In addition, our Code of Business Conduct may be found on our Web site at www.mcdermott.com at “WHO WE ARE — Ethics.”

Item 1 – Election of Directors

Unless otherwise directed, the persons named as proxies on the enclosed proxy card intend to vote “FOR” the election of each of the nominees. If any nominee should become unavailable for election, the shares will be voted for such substitute nominee as may be proposed by our Board of Directors. However, we are not aware of any circumstances that would prevent any of the nominees from serving.

Our Board of Directors recommends that stockholders vote “FOR” each of the nominees named below.

Election Process

Our Articles of Incorporation provide that, at each annual meeting of stockholders, all directors shall be elected annually for a term expiring at the next succeeding annual meeting of stockholders or until their respective successors are duly elected and qualified.

Trice will stand for reelection as directors at this year’s Annual Meeting, each for a term of one year.

Our By-Laws provide that (1) a person shall not be nominated for election or reelection to our Board of Directors if such person shall have attained the age of 72 prior to the date of election or reelection, and (2) any director who attains the age of 72 during his or her term shall be deemed to have resigned and retired at the first Annual Meeting following his or her attainment of the age of 72. Accordingly, a director nominee may stand for election if he or she has not attained the age of 72 prior to the date of election or reelection. Pursuant to these By-Law requirements, Roger A. Brown will retire from our Board after eleven years of service, effective at this year’s Annual Meeting.

2017 Nominees

In nominating individuals to become members of the Board of Directors, the Governance Committee considers the experience, qualifications, attributes and skills of each potential member. Each nominee brings a strong and unique background and set of skills to the Board, giving the Board, as a whole, competence and experience in a wide variety of areas. The Governance Committee and the Board of Directors considered the following information, including the specific experience, qualifications, attributes or skills of each individual, in concluding each was an appropriate nominee to serve as a member of our Board for the term commencing at this year’s Annual Meeting (ages are as of May 5, 2017).

Such limits provide that any director who is a chief executive officer or other senior executive of a public company should serve on no more than two public company boards, and any other director should serve on no more than three public company boards, in both instances including the McDermott Board. Any proposed service in excess of these limits will be considered on a case by case basis.

In addition, the Governance Committee also considers it desirable that candidates contribute positively to the collaborative culture among Board members and possess professional and personal experiences and expertise relevant to our business and industry. The Governance Committee solicits ideas for possible candidates from a number of sources, including independent director candidate search firms, members of the Board and our senior level executives.

The Board recognizes the benefits of a diversified board and believes that any search for potential director candidates should consider diversity as to gender, race, ethnic background and personal and professional experiences. Additionally, our Corporate Governance Guidelines provide that any independent director search firm retained to assist the Governance Committee in identifying director candidates shall seek to include diverse candidates in terms of race, ethnic background and gender.

Director Independence

The New York Stock Exchange (“NYSE”) listing standards require our Board of Directors to be comprised of at least a majority of independent directors. In 2015, however, the Board amended our Corporate Governance Guidelines to require that, with the exception of the Chief Executive Officer, the Board be comprised entirely of independent directors. For a director to be considered independent, our Board must determine that the director does not have any direct or indirect material relationship with us. To assist it in determining director independence, and as permitted by NYSE rules then in effect, the Board previously established categorical standards which conform to, or are more exacting than, the independence requirements in the NYSE listing standards. These standards are contained in our Corporate Governance Guidelines, which can be found on our Web site at www.mcdermott.com under “INVESTORS — Corporate Governance.”

Based on these independence standards, our Board of Directors has affirmatively determined that the following directors are independent and meet our categorical independence standards:

John F. Bookout, III		Gary P. Luquette
Roger A. Brown		William H. Schumann, III
Stephen G. Hanks		Mary L. Shafer-Malicki
Erich Kaeser		David A. Trice

In determining the independence of the directors, our Board considered ordinary course transactions between us and other entities with which the directors are associated, none of which were determined to constitute a material relationship with us. Messrs. Brown, Luquette, Kaeser, Schumann and Trice have no relationship with McDermott, except as a director and stockholder. Messrs. Bookout and Hanks and Ms. Shafer-Malicki are directors of entities with which we transact business in the ordinary course. Our Board also considered contributions by us to charitable organizations with which the directors were associated. No director is related to any executive or significant stockholder of McDermott, nor is any director, with the exception of Mr. Dickson, a current or former employee of McDermott.

Director Nominations

Any stockholder may nominate one or more persons for election as one of our directors at the annual meeting of stockholders if the stockholder complies with the notice, information and consent provisions contained in our By-Laws. See “Stockholders’ Proposals” in this proxy statement and our By-Laws, which may be found on our Web site at www.mcdermott.com at “INVESTORS — Corporate Governance.”

The Governance Committee will consider candidates identified through the processes described above and will evaluate the candidates, including incumbents, based on the same criteria. The Governance Committee also takes into account the contributions of incumbent directors as Board members and the benefits to us arising from their experience on the Board. Although the Governance Committee will consider candidates identified by stockholders, the Governance Committee has sole discretion whether to recommend those candidates to the Board.

The Board’s Role and Responsibilities

Overview

The Board’s Key Responsibilities include:

The Board’s Role in Risk Oversight

As part of its oversight function, the Board is actively involved in overseeing risk management through our Enterprise Risk Management (“ERM”) program, which includes periodic reporting through an area and corporate ERM structure. In connection with the ERM program, the Board exercises its oversight responsibility with respect to key external, strategic, operational and financial risks and discusses the effectiveness of current efforts to mitigate certain focus risks as identified by senior management and the Board through anonymous risk surveys.

Board and Committees Risk Oversight Responsibilities

Full Board Although the Board is ultimately responsible for risk oversight, the Board is assisted in discharging its risk oversight responsibility by the Audit, Compensation and Governance Committees. Each committee oversees management of risks, including, but not limited to, the areas of risk summarized below, and periodically reports to the Board on those areas of risk:
Audit Committee Oversees management of risks related to our financial statements and the financial reporting process		Compensation Committee Oversees management of risks related to our compensation policies and practices applicable to executives, employee benefit plans and the administration of equity plans		Governance Committee Oversees management of risks related to succession planning for the Chief Executive Officer and other members of executive management and our Ethics and Compliance Program (excluding responsibilities assigned to the Audit Committee)

Corporate Governance

At their respective November 2016 meetings, each committee undertook an assessment of those areas of risk oversight that were delegated to it and provided a report to the Board. Also, at its November 2016 meeting, the Board received an ERM report and performed an assessment and review of the risks described in that report that were not delegated to the committees.

Regarding risks relating to the design of our compensation programs, the Compensation Committee, with assistance from its independent compensation consultant, Pay Governance LLC, regularly reviews and assesses our compensation policies and practices to ensure that they are appropriate in terms of the level of risk-taking and in line with our business strategies and the interests of our stockholders. The Compensation Committee has designed our compensation programs to encourage performance focused on long-term stockholder value, promote company growth and allow for appropriate levels of risk-taking but to discourage excessive risk-taking. Based on the findings of the risk assessment performed at its November 2016 meeting, the Compensation Committee concluded that the risks arising from our compensation policies and practices are aligned with stockholders’ interests and not reasonably likely to have a materially adverse impact on us.

Stockholder Engagement

The Board oversees and is committed to ongoing stockholder dialogue on governance and compensation matters and places considerable weight on stockholder feedback in making decisions impacting our governance processes and compensation programs. In 2016, our Board engaged in a stockholder outreach program to discuss our stockholders’ perspectives on our governance and compensation policies and practices. We reached out to stockholders representing approximately 40% of our outstanding common stock and conducted face-to-face or telephonic meetings with holders of approximately 30%, which were led by either our independent Compensation Committee Chair or our independent Governance Committee Chair. This engagement process provided us with constructive stockholder feedback on governance and compensation topics, such as board refreshment, board evaluations, annual and long-term incentive programs and disclosure around our executive compensation programs.

The feedback received during the course of our outreach efforts was fully reported to and assessed by the Board and its relevant committees. Details as to our 2016 engagement effort and actions taken in response to stockholders’ compensation-related comments are provided on pages 11 and 38 of this proxy statement. Stockholders were highly supportive of our corporate governance processes and were supportive of the Board’s current tenure mix and commitment to director refreshment. In response to stockholder input received on annual Board and Committee performance evaluations generally, we enhanced our process by bringing in a third party to conduct the 2016 Board, Committee and Independent Director annual evaluations. Additionally, in response to general comments received relating to “over boarding,” the Board approved limits on the number of boards on which McDermott directors may serve. The Board will continue to seek stockholder input to identify and proactively address important governance and compensation issues.

Board Refreshment and Succession Planning

We are committed to a strong board refreshment process. As part of our commitment to board refreshment we impose a mandatory director retirement age of 72, require Committee Chairs to rotate after five years of service and annually review Committee composition and individual director skills and qualifications. Additionally, our Governance Committee, typically with the assistance of a third party search firm, identifies and considers new director candidates who have expertise that would complement and enhance the current Board’s skills and experience. Our commitment to board refreshment has resulted in a Board with a well-balanced tenure, with three directors who have served four years or less, two directors who have served between five and six years and four directors who have served seven years or more.

Director Succession Planning Process

Succession Planning

Identification of Candidates

Meeting with Candidates

Decision and Nomination

The Governance Committee implements an ongoing succession planning process, seeking out director candidates to join our Board in light of our emerging business needs of our business and our current Board’s composition

To ensure a robust search process and access to a wide range of qualified candidates, the Governance Committee works closely with an independent search firm to identify and evaluate director candidates in light of our Board’s structure, tenure and qualifications

Potential director candidates are interviewed by our Chair of the Board, CEO, the Governance Committee and other available directors

The Governance Committee recommends to the full Board for nomination those director candidates with the skills and experience that would most benefit the current Board and best serve the interests of McDermott and its stockholders

Board and Committee Evaluations

Our Board recognizes the critical role of annual Board and committee evaluations in ensuring each are functioning effectively. The Governance Committee annually reviews the Board and committee evaluation process in consideration of recent best practices and input from the directors. To that end, and in response to stockholder input received during the 2016 stockholder outreach program, the Governance Committee enhanced the evaluation process by utilizing a third party to help conduct the annual Board and committee performance evaluations conducted in early 2017.

	Annual Board and Committee Evaluation Process
	Board Survey The third party facilitator worked with the Chair of the Board, the Governance Chair and selected directors and officers to set the scope and plan for the annual evaluations based on business strategy, board culture and observations on Board processes. The facilitator then conducted a written board survey to identify cultural and overall effectiveness issues.		Detailed Interviews The facilitator leveraged findings from the Board survey to obtain initial views and to create with the Governance Chair a customized interview guide. Using the interview guide, the facilitator conducted in person interviews with directors and selected officers.
	Full Board Discussion The facilitator compiled feedback and developed a summary of findings and recommendations, which was presented to the full Board for discussion and proposed enhancements.		Follow-Through The Board will consider the results of these evaluations in making decisions on Board agendas, structure, responsibilities, policies and practices, as appropriate. The facilitator will reach out to the Board later in the year to determine lasting impact of changes and any further steps.

Compensation Committee Interlocks and Insider Participation

All members of our Compensation Committee are independent in accordance with NYSE listing standards. No member of the Compensation Committee (1) was, during the year ended December 31, 2016, or had previously been, an officer or employee of McDermott or any of its subsidiaries, or (2) had any material interest in a transaction of McDermott or a business relationship with, or any indebtedness to, McDermott. No interlocking relationship existed during the year ended December 31, 2016 between any member of the Board of Directors or the Compensation Committee and an executive officer of McDermott.

Related Party Transactions

We have adopted a written Related Person Transaction Policy applicable to any individual transaction or series of related transactions, arrangements or relationships (including any indebtedness or guarantee of indebtedness) in which:

●	McDermott or any of its subsidiaries is, was or will be a participant;
●	any related person (as defined in the policy) has, had or will have a direct or indirect material interest; and
●	the amount involved exceeds $120,000.

This policy requires directors, director nominees and executive officers to provide written notice to the General Counsel (“GC”) of any potential Related Person Transaction involving, directly or indirectly, him or her or any of his or her immediate family members. Additionally, each director, director nominee and executive officer must complete an annual questionnaire designed in part to elicit and evaluate information about potential related person transactions and any related person relationships. All related person transactions requiring compliance with the policy as determined by the GC must be presented to the Governance Committee for review, approval, ratification or other action. The Governance Committee will approve or ratify a related person transaction only if it determines that, under all of the circumstances, the transaction is not inconsistent with the best interests of McDermott. There were no such transactions found to be directly or indirectly material to a related person required by SEC rules to be disclosed in this proxy statement.

EXECUTIVE COMPENSATION

Item 2 – Advisory Vote to Approve Named Executive Officer Compensation

We are asking our stockholders to vote on an advisory basis to approve the compensation of our NEOs (sometimes referred to as “say on pay”) in accordance with Section 14A(a)(1) of the Securities Exchange Act of 1934. The Board recommends a vote “FOR” this proposal because it believes that our compensation policies and practices are effective in achieving McDermott’s philosophy of providing compensation that:

●	attracts, motivates and retains well-qualified executives;
●	provides performance-based incentives to reward achievement of short and long term business goals and strategic objectives, while recognizing individual contributions; and
●	aligns the interests of our executives with those of our stockholders.

For the reasons discussed in the “Compensation Discussion and Analysis,” accompanying compensation tables and related narrative disclosures in this proxy statement, the Board of Directors unanimously recommends that stockholders vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the NEOs, as disclosed pursuant to Item 402 of Regulation S-K,including the Compensation Discussion and Analysis, compensation tables and accompanying narrative discussion in McDermott’s proxy statement relating to its 2017 annual meeting of stockholders, is hereby APPROVED.”

Although the resolution is non-binding, the Board of Directors and Compensation Committee will consider the outcome of the vote when making future compensation decisions.

Our Board of Directors recommends that stockholders vote “FOR” the advisory vote to approve named executive officer compensation.

Compensation Discussion & Analysis

Introduction

The following Compensation Discussion and Analysis, or CD&A, provides information relevant to understanding the 2016 compensation of our executive officers and former executive officers identified in the Summary Compensation Table, whom we refer to as our NEOs, with the exception of Mr. Stephen L. Allen, our former Senior Vice President, Human Resources, who we refer to as our Retired NEO. NEOs, as used in the CD&A, includes only the Named Executive Officers who remained employed in their same position with McDermott through the date of this proxy statement. For 2016, our NEOs and their respective titles were as follows:

●	David Dickson, our President and Chief Executive Officer;
●	Stuart A. Spence, our Executive Vice President and Chief Financial Officer;
●	Linh Austin, our Vice President, Middle East and Caspian;
●	Liane K. Hinrichs, our Senior Vice President, General Counsel and Corporate Secretary; and
●	Jonathan Kennefick, our Senior Vice President, Project Execution and Delivery.

The following discussion also contains statements regarding future individual and company performance targets and goals. These targets and goals are disclosed in the limited context of our compensation programs and should not be understood to be statements of management’s expectations or estimates of results or other guidance. We caution investors not to apply these statements in other contexts.

Executive Compensation

2016 Compensation Program

Compensation Philosophy

The Compensation Committee is committed to targeting reasonable and competitive total direct compensation for our NEOs, with a significant portion of that compensation being performance-based. Our compensation programs are designed to address business needs and provide competitive opportunities, but achievement of most of those opportunities depends on the attainment of performance goals and/or stock price performance. McDermott’s compensation programs are designed to provide compensation that:

Attracts, motivates and retains high-performing executives				Provides performance-based incentives to reward achievement of short and long-term business goals and strategic objectives while recognizing individual contributions				Aligns the interests of our executives with those of our stockholders

What We Pay and Why: Elements of Total Direct Compensation

Target Total Direct Compensation

The Compensation Committee seeks to provide reasonable and competitive compensation. As a result, it targets the elements of total direct compensation, or “TDC,” for our NEOs generally within approximately 15% of the median compensation of our market for comparable positions. Throughout this CD&A, we refer to compensation that is within approximately 15% of market median as “market range” compensation.

The Compensation Committee may set TDC or individual elements of TDC above or below the market range to account for a NEO’s performance, experience, tenure in the role, internal pay equity and other factors or situations that are not typically captured by looking at standard market data and practices and which the Compensation Committee deems relevant to the appropriateness or competitiveness of a NEO’s compensation.

When making decisions regarding individual compensation elements, the Compensation Committee also considers the effect on the NEO’s target TDC and target total cash-based compensation (annual base salary and annual incentives at target level), as applicable. The Compensation Committee’s goal is to establish target compensation for each element that, when combined, create a target TDC award for each NEO that is reasonable and competitive and supports our compensation philosophy and objectives.

Elements of Total Direct Compensation

Total direct compensation is comprised of three elements: annual base salary, annual incentive, and long-term incentives.

Annual Base Salary

We pay base salaries to provide a fixed level of compensation that helps attract and retain executives. Base salary levels recognize an executive officer’s experience, skill and performance, with the goal of being market competitive based on the officer’s role and responsibilities within the organization. Adjustments may be made based on individual performance, inflation, pay relative to market and internal pay equity considerations. No NEO received an increase in annual base salary in 2016.

Annual Incentive

The Compensation Committee administers our annual incentive compensation program under our Executive Incentive Compensation Plan, or EICP. The EICP is a cash incentive plan designed to motivate and reward our NEOs and other key employees for their contributions to strategic business goals and other factors that we believe drive our earnings and promote creation of stockholder value. In 2016, EICP bonus pool funding was 100% based on our financial performance, with each participant’s actual bonus award determined by achievement of the participant’s individual performance goals.

Financial Performance Goals. For 2016 EICP awards, the Compensation Committee approved financial metric performance goals based on consolidated operating income, consolidated free cash flow (defined as consolidated cash from operations less consolidated capital expenditures), order intake (including change orders) and operating margins on order intake, weighted as set forth below. McDermott established the 2016 financial performance goals with consideration of management’s internal forecast of 2016 financial results, with the exception of the operating income goals, which were established at an increase over the forecast 2016 results.

*	Due to the nature of our business, forward-looking Order Intake Operating Margin Threshold, Target and Maximum business goals are competitively sensitive and unable to be disclosed, although at this time we are able to disclose such goals after the end of the applicable performance period.

McDermott’s actual performance against the stated goals determines the funding for each financial performance goal, with the weighted sum of each funding multiple determining the financial metric result.

2016 Financial Performance Results Under the EICP. McDermott’s actual 2016 financial performance results against the stated performance goals under the EICP were as follows:

Financial Metric Performance Goal		Actual Result ($/%)		Funding Multiple		Weight		Weighted Funding Multiple
Operating Income		203.1M*		2.000x		25%		0.500x
Free Cash Flow		(49.9)M		2.000x		25%		0.500x
Order Intake		2,726.4M		0.000x		30%		0.000x
Order Intake Operating Margin**		5.20%		0.000x		20%		0.000x
Total EICP Bonus Pool Funding Multiple								1.000x

*

Actual result for Operating Income computed in accordance with generally accepted accounting principles in the U.S. was $142.3 million. In consideration of McDermott’s 2016 performance, however, the Compensation Committee approved adjustments to GAAP Operating Income for items that our management does not consider to be representative of our normal operations. See the Appendix for a reconciliation of the Non-GAAP to GAAP financial measure.

**

Due to the nature of our business, forward-looking Order Intake Operating Margin goals are competitively sensitive and unable to be disclosed, although at this time we are able to disclose those goals and actual results after the end of the applicable performance period.

Accordingly, each NEO was eligible to earn 1.0x of his or her target EICP award, subject to modification by the Compensation Committee, based on his or her achievement of individual performance goals.

Individual Performance Goals. Following the determination of the EICP bonus pool funding multiple, an individual participant’s award was determined based on the achievement of the participant’s individual performance goals. In no event could any NEO’s annual bonus exceed two times his or her target EICP award opportunity. The Compensation Committee had the discretion to reduce the amount of payout to any participant, even if performance goals were achieved.

Executive Compensation

Long-Term Incentives

The Compensation Committee believes that the interests of our stockholders are best served when a significant percentage of executive compensation is comprised of equity that appreciates in value contingent on increases in the value of our common stock and other performance measures that reflect improvements in McDermott’s business fundamentals. Therefore, LTI compensation represents the single largest element of our NEOs’ total direct compensation. The Compensation Committee maintained the performance-based component of LTI at 50% in 2016, after increasing to 50% in 2015 from 40% in 2014, and allocated LTI compensation to executive officers, including the NEOs, as follows:

Performance Units	Restricted Stock Units
50%	50%

Performance Units. Performance units are intended to align the NEOs’ interests with those of our stockholders, with a focus on long-term results. The performance units awarded in 2016 are structured to be paid out, if at all, in shares of McDermott common stock, cash equal to the fair market value of the shares otherwise deliverable, or any combination thereof, at the sole discretion of the Compensation Committee, at the end of a three-year performance period, to the extent the applicable performance goals are met. Relative return on average invested capital, or ROAIC, was used as the performance metric for the performance units granted in 2016, as the Compensation Committee believed that this metric tied specifically to our strategy of appropriately investing capital to grow the business. The number of performance units earned is determined based on both (1) our average ROAIC, and (2) our relative ROAIC improvement as compared to a competitor peer group comprised of both domestic and international peers, in each case over the three-year performance period. Based on this performance, up to 200% of a participant’s target award may be earned, with earned awards between the amounts shown calculated by linear interpolation. We compute McDermott’s ROAIC improvement by subtracting McDermott’s 2015 ROAIC from the three-year performance period average ROAIC. Similar calculations are done for each member of the competitor peer group, following which the median competitor peer group ROAIC improvement is calculated. The amount by which McDermott’s ROAIC improvement exceeds the competitor peer group median ROAIC improvement determines whether the threshold, target or maximum earned award is achieved.

		MDR 3-Year Average ROAIC		< 6%		≥ 6% and < 10%		≥ 10%
Performance Level		Amount by which MDR ROAIC Improvement Exceeds Competitor Peer Group Median ROAIC Improvement		Earned Award		Earned Award		Earned Award
Maximum		³ 6%		50%		200%		200%
Target		2%		50%		100%		100%
Threshold		0%		50%		50%		50%
		< 0%		0%		0%		50%

Restricted Stock Units. Restricted stock units, or RSUs, are intended to promote the retention of employees, including the NEOs. The RSUs granted in 2016 generally vest in one-third increments on the first, second and third anniversaries of the grant date. The RSUs may be paid out in shares of McDermott common stock, cash equal to the fair market value of the shares otherwise deliverable, or any combination thereof, at the sole discretion of the Compensation Committee.

2016 NEO Compensation

For 2016 NEO compensation, the Compensation Committee provided:

●	No increases in annual base salaries.
●	No increases in annual target bonus awards. As a result of McDermott’s 2016 financial performance, each NEO was eligible to earn 1.0x of his or her target EICP award, subject to adjustment by the Compensation Committee based on his or her achievement of individual performance goals.
●	The same number of units to participants in our LTI program as awarded in 2015, other than for those NEOs whose target LTI awards were adjusted in 2016. Due to the decrease in the price of McDermott stock as of the grant date for the 2016 annual LTI awards, as compared to the grant date for the 2015 annual LTI awards, this resulted in a year over year decrease in the grant date fair value of LTI awarded to the NEOs, with the exception of Messrs. Spence and Kennefick, who each received an increase to the target value of their LTI award for 2016. See “Sizing Long-Term Incentive Compensation and Timing of Equity Grants” below for further explanation of how the size of the 2016 LTI awards was determined.

The compensation of each NEO is discussed in more detail on the following pages. 

	McDermott Tenure: 3 years 6 months		DAVID DICKSON President and Chief Executive Officer
			2016 Target Total Direct Compensation
			Element	2015 Target Compensation ($)		2016 Target Compensation ($)		2016 Percentage of Target TDC
			Annual Base Salary	850,000		850,000		15%
			Annual Incentive (% of Salary)	100%		100%		15%
			Long-Term Incentive	5,000,000		4,000,000		70%
			Target TDC	6,700,000		5,700,000		100%

Annual Incentive – In February 2016, the Compensation Committee approved the following individual performance goals as a component of Mr. Dickson’s 2016 EICP award:

●	Financial – Deliver financial performance in line with forecast, with a focus on continuing to build backlog, and deliver cost savings under McDermott’s Additional Overhead Reduction initiative
●	Strategic – Evaluate and propose to the Board any changes to McDermott’s strategy and vision for both near-term and long-term objectives
●	QHSES – Continue focus on quality, health, safety, environment and security, or QHSES, statistics, with increased focus on the cost of non-quality and further development of McDermott’s Taking the Lead initiative
●	Relationships – Continue development of relationships with customers, potential partners, the investment community, governments and banks
●	Internal Organization – Continue development of effectiveness and efficiency of internal organization, and continued enhancement of processes for talent management and succession planning

The Governance Committee’s assessment of these individual performance goals considered McDermott’s continued financial and operational performance improvements during 2016. Notably, McDermott’s 2016 financial results reflected TSR of 120%, revenues of $2.6 billion, operating income of $142.3 million and order intake (including change orders) of $2.7 billion, which resulted in year-end backlog of $4.3 billion. These results reflect continued, significant improvements since Mr. Dickson was elected as President and Chief Executive Officer in 2013, and were achieved despite the difficult, “lower for longer” oil and gas market. Additionally, under his oversight McDermott’s QHSES performance has continued on a positive trend with peer leading safety statistics, increased focus on the cost of non-quality and the deployment of McDermott’s Taking the Lead initiative, designed to promote consistency in quality, safety and performance across the globe as well as operating in an environmentally conscious and socially responsible manner. During 2016, Mr. Dickson also continued improving relationships with customers, potential joint venture or consortium counterparties, the investment community, governments and banks. Finally, following significant executive management changes in prior years, in 2016 Mr. Dickson was focused on building and optimizing the executive management team as required for achievement of McDermott’s operating strategy, while improving talent management and succession planning for key roles.

In consideration of the Governance Committee’s assessment of Mr. Dickson’s achievement of his individual performance goals as discussed above, the Compensation Committee awarded Mr. Dickson a final EICP award of $1,190,000.

Long-Term Incentive – Mr. Dickson’s 2016 target LTI award was decreased from his 2015 award, with his 2016 target award returned to the amount of his 2014 target LTI award following the increase received in 2015.

Executive Compensation

Steve Allen

Mr. Allen served as McDermott’s Senior Vice President, Human Resources, until his retirement in July 2016. Mr. Allen’s 2016 target direct compensation was comprised of an annual base salary of $400,000, annual incentive target award of 70% of annual base salary earned in 2016, and long-term incentive awards with a target value of $600,000, all of which remained unchanged from 2015.

In connection with Mr. Allen’s retirement, we entered into a separation agreement with Mr. Allen providing for various compensation-related benefits in exchange for, among other things, his agreement to comply with several restrictive covenants. Under that separation agreement, Mr. Allen received: (1) a lump-sum cash payment equal to six months of his base salary; (2) an amount of 2016 bonus under the EICP based on actual performance results for 2016, prorated for the length of his 2016 service; (3) payment of an amount to fund three months of continuing health insurance coverage under the Consolidated Omnibus Reconciliation Act; and (4) accrued but unutilized vacation pay.

Additionally, Mr. Allen received the following relating to his outstanding equity awards under the McDermott International, Inc. 2009 Long-Term Incentive Plan (the “2009 LTIP”) and the 2014 LTIP: (1) each then outstanding portion of his March 6, 2014 RSU award and March 5, 2015 RSU award, and 50% of the currently outstanding portion of his February 26, 2016 RSU award, which would, absent his retirement, have remained outstanding and continued to vest through March 15, 2017 would, subject to certain conditions, vest and be settled on the date such award would otherwise be settled in accordance with the terms of the 2009 LTIP of 2014 LTIP, as applicable, and the applicable grant agreement; (2) each then outstanding portion of his May 12, 2014 RSU award which would, absent his retirement, have remained outstanding and continued to vest through May 15, 2017 would, subject to certain conditions, vest and be settled on the date such award would otherwise be settled in accordance with the terms of the 2014 LTIP and the applicable grant agreement; (3) each then outstanding portion of his May 12, 2014 award of performance shares which would, absent his retirement, have remained outstanding and continue to vest through May 15, 2017 would, subject to certain conditions, vest and be settled in accordance with the terms of the 2014 LTIP and applicable grant agreement, with the number of performance shares that would otherwise vest and settle prorated based on the number of days beginning on January 1, 2014 and ending on July 1, 2016 relative to the total number of days in the performance period; and (4) each then outstanding portion of his March 5, 2015 award of performance shares which would, absent his retirement, have remained outstanding and continued to vest through March 15, 2018 would, subject to certain conditions, vest and be settled on the date such award would otherwise be settled in accordance with the terms of the 2014 LTIP and applicable grant agreement, with the number of performance shares that would otherwise vest and settle prorated based on the number of days beginning on January 1, 2015 and ending on July 1, 2016 related to the total number of days in the performance period. All other outstanding equity and performance-based awards previously granted to Mr. Allen were forfeited at the time of his retirement. Mr. Allen’s benefits under our Director and Executive Deferred Compensation Plan became fully vested as of the date of his retirement, and those benefits are to be paid in accordance with the terms of that plan.

2016 Other Compensation Elements

Perquisites

In 2016, our Compensation Committee revised its approach with respect to perquisites, and provided for financial planning services and an executive physical to be reimbursed to the participant or paid directly to the participant’s provider of choice, in a combined amount not to exceed $20,000, rather than providing an allowance to be used for a company-required physical and any other purpose determined by the participant, as in recent years. No other perquisites were available to the participants in the perquisite program, with the exception of any company-required spousal travel for (1) the Chief Executive Officer, and (2) the remaining participants, as approved by the Chief Executive Officer. There were no reimbursements to any perquisite program participants for company-required spousal travel in 2016.

Additionally, and consistent with our past practice, we may provide a gross-up for any imputed income related to such company-required spousal travel, but only when the presence of the spouse is related to the underlying business purpose of the trip. There was no company-required spousal travel in 2016, and no imputed income or gross-ups were provided for any such company-required spousal travel in 2016. We also may provide our NEOs with a tax gross-up on any relocation-related expense reimbursements that may be subject to tax.

Expatriate Benefits

McDermott provides benefits to our expatriate employees, which benefits are designed to relocate and support employees who are sent on an assignment outside of their home country. Expatriate benefits generally include an expatriate premium equal to 10% of the employee’s base salary, a hardship premium in certain countries, a housing allowance (or company provided housing in certain locations), transportation allowance (or company provided transportation in certain locations), a cost of living differential, where applicable, a vacation allowance based on the cost of an economy plane ticket to the employee’s home location, company paid education for approved dependents in locations where public education is not an option and a tax equalization program. Following Mr. Kennefick’s relocation to Houston in November 2015,

46    2017 Proxy Statement

Table of Contents

McDermott continued to pay the cost of education for his dependents through June 2016, and also provided a tax gross-up on that cost.

Under McDermott’s tax equalization program, we ensure that expatriate employees are subject to substantially the same income tax liability as they would have paid had they lived and worked in the United States. Each expatriate employee is responsible for a hypothetical US income tax liability based on an estimate of the expatriate’s anticipated US income tax liability on their base compensation. Under the program, McDermott is responsible for any home country tax and assignment country taxes (if applicable) in excess of that amount based on the expatriate’s full compensation, including any foreign allowances. Mr. Austin participated in expatriate benefits during 2016, as Mr. Austin is a United States citizen based in Dubai.

Defined Contribution Plans

We provide retirement benefits for most of our U.S. based employees, including our U.S. based NEOs, through sponsorship of the McDermott Thrift Plan, a qualified defined contribution 401(k) plan, which we refer to as our “Thrift Plan.” We provide retirement benefits for our non-U.S. expatriate employees through sponsorship of a global defined contribution plan, which we refer to as the “McDermott Global Defined Contribution Plan.”

Retirement and Excess Plans

We do not provide defined benefit pension plans to any of our NEOs, with the exception of Ms. Hinrichs and Mr. Kennefick, who were participants in our now closed and frozen retirement and excess plans. Ms. Hinrichs and Mr. Kennefick were eligible for participation under the McDermott (U.S.) Retirement Plan (the “U.S. Retirement Plan”) before it was closed to new participants in 2006. Benefit accruals under the U.S. Retirement Plan were frozen altogether in 2010. Ms. Hinrichs is also a participant in our unfunded, nonqualified excess retirement plan (the “U.S. Excess Plan”), under which benefits have been frozen since 2010. This plan covers a small group of highly compensated employees whose ultimate benefits under the U.S. Retirement Plan are reduced by Internal Revenue Code limits on the amount of benefits which may be provided under qualified plans and the amount of compensation which may be taken into account in computing benefits under qualified plans.

See the “Pension Benefits” table under “Executive Compensation Tables” below for more information regarding the U.S. Retirement Plan, the U.S. Excess Plan and the J. Ray McDermott, S.A. Third Country National Employees Pension Plan, or the TCN Plan, which provides retirement benefits for certain of our current and former foreign employees.

Deferred Compensation Plan

The McDermott International, Inc. Director and Executive Deferred Compensation Plan, or the DCP, is a defined contribution supplemental executive retirement plan established by our Board and the Compensation Committee to help maintain the competitiveness of our post-employment compensation as compared to our market. The DCP is an unfunded, nonqualified plan that provides each participant in the plan with benefits based on the participant’s notional account balance at the time of retirement or termination. Under the DCP, on an annual basis, the Compensation Committee has the discretion to credit a specified participant’s notional account with an amount equal to a percentage of the participant’s prior-year base salary and annual bonus paid in the prior year. We refer to such credit as a “Company Contribution.” In 2016, Messrs. Dickson, Spence, Kennefick, Allen and Ms. Hinrichs were participants in the DCP and their respective accounts in the DCP received a Company Contribution in an amount equal to 5% of the sum of their respective base salaries paid in 2015 and 2014 bonus paid in 2015. Mr. Austin was not a participant in the DCP in 2016.

The Compensation Committee has designated deemed mutual fund investments to serve as indices for the purpose of determining notional investment gains and losses to each participant’s account for any Company Contribution or participant-elected deferrals. Each participant allocates any Company Contributions and deferrals among the various deemed investments. DCP benefits are based on the participant’s vested notional account balance at the time of retirement or termination. Please see the “Nonqualified Deferred Compensation” table and accompanying narrative below for more information about the DCP and Company Contributions to DCP accounts.

Employment Agreements

Except for change in control agreements described below, we do not currently have any employment agreements with any of our NEOs relating to ongoing employment. Mr. Austin has an employment agreement related to his status as an expatriate employee, which sets forth the expatriate benefits as discussed above under “Expatriate Benefits.” This employment agreement does not provide for any specified term of employment, and the terms of the agreement are generally consistent with those of employment agreements entered into with various other McDermott expatriate employees.

Change in Control Agreements

We believe change in control agreements for executive officers are common within our industry, and our Board and the Compensation Committee believe that providing these agreements to our NEOs protects stockholders’ interests by helping to assure management continuity and focus through and beyond a change in control. Accordingly, the Compensation Committee has offered change in control agreements to key senior executives since 2005. Our change in control agreements contain what is commonly referred to as a “double trigger,”

McDermott International, Inc.    47

Table of Contents

Executive Compensation

that is, they provide benefits only upon an involuntary termination or constructive termination of the executive officer within one year following a change in control. The change in control agreements for our NEOs generally provide a cash severance payment of a multiple of the sum of the NEO’s annual base salary and target EICP, as set forth below, and a pro-rated bonus payment under the EICP.

NEO	Multiple of Base Salary + Target EICP
Mr. Dickson	2.5x
Mr. Spence	2.0x
Mr. Austin	1.0x
Ms. Hinrichs	2.0x
Mr. Kennefick	2.0x

In addition, upon a change in control, each such officer would become fully vested in any outstanding and unvested equity-based awards and his or her respective account balance in the DCP.

The change in control agreements: (1) do not provide for excise tax gross-ups; (2) require the applicable officer’s execution of a release prior to payment of certain benefits; and (3) provide for the potential reduction in payments to an applicable officer in order to avoid excise taxes. Additionally, the change in control agreements with Messrs. Austin and Kennefick are scheduled to expire on March 15, 2019. See the “Potential Payments Upon Termination or Change in Control” table under “Compensation of Executive Officers” below and the accompanying disclosures for more information regarding the change in control agreements with our NEOs, as well as other plans and arrangements that have different trigger mechanisms that relate to a change in control.

Other Compensation Policies and Practices

Sizing Long-Term Incentive Compensation and Timing of Equity Grants

The Compensation Committee generally determines the size of equity-based grants as a dollar value, rather than granting a targeted number of shares or units, with each target value generally set within market range. To determine the number of restricted stock units and performance shares or units granted, the target value of long-term incentive compensation is divided by the fair market value of the applicable component of equity.

For purposes of determining 2016 awards, the Committee sought to ensure that award recipients did not receive larger share awards due solely to the decline in stock price during the preceding year. Accordingly, in February 2016, the Committee approved 2016 LTI award opportunities for the NEOs, with the number of units to be awarded based on McDermott’s stock price on March 5, 2015 (the date of 2015 LTI awards). Due to the decrease in the price of McDermott stock as of the grant date for the 2016 annual LTI awards, as compared to the grant date for the 2015 annual LTI awards, there was a year over year decrease in the grant date fair value of LTI awarded to the NEOs, with the exception of Messrs. Spence and Kennefick, who received increases to the target value of their LTI awards for 2016.

To avoid timing equity grants ahead of the release of material nonpublic information, the Compensation Committee generally grants equity awards effective as of the first day of the open trading window following the meeting at which the grants are approved, which open window period generally begins on the third NYSE trading day following the filing of our annual report on Form 10-K or quarterly report on Form 10-Q with the SEC.

Stock Ownership Guidelines

To assist with the alignment of the interests of directors, executive officers and stockholders, we believe our directors and officers should have a significant financial stake in McDermott. To further that goal, we have adopted stock ownership guidelines requiring generally that our nonemployee directors and employees who are members of McDermott’s EXCOM maintain a minimum ownership interest in McDermott. The EXCOM includes all of the NEOs. The ownership requirements are as follows:

Level	Base Salary or Annual Retainer Multiple
CEO	5x
Members of McDermott’s	3x
EXCOM
Nonemployee Directors	5x

Directors and officers have five years from their initial election as a director/officer or a change in position which increases the expected ownership level, whichever is later, to comply with the guidelines. Shares of McDermott common stock, restricted shares of McDermott common stock, restricted stock units (whether or not McDermott can settle them in cash and whether or not vested), performance shares and units (whether or not McDermott can settle them in cash and whether or not vested, but to the extent not vested, at target performance level), shares of McDermott common stock held in an employee’s Thrift Plan account and shares of McDermott common stock held in any trust in which an employee has a pecuniary interest (to the extent the employee has investment control over such shares) are all counted towards compliance with the stock ownership guidelines. Further,

48    2017 Proxy Statement

---

Table of Contents

each director and officer subject to the stock ownership guidelines has the ability to certify his or her ownership at any time after reaching compliance with the required ownership level, following which such director or officer is not required to accumulate any additional McDermott securities, so long as he or she retains the number of securities held on the certification date, regardless of any subsequent changes in the market price of shares of McDermott common stock. All directors and NEOs currently meet or exceed their ownership requirement or are within the five-year period to achieve compliance.

Derivatives Trading and Hedging

McDermott’s Insider Trading Policy prohibits all directors, officers and employees, including our NEOs, from engaging in “short sales” or trading in puts, calls or other options on McDermott’s common stock. Additionally, directors, officers and employees are prohibited from engaging in hedging transactions and from holding McDermott shares in a margin account or pledging McDermott shares as collateral for a loan.

Clawback Policy

Our Compensation Committee has adopted a clawback policy, which provides that, if the consolidated financial statements of McDermott are materially restated within three years of their initial filing, and the Compensation Committee determines, in its reasonable discretion, that any current or former executive officer has engaged in intentional misconduct, and such misconduct caused or partially caused the need for such restatement, the Compensation Committee may, within 12 months after such a material restatement, require that the executive forfeit and/or return to McDermott all or a portion of the compensation vested, awarded or received under any bonus award, equity award or other award during the period subject to restatement and the 12-month period following the initial filing of the financial statements that were restated. The forfeiture and/or return of compensation under the policy would be limited to any portion that the executive officer would not have received if the consolidated financial statements had been reported properly at the time of their initial filing. The clawback policy would not apply to restatements occurring as a result of a change in control, as defined in the DCP, and the policy does not limit the ability of McDermott to pursue forfeiture or reclamation of amounts under applicable law.

Forfeiture Provisions

Additionally, consistent with our recent practice, our grant agreements for awards made in 2016 contain a forfeiture provision. In 2016, this provision provided that, in the event that, while the grantee is employed by McDermott or performing services on behalf of McDermott under any consulting agreement, the grantee is convicted of a felony or a misdemeanor involving fraud, dishonesty or moral turpitude, or the grantee engages in conduct that adversely affects or, in the sole judgment of the Compensation Committee, may reasonably be expected to adversely affect, the business reputation or economic interests of McDermott, then all rights and benefits awarded under the respective agreements are immediately forfeited, terminated and withdrawn.

How We Make Compensation Decisions

Compensation Committee

The Compensation Committee has primary responsibility for determining and approving, on an annual basis, the compensation of our CEO and other executive officers. The Compensation Committee receives information and advice from its compensation consultant as well as from our human resources department and management to assist in compensation determinations.

Compensation Consultant

Pay Governance LLC, or “Pay Governance,” has been engaged by our Compensation Committee to serve as its consultant on executive compensation and benefits matters since November 2010. Pay Governance provides advice and analysis to the Compensation Committee on the design, structure and level of executive and director compensation, and, when requested by the Compensation Committee, attends meetings of the Compensation Committee and participates in executive sessions without members of management present. Pay Governance reports directly to the Compensation Committee, and the Compensation Committee reviews, on an annual basis, Pay Governance’s performance and provides Pay Governance with direct feedback on its performance. When requested by the Governance Committee, Pay Governance attends meetings of the Governance Committee with respect to nonemployee director compensation.

During 2016, Pay Governance did not perform any services for McDermott other than as described above. In January 2017, our Compensation Committee assessed whether the work performed by Pay Governance during 2016 raised any conflict of interest and determined that Pay Governance’s work performed for the Compensation Committee raised no conflict of interest.

Executive Compensation

Role of CEO and Management

While the Compensation Committee has the responsibility to approve and monitor all compensation for our executive officers, management plays an important role in determining executive compensation. Management, at the request of the Compensation Committee, recommends financial goals that drive the business and works with Pay Governance to analyze competitive market data and to recommend compensation levels for our executive officers other than our CEO. Our CEO likewise assists the Compensation Committee by providing his evaluation of the performance of our other executive officers and recommending compensation for those officers, including adjustments to their annual incentive compensation, based on individual performance.

Defining Market Range Compensation – 2016 Benchmarking and Peer Groups

To identify median compensation for each element of total direct compensation, the Compensation Committee relies on “benchmarking.” This involves reviewing the compensation of our NEOs relative to the compensation paid to similarly situated executives at companies we consider our peers. As a result, the annual base salary, target annual incentive compensation and target LTI compensation for each of the NEOs is benchmarked. However, the specific performance metrics and performance levels used within elements of annual and long-term compensation are designed for the principal purpose of supporting our strategic and financial goals and driving the creation of stockholder value, and, as a result, generally are not benchmarked.

Proxy Peer Group

It is the Compensation Committee’s practice to periodically review and consider the individual companies used for benchmarking purposes. The Compensation Committee believes that identification of peers using a broad industry sector code is inadequate and does not establish similarity of operations and business models, nor identify historical competitors for managerial talent – factors the Compensation Committee considers in the selection of companies for benchmarking purposes. Therefore, the Compensation Committee considers the revenues and market capitalization of the component companies. In this CD&A, we refer to the peer group as the “Proxy Peer Group.” Market data from the Proxy Peer Group was reflective of 2013 compensation, as reported in the 2014 proxy statements of the companies in the Proxy Peer Group, and was not size-adjusted, although the Compensation Committee was aware of these differences when making individual pay decisions. Market data utilized for 2016 compensation decisions was not refreshed from the data provided by Pay Governance in 2015, given the Compensation Committee’s expectation that there would be limited to no increases in elements of target direct compensation in 2016. The component companies of the Proxy Peer Group are as follows:

Archrock, Inc.	KBR, Inc.
Cameron International Corporation	Noble Corporation plc
Chicago Bridge & Iron Company N.V.	Oceaneering International, Inc.
Dresser-Rand Group, Inc.	Oil States International, Inc.
FMC Technologies, Inc.	Superior Energy Services, Inc.
Helix Energy Solutions Group, Inc.	Tidewater Inc.
Jacobs Engineering Group, Inc.

These Proxy Peer Group companies are the same as the Proxy Peer Group utilized in 2015, except that the Proxy Peer Group for 2016 did not include Foster Wheeler AG, which was acquired by AMEC plc in November 2014. Archrock, Inc. changed its name from Exterran Holdings, Inc. after its spin-off of a new publicly held company named Exterran Corporation.

Survey Peer Group

Pay Governance also utilized market data based on a set of 78 companies in similar industries which participate in Towers Watson surveys (the “Survey Peer Group”). The Survey Peer Group is intended to provide a reference point for pay levels within similar industries, and is used as a secondary reference for Messrs. Dickson and Spence and Ms. Hinrichs, and a primary reference for Messrs. Allen, Austin and Kennefick. Aside from screening companies on the basis of their industry classifications, no further refinements or judgments were applied in the identification of companies within the sample. Market data from the Survey Peer Group represents 2014 compensation as reported to the survey and, when possible, was size adjusted. Corporate positions were evaluated based on average revenues of $3.3 billion, and business unit positions were evaluated based on their respective revenue levels. The component companies of the Survey Peer Group are as follows:

Anadarko Petroleum Corporation	HNTB Corporation	PolyOne Corporation
Apache Corporation	Holly Frontier Corporation	PulteGroup, Inc.

(1)	These columns reflect the threshold, target and maximum payout opportunities under the Executive Incentive Compensation Plan, or EICP.
	On February 26, 2016, our Compensation Committee established target EICP awards expressed as a percentage of the NEO’s 2016 annual base salary earned, as follows: Mr. Dickson – 100%, Mr. Spence – 70%, Mr. Austin – 50%, Ms. Hinrichs – 70%, Mr. Kennefick – 50%, and Mr. Allen – 70%. The target amounts shown for Messrs. Dickson, Spence, Kennefick, and Allen and Ms. Hinrichs were computed by multiplying their annual base salaries by their target award percentage. For all of the NEOs, the threshold amounts are equal to 50% of the respective target amounts and the maximum amounts are equal to 200% of the respective target amounts. See “Compensation Discussion and Analysis – What We Pay and Why: Elements of Total Direct Compensation – Annual Incentive” and “Compensation Discussion and Analysis – 2016 NEO Compensation” for a detailed description of the EICP and discussions regarding the determinations made with respect to the 2016 EICP awards.
(2)	These columns reflect the target, threshold and maximum payout opportunities of 2016 grants of performance units under the 2014 LTIP. Each grant represents the right to receive the value of one share of McDermott common stock for each vested performance unit, paid in shares of McDermott common stock, cash equal to the fair market value of the shares otherwise deliverable, or any combination thereof, in the sole discretion of the Compensation Committee. The amount of performance units that vest, if any, will be based on McDermott’s relative ROAIC improvement as compared to a competitor peer group over a three-year measurement period (January 1, 2016 – December 31, 2018). If the threshold performance goal is achieved, a number of performance units between 50% and 200% of the target award may be earned, depending on the three-year aggregate relative ROAIC performance. See “Compensation Discussion and Analysis – What We Pay and Why: Elements of Total Direct Compensation – Long-Term Incentives” and “2016 NEO Compensation” for a detailed description of the performance units awarded in 2016.
(3)	This column reflects grants of restricted stock units under the 2014 LTIP. The restricted stock units are generally scheduled to vest in one-third increments on the first, second and third anniversaries of the date of grant. Each restricted stock unit represents the right to receive one share of McDermott common stock, cash equal to the fair market value of the share otherwise deliverable, or any combination thereof, in the sole discretion of the Compensation Committee.
(4)	This column reflects the full grant date fair values of the equity awards computed in accordance with FASB ASC Topic 718. Grant date fair values are determined using the closing price of our common stock on the date of grant, as reported on the NYSE. For more information regarding the compensation expense related to 2016 awards, see Note 14 to our consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2016.

Pension Benefits

The following Pension Benefits table shows the present value of accumulated benefits payable to the only two of our NEOs who are entitled to benefits under the defined benefit pension plans that we sponsor. All benefits under the defined benefit pension plans that we sponsor are frozen.

Name		Plan Name		Number of Years Credited Service		Present Value of Accumulated Benefit ($)		Payments During 2016 ($)

Mr. Kennefick		U.S. Retirement Plan(1)		9.583		225,902		0
Mr. Allen		N/A		N/A		N/A		N/A

(1)	The present value of accumulated benefits reflected above for the U.S. Retirement Plan and the U.S. Excess Plan is based on a 4.1% discount rate and the RP2014 mortality table for annuitants projected with generational mortality improvement scale MP2016.

U.S. Retirement Plan

We refer to our qualified defined benefit pension plan as the U.S. Retirement Plan. Ms. Hinrichs and Mr. Kennefick are the only NEOs who participate in the U.S. Retirement Plan, which plan has been frozen since 2006 and under which they are accruing no additional benefits. The U.S. Retirement Plan is funded by a trust, and includes provisions related to eligibility, participation and benefit formulas for applicable employees.

Under the U.S. Retirement Plan, normal retirement is the later of (1) age 65 or (2) the fifth anniversary of the date an employee becomes a participant. The normal form of payment is a single-life annuity or a 50% joint and survivor annuity, depending on the employee’s marital status when payments are scheduled to begin. Early retirement eligibility and benefits under the Retirement Plan depend on the employee’s date of hire and age. For employees hired on or after April 1, 1998 (including Ms. Hinrichs and Mr. Kennefick), an employee is eligible for early retirement upon the latter of completing at least 15 years of continuous service and attaining the age of 55. Early retirement benefits are based on the same formula as normal retirement, but the pension benefit is generally reduced 0.4% for each month that benefits commence before age 62. Ms. Hinrichs is eligible for early retirement under the U.S. Retirement Plan.

Ms. Hinrichs’ and Mr. Kennefick’s benefits under the U.S. Retirement Plan are calculated as follows: 1.2% of final average monthly compensation as of June 30, 2010 up to the Social Security limit times credited service up to 35 years, plus 1.65% of final average monthly compensation as of June 30, 2010 in excess of the Social Security limit times credited service up to 35 years. Final average monthly compensation excludes bonuses and commissions.

U.S. Excess Plan

We refer to our nonqualified pension plan as the U.S. Excess Plan. Ms. Hinrichs is the only NEO who participates in the U.S. Excess Plan, which plan has been frozen since 2006 and under which she is accruing no additional benefits. To the extent benefits payable under the U.S. Retirement Plan are limited by Section 415(b) or 401(a)(17) of the U.S. Internal Revenue Code, pension benefits will be paid under the terms of the U.S. Excess Plan. Because benefits entitlement under the U.S. Excess Plan and the U.S. Retirement Plan are linked, benefits under the U.S. Excess Plan have been frozen since 2006, when benefit accruals under the U.S. Retirement Plan were frozen.

TCN Pension Plan

We refer to our defined benefit pension plan for certain non-U.S. employees as the TCN Pension Plan. There are no NEO participants in the TCN Pension Plan, which is now frozen. The TCN Pension Plan is funded by a trust, and includes provisions related to eligibility, participation and benefit formulas for employees who were employed by certain of our non-U.S. subsidiaries.

Potential Payments Upon Termination or Change in Control

The following tables show potential payments to our NEOs under existing contracts, agreements, plans or arrangements, whether written or unwritten, for various scenarios under which a payment would be due (assuming each is applicable) involving a change in control or termination of employment of each of our NEOs, assuming a December 31, 2016 termination date and, where applicable, using the closing price of our common stock of $7.39 as of December 30, 2016 (as reported on the NYSE). These tables do not reflect amounts that would be payable to the Continuing NEOs pursuant to benefits or awards that are already vested.

The amounts reported in the below tables for stock options, restricted stock, restricted stock units and performance shares or performance units represent the value of unvested and accelerated shares or units, as applicable, calculated by:

●	for stock options: multiplying the number of accelerated options by the difference between the exercise price and $7.39 (the closing price of our common stock on December 30, 2016, as reported on the NYSE); and
●	for restricted stock, restricted stock units and performance shares or performance units: multiplying the number of accelerated shares or units by $7.39 (the closing price of our common stock on December 30, 2016, as reported on the NYSE).

Mr. Allen resigned from his position as Senior Vice President, Human Resources in July 2016. In connection with Mr. Allen’s resignation, we entered into a separation agreement with Mr. Allen providing for various compensation-related benefits in exchange for, among other things, his agreement to comply with several restrictive covenants. See page 46 of this proxy statement for information on compensation received by Mr. Allen under that separation agreement.

Estimated Value of Benefits to Be Received Upon Termination Due to Death or Disability

(1)	The amounts reported represent 60% of Mr. Dickson’s, 80% of Mr. Spence’s, and 100% of Mr. Kennefick’s DCP balance as of December 31, 2016 that would become vested on death or disability. Mr. Austin was not a participant in the DCP as of December 31, 2016. Because Ms. Hinrichs is 100% vested in her DCP balance, no additional amount would become vested on her death or disability.
(2)	Under the terms of the outstanding stock option awards held by each of the listed NEOs as of December 31, 2016, all unvested option awards would become vested and exercisable on death or disability. Due to the exercise price of the stock options outstanding and the closing price of our common stock on December 31, 2016, the aggregate value of stock options that would become vested and exercisable on death or disability for each applicable NEO would be $0.
(3)	Under the terms of the restricted stock award agreement between McDermott and Mr. Dickson, all unvested restricted stock would become vested upon Mr. Dickson’s death or disability.
(4)	Under the terms of the outstanding restricted stock unit awards held by each of the listed NEOs as of December 31, 2016, all unvested restricted stock unit awards would become vested and exercisable on his or her death or disability.
(5)	Under the terms of the outstanding 2012 performance share awards held by each of the listed NEOs as of December 31, 2016, 100% of the initial performance shares granted would vest on the third, fourth and fifth anniversary of the grant date on his or her death or disability. The number of performance shares that would vest is the number of performance shares that would have vested based on actual performance had the NEO remained employed with McDermott until the third, fourth and fifth

(1)

The salary-based severance payment made to Mr. Dickson in connection with a change in control would be a cash payment equal to 250% of the sum of his annual base salary prior to termination and his EICP target award applicable to the year in which the termination occurs. The severance payment made to Messrs. Spence and Kennefick and Ms. Hinrichs in connection with a change in control would be a cash payment equal to 200% of the sum of his or her annual base salary prior to termination and his or her EICP target award applicable to the year in which the termination occurs. The severance payment made to Mr. Austin in connection with a change in control would be a cash payment equal to the sum of his annual base salary prior to termination and his EICP target award applicable to the year in which the termination occurs.

For a hypothetical termination as of December 31, 2016, the salary-based severance payment under a change in control would have been calculated based on the following base salary and target EICP awards. See “Grants of Plan-Based Awards” above for more information on the calculation of target EICP awards.

NEO		Annual Base Salary ($)		Target EICP Award ($)
Mr. Dickson		850,000		850,000
Mr. Spence		475,000		332,500
Mr. Austin		325,000		162,500
Ms. Hinrichs		477,750		334,425
Mr. Kennefick		375,000		187,500

(2)

Each listed NEO could receive up to two EICP-based severance payments in connection with a change in control depending on the timing of the termination relative to the payment of an EICP award, as follows:

●If an EICP award for the year prior to termination is paid to other EICP participants after the date of the NEO’s termination, the NEO would be entitled to a cash payment equal to the product of the NEO’s target EICP percentage (or, if greater, the actual amount of the bonus determined under the EICP for the year prior to termination) and the NEO’s annual base salary for the applicable period. No such payment would have been due a NEO on a December 31, 2016 termination, because the 2015 EICP awards had already been paid.

●The NEO would be entitled to a prorated EICP payment based upon the NEO’s target EICP percentage for the year in which the termination occurs and the number of days in which the NEO was employed with us during that year. Based on a hypothetical December 31, 2016 termination, each NEO would have been entitled to an EICP payment equal to 100% of his or her 2016 target EICP percentage times annual base salary, calculated based on the following base salary and target EICP percentage:

NEO		Annual Base Salary ($)		Target EICP Percentage ($)
Mr. Dickson		850,000		100%
Mr. Spence		475,000		70%
Mr. Austin		325,000		50%
Ms. Hinrichs		477,750		70%
Mr. Kennefick		375,000		50%

(3)	The amounts reported represent 60% of Mr. Dickson’s, 80% of Mr. Spence’s and 100% of Mr.. Kennefick’s respective DCP balances as of December 31, 2016 that would become vested on a change in control. Mr. Austin was not a participant in the DCP as of December 31, 2016. Because Ms. Hinrichs is 100% vested in her DCP balance, no additional amount would become vested in connection with a termination of employment following a change in control. Under the Deferred Compensation Plan, a “change in control” generally occurs if:
	● a person (other than a McDermott employee benefit plan or a corporation owned by McDermott stockholders in substantially the same proportion as the ownership of McDermott voting shares) is or becomes the beneficial owner of 30% or more of the combined voting power of McDermott’s then outstanding voting stock; ● during any period of two consecutive years, individuals who at the beginning of such period constitute McDermott’s Board of Directors, and any new director whose election or nomination by McDermott’s Board was approved by at least two-thirds of the directors of McDermott’s Board then still in office who either were directors at the beginning of the period or whose election or nomination was previously approved, cease to constitute a majority of McDermott’s Board; ● a merger or consolidation of McDermott with any other corporation or entity has been completed, other than a merger or consolidation which results in the outstanding McDermott voting securities immediately prior to such merger or consolidation continuing to represent at least 50% of the combined voting power of the voting securities of McDermott or the surviving entity outstanding immediately after such merger or consolidation; ● McDermott’s stockholders approve (1) a plan of complete liquidation of McDermott; or (2) an agreement for the sale or disposition by McDermott of all or substantially all of McDermott’s assets; or ● within one year following the completion of a merger or consolidation transaction involving McDermott, (1) individuals who, at the time of execution and delivery of definitive agreements completing such transaction constituted the Board, cease for any reason (excluding death, disability or voluntary resignation) to constitute a majority of the Board; or (2) either individual, who at the first execution and delivery of definitive agreements completing the transaction, served as Chief Executive Officer or Chief Financial Officer does not, for any reason (excluding death, disability or voluntary resignation), serve as the Chief Executive Officer or Chief Financial Officer, as applicable, of McDermott, or if McDermott does not continue as a registrant with a class of equity securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, as the Chief Executive Officer or Chief Financial Officer, as applicable, of a corporation or other entity that is (A) a registrant with a class of equity securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, and (B) the surviving entity in such transaction or a parent entity of the surviving entity or McDermott following the completion of such transaction; provided, however, that a change in control would not be deemed to have occurred pursuant to this clause in the case of a merger or consolidation which results in the voting securities of McDermott outstanding immediately prior to the completion of the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 55% of the combined voting power of the voting securities of the McDermott or the surviving entity outstanding immediately after such merger or consolidation.
(4)	Under the terms of the stock option, restricted stock and the 2013, 2014 and 2015 restricted stock unit awards outstanding, all unvested stock options would become vested and exercisable and all unvested restricted stock and restricted stock units would become vested on a change in control, regardless of whether there is a subsequent termination of employment. Under the terms of the 2016 restricted stock unit awards outstanding, all unvested restricted stock units would become vested on a change in control, regardless of whether there is a subsequent termination of employment, only if the awards are not assumed in the transaction. Due to the exercise price of the stock options outstanding for our NEOs and the closing price of our common stock on the NYSE on December 31, 2016, the aggregate value of stock options that would become vested and exercisable on a change in control would be $0. Under the terms of the 2012, 2014 and 2015 performance share or performance unit awards outstanding, the greater of (1) 100% of the initial performance shares or performance units granted, or (2) the vested percentage of initial performance shares or performance units determined in accordance with the grant agreement would become vested on a change in control, regardless of whether there is a subsequent termination of employment. Under the terms of the 2016 performance unit awards outstanding, the greater of (1) target level, or (2) the actual performance level measured through the date the change in control becomes effective as determined in accordance with the grant agreement would become vested on a change in control, regardless of whether there is a subsequent termination of employment, only if the awards are not

If the 2016 performance unit awards are assumed in a change in control, such awards would only vest on a subsequent termination of employment by the employer without cause or by the executive for good reason. Under the 2009 LTIP, a “change in control” generally occurs under the same circumstances described above with respect to our Deferred Compensation Plan. Under the 2014 LTIP, a “change in control” generally occurs under the same circumstances described in the first three bullets in note (3) above with respect to our Deferred Compensation Plan, as well as on the occurrence of the below circumstances: ● McDermott’s stockholders approve a plan of complete liquidation of McDermott; ● the consummation of a sale or disposition by McDermott of all or substantially all of McDermott’s assets other than to an entity that is under common control with McDermott or to an entity for which at least fifty percent (50%) of the combined voting power of its voting securities outstanding immediately after such sale or disposition are owned or controlled by the stockholders of McDermott immediately prior to such sale or disposition; or ● within one year following the completion of a merger or consolidation transaction involving McDermott, (1) individuals who, at the time of execution and delivery of definitive agreements relating to such transaction constituted the Board, cease for any reason (excluding death, disability or voluntary resignation) to constitute a majority of the Board; or (2) the individual, who at the first execution and delivery of definitive agreements relating to the transaction, served as Chief Executive Officer does not, for any reason (excluding death, disability or voluntary resignation), serve as the Chief Executive Officer of McDermott, or if McDermott does not continue as a registrant with a class of equity securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, as the Chief Executive Officer of a corporation or other entity that is (A) a registrant with a class of equity securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, and (B) the surviving entity in such transaction or a parent entity of the surviving entity or McDermott following the completion of such transaction; provided, however, that a change in control would not be deemed to have occurred pursuant to this clause in the case of a merger or consolidation which results in the voting securities of McDermott outstanding immediately prior to the completion of the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 55% of the combined voting power of the voting securities of the McDermott or the surviving entity outstanding immediately after such merger or consolidation. Under the 2016 LTIP, a “change in control” generally occurs under the same circumstances described in the first three bullets in note (3) above with respect to our Deferred Compensation Plan, and under the same circumstances described in the first two bullets above with respect to our 2014 LTIP, as well as on the occurrence of the below circumstance: ● within one year following the consummation of a merger or consolidation transaction involving the Company (whether as a constituent corporation, the acquiror, the direct or indirect parent entity of the acquiror, the entity being acquired, or the direct or indirect parent entity of the entity being acquired), as a result of which the voting securities of the Company outstanding immediately prior thereto continue to represent more than fifty percent (50%) but less than fifty-five percent (55%) of the combined voting power of the voting securities of the Company or the surviving entity outstanding immediately after such merger or consolidation (a “Merger of Equals”): (i) individuals who, at the time of the execution and delivery of the definitive agreement pursuant to which such transaction has been consummated by the parties thereto (a “Definitive Transaction Agreement”) (or, if there are multiple such agreements relating to such Merger of Equals, the first time of execution and delivery by the parties to any such agreement) (the “Execution Time”), constituted the Board cease, for any reason (excluding death, disability or voluntary resignation but including any such voluntary resignation effected in accordance with any Definitive Transaction Agreement), to constitute a majority of the Board; or (ii) the individual who, at the Execution Time, served as the Chief Executive Officer of the Company does not, for any reason (excluding as a result of death, disability or voluntary termination but including any such voluntary termination effected in accordance with any Definitive Transaction Agreement), serve as the Chief Executive Officer of the Company or, if the Company does not continue as a registrant with a class of equity securities registered pursuant to Section 12(b) of the Exchange Act, as the Chief Executive Officer of a corporation or other entity that is (A) a registrant with a class of equity securities registered pursuant to Section 12(b) of the Exchange Act and (B) the surviving entity in such Merger of Equals or a direct or indirect parent entity of the surviving entity or the Company following the consummation of such Merger of Equals. The amounts reported in the chart above represent a total of 100% of the initial performance shares or units granted for the 2012, 2015 and 2016 awards and a total of 150% of the initial performance shares granted for the 2014 awards.

FREQUENCY OF THE ADVISORY VOTE ON EXECUTIVE COMPENSATION

Item 3 – Advisory Vote on Frequency of Advisory Votes on Executive Compensation

As required by Section 14A(a)(2) of the Exchange Act, we are providing our stockholders with the opportunity to vote, on a non-binding, advisory basis, on how frequently we should seek future advisory votes on the compensation of our named executive officers, as disclosed in accordance with disclosure rules established by the SEC. By voting with respect to this proposal, stockholders may indicate whether they would prefer that we conduct future advisory votes on the compensation of our named executive officers once every one, two or three years. Our Board believes having an advisory vote on our named executive officer compensation every year, rather than every two or three years, is the best practice, in that it provides stockholders the opportunity to provide us their views on our compensation programs, as they potentially change to meet market and McDermott specific needs, on an annual basis.

For the reasons discussed above, the Board of Directors recommends that stockholders vote to hold the advisory vote on compensation of our named executive officers every year. Stockholders are not voting, however, to approve or disapprove of this particular recommendation. The proxy card provides for four choices and stockholders are entitled to vote on whether the advisory vote on compensation of our named executive officers should be held every one, two or three years, or to abstain from voting. While the result of this advisory vote on the frequency of the vote on named executive officer compensation is nonbinding, the Board of Directors plans to consider the outcome of the vote when deciding how frequently to conduct the vote on named executive officer compensation.

The Board of Directors unanimously recommends that you vote to hold the advisory vote on named executive officer compensation EVERY YEAR.

Our Board of Directors recommends that stockholders vote “FOR” holding the advisory vote on named executive officer compensation EVERY YEAR.

AUDITOR AND AUDIT COMMITTEE MATTERS

Item 4 – Ratification of Appointment of Independent Registered Public Accounting Firm for Year Ending December 31, 2017

Our Board of Directors has ratified the decision of the Audit Committee to appoint Deloitte & Touche LLP (“D&T”) to serve as the independent registered public accounting firm to audit our financial statements for the year ending December 31, 2017. Although we are not required to seek stockholder approval of this appointment, it has been our practice to do so. No determination has been made as to what action the Audit Committee or the Board of Directors would take if our stockholders fail to ratify the appointment. Even if the appointment is ratified, the Audit Committee retains discretion to appoint a new independent registered public accounting firm at any time if the Audit Committee concludes such a change would be in the best interests of McDermott. Representatives of D&T will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so and to respond to appropriate questions.

Our Board of Directors recommends that stockholders vote “FOR” the ratification of the decision of our Audit Committee to appoint Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2017. The proxy holders will vote all proxies received for approval of this proposal unless instructed otherwise. Approval of this proposal requires the affirmative vote of a majority of the outstanding shares of common stock present in person or represented by proxy and entitled to vote and actually voting on this proposal at the Annual Meeting. Because abstentions are not actual votes with respect to this proposal, they have no effect on the outcome of the vote on this proposal.

Audit Committee Report

The Board of Directors appoints an Audit Committee to review McDermott International, Inc.’s financial matters. Each member of the Audit Committee meets the independence requirements established by the NYSE. The Audit Committee is responsible for the appointment, compensation, retention and oversight of McDermott’s independent registered public accounting firm. We are also responsible for recommending to the Board that McDermott’s audited financial statements be included in its Annual Report on Form 10-K for the fiscal year.

In making our recommendation that McDermott’s financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2016, we have taken the following steps:

●	We reviewed, and discussed with McDermott’s management and D&T, McDermott’s audited consolidated balance sheet at December 31, 2016, and consolidated statements of income, comprehensive income, cash flows and stockholders’ equity for the year ended December 31, 2016.
●	We discussed with D&T, McDermott’s independent registered public accounting firm for the year ended December 31, 2016, those matters required to be discussed under the applicable standards of the Public Company Accounting Oversight Board, including information regarding the scope and results of the audit. These communications and discussions are intended to assist us in overseeing the financial reporting and disclosure process.
●	We received and reviewed the written disclosures and the letter from D&T required by applicable requirements of the Public Company Accounting Oversight Board regarding D&T’s communications with the Audit Committee concerning D&T’s independence from McDermott, and have discussed with D&T its independence from McDermott. We also considered whether the provision of non-audit services to McDermott is compatible with D&T’s independence.
●	We conducted periodic executive sessions with D&T, with no members of McDermott management present during those discussions. D&T did not identify any material audit issues, questions or discrepancies, other than those previously discussed with management, which were resolved to the satisfaction of all parties.

Auditor and Audit Committee Matters

●	We reviewed, and discussed with McDermott’s management and D&T, management’s report and D&T’s report and attestation on internal control over financial reporting, each of which was prepared in accordance with Section 404 of the Sarbanes-Oxley Act.
●	We determined that there were no former D&T employees, who previously participated in the McDermott audit, engaged in a financial reporting oversight role at McDermott.

Based on the reviews and actions described above, we recommended to the Board that McDermott’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the Securities and Exchange Commission.

Questions and Answers About the Annual Meeting of Stockholders and Voting

What is the purpose of these proxy materials?

As more fully described in the Notice, the Board of Directors of McDermott has made these materials available to you in connection with our 2017 Annual Meeting of Stockholders, which will take place on May 5, 2017 at 10:00 a.m., local time (the “Annual Meeting” or “Meeting”). We mailed the Notice to our stockholders beginning on March 24, 2017, and our proxy materials were posted on the Web site referenced in the Notice on that same date.

McDermott, on behalf of its Board of Directors, is soliciting your proxy to vote your shares at the 2017 Annual Meeting of Stockholders. We solicit proxies to give all stockholders of record an opportunity to vote on matters that will be presented at the Annual Meeting. In this proxy statement you will find information on these matters, which is provided to assist you in voting your shares.

Who will pay for the cost of this proxy solicitation?

We will bear all expenses incurred in connection with this proxy solicitation, which we expect to conduct primarily by mail. We have engaged Georgeson to assist in the solicitation for a fee that will not exceed $12,500, plus out-of-pocket expenses. In addition, our officers and regular employees may solicit your proxy by telephone, by facsimile transmission or in person, for which they will not be separately compensated. If your shares are held through a broker or other nominee (i.e., in “street name”) and you have requested printed versions of these materials, we have requested that your broker or nominee forward this proxy statement to you and obtain your voting instructions, for which we will reimburse them for reasonable out-of-pocket expenses. If your shares are held through the McDermott Thrift Plan and you have requested printed versions of these materials, the trustee of that plan has sent you this proxy statement and you can instruct the trustee on how to vote your plan shares.

Who is entitled to vote at the Annual Meeting?

Our Board of Directors selected March 13, 2017 as the record date for determining stockholders entitled to vote at the Annual Meeting. This means that if you owned McDermott common stock on the Record Date, you may vote your shares on the matters to be considered by our stockholders at the Annual Meeting.

There were 243,047,477 shares of our common stock outstanding on the Record Date. Each outstanding share of common stock entitles its holder to one vote on each matter to be acted on at the meeting.

Who may attend the Annual Meeting?

Attendance at the meeting is limited to stockholders and beneficial owners as of the record date or duly appointed proxies. No guests will be admitted, except for guests invited by McDermott. Registration will begin at 9:00 a.m., and the meeting will begin promptly at 10:00 a.m. If your shares are held in “street name” through a broker, bank, trustee or other nominee, you are a beneficial owner, and beneficial owners will need to show proof of beneficial ownership, such as a copy of a brokerage account statement, reflecting stock ownership as of the Record Date in order to be admitted to the meeting. If you are a proxy holder for a stockholder, you will need to bring a validly executed proxy naming you as the proxy holder, together with proof of record ownership of the stockholder naming you as proxy holder. Please note that you may be asked to present valid photo identification, such as a valid driver’s license or passport, when you check in for registration. No cameras, recording equipment or other electronic devices will be allowed to be brought into the meeting room by stockholders or beneficial owners.

What is the difference between holding shares as a stockholder of record and as a beneficial owner through a brokerage account or other arrangement with a holder of record?

If your shares are registered in your name with McDermott’s transfer agent and registrar, Computershare Trust Company, N.A., you are the “stockholder of record” of those shares. The Notice and the proxy materials have been provided or made available directly to you by McDermott.

If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” but not the holder of record of those shares, and the Notice and the proxy materials have been forwarded to you by your broker, bank or other holder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote your shares by using the voting instruction card or by following their instructions for voting by telephone or on the Internet.

How do I cast my vote?

Most stockholders can vote by proxy in three ways:

●	by Internet at www.proxyvote.com;
●	by telephone; or
●	by mail.

Other Information

If you are a stockholder of record, you can vote your shares in person at the Annual Meeting or vote now by giving us your proxy via Internet, telephone or mail. You may give us your proxy by following the instructions included in the Notice or, if you received a printed version of these proxy materials, in the enclosed proxy card. If you want to vote by mail but have not received a printed version of these proxy materials, you may request a full packet of proxy materials by following the instructions in the Notice. If you vote using either the telephone or the Internet, you will save us mailing expenses.

By giving us your proxy, you will be directing us how to vote your shares at the meeting. Even if you plan on attending the meeting, we urge you to vote now by giving us your proxy. This will ensure that your vote is represented at the meeting. If you do attend the meeting, you can change your vote at that time, if you then desire to do so.

If you are the beneficial owner of shares, but not the holder of record, you should refer to the instructions provided by your broker or nominee for further information. The broker or nominee that holds your shares has the authority to vote them, absent your approval, only as to matters for which they have discretionary authority under the applicable NYSE rules. Neither the election of directors, the advisory vote to approve named executive officer compensation, nor the advisory vote on the frequency of advisory votes on named executive officer compensation are considered routine matters. That means that brokers may not vote your shares with respect to those matters if you have not given your broker specific instructions as to how to vote. Please be sure to give specific voting instructions to your broker.

If you received a printed version of these proxy materials, you should have received a voting instruction form from your broker or nominee that holds your shares. For shares of which you are the beneficial owner but not the holder of record, follow the instructions contained in the Notice or voting instruction form to vote by Internet, telephone or mail. If you want to vote by mail but have not received a printed version of these proxy materials, you may request a full packet of proxy materials as instructed by the Notice. If you want to vote your shares in person at the Annual Meeting, you must obtain a valid proxy from your broker or nominee. You should contact your broker or nominee or refer to the instructions provided by your broker or nominee for further information. Additionally, the availability of telephone or Internet voting depends on the voting process used by the broker or nominee that holds your shares.

Why did I receive more than one Notice or proxy statement and proxy card or voting instruction form?

You may receive more than one Notice, proxy statement, proxy card or voting instruction form if your shares are held through more than one account (e.g., through different brokers or nominees). Each proxy card or voting instruction form only covers those shares of common stock held in the applicable account. If you hold shares in more than one account, you will have to provide voting instructions as to each of your accounts in order to vote all your shares.

What is “householding”?

SEC rules regarding the delivery of the Notice of Internet Availability of Proxy Materials, proxy statements and annual reports permit us, in specified circumstances, to deliver a single set of these materials to any address at which two or more stockholders reside. This method of delivery, often referred to as “householding,” will reduce the amount of duplicative information that stockholders receive and lower printing and mailing costs for us. Each stockholder will continue to receive a separate proxy card.

We have delivered only one Notice of Internet Availability of Proxy Materials to eligible stockholders who are the beneficial owner of shares who share an address, unless contrary instructions were received from any such stockholder prior to the mailing date. We will deliver promptly, upon written or oral request, a separate copy of the Notice of Internet Availability of Proxy Materials to a stockholder at a shared address to which a single copy of such document was delivered. Any stockholder who would like to receive a separate copy of the Notice of Internet Availability of Proxy Materials should submit this request to McDermott’s Corporate Secretary at the following address: McDermott International, Inc., 757 N. Eldridge Pkwy., Houston, Texas 77079, Attn: Corporate Secretary. Beneficial owners sharing an address who receive multiple copies of the Notice of Internet Availability of Proxy Materials and who would like to receive a single copy of such materials in the future will need to contact their broker, bank or other nominee to request that only a single copy of such document be mailed to all stockholders at the shared address in the future.

What can I do if I change my mind after I vote?

If you are a stockholder of record, you may change your vote by written notice to our Corporate Secretary, by granting a new proxy before the Annual Meeting or by voting in person at the Annual Meeting. Unless you attend the meeting and vote your shares in person, you should change your vote before the meeting using the same method (by Internet, telephone or mail) that you first used to vote your shares. That way, the inspectors of election for the meeting will be able to verify your latest vote.

If you are the beneficial owner, but not the holder of record, of shares, you should follow the instructions in the information provided by your broker or nominee to change your vote before the meeting. If you want to change your vote as to shares of which you are the beneficial owner by voting in person at the Annual Meeting, you must obtain a valid proxy from the broker or nominee that holds those shares for you.

What is a broker non-vote?

If you are a beneficial owner whose shares are held of record by a broker or other holder of record, you must instruct the broker or other holder of record how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any proposal on which the broker does not have discretionary authority to vote. This is called a “broker non-vote.” In these cases, the broker or other holder of record can include your shares as being present at the Annual Meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required under the rules of the NYSE.

For this Annual Meeting, if you are a beneficial owner whose shares are held by a broker or other holder of record, your broker or other holder of record has discretionary voting authority under NYSE rules to vote your shares on the ratification of Deloitte & Touche LLP, even if it has not received voting instructions from you. However, such holder does not have discretionary authority to vote on the election of directors, the advisory vote to approve named executive officer compensation or the advisory vote on the frequency of advisory votes on named executive officer compensation without instructions from you, in which case a broker non-vote will result and your shares will not be voted on those matters.

What is the quorum for the Annual Meeting?

The Annual Meeting will be held only if a quorum exists. The presence at the meeting, in person or by proxy, of holders of a majority of our outstanding shares of common stock as of the Record Date will constitute a quorum. If you attend the meeting or vote your shares by Internet, telephone or mail, your shares will be counted toward a quorum, even if you abstain from voting on a particular matter. Broker non-votes will be treated as present for the purpose of determining a quorum.

Which items will be voted on at the Annual Meeting?

At the Annual Meeting, we are asking you to vote on the following:

●	the election of John F. Bookout, III, David Dickson, Stephen G. Hanks, Erich Kaeser, Gary P. Luquette, William H. Schumann, III, Mary L. Shafer-Malicki and David A. Trice to our Board of Directors, each for a term of one year;
●	the advisory vote to approve named executive officer compensation;
●	the advisory vote on the frequency of advisory votes on named executive officer compensation; and
●	the ratification of our Audit Committee’s appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2017.

We are not aware of any other matters that may be presented or acted on at the Annual Meeting. If you vote by signing and returning the enclosed proxy card or using the telephone or Internet voting procedures, the individuals named as proxies on the card may vote your shares, in their discretion, on any other matter requiring a stockholder vote that comes before the meeting.

What are the Board’s voting recommendations?

For the reasons set forth in more detail previously in this proxy statement, our Board recommends a vote:

●	FOR the election of each director nominee;
●	FOR the advisory vote to approve named executive officer compensation;
●	for holding the advisory vote on named executive officer compensation EVERY YEAR; and
●	FOR the ratification of our Audit Committee’s appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2017.

What are the voting requirements to elect the Directors and to approve each of the proposals discussed in this proxy statement?

Each proposal requires the affirmative vote of a majority of our outstanding shares present in person or represented by proxy at the meeting and entitled to vote and actually voting on the matter. Because votes withheld in the election of any director, abstentions and broker non-votes are not actual votes with respect to a proposal, they will have no effect on the outcome of the vote on any proposal.

Our Corporate Governance Guidelines provide that, in an uncontested election of directors, the Board expects any incumbent director nominee who does not receive “FOR” votes by a majority of shares present in person or by proxy and entitled to vote and either voting “FOR” or registering a decision to withhold a vote with respect to the election of such director to promptly tender his or her resignation to the Governance Committee, subject to acceptance by our Board. Any shares subject to broker non-votes shall not be considered in making any determination pursuant to the immediately preceding sentence. The Governance Committee will then make a recommendation to the Board with respect to the director nominee’s resignation and the Board will consider the recommendation and take appropriate action within 120 days from the date of the certification of the election results.

What happens if I do not specify a choice for a proposal when returning a proxy or do not cast my vote?

You should specify your choice for each proposal on your proxy card or voting instruction form. Shares represented by proxies will be voted in accordance with the instructions given by the stockholders.

If you are a stockholder of record and your proxy card is signed and returned without voting instructions, it will be voted according to the recommendations of our Board. If

Other Information

you do not return your proxy card or cast your vote, no votes will be cast on your behalf on any of the items of business at the Annual Meeting.

If you are the beneficial owner, but not the holder of record, of shares and fail to provide voting instructions, your broker or other holder of record is permitted to vote your shares on the ratification of Deloitte as our independent registered public accounting firm. However, absent instructions from you, your broker or other holder of record may not vote on the election of directors, the advisory vote to approve named executive officer compensation, or the advisory vote on the frequency of advisory votes on named executive officer compensation, and no votes will be cast on your behalf for those matters.

Is my vote confidential?

All voted proxies and ballots will be handled in a manner intended to protect your voting privacy as a stockholder. Your vote will not be disclosed except: 

●	to meet any legal requirements;
●	in limited circumstances such as a proxy contest in opposition to our Board of Directors;
●	to permit independent inspectors of election to tabulate and certify your vote; or
●	to respond to your written comments on your proxy card.

Stockholders’ Proposals

Any stockholder who wishes to have a qualified proposal considered for inclusion in our proxy statement for our 2018 Annual Meeting must send notice of the proposal to our Corporate Secretary at our principal executive office no later than November 24, 2017. If you make such a proposal, you must provide your name, address, the number of shares of common stock you hold of record or beneficially, the date or dates on which such common stock was acquired and documentary support for any claim of beneficial ownership.

In addition, any stockholder who intends to submit nominees for election as directors or a proposal for consideration at our 2018 Annual Meeting, in each case not for inclusion in our proxy materials, must notify our Corporate Secretary. Under our By-Laws, such notice must (1) be received at our executive offices no earlier than November 6, 2017 or later than January 5, 2018, and (2) satisfy specified requirements. A copy of the pertinent By-Law provisions can be found on our Web site at www.mcdermott.com at “INVESTORS — Corporate Governance.”

APPENDIX

Reconciliation of Non-GAAP to GAAP Financial Measure

McDermott reports its financial results in accordance with the U.S. generally accepted accounting principles (“GAAP”). This Proxy Statement includes references to Adjusted Operating Income, a Non-GAAP financial measure as defined under the SEC’s Regulation G. The following table reconciles the Non-GAAP financial measures to Operating Income, the most comparable GAAP financial measures.

	Year Ended Dec 31, 2016
(Dollars In thousands)
GAAP Operating Income	$142,253
Add: Adjustments
Restructuring Charges1	11,263
Impairment Loss2	54,958
Non-Cash Actuarial Loss (Gain) on Benefit Plans3	(5,391)
Total Non-GAAP Adjustments	60,830
Non-GAAP Adjusted Operating Income	$203,083

1	Restructuring charges were primarily associated with personnel reductions, facility closures, consultant fees, lease terminations and asset impairments.
2	Impairment charges: (i) $11.8 million and $10.9 million in the third and fourth quarters, respectively, related to certain marine assets after we determined their carrying values were either not recoverable or exceeded their respective fair values; (ii) $32.8 million in the first quarter related to our Agile vessel following the customer's termination of the vessel charter in May 2016 and given the lack of opportunities for the vessel. The Agile was decommissioned and disposed of in the third quarter.
3	Our Non-GAAP measures exclude 100% of pension actuarial loss (gain) included in our Consolidated Financial Statements, including the $5.4 million gain from year-end mark to market pension adjustments for the year ended December 31, 2016. This adjustment is recorded in selling, general and administrative expenses in the fourth quarter of each year in accordance with our pension accounting policy. Actuarial gains and losses are primarily driven by changes in the actuarial assumptions, discount rates and actual return on pension assets. The $5.4 million 2016 mark to market adjustment was comprised of a $4.5 million gain on our pension plan assets and $0.9 million of lower actuarial pension liabilities. The $4.5 million of mark to market adjustment is the difference between $21.6 million of expected return on pension plan assets recognized during 2016 and a $26.1 million actual gain on plan assets as of December 31, 2016. Our non-GAAP pension adjustment does not include $1.0 million of net pension benefit recognized during 2016 related to expected return on plan assets net of interest costs for our non-contributory defined benefit pension plans.
