In December 2014, OneBeacon completed the sale of its runoff business (the “Runoff Transaction”). Accordingly, OneBeacon’s runoff business is presented as discontinued operations. (See Note 17 - “Discontinued Operations”). for discontinued operations.)In the second quarter of 2015, OneBeacon currently owns propertycompleted the sale of its building in Canton, MA for which it has entered into an agreement to sell and which is$58.0 million. The building was presented as held for sale. As of March 31, 2015 andsale at December 31, 2014, the carrying value of the property was $58.0 million and $58.1 million.2014.
The Sirius Group segment consists of Sirius International Insurance Group, Ltd., an exempted Bermuda limited liability company, and its subsidiaries (collectively, “Sirius Group”). Sirius Group provides insurance and reinsurance products for property, accident and health, aviation and space, trade credit, marine, agriculture and certain other exposures on a worldwide basis through its primary subsidiaries, Sirius International Insurance Corporation (“Sirius International”), Sirius America Insurance Company (“Sirius America”) and Lloyds Syndicate 1945 (“Syndicate 1945”). Sirius Group also specializes in the acquisition and management of runoff insurance and reinsurance companies both in the United States and internationally through its White Mountains Solutions division (“WM Solutions”). On July 27, 2015, White Mountains announced it signed a definitive agreement to sell Sirius Group to CM International Holding PTE Ltd., the Singapore-based investment arm of China Minsheng Investment Corp., Ltd. (“CMI”). The purchase price will be paid in cash in an amount equal to 127.3% of Sirius’s closing date tangible common shareholder’s equity plus $10.0 million. Based on Sirius's tangible common shareholder's equity at December 31, 2014, the purchase price would be $2.2 billion. (See Note 19 - “Subsequent Events”).
The HG Global/BAM segment consists of HG Global Ltd. (“HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”). BAM is a municipal bond insurer domiciled in New York that was established in 2012 to provide insurance on bonds issued to support essential U.S. public purposes such as schools, utilities, core governmental functions and existing transportation facilities. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503.0 million of surplus notes issued by BAM (the “BAM Surplus Notes”). HG Global, through its wholly-owned subsidiary, HG Re Ltd. (“HG Re”), also provides 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. As of both March 31,June 30, 2015 and December 31, 2014, White Mountains owned 96.9% of HG Global's preferred equity and 88.4% of its common equity.

White Mountains’s Other Operations segment consists of the Company and its intermediate holding companies, its wholly-owned investment management subsidiary, White Mountains Advisors LLC (“WM Advisors”), White Mountains’s variable annuity reinsurance business, White Mountains Life Reinsurance (Bermuda) Ltd. (“Life Re Bermuda”), which is in runoff with all of its contracts maturing by June 30, 2016, and its U.S.-based service provider, White Mountains Financial Services LLC (collectively, “WM Life Re”), and White Mountains’s ownership positions in Tranzact Holdings, LLC, Wobi Insurance Agency Ltd.

However, as a result of SSRM’s role as the attorney-in-fact to SSIE and the investment in SSIE’s surplus notes, White Mountains is required to consolidate SSIE in its GAAP financial statements. SSIE’s results do not affect White Mountains’s common shareholders’ equity as they are attributable to non-controlling interests.

All significant intercompany transactions have been eliminated in consolidation. Certain amounts in the prior period financial statements have been reclassified to conform to the current presentation. These interim financial statements include all adjustments considered necessary by management to fairly present the financial position, results of operations and cash flows of White Mountains. These interim financial statements may not be indicative of financial results for the full year and should be read in conjunction with the Company’s 2014 Annual Report on Form 10-K.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  Refer to the Company’s 2014 Annual Report on Form 10-K for a complete discussion regarding White Mountains’s significant accounting policies.
 
Recently Adopted Changes in Accounting Principles
 
Qualified Affordable Housing Projects
Effective January 1, 2015, White Mountains adopted ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects (“QAHP”) (ASC 323). ASU 2014-01 allows investors in QAHP to make a policy election to use the proportional amortization method. Under the proportional amortization method, the investor amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the investment results, net of the related tax benefits, as a component of income tax expense. Prior to adoption, White Mountains accounted for its QAHP investment under the equity method and recognized its share of its QAHP investment's losses in investment income. White Mountains made the policy election to account for its investment in its QAHP investment using the proportional amortization method, applied retrospectively. Under the proportional amortization method, the cumulative loss recognized through MarchDecember 31, 2015 increased by $1.22014 and December 31, 2013 was $0.9 million and $0.5 million. As a result of the retrospective adoption, White Mountains's common shareholders equity has been reduced by $0.5 million as of January 1, 2014. In addition, theThe retrospective adoption resulted in an increase of $0.4$0.5 million and $0.9 million to net investment income and a net increase of $0.6 million and $1.2 million to income tax expense for the three and six months ended March 31,June 30, 2014. Footnote disclosures for prior year amounts have been amended to be consistent with the restated amounts described above.

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity
On April 10, 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (ASC 205 and ASC 360) to reduce diversity in practice for reporting discontinued operations. ASU 2014-08 limits discontinued operations treatment to disposals that represent a strategic shift and that have a major effect on a reporting entity’s operations and financial results to be reported as discontinued operations. The revised guidance also requires expanded disclosure in the financial statements for discontinued operations as well as for disposals of significant components of an entity that do not qualify for discontinued operations presentation. White Mountains has not had any transactions that occurred since ASU 2014-08 became effective on December 15, 2014.


6

Pushdown Accounting
ASU 2014-17, Pushdown Accounting, a consensus of the FASB Emerging Issues Task Force (ASC 805) became effective upon its issuance on November 18, 2014. The new guidance, which is applicable prospectively, gives an acquired non-public company the option to apply pushdown accounting in its separate company financial statements in the period in which it is acquired in a change of control transaction. Once pushdown accounting has been applied, the election is irreversible. Acquired entities that chose not to apply pushdown accounting at the time of acquisition, may apply pushdown accounting in a subsequent period as a change in accounting principle under ASC 250, Accounting Changes and Error Corrections. White Mountains has not had any acquisitions since AUS 2014-17 became effective.


6

Unrecognized Tax Benefits
Effective January 1, 2014, White Mountains adopted ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASC 740). The new ASU requires balance sheet presentation of an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (“NOL”) carryforward or tax credit carryforward rather than as a liability. The exception is in circumstances where a carryforward is not available to settle the additional taxes that might arise upon disallowance of the tax position under the tax law of the applicable jurisdiction. Prior to the issuance of ASU 2013-11, the guidance for unrecognized tax benefits under ASC 740 did not provide explicit guidance on whether an entity should present an unrecognized tax benefit as a liability or as a reduction of NOL carryforwards or other tax credits. In circumstances where an NOL carryforward is not available to offset settlement of any additional taxes arising from a disallowed tax position, the unrecognized tax benefit should be presented as a liability. The new guidance became effective for White Mountains on January 1, 2014. Adoption did not have any impact on White Mountains's financial condition, results of operations or cash flows or financial statement presentation.
 
Recently Issued Accounting Pronouncements

Short-Duration Contracts
On May 21, 2015, the FASB issued ASU 2015-09, Disclosures about Short Duration Contracts (ASC 944) which requires expanded footnote disclosures about loss and loss adjustment expense (“LAE”) reserves. Under the new guidance, some disclosures currently presented outside of White Mountains’s financial statements, such as loss development tables and a reconciliation of loss development data to the loss and LAE reserves reflected on the balance sheet, will become part of the financial statement footnotes. In addition, the loss development tables required to be presented under the new ASU must be presented on a disaggregated basis by accident year rather than by reporting year as currently presented. Some of the expanded disclosures are new requirements, such as the disclosure of reserves for losses incurred but not reported (“IBNR”) plus expected development on reported claims, which must be presented by accident year on a disaggregated basis. The new guidance also requires new disclosures about claim frequency data together with descriptions of the approach used to measure that data. Qualitative descriptions of methodologies and assumptions used to develop IBNR estimates must be presented together with the disaggregated amounts of IBNR to which they relate, along with a discussion of any significant changes in methodology and assumptions and the related effect upon the loss reserves. The new guidance will be effective for annual periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2016 with retrospective restatement of prior periods required. White Mountains will modify its financial statement footnote disclosures to conform to the requirements of ASU 2015-09 upon adoption, including revisions to prior year’s disclosures.

Fair Value Measurements
On May 1, 2015, the FASB issued ASU 2015-07, Fair Value Measurement - Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent) (ASC 820) which eliminates the requirement to disclose the fair value hierarchy level for investments for which fair value is measured at net asset value using the practical expedient in ASC 820. White Mountains measures the fair value of its investments in hedge funds and private equity funds using this practical expedient and has classified those measurements within Level 3 of the fair value hierarchy. The new guidance is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years.


7

Debt Issuance Costs
On April 7, 2015, the FASB issued ASU 2015-03, Imputation of Interest (ASC 835) which requires debt issuance costs related to a recognized debt liability to be presented as a deduction from the carrying amount of the related debt, consistent with the treatment required for debt discounts. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. White Mountains does not expect ASU 2015-03 to impact its financial position, results of operations, cash flows, presentation and disclosures.

Amendments to Consolidation Analysis
On February 18, 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (ASC 810) which amends the guidance for determining whether an entity is a variable interest entity (“VIE”). ASU 2015-02 eliminates the separate consolidation guidance for limited partnerships and with it, the presumption that a general partner should consolidate a limited partnership. In addition, ASU 2015-02 changes the guidance for determining if fee arrangements qualify as variable interests and the effect fee arrangements have on the determination of the primary beneficiary. ASU 2015-02 is effective for annual and interim reporting periods beginning after December 15, 2015 and must be applied retrospectively. White Mountains does not expect ASU 2015-02 to affect the consolidation analysis for any of its existing investments.

Share-Based Compensation Awards
On June 19, 2014, the FASB issued ASU 2014-12, Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASC 718). The new guidance is intended to eliminate diversity in practice for employee share-based awards containing performance targets that could be achieved after the requisite service period. Some reporting entities account for performance targets that can be achieved after the requisite service period as performance conditions that affect the vesting of the award while other reporting entities treat those performance targets as non-vesting conditions that affect the grant-date fair value of the award. The updated guidance requires that a performance target that affects vesting and that can be achieved after the requisite service period be treated as a performance condition. Compensation cost should be recognized in the period it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which service has been rendered. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2015. White Mountains does not expect adoption to have a significant effect on its financial position, results of operations, cash flows, presentation or disclosures.

Revenue Recognition
On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), which modifies the guidance for revenue recognition. The scope of the new ASU excludes insurance contracts but is applicable to certain fee arrangements, such as third-party investment management fees charged by White Mountains Advisors, which were $2.0 million and $4.4$4.0 million for the three and six months ended March 31,June 30, 2015 and 2014, respectively.$3.0 million and $6.0 million for the three and six months ended June 30, 2014. White Mountains is in the process of evaluating the new guidance and has not yet determined the potential effect of adoption on its financial position, results of operations, or cash flows. ASU 2014-09 is effective for annual and interim reporting periods beginning after December 15, 2016.

Note 4. Third Party Reinsurance
 
In the normal course of business, White Mountains’s insurance and reinsurance subsidiaries may seek to limit losses that may arise from catastrophes or other events by reinsuring with third party reinsurers. White Mountains remains liable for risks reinsured in the event that the reinsurer does not honor its obligations under reinsurance contracts.
 
OneBeacon
At March 31,June 30, 2015, OneBeacon had $18.220.9 million and $141.6147.1 million of reinsurance recoverables on paid and unpaid losses. At December 31, 2014, OneBeacon had $12.2 million and $161.6 million of reinsurance recoverables on paid and unpaid losses. The reinsurance balances associated with the Runoff Business are included in discontinued operations (seeoperations. (See Note 17 - “Discontinued Operations”). Reinsurance contracts do not relieve OneBeacon of its obligation to its policyholders. OneBeacon is selective with its reinsurers, placing reinsurance with only those reinsurers having a strong financial condition. OneBeacon monitors the financial strength and ratings of its reinsurers on an ongoing basis. Uncollectible amounts related to the ongoing specialty business historically have not been significant.
Except as discussed below, there have been no material changes to OneBeacon's reinsurance coverage as discussed in Note 4 —“Reinsurance” in White Mountains’s 2014 Annual Report on Form 10-K.
Effective January 1, 2015, OneBeacon purchased an aggregate stop loss on its multiple periodperil crop insurance ("MPCI"(“MPCI”) portfolio, providing 52.0% of coverage in excess of a 98.0% loss ratio on premiums covered by the contract and a separate aggregate stop loss providing 80% of coverage in excess of a 100% loss ratio on its crop-hail portfolio. OneBeacon also purchased a new quota share contract on 30% of its MPCI portfolio.
Effective May 1, 2015, OneBeacon renewed its property catastrophe reinsurance program through April 30, 2016. The program provides coverage for OneBeacon's property business as well as certain acts of terrorism. Under the program, the first $20.0 million of losses resulting from any single catastrophe are retained, and 95.0% of the next $10.0 million of losses and 100.0% of the next $100.0 million of losses resulting from the catastrophe are reinsured. The part of the catastrophe loss in excess of $130.0 million would be retained in full. In the event of a catastrophe, OneBeacon's property catastrophe reinsurance program is reinstated for the remainder of the original contract term by paying a reinstatement premium that is based on the percentage of coverage reinstated and the original property catastrophe coverage premium.
Also effective May 1, 2015, OneBeacon lowered its retention on its property-per-risk reinsurance program from $5.0 million to $3.0 million.
Effective June 1, 2015, OneBeacon lowered its retentions on certain casualty and healthcare treaties from $5.0 million to $3.0 million.

Sirius Group
At March 31,June 30, 2015, Sirius Group had $11.610.8 million and $295.3280.3 million of reinsurance recoverables on paid and unpaid losses that will become recoverable if claims are paid in accordance with current reserve estimates. At December 31, 2014, Sirius Group had $11.4 million and $322.2 million of reinsurance recoverables on paid and unpaid losses. Because retrocessional reinsurance contracts do not relieve Sirius Group of its obligation to its insureds, the collectability of balances due from Sirius Group’s reinsurers is important to its financial strength. Sirius Group monitors the financial strength and ratings of retrocessionaires on an ongoing basis. Uncollectible amounts historically have not been significant.
There have been no material changesIn connection with the sale of Sirius Group, White Mountains caused Sirius Group to purchase several industry loss warranty (“ILW”) contracts to augment its overall retrocessional program in order to reduce the risk of loss from major catastrophes subsequent to the signing of the definitive agreement to sell Sirius Group's reinsurance coverage as discussed in Group. (See Note 4 -“Reinsurance” in White Mountains’s 2014 Annual Report on Form 10-K.19 - “Subsequent Events”).

Note 5.  Investment Securities
 
White Mountains’s invested assets consist of securities and other long-term investments held for general investment purposes.  The portfolio of investment securities includes fixed maturity investments, short-term investments, common equity securities, and convertible fixed maturity and preferred investments which are all classified as trading securities. Trading securities are reported at fair value as of the balance sheet date.  Realized and unrealized investment gains and losses on trading securities are reported in pre-tax revenues. White Mountains’s investments in fixed maturity investments are generally valued using industry standard pricing models. Key inputs include benchmark yields, benchmark securities, reported trades, issuer spreads, bids, offers, credit ratings and prepayment speeds.
Income on mortgage-backed and asset-backed securities is recognized using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When actual prepayments differ significantly from anticipated prepayments, the estimated economic life is recalculated and the remaining unamortized premium or discount is amortized prospectively over the remaining economic life.
Realized investment gains and losses resulting from sales of investment securities are accounted for using the specific identification method.  Premiums and discounts on all fixed maturity investments are amortized or accreted to income over the anticipated life of the investment.  Short-term investments consist of money market funds, certificates of deposit and other securities which, at the time of purchase, mature or become available for use within one year.  Short-term investments are carried at amortized or accreted cost, which approximated fair value as of March 31,June 30, 2015 and December 31, 2014.2014.
Other long-term investments consist primarily of hedge funds, private equity funds, surplus note investments, private equity securities and limited liability companies and other investments in limited partnerships.

Certain of the hedge fund investments in which White Mountains is invested are no longer active and are in the process of disposing of their underlying investments. Distributions from such funds are remitted to investors as the fund’s underlying investments are liquidated.  As of March 31,June 30, 2015, distributions of $2.12.0 million were outstanding from these investments. The actual amount of the final distribution remittances remain subject to market fluctuations. The date at which such remittances will be received is not determinable as of March 31,June 30, 2015.
White Mountains has also submitted redemption requests for certain of its investments in active hedge funds.  As of March 31,June 30, 2015, redemptions of $6.910.2 million are outstanding and are subject to market fluctuations. The date at which such redemptions will be received is not determinable as of March 31,June 30, 2015. Redemptions are recorded as receivables when the investment is no longer subject to market fluctuations.
Investments in private equity funds are generally subject to a “lock-up” period during which investors may not request a redemption. Distributions prior to the expected termination date of the fund may be limited to dividends or proceeds arising from the liquidation of the fund’s underlying investments. In addition, certain private equity funds provide an option to extend the lock-up period at either the sole discretion of the fund manager or upon agreement between the fund and the investors.
As of March 31,June 30, 2015, investments in private equity funds were subject to lock-up periods as follows:

Fair value measurements as of March 31,June 30, 2015
White Mountains’s invested assets that are measured at fair value include fixed maturity investments, common equity securities, convertible fixed maturity and preferred investments and other long-term investments, such as interests in hedge funds and private equity funds. Fair value measurements reflect management’s best estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements fallare categorized into a hierarchy with three levelsthat distinguishes between inputs based on market data from independent sources (“observable inputs”) and a reporting entity's internal assumptions based upon the nature of the inputs. Fair value measurements based on quotedbest information available when external market data is limited or unavailable (“unobservable inputs”). Quoted prices in active markets for identical assets are ator liabilities have the top of the hierarchyhighest priority (“Level 1”), followed by fair value measurements based on observable inputs that do not meet the criteria for Level 1, includingother than quoted prices, in inactive markets and quotedincluding prices in active markets for similar but not identical instrumentsassets or liabilities (“Level 2”). Measurements based on and unobservable inputs, including athe reporting entity’sentity's estimates of the assumptions that market participants would use, are athaving the bottom of the hierarchylowest priority (“Level 3”).

White Mountains uses quoted market prices or other observable inputs to determine fair value for the vast majority of its investment portfolio. Investments valued using Level 1 inputs include fixed maturity investments, primarily investments in U.S. Treasuries, common equity securities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs consistare primarily comprised of fixed maturity investments, which have been disaggregated into classes, including corporate debt state and other governmental debt, convertible fixed maturity and preferred securities andissued by corporations, municipal obligations, mortgage and asset-backed securities.securities, foreign government obligations and preferred stocks. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Level 3 fair value estimates based upon unobservable inputs include White Mountains’sMountains's investments in surplus notes, hedge funds and private equity funds, as well as certain investments in certain debtfixed maturity investments, common equity securities, and equity securitiesconvertible fixed and preferred maturity investments where quoted market prices are unavailable. unavailable or are not considered reasonable. White Mountains determines when transfers between levels have occurred as of the beginning of the period.
White Mountains uses brokers and outside pricing services to assist in determining fair values. For investments in active markets, White Mountains uses the quoted market prices provided by outside pricing services to determine fair value. The outside pricing services used by White Mountains uses have indicated that if nothey will only provide prices where observable inputs are available for a security, they willavailable. In circumstances where quoted market prices are unavailable or are not provide a price. In those circumstances,considered reasonable, White Mountains estimates the fair value using industry standard pricing models and observable inputs such as benchmark interest rates, matrix pricing, market comparables, brokeryields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids, offers, credit rating, prepayment speeds, reference data including research publications and other relevant inputs. Given that many fixed maturity investments do not trade on a daily basis, the outside pricing services evaluate a wide range of fixed maturity investments by regularly drawing parallels from recent trades and quotes of comparable securities with similar features. The characteristics used to identify comparable fixed maturity investments vary by asset type and take into account market convention.
White Mountains performs proceduresMountains's process to validateassess the reasonableness of the market prices obtained from the outside pricing sources. Such procedures, which coversources covers substantially all of its fixed maturity investments include,and includes, but areis not limited to, evaluation of model pricing methodologies, and review of the pricing services’services' quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from different independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices and review of assumptions utilized by the pricing service for selected measurements on an ad hoc basis throughout the year. White Mountains also performs back-testing of selected purchases and sales activity to determine whether there are any significant differences between the market price used to value the security prior to purchase or sale and the actual purchase or sale price on an ad-hoc basis throughout the year. Prices provided by the pricing services that vary by more than 5% and $1.0$1.0 million from the expected price based on these procedures are considered outliers. Also considered outliers are prices that haven’t changed from period to period and prices that have trended unusually compared to market conditions. In circumstances where the results of White Mountains’sMountains's review process dodoes not appear to support the market price provided by the pricing services, White Mountains challenges the price. If White Mountains cannot gain satisfactory evidence to support the challenged price, it relies upon its own pricing methodologies to estimate the fair value of the security in question.
The fair valuesvaluation process above is generally applicable to all of such securities are consideredWhite Mountains’s fixed maturity investments. The techniques and inputs specific to be Level 3 measurements.
asset classes within White Mountains’s fixed maturity investments for Level 2 securities that use observable inputs are generally valued using matrixas follow:

Debt securities issued by corporations:The fair value of debt securities issued by corporations is determined from an evaluated pricing model that uses information from market sources and other pricing models.integrates relative credit information, observed market movements, and sector news. Key inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including sector, coupon, credit quality ratings, duration, credit enhancements, early redemption features and market research publications.

19

Municipal obligations: The fair value of municipal obligations is determined from an evaluated pricing model that uses information from market makers, brokers-dealers, buy-side firms, and analysts along with general market information. Key inputs include benchmark yields, reported trades, issuer financial statements, material event notices and new issue data, as well as broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including type, coupon, credit quality ratings, duration, credit enhancements, geographic location and prepayment speeds.  Income on mortgage-backedmarket research publications.

Mortgage and asset-backed securities: The fair value of mortgage and asset-backed securities is recognized usingdetermined from an effective yield based on anticipated prepaymentsevaluated pricing model that uses information from market sources and leveraging similar securities. Key inputs include benchmark yields, reported trades, underlying tranche cash flow data, collateral performance, plus new issue data, as well as broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including issuer, vintage, loan type, collateral attributes, prepayment speeds, default rates, recovery rates, cash flow stress testing, credit quality ratings and market research publications.

Foreign government obligations:The fair value of foreign government obligations is determined from an evaluated pricing model that uses feeds from data sources in each respective country, including active market makers and inter-dealer brokers. Key inputs include benchmark yields, reported trades, broker-dealer quotes, two-sided markets, benchmark securities, bids, offers, local exchange prices, foreign exchange rates and reference data including coupon, credit quality ratings, duration and market research publications.

Preferred stocks: The fair value of preferred stocks is determined from an evaluated pricing model that calculates the estimated economic lifeappropriate spread over a comparable security for each issue. Key inputs include exchange prices (underlying and common stock of same issuer), benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including sector, coupon, credit quality ratings, duration, credit enhancements, early redemption features and market research publications.

Level 3 valuations are generated from techniques that use assumptions not observable in the securities. When actual prepayments differ significantly from anticipated prepayments,market. These unobservable assumptions reflect White Mountains’s assumptions that market participants would use in valuing the estimated economic life is recalculated andinvestment. Generally, certain securities may start out as Level 3 when they are originally issued but as observable inputs become available in the remaining unamortized premium or discount is amortized or accreted prospectively over the remaining economic life.market, they may be reclassified to Level 2.
White Mountains employs a number of procedures to assess the reasonableness of the fair value measurements for its other long-term investments, including obtaining and reviewing the audited annual financial statements of each hedge fund and private equity fund and periodically discussing each fund’s pricing with the fund manager. However, since the fund managers do not provide sufficient information to evaluate the pricing inputs and methods for each underlying investment, the inputs are considered to be unobservable. Accordingly, the fair values of White Mountains’s investments in hedge funds and private equity funds have been classified as Level 3 measurements. The fair value of White Mountains’s investments in hedge funds and private equity funds has been determined using net asset value.
InPrior to the liquidation of the Prospector Offshore Fund, in addition to the investments described above, White Mountains has $38.8 million andhad $38.0 million of investment-related liabilities recorded at fair value and included in other liabilities as ofMarch 31, 2015 and December 31, 2014.  These liabilities relate to securities that have been sold short by limited partnerships in which White Mountains has investments and iswas required to consolidate under GAAP.  These liabilities have a Level 1 designation.

Fair Value Measurements by Level
The following tables summarize White Mountains’s fair value measurements for investments as of March 31,June 30, 2015 and December 31, 2014, by level:major security type and class by level. The major security types were based on the legal form of the securities, with a separate break-out for convertible fixed maturity investments as they may react similar to either debt securities or equity securities, depending on prevailing market conditions. White Mountains has disaggregated its fixed maturity investments based on the issuing entity type, which impacts credit quality, with debt securities issued by U.S. government entities carrying minimal credit risk, while the credit and other risks associated with other issuers, such as corporations, foreign governments, municipalities or entities issuing asset-backed securities vary depending on the nature of the issuing entity type. White Mountains further disaggregates debt securities issued by corporations and equity securities by industry sector because investors often reference commonly used benchmarks and their subsectors to monitor risk and performance. Accordingly, White Mountains has further disaggregated these asset classes into subclasses based on the similar sectors and industry classifications it uses to evaluate investment risk and performance against commonly used benchmarks, such as the Barclays Intermediate Aggregate and S&P 500 indices:

Rollforward of Fair Value Measurements by Level
 White Mountains uses quoted market prices where available as the inputs to estimate fair value for its investments in active markets. Such measurements are considered to be either Level 1 or Level 2 measurements, depending on whether the quoted market price inputs are for identical securities (Level 1) or similar securities (Level 2). Level 3 measurements for fixed maturity investments, common equity securities, convertible fixed maturity and preferred investments and other long-term investments as of March 31,June 30, 2015 and 2014 consist of securities for which the estimated fair value has not been determined based upon quoted market price inputs for identical or similar securities.

These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $5.6$73.9 million for the period March 31,June 30, 2015.
During the first threesix months of 2014, notwo fixed maturity investmentsincome securities classified as Level 3 measurements in the prior
period were recategorized as Level 2 measurements because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at June 30, 2014. These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $19.6 million for the period ended June 30, 2014.
During the first six months of 2014, two fixed income securities which had been classified as a Level 2 measurements in the prior period were recategorized as Level 3 measurements. The securities were priced with unobservable inputs and represent "Transfers out" of Level 2 measurements.and “Transfers in” to Level 3 of $8.5 million for the period ended June 30, 2014. The fair value of these securities was estimated using industry standard pricing methodology, in which management selected inputs using its best judgment. At June 30, 2014, the estimated fair value for these securities determined using the industry standard pricing models was $1.0 million less than the estimated fair value based upon quoted prices provided by a third party pricing vendor.

(1) As of March 31,June 30, 2015, consists of 1 security.
(2) Credit ratings are assigned based on the following hierarchy: 1) Standard and Poor's and 2) Moody’s.
(3) Judgmentally determined based on the Company’s limited trading ability of the issuer.
(4) Stochastic modeling supporting the fair value estimation indicates that the average percentage of discounted payments missed on the seller priority note is roughly equivalent to that of a conventional debt security with a credit rating of ‘B’. The corresponding credit spread increased by an additional 250 bps to reflect both a liquidity discount for a private debt instrument and regulatory payment approval uncertainty, was added to the treasury rate to determine the discount rate for the seller prioritypari passu note.
(5) Stochastic modeling supporting the fair value estimation indicates that the average percentage of discounted payments missed on the pari passu note is roughly equivalent to that of a conventional debt security with a credit rating of ‘CCC’. The corresponding credit spread increased by an additional 250 bps to reflect both a liquidity discount for a private debt instrument and regulatory payment approval uncertainty, was added to the treasury rate to determine the discount rate for the seller priority note.
(6) For estimated value purposes, the assumption has been made that interest payouts begin in year five and principal repayments begin on a graduated basis in year ten for the seller priority note and year fifteen for the pari passu note.
(7) Includes the unrealized gains and losses associated with foreign currency; foreign currency effects based on observable inputs.
(8) Conditional Prepayment Rate (CPR) is an annualized percentage of the existing mortgage pool that is expected to be prepaid in a year.
(9) Constant Default Rate (CDR) is an annualized rate of default of on a pool of mortgage loans, expressed in percentage terms.
(10) Loss severity represents the expected total lifetime losses (both interest and principal losses) as a percentage of the loan principal balance.

The assumed prepayment rate is a significant unobservable input used to estimate the fair value of investments in mortgage backed securities. Generally for bonds priced at a premium, increased in prepayment speeds will result in a lower fair value, while decreases in prepayment speed may result in a higher fair value.


Note 6. Goodwill and Other Intangible Assets

Note 8.  Income Taxes
 
The Company and its Bermuda domiciled subsidiaries are not subject to Bermuda income tax under current Bermuda law. In the event there is a change in the current law such that taxes are imposed, the Company and its Bermuda domiciled subsidiaries would be exempt from such tax until March 31, 2035, pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966. The Company has subsidiaries and branches that operate in various other jurisdictions around the world that are subject to tax in the jurisdictions in which they operate.  The jurisdictions in which the Company’s consolidated subsidiaries and branches are subject to tax are Australia, Belgium, Canada, Denmark, Germany, Gibraltar, Israel, Luxembourg, Malaysia, the Netherlands, Peru, Singapore, Sweden, Switzerland, the United Kingdom and the United States.
White Mountains’s income tax expense related to pre-tax income from continuing operationsbenefit for the three months ended March 31,June 30, 2015 represented an effective tax rate of 46.6%. White Mountains’s income tax expense for the six months ended for June 30, 2015 represented an effective tax rate of 27.5%. White Mountains’s income tax expense for the three and six months ended for June 30, 2014 were 28.8%represented effective tax rates of 22.4% and 27.5%25.0%. The effective tax rate for the three months ended June 30, 2015 was higher than the U.S. statutory rate of 35% primarily due to changes in forecasted earnings by jurisdiction. The effective tax rates for the threesix months ended March 31,June 30, 2015 and the three and six months ended 2014 were lower than the U.S. statutory rate of 35% due to income generated in jurisdictions with lower tax rates than the United States.
In arriving at the effective tax rate for the three and six months ended March 31,June 30, 2015 and 2014, White Mountains forecasted all income and expense items including the change in unrealized investment gains (losses) and realized investment gains (losses) for the years ending December 31, 2015 and 2014.
White Mountains records a valuation allowance against deferred tax assets if it becomes more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in income tax expense in the period of change. In determining whether or not a valuation allowance, or change therein, is warranted, White Mountains considers factors such as prior earnings history, expected future earnings, carryback and carryforward periods and strategies that if executed would result in the realization of a deferred tax asset.  It is possible that certain planning strategies or projected earnings in certain subsidiaries may not be feasible to utilize the entire deferred tax asset, which could result in material changes to White Mountains’s deferred tax assets and tax expense.
White Mountains is no longer subject to U.S. federal or state tax examinations by tax authorities for years before 2007. With few exceptions, White Mountains is no longer subject to non-U.S. income tax examinations by tax authorities for years before 2005.

On July 28, 2011, the IRS commenced an examination of the income tax returns for 2007, 2008 and 2009 for certain U.S. subsidiaries of OneBeacon.  On July 17, 2013, OneBeacon received a revised Form 4549-A (Income Tax Discrepancy Adjustments) from the IRS relating to the examination of tax years 2007, 2008 and 2009. The estimated total assessment, including interest, utilization of alternative minimum and foreign tax credit carryovers and capital loss carrybacks, is $73.874.8 million. However, $60.2 million of the proposed adjustments relate to items for which the expense deduction has been disallowed in a year being examined, but ultimate deductibility is highly certain to occur in a later period. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of these deductions in the exam period would not affect the effective tax rate, but would accelerate the payment of cash to the taxing authority. White Mountains disagrees with the adjustments proposed by the IRS and is defending its position. Although the timing of the resolution of these issues is uncertain, it is reasonably possible that the resolution could occur within the next twelve months. An estimate of the range of potential outcomes cannot be made at this time. White Mountains does not expect the resolution of this examination to result in a material adverse change to its financial position.position results of operations and cash flows.
On September 5, 2013, the IRS commenced an examination of the income tax returns for 2010, 2011 and 2012 for certain U.S. subsidiaries of OneBeacon. White Mountains does not expect the resolution of this examination to result in a material change to its financial position.position, results of operations and cash flows.
On December 18, 2014, the IRS commenced an examination of the 2012 income tax return for Guilford Holdings, Inc. and
subsidiaries. White Mountains does not expect the resolution of this examination to result in a material change to its financial position, results of operations and cash flows.

Variable Annuity Reinsurance
White Mountains has entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan. At March 31,June 30, 2015 and December 31, 2014, the total guarantee value was approximately ¥117.8100.7 billion (approximately $1.00.8 billion at exchange rates on that date) and ¥134.2 billion (approximately $1.1 billion at exchange rates on that date), respectively. The collective account values of the underlying variable annuities were approximately 113% of the guarantee value at both March 31,June 30, 2015 and December 31, 2014.  During the second quarter of 2015, the variable annuity contracts reinsured by WM Life Re began to mature.  WMLife Re is in runoff, andan all of its contracts will mature by June 30, 2016.
The following table summarizes the pre-tax operating results of WM Life Re for the three and six months ended March 31,June 30, 2015 and 2014.

Collateral in the form of fixed maturity securities consists of Government of Japan Bonds, which are recorded at fair value. Collateral in the form of short-term investments consists of money-market instruments, carried at amortized cost, which approximates fair value. 
All of White Mountains’s variable annuity reinsurance liabilities were classified as Level 3 measurements at March 31,June 30, 2015 and 2014. The fair value of White Mountains’s variable annuity reinsurance liabilities are estimated using actuarial and capital market assumptions related to the projected discounted cash flows over the term of the reinsurance agreement. Actuarial assumptions regarding future policyholder behavior, including surrender and lapse rates, are generally unobservable inputs and significantly impact the fair value estimates. Market conditions including, but not limited to, changes in interest rates, equity indices, market volatility and foreign currency exchange rates as well as the variations in actuarial assumptions regarding policyholder behavior may result in significant fluctuations in the fair value estimates. Generally, the liabilities associated with these guarantees increase with declines in the equity markets, interest rates and currencies against the Japanese yen, as well as with increases in market volatilities. White Mountains uses derivative instruments, including put options, interest rate swaps, total return swaps on bond and equity indices and forwards and futures contracts on major equity indices, currency pairs and government bonds, to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. The types of inputs used to estimate the fair value of these derivative instruments, with the exception of actuarial assumptions regarding policyholder behavior and risk margins, are generally the same as those used to estimate the fair value of variable annuity liabilities.
The following summarizes quantitative information about significant unobservable inputs associated with the fair value estimates for variable annuity reinsurance liabilities and derivative instruments that have been classified as Level 3 measurements:

WM Life Re enters into both over-the-counter (“OTC”) and exchange traded derivative instruments to economically hedge the liability from the variable annuity benefit guarantee.  In the case of OTC derivatives, WM Life Re has exposure to credit risk for amounts that are uncollateralized by counterparties. WM Life Re’s internal risk management guidelines establish net counterparty exposure thresholds that take into account OTC counterparties’ credit ratings. The OTC derivative contracts are subject to restrictions on liquidation of the instruments and distribution of proceeds under collateral agreements.

In the case of exchange traded instruments, WM Life Re has exposure to credit risk for amounts uncollateralized by margin balances. WM Life Re has entered into master netting agreements with certain of its counterparties whereby the collateral provided (held) is calculated on a net basis. The following summarizes amounts offset under master netting agreements:

Forward Contracts
White Mountains has entered into currency forward contracts at Sirius Group. White Mountains monitors its exposure to foreign currency and adjusts its forward positions within the risk guidelines and ranges established by senior management for each currency, as necessary. While White Mountains actively manages its forward positions, mismatches between movements in foreign currency rates and its forward contracts may result in currency positions being outside the pre-defined ranges and/or foreign currency losses. At March 31,June 30, 2015, White Mountains held approximately $56.531.9 million (SEK 489.3262.7 million) total gross notional value of foreign currency forward contracts.
All of White Mountains’s forward contracts are traded over-the-counter. The fair value of the contracts has been estimated using OTC quotes for similar instruments and accordingly, the measurements have been classified as Level 2 measurements at March 31,June 30, 2015.
The net realized and unrealized derivative losses recognized in net realized and unrealized investment gains (losses) for both the three and six months ended June 30, 2015 was $0.4 million. The net realized and unrealized derivative losses recognized in net realized and unrealized investment gains (losses) for the three and six months ended March 31, 2015 andJune 30, 2014 were $0.0was break-even million and $(0.1) million.
All of White Mountains’s forward contracts are subject to master netting agreements. As of March 31,June 30, 2015 and December 31, 2014, the gross liability amount offset under master netting arrangements and the net amount recognized in other investments approximately offset each other.

Interest Rate Cap
In May 2007, Sirius International Group, Ltd. (“SIG”), an intermediate holding company of Sirius Group, issued the SIG Preference Shares, with an initial fixed annual dividend rate of 7.506%. In June 2017, the fixed rate will move to a floating rate equal to the greater of (i) 7.506% and (ii) 3-month LIBOR plus 320 basis points. In July 2013, SIG executed the Interest Rate Cap for the period from June 2017 to June 2022 to protect against a significant increase in interest rates during that 5-year period. The Interest Rate Cap economically fixes the annual dividend rate on the SIG Preference Shares from June 2017 to June 2022 at 8.30%. The cost of the Interest Rate Cap was an upfront premium of 395 basis points of the $250.0 million notional value, or approximately $9.9 million for the full notional amount.
The Interest Rate Cap does not qualify for hedge accounting. It is recorded in other assets at fair value. Changes in fair value are recognized within other revenue. Collateral held is recorded within short-term investments with an equal amount recognized as a liability to return collateral. The fair value of the Interest Rate Cap has been estimated using a single broker quote and accordingly, has been classified as a Level 3 measurement at March 31,June 30, 2015.
The following tables summarize the changes in the fair value of the Interest Rate Cap for the three and six months ended March 31,June 30, 2015 and 2014:

Weather Derivatives
For the three and six months ended March 31,June 30, 2015, Sirius Group recognized $2.3 million and $3.1 million of net gains on its weather and weather contingent derivatives portfolio. For the three and six months ended June 30, 2014, Sirius Group recognized $0.8$1.0 million and $0.4$0.6 million of net gainslosses on its weather and weather contingent derivatives portfolio. The fair values of the assumed contracts are subject to change in the near-term and reflect management’s best estimate based on various factors including, but not limited to, observed and forecasted weather conditions, changes in interest or foreign currency exchange rates and other market factors. Estimating the fair value of derivative instruments that do not have quoted market prices requires management’s judgment in determining amounts that could reasonably be expected to be received from or paid to a third party to settle the contracts. Such amounts could be materially different from the amounts that might be realized in an actual transaction to settle the contract with a third party. Because of the significance of the unobservable inputs used to estimate the fair value of Sirius Group’s weather risk contracts, the fair value measurements of the contracts are deemed to be Level 3 measurements in the fair value hierarchy.

Tranzact Interest Rate Swap
Tranzact has a $70.0 million term loan facility that carries a variable rate equal to the U.S. dollar LIBOR rate, plus an applicable margin. At March 31,June 30, 2015, the variable interest rate on the term loan was 4.172%4.185%, including a margin over LIBOR of 4.0%. Effective October 10, 2014, to effectively fix the rate it pays on this term loan, Tranzact entered into an interest rate swap agreement with a notional amount of $70.0 million at inception, which decreases over the term of the swap by amounts equivalent to scheduled principal repayments made on Tranzact’s term loan. As of March 31,June 30, 2015, the notional amount was $67.4$66.1 million. Under the terms of the swap agreement, Tranzact pays a fixed rate of 1.34% and receives a variable rate, which is reset monthly, based on the then-current U.S. dollar LIBOR rate. The variable rate received by Tranzact under the swap agreement was 0.1518% at inception and 0.178%0.1866% at March 31,June 30, 2015. The total current effective rate on Tranzact's debt was 5.3%5.5% at March 31,June 30, 2015.
The swap is measured at fair value with changes therein recognized within other revenues and is accounted for as a non-hedge derivative instrument. As of March 31,June 30, 2015, the estimated fair value of the swap was $(0.5)$(0.2) million. There are no collateral arrangements associated with the swap.

Foreign Currency Swap
On April 28, 2015, White Mountains executed two foreign currency swaps, each with a notional amount of $50.0 million, maturing on March 20, 2017. Under the first swap, White Mountains pays Swedish krona and receives U.S. dollars. Under the second swap, White Mountains pays Euro and receives U.S. dollars. The swaps, which were executed as part of White Mountains's management of overall foreign currency exposure at Sirius Group, have not been designated or accounted for under hedge accounting. At June 30, 2015, the fair value of the swaps of $(2.7) million was recorded within other assets. Changes in fair value are recognized as unrealized gains or losses and are presented within other revenues. White Mountains does not provide or hold any collateral associated with the swaps.

Note 10. Municipal Bond Guarantee Insurance

In 2012, HG Global was capitalized with $594.5 million from White Mountains and $14.5 million from non-controlling interests to fund BAM, a newly formed mutual municipal bond insurer. As of March 31,June 30, 2015, White Mountains owned 96.9% of HG Global’s preferred equity and 88.4% of its common equity. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503.0 million of BAM surplus notes. Through HG Re, which had statutory capital of $453.0454.6 million at March 31,June 30, 2015, HG Global provides first loss reinsurance protection for policies underwritten by BAM of up to 15% of par outstanding, on a per policy basis. HG Re’s obligations to BAM are collateralized in trusts, and there is an aggregate loss limit that is equal to the total assets in the collateral trusts at any point in time.
For the three and six months ended March 31,June 30, 2015, HG Global had pre-tax income of $3.1 million and$8.6 million, which included $3.9 million and $7.9 million of interest income on the BAM surplus notes. For the three and six months ended June 30, 2014, HG Global had pre-tax income of $5.4$5.0 million and $4.6$9.6 million,, which included $4.0 million and $3.9$7.9 million of interest income on the BAM surplus notes.
For the three and six months ended March 31,June 30, 2015 and 2014,, White Mountains reported pre-tax losses of $8.714.1 million and $8.622.9 million on BAM that were recorded in net loss attributable to non-controlling interests, which included $4.03.9 million and $3.97.9 million of interest expense on the BAM surplus notes. For the three and six months ended June 30, 2014, White Mountains reported pre-tax losses of $8.0 million and $16.6 million on BAM that were recorded in net loss attributable to non-controlling interests, which included $4.0 million and $7.9 million of interest expense on the BAM surplus notes.
Effective January 1, 2014, HG Global and BAM agreed to change the interest rate on the BAM surplus notes for the five years ending December 31, 2018 from a fixed rate of 8% to a variable rate equal to the one-year U.S. treasury rate plus 300 basis points, set annually, which is 3.15% and 3.13% for 2015 and 2014. Prior to the end of 2018, BAM has the option to extend the variable rate period for an additional three years.  At the end of the variable rate period, the interest rate will be fixed at the higher of the then current variable rate or 8%. BAM is required to seek regulatory approval to pay interest and principal on its surplus notes only when adequate capital resources have accumulated beyond BAM’s initial capitalization and a level that continues to support its outstanding obligations, business plan and ratings.
All of the contracts issued by BAM are accounted for as insurance contracts under ASC 944-605, Financial Guarantee Insurance Contracts. Premiums are received upfront and an unearned premium revenue liability, equal to the amount of the cash received, is established at contract inception. Premium revenues are recognized in revenue over the period of the contracts in proportion to the amount of insurance protection provided using a constant rate. The constant rate is calculated based on the relationship between the par outstanding in a given reporting period compared with the sum of each of the par amounts outstanding for all periods.
The following table provides a schedule of BAM’s insured obligations:

Symetra
On June 30, 2015, pursuant to the redemption of White Mountains's investments in the Prospector Funds, 513,500 common shares of Symetra were distributed to White Mountains. At March 31,June 30, 2015 and December 31, 2014, White Mountains owned 20.05 million20,562,379 and 20,048,879 common shares of Symetra Financial Corporation (“Symetra”), a 17.27%17.71% and 17.31% common share ownership. White Mountains accounts for its investment in common shares of Symetra using the equity method. During the three and six months ended March 31,June 30, 2015 and 2014,, White Mountains received cash dividends from Symetra of $2.2 million and $2.04.4 million on its common share investment that were recorded as a reduction of White Mountains’s investment in Symetra. During the three and six months ended June 30, 2014, White Mountains received cash dividends from Symetra of $2.0 million and $4.0 million.

3542

As of December 31, 2011, White Mountains concluded that its investment in Symetra common shares was other-than-temporarily impaired and wrote down the GAAP book value of the investment to its estimated fair value of $261.0 million or $15 per share.  This impairment, as well as the effect of Symetra capital transactions, has resulted in a basis difference between the GAAP carrying value of White Mountains’s investment in Symetra common shares and the amount derived by multiplying the percentage of White Mountains common share ownership by Symetra’s total GAAP equity. As of March 31,June 30, 2015, the pre-tax unamortized basis difference was $165.7$164.1 million, of which $35.1$33.0 million is attributable to equity in earnings of unconsolidated affiliates and $130.6$131.1 million is attributable to equity in net unrealized gains of unconsolidated affiliates. As of December 31, 2014, the pre-tax unamortized basis difference was $170.4 million, of which $36.4 million is attributable to equity in earnings of unconsolidated affiliates and $134.0 million is attributable to equity in net unrealized gains of unconsolidated affiliates.
The pre-tax basis difference is being amortized over a 30-year period with a weighted average of 28-years remaining. The amortization is based on estimated future cash flows associated with Symetra’s underlying assets and liabilities to which the basis differences have been attributed. White Mountains continues to record its equity in Symetra's earnings and net unrealized gains (losses). In addition, White Mountains recognizes the amortization of the basis difference through equity in earnings of unconsolidated affiliates and equity in net unrealized gains (losses) from investments in unconsolidated affiliates consistent with the original attribution of the basis differences between equity in earnings and equity in net unrealized gains (losses). For the three and six months ended March 31,June 30, 2015, White Mountains recognized after-tax amortization of $0.7 million and$1.4 million through equity in earnings of unconsolidated affiliates and $2.7 million and $5.5 million through equity in net unrealized gains from investments in unconsolidated affiliates. For the three and six months ended June 30, 2014, White Mountains recognized after-tax amortization of $0.7 million and $0.7$1.4 million through equity in earnings of unconsolidated affiliates and $2.8$2.9 million and $2.9$5.8 million through equity in net unrealized gains from investments in unconsolidated affiliates.

Note 17. Discontinued Operations
 
For the three months ended March 31,June 30, 2015,, White Mountains recorded a net loss from sale of discontinued operations of $0.1 million, which was primarily related to a tax payment of $0.3 million to Allstate pursuant to the Esurance sale and post-closing expenses incurred in connection with the Runoff Business, offset by a $0.3 million gain related to an adjustment to the estimated loss on sale from the Runoff Transaction, which includes the final settlement of certain post-closing items. The six months ended June 30, 2015 also included a net gain from sale of discontinued operations of $8.0 million, which is primarily related to the favorable loss reserve development on loss reserves transferred in the sale of Esurance and Answer Financial. See “Esurance” in Note 18.
For both the three and six months ended March 31, 2015 andJune 30, 2014, White Mountains recorded a net loss on discontinued operation of $0.1 million and $0.5 million. The loss from discontinued operations, net of tax, of $0.1 million for the three months ended March 31, 2015, was the result of post-closing expenses incurred in connection with the Runoff Business. The loss from discontinued operations, net of tax, of $0.5 million for the three months ended March 31, 2014, was primarily due to non-claims expenses related to the Runoff Business, including dedicated staff.
The lossgain from sale of discontinued operations relatedof $2.7 million, primarily due to an interim payment on the favorable development on loss reserves transferred with the sale of Esurance and Answer Financial. The gain from sale of discontinued operations for both the three and six months ended June 30, 2014 also included two offsetting amounts at OneBeacon. First, OneBeacon reduced its estimate of the fair value of the surplus notes expected to be issued at the closing of the Runoff Transaction based on their internal valuation model which, as of June 30, 2014, was $8.2 million, pre-tax, ($5.3 million, after tax) less than par value of the surplus notes, resulting in a corresponding increase to the Runoff Business is subject to post-closing adjustments related to the true-up of the final closing balance sheet. Armour has presented its proposed final closing deliverables pursuant toestimated loss on sale. Second, the stock purchase agreement andwas revised during the second quarter of 2014 in part to increase the cap on seller financing, which resulted in OneBeacon is inrecording a $7.4 million reserve charge ($4.8 million after tax) as a reduction to the processestimated loss on sale of reviewing and responding.discontinued operations.

Earnings Per Share
Basic earnings per share amounts are based on the weighted average number of common shares outstanding including unvested restricted shares that are considered participating securities.  Diluted earnings per share amounts are based on the weighted average number of common shares including unvested restricted shares and the net effect of potentially dilutive common shares outstanding. The following table outlines the computation of earnings per share for discontinued operations for the three and six months ended March 31,June 30, 2015 and 2014:

Note 18. Contingencies

Legal Contingencies
White Mountains, and the insurance and reinsurance industry in general, are routinely subject to claims related litigation and arbitration in the normal course of business, as well as litigation and arbitration that do not arise from, or are directly related to, claims activity. White Mountains’s estimates of the costs of settling matters routinely encountered in claims activity are reflected in the reserves for unpaid loss and LAE. See(See Note 3 - “Loss and Loss Adjustment Expense Reserves”).
White Mountains considers the requirements of ASC 450 when evaluating its exposure to non-claims related litigation and arbitration. ASC 450 requires that accruals be established for litigation and arbitration if it is probable that a loss has been incurred and it can be reasonably estimated. ASC 450 also requires that litigation and arbitration be disclosed if it is probable that a loss has been incurred or if there is a reasonable possibility that a loss may have been incurred.
Although the ultimate outcome of claims and non-claims related litigation and arbitration, and the amount or range of potential loss at any particular time, is often inherently uncertain, management does not believe that the ultimate outcome of such claims and non-claims related litigation and arbitration will have a material adverse effect on White Mountains’s financial condition, results of operations or cash flows.

4148

The following summarizes significant legal contingencies, ongoing non-claims related litigation or arbitration as of March 31,June 30, 2015:

Esurance
On October 7, 2011, the Company completed the sale of its Esurance and Answer Financial subsidiaries (the “Transferred Subsidiaries”) to The Allstate Corporation (“Allstate”) pursuant to a Stock Purchase Agreement dated as of May 17, 2011 (filed as an exhibit to the Company’s current report on Form 8-K on May 18, 2011, the “Agreement”).  The Company has certain contingencies under the Agreement as follows:  (i) subjectSubject to specified thresholds and limits, the Company generally indemnifies Allstate for breaches of its representations and warranties in the Agreement for a period of eighteen months (although longer for specified representations and warranties) from the closing, (ii) the Company indemnifies Allstate for breaches of certain covenants in the Agreement, including certain agreements by the Company notremains contingently liable to solicit certain employees of the Transferred Subsidiaries for three years after the closing, and (iii) subject to specified thresholds and limits, the Company indemnifies Allstate for specified matters related to the pre-closing period, including (a) specified litigation matters, (b) losses of the Transferred Subsidiaries arising from extra-contractual claims and claims in excess of policy limits (“ECO/EPL losses”), (c) certain corporate reorganizations effected to remove entities from the Transferred Subsidiaries that were not being sold in the transaction, and (d) certain tax matters, including certain net operating losses being less than stated levels.  In addition, the Company retains 90% of positive or negative development in the loss reserves of the Transferred Subsidiaries as of the closing date (net of ECO/EPL losses) through December 31, 2014. During2014 (the “Reserve Settlement”).  The transferred loss reserves have developed favorably since the first quarter of 2015,closing and, as a result, Allstate informedhas made payments to the Company that they owein the two annual interim settlements since closing.  For the third (and final) reserve settlement, Allstate believes it owes approximately $8.0 million to the Company for favorable development in the transferred loss reserves, which the Company has recorded as a gain from sale of discontinued operations.operations in the first quarter of 2015.  The amountCompany believes that it is notowed approximately $18.0 million for the final settlement, and is being reviewed by the Company.parties have commenced the process of arbitrating the dispute.

Runoff Transaction
Subsequent to the closing of the Runoff Transaction, on January 22, 2015, three holders of insurance policies issued by the companies OneBeacon sold to Armour filed a Petition for Review with the Commonwealth Court of Pennsylvania (“Commonwealth Court”) requesting that the Commonwealth Court vacate the Pennsylvania Insurance Department’s (“PID”) orders approving the Runoff Transaction and denying their right to intervene in the PID’s regulatory review of the Runoff Transaction. White Mountains believes the claims made by the petitioners are without merit and has intervened in the proceedings before the Commonwealth Court to vigorously defend the propriety of the PID’s orders in their entirety. White Mountains believes that the possibility is remote that these proceedings could result in an adverse outcome or have a material financial impact on the Company��sCompany’s results of operations or financial position in the future.

Tribune Company
In June 2011, Deutsche Bank Trust Company Americas, Law Debenture Company of New York and Wilmington Trust Company (collectively referred to as “Plaintiffs”), in their capacity as trustees for certain senior notes issued by the Tribune Company (“Tribune”), filed lawsuits in various jurisdictions (the “Noteholder Actions”) against numerous defendants including OneBeacon, OneBeacon-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune seeking recovery of the proceeds from the sale of common stock of Tribune in connection with Tribune's leveraged buyout in 2007 (the “LBO”). Tribune filed for bankruptcy in 2008 in the Delaware bankruptcy court (the “Bankruptcy Court”). The Bankruptcy Court granted Plaintiffs permission to commence these LBO-related actions, and in 2011, the Judicial Panel on Multidistrict Litigation granted a motion to consolidate the actions for pretrial matters and transferred all such proceedings to the United States District Court for the Southern District of New York. Plaintiffs seek recovery of the proceeds received by the former Tribune shareholders on a theory of constructive fraudulent transfer asserting that Tribune purchased or repurchased its common shares without receiving fair consideration at a time when it was, or as a result of the purchases of shares, was rendered, insolvent. OneBeacon has entered into a joint defense agreement with other affiliates of White Mountains that are defendants in the action. Certain subsidiaries of White Mountains received approximately $39.0 million for Tribune common stock tendered in connection with the LBO.
The Court granted an omnibus motion to dismiss the Noteholder Actions in September 2013 and Plaintiffs appeal is pending.
   ��    In addition, OneBeacon, OneBeacon-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune, along with thousands of former Tribune shareholders, have been named as defendants in an adversary proceeding brought by the Official Committee of Unsecured Creditors of the Tribune Company (the “Committee”), on behalf of the Tribune Company, which seeks to avoid the repurchase of shares by Tribune in the LBO on a theory of intentional fraudulent transfer (the “Committee Action”). Tribune emerged from bankruptcy in 2012, and a litigation trustee replaced the Committee as plaintiff in the Committee Action. This matter was consolidated for pretrial matters with the Noteholder Actions in the United States District Court for the Southern District of New York and was stayed pending the motion to dismiss in the Noteholder Action. An omnibus motion to dismiss the shareholder defendants in the Committee Action was filed in May 2014. No amount has been accrued in connection with this matter as of March 31,June 30, 2015, as the amount of loss, if any, cannot be reasonably estimated.

Note 19. Subsequent Events

Sale of Sirius Group
On July 27, 2015, White Mountains announced it signed a definitive agreement to sell Sirius Group to CM International Holding PTE Ltd., the Singapore-based investment arm of China Minsheng Investment Corp., Ltd. (“CMI”). The purchase price will be paid in cash in an amount equal to 127.3% of Sirius’s closing date tangible common shareholder’s equity plus $10.0 million. Based on Sirius's tangible common shareholder's equity at December 31, 2014, the purchase price would be $2.2 billion. White Mountains has the option to replenish Sirius’s tangible common shareholder’s equity to its December 31, 2014 level should it be below that level at closing. The transaction is expected to close within six months. It is subject to regulatory approval and other customary closing conditions.
In connection with the transaction, White Mountains caused Sirius Group to purchase several industry loss warranty (“ILW”) contracts to augment its overall retrocessional program in order to reduce the risk of loss from major catastrophes subsequent to the signing of the definitive agreement to sell Sirius Group.  The cost and potential economic benefit provided by the coverage under the ILWs inures to White Mountains. The majority of the contracts expire in May or June of 2016. The following summarizes the ILW contracts in force:
ScopeLimitIndustry Loss Trigger
United States first event$75.0 million$40.0 billion
United States first event$22.5 million$50.0 billion
United States second event$45.0 million$15.0 billion
Japan first event$25.0 million$12.5 billion

OneBeacon Crop Business
On July 31, 2015, OneBeacon exited its multiple peril crop insurance (“MPCI”) and its related crop-hail businesses (collectively, “Crop Business”), due to the sale of its exclusive partner, Climate Crop Insurance Agency, to an affiliate of AmTrust Financial Services (“AmTrust”). As a result of the sale, OneBeacon and Climate Crop Insurance Agency agreed to terminate the existing 5 year agreement early and OneBeacon received a payment of $3.0 million in consideration. Also related to the sale, OneBeacon has withdrawn its 2016 Plan of Operations from the Federal Crop Insurance Corporation, which previously authorized it to write MPCI for the 2016 Reinsurance Year (July 1, 2015 to June 30, 2016) and affiliates of AmTrust will reinsure OneBeacon's remaining net Crop Business exposure for the 2015 reinsurance year (July 1, 2014 to June 30, 2015) under related 100% quota share reinsurance agreements. During the six months ended June 30, 2015, OneBeacon recorded net written premiums related to the Crop business of $26.6 million and a net pre-tax underwriting loss $1.3 million (excluding allocated other underwriting expenses of $1.5 million). During the year ended December 31, 2014, OneBeacon recorded net written premiums related to the Crop business of $35.1 million and a net pre-tax underwriting loss of $3.5 million (excluding allocated other underwriting expenses of $1.0 million).

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations.
 
The following discussion contains “forward-looking statements”. White Mountains intends statements that are not historical in nature, which are hereby identified as forward-looking statements, to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. White Mountains cannot promise that its expectations in such forward-looking statements will turn out to be correct. White Mountains’s actual results could be materially different from and worse than its expectations. See “FORWARD-LOOKING STATEMENTS” for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.
The following discussion also includes three non-GAAP financial measures - adjusted comprehensive income (loss), adjusted book value per share and total adjusted capital - that have been reconciled to their most comparable GAAP financial measures (see page 68)79). White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains’s financial performance and condition.

RESULTS OF OPERATIONS FOR THE THREE AND SIX MONTHS ENDED MARCH 31,JUNE 30, 2015 AND 2014

Overview
White Mountains ended the firstsecond quarter of 2015 with an adjusted book value per share of $664, flat$671, an increase of 1% for both the second quarter and first six months of 2015, including dividends. Foreign currency losses of $8 per share offset solid underwriting and decent investment returns in local currencies. White Mountains reported adjusted comprehensive lossincome of $3$49 million and $45 million for the second quarter and first quartersix months of 2015 compared to adjusted comprehensive income of $88$68 million and $155 million for the second quarter and first quartersix months of 2014.
On July 27, 2015, White Mountains announced it signed a definitive agreement to sell Sirius Group to CM International Holding PTE Ltd., the Singapore-based investment arm of China Minsheng Investment Corp., Ltd. (“CMI”). The purchase price will be paid in cash in an amount equal to 127.3% of Sirius’s closing date tangible common shareholder’s equity plus $10 million. Based on Sirius's tangible common shareholder's equity at December 31, 2014, the purchase price would be $2.2 billion. White Mountains has the option to replenish Sirius’s tangible common shareholder’s equity to its December 31, 2014 level should it be below that level at closing. White Mountains expects that the transaction will increase its adjusted book value by approximately $65 per share, which is subject to Sirius's interim results through closing and reflects transaction costs and compensation accruals, net of any applicable tax effects. The transaction is expected to close within six months. It is subject to regulatory approval and other customary closing conditions. See “Note 19 - Subsequent Events”.
OneBeacon’s book value per share increased 2.3%0.5% for the second quarter and 2.8% for the first quartersix months of 2015, including dividends. OneBeacon’s GAAP combined ratio was 95% for the firstsecond quarter of 2015 compared to 89%99% for the second quarter of last year, while the GAAP combined ratio was 95% for the first six months of 2015 compared to 94% for the first six months of last year. Catastrophe losses added 2 points to the combined ratios for both the second quarter and first six months of 2015, primarily related to severe spring weather in the Midwest and Southern United States, as well as winter storms in the Northeast United States in the first quarter, compared to 1 point of catastrophe losses in both the second quarter and first six months of last year. Net loss reserve development did not have a meaningful impact on the second quarter or first six months of 2015, compared to unfavorable loss reserve development of 3 points and 1 point for the second quarter and first six months of last year.
Sirius Group’s GAAP combined ratio was 78% for the second quarter of 2014.2015 compared to 81% for the second quarter of last year, while the GAAP combined ratio was 79% for the first six months of 2015 compared to 77% for the first six months of last year. The firstcombined ratios for the 2015 periods benefited from lower catastrophe losses compared to the 2014 periods. The second quarter of 2015 included 2 points of catastrophe losses, primarily related tofrom winter storms in the Northeast United States, compared to 1 point6 points of catastrophe losses in the priorsecond quarter of last year. Additionally, the expense ratio was higher byThe first six months of 2015 included 2 points asof catastrophe losses compared to 3 points in the prior period included the beneficial impactfirst six months of the transition services agreement associated with the sale of OneBeacon's personal lines business, whichlast year. Favorable loss reserve development was terminated after5 points and 3 points in the second quarter last year. Separation costs from management restructuring incurredand first six months of 2015 and was primarily due to reductions in prior year catastrophes and run-off casualty business, compared to 3 points and 4 points in the second quarter and first quarter of 2015 also contributed to the increase in the expense ratio.
Sirius Group’s GAAP combined ratio was 81% for the first quarter of 2015 compared to 73% for the first quartersix months of 2014. The increase was driven by lower favorable loss reserve development and change in business mix. Catastrophe losses did not meaningfully impact the combined ratio in either period.
White Mountains’s total net written premiums increased 5% to $514 million in the second quarter of 2015 and decreased 8%2% to $599$1,112 million in the first quartersix months of 2015. OneBeacon’s net written premiums decreased 8%increased 9% to $287$321 million in the second quarter and were flat for the first quartersix months of 2015 at $608 million. The increase in net written premiums for the second quarter at OneBeacon was primarily driven by OneBeacon’s decision to exit itsgrowth in OneBeacon's newer lines, particularly OneBeacon Program Group. For the first six months of 2015, increases in OneBeacon's newer lines, particularly OneBeacon Program Group and OneBeacon Surety Group, were substantially offset by the absence of lawyers liability business in December($18 million), which OneBeacon exited at the end of 2014, and a change in the timingtermination of recognizingan affiliated reinsurance treaty ($12 million). Excluding the impact of these items, OneBeacon's net written premiums in its spring crop business, whilegrew by 5% for the first six months of 2015. Sirius Group’s net written premiums decreased 9% (5%1% (flat in local currencies) to $303$184 million, driven by a decreaseand 6% (3% in property businesslocal currencies) to $488 million in the second quarter and first six months of 2015, primarily reflecting increased retrocessional purchases.purchases on property lines.

Net investment income decreased 20% in the quarter to $24 million, primarily due to lower average coupon rates on fixed maturity investments and lower dividend income on common equity securities.  Earned insurance and reinsurance premiums increased 7% to $537.3 million, driven by a 10% increase at OneBeacon. Other revenue increased to $36$88 million in the firstsecond quarter of 2015 from a loss of $3$6 million in the firstsecond quarter of 2014. Other revenue in the firstsecond quarter of 2015 includes $38$35 million from Tranzact and $30$23 million from MediaAlpha neither of which were includedcompared to $20 million from MediaAlpha in the firstsecond quarter of 2014.

Consolidated Results - Six Months Ended June 30, 2015 versus Six Months Ended June 30, 2014
White Mountains’s total revenues increased 1% to $1,244 million in the first six months of 2015, which was driven by other revenues from Tranzact and MediaAlpha, higher earned premiums and a gain from the sale of Hamer LLC, mostly offset by lower net realized and unrealized investment gains.  Earned insurance and reinsurance premiums increased 3% to $1,032 million.  Net investment income decreased 13% to $47 million, primarily due to lower dividend income on common equity securities and lower average coupon rates on fixed maturity investments.
White Mountains reported net realized and unrealized investment gains of $42 million in the first six months of 2015, which included $49 million of net realized and unrealized foreign currency gains on investments, compared to $178 million of net realized and unrealized investment gains in the first six months of 2014, which included $44 million of net realized and unrealized foreign currency gains.

OneBeacon Results—Three Months EndedJune 30, 2015 versus Three Months EndedJune 30, 2014
OneBeacon's GAAP combined ratio was 95% for the firstsecond quarter of 2015 compared to 89%99% for the firstsecond quarter of 2014. The increasedecrease was partiallyprimarily driven by a higher current accident yearno net loss ratio.reserve development in the second quarter of 2015 compared to 3 points of unfavorable loss reserve development in the second quarter of 2014. The firstsecond quarter of 2015 also included 2 points of catastrophe losses, primarily related to winter stormswind and thunderstorms in the NortheastMidwest and Southern United States, compared to 1 point of catastrophe losses in the firstsecond quarter of 2014. There was one point of favorable loss reserve development in each period. Additionally, the expense ratio was higher by 2 points, primarily driven by the prior period benefiting from a transition services agreement with the buyer of OneBeacon's legacy personal lines business, which was terminated on June 30, 2014, and separation costs from management restructuring incurred in the first quarter of 2015.

OneBeacon’s net income for the three months ended March 31, 2015second quarter was also adversely impacted by a $4$2 million negative adjustment to the pre-tax gain on the salewrite-off of Essentia Insurance Company (Essentia). OneBeacon previously recognizedcapitalized software recorded as a pre-tax gain of $23 million on its sale of Essentia, an indirect wholly-owned subsidiary which wrote legacy collector cars and boats business, to Markel Corporation during the first quarter of 2013. During the first quarter of 2015, OneBeacon recognized the loss of $4 million in other revenues in connection with an assessment from the Michigan Catastrophic Claims Association payable to Markel Corporation pursuant to the indemnification provisions in the stock purchase agreement governing the sale of Essentia.revenues.
Net written premiums were $287 millionincreased 9% in the firstsecond quarter of 2015 a decrease of 8% from the first quarter last year, butto $321 million, primarily due to an increase of 2% for ongoing businesses. The 8% decrease reflects the exit from lawyers liability businessOneBeacon Program Group ($1021 million), the termination of an affiliated reinsurance treaty ($7 million), and the implementation of an earlier cutoff date for recording spring crop premiums that resulted in more net written premiums in the second quarter of 2015 than in the second quarter of 2014 ($1213 million). The 2% increase for ongoing businesses includes crop at its underlying run rate.These increases were partially offset by the exit from the lawyers liability business ($7 million) and the termination of an affiliated reinsurance treaty ($5 million).
Reinsurance protection.  OneBeacon purchases reinsurance in order to minimize loss from large risks or catastrophic events. OneBeacon also purchases individual property reinsurance coverage for certain risks to reduce large loss volatility through property-per-risk excess of loss reinsurance programs and individual risk facultative reinsurance. OneBeacon also maintains excess of loss casualty reinsurance programs that provide protection for individual risk or catastrophe losses involving workers compensation, general liability, automobile liability, professional liability or umbrella liability. The availability and cost of reinsurance protection is subject to market conditions, which are outside of management’s control. Limiting risk of loss through reinsurance arrangements serves to mitigate the impact of large losses; however, the cost of this protection in an individual period may exceed the benefit.
OneBeacon's net combined ratio was higher than the gross combined ratio by 4 points for both the second quarter of 2015 and 2014. In both periods, the net combined ratio was higher than the gross combined ratio as a result of the cost of the reinsurance programs more than offsetting the benefits from ceded losses. 

OneBeacon Results—Six Months Ended June 30, 2015 versus Six Months Ended June 30, 2014
OneBeacon's GAAP combined ratio was 95% for the first six months of 2015 compared to 94% for the first six months of 2014. Net loss reserve development did not have a meaningful effect on the first six months of 2015 compared to 1 point of net unfavorable loss reserve development in the first six months of 2014. The first six months of 2015 also included 2 points of catastrophe losses, primarily related to wind and thunderstorms in the Midwest and Southern United States and winter storms in the Northeast United States in the first quarter, compared to 1 point of catastrophe losses in the second quarter of 2014.
OneBeacon’s net income for the six months ended June 30, 2015 was adversely impacted by a $4 million downward adjustment to the pre-tax gain on the sale of Essentia Insurance Company (Essentia). OneBeacon previously recognized a pre-tax gain of $23 million on its sale of Essentia, an indirect wholly-owned subsidiary which wrote legacy collector cars and boats business, to Markel Corporation during the first quarter of 2013. During the first quarter of 2015, OneBeacon recognized the loss of $4 million in other revenues in connection with an assessment from the Michigan Catastrophic Claims Association payable to Markel Corporation pursuant to the indemnification provisions in the stock purchase agreement governing the sale of Essentia. OneBeacon's net income for the first six months of 2015 was also adversely impacted by a $2 million write-off of capitalized software recorded as a loss in other revenues.
OneBeacon's net written premiums increased slightly to $608 million in the first six months of 2015. Increases from newer businesses, particularly OneBeacon Program Group and OneBeacon Surety Group, were substantially offset by the exit from the lawyers liability business and the termination of an affiliated reinsurance treaty.
OneBeacon’s net combined ratio was higher than the gross combined ratio by 65 points for the first quartersix months of 2015 and 4 points for the first quartersix months of 2014. In both periods, the net combined ratio was higher than the gross combined ratio as a result of the cost of the reinsurance programs more than offsetting the benefits from ceded losses.

Sirius Group Results—Three Months Ended March 31,June 30, 2015 versus Three Months Ended March 31,June 30, 2014
Sirius Group’sGroup's GAAP combined ratio was 81%78% for the firstsecond quarter of 2015 compared to 73%81% for firstsecond quarter of 2014. The increasedecrease in the combined ratio was primarily driven by lower favorable loss reserve development and change in business mix. Prior period loss development did not meaningfully impact the first quarter of 2015 compared to favorable loss reserve development of 5 points ($10 million) in the first quarter last year, primarily due to decreases in casualty and accident and health loss reserves. Additionally, the firstcatastrophe losses. The second quarter of 2015 included a decrease in property catastrophe excess business, which generally produces lower combined ratios in periods with light catastrophe activity. Both periods included 1 point2 points ($5 million) of catastrophe losses.
Inlosses, primarily from winter storms in the firstNortheast United States, compared to 6 points ($12 million) of catastrophe losses in the second quarter of 2014, primarily from storms and floods in Europe. Favorable loss reserve development was 5 points ($11 million) in the second quarter of 2015, primarily due to reductions for prior period catastrophe losses and run-off casualty business, compared to 3 points ($6 million) in the second quarter of 2014.
Sirius Group's gross written premiums decreased 6%increased 7% (a 10% increase in local currencies) to $423$256 million mainly due to foreign currency effects resulting from a strong U.S. dollar in 2015. In local currencies, gross premiums written were essentially flat compared to the first quarter last year, as decreases in property catastrophe excess were mostly offset by increasesan increase in accident and health.health premiums, partially offset by decreased property writings. Net written premiums decreased 9% (5%1% (flat in local currencies) to $303$184 million, driven by a decrease in property business andreflecting increased retrocessional purchases.purchases on property lines. Net earned premiums increased 3% for the second quarter of 2015 to $216 million due to higher accident and health premiums, partially offset by decreased property writings.

In the firstsecond quarter of 2015, Sirius Group’sGroup's other revenue was flat, as a $3 million mark-to-market loss on the swap executed in April of 2015, under which $100 million of the cash flows related to the SIG Senior Notes are swapped from U.S. dollars to Swedish kronor ($50 million) and euros ($50 million), was substantially offset by $2 million of gains on weather derivatives. In the second quarter of 2014, other revenue was a loss of $3 million, primarily due to the final settlement from the sale of a former affiliate in 2012, compared to a $1$2 million loss for the first quarter last year, which was primarily due to a loss on the interest rate cap associated with the SIG Preference Shares. Additionally, Sirius Group recorded $25$6 million of foreign currency translation gains in the second quarter of 2015 compared to $16 million of foreign currency translation losses in the first quarter of 2015 compared to $4 million of foreign currency translation gains in the firstsecond quarter of 2014 (See “Foreign Currency Translation” on page 55)67).
Sirius Group’sGroup's insurance and reinsurance acquisition expenses decreased $5$1 million in the firstsecond quarter of 2015, primarily due to lower net commissions on lower earned premiums for the property lines of business and lower net commission ratios on the accident and health line of business. Sirius Group’s other underwriting expenses decreased $6$2 million in the firstsecond quarter of 2015, primarily due to foreign exchange effects and decreased incentive compensation expenses.effects.
Reinsurance protection. Sirius Group’s reinsurance protection primarily consists of pro-rata and excess of loss protections to cover aviation, trade credit, and certain accident and health and property exposures. Sirius Group’s proportional reinsurance programs provide protection for part of the non-proportional treaty accounts written in Europe, the Americas, Asia, the Middle East and Australia. This reinsurance is designed to increase underwriting capacity where appropriate, and to reduce exposure both to large catastrophe losses and to a frequency of smaller loss events. Attachment points and coverage limits vary by region around the world.
Sirius Group's net combined ratio was 9 points higher than the gross combined ratio for the second quarter of 2015 and was 3 points lower than the gross combined ratio for the second quarter of 2014. For the second quarter of 2015, the net combined ratio was higher than the gross combined ratio due to property retrocessional coverage with limited loss recoveries. For the second quarter of 2014, the net combined ratio was lower than the gross combined ratio because ceded loss recoveries in the aviation and accident and health lines more than offset the cost of reinsurance protection.

Sirius Group Results—Six Months Ended June 30, 2015 versus Six Months Ended June 30, 2014
Sirius Group’s GAAP combined ratio was 79% for the first six months of 2015 compared to 77% for first six months of 2014. The increase in the combined ratio was driven by change in business mix and lower favorable loss reserve development, partially offset by lower catastrophe losses and lower other underwriting expenses. The first six months of 2015 included a decrease in property catastrophe excess business, which generally produces lower combined ratios in periods with light catastrophe activity. Favorable prior period loss development was 3 points ($11 million) the first six months of 2015 primarily due to decreases in casualty and accident and health loss reserves, compared to 4 points ($16 million) of favorable loss reserve development in the first six months of last year. The first six months of 2015 included 2 points ($7 million) of catastrophe losses primarily from winter storms in the Northeastern United States compared to 3 points ($14 million) in the first six months of last year.
In the first six months of 2015, gross written premiums decreased 2% to $680 million, mainly due to foreign currency effects resulting from a strong U.S. dollar in 2015. In local currencies, gross premiums written increased 3% compared to the first six months of 2014, as increases in accident and health were partially offset by decreases in property catastrophe excess writings. Net written premiums decreased 6% (3% in local currencies) to $488 million, driven by a decrease in property business and increased retrocessional purchases on property lines.
In the first six months of 2015, Sirius Group’s other revenue was a loss of $3 million, primarily due to a $3 million mark-to-market loss on the foreign currency swap executed in April 2015 and a $3 million loss on the final settlement from the sale of a former affiliate, partially offset by $3 million of gains on weather derivatives. In the first six months of 2014, other revenue was a loss of $4 million, primarily due to a $5 million loss on the interest rate cap associated with the SIG preference shares. Sirius Group recorded $19 million of foreign currency translation losses in the first six months of 2015 compared to $20 million of foreign currency translation losses in the first six months of 2014 (See “Foreign Currency Translation” on page 67).
Sirius Group’s insurance and reinsurance acquisition expenses decreased $6 million in the first six months of 2015, due to lower net commissions on lower earned premiums for the property lines of business and lower net commission ratios on the accident and health line of business. Sirius Group’s other underwriting expenses decreased $9 million in the first six months of 2015, primarily due to foreign exchange and decreased incentive compensation expenses..
Reinsurance protection. Sirius Group’s net combined ratio was 36 points higher than the gross combined ratio for the first quartersix months of 2015 and was 1 point higher than the gross combined ratio for the first quartersix months of 2014. For the first quartersix months of 2015, the higher net combined ratio was primarily due to an increase in property retrocessional protections with limited ceded loss recoveries. For the first quartersix months of 2014, the net combined ratio was higher than the gross combined ratio as a result of the cost of the reinsurance programs more than offsetting the benefits from ceded losses, and favorable loss reserve development on loss reserves that had no reinsurance cessions resulted in a lower gross combined ratio as compared to 2015.cessions.

White Mountains has established separate accounts with third party registered investment advisers to manage its publicly-traded common equity securities and convertibles. The largest of these separate account relationships arehave been with Prospector Partners LLC ("Prospector"), Lateef Investment Management ("Lateef"(“Lateef”) and Silchester International Investors ("Silchester"(“Silchester”).
White Mountains’s equity investment style has generally been value-oriented with a significant portion of the assets managed by Prospector.  As ofAt March 31, 2015, the Prospector separate account portfolios accounted for approximately 30% of White Mountains’s common equity securities, convertibles and other long-term investments. TheIn U.S. dollars, the Prospector separate account portfolios returned 0.8% in local currencies-0.7% and 1.0% in U.S0.3% during the second quarter and first six months of 2015. In U.S. dollars, the Prospector portfolios returned 3.2% and 6.7% for the second quarter and first six months of 2014.
During the second quarter of 2015, roughlyWhite Mountains instructed Prospector to liquidate its separate account portfolios and redeemed its investments in linethe Prospector Funds with the intention to reallocate a portion of its equity exposure to passive equity investment vehicles. During the second quarter of 2015, White Mountains purchased exchange traded funds (ETFs) that seek to provide investment results that, before expenses, generally correspond to the performance of the S&P 500, Russell 1000 and Russell 1000 Value Indices. As of June 30, 2015, White Mountains had invested $362 million in ETFs. The following summarizes White Mountains's investments in ETFs by exposure to each index:

IndexJune 30, 2015
S&P 500$300.4
Russell 1000 Value$43.0

In the second quarter of 2015, the ETFs earned the effective market return, of 1.0%.  In recent years,before expenses, over the Prospector separate account portfolios have lagged the S&P 500 Index return, howeverperiod in which White Mountains was invested in each respective fund. White Mountains has since inception in 2005 the Prospector separate account portfolios produced a 7.7% annualized return in U.S. dollars, roughly in line with the S&P 500 Index annualized return of 7.6%.  Theterminated its investment management agreements with Prospector will terminate during 2015.  As such, White Mountains intends to liquidate the Prospector separate account portfolios, and redeem Prospector-managed hedge funds during 2015 and invest the majority of the proceeds in passive equity vehicles.  At this time,Prospector.  White Mountains continues to have publicly-traded common equity securities actively managed by Lateef and Silchester.
The Lateef separate account is a highly concentrated portfolio of high quality mid- and large-cap growth companies. Lateef is a growth at a reasonable price manager focused on investing in high return on invested capital businesses at reasonable valuations. Lateef uses a bottom up, fundamental research-driven investment process that is focused on absolute returns, low turnover and a long-term investment horizon. As a highly concentrated portfolio of 15 to 20 positions, relative performance to the S&P 500 Index return is often driven, positively or negatively, by individual positions, especially in the short-term. The Lateef separate account returned 3.8%0.2% and 4.1% in both U.S. dollars and local currencies for the second quarter and first six months of 2015, slightly underperforming the S&P 500 Index return of 0.3% for the second quarter of 2015 but significantly outperforming the S&P 500 Index return of 1.0%.1.2% for the first six months of 2015. Lateef’s outperformance relative to the S&P 500 Index return in the quarterfirst six months of 2015 reflects positive contributions from merger and acquisition activity in the healthcare sector. The LateefLateef’s separate account returned 0.1%3.7% and 3.8% in both U.S. dollars and local currencies for the second quarter and first quartersix months of 2014, underperforming2014. Lateef’s relative underperformance to the S&P 500 Index return of 1.8%in both periods was primarily due to the broad stock market’s rotation away from growth stocks and into sectors such as utilities and energy where the portfolio had no exposure.

Foreign Currency Translation
White Mountains’s non-U.S. dollar-denominated assets and liabilities are valued using period-end exchange rates, and its non-U.S. dollar-denominated foreign revenues and expenses are valued using average exchange rates over the period.  Foreign currency exchange rate risk is the risk that White Mountains will incur losses on a U.S. dollar basis due to adverse changes in foreign currency exchange rates.  As of March 31,June 30, 2015, the following currencies represented the largest net foreign currency exposures as a percent of White Mountains’s common shareholders’ equity; the British pound sterling (4.7%(5.3%), the Swedish krona (2.4%kronor (2.5%), the euro (1.3%) and the Canadian dollar (1.2%).  White Mountains remains focused on defensively positioning its non-U.S. dollar denominated net foreign currency exposures, most of which reside at Sirius International. White Mountains’s net foreign currency exposure decreased $122$67 million and $189 million during the second quarter and first quartersix months of 2015, to $414 million at June 30, 2015 from $481 million at March 31, 2015 and from $603 million at December 31, 2014. This was primarily driven by a $153$100 million reductionforeign currency swap executed in the second quarter (see Foreign Currency Swap below) that reduced overall net foreign currency exposure to Swedish krona ($50 million) and euro ($50 million), offset by a $53 million increase in net Swedish krona exposure offset byand a $24$34 million increasereduction in net British pound sterling exposure and a $5 million increase in net euro exposure. The bulk of the decrease in the net Swedish krona exposure is due to sales and maturities of Swedish krona denominated investments during the quarter.other foreign currencies.
The following table illustrates the pre-tax effect that a hypothetical 10% increase (i.e. U.S. dollar strengthening) or decrease (i.e. U.S. dollar weakening) in the rate of exchange from the British pound sterling, the Swedish krona, the euroCanadian dollar and the Canadian dollareuro to the U.S. dollar would have on the carrying value of White Mountains’s net assets denominated in the respective currencies as of March 31,June 30, 2015 and December 31, 2014:

As of March 31,June 30, 2015, White Mountains’s investment portfolio included $0.8 billion in non-U.S. dollar-denominated investments, most of which arewere held at Sirius International and arewere denominated in British poundspound sterling, Swedish kronor, or euros. The value of the investments in this portfolio is impacted by changes in the exchange rate between the U.S. dollar and the pound sterling, the U.S. dollar and the krona, and the U.S. dollar and the euro. During the firstsecond quarter of 2015, the U.S. dollar strengthened 5.3%weakened 6% against the pound sterling, 11.4%5% against the krona, 2% against the Canadian dollar and 13.1%4% against the euro. During the first six months of 2015, the U.S. dollar weakened 1% against the pound sterling, strengthened 6% against the krona, strengthened 7% against the Canadian dollar and strengthened 8% against the euro. These currency movements resulted in approximately $72$40 million of pre-tax foreign currency investment gains and $32 million of pre-tax foreign currency losses for the second quarter and first quartersix months of 2015, which are recorded as components of net realized and unrealized investment gains (recognized in pre-tax income) and change in foreign currency translation on investments (recognized in other comprehensive income).  During the firstsecond quarter of 2014, the U.S. dollar weakened 0.5%3% against the pound sterling, strengthened 0.8%3% against the krona,kronor, weakened 3% against the Canadian dollar and strengthened 0.1%1% against the euro. During the first six months of 2014, the U.S. dollar weakened 2% against the pound sterling, strengthened 4% against the kronor, strengthened 1% against the Canadian dollar and strengthened 1% against the euro. These currency movements resulted in approximately $3$5 million and $7 million of pre-tax foreign currency investment losses.losses for the second quarter and first six months of 2014, which are recorded as components of net realized and unrealized investment gains (recognized in pre-tax income) and change in foreign currency translation on investments (recognized in other comprehensive income). 
Sirius International holds a large portfolio of investments that are denominated in U.S. dollars, but its functional currency is the Swedish krona. When Sirius International prepares its stand-alone GAAP financial statements, it translates its U.S. dollar-denominated investments to Swedish kronakronor and recognizes the related foreign currency translation gains or losses through pre-tax income. When White Mountains consolidates Sirius International, it translates Sirius International’s stand-alone GAAP financial statements to U.S. dollars and recognizes the foreign currency gains or losses arising from this translation, including those associated with Sirius International’s U.S. dollar-denominated investments, through other comprehensive income.  Since White Mountains reports its financial statements in U.S. dollars, there is no net effect to adjusted book value per share or to investment returns from foreign currency translation on its U.S. dollar-denominated investments at Sirius International.  However, net realized and unrealized investment gains, other revenues and other comprehensive income can be significantly affected during periods of high volatility in the foreign exchange rate between the U.S. dollar and other currencies, especially the Swedish krona.currencies.
The amount of foreign currency translation on Sirius International’s U.S. dollar-denominated investments recognized as a decreasean increase of other comprehensive income and an increasea decrease of net income was $61$25 million in the firstsecond quarter of 2015. The amount of foreign currency translation on Sirius International’s U.S. dollar-denominated investments recognized as a decrease of other comprehensive income and an increase of net income was $6$36 million infor the first six months of 2015. The amount of foreign currency translation on Sirius International’s U.S. dollar-denominated investments recognized as a decrease of other comprehensive income and an increase of net income was $22 million and $28 million for the second quarter and first six months of 2014.

LIQUIDITY AND CAPITAL RESOURCES
 
Operating Cash and Short-term Investments
Holding company level. The primary sources of cash for the Company and certain of its intermediate holding companies are expected to be distributions and tax sharing payments received from its insurance, reinsurance and other operating subsidiaries, capital raising activities, net investment income, proceeds from sales and maturities of investments and, from time to time, proceeds from the sales of operating subsidiaries. The primary uses of cash are expected to be repurchases of the Company’s common shares, payments on and repurchases/retirements of its debt obligations, dividend payments to holders of the Company’s common shares, to non-controlling interest holders of OneBeacon Ltd.’s common shares, and to holders of the SIG Preference Shares and to non-controlling interest holders of other consolidated subsidiaries, purchases of investments, payments to tax authorities, contributions to operating subsidiaries, operating expenses and, from time to time, purchases of operating subsidiaries.
Operating subsidiary level. The primary sources of cash for White Mountains’s insurance, reinsurance and other operating subsidiaries are expected to be premium and fee collections, net investment income, proceeds from sales and maturities of investments, contributions from holding companies, capital raising activities and, from time to time, proceeds from the sales of operating subsidiaries. The primary uses of cash are expected to be claim payments, policy acquisition costs, purchases of investments, payments on and repurchases/retirements of its debt obligations, distributions and tax sharing payments made to holding companies, distributions to non-controlling interest holders, operating expenses and, from time to time, purchases of operating subsidiaries.
Both internal and external forces influence White Mountains’s financial condition, results of operations and cash flows. Claim settlements, premium levels and investment returns may be impacted by changing rates of inflation and other economic conditions. In many cases, significant periods of time, sometimes several years or more, may lapse between the occurrence of an insured loss, the reporting of the loss to White Mountains and the settlement of the liability for that loss. The exact timing of the payment of claims and benefits cannot be predicted with certainty. White Mountains’s insurance and reinsurance operating subsidiaries maintain portfolios of invested assets with varying maturities and a substantial amount of cash and short-term investments to provide adequate liquidity for the payment of claims.
Management believes that White Mountains’s cash balances, cash flows from operations, routine sales and maturities of investments and the liquidity provided by the WTM Bank Facility are adequate to meet expected cash requirements for the foreseeable future on both a holding company and insurance, reinsurance and other operating subsidiary level.

Dividend Capacity
Under the insurance laws of the states and jurisdictions that White Mountains’s insurance and reinsurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing and the amount of dividends it may pay without prior approval by regulatory authorities. Accordingly, there can be no assurance regarding the amount of such dividends that may be paid by such subsidiaries in the future. Following is a description of the dividend capacity of White Mountains’s insurance and reinsurance operating subsidiaries:
 

57

OneBeacon:
OneBeacon’s top-tier regulated U.S. insurance operating subsidiary, Atlantic Specialty Insurance Company (“ASIC”), has the ability to pay dividends to its immediate parent during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus and subject to dividends paid in prior periods. Based upon the formula above, ASIC currently has the ability to pay $45 million of dividends without prior approval of regulatory authorities. As of DecemberMarch 31, 2014,2015, ASIC had $722$725 million of statutory surplus and $88$93 million of earned surplus. During the first quartersix months of 2015, ASIC did not pay anypaid $45 million of dividends to its immediate parent.
Split Rock has the ability to declare or pay dividends or make capital distributions during any 12-month period without the prior approval of Bermuda regulatory authorities on the condition that any such declaration or payment of dividends or capital distributions does not cause a breach of any of its regulatory solvency and liquidity requirements. During 2015, Split Rock has the ability to make capital distributions without the prior approval of regulatory authorities, subject to meeting all appropriate liquidity and solvency requirements, of $19 million, which is equal to 15% of its December 31, 2014 statutory capital (excluding earned surplus). During the first quartersix months of 2015, Split Rock did not pay any dividends to its immediate parent.

69

During the first quartersix months of 2015, OneBeacon’s unregulated insurance operating subsidiaries paid $5 million of dividends to their immediate parent. As of March 31,June 30, 2015, OneBeacon’s unregulated insurance operating subsidiaries had $52$110 million of net unrestricted cash, short-term investments, and fixed maturity investments and also had $101 million in par value of surplus notes, with a carrying value of $68$66 million, classified as other long-term investments.
During the first quartersix months of 2015, OneBeacon Ltd. paid a $20$40 million of regular quarterly dividenddividends to its common shareholders. White Mountains received $15$30 million of this dividend.these dividends.
As of March 31,June 30, 2015, OneBeacon Ltd. and its intermediate holding companies had $87$119 million of net unrestricted cash, short-term investments and fixed maturity investments and $90$82 million of common equity securities, convertibles and other long-term investments outside of its regulated and unregulated insurance operating subsidiaries.

Sirius Group:
Sirius Bermuda Insurance Ltd. ("(“Sirius Bermuda"Bermuda”), a class 3A licensed Bermuda insurer which owns Sirius International, has the ability to declare or pay dividends or make capital distributions during any 12-month period without the prior approval of Bermuda regulatory authorities on the condition that any such declaration or payment of dividends or capital distributions does not cause a breach of any of its regulatory solvency and liquidity requirements. During 2015, Sirius Bermuda has the ability, subject to meeting all appropriate liquidity and solvency requirements, to make dividend or capital distributions without the prior approval of regulatory authorities, subject to meeting all appropriate liquidity and solvency requirements, of $350 million, which is equal to 15% of its December 31, 2014 statutory capital, excluding earned surplus. The amount of dividends available to be paid by Sirius Bermuda in any given year is also subject to cash flow and earnings generated by Sirius Bermuda's business, as well as to dividends received from its subsidiaries, including Sirius International. During the first six months of 2015, Sirius Bermuda paid $85 million of dividends to its immediate parent.
Sirius International has the ability to pay dividends to Sirius Bermuda subject to the availability of unrestricted equity, calculated in accordance with the Swedish Act on Annual Accounts in Insurance Companies and the Swedish Supervisor Authorities (“Swedish FSA”). Unrestricted equity is calculated on a consolidated group account basis and on a parent account basis. Differences between the two include but are not limited to accounting for goodwill, subsidiaries (with parent accounts stated at original foreign exchange rates), taxes and pensions. Sirius International’s ability to pay dividends is limited to the “lower of” unrestricted equity as calculated within the group and parent accounts. As of December 31, 2014, Sirius International had $467 million (based on the December 31, 2014 SEK to USD exchange rate) of unrestricted equity on a parent account basis (the lower of the two) available to pay dividends in 2015. The amount of dividends available to be paid by Sirius International in any given year is also subject to cash flow and earnings generated by Sirius International’s business, as well as to dividends received from its subsidiaries, including Sirius America. Earnings generated by Sirius International’s business that are allocated to the Safety Reserve are not available to pay dividends (see “Safety Reserve” on the next page). During the first quartersix months of 2015, Sirius International did not pay anypaid $95 million of dividends to its immediate parent.

58

Subject to certain limitations under Swedish law, Sirius International is permitted to transfer certain portions of its pre-tax income to its Swedish parent companies to minimize taxes (referred to as a group contribution). On January 1, 2013, new tax legislation became effective in Sweden that limits the deductibility of interest paid on certain intra-group debt instruments. Uncertainty exists with respect to the interpretation of the legislation on existing intra-group debt instruments within the Sirius Group structure. During the first quartersix months of 2015, Sirius International did not transfer any of its 2014 pre-tax income to its Swedish parent companies.
Sirius America has the ability to pay dividends to Sirius International during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus and subject to dividends paid in prior periods. Based upon the formula above, Sirius America does not currently have the ability to pay dividends without prior approval of regulatory authorities.  As of DecemberMarch 31, 2014,2015, Sirius America had $621$627 million of statutory surplus and $82$94 million of earned surplus.  During the first quartersix months of 2015, Sirius America did not pay any dividends to its immediate parent.
As of March 31,June 30, 2015, Sirius Group and its intermediate holding companies had $30$70 million of net unrestricted cash, short-term investments and fixed maturity investments outside of its regulated and unregulated insurance and reinsurance operating subsidiaries. During the first quartersix months of 2015, Sirius Group did not pay any dividends to its immediate parent.

Capital Maintenance
There is a capital maintenance agreement between Sirius International and Sirius America, which obligates Sirius International to make contributions to Sirius America’s surplus in order for Sirius America to maintain surplus equal to at least 125% of the company action level risk based capital as defined in the NAIC Property/Casualty Risk-Based Capital Report. The agreement provides for a maximum contribution to Sirius America of $200 million.  Sirius International also provides Sirius America with accident year stop loss reinsurance, which protects Sirius America's accident year loss and allocated loss adjustment expense ratio in excess of 70%, with a limit of $90 million. This stop loss contract was in effect for all of 2014 and has been renewed for all of 2015 with the same terms.
 
Safety Reserve
Subject to certain limitations under Swedish law, Sirius International is permitted to transfer pre-tax income amounts into an untaxed reserve referred to as a safety reserve. At March 31,June 30, 2015, Sirius International's safety reserve amounted to SEK 10.4 billion, or $1.2$1.3 billion (based on the March 31,June 30, 2015 SEK to USD exchange rate). Under GAAP, an amount equal to the safety reserve, net of a related deferred tax liability established at the Swedish tax rate of 22.0%, is classified as shareholder’s equity. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain prescribed levels of premium writings and loss reserves in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities apply no taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations. Accordingly, under local statutory requirements, an amount equal to the deferred tax liability on Sirius International’s safety reserve ($266279 million at March 31,June 30, 2015) is included in solvency capital. Access to the safety reserve is restricted to coverage of insurance and reinsurance losses. Access for any other purpose requires the approval of Swedish regulatory authorities. Similar to the approach taken by Swedish regulatory authorities, most major rating agencies generally include the $1.2$1.3 billion balance of the safety reserve, without any provision for deferred taxes, in Sirius International’s regulatory capital when assessing Sirius International’s financial strength.

59

HG Global/BAM:
At March 31,June 30, 2015, HG Global had $613 million face value of preferred shares outstanding, of which White Mountains owned 96.9%. Holders of the HG Global preferred shares receive cumulative dividends at a fixed annual rate of 6.0% on a quarterly basis, when and if declared by HG Global. HG Global did not declare or pay any preferred dividends in the first quartersix months of 2015. As of March 31,June 30, 2015, HG Global has accrued $107$118 million of dividends payable to holders of its preferred shares, $104$114 million of which is payable to White Mountains and eliminated in consolidation.
HG Re is a Special Purpose Insurer subject to regulation and supervision by the BMA, but does not require regulatory approval to pay dividends. However, HG Re’s dividend capacity is limited by amounts held in the collateral trusts pursuant to the first loss reinsurance treaty (“FLRT”) with BAM. As of December 31, 2014, HG Re had statutory capital of $445 million, of which $44 million primarily relates to accrued interest on the BAM Surplus Notes held by HG Re, and $403 million was held as collateral in the Supplemental Trust pursuant to the FLRT with BAM.
Effective January 1, 2014, HG Global and BAM agreed to change the interest rate on the BAM surplus notes for the five years ending December 31, 2018 from a fixed rate of 8% to a variable rate equal to the one-year U.S. treasury rate plus 300 basis points, set annually, which is 3.15% for 2015. Prior to the end of 2018, BAM has the option to extend the variable rate period for an additional three years.  At the end of the variable rate period, the interest rate will be fixed at the higher of the then current variable rate or 8%.  BAM is required to seek regulatory approval to pay interest and principal on its surplus notes only when adequate capital resources have accumulated beyond BAM’s initial capitalization and a level that continues to support its outstanding obligations, business plan and ratings.

Other Operations:
During the first quartersix months of 2015, WM Advisors did not pay any dividends to its immediate parent. At March 31,June 30, 2015, WM Advisors had $12$14 million of net unrestricted cash, short-term investments and fixed maturity investments.
During the first quartersix months of 2015, White Mountains paid a $6 million common share dividend. At March 31,June 30, 2015, the Company and its intermediate holding companies had $247$264 million of net unrestricted cash, short-term investments and fixed maturity investments, $173$195 million of common equity securities and $114$61 million of other long-term investments included in its Other Operations segment.

WM Life Re Keep-Well Agreement
Sirius Group initially fronted the reinsurance contracts covering guaranteed living and death benefits of Japanese variable annuity contracts for, and was 100% reinsured by, WM Life Re. In October 2013, White Mountains and Tokio Marine completed a novation whereby Sirius Group’s obligations on the reinsurance contracts were transferred to WM Life Re. As a result, Sirius Group no longer has any obligation or liability relating to these agreements. In connection with this novation agreement, White Mountains and Life Re Bermuda entered into a keep-well agreement, which obligates White Mountains to make capital contributions to Life Re Bermuda in the event that Life Re Bermuda’s shareholder’s equity falls below $75 million, provided however that in no event shall the amount of all capital contributions made by White Mountains under this agreement exceed $127 million. During the first quartersix months of 2015, White Mountains contributed $8 million to Life Re Bermuda. At March 31,June 30, 2015, Life Re Bermuda had $79 million of shareholder’s equity and White Mountains’s maximum capital commitment under the keep-well agreement was $111 million. WM Life Re is in runoff and all of its contracts will mature by June 30, 2016.

 Insurance Float

Insurance float is an important aspect of White Mountains’s insurance operations. Insurance float represents funds that an insurance or reinsurance company holds for a limited time. In an insurance or reinsurance operation, float arises because premiums are collected before losses are paid. This interval can extend over many years. During that time, the insurer or reinsurer invests the funds. When the premiums that an insurer or reinsurer collects do not cover the losses and expenses it eventually must pay, the result is an underwriting loss, which can be considered as the cost of insurance float.  One manner in which White Mountains calculates its insurance float is by taking its insurance liabilities and subtracting its insurance assets. Prior to December 31, 2014, White Mountains had calculated its insurance float by taking its net investment assets and subtracting its total adjusted capital. With the acquisitions of Tranzact, MediaAlpha and Wobi in 2014, the previous presentation had become less meaningful. The current presentation simplifies the insurance float calculation by including only insurance assets and liabilities, which is also more consistent with traditional insurance float presentations. Although insurance float can be calculated using numbers determined under GAAP, insurance float is not a GAAP concept and, therefore, there is no comparable GAAP measure.

72

Insurance float can increase in a number of ways, including through acquisitions of insurance and reinsurance operations, organic growth in existing insurance and reinsurance operations and recognition of losses that do not immediately cause a corresponding reduction in investment assets.  Conversely, insurance float can decrease in a number of other ways, including sales of insurance and reinsurance operations, shrinking or runoff of existing insurance and reinsurance operations, the acquisition of operations that do not have substantial investment assets (e.g., an agency) and the recognition of gains that do not cause a corresponding increase in investment assets.  It is White Mountains’s intention to generate low-cost float over time through a combination of acquisitions and organic growth in its existing insurance and reinsurance operations. However, White Mountains seeks to increase overall profitability sometimes by reducing insurance float, such as in the Runoff Transaction.

61

Certain operational leverage metrics can be measured with ratios that are calculated using insurance float.  There are many activities that do not change the amount of insurance float at an insurance or reinsurance company but can have a significant impact on the company’s operational leverage metrics.  For example, investment gains and losses, foreign currency gains and losses, debt issuances and repurchases/retirements, common and preferred share issuances and repurchases and dividends paid to shareholders are all activities that do not change insurance float but that can meaningfully impact operational leverage metrics that are calculated using insurance float.

(1) While classified as a liability for GAAP purposes, as a result of the indefinite deferral of these taxes, Swedish regulatory authorities apply no taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations. Accordingly, under local statutory requirements, an amount equal to the deferred tax liability on Sirius International’s safety reserve is included in solvency capital (see “Safety Reserve” on page 59)71).

During the first threesix months of 2015, insurance float decreased by $149$199 million, primarily due to reduced loss and LAE reserve balances resulting from payments on prior losses exceeding the growth in loss reserves from new business at both OneBeacon and Sirius Group. In July 2015, White Mountains reached a definitive agreement to sell the Sirius Group to CMI. If this transaction had closed as of June 30, 2015, White Mountains's insurance float would have decreased by approximately $1.4 billion. Insurance float would have decreased by approximately $1.6 billion had the transaction taken place as of December 31, 2014. (See Note 19 - “Subsequent Events”).

Management believes that White Mountains has the flexibility and capacity to obtain funds externally as needed through debt or equity financing on both a short-term and long-term basis. However, White Mountains can provide no assurance that, if needed, it would be able to obtain additional debt or equity financing on satisfactory terms, if at all.
White Mountains has an unsecured revolving credit facility with a syndicate of lenders administered by Wells Fargo Bank, N.A., which has a total commitment of $425 million and a maturity date of August 14, 2018 (the “WTM Bank Facility”). During the second quarter of 2015, White Mountains borrowed and subsequently repaid $15 million under the WTM Credit Facility. As of March 31,June 30, 2015, the WTM Bank Facility was undrawn.
The WTM Bank Facility contains various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including certain minimum net worth and maximum debt to capitalization standards.
It is possible that, in the future, one or more of the rating agencies may lower White Mountains’s existing ratings. If one or more of its ratings were lowered, White Mountains could incur higher borrowing costs on future borrowings and its ability to access the capital markets could be impacted.
Tranzact has a secured credit facility with a syndicate of lenders administered by The PrivateBank and Trust Company (the “Tranzact Bank Facility”). The Tranzact Bank Facility consists of a $70 million term loan facility, which had an outstanding balance of $67 million as of March 31,June 30, 2015, and a revolving credit facility for an additional $4.5$12 million, of which $5 million was fully drawn as of March 31,June 30, 2015. During the first quartersix months of 2015, Tranzact repaid $1$3 million under the term loan portion and borrowed $4.5$5 million under the revolving portion of the Tranzact Bank Facility. The Tranzact Bank Facility is secured by intellectual property and the common stock of Tranzact and its subsidiaries and contains various affirmative, negative and financial covenants which White Mountains considers to be customary for such borrowings, including a minimum fixed charge coverage ratio and a maximum leverage ratio.  The Tranzact Bank Facility carries a variable interest rate, based on the U.S. dollar LIBOR rate. Tranzact has entered into an interest rate swap agreement to effectively fix the rate it pays on the $70 million term loan portion of the facility (seefacility. (See Note 9 — Derivatives- “Derivatives” for details)).
In November 2012, OBH issued $275 million face value of senior unsecured debt through a public offering, at an issue price of 99.9% (the “OBH Senior Notes”). The net proceeds from the issuance of the OBH Senior Notes were used to repurchase OBH’s previously issued Senior Notes. The OBH Senior Notes, which are fully and unconditionally guaranteed as to the payment of principal and interest by OneBeacon Ltd., bear an annual interest rate of 4.60%, payable semi-annually in arrears on May 9 and November 9, until maturity on November 9, 2022.

74

In March 2007, SIG issued $400 million face value of senior unsecured notes at an issue price of 99.715% (the “SIG Senior Notes”). The SIG Senior Notes bear an annual interest rate of 6.375%, payable semi-annually in arrears on March 20 and September 20, until maturity in March 2017.

63

The 2012 OBH Senior Notes and the SIG Senior Notes were issued under indentures that contain restrictive covenants which, among other things, limit the ability of OneBeacon Ltd., OBH, SIG and their respective subsidiaries to create liens and enter into sale and leaseback transactions and limits the ability of OneBeacon Ltd., OBH, SIG and their respective subsidiaries to consolidate, merge or transfer their properties and assets. The indentures do not contain any financial ratios or specified levels of net worth or liquidity to which OneBeacon Ltd., OBH or SIG must adhere.

Stand By Letter of Credit Facilities
On November 25, 2014, Sirius International entered into two stand by letter of credit facility agreements totaling $200 million to provide capital support for its Lloyds Syndicate 1945. One letter of credit is a $125 million facility from Nordea Bank Finland plc (“the Nordea facility”), $100 million of which is issued on an unsecured basis. The second letter of credit is a $75 million facility with Lloyds Bank plc (“the Lloyds Bank facility”), $25 million of which is issued on an unsecured basis. The Nordea facility and the Lloyds Bank facility are renewable annually. The unsecured portions of the Nordea and Lloyds Bank facilities are subject to various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including certain minimum net worth and maximum debt to capitalization standards.
Sirius International has other secured letter of credit and trust arrangements with various financial institutions to support its insurance operations.

Covenant Compliance

FAIR VALUE CONSIDERATIONS
 
General
White Mountains records certain assets and liabilities at fair value in its consolidated financial statements, with changes therein recognized in current period earnings. In addition, White Mountains discloses estimated fair value for certain liabilities measured at historical or amortized cost. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price) at a particular measurement date. Fair value measurements are categorized into a hierarchy that distinguishes between inputs based on market data from independent sources (“observable inputs”) and a reporting entity’s internal assumptions based upon the best information available when external market data is limited or unavailable (“unobservable inputs”). Quoted prices in active markets for identical assets have the highest priority (“Level 1”), followed by observable inputs other than quoted prices including prices for similar but not identical assets or liabilities (“Level 2”), and unobservable inputs, including the reporting entity’s estimates of the assumptions that market participants would use, having the lowest priority (“Level 3”).
Assets and liabilities carried at fair value include substantially all of the investment portfolio; derivative instruments, both exchange traded and over the counter instruments; and reinsurance assumed liabilities associated with variable annuity benefit guarantees. Valuation of assets and liabilities measured at fair value require management to make estimates and apply judgment to matters that may carry a significant degree of uncertainty. In determining its estimates of fair value, White Mountains uses a variety of valuation approaches and inputs. Whenever possible, White Mountains estimates fair value using valuation methods that maximize the use of observable prices and other inputs. Where appropriate, assets and liabilities measured at fair value have been adjusted for the effect of counterparty credit risk.


77

Invested Assets
White Mountains’s invested assets that are measured at fair value include fixed maturity securities, common and preferred equity securities, convertible fixed maturity and preferred investments and interests in hedge funds and private equity funds.
Where available, the estimated fair value of investments is based upon quoted prices in active markets. In circumstances where quoted prices are unavailable, White Mountains uses fair value estimates based upon other observable inputs including matrix pricing, benchmark interest rates, market comparables, and other relevant inputs. Where observable inputs are not available, the estimated fair value is based upon internal pricing models using assumptions that include inputs that may not be observable in the marketplace but which reflect management’s best judgment given the circumstances and consistent with what other market participants would use when pricing such instruments.
As of March 31,June 30, 2015, approximately 92%93% of the investment portfolio recorded at fair value was priced based upon quoted market prices or other observable inputs. Investments valued using Level 1 inputs include fixed maturity securities, primarily investments in U.S. Treasuries, common equity securities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs comprise fixed maturity securities including corporate debt, state and other governmental debt, convertible fixed maturity securities and mortgage and asset-backed securities. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Level 3 fair value estimates based upon unobservable inputs include White Mountains’s investments in hedge funds and private equity funds, as well as investments in certain debt securities, including asset-backed securities, where quoted market prices are unavailable. White Mountains determines when transfers between levels have occurred as of the beginning of the period. White Mountains uses brokers and outside pricing services to assist in determining fair values. For investments in active markets, White Mountains uses the quoted market prices provided by outside pricing services to determine fair value. The outside pricing services used by White Mountains have indicated that if no observable inputs are available for a security, they will not provide a price.

66

In those circumstances, White Mountains estimates the fair value using industry standard pricing models and observable inputs such as benchmark interest rates, market comparables, broker quotes, issuer spreads, bids, offers, credit rating prepayment speeds and other relevant inputs. White Mountains performs procedures to validate the market prices obtained from the outside pricing sources. Such procedures, which cover substantially all of its fixed maturity investments include, but are not limited to, evaluation of model pricing methodologies and review of the pricing services’ quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from different independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices, and review of assumptions utilized by the pricing service for selected measurements on an ad hoc basis throughout the year. White Mountains also performs back-testing of selected sales activity to determine whether there are any significant differences between the market price used to value the security prior to sale and the actual sale price on an ad-hoc basis throughout the year. Prices provided by the pricing services that vary by more than 5% and $1 million from the expected price based on these procedures are considered outliers. Also considered outliers are prices that have not changed from period to period and prices that have trended unusually compared to market conditions. In circumstances where the results of White Mountains’s review process do not appear to support the market price provided by the pricing services, White Mountains challenges the price.  The fair values of such securities are considered to be Level 3 measurements.

Variable Annuity Reinsurance Liabilities
White Mountains has entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan. White Mountains carries the benefit guarantees at fair value. The fair value of the guarantees is estimated using actuarial and capital market assumptions related to the projected discounted cash flows over the term of the reinsurance agreement. The valuation uses assumptions about surrenders rates, market volatilities and other factors, and includes a risk margin which represents the additional compensation a market participant would require to assume the risks related to the business. The selection of surrender rates, market volatility assumptions, risk margins and other factors require the use of significant management judgment. Assumptions regarding future policyholder behavior, including surrender and lapse rates, are generally unobservable inputs and significantly impact the fair value estimate. Market conditions including, but not limited to, changes in interest rates, equity indices, market volatility and foreign currency exchange rates as well as variations in actuarial assumptions regarding policyholder behavior may result in significant fluctuations in the fair value of the liabilities associated with these guarantees that could materially affect results of operations. All of White Mountains’s variable annuity reinsurance liabilities $(1)$(1.8) million were classified as Level 3 measurements at March 31,June 30, 2015. 

78

WM Life Re projects future surrender rates by year for policies based on a combination of actual experience and expected policyholder behavior.  Actual policyholder behavior, either individually or collectively, may differ from projected behavior as a result of a number of factors such as the level of the account value versus guarantee value and applicable surrender charge, views of the primary insurance company’s financial strength and ability to pay the guarantee at maturity, annuitants’ need for money in a prolonged recession and time remaining to receive the guarantee at maturity.  Policyholder behavior is especially difficult to predict given that WM Life Re's reinsurance contracts are relatively new and the market turmoil seen over the last several years is unprecedented for this type of product in the Japanese market.  Actual policyholder behavior may differ materially from WM Life Re’s projections.
At the account value levels as of March 31,June 30, 2015, the average assumed surrender rate was approximately 40% per annum. The potential change in the fair value of the liability due to a change in current surrender assumptions is as follows: 
 Change in fair value of liability Change in fair value of liability
Millions March 31, 2015 December 31, 2014 June 30, 2015 December 31, 2014
Decrease 100% (to zero surrenders) $(0.4) $(0.2) $(0.4) $(0.2)
Increase 100% $0.2
 $(0.1) $0.2
 $(0.1)
 
The amounts in the table above could increase in the future if the fair value of the variable annuity guarantee liability changes due to factors other than the surrender assumptions (e.g., a decline in the ratio of the annuitants’ aggregate account values to their aggregate guarantee values). 


67

NON-GAAP FINANCIAL MEASURES
 
This report includes three 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’s results of operations and financial condition.
Adjusted comprehensive income is a non-GAAP financial measure that excludes the change in equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes, from comprehensive income. In the calculation of comprehensive income under GAAP, fixed maturity investments are marked-to-market while the liabilities to which those assets are matched are not. Symetra attempts to earn a “spread” between what it earns on its investments and what it pays out on its products. In order to try to fix this spread, Symetra invests in a manner that tries to match the duration and cash flows of its investments with the required cash outflows associated with its life insurance and structured settlements products. As a result, Symetra typically earns the same spread on in-force business whether interest rates fall or rise. Further, at any given time, some of Symetra’s structured settlement obligations may extend 40 or 50 years into the future, which is further out than the longest maturing fixed maturity investments regularly available for purchase in the market (typically 30 years). For these long-dated products, Symetra is unable to fully match the obligation with assets until the remaining expected payout schedule comes within the duration of securities available in the market. If at that time, these fixed maturity investments have yields that are lower than the yields expected when the structured settlement product was originally priced, the spread for the product will shrink and Symetra will ultimately harvest lower returns for its shareholders. GAAP comprehensive income increases when rates decline, which would suggest an increase in the value of Symetra - the opposite of what is happening to the intrinsic value of the business. Therefore, White Mountains’s management and Board of Directors use adjusted comprehensive income when assessing Symetra’s quarterly financial performance. In addition, this measure is typically the predominant component of change in adjusted book value per share, which is used in calculation of White Mountains’s performance for both short-term (annual bonus) and long-term incentive plans. The reconciliation of adjusted comprehensive income to comprehensive income is included on page 45.53.
Adjusted book value per share is a non-GAAP measure which is derived by expanding the GAAP calculation of book value per White Mountains common share to exclude equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes. In addition, the number of common shares outstanding used in the calculation of adjusted book value per share is 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 44.52.
Total capital at White Mountains is comprised of White Mountains’s common shareholders’ equity, debt and non-controlling interest in OneBeacon Ltd., HG Global and the SIG Preference Shares. Total adjusted capital excludes the equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes from total capital. The reconciliation of total capital to total adjusted capital is included on page 63.74.

All statements, other than statements of historical facts, included or referenced in this report which address activities, events or developments which White Mountains expects or anticipates will or may occur in the future are forward-looking statements. The words “will”, “believe”, “intend”, “expect”, “anticipate”, “project”, “estimate”, “predict” and similar expressions are also intended to identify forward-looking statements. These forward-looking statements include, among others, statements with respect to White Mountains’s:

projections of revenues, income (or loss), earnings (or loss) per share, dividends, market share or other financial forecasts;
expansion and growth of its business and operations; and
future capital expenditures.
 
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. However, whether actual results and developments will conform with its expectations and predictions is subject to a number of risks and uncertainties that could cause actual results to differ materially from expectations, including:
 
the risks associated with Item 1A of White Mountains’s 2014 Annual Report on Form 10-K;
claims arising from catastrophic events, such as hurricanes, earthquakes, floods, fires, terrorist attacks or severe winter weather;
the continued availability of capital and financing;
general economic, market or business conditions;
business opportunities (or lack thereof) that may be presented to it and pursued;
competitive forces, including the conduct of other property and casualty 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; and
other factors, most of which are beyond White Mountains’s control.
 
Consequently, all of the forward-looking statements made in this report 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. White Mountains assumes no obligation to publicly update any such forward-looking statements, whether as a result of new information, future events or otherwise.
