HAMILTON, Bermuda, May 2, 2017 /PRNewswire/ -- White Mountains Insurance Group, Ltd. (NYSE: WTM) reported March 31, 2017 book value per share of $793 and adjusted book value per share of $799. Book value per share and adjusted book value per share were each up 1% for the quarter, including dividends. Including the estimated net gain of $107 per share for the OneBeacon transaction, March 31, 2017 book value per share would be approximately $900 and adjusted book value per share would be approximately $906.

Manning Rountree, CEO, commented, "It was a solid first quarter for White Mountains. We increased adjusted book value per share by 1%, including roughly half a point of one-time compensation and severance expenses. OneBeacon had a nice quarter, producing a 95% combined ratio. BAM posted its best quarter since inception for pricing, total premiums and growth in claims paying resources. The investment portfolio returned 1.5%, a good result."

Rountree continued, "Separately, OneBeacon announced today that it has entered into a definitive agreement to be acquired by Intact Financial in an all-cash transaction for $18.10 per share, or roughly 1.65x tangible book value. Upon closing, this transaction will mark the end of a long and successful chapter in White Mountains's history. We thank Mike Miller and the OneBeacon management team for their many contributions, and we wish them all the best going forward. The transaction will increase our adjusted book value per share by a further 13% and our undeployed capital position by $1.3 billion, from $1.8 billion to $3.1 billion. We are pursuing new opportunities with energy, rigor and discipline."

Comprehensive income attributable to common shareholders was $35 million in the first quarter of 2017, compared to $50 million in the first quarter of 2016. Net income attributable to common shareholders was $34 million in the first quarter of 2017, compared to $13 million in the first quarter of 2016.

OneBeacon

OneBeacon's book value per share increased 3%, including dividends, for the first quarter of 2017. OneBeacon's GAAP combined ratio was 95% for both the first quarter of 2017 and the first quarter of 2016. The loss ratio increased by one point to 58% for the first quarter of 2017 compared to the first quarter of 2016, driven largely by increases in the Program, Healthcare and Government Risks businesses, mostly offset by decreases in several other lines of business. There was no net loss reserve development in either the first quarter of 2017 or the first quarter of 2016. The expense ratio decreased by one point to 37% for the first quarter of 2017 compared to the first quarter of 2016, driven by change in business mix and lower employee costs, which more than offset the negative impact of lower earned premiums.

Mike Miller, CEO of OneBeacon, said, "The year is off to a good start, with 3% growth in book value per share and a 95% combined ratio in the quarter. Most of our businesses delivered strong results, from both a top-line and bottom-line perspective. While overall net written premiums were down 8% compared to last year, that variance was driven by risk-selection refinement in our Program, Entertainment and Healthcare businesses. In the remainder of our businesses, net written premiums were up 3%. While market conditions remain competitive, our positive first-quarter momentum positions us well for the balance of the year."

Net written premiums were $257 million in the in the first quarter of 2017, a decrease of 8% from the first quarter of 2016. During the first quarter of 2017, OneBeacon continued to reduce premiums writings in its Program, Entertainment and Healthcare businesses. Excluding those businesses, net written premiums increased 3% for the first quarter of 2017.

HG Global/BAM

BAM insured municipal bonds with par value of $2.4 billion in the first quarter of 2017, compared to $2.2 billion in the first quarter of 2016. Gross written premiums and member surplus contributions totaled $28 million in the first quarter of 2017, compared to $14 million in the first quarter of 2016. Total pricing (i.e., premiums and member surplus contributions weighted by the par value of bonds insured) was 119 basis points in the first quarter of 2017, up from 62 basis points in the first quarter of 2016. BAM's total claims paying resources increased $19 million to $662 million in the first quarter of 2017, compared to an increase of $6 million to $607 million in the first quarter of 2016.

Bob Cochran, Chairman of BAM, said, "Interest-rate volatility helped drive strong demand for BAM's guaranty during the first quarter, allowing BAM to post a record quarter for gross written premiums and member surplus contributions and growth in claims-paying resources, even as new-issue municipal bond volume declined due to fewer refunding opportunities. Demand was broad-based: BAM's secondary market insurance volume more than quadrupled from the same period in 2016. In the primary market, retail investor demand prompted underwriters to use BAM insurance on portions of larger transactions that would otherwise have sold without a guaranty."

HG Global reported pre-tax income of $7 million in the both the first quarter of 2017 and the first quarter of 2016. In non-controlling interests, White Mountains reported $12 million of GAAP pre-tax loss related to BAM in the first quarter of 2017, compared to $8 million in the first quarter of 2016. The increase in the pre-tax loss was primarily driven by lower realized and unrealized investment gains on BAM's fixed income portfolio in the first quarter of 2017 compared to the first quarter of 2016.

BAM's affairs are managed on a statutory accounting basis, and it does not report stand-alone GAAP financial results. BAM's statutory net loss was $9 million in the first quarter of 2017, compared to an $8 million loss in the first quarter of 2016. As a mutual insurance company that is owned by its members, BAM's results do not affect White Mountains's book value per share or adjusted book value per share. However, White Mountains is required to consolidate BAM's results in its GAAP financial statements, and its results are attributed to non-controlling interests.

Other Operations

White Mountains's Other Operations segment reported pre-tax income of $7 million in the first quarter of 2017, compared to pre-tax loss of $29 million in the first quarter of 2016. The improved results were driven by higher investment returns. The Other Operations segment reported $35 million of net realized and unrealized gains in the first quarter of 2017, compared to $6 million in the first quarter of 2016. The Other Operations segment reported $11 million of net investment income in the first quarter of 2017, compared to $1 million in the first quarter of 2016.

White Mountains's Other Operations segment general and administrative expenses increased $5 million to $76 million in the first quarter of 2017 compared to the first quarter of 2016, driven by $14 million of additional compensation expense recorded in the first quarter of 2017 related to the retirement of the Company's former Chairman and CEO. Incentive compensation costs also reflect increases of 5% and 10% to White Mountains's common share market price during the first quarter of 2017 and the first quarter of 2016.

Investment Activities

The GAAP total return on invested assets was 1.5% for both the first quarter of 2017 and the first quarter of 2016.

Reid Campbell, President of White Mountains Advisors, said, "The total portfolio returned 1.5% for the quarter, a good result driven primarily by the continuing post-election equity market rally. The fixed income portfolio returned 0.9% for the quarter, just ahead of the longer duration Bloomberg Barclays Intermediate Aggregate Index. Fixed income duration edged up slightly during the quarter (from 2.6 years to 2.9 years), while credit quality remained strong. The risk asset portfolio returned 3.7% for the quarter. The principal components of this portfolio-common stocks and high-yield bonds-were in line with their respective indices, while other long-term investments lagged. Risk asset exposure finished the quarter at 23% of the portfolio, up three points from year-end."

Regulation G

This earnings release includes two non-GAAP financial measures that have been reconciled to their most comparable GAAP financial measures.

Adjusted book value per share is a non-GAAP financial measure which is derived by adjusting the GAAP book value per share denominator to exclude unearned restricted common shares, the compensation cost of which, at the date of calculation, has yet to be amortized. In addition, the calculation of adjusted book value per share includes the dilutive effects of outstanding non-qualified options for periods prior to January 20, 2017, the expiration date of the non-qualified options. The reconciliation of GAAP book value per share to adjusted book value per share is included on page 7.

In the third quarter of 2016, White Mountains purchased high-yield fixed maturity investments, which are U.S. dollar denominated publicly traded and 144A debt securities issued by corporations with generally at least one rating between "B-" and "BB+" inclusive by Standard and Poor's or similar ratings from other rating agencies. Given the risk profile of these investments, White Mountains has included returns on high-yield fixed maturity investment returns with returns on common equity securities and other long-term investments. A reconciliation of these returns follows:


                                                                                                      March 31, 2017

    Common equity securities and                                                   GAAP return                Include: Impact of
                                                                                                                      high-                     Reported return
    other long-term investment                                                                               yield fixed maturity
    returns                                                                                                   investments (1)(2)
    -------                                                                                                    -----------------


    Year-to-date                                                                          4.2%                                         (0.5)%                         3.7%
    ------------                                                                           ---                                           -----                           ---



    (1) High-yield fixed maturity investments returned 2.2% for the first quarter of 2017.

    (2) The impact of excluding high-yield fixed maturity investments from the GAAP fixed maturity investment returns was insignificant in the first quarter of 2017.
