December 31, 2012, HG Global reported pre-tax income of $9 million and $14 million which was driven by interest income on the BAM surplus notes. For the fourth quarter and year ended December 31, 2012, BAM reported pre-tax losses of $18 million and $36 million which was driven by interest expense on the BAM surplus notes and startup and operational costs. 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.

Bob Cochran, Chairman of BAM, said, "We spent the last part of 2012 building our internal capabilities and external understanding of BAM's unique business model and strengths, while making rapid progress on our 50 state licensing process. Beginning in January, BAM has insured a growing number of new issue municipal bonds. Momentum and market recognition are building, and we expect both volume and trading level to improve with increased liquidity, further increasing the value of our guarantee."

Other Operations

White Mountains' Other Operations segment reported pre-tax loss of $5 million and pre-tax income of $8 million in the fourth quarter and year ended December 31, 2012 compared to pre-tax loss of $11 million and $103 million in the comparable periods of last year. The improvement in the fourth quarter was primarily driven by lower losses from WM Life Re and lower incentive compensation expenses, partially offset by lower pre-tax income from investments. The improvement in the year was primarily driven by a mark-to-market gain from the Symetra warrants compared to a loss last year, higher pre-tax income from investments, lower incentive compensation expenses and lower losses from WM Life Re. WM Life Re reported pre-tax loss of $5 million and $19 million in the fourth quarter and year ended December 31, 2012 compared to pre-tax loss of $17 million and $27 million in the comparable periods of last year.

Symetra. The value of White Mountains' investment in Symetra warrants increased $4 million in the fourth quarter of 2012 and $18 million in 2012 compared to an increase of $5 million in the fourth quarter of 2011 and a decrease of $25 million in 2011. During the fourth quarter and year ended December 31, 2012, White Mountains recorded $5 million and $30 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 $16.58 per Symetra common share at December 31, 2012. This compares to Symetra's quoted stock price of $12.98 and Symetra's book value per common share excluding unrealized gains and losses from its fixed maturity investment portfolio of $18.97.

Share Repurchases. White Mountains repurchased and retired 1,329,640 of its common shares for $669 million in 2012 at an average price per share of $503.09. White Mountains repurchased and retired 292,449 shares for $152 million in the fourth quarter of 2012 at an average share price of $518.89, or approximately 88% of White Mountains' December 31, 2012 adjusted book value per share.

Taxes

Effective January 1, 2013, Sweden reduced its corporate tax rate from 26.3% to 22.0%, and Luxembourg increased its corporate tax rate from 28.8% to 29.2%. This resulted in a reduction in Sirius Group's deferred tax liabilities in Sweden and an increase in Sirius Group's net deferred tax assets in Luxembourg at December 31, 2012, for a combined gain of $73 million. In addition, during the quarter Sirius Group had a net release of valuation allowances on deferred tax assets in Luxembourg and White Mountains established a valuation allowance on the deferred tax assets of a group of U.S. companies reported in the Other Operations segment, for a net gain of $3 million. In total, White Mountains recognized $76 million in overall net tax benefits from these changes, which increased White Mountains' adjusted book value per share by $13 in the fourth quarter of 2012.

Investment Activities

The GAAP total return on invested assets for the fourth quarter and year ended December 31, 2012 was 0.7% and 4.9%. Currency translation did not impact the fourth quarter of 2012, while 2012 included 0.5% of currency gains. The GAAP total return for the fourth quarter and year ended December 31, 2011 was 1.2% and 2.9%. Currency translation did not impact the fourth quarter of 2011, while 2011 included 0.2% of currency losses.

Manning Rountree, President of White Mountains Advisors, said, "Investments had a strong finish to the year. The total portfolio was up 0.7% for the quarter and 4.9% for the year. In local currencies, our fixed income portfolio returned 0.4% for the quarter and 3.8% for the year, outperforming the Barclay's Intermediate Aggregate Bond Index over both periods with significantly less duration. Our value-oriented equity portfolio was up 1.4% in the quarter and 7.7% for the year. Equities outperformed the S&P 500 in the second half but underperformed for the full year."

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.
