Note 1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

White Mountains Insurance Group, Ltd. (the “Company” or the “Registrant”) is an exempted Bermuda limited liability company whose principal businesses are conducted through its 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 23 South Main Street, Suite 3B, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11. The Company’s website is www.whitemountains.com. The information contained on White Mountains’s website is not incorporated by reference into, and is not a part of, this report.

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 the Company, its subsidiaries (collectively with the Company, “White Mountains”) and other entities required to be consolidated under GAAP. Intercompany transactions have been eliminated in consolidation. Certain amounts in the prior period financial statements have been reclassified to conform to the current presentation.

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.

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 ~~2021~~2022 Annual Report on Form 10-K.

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. As of September 30, ~~2022,~~2023, White ~~Mountains’s~~Mountains conducted its operations through three reportable ~~segments were~~segments: (1) HG Global/BAM, ~~Ark~~(2) Ark/WM Outrigger, and (3) Kudu, with our remaining operating businesses, holding companies and other assets included in Other Operations. White Mountains has made its segment determination based on consideration of the following criteria: (i) the nature of the business activities of each of the Company’s subsidiaries and affiliates; (ii) the manner in which the Company’s subsidiaries and affiliates are organized; (iii) the existence of primary managers responsible for specific subsidiaries and affiliates; and (iv) the organization of information provided to the Company’s chief operating decision makers and its Board of Directors. See Note 14 — “Segment Information.”

The HG Global/BAM segment consists of HG Global Ltd. and its wholly-owned subsidiaries ~~(“HG~~(collectively, “HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”) (collectively with HG Global, “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 purpose projects, 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 reinsurance 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, funded the initial capitalization of BAM through the purchase of $503.0 million of surplus notes issued by BAM (the “BAM Surplus Notes”). As of September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, 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 variable interest entity (“VIE”) for which White Mountains is the primary beneficiary. BAM’s results are all attributed to ~~non-controlling~~noncontrolling interests.

The ~~Ark~~Ark/WM Outrigger segment consists of Ark Insurance Holdings Limited and its subsidiaries (collectively, “Ark”) and Outrigger Re Ltd. Segregated Account 2023-1 (“WM Outrigger Re”) (collectively with Ark, “Ark/WM Outrigger”).

White Mountains acquired a controlling ownership interest in Ark on January 1, 2021 (the “Ark Transaction”). ~~See~~ ~~Note 2 — “Significant Transactions.~~” As of September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, White Mountains owned 72.0% of Ark on a basic shares outstanding basis (63.0% after taking account of management’s equity incentives). The remaining shares are owned by current and former employees. In the future, management rollover shareholders could earn additional shares in Ark if and to the extent that White Mountains achieves certain multiple of invested capital return thresholds. If fully earned, these additional shares would represent 12.5% of the shares outstanding at closing. The liability related to these additional shares is recorded as contingent consideration. For the years of account prior to the Ark Transaction, a significant proportion of the Syndicates’ underwriting capital was provided by third-party insurance and reinsurance groups (“TPC Providers”) using whole account reinsurance contracts with Ark’s corporate member. For the years of account subsequent to the Ark Transaction, Ark is no longer using TPC Providers to provide underwriting capital for the Syndicates. Captions within results of operations and other comprehensive income for the three and nine months ended September 30, 2022 are shown net of amounts relating to the TPC ~~Providers~~Providers’ share of the Syndicates’ results, including investment results. During the fourth quarter of 2022, Ark sponsored the formation of Outrigger Re Ltd., a Bermuda company registered as a special purpose insurer and segregated accounts company, to provide collateralized reinsurance protection on Ark’s Bermuda global property catastrophe excess of loss portfolio written in calendar year 2023.

Note 2. Significant Transactions

NSM

On August 1, 2022, the NSM Transaction closed. White Mountains received $1.4 billion in net cash proceeds at closing and recognized a net transaction gain of $875.7 million, which was comprised of $886.8 million of net gain from sale of discontinued operations and $2.9 million of comprehensive income related to the recognition of foreign currency translation gains (losses) from the sale, partially offset by $14.0 million of compensation and other costs related to the transaction recorded in Other Operations.

The proceeds from the issuance of the preference shares were deposited into collateral trust accounts to fund any potential obligations under the reinsurance agreements with GAIL. Outrigger Re Ltd.’s obligations under the reinsurance agreements with GAIL are subject to an aggregate limit equal to the assets in the collateral trusts at any point in time. The terms of the reinsurance agreements are renewable upon the mutual agreement of Ark and the applicable preference shareholder.

White Mountains purchased 100% of the preference shares issued by its segregated account, WM Outrigger Re, for $205.0 million. White Mountains consolidates WM Outrigger Re’s results in its financial statements. WM Outrigger Re’s quota share reinsurance agreement with GAIL eliminates in White Mountains’s consolidated financial statements.

Kudu

On May 26, 2022, Kudu raised $114.5 million of equity capital (the “Kudu Transaction”) from Massachusetts Mutual Life Insurance Company (“Mass Mutual”), White Mountains and Kudu management. Mass Mutual, White Mountains and Kudu management contributed $64.1 million, $50.0 million and $0.4 million ~~and in each case,~~ at a pre-money valuation of 1.3x book value, or $114.0 million above the December 31, 2021 equity value of Kudu’s go-forward portfolio of revenue and earnings participation ~~contracts. As of September 30, 2022, Kudu’s~~contracts (“Participation Contracts”). The go-forward portfolio of ~~participation contracts excludes $41.1~~Kudu’s Participation Contracts excluded $54.3 million of enterprise value as of December 31, 2021 relating to two portfolio companies that had announced sale transactions prior to the capital raise. As a result of the Kudu Transaction, White Mountains’s basic ownership of Kudu decreased from 99.1% to 89.3%.

~~Ark~~

On October 1, 2020, White Mountains entered into a subscription and purchase agreement (the “Ark SPA”) with Ark and certain selling shareholders (collectively with Ark, the “Ark Sellers”). Under the terms of the Ark SPA, White Mountains agreed to contribute $605.4 million of equity capital to Ark, at a pre-money valuation of $300.0 million, and to purchase $40.9 million of shares from the Ark Sellers. White Mountains also agreed to contribute up to an additional $200.0 million of equity capital to Ark in 2021. In accordance with the Ark SPA, in the fourth quarter of 2020, White Mountains pre-funded/placed in escrow a total of $646.3 million in preparation for closing the Ark Transaction, including $280.0 million funded directly to Lloyd’s on behalf of Ark under the terms of a credit facility agreement and $366.3 million placed in escrow.

On January 1, 2021, White Mountains completed the Ark Transaction in accordance with the terms of the Ark SPA. As of September 30, 2022, White Mountains owned 72.0% of Ark on a basic shares outstanding basis (63.0%) after taking account of management’s equity incentives). The remaining shares are owned by current and former employees. In the future, management rollover shareholders could earn additional shares in Ark if and to the extent that White Mountains achieves certain multiple of invested capital return thresholds. If fully earned, these additional shares would represent 12.5% of the shares outstanding at closing.

White Mountains recognized total assets acquired related to the Ark Transaction of $2.5 billion, including goodwill and other intangible assets of $292.5 million, and total liabilities of $1.7 billion, including contingent consideration of $22.5 million and non-controlling interest of $220.2 million. Ark incurred transaction costs of $25.3 million in the first quarter of 2021.

~~In the third quarter of 2021, Ark issued $163.3 million of floating rate unsecured subordinated notes (the “Ark 2021 Subordinated Notes”) in three separate transactions. See~~ ~~Note 7 — “Debt.”~~ In connection with the issuance of the Ark 2021 Subordinated Notes, White Mountains and Ark terminated White Mountains’s commitment to provide up to $200.0 million of additional equity capital to Ark in 2021.

~~The following presents additional details of the assets acquired and liabilities assumed as of the January 1, 2021 acquisition date:~~

Millions As of January 1, 2021
Investments $ 594.3
Cash 52.0 (1)
Reinsurance recoverables 433.4
Insurance premiums receivable 236.7

Other assets 88.9
Loss and loss adjustment expense reserves (696.0)
Unearned insurance premiums (326.1)
Debt (46.4)
Ceded reinsurance payable (528.3)
Other liabilities (25.9)
Net tangible assets acquired 24.5
Goodwill 116.8
Other intangible assets - syndicate underwriting capacity 175.7
Deferred tax liability on other intangible assets (33.4)
Net assets acquired $ 283.6

~~(1)~~ ~~Cash excludes the White Mountains cash contribution of $605.4 as part of the Ark transaction.~~

The values of net tangible assets acquired and the resulting goodwill, other intangible assets and contingent consideration were recorded at fair value using Level 3 inputs. The majority of the tangible assets acquired and liabilities assumed were recorded at their carrying values, as their carrying values approximated their fair values due to their short-term nature. The fair values of goodwill, other intangible assets and the contingent consideration liability were internally estimated primarily based on the income approach. The income approach estimates fair value based on the present value of the cash flows that the assets are expected to generate in the future. White Mountains developed internal estimates for the expected future cash flows and discount rates used in the present value calculations.

The value of in-force business acquired represents the estimated profits relating to the unexpired contracts, net of related prepaid reinsurance, at the acquisition date through the expiration date of the contracts. For the three and nine months ended September 30, 2022, Ark recognized $0.7 million and $6.8 million of amortization expense on the value of in-force business acquired. For the three and nine months ended September 30, 2021, Ark recognized $11.0 million and $54.9 million of amortization expense on the value of in-force business acquired. The value of the syndicate underwriting capacity intangible asset was estimated using net cash flows attributable to Ark’s rights to write business in the Lloyd’s market. The value of the in-force business acquired and the syndicate underwriting capacity were estimated using a discounted cash flow method. Significant inputs to the valuation models include estimates of growth in premium revenues, investment returns, claim costs, expenses and discount rates based on a weighted average cost of capital.

In evaluating the fair value of Ark’s loss and loss adjustment expense reserves (“LAE”), White Mountains determined that the risk-free rate of interest was approximately equal to the risk factor reflecting the uncertainty within the reserves and that no adjustment was necessary.

As of September 30, 2022 and December 31, 2021, Ark recognized total contingent consideration liabilities of $32.9 million and $28.0 million. Any future adjustments to contingent consideration liabilities will be recognized through pre-tax income (loss). For the three and nine months ended September 30, 2022, Ark recognized pre-tax expense of $2.7 million and $4.9 million for the change in the fair value of its contingent consideration liabilities. For both the three and nine months ended September 30, 2021, Ark recognized pre-tax expense of $1.5 million for the change in the fair value of its contingent consideration liabilities.

~~MediaAlpha~~

On October 30, 2020, MediaAlpha completed an initial public offering (the “MediaAlpha IPO”). In the offering, White Mountains sold 3.6 million shares at $19.00 per share ($17.67 per share net of underwriting fees) and received total proceeds of $63.8 million. White Mountains also received $55.0 million of net proceeds related to a dividend recapitalization at MediaAlpha.

On March 23, 2021, MediaAlpha completed a secondary offering of 8.05 million shares. In the secondary offering, White Mountains sold 3.6 million shares at $46.00 per share ($44.62 per share net of underwriting fees) for net proceeds of $160.3 million.

As of September 30, 2022, White Mountains owned 16.9 million shares, representing a 27.4% basic ownership interest (25.0% fully-diluted/fully-converted basis). At this current level of ownership, each $1.00 per share increase or decrease in the share price of MediaAlpha will result in an approximate $6.60 per share increase or decrease in White Mountains’s book value per share. At the September 30, 2022 closing price of $8.75 per share, the fair value of White Mountains’s investment in MediaAlpha was $148.2 million. See ~~Note 16 — “Equity-Method Eligible Investments.”~~

~~PassportCard/DavidShield~~

On January 24, 2018, White Mountains acquired a 50.0% ownership interest in DavidShield, its joint venture partner in PassportCard. DavidShield is an MGA 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 reorganized its equity stake in PassportCard so that White Mountains and its partner in DavidShield would each own 50.0% 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 50.0% interest in DavidShield was $41.8 million, or $28.3 million net of the financing provided for the restructuring.

On May 7, 2020, White Mountains made an additional $15.0 million investment in PassportCard/DavidShield to support operations through the ongoing COVID-19 pandemic. The transaction increased White Mountains’s ownership interest from 50.0% to 53.8%, but had no impact on the governance structure of the companies, including White Mountains’s board representation or other investor rights. The governance structures for both PassportCard and DavidShield were designed to give White Mountains and its co-investor equal power to make the decisions that most significantly impact the operations of PassportCard and DavidShield. Because White Mountains does not have the unilateral power to direct the operations of PassportCard or DavidShield, White Mountains does not hold a controlling financial interest in either PassportCard or DavidShield and does not consolidate either entity. White Mountains’s ownership interest gives White Mountains the opportunity to exert significant influence over the significant financial and operating activities of PassportCard and DavidShield. Accordingly, PassportCard and DavidShield meet the criteria to be accounted for under the equity method. White Mountains has taken the fair value option for its investment in PassportCard and DavidShield. Changes in the fair value of PassportCard and DavidShield are recorded in realized and unrealized investment gains. White Mountains’s maximum exposure to loss on its equity investment in PassportCard/DavidShield and the non-interest-bearing loan to its partner is limited to the total carrying value of $143.0 million.

Note 3. Investment Securities

White Mountains’s portfolio of investment securities held for general investment purposes consists of fixed maturity investments, short-term investments, common equity securities, its investment in MediaAlpha and other long-term investments, which are 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 fair value, which approximated amortized cost, as of September 30, ~~2022~~2023 and December 31, ~~2021.~~2022.

Other long-term investments consist primarily of unconsolidated entities, ~~including~~ Kudu’s Participation Contracts, private equity funds and hedge funds, a bank loan fund, Lloyd’s trust deposits, insurance-linked securities (“ILS”) funds and private debt ~~investments.~~instruments.

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, dividend income from common equity securities, distributions from its investment in MediaAlpha and distributions from other long-term investments.

The following table presents pre-tax net investment income for the three and nine months ended September 30, ~~2022~~2023 and ~~2021:~~2022:

Fair Value Measurements

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). See Note 17 — “Fair Value of Financial Instruments.”

As of September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, White Mountains used quoted market prices or other observable inputs to determine fair value for approximately ~~69%~~68% and ~~68%~~72% of the investment portfolio.

Fair Value Measurements by Level

The following tables present White Mountains’s fair value measurements for investments as of September 30, ~~2022~~2023 and December 31, ~~2021~~2022 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, 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 by industry sector because investors often reference commonly used benchmarks and their subsectors to monitor risk and performance. Accordingly, White Mountains has further disaggregated this asset class 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.

Note 4. Goodwill and Other Intangible Assets

White Mountains accounts for ~~purchases of businesses~~business combinations using the acquisition method. Under the acquisition method, White Mountains recognizes and measures the assets acquired, liabilities assumed and any ~~non-controlling~~noncontrolling interest in the acquired entities at their acquisition date fair values. Goodwill represents the excess of the amount paid to acquire businesses over the fair value of identifiable net assets at the date of acquisition. The estimated acquisition date fair values, generally consisting of intangible assets and liabilities for contingent consideration, may be recorded at provisional amounts in circumstances where the information necessary to complete the acquisition accounting is not available at the reporting date. Any such provisional amounts are finalized as measurement period adjustments within one year of the acquisition date.

The following table presents the economic lives, acquisition date fair values, accumulated amortization and net carrying values for other intangible assets and goodwill ~~by reportable segment~~ as of September 30, ~~2022~~2023 and December 31, ~~2021:~~2022:

Intangible Assets Valuation Methods

The goodwill recognized for the entities shown above is attributed to expected future cash flows. The acquisition date fair values of other intangible assets with finite lives are estimated using income approach techniques, which use future expected cash flows to develop a discounted present value amount.

The multi-period-excess-earnings method estimates fair value using the present value of the incremental after-tax cash flows attributable solely to the other intangible asset over its remaining life. This approach was used to estimate the fair value of other intangible assets associated with the underwriting capacity ~~trade names,~~and customer ~~relationships and contracts and information technology.~~relationships.

The relief-from-royalty method was used to estimate fair value for other intangible assets that relate to rights that could be obtained via a license from a third-party owner. Under this method, the fair value is estimated using the present value of license fees avoided by owning rather than leasing the asset. This technique was used to estimate the fair value of ~~domain~~trade names ~~certain trademarks~~ and ~~brand names.~~

other intangible assets.

The with-or-without method estimates the fair value of other intangible assets that provide an incremental benefit. Under this method, the fair value of the other intangible asset is calculated by comparing the value of the entity with and without the other intangible asset. This approach was used to estimate the fair value of favorable lease terms.

On at least an annual basis beginning no later than the interim period included in the one-year anniversary of an acquisition, White Mountains evaluates goodwill and other intangible assets for potential impairment. Between annual evaluations, White Mountains considers changes in circumstances or events subsequent to the most recent evaluation that may indicate ~~that~~ an impairment may exist and, if necessary will perform an interim review for potential impairment.

~~The following table presents a summary of~~During the ~~acquisition date fair values of~~three and nine months ended September 30, 2023 and 2022, White Mountains did not recognize any impairments to goodwill and other intangible ~~assets for acquisitions completed from January 1, 2021 through September 30, 2022:~~

For the three and nine months ended September 30, 2023, the Ark/WM Outrigger segment recognized $0.6 million of net favorable prior year loss reserve development and $19.0 million of net unfavorable prior year loss reserve development. The net unfavorable prior year loss reserve development for the nine months ended September 30, 2023 was driven primarily by Winter Storm Elliot and three large claims in the property and marine & energy lines of business. For the three and nine months ended September 30, 2022, ~~Ark~~the Ark/WM Outrigger segment recognized $9.2 million and $35.6 million of net favorable prior year loss reserve ~~development. Ark’s net favorable prior year loss reserve~~ development, ~~in 2022 was~~ driven primarily by good claims experience across most classes including the property and ~~accident & health and~~ specialty ~~reserving~~ lines of business, predominantly from business underwritten in London. For the three and nine months ended September 30, 2021, Ark recognized $12.7 million and $21.2 million of net favorable prior year loss reserve development. Ark’s net favorable prior year loss reserve development in 2021 was driven primarily by the property and accident & health reserving line of business.

~~TPC Providers’ Participation~~

Impact of Third-Party Capital

~~An RITC~~A reinsurance to close (“RITC”) agreement is generally put in place after the third year of operations for a year of account such that the outstanding loss and LAE reserves, including future development thereon, are reinsured into the next year of account. As a result, and in combination with the changing participation provided by TPC Providers, Ark’s participation on outstanding loss and LAE reserves reinsured into the next year of account may change, perhaps significantly. During the first quarter of 2023, an RITC agreement was executed such that the outstanding loss and LAE reserves for claims arising out of the 2020 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates was 42.8%, were reinsured into the 2021 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates was 0.0%. During the first quarter of 2022, an RITC agreement was executed such that the outstanding loss and LAE reserves for claims arising out of the 2019 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates was 58.3%, were reinsured into the 2020 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates iswas 42.8%. During the first quarter of 2021, an RITC was executed such that the outstanding loss and LAE reserves for claims arising out of the 2018 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates was 57.6%, were reinsured into the 2019 year of account, for which the TPC Providers’ participation in the total net results of the Syndicates was 58.3%.

Municipal Bond Guarantee Insurance

HG Re and BAM do not have any outstanding loss and LAE reserves related to BAM’s municipal bond guarantee insurance business.

Note 6. Third-Party Reinsurance

P&C Insurance and Reinsurance

In the normal course of business, Ark may seek to limit losses that may arise from catastrophes or other events by reinsuring certain risks with third-party reinsurers. Ark remains liable for risks reinsured in the event that the reinsurer does not honor its obligations under reinsurance contracts.

The following table summarizes the effects of reinsurance on written and earned premiums and on losses and LAE for ~~Ark~~the Ark/WM Outrigger segment for the three and nine months ended September 30, ~~2022~~2023 and ~~2021:~~2022:

As reinsurance contracts do not relieve Ark of its obligation to its policyholders, Ark seeks to reduce the credit risk associated with reinsurance balances by avoiding over-reliance on specific reinsurers through the application of concentration limits and thresholds. Ark is selective with its reinsurers, placing reinsurance with only those reinsurers having a strong financial condition. Ark monitors the financial strength of its reinsurers on an ongoing basis.

As of September 30, 2022, Ark’s reinsurance recoverables of $550.9 million included $168.0 million attributable to TPC Providers, which are collateralized. As of September 30, 2021, Ark’s reinsurance recoverables of $465.6 million included $299.9 million related to TPC Providers, which are collateralized.

HG Global Senior Notes

On April 29, 2022, HG Global received the proceeds from the issuance of its $150.0 million face value floating rate secured senior notes (the “HG Global Senior Notes”). The HG Global Senior Notes, which mature in April 2032, accrue interest at a floating rate equal to the three-month Secured Overnight Financing Rate (“SOFR”) plus 6.3% per annum. Subsequent to the five-year anniversary of the funding date, absent the occurrence of an early amortization trigger event, HG Global will be required to make payments of principal on a quarterly basis totaling $15.0 million annually. Upon the occurrence of an early amortization trigger event, HG Global is required to use all available cash flow to repay the notes. Early amortization trigger events include scenarios in which HG Re is effectively in ~~run off.~~runoff. HG Global has the option to redeem, in whole or in part, the HG Global Senior Notes after the five-year anniversary of the funding date at the outstanding principal ~~amounts~~amount plus accrued interest.

On June 16, 2022, HG entered into an interest rate cap agreement, effective on July 25, 2022, to limit its exposure to the risk of interest rate increases on the HG Global Senior Notes. The notional amount of the interest rate cap is $150.0 million and the termination date is July 25, 2025. See Note 9— “Derivatives.”

The HG Global Senior Notes require HG Global to maintain an interest reserve account of eight times the interest accrued for the most recent quarterly interest ~~period,~~period. While the interest rate cap is in force, the interest reserve account is subject to a maximum required balance of $29.2 million. As of September 30, 2023, the fair value of the interest reserve account, which is included in short-term ~~investments. As of September 30, 2022, the interest reserve account is $26.4~~investments, was $29.9 million.

The HG Global Senior Notes are secured by the capital stock and other equity interests of HG Global’s subsidiaries, the interest reserve account, and all cash and non-cash proceeds from ~~the foregoing~~such collateral. The HG Global Senior Notes contain various affirmative and negative covenants that White Mountains considers to be customary for such borrowings.

If the ~~payments~~payment of principal and interest under the HG Global Senior Notes ~~become~~becomes subject to tax withholding on behalf of a relevant governmental authority for certain indemnified taxes, the HG Global Senior Notes require the payment of additional amounts such that the amount received by the noteholders is the same as would have been received absent the tax withholding being imposed. The HG Global Senior Notes require the payment of additional interest of 1.0% per annum if the HG Global Senior Notes receive a non-investment grade rating or are no longer rated. As of September 30, 2023, the HG Global Senior Notes had an investment grade rating.

As of September 30, ~~2022,~~2023, the HG Global Senior Notes had an outstanding ~~principal~~ balance of $150.0 million.

On July 13, 2021, Ark issued €39.1 million ($46.3 million based upon the foreign exchange spot rate as of the date of the transaction) face value floating rate unsecured subordinated notes (“Ark 2021 Subordinated Notes Tranche 1”). The Ark 2021 Subordinated Notes Tranche 1, which mature in July 2041, accrue interest at a floating rate equal to the three-month ~~EURIBOR~~Euro Interbank Offered Rate (“EURIBOR”) plus 5.75% per annum. On August 11, 2021, Ark issued $47.0 million face value floating rate unsecured subordinated notes (“Ark 2021 Subordinated Notes Tranche 2”). The Ark 2021 Subordinated Notes Tranche 2, which mature in August 2041, accrue interest at a floating rate equal to the three-month U.S. LIBOR plus 5.75% per annum. On September 8, 2021, Ark issued $70.0 million face value floating rate unsecured subordinated notes (“Ark 2021 Subordinated Notes Tranche 3”). The Ark 2021 Subordinated Notes Tranche 3, which mature in September 2041, accrue interest at a floating rate equal to the three-month U.S. LIBOR plus 6.1% per annum.

Ark has the option to redeem, in whole or in part, the Ark 2021 Subordinated Notes ahead of contractual maturity at the outstanding principal amounts plus accrued interest at the ten-year anniversary or any subsequent interest payment date.

All payments of principal and interest under the Ark 2021 Subordinated Notes are conditional upon GAIL’s solvency and compliance with the enhanced capital requirements of the Bermuda Monetary Authority (“BMA”). The deferral of payments of principal and interest under these conditions does not constitute a default by Ark and does not give the noteholders any rights to accelerate repayment of the Ark 2021 Subordinated Notes or take any enforcement action under the Ark 2021 Subordinated Notes.

If the payments of principal and interest under the Ark 2021 Subordinated Notes become subject to tax withholding on behalf of Bermuda or any political subdivision there, the Ark 2021 Subordinated Notes require the payment of additional amounts such that the amount received by the noteholders is the same as would have been received absent the tax withholding being imposed. The Ark 2021 Subordinated Notes Tranche 3 require the payment of additional interest of 1.0% per annum upon the occurrence of a premium load event until such event is remedied. Premium load events include the failure to meet payment obligations of the Ark 2021 Subordinated Notes Tranche 3 when due, failure of GAIL to maintain an investment grade credit rating, failure to maintain 120% of GAIL’s Bermuda solvency capital requirement, failure of GAIL to maintain a debt to capital ratio below 40%, late filing of GAIL’s or Ark’s financial information, and making a restricted payment or distribution on GAIL’s common stock or other securities that rank junior or pari passu with the Ark 2021 Subordinated Notes Tranche 3 when a different premium load event exists or will be caused by the restricted payment. As of September 30, 2023, there were no premium load events.

As of September 30, ~~2022,~~2023, the Ark 2021 Subordinated Notes Tranche 1 had an outstanding ~~principal~~ balance of €39.1 million ($~~37.6~~41.9 million based upon the foreign exchange spot rate as of September 30, ~~2022)~~2023), the Ark 2021 Subordinated Notes Tranche 2 had an outstanding ~~principal~~ balance of $47.0 million, and the Ark 2021 Subordinated Notes Tranche 3 had an outstanding ~~principal~~ balance of $70.0 million.

The Ark Subordinated Notes contain various affirmative and negative covenants that White Mountains considers to be customary for such borrowings.

As of September 30, ~~2022,~~2023, White Mountains’s Other Operations had debt with an outstanding ~~principal~~ balance of ~~$36.4~~$30.1 million, which consisted of ~~five~~four secured credit facilities (collectively, “Other Operations debt”).

Compliance

At September 30, ~~2022,~~2023, White Mountains was in compliance, in all material respects, with all of the covenants under ~~all of~~ its debt instruments.

Note 8. Income Taxes

The Company and its Bermuda domiciled subsidiaries are not subject to ~~Bermuda~~ income tax under current Bermuda law. In the event there is a change in the current law such that taxes are imposed, the Bermuda Exempted Undertakings Tax Protection Act of 1966 states that the Company and its Bermuda domiciled subsidiaries would be exempt from such tax until March 31, 2035. The Company has subsidiaries and branches that operate in various other jurisdictions around the world and are subject to tax in the jurisdictions in which they operate. As of September 30, ~~2022,~~2023, the primary jurisdictions in which the Company’s subsidiaries and branches were subject to tax ~~were~~include Ireland, Israel, Luxembourg, the United Kingdom and the United States.

White Mountains’s income tax expense related to pre-tax income from continuing operations for the three months ended September 30, 2023 represented an effective tax rate of 34.6%. The effective tax rate was different from the U.S. statutory rate of 21.0%, driven primarily by an increase in the valuation allowance at BAM, as well as withholding taxes and state income taxes, partially offset by full year forecasted income in jurisdictions with lower tax rates than the United States.

White Mountains’s income tax expense related to pre-tax income from continuing operations for the nine months ended September 30, 2023 represented an effective tax rate of 8.2%. The effective tax rate was different from the U.S. statutory rate of 21.0%, driven primarily by full year forecasted income in jurisdictions with lower tax rates than the United States.

White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the three and nine months ended September 30, 2022 represented an effective tax rate of 23.9% and 9.4%. The effective tax rate for the nine months ended September 30, 2022 was different from the U.S. statutory rate of 21.0%, driven primarily by full year forecasted income in jurisdictions with lower tax rates than the United States, partially offset by ~~a full~~an increase in the valuation allowance on net deferred tax assets in certain U.S. operations ~~consisting of the WM Adams, Inc. consolidated tax group~~ within Other Operations, ~~and~~an increase in the valuation allowance at BAM, ~~and~~as well as state income taxes.

~~White Mountains’s income tax expense related to pre-tax loss from continuing operations for~~On April 1, 2023, the three and nine months ended September 30, 2021 represented an effective tax rate of (7.9)% and (17.1)%. The effective tax rate was different from the U.S. statutory rate of 21.0%, driven primarily by losses in jurisdictions with lower tax rates than the United States, a full valuation allowance on net deferred tax assets in certain U.S. operations, consisting of the WM Adams, Inc. consolidated tax group within Other Operations and BAM, and state income taxes. For the nine months ended September 30, 2021, the effective rate was also different from the U.S. statutory rate of 21.0% due to additional tax expense related to the revaluation of U.K. ~~deferred tax assets and liabilities.~~

~~On June 10, 2021, the U.K. enacted an increase in its~~ corporate tax rate increased from 19.0% to 25.0% for periods after April 1, 2023. On June 30, 2021, White Mountains increased its net U.K. deferred tax liability to reflect the higher tax rate on temporary differences projected to reverse after the new rate becomes effective..

On August 16, 2022, the U.S. enacted the Inflation Reduction Act (the “IRA”). White Mountains has evaluated the tax provisions of the IRA, the most significant of which relate to the corporate alternative minimum tax and the tax on share repurchases, and does not expect the legislation to have a material impact on ~~its~~the results of its operations.

In arriving at the effective tax rate for the three and nine months ended September 30, ~~2022~~2023 and ~~2021,~~2022, White Mountains forecasted all income and expense items including the change in net unrealized investment gains (losses) and net realized investment gains (losses) for the years ending December 31, ~~2022~~2023 and ~~2021.~~2022.

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 ~~2016.~~2017.

Note 9. Derivatives

HG Global Interest Rate Cap

HG paid initial premiums of $3.3 million for the interest rate cap. Under the terms of the interest rate cap agreement, if the current three-month SOFR rate at the measurement date exceeds 3.5%, HG will receive payments from the counterparty equal to the difference between the three-month SOFR rate on the determination date and 3.5%, multiplied by the notional amount of the cap based on the number of days in the ~~quarter and a year equal to 360 days.~~quarter. As of September 30, ~~2022,~~2023, the three-month SOFR rate was ~~3.6%~~5.4%.

HG accounts for the interest rate cap as a derivative at fair value, with changes in fair value recognized in current period earnings within interest expense. For the three and nine months ended September 30, 2023, White Mountains recognized a gain of $0.0 million and $0.7 million related to the change in fair value on the interest rate cap within interest expense. For the three and nine months ended September 30, 2022, White Mountains recognized a gain of $2.1 million and $0.6 million related to the change in fair value on the interest rate ~~cap within~~cap. For the three and nine months ended September 30, 2023, White Mountains received a payment of $0.6 million and $1.2 million related to the periodic settlement of the interest ~~expense.~~rate cap. As of September 30, 2023 and December 31, 2022, the estimated fair value of the interest rate cap recorded in other assets was ~~$3.9~~$4.8 million and $4.1 million. White Mountains classifies the interest rate cap as a Level 2 measurement.

Note 10. Municipal Bond Guarantee Insurance

HG Global was established to fund the startup of BAM, a mutual municipal bond insurer. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503.0 million of the BAM Surplus Notes.

Reinsurance Treaties

FLRT

BAM is a party to a first loss reinsurance treaty (“FLRT”) with HG Re under which HG Re provides first loss protection up to 15%-of-par outstanding on each municipal bond insured by BAM. For capital appreciation bonds, par is adjusted to the estimated equivalent par value for current interest paying bonds. In return, BAM cedes ~~up to~~approximately 60% of the risk premium charged for insuring the municipal bond, which is net of a ceding commission. The FLRT is a perpetual agreement with terms that can be renegotiated after a specified period of time. During 2021, BAM and HG Re agreed that the terms may be renegotiated at the end of 2024, and each subsequent five-year period thereafter.

Fidus Re

BAM is party to a collateralized financial guarantee excess of loss reinsurance agreement that serves to increase BAM’s claims paying resources and is provided by Fidus Re Ltd. (“Fidus Re”).

In 2018, Fidus Re was initially capitalized by the issuance of $100.0 million of insurance-linked securities (the “Fidus Re 2018 Agreement”)., which have an initial term of 12 years and are callable five years after the date of issuance. The proceeds from issuance were placed in a collateral trust supporting Fidus Re’s obligations to BAM. ~~The insurance-linked securities were issued by Fidus Re with an initial term of 12 years and are callable five years after the date of issuance.~~ Under the Fidus Re 2018 Agreement, Fidus Re reinsures 90% of aggregate losses exceeding $165.0 million on a portion of BAM’s financial guarantee portfolio (the “2018 Covered Portfolio”) up to a total reimbursement of $100.0 million. The Fidus Re 2018 Agreement does not provide coverage for losses in excess of $276.1 million. The 2018 Covered Portfolio consists of approximately ~~28%~~24% of BAM’s ~~portfolio~~gross par outstanding as of ~~financial guaranty policies issued through~~ September 30, ~~2022.~~2023.

In ~~the first quarter of~~ 2021, Fidus Re issued an additional $150.0 million of insurance-linked securities (the “Fidus Re 2021 Agreement”) ~~with~~, which have an initial term of 12 years and are callable five years after the date of issuance. The proceeds from issuance were placed in a collateral trust supporting Fidus Re’s obligations to BAM. Under the Fidus Re 2021 Agreement, Fidus Re reinsures 90% of aggregate losses exceeding $135.0 million on a portion of BAM’s financial guarantee portfolio (the “2021 Covered Portfolio”) up to a total reimbursement of $150.0 million. The Fidus Re 2021 Agreement does not provide coverage for losses in excess of $301.7 million. The 2021 Covered Portfolio consists of approximately ~~33%~~29% of BAM’s ~~portfolio~~gross par outstanding as of ~~financial guaranty policies issued through~~ September 30, ~~2022.~~2023.

In 2022, Fidus Re issued an additional $150.0 million of insurance linked securities (the “Fidus Re 2022 Agreement”), which have an initial term of 12 years and are callable seven years after the date of issuance. The proceeds from issuance were placed in a collateral trust supporting Fidus Re’s obligations to BAM. Under the Fidus Re 2022 Agreement, Fidus Re reinsures 90% of aggregate losses exceeding $110.0 million on a portion of BAM’s financial guarantee portfolio (the “2022 Covered Portfolio”) up to a total reimbursement of $150.0 million. The Fidus Re 2022 Agreement does not provide coverage for losses in excess of $276.7 million. The 2022 Covered Portfolio consists of approximately 30% of BAM’s gross par outstanding as of September 30, 2023.

The Fidus Re agreements are accounted for using deposit accounting and any related financing expenses are recorded in general and administrative expenses as they do not meet the risk transfer requirements necessary to be accounted for as reinsurance.

XOLT

In January 2020, BAM entered into an excess of loss reinsurance agreement (the “XOLT”) with HG Re. Under the XOLT, HG Re provides last dollar protection for exposures on municipal bonds insured by BAM in excess of the New York State Department of Financial Services (“NYDFS”) single issuer limits. As of September 30, ~~2022,~~2023, the XOLT is subject to an aggregate limit equal to the lesser of $125.0 million or the assets held in the supplemental collateral trust (the “Supplemental Trust”) at any point in time. The agreement is accounted for using deposit accounting and any related financing expenses are recorded in general and administrative expenses as the agreement does not meet the risk transfer requirements necessary to be accounted for as reinsurance.

Collateral Trusts

HG Re’s obligations under the FLRT are ~~limited to the assets in two collateral trusts: the Supplemental Trust and a Regulation 114 Trust (together, the “Collateral Trusts”). Losses required to be reimbursed under the FLRT are~~ subject to an aggregate limit equal to the assets ~~held~~ in two collateral trusts, the ~~Collateral Trusts~~Supplemental Trust and the Regulation 114 Trust (together, the “Collateral Trusts”), at any point in time.

On a monthly basis, BAM deposits cash equal to ceded premiums, net of ceding commissions, due to HG Re under the FLRT directly into the Regulation 114 Trust. The Regulation 114 Trust target balance is equal to ~~gross ceded~~HG Re’s unearned premiums and unpaid ~~ceded~~ loss and LAE reserves, if any. If, at the end of any quarter, the Regulation 114 Trust balance is below the target balance, funds will be withdrawn from the Supplemental Trust and deposited into the Regulation 114 Trust in an amount equal to the shortfall. If, at the end of any quarter, the Regulation 114 Trust balance is above 102% of the target balance, funds will be withdrawn from the Regulation 114 Trust and deposited into the Supplemental Trust. The Regulation 114 Trust balance as of September 30, ~~2022~~2023 and December 31, ~~2021~~2022 was ~~$259.4~~$311.2 million and ~~$250.2~~$288.6 million.

The Supplemental Trust target balance is $603.0 million, less the amount of cash and securities in the Regulation 114 Trust in excess of its target balance (the “Supplemental Trust Target Balance”). If, at the end of any quarter, the Supplemental Trust balance exceeds the Supplemental Trust Target Balance, such excess may be distributed to HG Re. The distribution will be made first as an assignment of accrued interest on the BAM Surplus Notes and second in cash and/or fixed income securities.

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 Supplemental Trust balance as of September 30, ~~2022~~2023 and December 31, ~~2021~~2022 was ~~$574.5~~$588.5 million and ~~$601.8~~$568.3 million.

As of September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, the Collateral Trusts held assets of ~~$833.9~~$899.7 million and ~~$852.0~~$856.9 million, which included ~~$457.7~~$526.5 million and ~~$481.7~~$503.3 million of cash and investments, ~~$364.6~~$340.0 million and ~~$364.6~~$340.0 million of BAM Surplus Notes and ~~$11.6~~$33.2 million and ~~$5.7~~$13.6 million of interest receivable on the BAM Surplus Notes.

BAM Surplus Notes

Through 2024, the interest rate on the BAM Surplus Notes is a variable rate equal to the one-year U.S. Treasury rate plus 300 basis points, set annually. During ~~2022,~~2023, the interest rate on the BAM Surplus Notes is ~~3.2%~~7.7%. Beginning in 2025, the interest rate will be fixed at the higher of the then current variable rate or 8.0%. Under its agreements with HG Global, BAM is required to seek regulatory approval to pay ~~interest~~principal and ~~principal~~interest on the BAM Surplus Notes only to the extent that its remaining qualified statutory capital and other capital resources continue to support its outstanding obligations, its business plan and its “AA/stable” rating from Standard & Poor’s. No payment of principal or interest on the BAM Surplus Notes may be made without the approval of the NYDFS.

In December ~~2021,~~2022, BAM made a ~~$33.8~~$36.0 million cash payment of principal and interest on the BAM Surplus Notes held by HG Global. Of this payment, ~~$23.6~~$24.6 million was a repayment of principal held in the Supplemental Trust, ~~$0.4~~$1.0 million was a payment of accrued interest held ~~inside~~in the Supplemental Trust and ~~$9.8~~$10.4 million was a payment of accrued interest held outside the Supplemental Trust.

During the three and nine months ended September 30, ~~2022~~2023 and ~~2021,~~2022, BAM made no repayments of the BAM Surplus Notes or accrued interest.

As of September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, the principal balance on the BAM Surplus Notes was ~~$364.6~~$340.0 million ~~and $364.6 million~~for both periods, and total interest receivable on the BAM Surplus Notes was ~~$166.4~~$177.6 million and ~~$157.6~~$157.9 million.

Note 11. 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 and nine months ended September 30, ~~2022~~2023 and ~~2021.~~2022. See Note 19 — “Held for Sale and Discontinued Operations.”

Note 12. Employee Share-Based Incentive Compensation Plans

White Mountains’s share-based incentive compensation plans are designed to incentivize key employees to maximize shareholder value over long periods of time. White Mountains believes that this is best pursued by utilizing a pay-for-performance program that closely aligns the financial interests of management with those of its shareholders while rewarding appropriate risk taking. White Mountains accomplishes this by emphasizing variable long-term compensation that is contingent on performance over a number of years rather than fixed entitlements. White Mountains expenses all of its share-based compensation. As a result, White Mountains’s calculation of its owners’ returns includes the expense of all outstanding share-based compensation awards.

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 and directors of White Mountains. As of September 30, ~~2022~~2023 and ~~2021,~~2022, White Mountains’s share-based incentive compensation ~~incentive~~ awards consist of performance shares and restricted shares.

Performance Shares

Performance shares are designed to reward employees for meeting company-wide performance targets. 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 service 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 paid. Performance shares earned under the WTM Incentive Plan are typically paid in cash but may be paid in common shares. Compensation expense is recognized for the vested portion of the awards over the related service periods. The level of payout ranges from zero to two times the number of shares initially granted, depending on White Mountains’s financial performance. Performance shares become payable at the conclusion of a performance cycle (typically 3three years) if pre-defined financial targets are met. The performance measures used for determining performance share payouts are growth in White Mountains’s adjusted book value per share and intrinsic value per share. Intrinsic value per share is generally calculated by adjusting adjusted book value per share for differences between the adjusted book value of certain assets and liabilities and White Mountains’s estimate of their underlying intrinsic values.

The following table presents the performance share activity for the three and nine months ended September 30, ~~2022~~2023 and ~~2021~~2022 for performance shares granted under the WTM Incentive Plan:

~~Note 13. Leases~~

White Mountains has entered into lease agreements, primarily for office space. These leases are classified as operating leases, with lease expense recognized on a straight-line basis over the term of the lease. Lease incentives, such as free rent or landlord reimbursements for leasehold improvements, are recognized at lease inception and amortized on a straight-line basis over the term of the lease. Lease expense and the amortization of leasehold improvements are recognized within general and administrative expenses. Lease payments related to options to extend or renew the lease term are excluded from the calculation of lease liabilities unless White Mountains is reasonably certain of exercising those options.

~~As of September 30, 2022 and December 31, 2021, the right of use (“ROU”) lease assets were $24.5 million and $28.1 million and lease liabilities were $26.5 million and $30.0 million.~~

Note ~~15.~~14. Segment Information

As of September 30, ~~2022,~~2023, White Mountains conducted its operations through ~~four~~three reportable segments: (1) HG Global/BAM, (2) ~~Ark,~~Ark/WM Outrigger, and (3) Kudu, with our remaining operating businesses, holding companies and ~~(4)~~other assets included in Other Operations. As a result of the NSM Transaction, the results of operations for NSM, previously reported as a segment, have been classified as discontinued operations in the statements of operations and comprehensive income through the closing of the transaction. Prior period amounts have been reclassified to conform to the current period’s presentation. See ~~Note 19 — “Held for Sale and Discontinued Operations.”~~

White Mountains has made its segment determination based on consideration of the following criteria: (i) the nature of the business activities of each of the Company’s subsidiaries and affiliates; (ii) the manner in which the Company’s subsidiaries and affiliates are organized; (iii) the existence of primary managers responsible for specific subsidiaries and affiliates; and (iv) the organization of information provided to the chief operating decision makers and the Board of Directors. Significant intercompany transactions among White Mountains’s segments have been eliminated herein.

During the fourth quarter of 2022, Ark sponsored the formation of Outrigger Re Ltd. to provide reinsurance protection on Ark’s Bermuda global property catastrophe excess of loss portfolio written in calendar year 2023. White Mountains consolidates its segregated account of Outrigger Re Ltd., WM Outrigger Re, in its financial statements. WM Outrigger Re’s quota share reinsurance agreement with GAIL eliminates in White Mountains’s consolidated financial statements. WM Outrigger Re exclusively provides reinsurance protection to Ark. As a result, WM Outrigger Re was aggregated with Ark within the Ark/WM Outrigger segment starting in 2023. See Note 2 — “Significant Transactions.”

As a result of the NSM Transaction, the results of operations for NSM, previously reported as a segment, have been classified as discontinued operations in the statements of operations and comprehensive income through the closing of the transaction. See Note 19 — “Held for Sale and Discontinued Operations.”

Prior period amounts have been reclassified to conform to the current period’s presentation.

BAM

BAM is owned by and operated for the benefit of its members, the municipalities that purchase BAM’s insurance for their debt issuances. However, the equity at risk funded by BAM’s members is not sufficient to fund its operations without the additional financial support provided by the BAM Surplus Notes and, accordingly, White Mountains has determined that BAM is a VIE.

Pursuant to the FLRT, BAM’s underwriting guidelines may only be amended with the consent of HG Re. In addition, HG Holdings Ltd, a subsidiary of HG Global, has the right to designate two directors for election to BAM’s Board of Directors. As a result, we have determined that White Mountains is the primary beneficiary and is required to consolidate BAM’s results in its financial statements. Since BAM is owned by its members, its equity and results of operations are included in noncontrolling interests.

HG Re’s obligations under the FLRT are subject to an aggregate limit equal to the assets in the Collateral Trusts at any point in time.

WM Outrigger Re

White Mountains has determined that Outrigger Re Ltd. and WM Outrigger Re are VIEs. White Mountains is not the primary beneficiary of Outrigger Re Ltd. or the other segregated accounts. White Mountains is the primary beneficiary of WM Outrigger Re, as it has both the power to direct the activities that most significantly impact WM Outrigger Re’s economic performance and the obligation to absorb losses, or the right to receive returns, that could potentially be significant to WM Outrigger Re. As a result, White Mountains consolidates WM Outrigger Re’s results in its financial statements. The assets of WM Outrigger Re can only be used to settle the liabilities of WM Outrigger Re, and there is no recourse to the Company for any creditors of WM Outrigger Re.

PassportCard/DavidShield

As of September 30, 2023, White Mountains’s ownership interest in PassportCard/DavidShield was 53.8%. White Mountains has determined that both PassportCard and DavidShield are VIEs but that White Mountains is not the primary beneficiary and therefore does not consolidate either PassportCard or DavidShield. The governance structures for both PassportCard and DavidShield were designed to give White Mountains and its co-investor equal power to make the decisions that most significantly impact operations. White Mountains does not have the unilateral power to direct the operations of PassportCard or DavidShield and does not hold a controlling financial interest. White Mountains’s ownership interest gives White Mountains the ability to exert significant influence over the significant financial and operating activities of PassportCard/DavidShield. Accordingly, White Mountains’s investment in PassportCard/DavidShield meets the criteria to be accounted for under the equity method. White Mountains has taken the fair value option for its investment in PassportCard/DavidShield. Changes in the fair value of PassportCard/DavidShield are recorded in net realized and unrealized investment gains (losses). As of September 30, 2023, White Mountains’s maximum exposure to loss on its equity investment in PassportCard/DavidShield and the non-interest-bearing loan to its partner is the total carrying value of $159.4 million.

Elementum

As of September 30, 2023, White Mountains’s ownership interest in Elementum was 26.6%. White Mountains has determined that Elementum is a VIE but that White Mountains is not the primary beneficiary and therefore does not consolidate Elementum. White Mountains’s ownership interest gives White Mountains the ability to exert significant influence over the significant financial and operating activities of Elementum. Accordingly, Elementum meets the criteria to be accounted for under the equity method. White Mountains has taken the fair value option for its investment in Elementum. Changes in the fair value of Elementum are recorded in net realized and unrealized investment gains (losses). As of September 30, 2023, White Mountains’s maximum exposure to loss on its limited partnership interest in Elementum is the carrying value of $35.0 million.

Limited Partnerships

White Mountains’s investments in limited partnerships are generally considered VIEs because the limited partnership interests do not have substantive kick-out rights or participating rights. White Mountains does not have the unilateral power to direct the operations of these limited partnerships, and therefore White Mountains is not the primary beneficiary and does not consolidate the limited partnerships. White Mountains has taken the fair value option for its investments in limited partnerships, which are generally measured at NAV as a practical expedient. As of September 30, 2023, White Mountains’s maximum exposure to loss on its investments in limited partnerships is the carrying value of $239.2 million.

Note 18. Commitments and Contingencies

Legal Contingencies

White Mountains, and the insurance industry in general, is routinely subject to claims related litigation and arbitration in the normal course of business, as well as litigation and arbitration that do not arise from, nor are directly related to, claims activity. White Mountains’s estimates of the costs of settling matters routinely encountered in claims activity are reflected in the reserves for unpaid loss and LAE. See Note 5 — “Losses and Loss Adjustment Expense Reserves.”

White Mountains considers the requirements of ASC 450 when evaluating its exposure to non-claims related litigation and arbitration. ASC 450 requires that accruals be established for litigation and arbitration if it is probable that a loss has been incurred and it can be reasonably estimated. ASC 450 also requires that litigation and arbitration be disclosed if it is probable that a loss has been incurred or if there is a reasonable possibility that a loss may have been incurred. White Mountains does not have any current non-claims related litigation that may have a material adverse effect on White Mountains’s financial condition, results of operations or cash flows.

Note 19. Held for Sale and Discontinued Operations

NSM

On August 1, 2022, White Mountains closed the NSM Transaction. See Note 2 — “Significant Transactions.” As a result of the NSM Transaction, the assets and liabilities of NSM Group have been presented in the balance sheet as held for sale for periods prior to the closing of the transaction, and the results of operations for NSM Group have been classified as discontinued operations in the statements of operations and comprehensive income through the closing of the transaction. Prior period amounts have been reclassified to conform to the current period’s presentation.

~~Sirius Group~~

On April 18, 2016, White Mountains completed the sale of Sirius International Insurance Group, Ltd. (“Sirius Group”) to CM International Pte. Ltd. and CM Bermuda Limited (collectively “CMI”). In connection with the sale, White Mountains indemnified Sirius Group against the loss of certain interest deductions claimed by Sirius Group related to periods prior to the sale of Sirius Group to CMI that had been disputed by the Swedish Tax Agency. In late October 2018, the Swedish Administrative Court ruled against Sirius Group on its appeal of the Swedish Tax Agency’s denial of these interest deductions. As a result, in 2018 White Mountains recorded a loss of $17.3 million within net gain (loss) on sale of discontinued operations reflecting the value of these interest deductions.

As of December 31, 2020, White Mountains’s liability related to the tax indemnification provided in connection with the sale of Sirius Group in 2016 was $18.7 million. In April 2021, the Swedish Tax Agency informed the Swedish Administrative Court of Appeal that Sirius Group should prevail in its appeal and that the interest deductions should not be disallowed. In June 2021, the Swedish Administrative Court of Appeal ruled in Sirius Group’s favor. For the nine months ended September 30, 2021, White Mountains recorded a gain of $17.6 million in discontinued operations to reverse the liability accrued as of December 31, 2020 and $1.1 million gain related to foreign currency translation.

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 and nine months ended September 30, ~~2022 and 2021:~~2022:

Note 20. Subsequent Events

Agreement to Acquire Bamboo

On October 19, 2023, White Mountains entered into an agreement and plan of merger (the “Bamboo Merger Agreement”) with Bamboo IDE8 Insurance Services, LLC (“Bamboo”) and John Chu, as the unitholders’ representative. Bamboo is a capital-light, tech- and data-enabled insurance distribution platform providing insurance offerings to the residential property market in California. Bamboo operates primarily through its full-service MGA business, where the company manages all aspects of the placement process on behalf of its fronting and reinsurance partners, including product development, marketing, underwriting, policy issuance and claims oversight, and earns commissions based on the volume and profitability of the insurance that it places.

Immediately following the merger, White Mountains will make a primary investment in Bamboo (together with the merger and the rollover transactions described below, the “Bamboo Transaction”). As a result of the Bamboo Transaction, White Mountains expects to acquire approximately 70% of the issued and outstanding equity interests of Bamboo for approximately $285 million in cash. The precise size of White Mountains’s ownership interest and equity investment will vary based on rollover elections by certain unitholders prior to closing.

The Bamboo Transaction is expected to close in the first quarter of 2024. Completion of the Bamboo Transaction is subject to receipt of certain regulatory approvals and other customary closing conditions. The Bamboo Transaction is not subject to a financing condition.

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” on page 76 for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

The following discussion also includes ~~nine~~five non-GAAP financial measures: (i) adjusted book value per share, (ii) ~~Ark’s adjusted loss and LAE ratio, (iii) Ark’s adjusted insurance acquisition expense ratio, (iv) Ark’s adjusted other underwriting expense ratio, (v) Ark’s adjusted combined ratio (vi)~~ Kudu’s earnings before interest, taxes, depreciation and amortization (“EBITDA”), ~~(vii)~~(iii) Kudu’s adjusted EBITDA, ~~(viii)~~(iv) total consolidated portfolio returns excluding MediaAlpha, and ~~(ix)~~(v) adjusted capital, that have been reconciled from their most comparable GAAP financial measures on page ~~74.~~74. White Mountains believes these measures to be useful in evaluating White Mountains’s financial performance and condition.

I. ~~Summary of Operations By Segment~~SUMMARY OF OPERATIONS BY SEGMENT

As of September 30, ~~2022,~~2023, White Mountains conducted its operations through ~~four~~three segments: (1) HG Global/BAM, (2) ~~Ark,~~Ark/WM Outrigger, and (3) Kudu, with our remaining operating businesses, holding companies and ~~(4)~~other assets included in Other Operations. ~~A discussion~~White Mountains has made its segment determination based on consideration of the following criteria: (i) the nature of the business activities of each of the Company’s subsidiaries and affiliates; (ii) the manner in which the Company’s subsidiaries and affiliates are organized; (iii) the existence of primary managers responsible for specific subsidiaries and affiliates; and (iv) the organization of information provided to the Company’s chief operating decision makers and its Board of Directors. Significant intercompany transactions among White Mountains’s ~~consolidated investment operations is included after the discussion of operations by segment.~~segments have been eliminated herein. White Mountains’s segment information is presented in Note 1514 — “Segment Information”to the Consolidated Financial Statements.

As a result of the NSM Transaction, the results of operations for NSM, ~~Group~~previously reported as a segment, have been classified as discontinued operations ~~and are presented separately, net of related income taxes,~~ in the ~~statement~~statements of operations and comprehensive income through the closing of the transaction. ~~Prior year amounts have been reclassified to conform to the current period’s presentation.~~ See Note 19 — “Held for Sale and Discontinued Operations.”

Prior period amounts have been reclassified to conform to the current period’s presentation.

HG Global/BAM

HG Global/BAM consists of the consolidated results of HG Global, HG Re and 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 purpose projects, 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 HG Re, to provide up to 15%-of-par, first loss reinsurance protection for policies underwritten by BAM.

The following tables present the components of pre-tax income (loss) included in ~~White Mountains’s~~the HG Global/BAM segment related to the consolidation of HG Global, which includes HG Re and its other wholly-owned subsidiaries, and BAM for the three and nine months ended September 30, ~~2022~~2023 and ~~2021:~~2022:

HG Global/BAM Results—Three Months Ended September 30, ~~2022~~2023 versus Three Months Ended September 30, ~~2021~~

BAM is required to prepare its financial statements on a statutory accounting basis for the NYDFS and does not report stand-alone GAAP financial results. BAM charges an insurance premium on each municipal bond insurance policy it writes. A portion of the premium is MSC and the remainder is a risk premium. In the event of a municipal bond refunding, a portion of the MSC from original issuance can be reutilized, in effect serving as a credit against the total insurance premium on the refunding of the municipal bond.2022

Gross written premiums and MSC collected in the HG Global/BAM segment totaled $36 million in the third quarter of 2023 compared to $46 million in the third quarter of ~~2022 compared to $28 million~~2022. BAM insured $4.2 billion of municipal bonds, $3.7 billion of which were in the primary market, in the third quarter of ~~2021. BAM insured~~2023 compared to $4.1 billion of municipal bonds, $3.3 billion of which were in the primary market, in the third quarter of 2022. In the third quarter of 2022, BAM completed an assumed reinsurance transaction to reinsure municipal bonds with a par value of $43 million.

Insured penetration in the primary market increased to 7.8% in the third quarter of 2023, driven by demand from both large and small deals, compared to ~~$4.0~~6.2% in the third quarter of 2022.

Total pricing, which reflects both gross written premiums and MSC, decreased to 87 basis points in the third quarter of 2023 compared to 110 basis points in the third quarter of 2022. The decrease in total pricing was driven by lower pricing in the primary market and a decrease in the percentage of par insured in the secondary market, which was partially offset by higher pricing in the secondary market. Pricing in the primary market decreased to 61 basis points in the third quarter of 2023 compared to 79 basis points in the third quarter of 2022. Pricing in the combined secondary and assumed reinsurance markets, which is more transaction specific than pricing in the primary market, increased to 259 basis points in the third quarter of 2023 compared to 229 basis points in the third quarter of 2022.

The following table presents the gross par value of primary and secondary market policies issued, the gross written premiums and MSC collected and total pricing for the three months ended September 30, 2023 and 2022:

(1) Amounts as of ~~a catastrophe loss is a function of both the severity of the event and total amount of insured exposure~~December 31, 2022 for WM Outrigger Re have been reclassified from Other Operations to the ~~event,~~Ark/WM Outrigger segment to conform to the presentation as ~~well as the coverage provided to customers.~~

~~Ark seeks to manage its exposure to catastrophic losses by limiting and monitoring the aggregate insured value~~ of policies in geographic areas with exposure to catastrophic events and by buying reinsurance. To manage, monitor and analyze insured values and potential losses, Ark utilizes proprietary and third-party catastrophe management software to estimate potential losses for many different catastrophe scenarios.

With peak U.S. windstorm season substantially over, Ark’s near-term largest probable maximum loss natural catastrophe scenario on a per occurrence basis at a 1-in-250-year return period is U.S. earthquake. The October 2022 net after-tax estimated impact of a 1-in-250-year return period U.S. earthquake loss represents roughly 25% of Ark’s total tangible capital (shareholders equity and subordinated debt). This net impact is after income taxes, reinstatement premiums, amounts ceded to third-party reinsurers and amounts attributable to TPC Providers.

In addition, Ark also has loss exposures to other global events including, but not limited to, Japanese earthquakes, Japanese windstorms, European windstorms, Southeast U.S. windstorms and U.S. wildfires. Outside of natural catastrophe losses, Ark has exposure to non-natural or man-made large losses. The current largest exposures are cyber, offshore energy production platforms, terrorism events and political risk.September 30, 2023.

IV. Discontinued Operations

NSM

On August 1, 2022, White Mountains closed the NSM Transaction. White Mountains received $1.4 billion in net cash proceeds at closing and recognized a net gain of $876 million, which was comprised of $887 million of net gain from sale of discontinued operations and $3 million of comprehensive income related to the recognition of foreign currency translation gains (losses) from the sale, partially offset by $14 million of compensation and other costs related to the transaction recorded in Other Operations. See Note 2 — “Significant Transactions.”

White Mountains reported net income from discontinued operations, net of tax, for NSM Group of $6 million for the period from July 1, 2022 to August 1, 2022 and $16 million for the period from January 1, 2022 to August 1, 2022.

The net income (losses) from discontinued operations, net of tax, for NSM Group in the first nine months of 2021 included a loss of $29 million related to the sale of a subsidiary. See Note 19 — “Held for Sale and Discontinued Operations.”

~~Sirius Group~~

In the first quarter of 2021, White Mountains recorded an $18 million gain within discontinued operations as a result of reversing a liability arising from the tax indemnification provided in connection with the sale of Sirius Group in 2016 and a $1 million gain related to foreign currency translation. The liability related to certain interest deductions claimed by Sirius Group that had been disputed by the Swedish Tax Agency. In April 2021, the Swedish Tax Agency informed the Swedish Administrative Court of Appeal that Sirius Group should prevail in its appeal (and that the interest deductions should not be disallowed). In June 2021, the Swedish Administrative Court of Appeal ruled in Sirius Group’s favor. See ~~Note 19 — “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 from its insurance, reinsurance and other operating subsidiaries, net investment income, proceeds from sales, repayments and maturities of investments, capital raising activities and, from time to time, proceeds from sales of operating subsidiaries. The primary uses of cash are expected to be general and administrative expenses, purchases of investments, payments to tax authorities, payments on and repurchases/retirements of debt obligations, dividend payments to holders of the Company’s common shares, distributions to ~~non-controlling~~noncontrolling interest holders of consolidated subsidiaries, contributions to operating subsidiaries and, from time to time, purchases of operating subsidiaries and repurchases of the Company’s common shares.

Operating Subsidiary Level

The primary sources of cash for White Mountains’s insurance, reinsurance and other operating subsidiaries are expected to be ~~premiums,~~premium and fee ~~revenues,~~collections, commissions, net investment income, proceeds from sales, repayments and maturities of investments, contributions from holding companies and capital raising activities. The primary uses of cash are expected to be claim payments, policy acquisition costs, general and administrative expenses, broker commission expenses, cost of sales, purchases of investments, payments to tax authorities, payments on and repurchases/retirements of debt obligations, distributions ~~made~~ to holding companies, distributions to ~~non-controlling~~noncontrolling interest holders 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. ~~Premiums,~~Premium and fee ~~revenues,~~collections, investment returns, ~~claims~~claim payments and cost of sales 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’s insurance and reinsurance operating subsidiaries and the settlement of the liability for that loss. The exact timing of the payment of losses cannot be predicted with certainty. White Mountains’s insurance and reinsurance operating subsidiaries maintain portfolios of invested assets with varying maturities and a substantial amount of cash and short-term investments to provide adequate liquidity for the payment of claims.

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

Dividend Capacity

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

HG Global/BAM

As of September 30, ~~2022,~~2023, 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 are entitled to receive cumulative dividends at a fixed annual rate of 6.0% on a quarterly basis, when and if declared by HG Global. As of September 30, ~~2022,~~2023, HG Global has accrued ~~$339~~$399 million of dividends payable to holders of its preferred shares, ~~$327~~$385 million of which is payable to White Mountains and is eliminated in consolidation.

On April 29, 2022, HG Global received the proceeds of its new $150 million, 10-year term loan credit facility. In turn, on May 2, 2022, HG Global paid a $120 million cash dividend to shareholders, of which $116 million was paid to White Mountains.

As of September 30, ~~2022,~~2023, HG Global and its subsidiaries had $3less than $1 million of net unrestricted cash outside of HG Re.

HG Re is a ~~Special Purpose Insurer~~special purpose insurer subject to regulation and supervision by the ~~BMA, but it~~BMA. HG Re does not require regulatory approval to pay ~~dividends. However, HG Re’s~~dividends, however, its dividend capacity is limited to amounts held outside of the Collateral Trusts pursuant to the FLRT with BAM.

Trusts.

On a monthly basis, BAM deposits cash equal to ceded premiums, net of ceding commissions, due to HG Re under the FLRT directly into the Regulation 114 Trust. The Regulation 114 Trust target balance is equal to ~~gross ceded~~HG Re’s unearned premiums and unpaid ~~ceded~~ loss and LAE ~~expenses,~~reserves, if any. If, at the end of any quarter, the Regulation 114 Trust balance is below the target balance, funds will be withdrawn from the Supplemental Trust and deposited into the Regulation 114 Trust in an amount equal to the shortfall. If, at the end of any quarter, the Regulation 114 Trust balance is above 102% of the target balance, funds will be withdrawn from the Regulation 114 Trust and deposited into the Supplemental Trust.

The Supplemental Trust Target Balance is $603 million, less the amount of cash and securities in the Regulation 114 Trust in excess of its target balance. If, at the end of any quarter, the Supplemental Trust balance exceeds the Supplemental Trust Target Balance, such excess may be distributed to HG Re. The distribution will be made first as an assignment of accrued interest on the BAM Surplus Notes and second in cash and/or fixed income securities. 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 Supplemental Trust balance as of September 30, 2023 was $589 million.

As of September 30, ~~2022,~~2023, the Collateral Trusts held assets of ~~$834~~$900 million, which included ~~$458~~$527 million of cash and investments, ~~$365~~$340 million of BAM Surplus Notes and ~~$11~~$33 million of interest receivable on the BAM Surplus Notes.

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.

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.

NON-GAAP FINANCIAL MEASURES

This report includes ~~nine~~five non-GAAP financial measures that have been reconciled with from their most comparable GAAP financial measures.

Adjusted book value per share

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.

The GAAP book value per share numerator is adjusted (i) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global and (ii) to include a discount for the time value of money arising from the modeled timing of cash payments of principal and interest on the BAM Surplus ~~Notes and (ii) to add back the~~Notes.

The value of HG Global’s unearned premium reserve, net of deferred acquisition costs, ~~at HG Global.~~was $187 million, $182 million, $179 million and $172 million as of September 30, 2023, June 30, 2023, December 31, 2022 and September 30, 2022, respectively.

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 BAM Surplus Notes, the present value of the BAM Surplus Notes, including accrued interest and using an 8% discount rate, was estimated to be ~~$114~~$93 million, ~~$120~~$95 million, ~~$130~~$98 million and ~~$132~~$114 million less than the nominal GAAP carrying values as of September 30, ~~2022,~~2023, June 30, ~~2022,~~2023, December 31, ~~2021~~2022 and September 30, ~~2021, respectively.~~

~~The value of HG Global’s unearned premium reserve, net of deferred acquisition costs, was $172 million, $164 million, $159 million and $154 million as of September 30,~~ 2022, ~~June 30, 2022, December 31, 2021 and September 30, 2021,~~ 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 ~~BAM Surplus Notes and the value of the~~ in-force business at HG Re, HG Global’s reinsurance ~~subsidiary.~~subsidiary, and the value of the BAM Surplus Notes.

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. Restricted common shares are earned on a straight-line basis over their vesting periods. The reconciliation of GAAP book value per share to adjusted book value per share is included on page ~~50.~~

~~Ark’s adjusted loss and LAE, adjusted insurance acquisition expense, adjusted other underwriting expense and adjusted combined ratios~~

Ark’s adjusted loss and LAE ratio, adjusted insurance acquisition expense ratio, adjusted other underwriting expense ratio and adjusted combined ratio are non-GAAP financial measures, which are derived by adjusting the GAAP ratios to add back the impact of whole-account quota-share reinsurance arrangements attributable to TPC Providers for the Syndicates. The impact of these reinsurance arrangements relates to years of account prior to the Ark Transaction. White Mountains believes these adjustments are useful to management and investors in evaluating Ark’s results on a fully aligned basis (i.e., 100% of the Syndicates’ results)49. ~~The reconciliation from the GAAP ratios to the adjusted ratios is included on page 60.~~

Kudu’s EBITDA and ~~Kudu’s~~ adjusted EBITDA

Kudu's EBITDA and adjusted EBITDA are non-GAAP financial measures. EBITDA is a non-GAAP financial measure that excludes interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets from GAAP net income (loss). Adjusted EBITDA is a non-GAAP financial measure that excludes certain other items in GAAP net income (loss) in addition to those excluded from EBITDA. The adjustments relate to (i) net realized and unrealized investment gains (losses) on Kudu's Participation Contracts, (ii) non-cash equity-based compensation expense and (iii) transaction expenses. A description of each adjustment follows:

•Net realized and unrealized investment gains (losses) - Represents net unrealized investment gains and losses on Kudu’s Participation Contracts, which are recorded at fair value under GAAP, and realized investment gains and losses on Kudu’s Participation Contracts sold during the period.

•Non-cash equity-based compensation expense - Represents non-cash expenses related to Kudu’s management compensation that are settled with equity units in Kudu.

•Transaction expenses - Represents costs directly related to Kudu’s mergers and acquisitions activity, such as external lawyer, banker, consulting and placement agent fees, which are not capitalized and are expensed under GAAP.

White Mountains believes that these non-GAAP financial measures are useful to management and investors in evaluating Kudu’s performance. The reconciliation of Kudu’s GAAP net income (loss) to EBITDA and adjusted EBITDA is included on page ~~64.~~64.

Total consolidated portfolio return excluding MediaAlpha

Total consolidated portfolio return excluding MediaAlpha is a non-GAAP financial measure that removes the net investment income and net realized and unrealized investment gains (losses) from White Mountains’s investment in MediaAlpha. White Mountains believes this measure to be useful to management and investors by showing the underlying performance of White Mountains’s investment portfolio without regard to MediaAlpha.

The following tables present reconciliations from GAAP to the reported percentages for ~~the~~ three and nine months ended September 30, ~~2022~~2023 and ~~2021:~~2022:

~~Adjusted~~Total adjusted capital

Total capital at White Mountains is comprised of White Mountains’s common shareholders’ equity, debt and ~~non-controlling~~noncontrolling interests other than ~~non-controlling~~noncontrolling interests attributable to BAM. 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 ~~72.~~72.
