NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The Company is an exempted Bermuda limited liability company whose principal businesses are conducted through its insurance subsidiaries and other affiliates. The Company’s headquarters is located at 26 Reid Street, Hamilton, Bermuda HM 11, its principal executive office is located at 80 South Main Street, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11.

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of White Mountains Insurance Group, Ltd. (the “Company” or the “Registrant”), its subsidiaries (collectively with the Company, “White Mountains”) and other entities required to be consolidated under GAAP.

Consolidation Principles

Under GAAP, the Company is required to consolidate any entity in which it holds a controlling financial interest. A controlling financial interest is usually in the form of an investment representing the majority of the subsidiary’s voting interests. However, a controlling financial interest may also arise from a financial interest in a variable interest entity (“VIE”) through arrangements that do not involve ownership of voting interests. The Company consolidates a VIE if it determines that it is the primary beneficiary. The primary beneficiary is defined as the entity who holds a variable interest that gives it both the power to direct the VIE’s activities that most significantly impact its economic performance and the obligation to absorb losses of, or the right to receive returns from, the VIE that could potentially be significant to the VIE.

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 state 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 2017 Annual Report on Form 10-K.

Use of Estimates

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.

Reportable Segments

White Mountains has determined its reportable segments based on the nature of the underlying businesses, the manner in which the Company’s subsidiaries and affiliates are organized and managed and the organization of the financial information provided to the chief operating decision maker to assess performance and make decisions regarding allocation of resources. White Mountains’s reportable segments are HG Global/BAM, MediaAlpha and Other Operations. See Note 12 — “Segment Information”.

The HG Global/BAM segment consists of HG Global Ltd. and its wholly-owned subsidiaries (“HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”) (collectively, “HG Global/BAM”). BAM is the first and only mutual municipal bond insurance company in the United States. By insuring the timely payment of principal and interest, BAM provides market access to, and lowers interest expense for, issuers of municipal bonds used to finance essential public purposes such as schools, utilities and transportation facilities. BAM is owned by and operated for the benefit of its members, the municipalities that purchase BAM’s insurance for their debt issuances. HG Global was established to fund the startup of BAM and, through its wholly-owned subsidiary, HG Re Ltd. (“HG Re”), to provide up to 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. 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”). As of March 31, 2018, $499.0 million of the surplus notes remain outstanding. As of March 31, 2018 and December 31, 2017, White Mountains owned 96.9% of HG Global’s preferred equity and 88.4% of its common equity. White Mountains does not have an ownership interest in BAM. However, White Mountains is required to consolidate BAM’s results in its financial statements because BAM is a VIE for which White Mountains is the primary beneficiary. BAM’s results are attributed to non-controlling interests.

The MediaAlpha segment consists of QL Holdings LLC and its wholly-owned subsidiary QuoteLab, LLC (collectively “MediaAlpha”). MediaAlpha is a leading marketing technology company that develops technology that enables the programmatic buying and selling of vertical-specific, performance-based media between advertisers (buyers of advertising inventory) and publishers (sellers of advertising inventory) through cost-per-click, cost-per-call and cost-per-lead pricing models. MediaAlpha's media buying platform enables advertisers to create and automate data-driven bidding strategies designed to improve the efficiency and enhance overall performance of their marketing campaigns that target high-intent consumers at the time and place they are ready to purchase. MediaAlpha’s publisher platform is used by publishers to sell their vertical-specific, performance-based media to advertisers through transparent, programmatic, auction-based marketplaces. MediaAlpha works with 550 advertisers and 325 publishers across a number of insurance (auto, motorcycle, home, renter, health and life) and non-insurance (travel, education, personal finance and home services) verticals.

White Mountains’s Other Operations segment consists of the Company, its wholly-owned subsidiary, White Mountains Capital, Inc. (“WM Capital”), its wholly-owned investment management subsidiary, White Mountains Advisors LLC (“WM Advisors”), and its other intermediate holding companies, as well as certain consolidated and unconsolidated private capital and other investments. The consolidated private capital investments include Wobi Insurance Agency Ltd. (“Wobi”) and Removal Stars Ltd. (“Buzzmove”). During 2017, White Mountains revised certain of its previously issued financial statements for amounts relating to Wobi. See Note 17 — “Financial Statement Revisions”.

Discontinued Operations and Assets and Liabilities Held for Sale

On September 28, 2017, Intact Financial Corporation completed its acquisition of OneBeacon Insurance Group, Ltd. (“OneBeacon”) in an all-cash transaction for $18.10 per share (the “OneBeacon Transaction”). On July 21, 2016, White Mountains completed its sale of Tranzact Holdings, LLC (“Tranzact”) to an affiliate of Clayton, Dubilier & Rice, LLC. On April 18, 2016, White Mountains completed its sale of Sirius International Insurance Group, Ltd. (“Sirius Group”) to CM International Pte. Ltd. and CM Bermuda Limited (collectively “CMI”), the Singapore-based investment arm of China Minsheng Investment Corp., Ltd. White Mountains has presented the results of OneBeacon, Tranzact and Sirius Group as discontinued operations in the statement of operations and comprehensive income and their assets and liabilities as held for sale in the balance sheet for all periods prior to the completion of each transaction.

White Mountains has classified its Guilford, Connecticut property, which consists of an office building and adjacent land, as held for sale as of March 31, 2018 and December 31, 2017. See Note 16 — “Held for Sale and Discontinued Operations”.

Significant Accounting Policies

Refer to the Company’s 2017 Annual Report on Form 10-K for a complete discussion regarding White Mountains’s significant accounting policies.

Recently Adopted Changes in Accounting Principles

Revenue Recognition

On January 1, 2018, White Mountains adopted ASU 2014-09, Revenue from Contracts with Customers (ASC 606), which modifies the guidance for revenue recognition. Under ASU 2014-09, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled once it fulfills its performance obligations under the terms of its contract with the customer. The scope of the new guidance includes agent commissions and other non-insurance revenues. Adoption of ASU 2014-09 did not have any impact on White Mountains's financial statements.

Share-Based Compensation

On January 1, 2018, White Mountains adopted ASU 2017-09, Stock Compensation: Scope of Modification Accounting (ASC 718), which narrows the scope of transactions subject to modification accounting to changes in terms of an award that result in a change in the award’s fair value, vesting conditions or classification. Adoption of ASU 2017-09 did not have any impact on White Mountains’s financial statements.

On January 1, 2017, White Mountains adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (ASC 718) which simplifies certain aspects of the accounting for share-based compensation. The new guidance provides an accounting policy election to account for forfeitures by either applying an assumption, as required under existing guidance, or by recognizing forfeitures when they actually occur. At adoption, White Mountains did not change its accounting policy for forfeitures, which is to apply an assumed forfeiture rate. The new guidance has also changed the threshold for partial cash settlement to settle statutory withholding requirements for equity classified awards, increasing the threshold up to the maximum statutory tax rate. As a result of adoption, White Mountains reported $8.4 million and $6.5 million of statutory withholding tax payments made in connection with the settlement of restricted shares as financing cash flows for the three-month periods ended March 31, 2018 and 2017. Such payments were classified as operating cash flows prior to adoption.

In addition, the new guidance changed the treatment for excess tax benefits which arise from the difference between the deduction for tax purposes and the compensation costs recognized for financial reporting. Under the new guidance, a reporting entity recognizes excess tax benefits or expense in current period earnings, regardless of whether it is in a taxes payable position.

Business Combinations

On January 1, 2018, White Mountains adopted ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (ASC 805), which clarifies the definition of a business and affects the determination of whether acquisitions or disposals are accounted for as assets or as a business. Under the new guidance, when substantially all of the fair value of the assets is concentrated in a single identifiable asset or group of similar assets, it is not a business. White Mountains has not had any transactions falling within the scope of ASU 2017-01 during the period ended March 31, 2018 and, accordingly, adoption did not have any impact on White Mountains's financial statements.

Cash Flow Statement

On January 1, 2018, White Mountains adopted ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (ASC 230), which addresses the classification and presentation of certain items, including debt prepayment and extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees, for which there was diversity in practice prior to the issuance of ASU 2016-15. Also on January 1, 2018, White Mountains adopted ASU 2016-18, Statement of Cash Flows: Restricted Cash (ASC 230), which modifies the guidance for the treatment of restricted cash amounts in the cash flow statement. The new guidance requires restricted cash to be included in the reconciliation of beginning and end-of-period amounts presented on the statement of cash flows and requires a description of the nature of the changes in restricted cash during the periods presented. Adoption of ASU 2016-15 and ASU 2016-18 did not have any impact on White Mountains's statement of cash flows.

Financial Instruments - Recognition and Measurement

On January 1, 2018, White Mountains adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (ASC 825-10), which modifies the guidance for financial instruments, including investments in equity securities. Under the new guidance, all equity securities with readily determinable fair values are required to be measured at fair value with changes therein recognized through current period earnings. In addition, the new ASU requires a qualitative assessment for equity securities without readily determinable fair values to identify impairment, and for impaired equity securities to be measured at fair value. White Mountains measures its portfolio of investment securities at fair value with changes therein recognized through current period earnings and, accordingly, adoption of ASU 2016-01 did not have any impact on White Mountains's financial statements.

Recently Issued Accounting Pronouncements

Premium Amortization on Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities (ASC 310-20), which changes the amortization period for certain purchased callable debt securities. Under the new guidance, for investments in callable debt securities held at a premium, the premium will be amortized over the period to the earliest call date. The new guidance does not change the amortization period for callable debt securities held at a discount. ASU 2017-08 is not expected to have any impact on White Mountains's financial statements at adoption but may affect the amortization recognized in future periods.

Credit Losses

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (ASC 326), which establishes new guidance for the recognition of credit losses for financial assets measured at amortized cost. The new ASU requires reporting entities to estimate the credit losses expected over the life of a credit exposure using historical information, current information and reasonable and supportable forecasts that affect the collectability of the financial asset. This differs from current GAAP, which delays recognition until it is probable a loss has been incurred. The new guidance is expected to accelerate recognition of credit losses. The types of assets within the scope of the new guidance include premium receivables, reinsurance recoverables and loans. ASU 2016-13 is effective for annual periods beginning after January 1, 2020, including interim periods. White Mountains measures its portfolio of investment securities at fair value with changes therein recognized through current period earnings and, accordingly, does not expect adoption to have any effect on its financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The new guidance requires lessees to recognize lease assets and liabilities on the balance sheet for both operating and financing leases, with the exception of leases with an original term of 12 months or less. Under existing guidance recognition of lease assets and liabilities is not required for operating leases. The lease assets and liabilities to be recognized are both measured initially based on the present value of the lease payments. Under the new guidance, a sale-leaseback transaction must meet the recognition criteria under ASC 606, Revenues, in order to be accounted for as sale. The new guidance is effective for White Mountains for years beginning after December 15, 2018, including interim periods therein. White Mountains is evaluating the expected impact of this guidance and available adoption methods.

Note 2. Significant Transactions

Dispositions

OneBeacon

On September 28, 2017, White Mountains received $1.3 billion in cash proceeds from the OneBeacon Transaction and recorded a gain of $554.6 million, net of transaction costs. As a result of the OneBeacon Transaction, OneBeacon’s results have been reported as discontinued operations within White Mountains’s GAAP financial statements. See Note 16 — “Held for Sale and Discontinued Operations”.

Star & Shield

On March 7, 2017, White Mountains completed the sale of Star & Shield Services LLC, Star & Shield Risk Management LLC, and Star & Shield Claims Services LLC (collectively “Star & Shield”) and its investment in Star & Shield Insurance Exchange (“SSIE”) surplus notes to K2 Insurance Services, LLC. White Mountains did not recognize any gain or loss on the sale. Through December 31, 2016, Star & Shield’s assets and liabilities are reported as held for sale within White Mountains’s GAAP financial statements. See Note 16 — “Held for Sale and Discontinued Operations”.

Acquisitions

The following acquisitions are included in White Mountains’s consolidated financial statements from the date of acquisition. The assets acquired and liabilities assumed have been measured at their acquisition date fair values.

DavidShield

On January 24, 2018, White Mountains acquired 50% of DavidShield Life Insurance Agency (2000) Ltd. (“DavidShield”), its joint venture partner in PassportCard Limited (“PassportCard”). DavidShield is a managing general agency that is the leading provider of expatriate medical insurance in Israel and uses the same card-based delivery system as PassportCard. As part of the transaction, White Mountains restructured its equity stake in PassportCard so that White Mountains and its partner in DavidShield would each own 50% of both businesses. To facilitate the transaction, White Mountains provided financing to its partner in the form of a non-interest bearing loan that is secured by the partner’s equity in PassportCard and DavidShield. The gross purchase price for the 50% of DavidShield was $41.8 million, or $28.3 million net of the financing provided for the restructuring.

Kudu

On February 5, 2018, White Mountains entered into an agreement to fund up to $127.5 million in Kudu Investment Management, LLC (“Kudu”), a leading capital provider to asset management and wealth management firms. Kudu specializes in providing capital solutions to asset managers and registered investment advisers, including generational ownership transfers, management buyouts, acquisition and growth finance, as well as liquidity for legacy partners.

As of March 31, 2018, White Mountains has funded $1.8 million in Kudu. White Mountains has determined that Kudu is a VIE, however White Mountains is not the primary beneficiary. White Mountains has elected to take the fair value option for its investment in Kudu.

MediaAlpha

On October 5, 2017, MediaAlpha acquired certain assets associated with the Health, Life and Medicare insurance business of Healthplans.com for an aggregate purchase price of $28.0 million. The majority of assets acquired, which are included in other intangible assets, consist of customer relationships, a non-compete agreement from the seller and domain names. See Note 4 — “Goodwill and Other Intangibles Assets”.

On October 5, 2017, White Mountains acquired 131,579 newly-issued Class A common units of MediaAlpha for $12.5 million. As of March 31, 2018 and December 31, 2017 White Mountains’s ownership share in MediaAlpha was 62.3% and 64.4%.

Note 3. Investments Securities

White Mountains’s portfolio of investment securities held for general investment purposes consists of fixed maturity investments, short-term investments, common equity securities and other long-term investments, which are all classified as trading securities. Trading securities are reported at fair value as of the balance sheet date. Net realized and unrealized investment gains (losses) on trading securities are reported in pre-tax revenues.

White Mountains’s fixed maturity investments are generally valued using industry standard pricing methodologies. Key inputs include benchmark yields, benchmark securities, reported trades, issuer spreads, bids, offers, credit ratings and prepayment speeds. Income on mortgage 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 (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 interest-bearing 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, 2018 and December 31, 2017.

Other long-term investments consist primarily of hedge funds, private equity funds and unconsolidated private capital investments.

Net Investment Income

White Mountains’s net investment income is comprised primarily of interest income associated with White Mountains’s fixed maturity investments and short-term investments and dividend income from its common equity securities and other long-term investments.

The fair value of these investments is generally estimated using the NAV of the funds. As of March 31, 2018, White Mountains held investments in one hedge fund and ten private equity funds. The largest investment in a single fund was $56.4 million as of March 31, 2018 and $54.9 million as of December 31, 2017.

The following table presents investments in hedge funds and private equity funds by investment objective and sector as of March 31, 2018 and December 31, 2017:

Redemption of investments in certain hedge funds is subject to restrictions including lock-up periods where no redemptions or withdrawals are allowed, restrictions on redemption frequency and advance notice periods for redemptions. Amounts requested for redemptions remain subject to market fluctuations until the redemption effective date, which generally falls at the end of the defined redemption period. As of March 31, 2018, White Mountains held one active hedge fund with a fair value of $56.4 million. The hedge fund is subject to a lock-up period that expires on September 1, 2018, with a semi-annual restriction on redemption frequency thereafter and an advance notice period requirement of not less than 45 days.

White Mountains redeemed its one investment in a long/short equity REIT hedge fund having a fair value of $20.8 million as of December 31, 2017. The bulk of the redemption proceeds were received early in the first quarter of 2018 with the balance received in April of 2018.

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 its investors.

The following table presents investments in private equity funds that were subject to lock-up periods as of March 31, 2018:



Millions	1 – 3 years	3 – 5 years	5 – 10 years	>10 years	Total
Private equity funds — expected lock-up period remaining	$6.1	$6.2	$49.2	$12.7	$74.2

Fair Value Measurements as of March 31, 2018

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 or liabilities 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”). As of March 31, 2018 and December 31, 2017, White Mountains used quoted market prices or other observable inputs to determine fair value for approximately 92% and 94% of the investment portfolio.

Fair Value Measurements by Level

The following tables present White Mountains’s fair value measurements for investments as of March 31, 2018 and December 31, 2017 by level. The major security types were based on the legal form of the securities. 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 mortgage and asset-backed securities vary depending on the nature of the issuing entity type. White Mountains further disaggregates debt securities issued by corporations and common 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 Bloomberg Barclays U.S. Intermediate Aggregate and S&P 500 indices.

Mortgage and Asset-backed Securities

White Mountains purchases commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”) with the goal of maximizing risk adjusted returns in the context of a diversified portfolio.

White Mountains considers sub-prime mortgage-backed securities as those that have underlying loan pools that exhibit weak credit characteristics, or those that are issued from dedicated sub-prime shelves or dedicated second-lien shelf registrations (i.e., White Mountains considers investments backed primarily by second-liens to be sub-prime risks regardless of credit scores or other metrics). As of March 31, 2018 White Mountains did not hold any RMBS categorized as sub-prime.

White Mountains considers mortgage-backed securities as “non-prime” (also called “Alt A” or “A-”) if they are backed by collateral that has overall credit quality between prime and sub-prime based on White Mountains’s review of the characteristics of their underlying mortgage loan pools, such as credit scores and financial ratios. As of March 31, 2018, White Mountains did not hold any RMBS classified as non-prime.

The following table presents the carrying value of White Mountains’s mortgage and asset-backed securities as of March 31, 2018 and December 31, 2017:

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 and other long-term investments as of March 31, 2018 and 2017 consist of securities for which the estimated fair value has not been determined based upon quoted market price inputs for identical or similar securities.

The following tables present the changes in White Mountains’s fair value measurements by level for the three months ended March 31, 2018 and 2017:

Fair Value Measurements — Transfers Between Levels - Three-months ended March 31, 2018 and 2017

Transfers between levels are recorded using the fair value measurement as of the end of the quarterly period in which the event or change in circumstance giving rise to the transfer occurred.

During the first three months of 2018 and 2017, there were no fixed maturity investments or other long-term investments classified as Level 3 measurements in the prior period that were transferred to Level 2 measurements.

⁽¹⁾Effective rate considers the effect of the debt issuance costs.

WTM Bank Facility

On August 14, 2013, the Company entered into a revolving credit facility with a syndicate of lenders administered by Wells Fargo Bank, N.A., which has a total commitment of $425.0 million and has a maturity date of August 14, 2018 (the “WTM Bank Facility”). As of March 31, 2018, the WTM Bank Facility was undrawn.

The WTM Bank Facility contains various affirmative, negative and financial covenants which White Mountains considers to be customary for such borrowings, including certain minimum net worth and maximum debt to capitalization standards.

MediaAlpha Bank Facility

On May 12, 2017, MediaAlpha entered into a secured credit facility (the “MediaAlpha Bank Facility”) with Western Alliance Bank, which has a total commitment of $20.0 million and has a maturity date of May 12, 2020. On October 5, 2017, MediaAlpha refinanced the MediaAlpha Bank Facility in order to fund the acquisition of certain assets associated with the Health, Life and Medicare insurance business of Healthplans.com. The total commitment of the MediaAlpha Bank Facility was increased to $28.4 million and has a maturity date of October 6, 2020. The MediaAlpha Bank Facility consists of a $18.4 million term loan facility, which has an outstanding balance of $16.6 million as of March 31, 2018, and a revolving loan facility for $10.0 million, which has an outstanding balance of $5.0 million as of March 31, 2018.

The MediaAlpha Bank Facility carries a variable interest rate that is based on the Prime Rate, as published by the Wall Street Journal, plus a spread of 1.5% on the term loan facility and 0.25% on the revolving credit facility as of March 31, 2018.

During the three months ended March 31, 2018, MediaAlpha repaid $1.3 million on the term loan and $1.0 million on the revolving loan under the MediaAlpha Bank Facility.

The MediaAlpha Bank Facility is secured by intellectual property and the common stock of MediaAlpha’s subsidiaries, and contains various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including a fixed charge coverage ratio and an asset coverage ratio.

Compliance

At March 31, 2018, White Mountains was in compliance with the covenants under all of its debt instruments.

Note 6. Income Taxes

The Company and its Bermuda domiciled subsidiaries are not subject to Bermuda income tax under current Bermuda law. If 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 subsidiaries and branches are subject to tax are Barbados, Gibraltar, Ireland, Israel, Luxembourg, the United Kingdom and the United States.

White Mountains’s income tax expense related to pre-tax loss from continuing operations for the three months ended March 31, 2018 represented an effective tax rate of (1.1)%. The effective tax rate was different from the U.S. statutory rate of 21%, primarily due to a full valuation allowance on all net deferred tax assets at U.S. operations, withholding taxes and a tax benefit recorded at BAM. For BAM, member surplus contributions (“MSC”) and the related taxes thereon are recorded directly to non-controlling interest equity, while the valuation allowance on such taxes is recorded through the income statement. For the three months ended March 31, 2018, BAM recorded a tax benefit of $0.6 million associated with the valuation allowance on taxes related to MSC that is included in the effective tax rate.

White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the three months ended March 31, 2017 represented an effective tax rate of 8.3%. The effective tax rate was different from the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all net deferred tax assets at U.S. operations and a tax benefit recorded at BAM. For BAM, MSC and the related taxes thereon are recorded directly to non-controlling interest equity, while the valuation allowance on such taxes is recorded through the income statement. For the three months ended March 31, 2017, BAM recorded a tax benefit of $2.7 million associated with the valuation allowance on taxes related to MSC that is included in the effective tax rate.

In arriving at the effective tax rate for the three months ended March 31, 2018 and 2017, 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, 2018 and 2017.

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.

With few exceptions, White Mountains is no longer subject to U.S. federal, state, or non-U.S. income tax examinations by tax authorities for years before 2013.

Note 7. Derivatives

White Mountains’s investment portfolio includes investments denominated in Japanese Yen, Euros, GBP and other foreign currencies. White Mountains previously entered into foreign currency forward contracts to manage its foreign currency exposure related to these investments. In the first quarter of 2018, in conjunction with the liquidation of the GBP investment grade corporate bond mandate, White Mountains closed the associated foreign currency forward contract. White Mountains no longer has any open foreign currency forward contracts. As of December 31, 2017, White Mountains held $206.3 million total gross notional value of a foreign currency forward contract with a carrying value of $(3.7) million.

The derivative (losses) gains recognized in net realized and unrealized investment gains (losses) for the three months ended March 31, 2018 and 2017 were $(3.5) million and $3.0 million.

Note 8. 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, 2018, 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. At inception, BAM and HG Re also entered into a first loss reinsurance treaty (“FLRT”). HG Re provides first loss reinsurance protection up to 15% of par outstanding on each municipal bond insured by BAM. In return, BAM cedes 60% of the risk premium charged for insuring the municipal bond, net of a ceding commission. During 2017, HG Global and BAM made certain changes to the ceding commission arrangements under the FLRT. These changes serve to accelerate growth in BAM's statutory capital but do not impact the net risk premium ceded from BAM to HG Re. 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.

The interest rate on the BAM Surplus Notes for the five years ending December 31, 2018 is a variable rate equal to the one-year U.S. treasury rate plus 300 basis points, set annually, which is 4.60% for 2018 and was 3.54% for 2017. 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 8.0%. No payment of interest or principal on the BAM Surplus Notes may be made without the approval of the New York State Department of Financial Services (“NYDFS”). BAM has stated its intention to seek regulatory approval to pay interest and principal on its surplus notes only to the extent that its remaining qualified statutory capital and other capital resources continue to support its outstanding obligations, business plan and its AA stable rating from S&P. BAM repaid $4.0 million of the BAM Surplus Notes and $1.0 million of the related accrued interest during the year ended December 31, 2017. There were no repayments for the three months ended March 31, 2018.

In order to further support BAM’s long-term capital position and business prospects, in 2017 HG Global agreed to contribute the $203.0 million of Series A BAM Surplus Notes (“Series A Notes”) into the supplemental collateral trust (the “Supplemental Trust”) at HG Re. The Supplemental Trust already held the $300.0 million of Series B BAM Surplus Notes (“Series B Notes”). Assets held in the Supplemental Trust serve to collateralize HG Re’s obligations to BAM under the FLRT. HG Global and BAM also changed the payment terms of the Series B Notes, so that payments will reduce principal and accrued interest on a pro rata basis, consistent with the payment terms on the Series A Notes. The terms of the Series B Notes had previously stipulated that payments would first reduce interest owed, then reduce principal owed once all accrued interest had been paid. The Supplemental Trust target balance is equal to approximately $603.0 million. As the BAM Surplus Notes are repaid over time, the BAM Surplus Notes will be replaced in the Supplemental Trust by cash and fixed income securities. The collateral trust balances must be at target levels before capital can be distributed out of the Supplemental Trust. In connection with the contribution, the Series A Notes were merged with the Series B Notes.

As of March 31, 2018 and December 31, 2017, the collateral trusts held assets of $721.9 million and $715.1 million, which both included $499.0 million of BAM Surplus Notes. As of March 31, 2018 and December 31, 2017, HG Global has accrued $131.7 million and $126.0 million of interest receivable on the BAM Surplus Notes.

The following table presents a schedule of BAM’s insured obligations:

Note 9. Earnings Per Share

White Mountains calculates earnings per share using the two-class method, which allocates earnings between common shares and unvested restricted common shares. Both classes of shares participate equally in dividends and earnings on a per share basis. Basic earnings per share amounts are based on the weighted average number of common shares outstanding adjusted for unvested restricted common shares.

The following table presents the Company’s computation of earnings per share from continuing operations for the three months ended March 31, 2018 and 2017. See Note 16 — “Held for Sale and Discontinued Operations”.

Note 10. Employee Share-Based Incentive Compensation Plans

White Mountains’s Long-Term Incentive Plan (the “WTM Incentive Plan”) provides for grants of various types of share-based and non share-based incentive awards to key employees of White Mountains. As of March 31, 2018, White Mountains’s share-based compensation incentive awards consist of performance shares and restricted shares.

Performance Shares

Performance shares are conditional grants of a specified maximum number of common shares or an equivalent amount of cash. Awards generally vest at the end of a three-year period, are subject to the attainment of pre-specified performance goals, and are valued based on the market value of common shares at the time awards are approved for payment.

The following table presents the performance share activity for the three months ended March 31, 2018 and 2017 for performance shares granted under the WTM Incentive Plan:

White Mountains’s investments in unconsolidated entities are included within other long-term investments and consist of investments in common equity securities or similar instruments, which give White Mountains the ability to exert significant influence over the investee’s operating and financial policies (“equity method eligible unconsolidated entities”). Such investments may be accounted for under either the equity method or, alternatively, White Mountains may elect to account for them under the fair value option.

The following table presents the carrying values of investments in equity method eligible unconsolidated entities recorded within other long-term investments:

Note 14. Fair Value of Financial Instruments

White Mountains accounts for all its financial instruments at fair value with the exception of the WTM Bank Facility, which was undrawn at March 31, 2018 and December 31, 2017, and the MediaAlpha Bank Facility, which is recorded as debt at face value less unamortized original issue discount.

The following table presents the fair value and carrying value of this financial instrument as of March 31, 2018 and December 31, 2017:

MediaAlpha Bank Facility	$	21.8	$	21.6	$	23.9	$	23.8

The fair value estimate for the MediaAlpha Bank Facility has been determined based on a discounted cash flows approach and is considered to be a Level 3 measurement.

Note 15. Contingencies

Legal Contingencies

White Mountains is subject to litigation and arbitration in the normal course of business. White Mountains considers the requirements of ASC 450 when evaluating its exposure to 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. White Mountains does not have any current litigation that may have a material adverse effect on White Mountains’s financial condition, results of operations or cash flows.

The following description presents significant legal contingencies, ongoing non-claims related litigation or arbitration as of March 31, 2018:

Sirius Tax Contingencies

A subsidiary of Sirius Group, which was sold by White Mountains in 2016, has been denied interest deductions by the Swedish Tax Authority (“STA”) for tax years 2013-2016. The Swedish subsidiary has filed an appeal in the Swedish Administrative Court for tax year 2013 and will preserve its right to contest the STA’s decision for later years if needed. Sirius Group believes it is more likely than not that it will prevail in the court proceedings. However, if the ultimate decision in the Swedish courts is unfavorable, White Mountains would be required to indemnify Sirius Group for the tax effect of the interest deductions, which is approximately $18.5 million.

Note 16. Held for Sale and Discontinued Operations

OneBeacon

On September 28, 2017, Intact Financial Corporation completed its acquisition of OneBeacon in an all-cash transaction for $18.10 per share. White Mountains received total proceeds of $1.3 billion and recorded a gain of $554.6 million, net of transaction costs. Net income from discontinued operations related to OneBeacon was $32.3 million for the three months ended March 31, 2017.

Tranzact

On July 21, 2016, White Mountains completed its sale of Tranzact to Clayton, Dubilier & Rice, LLC and received net proceeds of $221.3 million at closing. On October 5, 2016, White Mountains received additional proceeds of $1.2 million following the release of the post-closing purchase price adjustment escrow. During 2016, White Mountains recorded a $51.9 million gain from the sale of Tranzact in discontinued operations, which included a $30.2 million tax expense for the reversal of a tax valuation allowance that is offset by a tax benefit recorded in continuing operations.

During the three months ended March 31, 2017, White Mountains recorded a $1.0 million reduction to the gain from sale of Tranzact in discontinued operations as a result of 2016 state tax payments.

Sirius Group

On April 18, 2016, White Mountains completed the sale of Sirius Group to CMI for $2.6 billion. During 2016, White Mountains recorded a $363.2 million gain from the sale of Sirius Group in discontinued operations in the statement of operations and $113.3 million in other comprehensive income from discontinued operations.

During the three months ended March 31, 2018, White Mountains recorded a $0.1 million gain from sale of Sirius Group as a result of a change to the valuation of the accrued incentive compensation payable to Sirius Group employees.

Other

As of December 31, 2017, White Mountains has classified its Guilford, Connecticut property, which consists of an office building and adjacent land, as held for sale. The property has been measured at its estimated fair value net of costs of disposal, of $3.3 million as of March 31, 2018 and December 31, 2017.

Net Income (Loss) from Discontinued Operations

The following table presents the results of operations, including related income taxes, associated with the business classified as discontinued operations. For the three months ended March 31, 2018, the amounts presented relate to Sirius Group. For the three months ended March 31, 2017, the amounts presented relate to OneBeacon and Tranzact. The results of discontinued operations from Sirius Group and Tranzact up to the closing date of the transaction inured to White Mountains. Given the fixed price nature of the OneBeacon Transaction, OneBeacon’s results were economically transferred to the buyer at signing.

Earnings Per Share from Discontinued Operations

White Mountains calculates earnings per share using the two-class method, which allocates earnings between common and unvested restricted common shares. Both classes of shares participate equally in earnings on a per share basis. Basic earnings per share amounts are based on the weighted average number of common shares outstanding adjusted for unvested restricted common shares. Diluted earnings per share amounts are also impacted by the net effect of potentially dilutive common shares outstanding.

The following table presents the Company’s computation of earnings per share for discontinued operations for the three months ended March 31, 2018 and 2017:



	Three Months Ended
	March 31,
	2018			2017
Basic and diluted earnings per share numerators (in millions):
Net income attributable to White Mountains’s common shareholders	$	(48.0	)	$	29.0

Diluted earnings per share denominator (in thousands):
Total average common shares outstanding during the period	3,746.1			4,564.6
Average unvested restricted common shares ⁽³⁾	(35.9		)	(52.5		)

Basic earnings per share (in dollars) - discontinued operations:	$	.03		$	6.86
Diluted earnings per share (in dollars) - discontinued operations:	$	.03		$	6.86

⁽¹⁾Restricted shares issued by White Mountains contain dividend participation features, and therefore, are considered participating securities.

⁽²⁾Net earnings attributable to White Mountains’s common shareholders, net of restricted share amounts, is equal to undistributed earnings for the three months ended March 31, 2018 and 2017.

⁽³⁾ Restricted common shares outstanding vest either in equal annual installments or upon a stated date. See Note 10 — “Employee Share-Based Incentive Compensation Plans”.

Note 17. Financial Statement Revisions

In October 2017, White Mountains discovered that the former CEO of Wobi, one of its overseas portfolio companies, had been reporting overstated commission revenues and related receivables to White Mountains. Upon discovery of the overstatements, White Mountains initiated an investigation, conducted by outside counsel, of the reporting of these overstatements by Wobi to White Mountains. As a result of this investigation, White Mountains has revised certain of its previously issued financial statements. The revisions resulted in reductions to commission revenues (included in advertising and commission revenues) and commissions receivable (included in other assets). In addition, the overstatements led White Mountains to write down the goodwill and other intangible assets related to Wobi to zero. Wobi also conducted a separate investigation with the assistance of Israeli counsel to support the preparation of Wobi’s standalone financial statements. That separate investigation has been completed and its results did not materially impact White Mountains’s financial statements.

White Mountains evaluated the impact of the misstatements resulting from the overstatements at Wobi on prior periods’ financial statements in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 1.M, Materiality, and concluded the misstatements were not material to any previously reported financial statements. However, while not material to any previously reported annual or quarterly period, the aggregate amount of prior period misstatements could be material to White Mountains's results for the full fiscal year ended December 31, 2017. White Mountains has therefore revised all periods impacted including its consolidated balance sheet as of March 31, 2017 and its consolidated statements of operations and comprehensive income, consolidated statements of changes in equity, cash flows and earnings per share for the three months March 31, 2017. The impact of these revisions to each of the previously reported consolidated statements are disclosed below.

Amounts previously reported reflect the reclassification of OneBeacon to discontinued operations for all applicable periods presented.

There was no change to cash flows from operations, cash flows from investing activities or cash flows from financing activities.

Note 18. Subsequent Events

NSM

On April 2, 2018, White Mountains announced it had entered into an agreement to acquire 95% of NSM Insurance Group (“NSM”) for cash in an amount equal to $368.3 million, subject to certain adjustments. NSM expects to borrow approximately $100.0 million of third party indebtedness in conjunction with the acquisition which will reduce White Mountains’s net investment to approximately $273.3 million. The transaction is subject to regulatory approvals and other customary closing conditions and is expected to close by the end of the second quarter of 2018.

Fidus Re

In April 2018, BAM expanded its claims paying resources by $100.0 million through a collateralized reinsurance agreement with Fidus Re Ltd., a special-purpose insurer created solely to provide collateralized reinsurance protection to BAM.

Tender Offer

On April 10, 2018, White Mountains commenced a modified Dutch tender offer for up to 500,000 White Mountains common shares that will expire on May 7, 2018.


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 include three non-GAAP financial measures (i) adjusted book value per share, (ii) adjusted capital, and (iii) adjusted earnings before interest, taxes, depreciation and amortization, and non-cash equity-based compensation expense (“Adjusted EBITDA”), that have been reconciled from their most comparable GAAP financial measures on page 56. White Mountains believes these measures to be useful in evaluating White Mountains’s financial performance and condition.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2018 AND 2017

Overview

White Mountains is engaged in the business of making opportunistic and value-oriented acquisitions of businesses and assets in the insurance, financial services and related sectors, operating these businesses and assets through our subsidiaries and, if and when attractive exit valuations become available, disposing of these businesses and assets.

White Mountains ended the first quarter of 2018 with book value per share of $916 and adjusted book value per share of $903. Book value per share and adjusted book value per share decreased 2% and 1% for the quarter, including dividends. The decreases were driven primarily by investment results.

Gross written premiums and MSC in the HG Global/BAM segment totaled $11 million in the first quarter of 2018, compared to $28 million in the first quarter of 2017, reflecting a market-wide drop in new-issue municipal volume, as the uncertainty over tax reform caused many issuers to pull forward planned 2018 issuance volume into 2017. BAM insured municipal bonds with par value of $1.3 billion in the first quarter of 2018, compared to $2.4 billion in the first quarter of 2017. Total pricing, which is premiums plus MSC, including the present value of future installment MSC not yet collected, weighted by the par value of municipal bonds insured, was 96 basis points in the first quarter of 2018, compared to 119 basis points in the first quarter of 2017. Pricing in the primary market increased to 72 basis points in the first quarter of 2018, up from 59 basis points in the first quarter of 2017. BAM’s total claims paying resources were $709 million at March 31, 2018, compared to $708 million at December 31, 2017 and $662 million at March 31, 2017.

MediaAlpha reported break-even GAAP pre-tax income and adjusted EBITDA of $10 million in the first quarter of 2018, compared to GAAP pre-tax loss of $1 million and adjusted EBITDA of $2 million in the first quarter of 2017. MediaAlpha reported revenues of $72 million in the first quarter of 2018, compared to $33 million in the first quarter of 2017. The increases in GAAP pre-tax income, adjusted EBITDA and revenues were primarily driven by growth in the P&C vertical and the Health, Medicare and Life vertical, (which includes the impact of the acquisition of assets from Healthplans.com in the fourth quarter of 2017). Also in the first quarter of 2018, MediaAlpha recognized $6 million of non-cash equity-based compensation expense that is excluded from adjusted EBITDA.

The pre-tax total return on invested assets was -1.0% in the first quarter of 2018 compared to 1.5% in the first quarter of 2017. White Mountains’s fixed income portfolio returned -0.7% for the first quarter of 2018 and 0.9% for the first quarter of 2017, outperforming the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index returns of -1.1% and 0.7%. White Mountains’s portfolio of common equity securities returned -0.9% for the first quarter of 2018, and 6.1% for the first quarter of 2017, essentially in-line with the S&P 500 Index returns of -0.8% and 6.1%. Other long-term investments were down -2.8% for the first quarter of 2018, principally driven by losses from currency hedges, which have since been closed out in connection with the liquidation of White Mountains's sterling-denominated bond portfolio. White Mountains’s other long-term investments portfolio returned 1.0% for the first quarter of 2017. The results were primarily attributable to favorable private equity fund returns, partially offset by unfavorable results from unconsolidated private capital investments, unfavorable mark-to-market adjustments to the OneBeacon surplus notes and losses from foreign currency forward contracts.

Subsequent Events

NSM

On April 2, 2018, White Mountains announced an agreement to acquire 95% of NSM for cash in an amount equal to $368 million, subject to certain adjustments. NSM expects to borrow approximately $100 million of third party indebtedness in conjunction with the acquisition which will reduce White Mountains’s net investment to approximately $273 million. NSM is a full-service MGU and program administrator for specialty property & casualty insurance, with over $500 million of controlled premiums. NSM manages all aspects of the placement process on behalf of its carrier partners, including product development, marketing, underwriting, policy issuance, and claims. The company specializes in niche sectors such as collector cars, social services and behavioral health, specialty real estate, sports and fitness centers, and pet insurance.

Fidus Re

In April 2018, BAM expanded its claims-paying resources by $100 million through a collateralized reinsurance agreement with Fidus Re Ltd., a special-purpose insurer created solely to provide collateralized excess-of-loss reinsurance protection to BAM.

Tender Offer

On April 10, 2018, White Mountains commenced a modified Dutch tender offer for up to 500,000 White Mountains common shares that will expire on May 7, 2018.

Adjusted Book Value Per Share

During the second quarter of 2017, White Mountains changed its calculation of adjusted book value per share (i) to include a discount for the time value of money arising from the expected timing of cash payments of principal and interest on the BAM Surplus Notes and (ii) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. See NON-GAAP FINANCIAL MEASURES on page 56.

The following table presents White Mountains’s book value per share and reconciles it to adjusted book value per share, a non-GAAP measure.

HG Global/BAM Results—Three Months Ended March 31, 2018 versus Three Months Ended March 31, 2017

BAM reports on a statutory accounting basis to the NYDFS and does not report stand-alone GAAP financial results. BAM is owned by its members, the municipalities that purchase BAM’s insurance for their debt issuances. BAM charges an insurance premium on each municipal bond insurance policy it writes. A portion of the premium is a MSC and the remainder is a risk premium. In the event of a municipal bond refunding, the MSC from the original issuance can be reutilized, in effect serving as a credit against the total insurance premium on the refunding of the municipal bond. Issuers of debt insured by BAM are members of BAM so long as any of their BAM-insured debt is outstanding, and as members they have certain interests in BAM, including the right to vote for BAM’s directors and to receive dividends in the future, if declared.

Written premiums and MSC in the HG Global/BAM segment were $11 million in 2018, compared to $28 million in 2017, primarily due to a market wide decrease in new issuance volume, as the uncertainty over tax reform caused many issuers to pull forward planned 2018 issuance volume into 2017. Under tax laws effective in 2018, interest income received by investors on new bonds that are issued to refinance existing municipal bonds and are issued more than 90 days before the refinanced municipal bond is scheduled to be redeemed (“advance refundings”) are now treated as taxable income to the investor.

Total pricing, which is premiums plus MSC, including the present value of future installment MSC not yet collected, weighted by the par value of municipal bonds insured, was 96 basis points in 2018, down from 119 basis points in 2017. Pricing in the primary market increased to 72 basis points in the first quarter of 2018, up from 59 basis points in the first quarter of 2017. In the first quarter of 2018, BAM insured $1.3 billion of municipal bonds, $1.1 billion of which were in the primary market, compared to $2.4 billion of municipal bonds, $2.0 billion of which were in the primary market, insured in the first quarter of 2017.

The following table presents the gross par value of primary and secondary market policies issued, the gross written premiums plus MSC and total pricing for the three months ended March 31, 2018 and 2017:



	Three Months Ended March 31,
$ in millions	2018		2017
Gross par value of primary market policies issued	$	1,149.5	$	2,041.0
Gross par value of secondary market policies issued	148.6		338.1
Total gross par value of market policies issued	$	1,298.1	$	2,379.1
Gross written premiums	$	6.4	$	18.7
MSC collected	4.9		9.6
Total gross written premiums and MSC	$	11.3	$	28.3
Total pricing⁽¹⁾	96 bps		119 bps

⁽¹⁾ Total pricing also includes the present value of future installment MSC not yet collected of $1.2 for the first quarter of March 31, 2018.

HG Global reported GAAP pre-tax income of $5 million in the first quarter of 2018, compared to $7 million the first quarter of 2017. The decrease in pre-tax income was primarily due to lower returns in HG Global's investment portfolio. Results for the first quarter of 2018 include $6 million of interest income on the BAM Surplus Notes, compared to $5 million of interest income in the first quarter of 2017.

BAM is a mutual insurance company that is owned by its members. BAM’s results are consolidated into White Mountains’s GAAP financial statements and attributed to non-controlling interests. White Mountains reported $19 million of GAAP pre-tax loss from BAM in the first quarter of 2018, compared to $12 million in the first quarter of 2017. The increase in pre-tax loss was primarily due to lower returns in BAM's investment portfolio. Results for the first quarter of 2018 include $6 million of interest expense on the BAM Surplus Notes and $11 million of operating expenses, compared to $5 million of interest expense and $10 million of operating expenses in the first quarter of 2017.

BAM’s “claims paying resources” represent the capital and other financial resources BAM has available to pay claims and, as such, is a key indication of BAM’s financial strength. BAM’s claims paying resources include BAM’s qualified statutory capital, including MSC, net unearned premiums, contingency reserves, present value of future installment premiums and MSC and the first loss reinsurance protection provided by HG Re, which is collateralized and held in trusts.

As of March 31, 2018, BAM’s claims paying resources increased to $709 million from $708 million as of December 31, 2017. The increase was primarily driven by a $2 million increase in present value of future installment premiums and MSC and a $1 million increase in the collateral trusts at statutory value, partially offset by a $3 million decrease in qualified statutory capital.

The following table presents BAM’s total claims paying resources as of March 31, 2018 and December 31, 2017:



Millions	March 31, 2018		December 31, 2017
Policyholders’ surplus	$	420.9	$	427.3

Present value of future installment premiums and MSC	10.9		9.0
Collateral trusts at statutory value	208.2		206.8
Claims paying resources	$	708.9	$	708.4

As of March 31, 2017, BAM’s claims paying resources increased to $662 million from $644 million as of December 31, 2016. The increase was primarily driven by a $12 million increase in the collateral trusts at statutory value and an increase of $6 million in net unearned statutory premiums.

The following table presents BAM’s total claims paying resources as of March 31, 2017 and December 31, 2016:

MediaAlpha Results—Three Months Ended March 31, 2018 versus Three Months Ended March 31, 2017

MediaAlpha reported break-even GAAP pre-tax income and adjusted EBITDA of $10 million in the first quarter of 2018, compared to GAAP pre-tax loss of $1 million and adjusted EBITDA of $2 million in the first quarter of 2017. MediaAlpha reported revenues of $72 million in the first quarter of 2018, compared to $33 million in first quarter of 2017. The increase in GAAP pre-tax income, adjusted EBITDA and revenues were primarily driven by $19 million of revenue growth in MediaAlpha’s P&C verticals, driven by increased volume from key strategic publishers and improving demand from advertisers, and $12 million of revenue growth in the Health, Medicare and Life verticals, driven by strong contributions from assets acquired from Healthplans.com in the fourth quarter of 2017.

MediaAlpha’s cost of sales is comprised primarily of revenue share based payments to partners. Cost of sales were $57 million in the first quarter of 2018, compared to $28 million in the first quarter of 2017. The 104% increase in cost of sales was driven by the 118% increase in revenue. MediaAlpha's general and administrative expenses were $11 million in the first quarter of 2018, compared to $3 million in the first quarter of 2017. The increase was primarily driven by the recognition of non-cash equity-based compensation expense of $6 million.

Other Operations Results—Three Months Ended March 31, 2018 versus Three Months Ended March 31, 2017

White Mountains’s Other Operations segment reported pre-tax loss of $52 million in the first quarter of 2018, compared to pre-tax income of $3 million in the first quarter of 2017. The change was driven primarily by lower investment returns in the first quarter of 2018, partially offset by a reduction in general and administrative expenses. White Mountains’s Other Operations segment reported $46 million of net realized and unrealized investment losses in the first quarter of 2018, compared to $35 million of net realized and unrealized investment gains in the first quarter of 2017. White Mountains’s Other Operations segment reported $16 million of net investment income in the first quarter of 2018 compared to net investment income of $10 million in the first quarter of 2017. The increase was primarily due to dividend income on common equity securities. See Summary of Investment Results on page 48. White Mountains’s Other Operations segment general and administrative expenses were $22.0 million in the first quarter of 2018, compared to $45 million in the first quarter of 2017. The first quarter of 2017 included $14 million of additional compensation expense related to the retirement of the Company’s former Chairman and CEO and higher incentive compensation costs primarily due to a 5% increase in the market price of White Mountains's common shares during the first quarter of 2017 compared to a 3% decrease in the market price in the first quarter of 2018.

Investment Returns—Three Months Ended March 31, 2018 versus Three Months Ended March 31, 2017

White Mountains’s pre-tax total return on invested assets was -1.0% for the first quarter of 2018 compared to 1.5% for the first quarter of 2017. The returns for the first quarter of 2018 were driven primarily by rising interest rates and declines in equity markets. The returns for the first quarter of 2017 were driven primarily by the equity market rally that followed the U.S. presidential election.

Fixed Income Results

White Mountains maintains a high quality, short-duration fixed income portfolio. As of March 31, 2018, the fixed income portfolio duration, including short-term investments, was 2.8 years compared to 3.4 years as of December 31, 2017 and 2.9 years as of March 31, 2017. The decrease in the duration of the fixed income portfolio over this period was primarily a result of the liquidation of the medium duration GBP investment grade corporate bond mandate in the first quarter of 2018.

White Mountains’s fixed income portfolio returned -0.7% for the first quarter of 2018, outperforming the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of -1.1% as interest rates rose during the period. White Mountains’s fixed income portfolio returned 0.9% for the first quarter of 2017, outperforming the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of 0.7%.

In the fourth quarter of 2017, White Mountains established a U.S. investment grade corporate bond portfolio with Principal Global Investors, LLC (“Principal”), a third party manager. As of March 31, 2018, the fair value of the Principal investment grade corporate bond investments was $242 million and the duration of the Principal investment grade corporate bond portfolio was approximately 4.4 years.

In the fourth quarter of 2016, White Mountains established a medium duration GBP investment grade corporate bond mandate with Legal & General Investment Management, Ltd. (“LGIM”), a third-party manager. White Mountains also entered into a foreign currency forward contract, which was recorded in other long-term investments, to manage its GBP foreign currency exposure relating to this mandate. In the first quarter of 2018, White Mountains liquidated the LGIM portfolio and closed the associated foreign currency forward contract.

In the third quarter of 2016, White Mountains established a relatively concentrated portfolio of high-yield fixed maturity investments managed by Principal. The portfolio is invested in issuers of U.S. dollar denominated publicly traded and 144A debt securities issued by corporations with generally at least one rating between “B-” and “BB+” inclusive by S&P or similar ratings from other rating agencies. As of March 31, 2018, the fair value of the Principal high-yield fixed maturity investments was $200 million and the duration of the Principal high-yield portfolio was approximately 4.6 years.

Common Equity Securities and Other Long-Term Investments Results

White Mountains maintains a portfolio of common equity securities and other long-term investments. White Mountains’s management believes that prudent levels of investments in common equity securities and other long-term investments are likely to enhance long-term after-tax total returns.

White Mountains’s portfolio of common equity securities and other long-term investments returned -1.2% for the first quarter of 2018 and 4.2% for the first quarter of 2017. White Mountains’s portfolio of common equity securities and other long-term investments represented approximately 36%, 32% and 17% of total invested assets as of March 31, 2018, December 31, 2017 and March 31, 2017. The increase in the percentage of this portfolio is primarily attributable to management’s decision to add equity exposure over the period and a decline in the investment asset base due to the OneBeacon Transaction and share repurchase activity.

White Mountains’s portfolio of common equity securities primarily consists of passive ETFs and publicly-traded common equity securities that are actively managed by third party managers. White Mountains’s portfolio of common equity securities returned -0.9% for the first quarter of 2018, essentially in-line with the S&P 500 Index return of -0.8%. White Mountains’s portfolio of common equity securities returned 6.1% for the first quarter of 2017, also in-line with the S&P 500 Index return of 6.1%.

White Mountains’s portfolio of ETFs seeks to provide investment results that, before expenses, generally correspond to the performance of broad market indices. As of March 31, 2018 and December 31, 2017, White Mountains had approximately $653 million and $570 million invested in ETFs. In the first quarter of 2018 and 2017, the ETFs essentially earned the effective index return, before expenses, over the period in which White Mountains was invested in these funds.

White Mountains’s third party common equity manager relationships (the “actively managed common equity portfolios”) have been with Silchester International Investors (“Silchester”), who invests in value-oriented non-U.S. equity securities through a unit trust, and Lateef Investment Management, a growth at a reasonable price adviser managing a highly concentrated portfolio of mid-cap and large-cap growth companies. During the first quarter of 2017, White Mountains established a new third-party manager relationship with Lazard Asset Management (“Lazard”), to manage a Pan-European common equity portfolio, of which the majority of the securities are denominated in Euros. In September 2017, White Mountains terminated its relationship with Lazard in order to concentrate its non-U.S. equity exposure in small to mid-cap international equities through other third-party managers. During the third quarter of 2017 and prior to terminating Lazard, White Mountains established a new third-party manager relationship with Highclere International Investors (“Highclere”), who invests in small to mid-cap equity securities listed in markets outside of the United States and Canada through a unit trust.

White Mountains’s actively managed common equity portfolios returned -0.4% for the first quarter of 2018 and 6.9% for the first quarter 2017, outperforming the S&P 500 Index return of -0.8% and 6.1% for the comparable periods.

White Mountains entered into foreign currency forward contracts, which were recorded in other long-term investments, to manage its foreign currency exposure relating to the common equity portfolio managed by Lazard and a portion of the common equity portfolios managed by Silchester and Highclere. These foreign currency forward contracts were closed as of December 31, 2017.

White Mountains maintains a portfolio of other long-term investments that primarily consists of one hedge fund, private equity funds and unconsolidated private capital investments. As of March 31, 2018, approximately 52% of these other long-term investments were in one long-short hedge fund and ten private equity funds, with a general emphasis on narrow, sector-focused funds.

White Mountains’s other long-term investments portfolio returned -2.8% for the first quarter of 2018. The results were primarily attributable to losses from the foreign currency forward contract closed during the period and unfavorable results from unconsolidated private capital investments. White Mountains’s other long-term investments portfolio returned 1.0% for the first quarter of 2017. The results were primarily attributable to favorable private equity fund returns, partially offset by unfavorable results from unconsolidated private capital investments, unfavorable mark-to-market adjustments to the OneBeacon surplus notes and losses from foreign currency forward contracts.

Foreign Currency Translation

As of March 31, 2018, White Mountains had gross foreign currency exposure on approximately $233 million of net assets relating to common equity securities managed by Silchester and Highclere and various other consolidated and unconsolidated private capital investments.

White Mountains may enter into foreign currency forward contracts to mitigate its foreign currency exposure on certain invested assets. In the fourth quarter of 2017, White Mountains closed the foreign currency forward contracts associated with the investment assets managed by Silchester and Highclere. In the first quarter of 2018, in conjunction with the liquidation of the GBP investment grade corporate bond mandate, White Mountains closed the associated foreign currency forward contract.

The following table presents the fair value of White Mountains’s foreign denominated assets as of March 31, 2018:



Currency ⁽¹⁾ $ in millions	Fair Value		% of Common Shareholders’ Equity

Total	$	233.2	6.8	%

⁽¹⁾ Includes net assets of Wobi and Buzzmove.

Income Taxes

White Mountains’s income tax expense related to pre-tax loss from continuing operations for the three months ended March 31, 2018 represented an effective tax rate of (1.1)%. The effective tax rate was different from the U.S. statutory rate of 21%, primarily due to a full valuation allowance on all net deferred tax assets at U.S. operations, withholding taxes and a tax benefit recorded at BAM. For BAM, MSC and the related taxes thereon are recorded directly to non-controlling interest equity, while the valuation allowance on such taxes is recorded through the income statement. For the three months ended March 31, 2018, BAM recorded a tax benefit of $1 million associated with the valuation allowance on taxes related to MSC that is included in the effective tax rate. See Note 6 — “Income Taxes”.

White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the three months ended March 31, 2017 represented an effective tax rate of 8.3%. The effective tax rate was different from the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all net deferred tax assets at U.S. operations and a tax benefit recorded at BAM. For BAM, MSC and the related taxes thereon are recorded directly to non-controlling interest equity, while the valuation allowance on such taxes is recorded through the income statement. For the three months ended March 31, 2017, BAM recorded a tax benefit of $3 million associated with the valuation allowance on taxes related to MSC that is included in the effective tax rate. See Note 6 — “Income Taxes”.

Discontinued Operations

OneBeacon

On September 28, 2017, White Mountains received $1.3 billion in cash proceeds from the OneBeacon Transaction and recorded a gain of $555 million, net of transaction costs. As a result of the OneBeacon Transaction, OneBeacon’s results have been reported as discontinued operations within White Mountains’s GAAP financial statements. In the first quarter of 2017, White Mountains reported net income of $32 million from OneBeacon in discontinued operations. See Note 16 — “Held for Sale and Discontinued Operations”.

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 operating subsidiaries, capital raising activities, net investment income, proceeds from sales, repayments and maturities of investments and, from time to time, proceeds from 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, distributions to non-controlling interest holders of 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 reinsurance and other operating subsidiaries are expected to be premium and fee collections, net investment income, proceeds from sales, repayments and maturities of investments, contributions from holding companies, capital raising activities and, from time to time, proceeds from sales of operating subsidiaries. The primary uses of cash are expected to be loss payments, policy acquisition and other underwriting costs, cost of sales, 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. Premium and fee levels, loss payments, cost of sales and investment returns may be impacted by changing rates of inflation and other economic conditions. Some time 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 losses and benefits cannot be predicted with certainty. White Mountains’s reinsurance subsidiary maintains a portfolio of invested assets with varying maturities and a substantial amount of cash and short-term investments to provide adequate liquidity for the payment of losses.

Management believes that White Mountains’s cash balances, cash flows from operations and routine sales and maturities of investments are adequate to meet expected cash requirements for the foreseeable future on both a holding company and subsidiary level.

Dividend Capacity

Following is a description of the dividend capacity of White Mountains’s reinsurance and other operating subsidiaries:

HG Global/BAM

At March 31, 2018, HG Global had $619 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 quarter of 2018. As of March 31, 2018, HG Global has accrued $248 million of dividends payable to holders of its preferred shares, $240 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 to amounts held outside of the collateral trusts pursuant to the FLRT with BAM. As of March 31, 2018, HG Re had statutory capital and surplus of $681 million, $722 million of assets held in the collateral trusts pursuant to the FLRT with BAM and less than $1 million of cash and investments outside the collateral trusts.

BAM repaid $4.0 million of the BAM Surplus Notes and $1.0 million of the related accrued interest during the year ended December 31, 2017. There were no repayments for the three months ended March 31, 2018.

MediaAlpha

During the first three months of 2018, MediaAlpha did not pay any dividends to its shareholders. As of March 31, 2018, MediaAlpha had $16 million of net unrestricted cash.

Other Operations

During the first quarter of 2018, White Mountains paid a $4 million common share dividend. As of March 31, 2018, the Company and its intermediate holding companies had $1,470 million of net unrestricted cash, short-term investments and fixed maturity investments, $946 million of common equity securities and $64 million of other long-term investments included in its Other Operations segment.

Management believes that White Mountains has the flexibility and capacity to obtain funds externally 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. As of March 31, 2018, the WTM Bank Facility was undrawn. On April 10, 2018, White Mountains commenced a modified Dutch tender offer (the “Tender Offer”) for up to 500,000 White Mountains common shares that will expire on May 7, 2018. White Mountains expects to terminate the WTM Bank Facility in conjunction with the completion of the Tender Offer.

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. These covenants can restrict White Mountains in several ways, including its ability to incur additional indebtedness. An uncured breach of these covenants could result in an event of default under the WTM Bank Facility, which would allow lenders to declare any amounts owed under the WTM Bank Facility to be immediately due and payable. In addition, a default under the WTM Bank Facility could occur if certain of White Mountains’s subsidiaries fail to pay principal and interest on a credit facility, mortgage or similar debt agreement (collectively, “covered debt”), or fail to otherwise comply with obligations in such covered debt agreements where such a default gives the holder of the covered debt the right to accelerate at least $75 million of principal amount of covered debt.

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.

On May 12, 2017, MediaAlpha entered into a secured credit facility (the “MediaAlpha Bank Facility”) with Western Alliance Bank, which had a total commitment of $20 million and a maturity date of May 12, 2020. On October 5, 2017, MediaAlpha refinanced the MediaAlpha Bank Facility in order to fund the acquisition of certain assets associated with the Health, Life and Medicare insurance business of Healthplans.com. The total commitment of the MediaAlpha Bank Facility was increased to $28 million and the maturity date was extended to October 6, 2020. The MediaAlpha Bank Facility consists of an $18 million term loan facility, which has an outstanding balance of $17 million as of March 31, 2018, and a revolving loan facility for $10 million, which has an outstanding balance of $5 million as of March 31, 2018.

Covenant Compliance

As of March 31, 2018, White Mountains was in compliance with all of the covenants under all of its debt instruments.

Share Repurchases

White Mountains’s board of directors has authorized the Company to repurchase its common shares from time to time, subject to market conditions. The repurchase authorizations do not have a stated expiration date. As of March 31, 2018, White Mountains may repurchase an additional 643,130 shares under these board authorizations. In addition, from time to time White Mountains has also repurchased its common shares through tender offers that were separately approved by its board of directors. The Tender Offer that commenced on April 10, 2018 does not impact the remaining number of shares authorized for repurchase.

The following table presents common shares repurchased by the Company through the first 4 months of 2018 and 2017, as well as the average price per share as a percent of adjusted book value per share.

Cash Flows

Detailed information concerning White Mountains’s cash flows during the three months ended March 31, 2018 and 2017 follows:

Cash flows from continuing operations for the three months ended March 31, 2018 and March 31, 2017

Net cash used for continuing operations was $45 million in the first three months of 2018 and $55 million in the first three months of 2017. Cash used for continuing operations decreased in the first three months of 2018 compared to the first three months of 2017, primarily due to the $21 million employee retirement payment paid in the first quarter of 2017 relative to 2018, which was partially offset by increased long-term incentive payments in 2018. White Mountains made long-term incentive payments totaling $28 million and $21 million during the first three months of 2018 and 2017. White Mountains does not believe these trends will have a meaningful impact on its future liquidity or its ability to meet its future cash requirements.

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.

Invested Assets

As of March 31, 2018, approximately 92% 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 investments, primarily investments in U.S. Treasuries, short-term investments, which include U.S. Treasury Bills and common equity securities. Investments valued using Level 2 inputs include fixed maturity investments, which have been disaggregated into classes, including debt securities issued by corporations, mortgage and asset-backed securities, municipal obligations, and foreign government, agency and provincial obligations. Investments valued using Level 2 inputs also include certain passive exchange traded funds (“ETFs”) that track U.S. stock indices such as the S&P 500 but are traded on foreign exchanges, which management values using the fund manager’s published NAV to account for the difference in market close times. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Investments valued using Level 3 fair value estimates are based upon unobservable inputs and include investments in certain fixed maturity investments, equity securities and other long-term investments where quoted market prices are unavailable or are not considered reasonable. Transfers between levels are based on investments held 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 White Mountains uses have indicated that they will only provide prices where observable inputs are available. In circumstances where quoted market prices are unavailable or are not considered reasonable, White Mountains estimates the fair value using industry standard pricing methodologies and observable inputs such as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids, offers, credit ratings, 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’s process to assess the reasonableness of the market prices obtained from the outside pricing sources covers substantially all of its fixed maturity investments and includes, but is not limited to, the evaluation of pricing methodologies and a review of the pricing services’ quality control procedures on at least an annual basis, a comparison of its invested asset prices obtained from alternate independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices and a review of the underlying assumptions utilized by the pricing services for select 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 $1.0 million from the expected price based on these assessment 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 does not appear to support the market price provided by the pricing services, White Mountains challenges the vendor provided 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 valuation process described above is generally applicable to all of White Mountains’s fixed maturity investments. For more detail on the techniques and inputs specific to asset classes within White Mountains’s fixed maturity investments. See Note 3 — “Investment Securities.”

Level 3 valuations are generated from techniques that use assumptions not observable in the market. These unobservable assumptions reflect White Mountains’s assumptions that market participants would use in valuing the investment. Generally, certain securities may start out as Level 3 when they are originally issued but as observable inputs become available in the 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 periodic and audited annual financial statements of hedge funds and private equity funds and discussing each fund’s pricing with the fund manager throughout the year. 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. The fair value of White Mountains’s investments in hedge funds and private equity funds has generally been determined using the fund manager’s NAV.

NON-GAAP FINANCIAL MEASURES

This report includes three non-GAAP financial measures that have been reconciled with their most comparable GAAP financial measures.

Adjusted book value per share is a non-GAAP financial measure which is derived by adjusting (i) the GAAP book value per share numerator and (ii) the common shares outstanding denominator, as described below. Beginning in 2017, the GAAP book value per share numerator has been adjusted (i) to include a discount for the time value of money arising from the expected timing of cash payments of principal and interest on the BAM surplus notes and (ii) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. Under GAAP, White Mountains is required to carry the BAM surplus notes, including accrued interest, at nominal value with no consideration for time value of money. Based on a debt service model that forecasts operating results for BAM through maturity of the surplus notes, the present value of the BAM surplus notes, including accrued interest, was estimated to be $159 million and $162 million less than the nominal GAAP carrying values as of March 31, 2018 and December 31, 2017, respectively. The value of HG Global’s unearned premium reserve, net of deferred acquisition costs, was $84 million and $82 million as of March 31, 2018 and December 31, 2017, respectively. White Mountains believes these adjustments are useful to management and investors in analyzing the intrinsic value of HG Global, including the value of the surplus notes and the value of the in-force business at HG Re, HG Global’s reinsurance subsidiary. The denominator used in the calculation of adjusted book value per share equals the number of common shares outstanding 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 GAAP book value per share to adjusted book value per share is included on page 39.

Adjusted EBITDA is defined as net income (loss) excluding interest expense on debt, income tax benefit (expense), depreciation and amortization, and non-cash equity-based compensation expense. White Mountains believes that this non-GAAP financial measure is useful to management and investors in analyzing MediaAlpha’s economic performance without the effects of interest rates, levels of debt, effective tax rates, depreciation and amortization primarily resulting from purchase accounting, or non-cash equity-based compensation. In addition, White Mountains believes that investors use adjusted EBITDA as a supplemental measurement to evaluate the overall operating performance of companies within the same industry. The reconciliation of MediaAlpha’s GAAP net income to adjusted EBITDA is included on page 46.

Total capital at White Mountains is comprised of White Mountains’s common shareholders’ equity, debt and non-controlling interests other than non-controlling interests attributable to mutuals and reciprocals. Total adjusted capital is a non-GAAP financial measure, which is derived by adjusting total capital (i) to include a discount for the time value of money arising from the expected timing of cash payments of principal and interest on the BAM Surplus Notes and (ii) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. The reconciliation of total capital to total adjusted capital is included on page 52.
