THE ANNUAL GENERAL MEETING

We are furnishing this proxy statement to holders of our common shares in connection with the solicitation of proxies by our Board of Directors at the annual general meeting, and at any adjournments and postponements of the meeting.

Internet Availability of Proxy Materials

Important Notice Regarding the Availability of Proxy Materials for the Annual General Meeting of Shareholders to be held on May 6, 2016 : this proxy statement and 2015 Annual Report to Shareholders are available at: www.proxyvote.com.

We are furnishing proxy materials to our shareholders primarily via the internet. On or about March 24, 2016 , we expect to mail to our shareholders a Notice of Internet Availability containing instructions on how to access our proxy materials, including our proxy statement and 2015 Annual Report to Shareholders. The Notice of Internet Availability also will instruct you on how to access and submit your proxy through the internet or by telephone.

Internet distribution of our proxy materials is intended to expedite receipt by shareholders, reduce the cost of the annual meeting, and conserve natural resources. However, if you would like to receive printed proxy materials, please follow the instructions on the Notice of Internet Availability.

Time and Place

The annual general meeting of Arch Capital Group Ltd. (“ACGL,” “we,” or the “Company”) will be held at 8:45 a.m. (local time) on May 6, 2016 at the Company’s offices located at Waterloo House, Ground Floor, 100 Pitts Bay Road, Pembroke HM 08, Bermuda.

Record Date; Voting at the Annual General Meeting

Our Board of Directors has fixed the close of business on March 8, 2016 as the record date for determination of the shareholders entitled to notice of and to vote at the annual general meeting and any and all postponements or adjournments of the meeting. On the record date, there were 122,085,692 common shares outstanding and entitled to vote, subject to the limitations in our bye-laws described below. At that date, there were an estimated 1,052 holders of record and approximately 29,600 beneficial holders of the common shares. Each holder of record of shares on the record date is entitled to cast one vote per share, subject to the limitations described below. A shareholder may vote in person or by proxy submitted by mail, telephone or internet, on each proposal put forth at the annual general meeting. Only holders of the Company’s common shares may vote at the annual general meeting. The Company’s outstanding preferred shares have no voting rights (except in very limited circumstances which do not currently apply).

Limitation on Voting Under Our Bye-Laws

Under our bye-laws, if the votes conferred by shares of the Company, directly or indirectly or constructively owned (within the meaning of Section 958 of the Internal Revenue Code of 1986, as amended (the “Code”)), by any U.S. person (as defined in Section 7701(a)(30) of the Code) would otherwise represent more than 9.9% of the voting power of all shares entitled to vote generally at an election of directors, the votes conferred by such shares or such U.S. person will be reduced, subject to certain exceptions, by whatever amount is necessary so that after any such reduction the votes conferred by the shares of such person will constitute 9.9% of the total voting power of all shares entitled to vote generally at an election of directors. There may be circumstances in which the votes conferred on a U.S. person are reduced to less than 9.9% as a result of the operation of our bye-laws because of shares that may be attributed to that person under the Code.

Notwithstanding the provisions of our bye-laws described above, after having applied such provisions as best as they consider reasonably practicable, the Board of Directors may make such final adjustments to the aggregate number of votes conferred by the shares of any U.S. person that they consider fair and reasonable in all the circumstances to ensure that such votes represent 9.9% of the aggregate voting power of the votes conferred by all shares of ACGL entitled to vote generally at an election of directors.

In order to implement our bye-laws, we will assume that all shareholders are U.S. persons unless we receive assurances satisfactory to us that they are not U.S. persons.

Table of Contents

Quorum; Votes Required for Approval

The presence of two or more persons representing, in person or by proxy, including proxies properly submitted by mail, telephone or internet, not less than a majority of the voting power of our shares outstanding and entitled to vote at the annual general meeting is necessary to constitute a quorum. If a quorum is not present, the annual general meeting may be adjourned from time to time until a quorum is obtained. The affirmative vote of a majority of the voting power of the shares represented at the annual general meeting will be required for approval of each of the proposals, except that Proposal 1 will be determined by a plurality of the votes cast, and Proposal 6 is advisory and does not have a required vote.

An automated system administered by our distribution and tabulation agent will tabulate votes cast by proxy at the annual general meeting, and our inspector will tabulate votes cast in person. Abstentions and broker non-votes ( i.e ., shares held by a broker which are represented at the meeting but with respect to which such broker does not have discretionary authority to vote on a particular proposal) will be counted for purposes of determining whether or not a quorum exists. Abstentions will be considered in determining the number of votes necessary for Proposals 2, 3, 4 and 5.

Several of our officers and directors will be present at the annual general meeting and available to respond to questions. Our independent auditors are expected to be present at the annual general meeting and will have an opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

Voting and Revocation of Proxies

All shareholders should follow the instructions on the Notice of Internet Availability to access and submit your proxy through the internet or by telephone or, if you received printed proxy materials, complete, sign, date and return the enclosed proxy card. All shares represented at the annual general meeting by proxies, including proxies properly submitted by mail, telephone or internet, received before or at the annual general meeting, unless those proxies have been revoked, will be voted at the annual general meeting, including any postponement or adjournment of the annual general meeting. If no instructions are indicated on a properly executed proxy, the proxies will be deemed to be in accordance with the recommendation of the Board of Directors with respect to each of the proposals described in this proxy statement.

Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by either:


•	filing, including by facsimile, with the Secretary of the Company, before the vote at the annual general meeting is taken, a written notice of revocation bearing a later date than the date of the proxy or a later-dated proxy relating to the same shares, including proxies properly submitted by mail, telephone or internet; or


•	attending the annual general meeting and voting in person.

In order to vote in person at the annual general meeting, shareholders must attend the annual general meeting and cast their vote in accordance with the voting procedures established for the annual general meeting. Attendance at the annual general meeting will not in and of itself constitute a revocation of a proxy. Any written notice of revocation or subsequent proxy must be sent so as to be delivered at or before the taking of the vote at the annual general meeting to Arch Capital Group Ltd., W aterloo House, Ground Floor, 100 Pitts Bay Road, Pembroke HM 08, Bermuda, facsimile: (441) 278-9255, Attention: Secretary.

Solicitation of Proxies

Proxies are being solicited by and on behalf of the Board of Directors. In addition to the use of the mail, proxies may be solicited by personal interview, telephone, telegram, facsimile and advertisement in periodicals and postings, in each case by our directors, officers and employees.

We have retained MacKenzie Partners, Inc. to aid in the solicitation of proxies and to verify records related to the solicitation. We will pay MacKenzie Partners, Inc. fees of not more than $11,000 plus expense reimbursement for its services. Brokerage houses, nominees, fiduciaries and other custodians will be requested to forward solicitation materials to beneficial owners and will be reimbursed for their reasonable expenses incurred in so doing.

Please contact MacKenzie Partners at 800-322-2885 with any questions you may have regarding our proposals.

Board of Directors

Leadership Structure

The Board reviews the Company’s leadership structure from time to time, and currently combines the role of chairman of the board and chief executive officer, together with an independent lead director to strengthen our corporate governance structure. We believe that the combined role of chairman and chief executive officer under Mr. Iordanou promotes unified leadership and direction for the Company, which provides a single, clear focus for management to execute the Company’s strategy and business plan. This structure also fosters clear accountability and effective decision making. We believe that the combined role of chairman and chief executive officer, together with an independent Board, including an independent lead director, provides at this time an appropriate balance between strategy development and independent oversight of management.

Several factors ensure that we have a strong and independent Board. As indicated below, all directors, with the exception of Messrs. Iordanou and Vollaro, are independent as defined under the applicable listing standards of The NASDAQ Stock Market LLC (“NASDAQ”), and the audit, compensation and nominating committees of our Board are composed entirely of independent directors. The Company’s independent directors bring experience, oversight and expertise from many industries, including the insurance industry. In addition to feedback provided during the course of Board meetings, the independent directors regularly meet in executive session without management present. The Board also has regular access to our management team.

The lead director coordinates the activities of the other non-management/independent directors, and performs such other duties and responsibilities as the Board may determine. The lead director presides at all meetings of the Board at

Table of Contents

which the chairman of the board is not present, including executive sessions of the non-management/independent directors, and has the authority to call meetings of the non-management/independent directors. The lead director also serves as principal liaison between the chairman of the board and the non-management/independent directors and works with the chairman of the board to develop an appropriate schedule of Board meetings and to establish the agendas for Board meetings. In addition, the lead director advises the chairman of the board as to the quality, quantity and timeliness of the flow of information from the Company’s management that is necessary for the independent directors to effectively and responsibly perform their duties. The lead director is also available, when appropriate, for consultation and direct communication with major shareholders.

Board Independence and Composition

The Board of Directors is required to determine which directors satisfy the criteria for independence under the rules of NASDAQ. To be considered independent, a director may not maintain any relationship that would interfere with his or her independent judgment in completing the duties of a director. The rules state that certain relationships preclude a board finding of independence, including a director who is, or during the past three years was, employed by the company, and any director who accepts any payments from the company in excess of $120,000 during the current year or any of the past three years, other than director fees or payments arising solely from investments in the company's securities. The rules specifically provide that ownership of company stock by itself would not preclude a board finding of independence. Our Board of Directors consists of eleven directors, including nine non-employee directors. Our Board of Directors has concluded that the following nine non-employee directors are independent in accordance with the director independence standards set forth in Rule 5600 of the rules of NASDAQ: J ohn L. Bunce, Jr., Eric W. Doppstadt, Kewsong Lee, Yiorgos Lillikas, Deanna M. Mulligan, Louis J. Paglia, John M. Pasquesi, Brian S. Posner and Eugene S. Sunshine. In making these independence determinations, the Board reviewed the relationships with the directors set forth under the captions “Compensation Committee Interlocks and Insider Participation” and “Certain Relationships and Related Transactions,” including ordinary course transactions not meeting the disclosure threshold with insurers, reinsurers and producers in which a director or a fund affiliated with any of our directors maintained at least a 10% ownership interest.

Role in Risk Oversight

Our Board, as a whole and also at the committee level, has an active role in overseeing management of the Company’s risks. The Board regularly reviews information regarding the Company’s business and operations, including with respect to underwriting, investments, capital management, liquidity, financial reporting and compliance, as well as the risks associated with these activities. Committees of the Board help oversee the business and operations of the Company. The underwriting oversight committee oversees risks relating to our underwriting activities, including with respect to accumulations and aggregations of exposures in our insurance, reinsurance and mortgage businesses. The members of the underwriting oversight committee regularly participate in the underwriting review meetings held in our insurance, reinsurance and mortgage operations. The audit committee oversees management of financial reporting and compliance risks. The compensation committee is responsible for overseeing the management of risks relating to the Company’s compensation plans and arrangements, retention of personnel and succession planning. The finance, investment and risk committee oversees risks relating to the financial, investment and risk affairs of the Company. The nominating committee oversees risks associated with the composition of the Board of Directors. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board of Directors is regularly informed through committee reports about such risks. Please refer to “Committees of the Board of Directors.”

Code of Business Conduct, Committee Charters and Corporate Governance Guidelines

We have adopted a Code of Business Conduct, which describes our ethical principles, and charters of responsibilities for our standing Board committees, including underwriting oversight, audit, compensation, executive, finance, investment and risk and nominating committees. We have also adopted Corporate Governance Guidelines that cover issues such as executive sessions of the Board of Directors, director qualification and independence requirements, director responsibilities, access to management, evaluation and communications with the Board in order to help maintain effective corporate governance at the Company.

Report of the Audit Committee of the Board of Directors

Compensation Discussion and Analysis

Introduction

In this section, we discuss the principal aspects of our compensation program as it pertains to Constantine Iordanou, Chairman of the Board and Chief Executive Officer of ACGL; Mark D. Lyons, Executive Vice President, Chief Financial Officer and Treasurer of ACGL; and our three other most highly-compensated executive officers in 2015 , Marc Grandisson, President and Chief Operating Officer of ACGL, David H. McElroy, Chairman and Chief Executive Officer of Arch Worldwide Insurance Group and Arch Insurance Group, and W. Preston Hutchings, President of Arch Investment and Senior Vice President and Chief Investment Officer of ACGL. We refer to these individuals throughout this section as the “named executive officers.” Our discussion focuses on our compensation and practices relating to 2015 .

The compensation committee of our Board of Directors (which we refer to as the “Committee” in this section) is responsible for determining and approving the individual elements of total compensation paid to the chief executive officer and our other executive officers and establishing overall compensation policies for our employees. The Committee also oversees the administration of executive compensation plans and certain employee benefits. Our Board of Directors appoints each member of the Committee and has determined that each is an independent director under the applicable standards of NASDAQ.

Executive Summary

We seek to attract and retain quality executives who will contribute to our long-term success and help us to manage all phases of the underwriting cycle. We seek to provide a compensation program that is driven by our overall financial performance and the increase in shareholder value.

Increase in Shareholder Value. During 2015, our common share price increased 18% and out-performed the annual return of the S&P 500 Composite Stock Index (“S&P 500 Index”) and the S&P 500 Property & Casualty Insurance Index, which returned 1.4% and 9.5%, respectively. Our performance has also been strong over the longer term. For example, our common share price appreciated by 18.9% on a compound annualized basis over the past five years, compared to the total stock return for the S&P 500 Index and the S&P 500 Property & Casualty Insurance Index, of 12.6% and 16%, respectively. We believe our compensation program’s emphasis on performance-based and share-based pay contributes to our success in building shareholder value.

The principal features of our compensation programs and policies are summarized below. Please refer to the balance of this discussion for additional details.


•	Key Principles. The main principles of our strategy include the following: (1) compensation decisions are driven by performance, (2) increased compensation is earned through an employee’s increased contribution and (3) a majority of total compensation should consist of variable, performance-based compensation.

•

Emphasis on Performance-Based Incentives. Our compensation program includes both fixed and variable compensation, with an emphasis on long-term compensation that is tied to Company performance. Although we do not apply rigid apportionment goals in our compensation decisions, our philosophy is that variable pay, in the form of annual cash incentive bonuses and share-based awards, should constitute the majority of total direct compensation.

•

Pay-Mix. In 2015 , for our named executive officers, we allocated compensation as follows: (1) base salaries ranging from approximately 10% to 27% of total compensation and (2) variable, performance-based compensation, in the form of annual cash incentive bonuses and long-term incentive share-based awards, ranging from approximately 73% to 90% of total compensation, as described below. The variable performance-based compensation component of our chief executive officer’s total compensation was 90% . In addition, our chief executive officer elected to receive 100% of his cash bonus for 2015 in the form of stock options, with an exercise price equal to the closing stock price on the grant date. Share price appreciation over an extended period of time will be required in order for Mr. Iordanou to realize any compensation benefit from this significant component of his 2015 compensation.

•

Share-Based Awards. A substantial component of variable compensation is granted in the form of annual multi-year vesting share-based awards, which make stock price appreciation over an extended period of time fundamental in realizing a compensation benefit. By emphasizing long-term performance through using long-term incentives, we align our executives’ interests with our shareholders’ interests and create a strong retention tool. The Company

provides awards in the form of restricted share/unit grants and stock options and share-settled stock appreciation rights (“SARs”), which typically provide for vesting over three years.

Key Metrics and Other Performance Measures. The Committee uses a structured and disciplined approach to assess performance for the purpose of making compensation decisions. The Committee considers both financial performance and strategic objectives in its evaluation process, and generally does not use pre-set performance goals. Instead, the Committee (i) reviews performance on an annual basis using the portfolio of metrics summarized below, and (ii) applies its business judgment to determine bonuses and the overall amount and mix of compensation elements. The Committee believes this structured and disciplined evaluation process in administering the Company’s compensation programs enables us to respond more flexibly to changes in the business environment as well as the Company’s operations. The two key financial metrics considered by the Committee are growth in book value per share, which creates long-term shareholder value, and return on equity (“ROE”) a key driver of book value growth. The Committee emphasizes operating ROE (“Operating ROE”), which drives book value growth, produces a stable stream of earnings in the short term and is a key indicator of the efficient use of capital. Operating ROE measures the Company’s returns after excluding non-operating items such as investment gains and losses and foreign exchange gains and losses. The Committee also considers our ROE based on net income (“Net income ROE”), which includes these items and contributes more directly to value creation and book value growth over time. In addition, Net income ROE reflects the impact of the Company’s investment philosophy of maximizing total returns in our portfolio. Total return on investments includes net investment income, net realized gains and losses, changes in unrealized gains and losses, and equity in the net income or losses of investment funds accounted for using the equity method. The Committee also takes into account total stock return, after-tax operating income, our underwriting returns and investment performance. The Committee measures Company performance based on an analysis of our financial performance on an absolute basis and as compared to that of Selected Competitors (as defined below in “Committee Review”) over one, three, five and ten year periods. In determining the performance-based compensation of our chief executive officer and other named executive officers, the Committee reviews the estimated bonus pool determined under a quantitative, formula-based measure (referred to as the “Formula Approach”) included in our Incentive Compensation Plan. These calculations are based on ROE targets for the current and prior underwriting years. The Committee also considers the achievement of strategic objectives and support of our values by promoting a culture of integrity through compliance with law and our ethics policies.

•

Risk Management. We believe our approach to evaluation of performance and the design of our compensation programs assists in mitigating excessive risk-taking that could harm our Company. We emphasize variable compensation that is tied to Company performance. For senior management, we emphasize long-term compensation that vests over a multi-year period. Furthermore, and as discussed above, the Formula Approach included in our Incentive Compensation Plan, which is applied to employees in our insurance, reinsurance and mortgage segments and is reviewed in connection with compensation decisions relating to our named executive officers, is based on underwriting performance during a given underwriting year. For each underwriting year, the bonus pool will be recalculated annually as actual underwriting results emerge, and any resultant payments will be made to the participants over a 10-year development period. Since much of our business requires multiple years to determine whether we have been successful in our assessment of risk, we have structured our plan in this manner so that incentive payments are made to employees as actual results become known. In addition, senior management is subject to our clawback policy and share ownership guidelines with hedging/pledging restrictions.

•

Double Trigger Change-in-Control Arrangements. In the event of a change in control, the employment agreements with our named executive officers require an involuntary or constructive termination of the executive’s employment in order for severance payments to be made. Similarly, the current annual award agreements for the named executive officers provide that unvested shares and unvested options/SARs do not vest immediately upon a change in control. Rather, in the event that the employee’s employment is terminated by the Company other than for cause or by the employee for good reason within two years following the consummation of a change in control (“double trigger”), unvested shares and unvested options/SARs would immediately vest, and the options/SARs would have a remaining term of 90 days from termination. These provisions are consistent with our objective of providing employees with a level of financial protection upon loss of employment.


•	No Excise Tax Gross-Ups . We do not provide excise tax gross-ups to any of our executives.


•	Complementary Governance Policies and Practices. The Company’s compensation philosophy and related governance features are complemented by several specific elements that are designed to align our compensation with long-term shareholder interests, which are outlined below and described in more detail in this proxy statement.

Table of Contents


•	Clawback Policy. Our clawback policy covers all executive officers, including the chief executive officer, and provides for affected incentive-based compensation to be recouped by the Company in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws.

•

Share-Based Awards. Our share-based awards generally require, at minimum, one year vesting, exercisability and distribution provisions. Share-based awards generally may not be accelerated except for death, disability and change in control. Our plans do not permit liberal share recycling, granting of SARs or stock options at an exercise price below the fair market value on the grant date, do not allow for repricing or reducing the exercise price of a stock option or SAR, and also do not permit repurchases of out-of-the-money stock options. We set the exercise price of stock options and SARs at the closing share price on the date of grant.

•

Share Ownership Guidelines for Executives and Directors. The Company has share ownership guidelines that require our senior executives and the directors to maintain common share ownership levels as follows: (1) chief executive officer of ACGL—six times base salary; (2) named executive officers and other executives who file reports under Section 16 of the Exchange Act and certain other members of senior management designated from time to time—four times base salary; and (3) other designated members of senior operating management—three times base salary. Individuals subject to these guidelines have five years to meet the applicable minimum requirement.

•

Share Holding Requirements for Executives and Directors. We require each of our senior executives and directors to retain an amount equal to 50% of the net profit shares received from Company equity awards until he or she has attained the applicable share ownership level. Net profit shares are the shares remaining after payment of the exercise price of an option and taxes owed on exercise of options or SARs, vesting of restricted stock, or vesting and payout under restricted stock units and performance shares.


•	No Hedging Permitted. Our named executive officers, other members of senior management and our directors are not permitted to engage in hedging activities with respect to the Company’s securities.

•

Code of Business Conduct, Committee Charters and Corporate Governance Guidelines . We have adopted a Code of Business Conduct, which describes our ethical principles, and charters of responsibilities for all of our standing Board committees. We have also adopted Corporate Governance Guidelines that cover issues such as executive sessions of our Board of Directors, director qualification and independence requirements, director responsibilities, access to management, evaluation and communications with the Board in order to help maintain effective corporate governance at the Company.

•

Executive Sessions. The Committee meets in executive sessions (without management present) as necessary, particularly when administering any aspect of the compensation program for the chairman and chief executive officer of ACGL. Compensation matters in respect of the chairman and chief executive officer of ACGL, the chief financial officer of ACGL and other members of senior management are subject to ratification by our Board of Directors.

2015 Highlights

The 2015 year was challenging not only because of price softness in some areas but also due to investment market volatility and continued low yields, which affected our investment results. We navigated a complex market environment in which each of our three business segments encountered its own distinct conditions. Our reinsurance segment faced the strong headwinds of industry overcapacity and weak pricing. By contrast, our mortgage segment enjoyed strong tailwinds as we continued to build this relatively new segment of the Company. Market conditions for insurance, our largest segment, were in-between: the prevailing winds were mostly calm, although some product lines came under pricing pressure in the second half of the year. We continued to exercise underwriting discipline in 2015, as we invested our capital into our diversified mix of business, which gave us the flexibility to increase our writings in those areas offering the best potential returns and reduced our writings where pricing was weak. Our performance measures discussed below exclude the results of Watford, in which we own an approximately 11% equity interest.

•	Our stock price increased 18%, and closed at $69.75 at December 31, 2015, and at year end our price to book value was approximately 145%.


•	Key Metrics. Our book value per share increased by 5.2% , to $47.95 at December 31, 2015 , the Company’s seventh consecutive annual increase. Over the past decade, book value per share has grown at a compound annual rate of 15.6% . Compared with our Selected Competitors, we ranked sixth for annual growth in book value per share and second over the ten year period.

Our Operating ROE and Net income ROE in 2015 were 9.7% and 8.8% , respectively, both down from 2014 levels, reflecting the impact of more difficult market conditions. Over the past decade, our Operating ROE and Net income ROE have averaged 14.4% and 15.9% per year, respectively. We ranked eighth and sixth, respectively among our Selected Competitors for 2015, and second among our Selected Competitors during the ten year period on both measures.

Common Stock Performance. As of December 31, 2015 , the closing price for our common shares was $69.75, an increase of 18% from 2014. As indicated in the graph below, during 2015, our common stock outperformed the annual return of the S&P 500 Index and the S&P 500 Property & Casualty Insurance Index, which returned 1.4% and 9.5%, respectively. In addition, at December 31, 2015 and 2014 , our common share price represented an approximately 145% and 130% premium to our book value per share (“Share Price Multiple”). For the property and casualty industry, price to book value is viewed as an important indicator of company performance by analysts and the investment community. At December 31, 2015 , our Share Price Multiple was second among our Selected Competitors. Our performance has also been strong over the longer term, as well. For example, our common share price appreciated by 18.9% on a compound annualized basis over the past five years, compared to the total stock return for the S&P 500 Index and the S&P 500 Property & Casualty Insurance Index, of 12.6% and 16%, respectively. Both on an annual basis and for the five-year period, our total stock return, which assumes reinvestment of dividends, was second among our Selected Competitors. In addition, our common share price appreciated by 14.3% on a compound annualized basis over the past ten years, which was first among our Selected Competitors.

Capital Management. Total capital was $7.10 billion at the end of 2015, up slightly from $7.02 billion a year earlier. Debt and hybrids represented 17.1% of total capital at the end of 2015 and 17.3% at the end of 2014. Disciplined capital management is a core element of our business philosophy. We maintain a conservative balance sheet with modest leverage not only to withstand challenging market environments but also to have the resources to take advantage of underwriting opportunities as they arise. We prefer to deploy our capital in our underwriting businesses. When we cannot find enough underwriting opportunities and have excess capital not needed in the business, we look to return it to its rightful owners, the Company’s shareholders, mainly through share repurchases which increase per-share earnings over the long term. We are prudent in our repurchase decisions, especially when the Company’s shares trade in the market at a premium to book value, as they have in recent years. Our objective is to earn back the premium over a reasonable period based on the Company’s anticipated ROE. In the current market environment, we repurchase shares only when we can expect to earn back the premium within about three years. In 2015, we repurchased 5.9 million Arch common shares at an average price of $61.41, or a total of $365.4 million.

Compensation Objectives and Philosophy

The objectives of our executive compensation program are to:


•	attract and retain quality executives who will contribute to our long-term success and, thereby, increase shareholder value;


•	enhance the individual executive’s short and long-term performance;


•	align the interests of the executive with those of our shareholders; and


•	improve overall Company performance and support the ACGL culture of teamwork, underwriting discipline and commitment to the highest ethical standards.

ACGL seeks to provide a compensation program that is driven by our overall financial performance, the increase in shareholder value, the success of the operating unit or function directly affected by the executive’s performance and the individual performance of the executive. The main principles of this strategy include the following: (1) compensation decisions are driven by performance, (2) increased compensation is earned through an employee’s increased contribution and (3) a majority of total compensation should consist of variable, performance-based compensation.

We believe that the Company’s compensation program provides a competitive mix of pay elements that align executive incentives with shareholder value. Our executive compensation program includes both fixed and variable compensation, with an emphasis on long-term compensation that is tied to Company performance. Although we do not apply rigid apportionment goals in our compensation decisions, our philosophy is that variable pay, in the form of annual cash incentive bonuses and share-based awards, should constitute the majority of total direct compensation. A substantial component of variable compensation is granted in the form of share-based awards, which make stock price appreciation fundamental in realizing a compensation benefit. By emphasizing long-term performance through using long-term incentives, we align our executives’ interests with our shareholders’ interests and create a strong retention tool.

We rely on the Committee's judgment in making compensation decisions for the named executive officers after reviewing the overall performance of our Company and evaluating an executive's performance during the year against established objectives, leadership qualities, scope of responsibilities and current compensation.

Elements of Compensation Program

The four primary components of our executive compensation program are (1) base salary, (2) annual cash incentive bonuses, (3) long-term incentive share-based awards and (4) benefits.

Base Salary. Base salaries are designed to provide competitive levels of compensation to executives based upon their experience, duties and scope of responsibility. We pay base salaries because they provide a basic level of compensation and are necessary to recruit and retain executives. The Committee has the ability, subject to the terms of any employment agreement, to use base salary adjustments to reflect an individual’s performance or changed responsibilities.

Base salary levels are also important because we generally tie the target amount of incentive compensation to an executive’s base salary. For example, annual target bonus opportunities are denominated as a percentage of the executive’s base salary. In addition, as discussed above, the Committee emphasizes a mix of compensation weighted towards variable, performance-based compensation. At lower executive levels, base salaries represent a larger proportion of total compensation than at senior executive levels.

Annual Cash Incentive Bonuses. We use annual cash incentive bonuses as a short-term incentive to drive achievement of our annual performance goals. Specifically, annual cash incentive bonuses are designed to: (1) promote the achievement of financial goals, (2) support our strategic objectives and (3) reward achievement of specific performance objectives.

Annual bonus awards are designed to provide competitive levels of compensation to executives based upon their experience, duties and scope of responsibilities. The size of an executive’s bonus award is influenced by these factors, corporate performance, individual performance and market practice. As an employee’s responsibilities increase, the portion of his or her bonus that is dependent on corporate performance increases.

We initially denominate a target annual cash incentive bonus opportunity as a percentage of an executive’s base salary. For each employee, his or her target is an approximation of the bonus payment that may be paid if performance

Table of Contents

goals and other expectations are attained by both the employee and the Company as a whole. For each of the named executive officers, the target annual bonus opportunity is 100% of such executive’s respective base salary.

Our annual bonus awards are paid under our Incentive Compensation Plan. The plan combines two sets of performance measures: (1) a qualitative judgment about progress and performance each year (referred to as the “Target Bonus Approach”) and (2) a quantitative, formula-based measure (referred to as the “Formula Approach”).

The Target Bonus Approach is applied to all the named executive officers, as well as to our investment management team, substantially all of the employees of Arch Capital Services Inc. and other designated officers of the group. Under the Target Bonus Approach, the executive’s bonus is determined by the Committee taking into account overall Company performance, department or function performance, individual performance and other measures deemed applicable by the Committee. Approved annual bonus awards are paid in cash in an amount reviewed and approved by the Committee and ordinarily paid in a single installment in the first quarter following the completion of a given year.

The Formula Approach is applied to executives included in our insurance, reinsurance and mortgage groups and is reviewed in connection with compensation decisions relating to our named executive officers. Under the Formula Approach, a bonus pool is established for each of our insurance, reinsurance and mortgage segments based on underwriting performance during a given underwriting year. For each underwriting year, the bonus pool will be recalculated annually as actual underwriting results emerge, and any resultant payments will be made to the participants over a 10-year development period. Since much of our business requires multiple years to determine whether we have been successful in our assessment of risk, we have structured our plan in this manner so that incentive payments are made to employees over a period of years as actual results become known, which we believe effectively aligns pay with performance.

Please refer to “ 2015 Compensation Decisions.”

Long-Term Incentive Share-Based Awards. We emphasize long-term variable compensation at the senior executive levels because of our desire to reward effective long-term management decision making and to provide the named executive officers with a future interest in the Company. Long-term incentives, which comprise a significant portion of executive compensation, are designed to focus attention on long-range objectives and future returns to shareholders, and are delivered to the named executive officers and other employees through share-based awards under our long-term incentive plans. Our long-term incentive share award plans provide for the grant to eligible employees of a wide range of share-based awards.

The Company provides grants in the form of restricted common share/unit awards, stock options and SARs. SARs represent a right to be paid, upon exercise, an amount measured by the difference between the fair market value per share on the exercise date and the exercise price of the SAR (the “spread”), multiplied by the number of shares with respect to which the SAR is exercised, with the resultant amount paid in shares valued on the exercise date. The value of SARs to employees should be equivalent to that of options. In addition, the Company’s stock option agreements allow for net exercise to the extent permitted or otherwise advisable under applicable legal and accounting principles.

As indicated above, the Company’s mix of share-based awards includes restricted shares and units, which are a more predictable and flexible equity incentive than option and SAR awards. As a result, restricted shares and units are generally more meaningful to employees and, therefore, could provide a more significant incentive to remain with the Company during the vesting period.

Our share-based compensation is designed to align the interests of executives and shareholders by providing value to the executive as the share price increases. Due to the variability of the share price, the value of stock options, SARs and restricted share/unit awards is dependent upon our overall results and how we are perceived by our shareholders and the marketplace. Based on the foregoing, the Company believes that share-based awards encourage executives and other employees to focus on behaviors and initiatives that should lead to an increase in the price of our common shares, which benefits all ACGL shareholders.

Share-based compensation grant levels and awards are reviewed and determined by the Committee periodically. Grants of share-based compensation are determined on the basis of a number of factors, including: (1) corporate performance on an absolute basis and relative to Selected Competitors and individual performance, (2) the executives’ contribution to the Company’s success and (3) competitive total compensation and long-term incentive grant levels as determined in the market.

Table of Contents

Share-based awards granted to employees vest over a prescribed period, motivating executives to remain with us and sustain high corporate performance in order to increase the value of such awards. The annual grants of share-based awards outlined in the “Grants of Plan-Based Awards” table that were made in May 2015 will vest ratably over a three-year period. The Company believes that these annual grants are consistent with the Company’s objectives to retain management and to align further the interests of management and the Company’s shareholders. Options and SARs awarded to employees are granted with an exercise price equal to the closing price of the shares on the date of grant and, subject to earlier termination under certain circumstances as set forth in the award agreements, will expire 10 years from the grant date.

Please refer to “ 2015 Compensation Decisions.”

The current annual award agreements for the named executive officers provide that, in the event that the employee's employment is terminated by the Company other than for cause or by the employee for good reason within two years following a change in control, unvested shares and unvested options/SARs would immediately vest, and the options/SARs would have a remaining term of 90 days from termination. Unlike single trigger provisions that provide for vesting immediately upon a change in control, the agreements require a double trigger, i.e., the consummation of a change in control followed by an involuntary loss of employment or termination following an involuntary change in responsibilities within two years thereafter. This is consistent with the purpose of the provision, which is to provide employees with a level of financial protection upon loss of employment following a change in control.

In addition, our annual share-based award agreements provide that, if an employee's employment terminates (other than for cause) after retirement age, unvested shares and unvested options would continue to vest pursuant to the normal vesting schedule so long as the employee does not engage in a competitive activity following retirement. However, the award agreements also provide that, if a retired employee does engage in a competitive activity, any unvested awards would be forfeited and the holder would have a reduced period in which to exercise vested options. These provisions provide additional alignment with shareholders for long-term decision making by executives nearing retirement and are designed to help provide our retired employees with financial security so long as the Company's interests are protected.

Please refer to the description of our award agreements included below under the caption “Share-Based Award Agreements.”

Benefits. ACGL seeks to provide benefit plans, such as medical coverage and life and disability insurance, consistent with applicable market conditions. Our health and welfare plans help ensure that the Company has a productive and focused workforce through reliable and competitive healthcare and other benefits. Defined contribution retirement plans are provided for all employees according to local market conditions. Retirement plans help employees save and prepare for retirement. The named executive officers are eligible for the benefit plans provided to all other employees. The Company generally credits only actual service with the Company towards benefits under the Company’s benefit plans. The Company does not maintain any defined benefit retirement or pension plans.

During 2015 , certain members of senior management, including Mr. McElroy, participated in the Company’s non-qualified defined contribution retirement plan, which provides additional retirement savings opportunities that cannot be achieved with tax-qualified plans due to limits on annual compensation. Participants in the non-qualified plan do not receive preferential earnings on their investments. Account balances are paid in cash following termination of employment in accordance with the terms of the plan. The principal benefit to the participating executives is that U.S. taxes are deferred until distribution of the funds. As described below under “—Tax Considerations—Sections 409A and 457A,” commencing with the 2009 year, this benefit is no longer available to certain employees, including Messrs. Iordanou, Lyons and Grandisson, due to changes in the governing law. In lieu of pension and matching contributions previously provided to these former participants through the non-qualified plan, we provide comparable benefits to these employees in the form of current cash payments subject to tax.

The Company maintains a broad-based employee share purchase plan. The purpose of this plan is to provide employees with an opportunity to purchase common shares of ACGL through payroll deductions, thereby encouraging employees to share in the economic growth and success of the Company. The Company also provides a broad-based matching gift program pursuant to which the Company matches eligible contributions by employees to qualified charitable organizations. During 2015 , the Company made an aggregate of approximately $477,992 in matching contributions on behalf of the named executive officers.

In addition, the Company provides our named executive officers with perquisites and other benefits that the Company and the Committee believe are reasonable and consistent with its overall compensation program to better enable the Company to attract and retain key employees. In developing our guidelines for the administration of these various benefits,

Table of Contents

the Company reviews the job requirements of various positions and the anticipated business use of such benefits, as well as available market data. Similar benefits are generally provided by insurers and reinsurers for similarly situated employees and we believe these benefits are necessary for recruitment and retention purposes. These benefits primarily relate to those executives who work and reside in Bermuda and are typical of such benefits provided to expatriates located in Bermuda. Examples of these benefits include housing allowances, club memberships, the cost of tax preparation services and home leave for executives and family for those executives working outside their home country. In addition, certain tax regulations often subject our executives to taxation on the receipt of certain of these benefits. In certain of these situations, particularly in the case of those executives receiving expatriate benefits while working outside their home country, we provide an additional payment to the executive to reimburse the executive for approximate amounts of additional tax liability the executive will need to pay as a result of receiving such benefits.

Relationship Between Compensation Policies and Risk Management

We believe our approach to evaluation of performance and the design of our compensation programs assists in mitigating excessive risk-taking that could harm our Company. We emphasize long-term compensation that is tied to Company performance. Furthermore, the Formula Approach included in our Incentive Compensation Plan, which is applied to employees in our insurance, reinsurance and mortgage groups, is based on underwriting performance during a given underwriting year. For each underwriting year, the bonus pool will be recalculated annually as actual underwriting results emerge, and any resultant payments will be made to the participants over a 10-year development period. Since much of our business requires multiple years to determine whether we have been successful in our assessment of risk, we have structured our plan in this manner so that incentive payments are made to employees as actual results become known, which effectively aligns pay with performance. In addition, a substantial component of variable compensation is granted in the form of multi-year vesting share-based awards, which make stock price appreciation over an extended period of time fundamental in realizing a compensation benefit.

The Company’s compensation philosophy and related governance features are also complemented by several specific elements that are designed to align our compensation with long-term shareholder interests. These elements include a clawback policy covering all executive officers, including the chief executive officer, which provides for affected incentive-based compensation to be recouped by the Company in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws. In an effort to further align the interests of the senior management team and the directors with the interests of shareholders, the Company has share ownership guidelines and share holding requirements that together require our senior executives and the directors to maintain designated levels of ownership of the common shares of ACGL. In addition, under the insider trading policy included in our Code of Business Conduct, our named executive officers, other members of senior management and our directors are not permitted to engage in hedging activities with respect to the Company’s securities.

Employment Agreements

The Company has entered into employment agreements with its chief executive officer and each of its other named executive officers. The employment agreements with our named executive officers require an involuntary or constructive termination of the executive’s employment (“double trigger”) in order for severance payments to be made. The terms of the employment agreements, including the severance benefit provisions, were structured to attract and retain persons believed to be key to our success, as well as to be competitive with compensation practices for executives in similar positions at companies of similar size and complexity. Please refer to “Employment Arrangements” below for a description of our employment agreements with Messrs. Iordanou, Lyons, Grandisson, McElroy and Hutchings.

Clawback Policy

The Company has a clawback policy covering all executive officers, including the chief executive officer. This policy provides that, in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, the Committee will review all incentive-based compensation that was paid to current or former executive officers during the three-year period preceding the required restatement. If any such incentive-based compensation would have been lower as a result of the restated financial results, the Committee will require the reimbursement of the incremental portion of the incentive-based compensation in excess of the compensation that would have been paid based on the restated financial results (to the extent permitted by applicable law). This policy will be interpreted in accordance with the applicable rules of NASDAQ (or other securities exchange on which our common shares are listed from time to time).

Matters Relating to Share Ownership and Share-Based Compensation

Share Ownership Guidelines. In an effort to further align the interests of the senior management team with the interests of shareholders, the Company has share ownership guidelines that require these executives to maintain designated levels of ownership of the common shares of ACGL. Specifically, these guidelines require common share ownership levels as follows: (1) chief executive officer of ACGL—six times base salary; (2) named executive officers and other executives who file reports under Section 16 of the Exchange Act and certain other members of senior management designated from time to time—four times base salary; and (3) other designated members of senior operating management—three times base salary. Each executive has five years to comply with the guidelines, and stock options, SARs and unvested restricted shares/units do not count toward the requirement.

Share Holding Requirements for Executives. In an effort to ensure each of our senior executives meet and maintain their share ownership pursuant to our guidelines, the company requires they retain an amount equal to 50% of the net profit shares received from Company equity awards until he or she meets their target ownership levels. Net profit shares are the shares remaining after payment of the exercise price of an option and taxes owed on exercise of options or SARs, vesting of restricted stock, or vesting and payout under restricted stock units and performance shares. See also “Director Compensation” for a description of share retention guidelines that require our non-employee directors to maintain designated levels of ownership of common shares of ACGL.

No Hedging Permitted. Under the insider trading policy included in our Code of Business Conduct, our named executive officers, other members of senior management and our directors are not permitted to engage in hedging activities with respect to the Company’s securities. Specifically, these insiders may not engage in short sales, purchases on margin or buying or selling put options or call options with respect to our securities.

Options and SARs. Our plans do not permit granting of stock options or SARs at an exercise price below the closing price on the grant date and also do not allow for repricing or reducing the exercise price of a stock option or SAR. We also do not allow out-of-the-money options or SARs to be exchanged for cash or other property. We set the exercise price of stock options and SARs at the closing share price on the date of grant.

Certain Procedures Regarding Share-Based Compensation. The Committee approves all grants of share-based compensation to the named executive officers and other executives who file Section 16 reports with the SEC, and these awards also are generally approved by the full Board of Directors. The Committee approves annual share-based awards to other employees or, alternatively, may approve the size of the pool of such annual share-based awards to be granted to other employees, but may delegate to the chief executive officer and other members of senior management the authority to make and approve specific awards to other employees. In addition, the Committee has delegated to the chief executive officer or, in his absence, the chief financial officer, the authority to make and approve specific share-based awards to non-executives, principally new hires, who are not subject to Section 16 of the Exchange Act. The Committee reviews any grants made under this delegation on a regular basis.

Our practice is to make annual grants of share-based compensation on the dates of regularly scheduled meetings of the full Board of Directors. Our process for establishing the grant date well in advance provides assurance that grant timing is not being manipulated for employee gain. It is our current intention to consider the determinations for annual grants on the date of the May meeting of our Board of Directors. Under our current practice, we have chosen the May meeting of our Board of Directors because we believe that more complete information will be publicly available at that time regarding the financial performance of our Selected Competitors and the related share-based awards granted by these companies for performance during the prior year, which will provide the Committee and the Board of Directors with additional useful data before making final determinations on share-based compensation. Generally, awards are granted to the named executive officers as part of the annual process, which encompassed 706 Company employees worldwide for awards granted in 2015 for 2014 performance. We may grant a small percentage of awards at other times throughout the year on the date of regularly scheduled meetings of the Committee or the full Board of Directors in connection with hiring or the promotion of an executive or special retention circumstances. In addition, pursuant to the delegation of authority by the Committee, the chief executive officer or, in his absence, the chief financial officer, may approve at other times grants of share-based awards to non-executive officers. In the case of a new hire, the awards have grant dates corresponding to the date the employment commences for the new hire.

Tax Considerations

No Excise Tax Gross-Ups. The Company does not provide excise tax gross-up payments to any of its executives.

Table of Contents

Section 162(m). Section 162(m) of the Code generally limits the deductible amount of annual compensation paid to the chief executive officer and three other most highly compensated executive officers (other than the chief financial officer) to no more than $1,000,000 each. Since ACGL will not generally be subject to United States income tax, the limitation on deductibility will not directly apply to it. However, the limitation would apply to a United States subsidiary of ACGL if it employs the chief executive officer or one of the three other most highly compensated executive officers (other than the chief financial officer). Qualified performance-based compensation will be excluded from the $1,000,000 limitation on deductibility. Our policy is to qualify, to the extent consistent with our compensation goals and programs, our executive officers’ compensation for deductibility under applicable tax laws. Consistent with this policy, our Incentive Compensation Plan includes a provision pursuant to which payments under the plan may be deferred if it is necessary in order to avoid nondeductibility of the payments under Section 162(m) of the Code. However, the Committee believes that its primary responsibility is to provide a compensation program that will attract, retain and reward the executive talent necessary to our success. Consequently, the Committee recognizes that the loss of a tax deduction could be necessary in some circumstances due to the restrictions of Section 162(m). The Committee will review tax consequences as well as other relevant considerations in connection with compensation decisions.

Sections 409A and 457A. Section 409A of the Code, which governs deferred compensation arrangements, generally provides that distributions of deferred compensation to our senior officers as a consequence of termination of employment may not be made sooner than six months after termination. Section 409A also made changes to a number of other areas, including the timing of elections and distributions with respect to deferred compensation. In late 2008, the Emergency Economic Stabilization Act added Section 457A of the Code. While Section 409A provides certain rules that must be complied with if deferred compensation arrangements are utilized, Section 457A generally prohibits U.S. taxpayers from deferring U.S. income tax on compensation attributable to services performed after December 31, 2008 for certain employers, including Bermuda-based employers such as ACGL and Arch Re (Bermuda). As a result, for periods on or after January 1, 2009, certain employees of ACGL and Arch Re (Bermuda), including Messrs. Iordanou, Lyons and Grandisson, are no longer permitted to participate in the non-qualified defined contribution retirement plan. As required by Section 457A, the non-qualified plan provides that compensation that has been previously deferred by these employees will be distributed on or before December 31, 2017, with the exception of Mr. Lyons. In lieu of pension and matching contributions previously provided to these former participants through the non-qualified plan, we provide comparable benefits to these participants in the form of current cash payments subject to taxation. In addition, in light of Section 457A, and in an effort to maintain comparable benefits for all employees, the Company has provided certain of its Bermuda-based employees who are U.S. taxpayers with the opportunity to receive a portion of their annual incentive bonus in the form of SARs or restricted shares. There is no matching or additional Company contributions associated with this election and, as a result, the Company will not incur any additional expense by providing this benefit.

Committee Review

The Committee reviews the performance of, and approves the compensation paid to, the chief executive officer and the other named executive officers. The chief executive officer assists in the reviews of the named executive officers other than himself through making recommendations on goals and objectives, evaluating performance and making recommendations regarding compensation. With this input from the chief executive officer with respect to the other named executive officers, the Committee uses its judgment in determining compensation for these officers.

The Committee meets in executive sessions (without management present) as necessary, particularly when administering any aspect of the compensation program for the chairman and chief executive officer of ACGL. Compensation matters in respect of the chairman and chief executive officer of ACGL, the chief financial officer of ACGL and the general counsel of Arch Capital Services Inc. are subject to ratification by the Board of Directors.

In determining the amount of named executive officer compensation each year, the Committee reviews overall corporate performance, the performance of the business unit or function that the executive leads and an assessment of each executive’s performance. In connection with establishing levels of base salary, annual incentives, long-term incentives and benefits, the Committee reviews information compiled from annual reports on Form 10-K, proxy statements and other publicly available information for a representative sample of publicly-traded insurers and reinsurers which we believe compete directly with us for executive talent (the “Selected Competitors”). Many of these Selected Competitors are of generally similar size and have generally similar numbers of employees, product offerings and geographic scope.

For 2015 , the Selected Competitors are: Chubb Limited (formerly known as ACE Limited), Allied World Assurance Company Holdings, AXIS Capital Holdings Limited, Endurance Specialty Holdings Ltd., Everest Re Group, Ltd., PartnerRe Ltd., RenaissanceRe Holdings Ltd., Validus Holdings Ltd., W.R. Berkley Corporation and XL Group plc.

2015 Compensation Decisions

The specific annual bonus and long term incentive compensation decisions made for each named executive officer for 2015 reflect the performance of the Company against key financial and operational measures as well as the achievement of strategic objectives described above under “Executive Summary.” In 2015, we allocated compensation for our named executive officers as follows: (1) base salaries ranging from approximately 10% to 27% of total compensation and (2) variable, performance-based compensation, in the form of annual cash incentive bonuses and long-term incentive share-based awards, ranging from approximately 73% to 90% of total compensation, as described below. The variable performance-based compensation component of our chief executive officer’s total compensation was 90% . In addition, our chief executive officer elected to receive 100% of his cash bonus for 2015 in the form of stock options, with an exercise price equal to the closing stock price on the grant date. Share price appreciation over an extended period of time will be required in order for Mr. Iordanou to realize any compensation benefit from this significant component of his 2015 compensation.

Consistent with our philosophy of emphasizing variable, performance-based compensation, we did not increase the base salaries of our named executive officers, except that during 2015 Mr. Hutchings’ base salary was increased to reflect market comparison data.

In determining the performance-based compensation of our chief executive officer and other named executive officers, in addition to taking into account the performance of the Company described under “Executive Summary,” the Committee reviewed the estimated bonus pool determined under the Formula Approach included in our Incentive Compensation Plan. Under the Formula Approach, a bonus pool is established for each of our insurance, reinsurance and mortgage segments based on underwriting performance during a given underwriting year. These calculations are based on ROE targets for the current and prior underwriting years. For each underwriting year, the bonus pool will be recalculated annually as actual underwriting results emerge, and any resultant payments will be made to the participants over a 10-year development period. Since much of our business requires multiple years to determine whether we have been successful in our assessment of risk, we have structured our plan in this manner so that incentive payments are made to employees over a period of years as actual results become known, which we believe effectively aligns pay with performance.

W ith respect to the performance-based portion of Mr. Iordanou’s compensation, in addition to its review of the calculations under the Formula Approach described above, the Committee also evaluated Mr. Iordanou’s contributions toward creation and enhancement of shareholder value by considering the performance of the Company and a number of other factors, including the Company’s financial results and strategic initiatives achieved under his leadership over the near and long-term, with a focus on long-term performance and creation of shareholder value.

The Committee focused on the fact that the Company has a disciplined approach to underwriting, investment management and capital management. Our diversification across three business segments is another important factor, allowing us to seek out the best underwriting opportunities; and our underwriting philosophy of generating adequate risk-adjusted returns on capital, not on maximizing premiums written. In addition, the Committee recognized we have made good progress continuing to build our mortgage segment, which helps diversify the Company’s revenue and earnings streams. The Committee recognized the challenging economic and operating environment and that the Company’s diversified platform and its collaborative culture of performance, accountability, teamwork and ethical conduct allowed the Company to meet these challenges and remain financially strong.

In determining the amount and mix of compensation elements, the Committee employs its business judgment in administering the Company’s compensation programs and in the evaluation process, which the Committee believe s enables the Company to adapt more quickly to changes in the business environment, take advantage of opportunities available in the marketplace and pursue strategic initiatives over the longer term. We believe our approach to evaluation of performance and the design of our compensation programs assists in mitigating excessive risk-taking that could harm our Company.

In light of the Committee’s assessment, and as a result of his performance, Mr. Iordanou received a bonus of $4,050,000 for 2015 , a 10% decrease from 2014. The alignment of interests between the shareholders and Mr. Iordanou are further strengthened due to the fact that, as the Committee was aware, Mr. Iordanou had elected to receive 100% of his annual bonus in the form of at-the-money stock options instead of cash. Under an election program offered by the Company, Mr. Iordanou received 100% of his bonus in the form of stock options on terms provided under the election, namely, 244,750 fully vested stock options exercisable for a 10-year period. The per share exercise price is $68.20 , which was the closing price on the date of grant, and the stock option award was valued in the same manner as valued for

Table of Contents

financial reporting purposes. Share price appreciation over an extended period of time will be required in order for Mr. Iordanou to realize any compensation benefit from this significant component of his 2015 compensation.

In May 2015 , for his performance in 2014 , Mr. Iordanou also was granted long-term incentive awards in the form of 58,110 restricted common shares and 58,110 stock options with a per share exercise price of $ 62.51 , each of which will vest in three equal annual installments commencing on the first anniversary of the grant date. These awards, which are reflected in the “Summary Compensation Table,” were awarded based on an assessment of Mr. Iordanou’s performance during 2014 . As noted above, the Committee expects to consider determinations for share-based compensation for 2015 performance at meetings scheduled to be held in May 2016 .

In determining the performance-based compensation of our other named executive officers, the Committee evaluated the overall performance of the Company and their contributions to that performance, as well as the performance of the business or function that each named executive officer leads. The Committee did not apply a formula or assign performance measures relative weights but made a determination after considering these measures collectively.

With respect to Mr. Lyons, the Committee reviewed his key roles in financial reporting, enterprise risk management, regulatory matters and capital management. In addition, the Committee considered that the other aspects of the financial function for the Company, which involved, among other things, investor relations and ratings agency matters, performed well under Mr. Lyons’ leadership.

In determining the performance-based compensation of Messrs. Grandisson and McElroy, who during 2015 managed the Company’s reinsurance and mortgage operations and insurance operations, respectively, the Committee reviewed the profitability of the reinsurance group and mortgage group and the insurance group, including their respective groups’ effectiveness in managing the underwriting cycle. As part of that analysis, the Committee reviewed the estimated bonus pool determined under the Formula Approach for the 2015 and prior underwriting years, which is based on various ROE targets and will be recalculated annually over a 10-year development period as actual results emerge, which effectively aligns pay with performance.

The Committee also reviewed Mr. Grandisson’s and Mr. McElroy’s oversight of key operational matters for their respective groups, including those relating to overall management, including expense management, risk management and infrastructure. In addition, the Committee considered their focus on underwriting discipline and the Company’s pursuit of strategic initiatives which, for Mr. Grandisson included the continued expansion of the Company’s mortgage capabilities globally, and their focus on business opportunities in specialty niches under their leadership, which we believe will achieve acceptable ROE targets over the cycle.

In determining the performance-based portion of Mr. Hutchings’ compensation, the Committee reviewed the performance of the Company’s internal and external investment portfolios and Mr. Hutchings’ oversight of the investment portfolio under the challenging investment environment in 2015 of continuing low yields and market volatility. The Committee considered our emphasis on total investment return, which contributes to increases in book value per share and our strategy of allocating a portion of our portfolio to equities and alternative investments, which provides diversification and offers the potential for higher returns. In addition, the Committee reviewed a number of other factors, including Mr. Hutchings’ role in increasing the staffing and expanding the capabilities of the Company’s internal investment function.

In light of these assessments, the named executive officers received the following annual incentive cash bonuses for performance during 2015 : Mr. Lyons- $1,080,000 ; Mr. Grandisson- $2,250,000 ; Mr. McElroy- $1,000,000 ; and Mr. Hutchings- $675,000 . In addition, in May 2015 , these named executive officers were granted the following long-term incentive share-based awards (with the same principal terms included in Mr. Iordanou’s May 2015 grants, as described above): Mr. Lyons- 10,180 stock options and 10,180 restricted common shares; Mr. Grandisson- 14,630 stock options and 14,630 restricted common shares; Mr. McElroy- 9,220 stock options and 9,220 restricted common share units; and Mr. Hutchings- 9,220 stock options and 9,220 restricted common shares. These share-based awards, which are reflected in the “Summary Compensation Table,” were awarded following an assessment of the executives’ performance during 2014 . As noted above, the Committee expects to consider determinations for share-based compensation for 2015 performance at meetings scheduled to be held in May 2016 .

The amounts shown in these columns represent the aggregate grant date fair value of awards computed in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718 Compensation—Stock Compensation, excluding the effect of forfeitures. We have computed the estimated grant date fair values of share-based compensation related to stock options using the Black-Scholes option valuation model having applied the assumptions set forth in the notes accompanying our financial statements. See note 19 , “Share-Based Compensation,” of the notes accompanying our consolidated financial statements included in our 2015 Annual Report. These grants were made in May of the year for which they are reported and were based on performance for the prior year, e.g., the 2015 awards were based on 2014 performance.

Such restricted share awards shown in the above table were granted in the form of restricted common shares, except for Mr. McElroy’s award, which was granted in the form of restricted common share units that will be settled in common shares after the termination of his employment as provided in the award agreement.


(2)	The amounts shown in this column represent the grant date fair value of the underlying award computed in accordance with accounting guidance governing share-based compensation arrangements as discussed in note 19 , “Share-Based Compensation,” of the notes accompanying our consolidated financial statements included in our 2015 Annual Report.

Table of Contents

The Company maintains an Executive Supplemental Non-Qualified Savings and Retirement Plan. Under this plan, participants may defer eligible base salary in excess of the compensation limit imposed by the Code (“Excess Compensation”) (for 2015 , base salary in excess of $265,000) and, with respect to the eligible named executive officers, the Company provides matching contributions on these deferrals in amounts equal to 100% of the first 3% of salary contributed to the plan and 50% of the next 3% of salary contributed to the plan. The Company also makes pension-like contributions on behalf of the eligible named executive officers in an amount equal to 10% of Excess Compensation. In addition, the named executive officers may defer up to 100% of annual bonus paid each year and these bonus deferral contributions are not eligible for matching contributions by the Company. Until distribution, the contributions and any earnings are held in an irrevocable trust known as a “rabbi trust” by an independent trustee, and the trust assets remain subject to the Company’s creditors. The participants may elect to have their contributions under the plan deemed to be invested among certain permissible mutual fund options. The plan provides that, as soon as practicable following retirement, death or other termination of employment, but subject to any delay required by the Code, all benefits under the plan will be distributed either in a single lump sum in cash or, if elected, in installments over a period not to exceed 10 years.

As indicated above, Section 457A of the Code generally prohibits U.S. taxpayers from deferring U.S. income tax on compensation attributable to services performed after December 31, 2008 for certain employers, including Bermuda-based employers such as ACGL and Arch Re (Bermuda). As a result, for periods on or after January 1, 2009, certain employees of ACGL and Arch Re (Bermuda), including Messrs. Iordanou, Lyons and Grandisson are no longer permitted to participate in the non-qualified defined contribution retirement plan. In addition, and as required by Section 457A, the non-qualified plan provides that compensation that has been previously deferred by these employees other than Mr. Lyons will be distributed on or before December 31, 2017. In lieu of pension and matching contributions previously provided to these former participants through the non-qualified plan, we have provided comparable benefits to these participants in the form of current cash payments, subject to tax. Such cash payments have been included in the “Summary Compensation Table” in the “All Other Compensation” column for fiscal years 2015 , 2014 and 2013 .

Employment Arrangements

Set forth below is a summary of the material terms of the employment arrangements with each of the named executive officers.

Constantine Iordanou

ACGL and Constantine Iordanou entered into an employment agreement, as amended, pursuant to which Mr. Iordanou agreed to serve as ACGL’s Chief Executive Officer for a term that will end on March 31, 2018.

Mr. Iordanou’s employment agreement provides for an annual base salary of $1,000,000 , which has remained unchanged since 2002 and is subject to review annually for increase at the discretion of the Board of Directors. Mr. Iordanou is eligible to participate in an annual bonus plan on terms established from time to time. The target rate for the annual cash bonus is 100% of his annual base salary. Mr. Iordanou is also entitled to participate in employee benefits programs such as major medical, life insurance and disability insurance; the cost of preparation of annual tax returns and associated tax planning on a basis no less favorable than such arrangements provided to similarly situated senior executives residing in Bermuda; and other fringe benefits customarily provided to similarly situated senior executives residing in Bermuda, which includes housing expense reimbursement, payroll tax reimbursements and automobile allowance. Since Mr. Iordanou previously relocated to Bermuda, his employment agreement also provides for the use of any private aircraft owned or leased by the Company or such other reasonably comparable air transportation for travel between Bermuda and the United States. In addition, Mr. Iordanou is entitled to an amount equal to the excess, if any, of the amount of income and employment taxes payable by him to Bermuda and any other governmental taxing authority for the applicable taxable year over the amount that would have been payable by him had he resided for the entire taxable year in the State of the United States with respect to which he files a state income tax return as a resident for the year. The intent of this provision is that ACGL will reimburse Mr. Iordanou for additional taxes imposed on him arising from his working and residing in Bermuda as described in footnote 3 in the “Summary Compensation Table.” The agreement also provides that, during the employment period, ACGL will use its best efforts to cause Mr. Iordanou to be elected to our Board of Directors.

The agreement provides that if Mr. Iordanou’s employment is terminated due to his death, his estate will receive a prorated portion of his bonus that would have been paid for the year of his death and an amount equal to two times the sum of his base salary and target annual bonus payable in a lump sum, but offset by life insurance proceeds received by his estate from coverage provided by the Company. His agreement also provides that if his employment is terminated due to

Table of Contents

his permanent disability, he will receive a prorated portion of his bonus that would have been paid for the year in which he becomes disabled, as determined by the Board of Directors. The agreement further provides that if we terminate Mr. Iordanou’s employment without cause or he resigns for good reason, he will receive a prorated portion of his bonus that would have been paid for the year of his termination and an amount equal to two times the sum of his base salary and target annual bonus payable in 18 equal installments, the first nine of which will be paid monthly over nine months and the last nine of which will be paid in a lump sum on the nine-month anniversary of termination (subject to six month deferral as required under Section 409A of the Code). Mr. Iordanou’s and his spouse’s major medical insurance coverage benefits pursuant to his employment agreement will continue for 18 months after the date of termination in the event that (1) his employment ends due to death or permanent disability, (2) he is terminated other than for cause, (3) he resigns for good reason (or until such time as he has major medical insurance coverage under the plan of another employer) or (4) his employment ends due to the expiration of the term on March 31, 2018. The agreement also provides that if Mr. Iordanou’s employment is terminated by us for cause or he resigns other than for good reason, he will receive his base salary through the date of termination.

Mr. Iordanou has agreed that, during the employment period and for the period of 18 months after termination of employment, he will not compete with the businesses of ACGL or any of its subsidiaries as such businesses exist as of the date of termination, within any geographical area in which ACGL or any of its subsidiaries engage in such businesses. If we terminate Mr. Iordanou’s employment without cause or he terminates for good reason, the term of his non-competition period will extend only as long as he is receiving severance benefits provided for under his employment agreement under such circumstances. However, in the event of termination due to expiration of the term of the agreement on March 31, 2018 or by reason of Mr. Iordanou’s resignation other than for good reason, the non-competition period will continue beyond his termination date for up to 18 months only if the Company so elects and (1) pays Mr. Iordanou an amount equal to two times the sum of his annual base salary and target annual bonus (prorated for the period selected by the Company) in 18 equal installments, the first 12 of which will be paid monthly and continuing monthly thereafter through the month that includes the first anniversary of the separation from service and the last six of which will be paid on the first anniversary of the separation from service (subject to six month deferral as required under Section 409A of the Code); and (2) provides medical benefits for the selected period. Mr. Iordanou also agreed that he will not, for an 18-month period following his date of termination, induce or attempt to induce any of our employees to leave his or her position with us or induce any customer to cease doing business with us.

In addition, in the event of a change in control, the agreement provides that any payments contingent on a change of control that would be subject to the excise tax imposed by Section 4999 of the Code will be reduced by an amount equal to the smallest amount possible such that no payment would be subject to such excise tax; provided that if, without any reduction in payments, the net amount retained by Mr. Iordanou, after subtracting from the payments otherwise to be made all taxes imposed thereon, would exceed the after-tax amount that would be retained by him after the reduction described above, then no reduction in payments will be made. In no event will Mr. Iordanou receive a gross-up payment for excise taxes payable under Section 4999 of the Code. The agreement also provides for indemnification of Mr. Iordanou to the fullest extent permitted by applicable law and the Company’s governing instruments in connection with suits or proceedings arising by reason of the fact that he is or was a director, officer or employee of the Company. The Company has also agreed to pay reasonable legal fees incurred by Mr. Iordanou as result of any dispute or contest with the Company regarding the agreement, unless the Company substantially prevails on all material causes of action in the dispute or contest.

Mark D. Lyons

ACGL and Mr. Lyons entered into an employment agreement with a term extending through September 1, 2016. The agreement will be automatically extended for additional one-year periods, unless we or Mr. Lyons gives notice at least 180 days prior to the expiration of the original term or any extended term. The agreement provides for a specified annual base salary, and the target rate for the annual cash bonus is 100% of the annual base salary. Mr. Lyons is eligible to receive annual cash bonuses and share-based awards at the discretion of the Board and is also entitled to participate in employee benefits programs such as major medical, life insurance and disability insurance, the cost of preparation of annual tax returns and associated tax planning, and other fringe benefits customarily provided to similarly situated senior executives residing in Bermuda, which includes housing expenses, payroll tax reimbursements and automobile allowance. His agreement also provides that the Company will reimburse him, on an after-tax basis, for his reasonable expenses incurred in traveling between Bermuda and the United States. In addition, Mr. Lyons is entitled to an amount equal to the excess, if any, of the amount of income and employment taxes payable by him to Bermuda, Illinois and any other governmental taxing authority over the amount that would have been payable by him had he resided in Illinois for the entire calendar

Table of Contents

year. The intent of this provision is that ACGL will reimburse Mr. Lyons for additional taxes imposed on him arising from his working and residing in Bermuda as described in footnote (4) in the “Summary Compensation Table.” In addition, upon the termination of his employment for any reason, ACGL will reimburse him for reasonable expenses incurred by him for the cost of relocating his household items to the United States and airfare for Mr. Lyons and his family to return to the United States.

The agreement provides that if Mr. Lyons’ employment is terminated without cause or for good reason, he will be entitled to receive an amount equal to: the greater of (1) 18 months of his base salary and (2) the total remaining base salary for the employment period which would have been paid to him under his employment agreement if the employment period had not been so terminated, payable over 12 months. The agreement also provides that if Mr. Lyons’ employment is terminated for cause, as a result of his resignation or leaving employment other than for good reason, as a result of death or permanent disability, or by written notice of the intention not to renew the agreement by us or Mr. Lyons, he (or his estate) will be entitled to receive his base salary through the date of termination. The agreement further provides that if Mr. Lyons’ employment is terminated by reason of death or permanent disability, he (or his estate) will also be entitled to receive a prorated portion of his target annual bonus (offset by any proceeds received from any insurance coverages provided by the Company), such amount would be paid to him by no later than March 15th of the calendar year following the calendar year of such termination of employment. For such purposes, the annual bonus will not be less than the average annual bonus received for the preceding three years. Mr. Lyons’ major medical insurance coverage benefits pursuant to his employment agreement will continue for 12 months after the date of termination (or until he is provided by another employer with benefits substantially comparable, with no pre-existing condition limitations, to the benefits provided by such plan) in the event that (a) his employment ends due to permanent disability, (b) he is terminated other than for cause or (c) he resigns for good reason.

Mr. Lyons has agreed that, during the employment period and for a period of one year after termination of employment, he will not compete with the businesses of ACGL or any of its subsidiaries as such businesses exist or are in process or being planned as of the date of termination. Mr. Lyons also agreed that he will not, for a period of one year following his date of termination, induce or attempt to induce any of our employees to leave his or her position with us or induce any customer to cease doing business with us.

Marc Grandisson

Under an employment agreement, Marc Grandisson serves as President and Chief Operating Officer of ACGL. The terms of his employment provide for a specified annual base salary. The annual base salary is subject to review annually for increase at the discretion of the Board of Directors. The target rate for the annual cash bonus for Mr. Grandisson is 100% of his annual base salary. Mr. Grandisson is eligible to receive annual cash bonuses and share-based awards at the discretion of our Board of Directors. Mr. Grandisson is also entitled to participate in employee benefits programs such as major medical, life insurance and disability insurance and other fringe benefits customarily provided to similarly situated senior executives residing in Bermuda, which includes housing expenses, payroll tax reimbursements and automobile allowance. His agreement also provides that the Company will reimburse him, on an after-tax basis, for his reasonable expenses incurred in traveling between Bermuda and Canada. The current term of his employment agreement ends on December 31, 2016 , but we or Mr. Grandisson may terminate his employment at any time. The agreement will be automatically extended for additional one-year periods, unless we or Mr. Grandisson gives notice at least 60 days prior to the expiration of the original term or any extended term.

Share-Based Award Agreements

Our long-term incentive share award plans provide for the grant to eligible employees and directors of stock options, SARs, restricted shares, restricted share units payable in common shares or cash, share awards in lieu of cash awards, dividend equivalents, performance shares and performance units and other share-based awards.

To date, the Company has provided grants in the form of stock options, SARs, restricted common shares and restricted common share units. Share-based awards granted to employees vest over a prescribed period, motivating

Table of Contents

executives to remain with us and sustain high corporate performance in order to increase the value of such awards. Our share-based awards typically provide for vesting over three years, and our 2015 Long Term Incentive and Share Award Plan generally requires, at minimum, one year vesting, exercisability and distribution provisions for share-based awards granted under it. Subject to exceptions for death, disability and change in control, our 2015 Long Term Incentive and Share Award Plan prohibits the exercise of discretion to accelerate vesting of awards. The May 2015 annual grants outlined in the “Grants of Plan-Based Awards” table will vest over a three-year period, which the Company believes is consistent with the Company’s objectives to retain management and to align further the interests of management and the Company’s shareholders. Options and SARs awarded to executives are granted at the closing price of the shares on the date of grant and, subject to the award agreements, will expire 10 years from the grant date. In the event that an employee’s employment terminates due to his/her death or permanent disability, unvested awards would generally vest, and the employee or his/her estate may exercise the options and SARs for a period of three years. In the event that an employee’s employment is terminated by the Company for cause, all unvested restricted shares would be forfeited and all unvested and vested and unexercised options and SARs would be forfeited. In the event that an employee’s employment terminates (other than for cause) after retirement age, unvested awards would continue to vest on the schedule set forth in the applicable agreement so long as the employee does not engage in a competitive activity. If the employee does engage in a competitive activity, then any unvested awards would be forfeited and the holder would have a reduced period in which to exercise vested options and SARs.

Double Trigger Change-in-Control Provision

The award agreements for the named executive officers provide that, in the event that the employee’s employment is terminated by the Company other than for cause or by the employee for good reason within two years following the consummation of a change in control, unvested awards would immediately vest, and the options and SARs would have a remaining term of 90 days from termination. In the event of termination for any reason other than as indicated above in this section, all unvested awards would be forfeited, and the holder may exercise vested options and SARs for a period of 90 days from termination. The foregoing description is qualified in its entirety by reference to the award agreements.

Each non-employee member of our Board of Directors is entitled to receive an annual cash retainer fee in the amount of $100,000 (commencing May 2016, the annual retainer will be $125,000). Each such director may elect to receive this retainer fee in the form of common shares instead of cash. If so elected, the number of shares distributed to the non-employee director would be equal to 100% of the amount of the annual retainer fee otherwise payable divided by the fair market value of our common shares. Each non-employee director also receives a meeting fee of $2,500 for each Board meeting attended and $1,500 for each committee meeting attended. In addition, each non-employee director serving as chairman of the audit committee receives an annual fee of $50,000 , and other members of the audit committee receive an annual fee of $25,000 . Each non-employee director serving as a chairman of a committee other than the audit committee receives an annual fee of $5,000 (commencing May 2016, the annual fee for the chairman of the finance, investment and risk committee will be $15,000 and the chairmen of the other committees will be $10,000). Accordingly, this column includes the annual retainer (whether paid in cash or, at the election of the director, in common shares), meeting fees and committee chairman and retainer fees, as applicable. For the 2015-2016 annual period, Messrs. Doppstadt, Paglia and Sunshine received their annual retainer fees in the form of cash and Ms. Mulligan and Messrs. Bunce, Lee, Lillikas, Pasquesi and Posner received their annual retainers in the form of 1,601 common shares. Mr. Meenaghan retired from the Board of Directors in 2015.

(2)

Each year, the non-employee directors are granted a number of restricted shares equal to $75,000 divided by the closing price on the date of grant ( i.e., the first day of the annual period of compensation for the non-employee directors), and such shares vest on May 1st of the following year. The grant date fair value indicated in the table has been calculated in accordance with FASB ASC Topic 718 Compensation—Stock Compensation. On May 7, 2015, Ms. Mulligan and Messrs. Bunce, Doppstadt, Lee, Lillikas, Paglia, Pasquesi, Posner and Sunshine received 1,201 restricted common shares. All of such shares will vest on May 1, 2016.

The aggregate number of share awards outstanding ( i.e., unvested) as of December 31, 2015 for Ms. Mulligan and Messrs. Bunce, Doppstadt, Lee, Lillikas, Paglia, Pasquesi, Posner and Sunshine was 1,201 common shares. In addition, as of December 31, 2015 , Mr. Vollaro had 224,250 outstanding stock options/SARs, which were awarded while he was chief financial officer of the Company. For additional information on ownership of the Company’s securities, please refer to “Security Ownership of Certain Beneficial Owners and Management.”


(3)	The amounts in the “All Other Compensation” column for Ms. Mulligan and Messrs. Bunce, Lee, Paglia, Pasquesi, Posner, and Sunshine include matching gifts made under the Company’s matching gift program. For Mr. Meenaghan, the amount represents the value of his retirement gift.


(4)	Mr. Vollaro is a senior advisor and an employee of the Company. Mr. Vollaro’s employment agreement provides that he receives an annual base salary of $250,000 and a bonus determined by the compensation committee and the Board of Directors for his role as senior advisor of the Company.

Table of Contents

chairman of the underwriting and oversight committee and is a member of the finance, investment and risk committee of the Board. A description of Mr. Vollaro’s employment agreement is included below.

(5)

The amount for Mr. Vollaro includes: (a) $32,500 in contributions to our defined contribution plans and (b) $5,563, which represents an additional payment to reimburse Mr. Vollaro for the approximate amount of additional tax liability for club dues. In addition, the total amount also includes the payment for club dues, life insurance premiums and tax preparation services, which did not exceed the greater of $25,000 or 10% of the total amount of these benefits for Mr. Vollaro.

In addition to the above arrangements, all non-employee directors are entitled to reimbursement for their reasonable out-of-pocket expenses in connection with their travel to and attendance at meetings of the Board of Directors or committees. Directors who are also employees of ACGL or its subsidiaries receive no cash compensation for serving as directors or as members of Board committees. The Company also provides a matching gift program pursuant to which the Company matches eligible contributions by non-employee directors to qualified charitable organizations. During 2015 , the Company made an aggregate of approximately $313,000 in matching contributions on behalf of the non-employee directors.

Employment Agreement of John D. Vollaro

ACGL and John Vollaro entered into an employment agreement with a term extending through April 1, 2017 . The employment period will continue on the same terms and conditions for an indefinite period until terminated by either party by providing at least six months’ prior written notice to the other party. Pursuant to the agreement, Mr. Vollaro has served as Senior Advisor of ACGL since April 1, 2009. Mr. Vollaro’s base salary is paid at the rate $250,000 per annum, and the target rate for the annual cash bonus is 100% of the annual base salary. Mr. Vollaro is eligible to receive annual cash bonuses and share-based awards at the discretion of ACGL’s Board of Directors and is also entitled to participate in employee benefits programs such as major medical, life insurance and disability insurance, the cost of preparation of annual tax returns and associated tax planning, and other fringe benefits customarily provided to similarly situated senior executives. His agreement also provides that the Company will reimburse him, on an after-tax basis, for his reasonable expenses incurred in traveling between Bermuda and the United States.

The agreement provides that if Mr. Vollaro’s employment is terminated without cause or for good reason, he will be entitled to receive an amount equal to the sum of the total remaining base salary and target annual bonus which would have been paid to Mr. Vollaro under his employment agreement for the period through the later of (a) the end of the original term of the agreement and (b) six months after the date of termination of employment (the “Severance Amount”). The Severance Amount would be payable over 12 months. The agreement also provides that if Mr. Vollaro’s employment is terminated for cause, as a result of his resignation or leaving employment other than for good reason, as a result of death or permanent disability, or by written notice of the intention not to renew the agreement by us or Mr. Vollaro, he (or his estate) will be entitled to receive his base salary through the date of termination. The agreement further provides that if Mr. Vollaro’s employment is terminated by reason of death or permanent disability, he (or his estate) will also be entitled to receive for the period extending through the remainder of the employment period, an amount equal to the Severance Amount, in each case, (i) offset by any proceeds received from any insurance coverages provided by the Company, and (ii) such amount, will be paid to him (or his estate) promptly upon death or permanent disability, as applicable, and in no event later than March 15 of the calendar year following the calendar year of such termination of employment. Mr. Vollaro’s major medical insurance coverage benefits pursuant to his employment agreement will continue for 12 months after the date of termination (or until he is provided by another employer with benefits substantially comparable, with no pre-existing condition limitations, to the benefits provided by such plan) in the event that (1) his employment ends due to permanent disability, (2) he is terminated other than for cause or (3) he resigns for good reason.

Mr. Vollaro has agreed that, during the employment period and for a period of two years after termination of employment for cause or as a result of his resignation or leaving employment other than for good reason, he will not compete with the businesses of ACGL or any of its subsidiaries as such businesses exist or are in process or being planned as of the date of termination. If we terminate Mr. Vollaro’s employment without cause or he terminates for good reason, the term of his non-competition period will extend for one year following termination. Mr. Vollaro also agreed that he will not, for a period of two years following his date of termination, induce or attempt to induce any of our employees to leave his or her position with us or induce any customer to cease doing business with us.

Director Share Ownership Guidelines

In an effort to further align the interests of the non-employee directors with the interests of shareholders, the Company has adopted share ownership guidelines that require the directors to retain common shares having a value of at least three times the annual cash retainer fee payable to the director. Each non-employee director has five years to comply with the guidelines, and stock options, SARs and unvested restricted shares/units do not count toward the requirement. Until our non-employee directors meet their target ownership levels, they must retain an amount equal to 50% of the net profit shares received from Company equity awards until he or she has attained the applicable share ownership level. Net profit shares are the shares remaining after payment of the exercise price of an option and taxes owed on exercise of options or SARs, vesting of restricted stock, or vesting and payout under restricted stock units and performance shares.

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than 10% of our common shares, to file with the SEC initial reports of beneficial ownership and reports of changes in beneficial ownership of our equity securities. Such persons are also required by SEC regulation to furnish us with copies of all Section 16(a) reports they file.

Certain Relationships and Related Transactions

Generally, transactions with related persons are subject to the review by the Board of Directors of ACGL. The Board of Directors has adopted written procedures regarding the review of transactions involving companies affiliated with a company in which a non-employee director or executive officer of ACGL has a material interest (each a “portfolio company”), on the one hand, and ACGL or one of its subsidiaries, on the other hand.

Under the procedures, these transactions must be reviewed and approved by the management of ACGL or the operating subsidiary entering into the transaction (as applicable), and the terms of such transaction should be arm’s-length or on terms that are otherwise fair to ACGL and its subsidiaries. In addition, these transactions also require the approval of ACGL under its holding company oversight guidelines, except for the following: (1) ordinary course transactions pursuant to which any insurance subsidiary of ACGL writes a direct insurance policy for a portfolio company unless a non-U.S. subsidiary will receive $3 million or more in annual premiums and (2) a transaction in which a U.S.-based subsidiary of ACGL (a) assumes reinsurance from, or cedes reinsurance to, a portfolio company or (b) provides direct insurance to a portfolio company pursuant to which such U.S.-based insurance subsidiary of ACGL will receive $3 million or more in annual premiums, in which case, the general counsel of Arch Capital Services Inc. should be pre-notified and appropriate steps will be implemented based on the transaction. In reviewing these proposed transactions, the effects, if any, on the independence of the relevant directors are considered under the governing NASDAQ and SEC standards. Any applicable regulatory, tax and ratings agency matters are also considered. Under these procedures, the Board of Directors is provided with an update of related party transactions entered into by the Company in accordance with the procedures on a regular basis.

Graham B. Collis, a director of certain of our non-U.S. subsidiaries, is a director of the law firm of Conyers Dill & Pearman Limited, which provides legal services to the Company and its subsidiaries.

See also “Compensation Committee Interlocks and Insider Participation” for a description of transactions with certain related persons.

(“BCM”) in the ordinary course of business to manage a global equity portfolio based on the Baron Real Estate Strategy. The portfolio totaled $114.6 million at December 31, 2015 , compared to $155.0 million at December 31, 2014 . Arch Re (Bermuda) recorded $0.8 million of fees to BCM during 2015 . Based on a Schedule 13G/A filed in February 2016, The Baron Capital Group, Inc., an affiliate of BCM, owns more than 5% of the outstanding common shares of ACGL.

Based on a Schedule 13G/A filed in February 2016 , BlackRock owned approximately 6.2% of the outstanding common shares of ACGL as of February 10, 2016.

During 2015 , the Company incurred approximately $12.1 million of fees, in the aggregate, under these services arrangements with BlackRock.

During 2015, a subsidiary of the Company, Arch Re (U.S.), invested $8 million for an approximately 19% equity interest in Sojourner Holding Company LLC, which through its subsidiary Spinnaker Insurance Company, conducts a property-focused program business. In connection with its investment, the Company has the right to appoint one member of Sojourner’s board of managers, and also has a right of first refusal to provide, on market terms, a specified percentage of certain reinsurance purchased by Spinnaker. At the same time, one of the Company’s directors, John Pasquesi, invested $10 million on the same economic terms for an approximately 24% equity interest in Sojourner. Mr. Pasquesi also has the right to appoint one member of Sojourner’s board of managers.

PROPOSAL 3—APPROVAL OF THE AMENDED AND RESTATED ARCH CAPITAL GROUP LTD. 2007 EMPLOYEE SHARE PURCHASE PLAN

Our Board of Directors has adopted, subject to shareholder approval, the Amended and Restated Arch Capital Group Ltd. 2007 Employee Share Purchase Plan (the “Share Purchase Plan”) increasing the number of shares available for issuance thereunder by 1,000,000 common shares. Prior to the amendment and restatement, 563,259 common shares remained available for issuance under the Share Purchase Plan. The following summary of the Share Purchase Plan is qualified in its entirety by express reference to the text of the Share Purchase Plan, which is attached as Appendix A to this proxy statement.

The purpose of the Share Purchase Plan is to give employees of ACGL and its subsidiaries an opportunity to purchase common shares through payroll deductions, thereby encouraging employees to share in the economic growth and success of ACGL and its subsidiaries.

The Share Purchase Plan will be administered by the compensation committee of our Board of Directors. Subject to the express provisions of the Share Purchase Plan, the compensation committee has the power to determine the terms and conditions of each offering of common shares to employees thereunder. The compensation committee also has authority to adopt and revise rules, guidelines and practices governing the plan, to interpret the terms and provisions of the plan and any offering made thereunder, and to otherwise supervise the administration of the plan.

After the amendment and restatement, a total of 1,563,259 common shares will be reserved for issuance under the Share Purchase Plan. The number of such shares is subject to equitable adjustment by the compensation committee in the event of stock dividends, recapitalizations and other similar corporate events. The per share closing price of our common shares on March 22, 2016 was $70.50.

All employees of the Company or any of its participating subsidiaries will be eligible to purchase common shares under the plan. The participating subsidiaries will be those designated by the compensation committee to participate in the Share Purchase Plan. Up to approximately 2,000 employees are currently eligible to participate in the Share Purchase Plan.

The plan is designed to qualify as an “employee share purchase plan” under Section 423 of the Code. The plan will allow participating employees to purchase common shares through payroll withholding. The plan provides for consecutive six-month offering periods (or other periods of not more than 27 months as determined by the compensation committee) under which participating employees can elect to have amounts withheld from their total compensation during the offering period and applied to purchase common shares of the Company at the end of the period. Unless otherwise determined by the compensation committee before an offering period, the purchase price will be 85% of the fair market value of the common shares at the beginning of the offering period. Unless otherwise determined by the compensation committee, the maximum number of common shares that may be purchased by an employee in any offering is 3,000 shares, subject to equitable adjustment as described above. In addition, applicable Code limitations specify, in general, that a participant’s right to purchase stock under the plan cannot accumulate at a rate in excess of $25,000 (based on the value at the beginning of the applicable offering periods) per calendar year.

A participant may elect to have payroll deductions made under the Share Purchase Plan for the purchase of common shares in an amount not to exceed 20% of the participant’s compensation. Compensation for purposes of the Share Purchase Plan means total cash compensation, including regular pay, overtime pay, shift premium, commissions and annual bonuses, and it also includes pre-tax employee contributions under a section 401(k) plan or Section 125 plan. Contributions to the Share Purchase Plan will be on an after-tax basis. A participant may terminate his or her payroll deductions at any time.

A share purchase account will be established for each participant in the Share Purchase Plan. Amounts deducted from participants’ paychecks will be credited to their accounts. Unless otherwise determined by the compensation committee, no interest will accrue with respect to any amounts credited to the accounts. As of the last day of each offering period, the amount credited to a participant’s share purchase account will be used to purchase the largest number of whole shares (not to exceed 3,000 shares, subject to equitable adjustment as described above) at the price as determined above. The common shares will be purchased directly from ACGL. No brokerage or other fees will be charged to participants. Any balance in a participant’s account will be returned to the participant, except where such remaining balance represents a fractional share. In such cases, the fractional share balance shall be carried forward and applied, subject to the participating employee’s withdrawal right, toward the purchase of additional stock by the participating employee in the subsequent offering.

Table of Contents

If the aggregate share purchase account to be used for the purchase of common shares as of the last day of an offering period would purchase more shares than are reserved for purchase and sale under the Share Purchase Plan, the number of shares which would otherwise be purchased for each participant will be reduced proportionately, the remaining account balance of each participant will be distributed and the Share Purchase Plan will terminate automatically upon the distribution of the remaining account balances.

A participant may withdraw from participation in the Share Purchase Plan at any time during an offering period by providing notice to ACGL. Upon withdrawal, a participant’s account balance will be distributed as soon as practicable and no common shares will be purchased. Rights to purchase common shares under the Share Purchase Plan are exercisable only by the participant and are not transferable.

With respect to employees of the Company or any subsidiary who reside or work outside the United States, the compensation committee may, in its sole discretion, adopt rules or procedures relating to the operation and administration of the Share Purchase Plan to accommodate the specific requirements of local laws and procedures. The compensation committee may also, where it deems it appropriate, establish one or more separate plans to reflect such amended or varied rules and procedures.

The Share Purchase Plan will terminate when all common shares authorized to be issued under it have been exhausted. The Board of Directors may discontinue the Share Purchase Plan at any time and may amend it from time to time. Amendments may be made without shareholder approval, except as required to satisfy Section 423 of the Code.

United States Federal Income Tax Consequences

The following is a summary of the United States federal income tax consequences to employees participating in the Share Purchase Plan and to ACGL and its subsidiaries, based upon current provisions of the Code, the treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, and does not address the consequences under any other applicable tax laws. The provisions of the Code, regulations thereunder and related interpretations are complicated and their impact in any one case may depend upon the particular circumstances relating thereto.

A participating employee will not recognize income at the time a purchase right is granted to such employee at the commencement of an offering period or when the employee exercises such right and purchases common shares at the end of an offering period. An employee will be taxed on amounts withheld from salary under the Share Purchase Plan as if actually received, and ACGL or one of its participating subsidiaries will be entitled to deduct a corresponding amount.

If a participating employee disposes of shares purchased pursuant to the plan after one year from the end of the applicable offering period and two years from the beginning of the applicable offering period, the employee must include in gross income as compensation (as ordinary income and not as capital gain) for the taxable year of disposition an amount equal to the lesser of (1) the excess of the fair market value of the shares at the beginning of the applicable offering period over the purchase price computed on the first day of the offering period or (b) the excess of the fair market value of the shares at the time of disposition over their purchase price. Thus, if the one and two-year holding periods described above are met, the participating employee’s ordinary compensation income will be limited to the discount available on the first day of the applicable offering period. If the amount recognized upon such a disposition by way of sale or exchange of the shares exceeds the purchase price plus the amount, if any, included in income as ordinary compensation income, the excess will be long-term capital gain. If the one and two-year holding periods described above are met, then ACGL and its participating subsidiaries will not be entitled to any income tax deduction.

If the participating employee disposes of the shares within two years from the beginning of the applicable offering period or one year from the end of the applicable offering period, the employee will recognize ordinary income at the time of disposition which will equal the excess, if any, of the fair market value of the shares on the date the participating employee purchases the shares ( i.e ., the end of the applicable offering period) over the amount paid for the shares. ACGL or a participating subsidiary that employs the employee will generally be entitled to a corresponding income tax deduction. The excess, if any, of the amount recognized on disposition of the shares over their fair market value on the date of purchase ( i.e. , the end of the applicable offering period) will be short-term capital gain, unless the participating employee’s holding period for the shares (which will begin at the time of purchase at the end of the offering period) is more than one year. If the participating employee disposes of the shares for less than the purchase price for the shares, the difference between the amount recognized and such purchase price will be a long- or short-term capital loss, depending upon the holding period for the shares.

PROPOSAL 4—TO APPROVE AMENDING SECTION 46(1) OF THE COMPANY’S BYE-LAWS TO IMPLEMENT MAJORITY VOTING FOR DIRECTORS IN UNCONTESTED ELECTIONS

At its meeting on February 26, 2016, the Board of Directors considered amending the Company’s bye-laws to provide for the inclusion of a majority voting standard for the election of directors. Following its review, our Board unanimously approved the proposed amendments and recommends their approval and adoption by the shareholders of the Company.

The Company currently has a plurality vote standard for the election of directors, which provides for the continuation of service of a director until his or her successor is elected and qualified. In determining to incorporate the majority vote standard into the Company’s bye-laws, the Board considered a number of factors, including communications with shareholders and a review of the general market including the Company’s peer group. The Board determined that the majority vote standard heightens individual director accountability to the Company’s shareholders and supports the Company’s ongoing efforts to adopt best practices in corporate governance.

The proposal would amend Section 46(1) of the Company’s bye-laws to provide that in any uncontested election of directors, each director will be elected by a majority of the voting power represented by the votes cast. A majority of the voting power represented by the votes cast will mean that the number of votes cast “for” exceeds the number of votes cast “against” or “withheld”, and will not include abstentions or shares present at the meeting as to which a shareholder gives no authority or discretion (a broker non-vote). The proposal provides an exception to the majority vote standard in the event of a director election in which the number of director nominees exceeds the number of directors to be elected. In this event, each director will be elected by a plurality of the votes cast for such director.

If this proposal is approved by our shareholders, our Board will amend our Corporate Governance Guidelines to provide that in an uncontested election, any nominee for director who fails to receive a majority of the votes cast in such election will be obligated to tender his or her resignation to the Board of Directors. The Nominating Committee or other committee designated by our Board will consider any such resignation and make a recommendation to the Board whether to accept or reject the resignation. The Board would be required to accept or reject the resignation within 90 days following certification of the election results, taking into account all relevant facts and circumstances, and will publicly disclose its reasons if the resignation is not accepted.

The full text of Section 46(1) of the Company’s bye-laws, marked to show the changes from our current provision, is attached to this proxy statement as Appendix B.

PROPOSAL 5—APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee of the Board of Directors proposes and recommends that the shareholders appoint the firm of PricewaterhouseCoopers LLP to serve as independent registered public accounting firm of ACGL for the year ending December 31, 2016 . Unless otherwise directed by the shareholders, proxies will be voted for the appointment of PricewaterhouseCoopers LLP to audit our consolidated financial statements for the year ending December 31, 2016 . A representative of PricewaterhouseCoopers LLP will attend the annual general meeting and will have an opportunity to make a statement and respond to appropriate questions.

(1)

The above table excludes fees related to audit work for Watford, which are subject to approval by Watford’s board of directors and its audit committee. In March 2014, the Company acquired an approximately 11% equity interest in Watford’s common shares and the right to designate two members of Watford’s five member board of directors. We consolidate Watford’s results under applicable accounting guidance. Please see note 4, “Variable Interest Entity and Noncontrolling Interests,” of the notes accompanying our consolidated financial statements included in our 2015 Annual Report, for additional information about our ownership interest in Watford.

(2)

“Audit Fees” consisted primarily of fees for the integrated audit of our annual financial statements and internal control over financial reporting, review of our financial statements included in our quarterly reports on Form 10-Q, statutory audits for our insurance subsidiaries and review of SEC registration statements. The audit fees for the year ended December 31, 2015 increased primarily due to audit work related to additional legal entities created or acquired by the Company and additional work related to the Company’s growing mortgage insurance operations.


(3)	“Audit Related Fees” consisted of the audit of the Company’s benefit plans and other audit related services, which for 2014 included fees in connection with the acquired mortgage insurance operations and our initiative in launching Watford.


(4)	“Tax Fees” consisted primarily of fees for tax compliance, tax advice and tax planning.


(5)	“All Other Fees” consisted primarily of fees related to software licensing fees.

The audit committee has considered whether the provision of these services is compatible with maintaining PwC’s independence. The audit committee approves all audit and permissible non-audit services performed for us by PwC, our independent registered public accounting firm. Prior to engagement, the audit committee pre-approves these services by category of service. The fees are budgeted and the audit committee requires the independent registered public accounting firm and management to report actual fees compared to the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the audit committee requires specific pre-approval before engaging the independent registered public accounting firm. The audit committee delegates pre-approval authority to one or more of its independent members. To the extent applicable, the member to whom such authority is delegated reports, for informational purposes only, any pre-approval decisions to the audit committee at its next scheduled meeting.

PROPOSAL 6—ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) allows our shareholders to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules.

We have a “pay-for-performance” philosophy that forms the foundation of all decisions regarding compensation of our named executive officers. This compensation philosophy, and the compensation programs approved by the compensation committee of our Board of Directors, is central to our ability to attract, retain and motivate individuals who can achieve superior results. Our approach has resulted in our ability to attract and retain the executive talent necessary to guide us during all phases of the underwriting cycle.

We are requesting shareholder approval of the compensation of our named executive officers pursuant to the compensation disclosure rules of the SEC, including the “Compensation Discussion and Analysis,” the compensation tables and any related material disclosed in this proxy statement. This vote is not intended to address any one specific item of compensation, but instead the overall compensation of our named executive officers and the policies and practices described in this proxy statement.

This vote is advisory and therefore not binding on the Company, the compensation committee of the Board of Directors or the Board. The Board and the compensation committee value the views of our shareholders and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, we will consider those shareholders’ concerns and will evaluate whether any actions are necessary to address those concerns.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE SEC.

The Committee may (but need not) permit employee contributions to be made by means other than payroll deductions, provided that in no event shall an employee’s contributions (excluding interest, if any, credited pursuant to Section 7(a) below) from all sources in any Offering exceed twenty percent of his or her Total Compensation with respect to such Offering or such lesser amount as the Committee may prescribe.

Employee contributions and any interest credited to the payroll deduction accounts of Participating Employees need not, unless required by applicable law, be segregated from other corporate funds and, to the extent permitted by applicable law, may be used for any corporate purpose.

(b) At such times as the Committee may permit and subject to such rules and procedures as the Committee may prescribe, a Participating Employee may suspend his or her payroll deduction during an Offering, or may withdraw the balance of his or her payroll deduction account and thereby withdraw from participation in an Offering.

(c) Any balance remaining in an employee’s payroll deduction account after shares have been purchased in an Offering pursuant to Section 8(b) below will be refunded to the Participating Employee, except that, unless otherwise determined by the Committee, any such remaining balance in an amount representing a fractional share shall be carried forward and applied, subject to the Participating Employee’s withdrawal right, toward the purchase of additional stock by the Participating Employee in the subsequent Offering. Upon termination of the Plan, all amounts in the accounts of Participating Employees shall be carried forward into their payroll deduction accounts under a successor plan, if any, or refunded to them, as the Committee may decide.

(d) In the event of the termination of a Participating Employee’s employment for any reason, his or her participation in any Offering under the Plan shall cease, no further amounts shall be deducted pursuant to the Plan and the balance in the employee’s account shall be paid as soon as practicable following such termination of employment to the employee, or, in the event of the employee’s death, to the employee’s beneficiary designated under this Plan or, in the absence of such a beneficiary designation, to the employee’s estate.

The purchase price of such shares under such options shall be determined in accordance with Section 8(c) below. The Company’s obligation to sell and deliver Common Stock in any Offering or pursuant to any such option shall be subject to the approval of any governmental authority whose approval the Committee determines it is necessary or advisable to obtain in connection with the authorization, issuance, offer or sale of such Common Stock.

(b) As of the last day of the Offering, the payroll deduction account of each Participating Employee shall be totaled. Subject to the provisions of Section 7(b) above and 8(d) below, if such account contains sufficient funds as of that date to purchase one or more whole or partial shares of Common Stock at the price determined under Section 8(c) below, the Participating Employee shall be conclusively deemed to have exercised the option granted pursuant to Section 8(a) above for as many whole or partial shares of Common Stock as the amount of his or her payroll deduction account (including any contributions made by means other than payroll deductions and including any interest credited to the account) at the end of the Offering can purchase (but in no event for more than the total number of shares that are subject to the option); such employee’s account will be charged for the amount of the purchase and for all purposes under the Plan the employee will be deemed to have acquired the shares on that date; and either a stock certificate representing such shares will be issued to him or her, or the Company’s record keeper will make an entry on its books and records evidencing that such shares have been duly issued or transferred as of that date, as the Committee may direct. Notwithstanding any provision of the Plan to the contrary, unless otherwise determined by the Committee, fractional shares may not be purchased under the Plan. Any option granted pursuant to Section 8(a) above which is not deemed exercised as of the last day of the Offering in accordance with the foregoing provisions of this Section 8(b) shall expire on that date.

(c) Unless the Committee determines before the first day of an Offering that a different price that complies with Section 423 of the Code shall apply, the price at which shares of Common Stock may be purchased under each option granted pursuant to Section 8(a) above shall be an amount equal to 85 percent of the Fair Market Value of the Common Stock at the beginning of the Offering Period.

(d) In addition to any other limitations set forth in the Plan, no employee may be granted an option under the Plan which permits his or her rights to purchase stock under the Plan, and any other stock purchase plan of his or her employer corporation and its Parent and Subsidiary that is qualified under Section 423 of the Code, to accrue at a rate which exceeds US$25,000 of the Fair Market Value of such stock (determined at the time such option is granted) for each calendar year in which the option is outstanding at any time. The Committee may further limit the amount of Common Stock which may be purchased by any employee during an Offering in accordance with Section 423(b)(5) of the Code.

9. No Transfer .
