Corporate governance is the system by which companies are directed and controlled and involves the distribution of rights and responsibilities among the Board, management and the Company’s Members.  The Company has established Corporate Governance Guidelines that spell out its overall approach towards corporate governance.

The Company also has a Code of Business Conduct that applies to all directors, officers and employees in carrying out their responsibilities to, and on behalf of, the Company.  No waivers of the Code of Business Conduct were requested of, or granted by, the Board for any director or executive officer during 2013.2016.

The Company’s Corporate Governance Guidelines and Code of Business Conduct are available at our website, www.whitemountains.com.  These documents are available in print, free of charge, to any Member upon request.

The Board

The day-to-day management of the Company, including preparation of financial statements and short-term and long-term strategic planning, is the responsibility of management.  The primary responsibility of the Board is to oversee and review management’s performance of these functions in order to advance the long-term interests of the Company and its Members.

In fulfilling this responsibility, directors must exercise common sense business judgment and act in what they reasonably believe to be in the best interests of the Company and its Members.  Directors are entitled to rely on the honesty and integrity of senior management and the Company’s outside advisors and auditors.  However, it is the Board’s responsibility to establish that they have a reasonable basis for such reliance by ensuring that they have a strong foundation for trusting the integrity, honesty and undivided loyalty of the senior management team upon whom they are relying and the independence and expertise of outside advisors and auditors.

Mr.Prior to his retirement on March 1, 2017, Raymond Barrette servesserved as Chairman of the Board and as CEO of the Company.  The Board believes that the most effective leadership structure for the Company at the present time is for Mr. Barrette to serve in both roles.  As CEO, Mr. Barrette iswas effective at overseeing the complex, decentralized operations of the Company.  By virtue of his broad knowledge of the insurance industry and his long experience and track record with the Company, the Board believesbelieved that Mr. Barrette iswas best suited to preside over the Board and set its agendas.  At meetings of the Board at which Mr. Barrette presided as Chairman, Mr. Davis presided over a separate session of non-management directors without Company management present.

Upon Mr. Barrette’s retirement, Mr. Davis was appointed as the Chairman of the Board and Mr. Rountree was appointed as the CEO of the Company.  The Board believes that having an independent Chairman will assist the Board in overseeing Mr. Rountree’s transition to the CEO role.  At meetings of the Board, Mr. Davis presides over a separate session of non-management directors without Company management present.  The Board is composedcomprised of directors that, together, are knowledgeable and experienced in the Company’s business, and the Board is satisfied that the current structure provides strong oversight of the Company’s affairs.

At meetings of the Board, Morgan W. Davis, the Deputy Chairman, presides over a separate session of non-management directors without Company management present.

Director Independence

The Board has determined that a majority of the Company’s current directors are independent, as defined in Section 303A of the New York Stock Exchange (“NYSE”) Listed Company Manual.  Those directors determined to be independent are Messrs. Brouillette, Davis, Frinquelli, Smith and SmithTolman and Ms. Holiday.  For a director to be independent, the Board must determine that the director has no relationship with the Company (other than being a director or shareholder of the Company or its subsidiaries) or has only immaterial relationships with the Company.  The Company does not apply categorical standards as a basis for determining director independence.  Accordingly, the Board considers all relevant facts and circumstances, on a case-by-case basis, in making an independence determination.

The Board notes no current relationships (other than being directors or shareholders) with Messrs. Brouillette, Frinquelli, Tolman and Smith or Ms. Holiday.  The Board notes a relationship with Mr. Davis, as disclosed herein under “Director Compensation”, that it concluded was immaterial and did not impair his independence.  In making its independence determinations, the Board considers all such relationships in light of NYSE standards as well as the attributes it believes should be possessed by independent-minded directors.  Those attributes include the relative impact of the transactions to the director’s personal finances, the perceived degree of dependence by the director or the Company upon the relationship or transactions continuing in the future and whether the transactions were on terms that were reasonable and competitive.

At Sirius Group, long-term incentive compensation is typically in the form of performance units that reward Sirius’ group-wide performance.  The number of units earned at the end of the performance cycle is tied to those elements of performance for which the Sirius Group’s management has primary responsibility.  As an example, because the parent company keeps responsibility for investing Sirius’ assets, in calculating performance it is credited with  Other OneBeacon executives received a “standard” return on its investible assets.  The number of units earned can be from 0x to 2x the target number granted.  In addition, for its most senior executives, in order to better align their interests with those of our shareholders, we typically denominate a portiongreater proportion or all of their long-term incentives in WTM performance units or in long-term cash awards that are tied to the results of OneBeacon’s specialty business as a whole and the executive’s individual business unit.  In 2015, OneBeacon also began denominating a portion of its long-term incentives as OneBeacon restricted shares and/or restricted shares.share units.

We take this approach because producing a rate of return equalHowever, due to a risk-free rate does not add value to the capital owners put in the business—our shareholders would be better off putting their money in U.S. treasuries and avoiding entirely the risk of owning a portion of a business.  We have generally targeted sharing 13% to 17%.  In the 2013-2015 cycle, we increased the sharing at target to 20%.  This was driven by the significant reduction in our capital duefrom the repurchase of 30%44% of our outstanding shares since 2010, andwe increased the new performance share grant madetargeted sharing in some recent cycles up to our CEO.20%.  This year, for the 2014-20162017-2019 cycle, given the current market and interest rate environment, we have maintained this level of sharing.targeted sharing at 14%.  The Committee believes that this level of sharing is appropriate because we compete with private equity and hedge funds for talent and investment opportunities where such sharing is common, the Company’s value adding opportunities are not limited to the Company’s current level of capital, and we want to maintain proper incentives for further share buybacks at value adding prices.

The Committee closely monitors both target and actual value sharing.  From year-to-year when we make new long-term incentive grants, we typically adjust the target number of shares granted to individual employees to reflect the Committee’s assessment of the per share value of the Company.Company, rather than focusing on market values.  In addition, we generally limit total annual share grants to employees to less than 1% of the Company’s outstanding shares.  For each ofboth the 2013-20152016-2018 and 2014-20162017-2019 cycles, we granted slightly in excess of 1% of the outstanding shares, reflecting Mr. Barrette’s grants.adhered to this guideline.

When making new grants, the Committee assesses the impact of different performance scenarios on the potential sharing percentage.  Further, in order to test our beliefs about the size of the awards we make and their variability, annually the Committee has reviewed and considered a systematic analysis prepared by management of the public disclosures about compensation made by other property and casualty insurers and reinsurers and of the amount and variability of compensation at those companies at differing levels of performance.  These analyses have supported the Committee’s view that our compensation programs are appropriately sized and more variable than most other insurers, and reinsurers, have fewer fixed elements of compensation and perquisites, and do not lead to significant rewards for poor performance as can happen with long-term options granted with a fixed exercise price equal to the market price on the date of grant.performance.

The Committee believes that the compensation structures that have been developed for the Company and its subsidiaries closely align the financial interests of management with those of our shareholders and encourage appropriate, but not excessive, risk taking.  In the case of Sirius Group, given its exposure to catastrophic events, beginning in 2008 we implemented a catastrophe spreading mechanism with respect to both its performance units and annual bonus.  This mechanism ensures that Sirius Group is charged with at least 50% of its expected annual catastrophe losses whether or not any catastrophe losses are actually incurred.  Through this mechanism and Sirius Group’s management of its aggregate exposure to very large catastrophic events, the Company’s management and the Committee believe that Sirius Group’s incentive plans are appropriate and do not encourage excessive risk taking.

Our Compensation Process

The Committee is responsible for approving our compensation practices that affect executive officers, and it specifically approves all compensation for our executive officers and for any employee with target annual compensation in excess of $1.5 million.  Our CEO annually presents the Committee with his evaluation of our executives, their individual performances, responsibilities, and the contributions they made to the Company’s accomplishments over the past year, as well as over the last long-term incentive plan cycle and his expectations for the future and succession plans.  In connection with this evaluation, the CEO presents the Committee with his recommendations for establishing the compensation for these executives for its consideration.  The Committee assesses the performance, responsibilities, and contributions of the CEO, considers CEO succession plans, and sets the compensation of the CEO.

With the exception of significant promotions and new hires, compensation matters are usually addressed at the first meeting of the Committee each year (typically late February) following the availability of financial results for the prior year and the current year’s financial plan.  This allows us to determine the results of prior period grants and to set targets for the current year and newest long-term performance cycle.  Performance cycles for long-term compensation typically run for three years beginning on January 1st of the year of grant.

In 2013, becauseBecause Mr. Davis, who was the Chairman of the Committee didin 2016, and Mr. Tolman do not satisfy certain requirements of Section 162(m) to be considered an “outside director” for purposes of that rule, the Committee formed the Performance Compensation Subcommittee (the “Subcommittee”) comprised of the other members of the Committee, each of whom met the requirements to be considered an outside director for purposes of Section 162(m).  The Subcommittee administers and approves all performance-based compensation awards in order to maintain favorable tax treatment of such awards.

Following the OneBeacon initial public offering (the “OB IPO”) in November 2006, the Committee determined that it would fully delegate to the OneBeacon Compensation Committee (the “OneBeacon Committee”) authority for the compensation of OneBeacon’s officers, including those who might be Named Executive Officers of the Company.  Accordingly, compensation actions for OneBeacon personnel following the date of the OB IPO (including new annual and long-term incentives and approval of payouts on existing annual and long-term incentives) have been taken by the OneBeacon Committee (which is currentlyin 2016 was comprised of Lowndes Smith (Chair)(Chairman), Lois Grady and Kent Urness, who are independent directors of OneBeacon, and Mr. Barrette) and, to the extent necessary to comply with applicable regulations, a subcommittee that excludesexcluded Mr. Barrette.

Compensation for 20132016

Our Named Executive Officers in 2016 include Ray Barrette, our Chairman and CEO in 2016, David Foy, Manning Rountree, Robert Seelig, and Reid Campbell.  Allan Waters, who ceased to be an employee of the Company upon the consummation of the sale of Sirius Group in April 2016, also is a Named Executive Officer because he would otherwise have been included as a Named Executive Officer had he still served as an executive officer of the Company as of December 31, 2016.

The principal elements of compensation for our executives are in 2016—long-term incentive compensation, base salary, and annual incentive bonuses.bonuses—are discussed below.

Long-Term Incentive Compensation

CEO.  In 2013,2016, after reviewing Mr. Barrette’s historical compensation, his share ownership, his existing incentives, and the fact that the last tranche of his unvested incentives will vest at the beginning of 2015, compensation granted to CEOs at other property and casualty (re)insurance companies, as well as his delegation to Messrs. Foy and the Company’s performance since Mr. Barrette re-joined in 2007,Rountree of additional day-to-day management responsibilities during 2016, the Subcommittee determined to grant him 12,000 performance5,000 restricted shares for the 2013-20152016-2018 performance cycle.  The grant date market value was approximately $6.8$3.8 million. The number of performance shares that will be earned will be determined after the end of 2015 based on the Company’s performance over the cycle compared to the target described below. The Committee believes that an annual grant of performance shares to Mr. Barrette is the appropriate way to secure his continued employment with the Company and to reward him for performance going forward.

Named Executive Officers.  In the case of Messrs. Foy, Rountree, Seelig and Waters,Campbell, in determining the amount of new long-term incentive compensation grants for 2013,2016, the Committee assessed each executive’s scope of authority and ability to impact the success of the Company.  Based on the Committee’s general experience and the recommendation of the CEO, the Committee established a grant level that it believed was appropriate to reflect each such executive’s expected contribution to the Company over the next performance cycle.  Mr. Miller’s level of compensation was established by the OneBeacon Committee.

For the CEO and eachThe new long-term incentive grants for these Named Executive Officer recipient of a WTMOfficers were allocated 50% as performance shares and 50% as restricted shares, which was the same allocation as in 2015.  At the time the performance share grantgrants were made, the Committee elected not to set a specific performance target to determine the payout on a 0% to 200% scale. With the key job for the 2013-2015Company’s management team being to appropriately deploy the proceeds from the sales of Sirius and Symetra while remaining patient, the Committee determined that grading management’s performance would be best done using judgment at the end of the cycle taking into account all facts the Committee deemed relevant including the Company’s growth in intrinsic business value per share.  The Committee considered many other approaches, including making grants in this cycle entirely in restricted shares, but decided that the chosen approach best fit the unique circumstances of the Company.  However, as discussed below under “2017 Compensation Actions—Establishment of Performance Target for 2016-2018 Performance Share Cycle”, in February 2017 the Committee decided that the benefits of this approach were outweighed by the clarity and cohesion that a single growth in intrinsic value per share target would provide.  As a result, and taking into account the substantial undeployed capital position of the Company, the Committee established 8%a target of 4% annual growth in intrinsic business value per share as the performance target that would result in a payout of 100% of the target shares.  Annual growth of 2% or less would result in a payout of 0% and annual growth of 14% or more would result in a payout of 200%.  The targets were consistent with the Company’s compensation philosophy described above as the yield on the 10-year treasury at the beginning of 2013 was approximately 1.8%.  To measure growth in intrinsic business value per share, the Committee looks to growth in economic value per share (weighted 50%) and growth in adjusted GAAP book value per share (weighted 50%), in each case including dividends.for this cycle.

In total, the WTM performance share and restricted share grants made to all employees of the Company for the 2013-20152016-2018 performance cycle totaled approximately 1%0.8% of the then outstanding shares, slightly in excess ofwithin the Committee’s 1% guideline.

In addition, with respect to the 2011-20132014-2016 performance cycle which matured at the end of 2013, 10%2016, 9% annual growth in intrinsic business value per share (“GIBVPS”) was the performance target for a payout of 100% of the target shares.  Annual growth of 3% or less would have resulted in a payout of 0% and annual growth of 17%15% or more would have resulted in a payout of 200%.  At its meeting in February 2014,March 2017, based on an average annual GIBVPS of 12.1%7.6%, the Committee confirmed that the payout that was earned was 130%76% of target.

David Foy.  Mr. Foy has beenserved as the CFO of the Company since 2003.in 2016.  For the 2011-20132014-2016 cycle, Mr. Foy had been granted 4,2503,000 target performance shares and 4,2503,000 restricted shares.  Based on the Company’s performance over the cycle, he earned 5,5252,280 performance shares.  The restricted shares vested on January 1, 2014.2017.

T. Michael Miller.  Mr. Miller has been the CEO of OneBeacon since 2005.  Based on average annual growth in OneBeacon’s book value per share (“OB GBVPS”) of 6.6% over the 2011-2013 performance cycle, the OneBeacon Committee approved a payout of 37.1% of the OneBeacon performance shares originally granted.  This resulted in a payout of approximately $0.5 million to Mr. Miller.  In addition, based on OneBeacon’s 96.1% adjusted economic combined ratio for the 2011-2013 performance cycle compared to a 94% target, the OneBeacon Committee approved a payout for OneBeacon’s NEOs at 62% of target, which resulted in a payout to Mr. Miller of approximately $1.4 million.  Other participants received payouts at 75.7% of target, reflecting specialty-only results.  The OneBeacon Committee approved an additional payment for Mr. Miller of approximately $0.3 million, which brought Mr. Miller’s total payout to an equivalent of 75.7% of target.

Base Salary

We pay our executive officers salaries that we believe to be below-market.  In 2008, we limited base salaries to a maximum of $500,000.  For 2014, eachEach of our Named Executive Officers currently receives a salary of $500,000.

Annual Incentive Bonuses

We provide annual bonus opportunities to our executive officers.  Each Named Executive Officer participates in the annual bonus pool of his respective business unit.  The aggregate bonus pool size for each business unit could range from 0% to 200% of target, depending upon performance.  Individual bonuses can vary widely around the pool average based on individual performance and no cap (other than the size of the pool) applies to any single individual.  Typically, the head of a business unit receives the average bonus percentage applicable to his business unit.

For 2013,2016, the Named Executive Officers at the WTM level (Messrs. Barrette, Foy and Rountree) had target annual bonuses of 75% of salary, which was unchanged from the prior year.

For Messrs. Barrette, Foy and Rountree,the Named Executive Officers, their annual incentive bonuses are designed to reward company-wide performance.  The Committee did not set a quantitative target in 2016 and instead established the size of the awarded pool based on a qualitative assessment of the Company’s performance during the year based on its judgment.  Based on the Company’s performance in 2013,2016 (excluding the gain from the sale of Sirius), the Committee awarded a bonus pool of 135%90% of target taking into account the Company’s 9.5% growth in adjusted book value per share, 11.3% growth in economic value per share, and its performance in achieving qualitative objectives over the course of the year.  These qualitative objectives included maximizing risk adjusted investment returns, profitably growing OneBeacon, actively pursuing opportunities to improve the long-term position of Sirius Group, ramping up BAM and HG Global, and patiently but actively pursuing capital deployment opportunities.target.  Among the items considered by the Committee were the strong performanceCompany’s 1% growth in adjusted book value per share (excluding the gain from the sale of OneBeacon and Sirius, solid overallSirius), 2% growth in economic value per share (excluding the gain from the sale of Sirius), the repurchase of approximately 20% of the Company’s outstanding shares at an average price per share of $802, the large amount of undeployed capital held by the Company, investment performance, results at Sirius prior to the startup performanceclosing of BAMthe sale and at OneBeacon, the continued progress at BAM/HG Global in challenging market conditions, and the Life Re novation at Sirius Group.gain on the sale of Tranzact.  Messrs. Barrette, Foy, Rountree, Seelig and Rountree receivedCampbell were awarded bonuses of $500,000, $500,000$337,500, $315,000, $315,000, $315,000 and $700,000,$315,000, which represented 133%90%, 133%84%, 84%, 84% and 207%84% of target.

For OneBeacon, including for Mr. Miller, the primary performance objective required to achieve a bonus pool of 100% of target was the achievement of a combined ratio of 93.2% or better, including parent company expenses.  OneBeacon’s actual combined ratio was 93.0%.  The OneBeacon Committee also considered the 17.3% growthCompany in OneBeacon’s book value per share achieved during 2013 as well as qualitative goals including optimizing capital management, the status ofconnection with the sale of its runoff operations and managing and executing against the expense plan.  Based on its assessment of OneBeacon’s overall performance in 2013, the OneBeacon Committee establishedSirius Group, Mr. Seelig received a bonus pool of 125% of target.  It awarded Mr. Miller a cashspecial bonus of $468,800, which equaled 125% of target.$2,000,000.

20142017 Compensation Actions

New Long-termLong-Term Incentive Grants and Annual Bonus TargetsProgram

In February 2014,2017, the Committee and the OneBeacon Committee, as applicable,Subcommittee made new long-term incentive grants to and established annual bonus target levels for the Named Executive Officers (other than Messrs. Barrette, Foy and Waters) based on the same factors described above with respect to grants made in 2013.2016.

The new long-term incentive grants for White Mountains executives (other than Mr. Barrette and operating company executives) were allocated 50% as performance shares and 50% as restricted shares, which was the same allocation as in 2013.2016.

For each Named Executive Officer recipient of a WTM performance share grantWith approximately $1.8 billion remaining in undeployed capital, deploying capital intelligently remains the key job for the 2014-2016 performance cycle,Company’s management team.  Taking account of the level of deployed and undeployed capital (and current expected runrate returns thereon) and reasonable assumptions regarding the timing and magnitude of redeployment and distributions of undeployed capital, the Committee established 9%determined that 5% annual growth in intrinsic business value per share as the performanceis an appropriately challenging target that would result infor a payout of 100% of the target shares.shares for the 2017-2019 performance cycle.  The Committee believes this target properly balances the competing incentives (i) to deploy or distribute undeployed capital aggressively and (ii) to remain patient for strong opportunities.  Annual growth of 3%1% or less would result in a payout of 0%, and annual growth of 15%9% or more would result in a payout of 200%.  To measure growth in intrinsic business value per share, the Committee looks to growth in economic value per share (weighted 50%) and growth in adjusted GAAP book value per share (weighted 50%), in each case including dividends.  The yield onCommittee expects targets for future performance share cycles to increase as the 10-year Treasurylevel of undeployed capital normalizes over time.

Establishment of Performance Target for 2016-2018 Performance Share Cycle

When originally granted, the Committee did not set a performance target for the 2016-2018 performance cycle.  Instead, management’s performance would be graded using judgment at the beginningend of 2014 was about 3.0%the cycle.  As discussed above under “Compensation for 2016—Long-Term Incentive Compensation”, at its meeting on March 1, 2017, the Committee established a performance target for the 2016-2018 performance share cycle of 4% annual growth in intrinsic business value per share with annual growth of 0% or less resulting in a payout of 0% and annual growth of 8% or more resulting in a payout of 200%.  In setting thethis target, at 9%, which equaled the yield on the 10-year Treasury + roughly 600 basis points, the Committee considered many factors including its typical practice of adding roughly 700 basis points to the yield as well as the historically low interest rate environment.  In addition, the Committee considered the impactsame factors that it considered in setting the target for the 2017-2019 performance share cycle. The Committee decided to establish a performance target as it determined that the clarity and cohesion that a single growth in intrinsic value per share target provides outweighed the benefits of using judgment at the end of the cycle to set the payout level.

Retirement of Ray Barrette

Mr. Barrette retired as Chairman and CEO on March 1, 2017.  In connection with his retirement, as more fully described in the Company’s undeployed capitalCurrent Report on expected returns.Form 8-K dated March 1, 2017, the Company entered into a letter agreement (the “Agreement”) with Mr. Barrette pursuant to which it agreed to pay Mr. Barrette (i) a cash bonus for 2017 equal to $187,500 and (ii) a cash retirement payment equal to approximately $21 million.  Mr. Barrette’s unvested long term performance shares and restricted shares were canceled in connection with his retirement. The Committee determinedAgreement also provides that 9% was an appropriate targetMr. Barrette will be subject to certain restrictive covenants regarding competition, solicitation and disparagement that properly balanced the competing demands of effectively deploying capital and remaining patient for great opportunities.apply through December 31, 2018.

Clawback Policy

In 2010, theThe Company has adopted a clawback policy applicable to bonuses and long-term incentive awards.  If the Company is required to restate any financial statement included in an SEC filing as a result of an employee’s misconduct, the Board may, without prejudice to any other remedies available to the Company, seek reimbursement of any bonus or long-term incentive award received by such person that relates in whole or in part to any period for which such financial statements were restated.  If the misconduct was fraud, then in addition to other actions the Board mandatorily will seek such reimbursement.

Other Elements of Compensation

Retirement Benefits

We have no active U.S. defined benefit pension plans.  Benefit accruals under all our U.S. qualified defined benefit pension plans and all our U.S. supplemental defined benefit pension plans were frozen for all employees in 2002.

Our Named Executive Officers who are not employees of Bermuda-domiciled entities may participate in our voluntary non-qualified deferred compensation plans whereby they may defer all or a portion of their compensation.  Investment options in these plans are those available in our 401(k) plans, including White Mountains common shares and OneBeacon common shares.  None of the investment options offered under these plans provides an above-market rate of interest.

Our employees may participate in our qualified 401(k) plans and eligible employees can participate in a qualified employee stock ownership plan.  We do not provide supplemental retirement benefits to any employees in connection with these plans.

Perquisites

We review the perquisites that our senior management receives.  The primary perquisites include housing allowances in special circumstances and personal use of corporate aircraft.

We allow our Named Executive Officers to use our corporate aircraft from time to time for personal reasons.  The aggregate incremental cost to the Company is included, for proxy reporting purposes, as compensation to the Named Executive Officer.  For tax purposes, we comply with IRS regulations.  We do not “gross-up” our Named Executive Officers for their taxes associated with perquisites, including with respect to personal use of our aircraft.

Our Named Executive Officers also participate in our other benefit plans on the same terms as our other employees.  These plans include medical and health insurance, company paid life insurance and charitable gift matching.

Certain Board Fees

Our Named Executive Officers do not receive director fees for serving on the Company’s board of directors or for serving on the boards of directors of our wholly-owned or majority-owned subsidiaries.  However, those Named Executive Officers who serve on the boards of directors of other companies in which we have a minority interest may receive director fees.  We consider those board fees when evaluating the compensation of our Named Executive Officers.

Employment and Severance Agreements; Change in Control

We have no long-term employment agreements with our Named Executive Officers although, from time to time, we have entered into short-term arrangements with newly hired executives governing their compensation and severance during up to their first three years with the Company.  No such arrangements are in effect with our Named Executive Officers.

At our parent company, severance benefits, if any, are determined by the Committee in its sole discretion.  At our operating subsidiaries, our Named Executive Officers participate in the severance plans, if any, generally applicable at those companies.

If any of our most senior executives were to retire, in order to enable the Company to ensure a smooth transition, to receive a non-compete/non-solicit from the executive and to retain access to valuable knowledge, talents and relationships, we generally will consider entering into a one to three yearthree-year consulting agreement with the executive, which would permit the executive to earn some or all of such executive’s long-term incentive compensation then outstanding.

While the Company has no employment or severance agreement with Mr. Barrette, pursuant to the terms of his grants discussed above under “Philosophy”, if Mr. Barrette is terminated without cause, any unvested restricted shares would vest in such circumstance.

We have no standalone change in control agreements with our Named Executive Officers.  However, under our long-term incentive plans, if a change in control of the Company (or a business unit, as applicable) were to occur, certain events, such as involuntary or constructive employment termination or amendments to our incentive plans which are materially adverse to its participants, may cause stock options to become fully exercisable, restricted shares to become immediately vested and performance shares and performance units to become payable in full or in part.  Our plans do not provide for tax gross-ups for excess parachute payments that may result from a change in control.

The option and restricted share grants made to Mr. Barrette in 2007 include provisions pursuant to which such grants vest upon the occurrence of a change in control.  While the Company typically has “double-trigger” change in control provisions in its long-term incentive plans, when originally making those grants to Mr. Barrette, the Committee determined that, in light of the design of Mr. Barrette’s grants and as an inducement to Mr. Barrette, immediate vesting upon a change in control was appropriate.

Tax Considerations

As a Bermuda-domiciled company, we do not receive a tax deduction for compensation paid to employees of White Mountains Insurance Group, Ltd. and, accordingly, the limitation of Section 162(m) does not impact compensation paid to our Named Executive Officers who are employees of non-U.S. companies (Messrs. Barrette, Foy, Rountree, Seelig, Campbell and Waters).  However, in the case of Named Executive Officers who are employees of subsidiaries that are organized in the United States (Messrs. Miller and Rountree)(Mr. Campbell), Section 162(m) limits the deductibility of their compensation to $1,000,000 per individual to the extent that such compensation is not “performance-based” as defined in Section 162(m).  The Company is cognizant of Section 162(m) and generally seeks to structure its long-term incentive programs to permit the deductibility of the bulk of such compensation paid to these Named Executive Officers.  However, the Committee may approve compensation that will not meet the Section 162(m) requirements if, in the Committee’s judgment, structuring compensation in such manner better promotes the Company’s interests (such as with a grant of restricted shares)shares and in the case of the grant of the 2016-2018 performance share cycle).

The Compensation Committee of the Company has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.
