DEAR FELLOW U. S. STEEL STOCKHOLDER:

STOCKHOLDER

I want to thankThank you for your investment in U. S. Steel and the trust you have placed in the Board of Directors, as stewards of the Corporation. On behalf of the Board and 30,000 employees of our storied Corporation, I am proudhonored to report that we have made significant progress on our strategic transformation in 2016, and we are beginningbe penning my first update to see results reflecting our efforts.

We began a journey over three years ago to modernizeyou as U. S. Steel intoPresident & CEO and proud to be leading a company that literally helped build the United States and today remains a foundational part of American manufacturing.

Our company experienced some challenges early in the year in terms of our safety, operational and financial performances. However, we pulled together as a team, and by year end we delivered three consecutive quarters of stable, consistent operational and financial performances across our three reporting segments, and our safety performance reflected more agilepositive trends. This focus allowed us to meet or exceed our primary goals for improved EBITDA, cash generation and innovative organization for the 21stcentury global steel industry. While that journey continues andliquidity by year-end. This represents a good start, but we know we still have much work to do to make this kind of stability our new normal, rather than an exception.

After the first quarter, we made meaningful progress in 2016quickly refocused and rallied around four business drivers we identified as key to achieving operational excellence and advancing our performance reflected it with a stock price increase of 300%. Other performance achievements are summarized in the accompanying proxy statement.

ongoing strategic transformation: safety, quality, delivery, and cost. We are structuring our transformation around a process we call the “Carnegie Way,” a disciplined strategic framework named in honor of our co-founder Andrew Carnegie, the visionary leader who foundedknew improving these four pillars would help us:

create value for all U. S. Steel more than 115 years ago. stakeholders, including employees, customers, unions, suppliers, communities in which we operate and all of you, our stockholders;
develop distinct competitive advantages and solutions for our customers;
succeed through business cycles; and
drive predictable, sustainable, profitable growth in the future, including additional re-investment in our business that provides superior returns.

We continuequickly decided to honor Mr. Carnegie’s legacy todayaccelerate plans around the strategic revitalization of assets in our North American Flat-Rolled operations. Guided by executing our strategyCarnegie Way methodology, we developed performance measures around EBITDA return, quality and positioningreliability improvements, and capital spending discipline, and we publicly disclosed those goals because we believe in accountability. We also decided to approach this major, multi-year initiative through a high volume of smaller, less complex and well-managed projects. By year end, we completed 700 projects, exceeded our targets for EBITDA return, quality and reliability, and matched our target for capital spending.

However, investing in our facilities isn't enough if we want to strengthen our ability to compete globally. We acted on several additional fronts tied to safety, quality, delivery, and cost in 2017.

At U. S. Steel, the Corporationhealth and well-being of the people coming to our facilities every day and our efforts to minimize the impact our activities and operations have on our shared environment intersect under the umbrella of "safety." For us, it'salways safety first ... for continued long-term growth. A successful transformationour employees, our environment, and our assets. Last year, we experienced several serious safety incidents across our company. We implemented improvement plans and made strides to reverse our performance, but when it comes to safety, the only acceptable number for incidents and injuries is zero, and we're committed to consistently hitting that goal. We also requires innovation,judiciously and promptly responded to environmental issues. As we did with safety, we continue to prioritizetake steps to improve our focus in this important area. You can read more detail about our safety and environmental efforts in the "Corporate Social Responsibility" section.

Throughout 2017, we further strengthened our balance sheet through a series of new and ongoing actions which led to improved credit metrics and a two-level ratings increase by Moody's, as well as an outlook upgrade – from stable to positive – in our credit ratings by Standard & Poor's, in February 2018. We continued to foster innovation through highly collaborative customer relationships, resulting in the development of new cutting-edge steel solutions such as advanced high-strength steels for automotive customers and proprietary premium tubular connections for the energy industry. We also increased our efforts particularlyaround training, engagement, and other

workforce-related areas. These efforts ensure we get valuable input from our highly creative employees and then provide them with the right resources to take their performance and that of our company to a new level by cultivating collaborative relationshipsfurther delighting our customers. More detail about these and related efforts are located in the "Highlights and Accomplishments" section of the proxy summary.

Overall, our culture is increasingly rooted in continuous improvement with a steadfast commitment to achieving operational excellence in everything we do – from our plant processes to our business practices and everything in between. This made all of last year's progress possible after a tough start, and it will be vital to helping us remain competitive in the global steel industry in the future.

In keeping with our customerscommitment to develop the solutions they need andcontinuous improvement, we are also looking at ways to create more opportunities forimprove our business. The Carnegie Way permeates all aspects of our business from our corporate headquarters in Pittsburgh to our steel mills and operations around the world. We are implementing permanent improvements to enable the Corporation to succeed across the volatile business cycles of the evolving global steel industry.

We undertake our transformational efforts as part of an American steel industry that continues to face considerable macro-economic headwinds and unfair global steel trade practices. The persistent presence of low-cost and potentially inferior imports puts undue pressure on the American manufacturing sector and job market, and represents an unsustainable risk to not only our industry, but our national economy and infrastructure.

In addition to executing on our long-term organizational transformation,workplace culture companywide. At U. S. Steel, continueswe are committed to lead industrygetting better, stronger and more effective every day in everything we do – for our customers, for our communities, for our stockholders, and for one another. We will do better in creating and sustaining a more profitable company with a more supportive workplace culture. I am pleased to have the Board's full support for these efforts.

Also vital to our future is the need to address unfair trade. We were pleased with actions taken last year to combat this long-standing challenge. However, the fundamental cause behind the need for these actions – global overcapacity – remains. Until substantive steps are taken to address this issue and create a level playing field, we will continue to fight for our rights under the law using all available means because we wholeheartedly believe a healthy domestic manufacturing sector needs a healthy domestic steel industry. Regardless of the outcome of current or future trade-related efforts, to tacklewe will remain focused on all the effectsthings we can control that make us a better company, beginning with safety, quality, delivery, and cost.

Our success in all of unfairly traded steel.these areas is predicated on having dedicated and experienced leadership, starting with the Board of Directors. We are leveraging legislative, judicialgrateful for the service of Mario Longhi, who retired in 2017, and regulatory channels, as well asJack Drosdick, Bob Stevens and Glenda McNeal, who all will complete their service on our Board in April. This year we also welcomed Gene Sperling to the

public arena. For example, in 2015 U. S. Steel along with other domestic steel producers filed three petitions with the U.S. DepartmentBoard of CommerceDirectors. Our company is fortunate to be guided by a Board that is invested in and the International Trade Commission. enthusiastic about our future.

In 2016, we saw the successful resolution of those cases, as final determinations imposed duties of significant magnitude on the subject countries. In 2016, we also launched landmark legal action under Section 337 of the Tariff Act to further combat illegal conduct and circumvention of our trade laws. Our progress on this front enables U. S. Steel, and other American steel companies, to compete on a more level playing field with non-U.S. competitors.

Even as difficult conditions may persist,closing, we recognize that we are in a better position today to respond to changing market conditions and we are encouraged byappreciate the improving performance of the Corporation. We continue to invest insupport we've received from our people. With employees at all levels working throughmany stakeholders, including our multi-level Carnegie Way training, we are enablingcustomers, suppliers, unions and all of you, our workforce to complete projects delivering value to our stakeholders and improve our business. We remain steadfast in ourstockholders. Our commitment to becoming a consistently profitable company that conducts business in an ethical andcreating real, sustainable way.

We encourage youour stockholders to vote your shares on the proposals discussed in the accompanying proxy statement. Your involvement isand support are important to the future of our company.

I can confidently say our company is in a much better position today, but we know we still have work to do. We look forward to getting that work done and achieving our country.goals. Now, let's get back to work – safely helping our customers be successful.

Our journey continues.

PROXY SUMMARY

CARNEGIE WAY AND 2016 HIGHLIGHTS AND ACCOMPLISHMENTS (PAGE 21)

The Carnegie Way: Earning the Right to Grow and Driving Sustainable, Profitable Growth

The Carnegie Way, named for our co-founder and famous American industrialist Andrew Carnegie, is a strategic, disciplined approach to transforming the Corporation for the new realities of the marketplace. The Corporation is realizing the benefits of the Carnegie Way today by doing ordinary things extraordinarily well. Since 2013 and the launch of this Board-approved program by our CEO Mario Longhi, the Carnegie Way has driven a dramatic shift in the Corporation that is enabling us to withstand the prolonged downturn in steel prices, and is positioning us for success in a market recovery. With a more intense focus on cash flow and a strong balance sheet, and a revised approach to how we view shipment volume and production, the Corporation is working through a series of transformational initiatives that has enabled us to more effectively add value, get leaner faster, right-size our operations, and improve our performance across core business process capabilities, including: commercial; supply chain; manufacturing; procurement; innovation; and operational and functional support. We are also focused on the development of differentiated, innovative products, processes and approaches to doing business as we create positive solutions for our customers and stakeholders.

2014 was U. S. Steel’s first profitable year since 2008, but macroeconomic factors created profound market challenges for the Corporation that negatively affected revenues, earnings and stock price in 2015 and 2016. Despite these difficult conditions, our focus on what we could control was a significant contributor to 2015 and 2016 results and helped to mitigate many of the negative effects of the challenging economic environment. We believe that without the benefits realized through our Carnegie Way initiatives in 2014, 2015 and 2016, the Corporation would have been much more negatively impacted by market headwinds, including high levels of imports and low global commodity prices.

2016 Highlights and Accomplishments

We began 2016 facing many of the same macroeconomic headwinds as 2015, including historically low steel prices. While these financial uncertainties pointed to another challenging year in 2016, we remained focused on using the Carnegie Way as our guide and executed on strategic priorities critical to the Corporation’s success amid the industry downturn. The unrelenting focus of our executive team and employees on clear actions to improve our balance sheet, enhance operating efficiency, and create fairness and competition in the marketplace were successfully achieved, as evidenced by improvements in our stock price and earnings. While we are proud of these results, our transformation efforts are still underway.

The following are highlights and accomplishments from 2016:

Our stock price increased by more than 300%, reflecting strong execution on our strategy and improved market conditions

Realized $745 million of additional Carnegie Way benefits, building upon the $575 million and $815 million of Carnegie Way benefits realized in 2014 and 2015, respectively, underscoring the success of this transformational process

Ended 2016 with positive operating cash flow of $727 million and adjusted EBITDA of $510 million, despite beginning the year at historically low steel prices and facing the lowest full-year average realized prices since 2004

Strong year-end liquidity of approximately $2.9 billion, including cash on hand of $1.5 billion, which supports our goal of maintaining a healthy balance sheet

Reduced long-term debt by over $100 million in 2016 which contributed to the reduction of net debt by more than 50% since 2013

Successfully completed a $980 million debt offering and a $500 million equity offering, which provide for future financial flexibility

Improved working capital by nearly $600 million, and over $1 billion over the last two years

Continued to aggressively address unfair trade practices through landmark legal action, including leading industry efforts to clarify and enforce existing laws (see, Proxy Summary section “U. S. Steel’s Industry Leading Efforts Against Unfair Trade Practices”)

Out-performed the BLS and AISI industry safety benchmarks in both OSHA Recordable Days and Days Away From Work

PROXY SUMMARY

2017 HIGHLIGHTS AND ACCOMPLISHMENTS (PAGE 23)

Earning the strong link between payRight to Grow and performance embeddedDriving Sustainable Profitable Growth

We are focused on execution of a two-phased stockholder value creation strategy: (1) earn the right to grow, and (2) drive and sustain profitable growth. Earning the right to grow means delivering consistent, reliable EBITDA across the business cycle by achieving operational excellence through a focused effort by our talented workforce to deliver superior results in four business-critical areas: safety, quality, delivery, and cost. Driving and sustaining profitable growth means earning economic profit across the business cycle and above-average returns for long-term stockholders, which is enabled through stable, reliable facilities that produce innovative product and service solutions for discerning steel customers. Underlying both phases is our unwavering commitment to strengthen our balance sheet, with emphasis on cash flow, liquidity, and financial flexibility. We are on a mission to become an industry leader by striving to create a sustainable competitive advantage with a customer-centric focus on: delivering high-quality, on time value-added products; collaborating with customers to develop innovative solutions that address their most challenging needs, including new advanced high-strength steels to meet fuel efficiency and safety requirements for automotive customers and new premium connections for demanding applications of our energy customers in oil and gas drilling; generating economic profit through active participation in relevant markets; and creating and maintaining a competitive cost structure centered around operational flexibility.

Our successful navigation through the industry downturn in 2015 and 2016 better positioned us to benefit from improved industry conditions in 2017, although we continued to face challenges driven by uncertain geopolitical factors. We delivered significant improvement in our Tubular segment, and had continued success from our European operations. We recognized the need to accelerate our plans to revitalize our assets in our North American Flat-Rolled operations through a strategic investment program. The continued focus of our executive team and employees on our long-term strategic goals of improving our balance sheet, enhancing operating efficiency and reliability, and seeking robust enforcement of our trade laws, led to a successful year and helped move us another step closer to achieving sustainable profitability. We made good progress in 2017, and strive for greater achievement in the year ahead.

Asset revitalization and Innovation

In 2017 we announced a $2 billion strategic initiative to revitalize the assets in our North American Flat-Rolled segment. The program is focused on improving company critical assets to deliver 15-20% EBITDA returns over three to four years, through a consistent focus on improving safety, quality, delivery and cost. The Corporation views this program as essential to improving predictability and our ability to compete effectively in the industry. As we revitalize our assets, we expect to increase profitability, productivity, operational consistency, and reduce volatility.

In addition to investing in improvements of our leaders and current assets, we're also focused on the future by investing in our global workforce and the innovation that will create tomorrow's steel solutions today. We've continued our


aggressive efforts around the development of the next generation of advanced high-strength steels (AHSS) for the automotive industry to solve its most pressing challenges. Years of work on AHSS technology culminated with the announcement in September 2017 of the commencement of construction of a new continuous galvanizing line at our PRO-TEC Coating Company joint venture that will feature proprietary technology developed in part by our company. We also launched a new proprietary semi-premium tubular connection – USS-EAGLE SFHTM and sold our first orders of USS-LIBERTY LDTM connections to meet the needs of our customers in the oil and gas industry and to position U. S. Steel as a stronger company by 2020.

PROXY SUMMARY

Human Capital Management and our "Pivot to the People"

Success in achieving our long-term goal of top quartile performance in safety, quality, delivery and cost is fully dependent on the leadership, engagement and commitment of our employees. Over the next several years as we focus on improving our physical assets through significant asset revitalization investments, we must concurrently focus

significant investments in our employees to ensure they have the skills and capabilities necessary to deliver our strategic business objectives. The goal of our human resources strategy is to ensure our human resources initiatives fully support our business objectives in a sustainable fashion throughout the business cycles we face.

Corporate Social Responsibility

Over 100 years ago, we adopted the Gary Principles. The Gary Principles were among the first Codes of Conduct adopted by a publicly traded company and continue to guide us today.

U. S. Steel’s Industry Leading Efforts Against Unfair Trade Practices

The persistent presence of these low-cost and potentially inferior importsgood corporate citizen is not only puts undue pressure on the American manufacturing sector and job market,right thing to do, but also is hazardous to long-term sustainable business practices and represents a very real threatessential to our country’s national securitysuccess. We are more than a global leader in the steel industry; we are your friends, neighbors and infrastructure.community partners. Our employees live and work in the same communities as you. We breathe the same air, drink the same water and share the same hopes and dreams for our families.

Every employee who works in one of our facilities has the right to return home safely at the end of every day. We are working to eliminate all injuries and incidents at all of our locations because it is the right thing to do, but also because it improves productivity, quality, reliability and financial performance. By making safety and health a

We continue to enhance our safety practices for both employees and contractors, as we pursue our zero safety incident goal.

We recognize that the past few years. In lightearth is a shared and finite resource that we all must safeguard for generations to come. It is our commitment to sustainability that drives our operations to adopt management systems and best practices that foster continuous improvement in our processes, preserve vital resources and ensure the future of these circumstances, the industry. We have enhanced our disclosure of actions and results in this area on our website (www.ussteel.com/posts/environmental-stewardship), and plan to release a sustainability report more fully describing our efforts in 2018.

"We must never forget that our rights and interests are and should be subservient to the public welfare, that the rights and interests of the individual must always give way to those of the public." – Gary Principles

U. S. Steel has taken a leadership roleLeads Fight Against Imports for the Domestic Industry and National Security

In 2017, U. S. Steel continued to lead the industry in efforts to address dumped and subsidized imports, as well as imports that threaten national security.

In April 2017, the U.S. Department of Commerce (DOC) initiated an unprecedented effortinvestigation under Section 232 of the Trade Expansion Act of 1962 to reducedetermine the impacteffects of unfairly tradedsteel imports on U.S. national security. U. S. Steel testified at the DOC public hearing and is actively advocating for a meaningful remedy to prevent further harm to the domestic steel industry that is critical to U.S. infrastructure, energy independence, national and economic security.

To address unfair import competition, U. S. Steel focused on maintaining and defending a total of approximately 100 antidumping (AD) and countervailing duty (CVD) orders on flat-rolled and tubular steel products on 26 countries through fierce advocacy before legislative bodies, in the courts,DOC, the U.S. International Trade Commission (ITC), the Administration, Congress, U.S. Courts, the World Trade Organization, and in the public arena.

Also, in 2015,In addition to defending the 2016 AD/CVD orders on hot-rolled, cold-rolled, and corrosion-resistant steel, U. S. Steel collaborated withhas led efforts to maintain AD/CVD orders on tubular steel products.

In December 2017, in response to circumvention petitions filed by U. S. Steel and other domestic steel producers to file a series of three petitions for trade remedies within September 2016, the Department of Commerce and the International Trade Commission. These petitions sought to level the playing field for domestic producers by imposing duties on unfairly traded steel products. In 2016, we saw the successful resolution of those three cases, as final determinations imposed duties of significant magnitude on the subject countries.

We took our efforts further in 2016 by launching a landmark legal action under Section 337 of the Tariff Act of 1930 against ten of the largest Chinese producers and their distributors, alleging conspiracy to fix prices, theft of trade secrets, and circumvention of duties. This action, if successful, would result in a total ban on ChineseDOC preliminarily found that imports of cold-rolled and corrosion-resistant steel products. Additionally, in 2016,made from Chinese substrate are covered by the AD/CVD orders on such imports from China, and imposed significant cash deposit requirements on U.S. imports of cold-rolled steel from Vietnam made from Chinese hot-rolled steel and U.S. imports of corrosion-resistant steel from Vietnam made from Chinese hot- or cold-rolled steel.

In 2018, U. S. Steel collaborated with other domestic steel producers to petition the Department of Commerce to investigate Chinese producers’ circumvention of duties by diverting steel products to Vietnam en route to the United States. We continue to vigorously pursue every legal avenue available to ensure that our trade laws will be enforced.

We also have: continued our dialogue with the relevant federal agencies to change certain regulatory practices and procedures; commenced substantive work with regional trade partners and organizations; and outlined a robust engagement with the White House to tackle global overcapacity through bilateral and unilateral negotiations. At this critical time for the industry, and for our country, U. S. Steel has been, and will continue to be, a leader on these issuesaggressively and strategically use U.S. trade laws to promote consistent and fair enforcement of our laws.address unfair import competition.

Proposal 1: Election of Directors

PROPOSAL 1: ELECTION OF DIRECTORS

In 2014, U. S. Steel’s Board of Directors and stockholders approvedAt the elimination of the classified board structure. The process to declassify the Board was phased out over a three-year period and will be complete as of the 20172018 Annual Meeting, of Stockholders. At the 2017 Annual Meeting, all twelveten directors are up for election. Of the current directors nominated for election three were previously Class I directors and nine were elected last year for a one-year term. Each nominee will be elected to serve until our next annual meeting of stockholders. All of the nominees are presently members of the Board of Directors. The Board is recommending that all twelveten nominees be elected.

John G. Drosdick will retire from the Board as of the expiration of his term at the 2018 Annual Meeting in accordance with our Director Retirement Policy, described on page 13. Additionally Mr. Stevens and Ms. McNeal decided not to stand for re-election.

Except in the case of contested elections, each director nominee is elected if a majority of the votes are cast for that director’sdirector's election. The term “a"a majority of the votes cast”cast" means that the number of votes cast “for”"for" a director’sdirector's election exceeds the number of votes cast “against”"against" the director’sdirector's election, with abstentions and broker non-votes not counted as votes cast either “for”"for" or “against”"against" the director’sdirector's election. A “contested election”"contested election" is one in which the number of nominees exceeds the number of directors to be elected at the meeting.

If a nominee who is currently serving as a director is not re-elected, Delaware law provides that the director would continue to serve on the Board until the director’sdirector's successor is duly elected and qualified or until the director’sdirector's earlier resignation or removal. Under our by-laws, in order for any incumbent director to become a nominee for election by the stockholders as a director, that director must tender an irrevocable offer to resign from the Board of Directors, contingent upon acceptance of such offer of resignation by the Board of Directors, if the

director fails to receive a majority of the votes cast in an election that is not a contested election. If an incumbent director fails to receive a majority of the votes cast in an election that is not a

contested election, the Corporate Governance & Public Policy Committee, or such other independent committee designated by the Board of Directors, must make a recommendation to the Board of Directors as to whether to accept or reject the offer of resignation of the incumbent director, or to take other action.

The Board of Directors must act on the offer of resignation, taking into account the committee’scommittee's recommendation, within 90 days following certification of the election results. Each of the Corporate Governance & Public Policy Committee, in making its recommendation, and the Board of Directors, in making its decision, may consider such factors and other information as it may consider appropriate and relevant to the circumstances.

A brief statement about the background and qualifications of each nominee is provided on the following pages. No director has a familial relationship to any other director, nominee for director or executive officer. The independence of Board members and other information related to the Board of Directors is described under the heading, “Corporate"Corporate Governance – Independence”Independence" in this proxy statement.

Mr. Sperling is the only nominee who has not been previously elected to the Board by our stockholders. His nomination was recommended by the Chairman of the Board after consultation with certain stakeholders.

If any nominee for whom you have voted becomes unable to serve, your proxy may be voted for another person designated by the Board.

The Board recommends a vote “FOR” the election of each nominee.

GRAPHICThe Board recommends a vote "FOR" the election of each nominee.


Selection of Director Nominees

The Corporate Governance & Public Policy Committee is responsible for identifying nominees for election to the Board. The Corporate Governance & Public Policy Committee may consider nominees suggested by several sources, including outside search firms, incumbent Board members and stockholders.

As provided in its charter, the Corporate Governance & Public Policy Committee seeks candidates with experience and abilities relevant to serving as a director of the Corporation and who will represent the best interests of stockholders as a whole, and not any specific interest group or constituency.

The Corporate Governance & Public Policy Committee, with input from the Chairman of the Board and other directors, evaluates the qualifications of each director candidate in accordance with the criteria described in the director qualification standards section of our Corporate Governance Principles. In evaluating the qualifications of director

nominees, the Corporate Governance & Public Policy Committee considers factors including, but not limited to, the following:

Independence.Directors should neither have, nor appear to have, a conflict of interest that would impair the director’sdirector's ability to represent the interests of all the Corporation’sCorporation's stakeholders and to fulfill the responsibilities of a director.

Commitment.Directors should be able to contribute the time necessary to be actively involved in the Board and its decision-makingdecision making and should be able and willing to prepare for and attend Board and committee meetings.

Diversity.Though the Board does not have a formal policy regarding the consideration of diversity in identifying nominees for director, directors should be selected so that the Board represents diverse experience at various policy making and executive levels in business, government, education and in industries that are relevant to the Corporation’sCorporation's business operations. The Board considers the

term “diversity”"diversity" to include differences of viewpoint, professional experience, education, skill and other individual qualities and attributes that contribute to board heterogeneity.


   United States Steel Corporation | 2017 Proxy Statement   |   1

Proposal 1: Election of Directors

Experience.Directors should be or have been in leadership positions in their field of endeavor and have a record of excellence in that field.

Integrity.Directors should have a reputation of integrity and be of the highest ethical character.

Judgment.Directors should have the ability to exercise sound business judgment on a large number of matters.

Knowledge.Directors should have a firm understanding of business strategy, corporate governance and board operations and other relevant business matters.

Skills.Directors should be selected so that the Board has an appropriate mix of skills in critical core areas, including, but not limited to: accounting, compensation, finance,

government relations, legal, management, risk oversight and strategic planning.

These director qualification standards are evaluated by the Corporate Governance & Public Policy Committee each time a new candidate is considered for Board membership. The Corporate Governance & Public Policy Committee and the Board may take into account such other factors they consider to be relevant to the success of a publicly traded company operating in the steel industry. As part of the annual nomination process, the Corporate Governance & Public Policy Committee reviews the qualifications of each director nominee, including currently serving Board members, and reports its findings to the Board. On February 27, 2017,2018, the Corporate Governance & Public Policy Committee determined that each Board member satisfied the director qualification standards and advised the Board that each of the director nominees listed under “Proposal"Proposal 1: Election of Directors”Directors" was qualified to serve on the Board.

BOARD LEADERSHIP STRUCTURE

The Board regularly considers the appropriate leadership structure for the Corporation. It has concluded that the Corporation and its stockholders are best served by the Board retaining discretion to determine whether the same individual should serve as both Chief Executive Officer and Chairman of the Board, or whether the Chairman of the Board should be an independent director. The Board believes that it is important to retain the flexibility to make this determination at any given point in time based on what it believes will provide the best leadership structure for the Corporation, taking into account the needs of the Corporation at that time. Due to the high level of transition in the Corporation’sCorporation's executive leadership and the dynamic business environment in 2013 and 2014, the Board chose to implement a non-executive, independent Chairman role in January 2014 to allow the Chief Executive Officer to strategically focus on the associated business challenges. David S. Sutherland currently serves as the independent Chairman of the Board.

If the Chairman of the Board is not independent, the independent directors annually elect from among themselves a

a Lead Director. If the Chairman of the Board is independent, the Chairman’sChairman's duties also include the duties of the Lead Director. The duties of the Lead Director are as follows:

chair executive sessions of the non-employee directors;

serve as a liaison between the Chief Executive Officer and the independent directors;

approve Board meeting agendas and, in consultation with the Chief Executive Officer and the independent directors, approve Board meeting schedules to ensure there is sufficient time for discussion of all agenda items;

approve the type of information to be provided to directors for Board meetings;

be available for consultation and direct communication with the Corporation's stockholders;

call meetings of the independent directors when necessary and appropriate; and

BOARD’SBOARD'S ROLE IN RISK OVERSIGHT

Pursuant to its charter, the Audit Committee is responsible for reviewing and discussing the Corporation’sCorporation's policies with respect to the assessment of risks and risk management, including the following:

the guidelines and policies that govern the process by which the assessment and management of the Corporation’s exposure to risk are handled by senior management; and
the Corporation’s major risk exposures and the steps management has taken to monitor and control such exposures.

the guidelines and policies that govern the process by which the assessment and management of the Corporation's exposure to risk are handled by senior management; and

the Corporation's major risk exposures and the steps management has taken to monitor and control such exposures.

The Corporation’sCorporation's Internal Audit group provides regular reports to the Audit Committee on the results of various internal audit projects and provides recommendations for the enhancement of operational functions in order to reduce certain risks. Although the Audit Committee has primary responsibility for overseeing risk management, each of our other Board committees also considers the risks within their specific areas of responsibility. For example, the charter of the Compensation & Organization Committee gives it responsibility for assessing whether the Corporation’sCorporation's compensation and organization policies and practices for executives and non-executives are reasonably likely to create a risk that could have a material adverse effect on the Corporation. Pursuant to its charter, the Corporate Governance &

Public Policy Committee considers the risks

associated with legislative, regulatory and public policy issues affecting the Corporation’sCorporation's businesses and operations. Each committee regularly reports to the full Board on theirits respective activities, including, when appropriate, those activities related to risk assessment and risk management oversight.

The Board, as a whole, also considers risk assessment and risk management. For example, the Board annually reviews the Corporation’sCorporation's strategic plan which includes a review of risks related to: safety, environmental, operating and competitive matters; political and regulatory issues; employee and labor issues; and financial results and projections. Management regularly provides updates to the Board related to legal and compliance risks and cyber-security matters.

The Chief Risk Officer is responsible for the Corporation’sCorporation's financial and business risk management, including the assessment, analysis and monitoring of business risk and opportunities and the identification of strategies for managing risk. The Chief Risk Officer provides regular reports to the Audit Committee and Board of Directors on these matters.

The Corporation believes that its leadership structure, as described above, supports the Board’sBoard's role in risk oversight.


BOARD OVERSIGHT OF STRATEGY

A primary responsibility of our Board is oversight of our business strategy. At each regular Board meeting throughout the year, our Board reviews our strategy, operating plans, and overall financial performance, and progress on each, and provides significant guidance and feedback. In addition, at least one multi-day meeting each year is dedicated to focus on our long-term strategic planning. The Board also devotes significant time to reviewing our capital allocation strategy. Annually, our Board reviews and approves our capital authorization and spending budgets, which are designed to strategically deploy capital intended to facilitate investments

required to achieve operational excellence, drive business growth and generate strong returns. Our capital allocation is aligned to support our strategic priorities, with a focus on preserving a strong balance sheet, a strong liquidity profile and financial flexibility. To oversee management's performance in executing our strategy, the Board receives regular updates and actively engages in dialogue with our executive management team. Members of our Board also periodically visit our facilities to monitor the execution of our strategy in our business units, and to assess areas for improvement or potential risk.

BOARD OVERSIGHT OF SUCCESSION PLANNING

Our Board and management consider succession planning and peopleprofessional development to be an integral part of the Corporation’sCorporation's long-term strategy. The Compensation & Organization Committee is responsible for monitoring our management succession and development plans and receives regular updates on employee engagement, diversity and retention matters, which are reported to the full Board. At least twice annually, our full Board reviews senior management

management succession and development plans with our CEO. Our CEO then presents to the independent directors his evaluations and recommendation of future candidates for the CEO position and other senior leadership roles and potential succession timing for those positions, including under emergency circumstances. The Board also reviews and discusses development plans for individuals identified as high-potential candidates for senior leadership positions.


BOARD REFRESHMENT

Our Board maintains a robust process in which the members focus on identifying, considering and evaluating potential board candidates. Our Corporate Governance & Public Policy Committee leads this process by considering prospective candidates at its meetings. In identifying appropriate candidates through a thoughtful evaluation,

supported by its outside consultants, the committee is focused on aligning the skills, experience and characteristics of our Board with the strategic development of the company. Among other things, the members aim to strike a balance between the knowledge that comes from longer-term service on the Board with the fresh insights that can come from

BOARD SELF-ASSESSMENTS

Each year, the Board conducts annual self-evaluations to determine whether it and its committees are functioning effectively and whether its governing documents continue to remain appropriate. Our Board’sBoard's self-evaluation is facilitated by a wide range of questions related to topics including operations, composition of the board, responsibilities, governing documents and resources. The Board evaluation also includes an assessment of whether the Board (i) has the appropriate mix of skills, experience and other

characteristics, including those

described earlier, and (ii) is made up of a sufficiently diverse group of people. The process is designed and overseen by the Corporate Governance & Public Policy Committee, and the results of the evaluations are discussed by the full Board.

Each standing committee, other than the Executive Committee, annually reviews its own performance and reports the results and any recommendations to the Board.


INDEPENDENCE

The following non-employee directors are independent within the definitions of independence of both the New York Stock Exchange (“NYSE”)(NYSE) listing standards and the U.S. Securities and Exchange Commission (“SEC”)(SEC) standards for Audit Committee members: Patricia Diaz Dennis, Dan O. Dinges, John G. Drosdick, John J. Engel, Murry S. Gerber, Stephen J. Girsky, Paul A. Mascarenas, Glenda G. McNeal, Eugene B. Sperling, Robert J. Stevens, David S. Sutherland and Patricia A. Tracey. The Corporation has incorporated the NYSE and SEC independence standards into its own categorical standards for independence. The Board has affirmatively determined that none of the directors or nominees for director, other than Mr. Longhi,Burritt, has a material relationship with the Corporation. The Board made such determination based on all relevant facts and circumstances.

In making its determination of director independence, the Board of Directors considered the fact that U. S. Steel purchased certain goods and services from WESCO International, Inc. (WESCO) in 2016.2017. Mr. Engel is the Chairman, President and Chief Executive Officer of WESCO. The Board determined that Mr. Engel did not have a direct or indirect material interest in these transactions and that the transactions were undertaken in the ordinary course of business. In addition, the value of materials purchased by U. S. Steel in 20162017 was less than 2% of WESCO’sWESCO's annual gross revenues. As a result, the Board concluded that these transactions would not affect Mr. Engel’sEngel's independence.

Additionally, the Board considered the fact that U. S. Steel indirectly sold products to Cabot Oil & Gas Corporation (“Cabot”("Cabot") in 2016.2017. Mr. Dinges is the Chairman, President and Chief Executive Officer of Cabot. The Board determined that Mr. Dinges did not have a direct or indirect material interest in these transactions and that the transactions were undertaken in the ordinary course of business, and that the products sold by U. S. Steel were less than 2% of Cabot’sCabot's annual gross revenues. Accordingly, the Board concluded that these transactions would not affect Mr. Dinges’Dinges' independence.

The Board affirmatively determined that each member of the Audit Committee: (i) did not accept directly or indirectly any consulting, advisory, or other compensatory fee from the Corporation or any of its subsidiaries, (ii) was not an affiliated person of the Corporation or any of its subsidiaries, and therefore (iii) satisfied the NYSE’sNYSE's enhanced independence standards for audit committee members.

The Board also determined that: (i) no member of the Compensation & Organization Committee has a relationship to the Corporation which is material to that director’sdirector's ability to be independent from management in connection with the duties of a compensation committee member, and (ii) each member of the Compensation & Organization Committee therefore satisfies the independence requirements of NYSE listing standards.

The charter requires the Audit Committee to perform an annual self-evaluation, review its charter each year and meet at least five times each year. During the fiscal year ended December 31, 2016, the Audit Committee held five meetings.

The Audit Committee annually requests PwCPriceWaterhouseCoopers LLP (PwC) to prepare a self-assessment utilizing the Center for Audit Quality, External Auditor Assessment Tool. This best practice assists the Audit Committee in its oversight role and annual evaluation of PwC to assess the quality of the audit and to recommend the retention of PwC. Based on this assessment, we believe the quality of PwC’sPwC's services, communication and interaction with the Audit Committee is of a high standard.

The charter also requires the Audit Committee to be comprised of at least three directors, each of whom is independent and financially literate, and at least one of whom must have accounting or related financial management expertise. Under the charter, no director who serves on the audit committees of more than two other public companies may serve on the Audit Committee, unless the Board determines that such simultaneous service will not impair the ability of such director to effectively serve on the Audit Committee. No member of the Audit Committee serves on the audit committees of more than two other publicly traded companies. The Board has determined that John J. Engel, the Committee’sCommittee's chairman, Dan O. Dinges, Murry S. Gerber and Stephen J. Girsky and David S. Sutherland meet the SEC’sSEC's definition of audit committee financial expert.

DIRECTOR COMPENSATION

DIRECTOR COMPENSATION

Our Corporate Governance Principles provide that each non-employee director shall be paid compensation as the Board may determine from time to time. Directors who are employees of U. S. Steel receive no compensation for their service on the Board.

The objective of U. S. Steel’sSteel's director compensation programs is to enable the Corporation to attract and retain as directors individuals of substantial accomplishment with demonstrated leadership capabilities. In order to align the interests of directors with the interests of stockholders, our non-employee directors participate in the Deferred Compensation Program for Non-Employee Directors and the Non-Employee Director Stock Program, each of which is described below.

For 2016, Non-employee2017, non-employee directors were paid an annual retainer fee of $200,000.$240,000. Committee Chairs and the Chairman of the Board were paid an additional annual fee of $20,000 and $50,000, respectively. No meeting fees or committee membership fees are paid.

Under our Deferred Compensation Program for Non-Employee Directors, each non-employee director is required to defer at least 50% of his or her retainer in the form of Common Stock Units and may elect to defer up to 100%. A Common Stock Unit is what is sometimes referred to as “phantom stock”"phantom stock" because initially no stock is actually issued. Instead, we keep a book entry account for each director that shows how many Common Stock Units he or she has. When a director leaves the Board, he or she receives actual shares of common stock corresponding to the number of Common Stock Units in his or her account. The ongoing value of each Common Stock Unit equals the market price of the common stock. When dividends are paid on the common stock, we credit each account with equivalent amounts in additional Common Stock Units. If U. S. Steel were to undergo a change in control resulting in the removal of

a non-employee director from the Board, that director would receive a cash payment equal to the value of his or her deferred stock account.

Under our Non-Employee Director Stock Program, upon joining our Board, each non-employee director is eligible to receive a grant of up to 1,000 shares of common stock. In order to qualify, each director must first have purchased an equivalent number of shares in the open market during the 60 days following the first date of his or her service on the Board.

The Corporate Governance & Public Policy Committee reviews and sets director compensation on a semi-annualan annual basis. In November 2016, Thethe committee reviewed information and recommendations from Pay Governance, an independent compensation consultant, for the same comparator group of 24 companies the Compensation & Organization Committee uses for determining compensation for our executives, as well as for a larger general comparator group of 151 companies in a similar revenue range as the Corporation. After reviewing the information presented by Pay Governance, as well as other public information on the topic, the committee determined that the plan design was consistent with market trends, but that the amount of our directors’directors' annual base retainer, which was set in 2011, was below the 25th percentile and significantly below the 50thpercentile of both comparator groups. The Corporate Governance & Public Policy Committee determined torecommended, and the Board approved, an increase in the annual director compensation retainer to $240,000 beginning in 2017, in order to align the compensation level with the median of both comparator groups. No increase was made to the additional amounts paid to the board chair or to committee chairs.

In 2017, the Corporate Governance & Public Policy Committee reviewed director compensation information of the peer group and a general comparator group, and made no changes to the director compensation fees for 2018. Mr. Sutherland's annual retainer was temporarily increased by $150,000, effective March 1, 2018, in connection with his assumption of additional duties.

STOCK OWNERSHIP OF DIRECTORS AND EXECUTIVE OFFICERS

STOCK OWNERSHIP OF DIRECTORS AND EXECUTIVE OFFICERS

The Board has adopted stock ownership and holding requirements for executive officers. These requirements are described under the caption “A Culture of Ownership”"Stock Ownership and Holding Guidelines" in the Compensation Discussion and Analysis section of this proxy statement.

Non-employee directors are required to hold equity interests in the Corporation in the form of stock-based deferred compensation. This requirement is a part of our Corporate Governance Principles. Each non-employee director is required to defer at least 50% of his or her annual retainer as stock-based compensation under the Deferred Compensation Program for Non-Employee Directors. Amounts deferred are credited to the director’sdirector's deferred stock account in the form of Common Stock Units. No amounts are paid to the director from the deferred stock account until the director leaves the Board, at which time he or she receives actual shares of common stock

corresponding to the number of Common Stock Units in his

or her account. The Board and management believe that such deferral, by continually building each director’sdirector's equity interest in the Corporation, provides a meaningful continued interest in the Corporation that is tied to the stockholders’stockholders' interest because the stock issued upon a director’sdirector's departure from the Board reflects all changes in the market value of U. S. Steel common stock from the date of deferral. Each non-employee director is in compliance with the requirement described in this paragraph.

The following table sets forth the number of shares of U. S. Steel common stock beneficially owned as of February 27, 201726, 2018* by each director and director nominee, by each executive officer named in the Summary Compensation Table and by all directors and executive officers as a group. No director or executive officer beneficially owned, as of the applicable date, any equity securities of U. S. Steel other than those shown.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Under Section 16(a) of the Securities Exchange Act of 1934, our directors and executive officers and persons holding more than ten percent10% of any class of our equity securities, are required to file with the SEC initial reports of their ownership of our common stock and reports of changes in such ownership. To our

knowledge, based on information furnished to us during 2017, there were no late filings by any U. S. Steel directors, executive officers or other persons subject to Section 16(a) of the Securities Exchange Act of

1934 required to be disclosed in this proxy statement. In December 2017, an amendment to the applicable Form 3 was filed for each of Christine Breves and Scott Buckiso disclosing ownership of phantom shares through the Corporation's Supplemental Thrift Program. These shares were inadvertently omitted from the initial Forms 3 that were timely filed upon their designation as an "executive officer" under the federal securities laws.

United States Steel Corporation | 2017 Proxy Statement   |   19Certain Legal Matters

CERTAIN LEGAL MATTERS

On October 2, 2017, an Amended Shareholder Class Action Complaint was filed in Federal Court in the Western District of Pennsylvania consolidating previously-filed actions. Separately, four related shareholder derivative lawsuits were filed in State and Federal courts in Pittsburgh. The underlying consolidated class action lawsuit alleges that the Corporation, certain current and former officers, an upper level manager of the Corporation and the financial underwriters who participated in the August 2016 secondary public offering, violated federal securities laws in making false statements and/or failing to discover and disclose material information regarding the financial condition of the Corporation. The lawsuit claims that this conduct caused a

prospective class of plaintiffs to sustain damages during the period of January 27, 2016 and April 25, 2017 as a result of the prospective class purchasing the Corporation's common stock at artificially inflated prices and/or suffering losses when the price of the common stock dropped. The derivative lawsuits generally make the same allegations against the same officers and also allege that certain members of the Board of Directors failed to exercise appropriate control and oversight over the Corporation and were unjustly compensated. They seek to recover losses that were allegedly sustained. The Corporation is vigorously defending these matters.

Earning the Right to Grow and CompetitiveDriving Sustainable Profitable Growth





Over the past few years, U. S. Steel, like the American steel industry in general, has faced difficult market conditions as a result of macroeconomic challenges, including significant reductions in the market price of steel, global overcapacity and record levels of unfairly traded imports, slow growth globally, a strong U.S. dollar, and markedly low energy prices. In the face of these challenging conditions, we initiated a process that provides the framework for a multi-year transformation to return our company to top quartile performance and sustainable profitability through the business cycle.

We are on a mission to become an industry leader by striving to create a sustainable competitive advantage with a customer-centric focus on: delivering high-quality, value-added products on time every time; collaborating with our customers to develop innovative solutions that address their most challenging needs, including new advanced high-strength steels to meet fuel efficiency and safety requirements for automotive customers and new premium connections that provide strong, durable connections between pipes used by energy customers in oil and gas drilling; generating



economic profit through active participation in relevant markets; and creating and maintaining a competitive cost structure centered around operational flexibility. As part of this process, we have aligned our company with commercial entities to drive customer intimacy in order to foster innovation and be more responsive to their needs. We focus on our strengths, how we can create the most value for our stockholders and best serve our customers, with committed and engaged executives and employees.

We have launched a series of initiatives that we believe will enable us to achieve true operational excellence by improving our performance across our core business processes, including commercial, supply chain, manufacturing, procurement, innovation, and operational and functional support. Our highly talented, capable and collaborative employees are the driving force behind many of these continuous improvement projects, and their efforts are creating a culture where accountability and high performance are valued and celebrated.

The Carnegie Way: Earningthem remains as strong as the Right to Grow and Driving Sustainable Profitable Growth

Over the past few years, U. S. Steel, like the American steel industry in general, has faced difficult market conditions as a result of macroeconomic challenges, including significant reductions in the market price of steel, global overcapacity and record levels of unfairly traded imports, slow growth globally, a strong U.S. dollar, and markedly low energy prices. In the face of these challenging conditions, in 2013products we initiated a transformational process called the Carnegie Way. This process provides the framework for a multi-year journey to return our company to iconic status and sustainable profitability.

The objective of the Carnegie Way is to focus our executives and employees throughout the organization on the factors we can control. Accomplishing this objective includes creating a lower and more flexible cost structure that will produce stronger and more consistent results across industry cycles to mitigate the financial impact of the volatility in our industry. We are focused on the development of differentiated, innovative products, processes and approaches to doing business – through a culture of collaboration, accountability and demonstrating results. As part of this process, we have reorganized our company into commercial entities to facilitate close collaboration with our customers in order to foster innovation and to be more responsive to their needs. The

Carnegie Way is our culture and the way we run the business. We focus on our strengths, how we can create the most value for our stockholders and best serve our customers, with committed and engaged executives and employees.

make every day.

Our success in this transformation is predicated on having the right leaders to guide the Corporation and successfully execute on our strategy, so it is critical to attract and retain the highest level of executive talent. We believe we have the right leadership team, which includes highly experienced executives from both inside and outside of the steel industry,

to continue to lead the Corporation through the operational, market and regulatory hurdles facing our business.

Our executive compensation program has been structured to closely align with the objectives of the Carnegie Way transformation: attract, reward and retain talented executives; focus our executives on the goals that are within their control and support our strategy; and clearly and closely align with company performance, and the long-term interests of stockholders, using measurable financial metrics. We believe both the structure of our compensation programs and the pay outcomes for executives demonstrate our strong commitment to linking compensation to company performance and strategy.


Executive Leadership Transition

In May 2017, Mario Longhi announced his retirement from the Corporation after serving as the Corporation's Chief Executive Officer since 2013. David B. Burritt, who has been with the Corporation since 2013 and served most recently as President and Chief Operating Officer, was promoted to President & Chief Executive Officer and appointed as a member of the Board of Directors. The promotion of Mr. Burritt reinforces the Board's confidence in the Corporation's leadership team and commitment to the long-term transformational strategy initiated by Mr. Longhi. The Corporation's 2017 highlights and accomplishments, described on the next page, are a testament to the

successful transition of executive leadership, and Mr. Burritt's intense focus on continuous improvement in the areas of safety, quality, delivery and cost.

   United States Steel Corporation | 2017 Proxy Statement   |   21

In connection with his retirement, Mr. Longhi entered into a separation agreement with the Corporation, which provided for, among other things, pro rata vesting of certain 2015 and 2016 long-term incentive awards, a pro rata portion of any award under the annual incentive compensation plan, and certain retirement benefits. Under the agreement, Mr. Longhi forfeited all of his 2017 long-term incentive awards. This agreement is described in more detail on page 36.

Asset revitalization and Innovation

In 2017 we are taking actionable steps nowannounced a $2 billion strategic initiative to respondrevitalize the assets in our North American Flat-Rolled segment. The program is focused on improving company critical assets to deliver 15-20% EBITDA returns over three to four years, through a consistent focus on improving safety, quality, delivery and return thecost. The Corporation views this program as essential to stable profitability. We are also planning long-term initiatives that are designedimproving predictability and our ability to benefit our business and performance regardless of external market factors.

Near-Term Steps to Return to Profitability. Our management team took several critical actions in 2016, including: idling facilities; right-sizing the organization; and exiting parts of the business where it is not possible to earn an economic profit. These were tough decisions for the executive team and, despite the challenging economic circumstances, U. S. Steel ended 2016 as a more streamlined organization focused on generating economic profit across all business cycles. We continue to focus on improving our product mix with more value-added solutions that differentiate U. S. Steel from our competitors. Our management team is confident that, as market conditions continue to improve, we will realize further benefits from this strategy.
Longer-Term Steps to Improve Our Position. We continue to take steps to improve our position for the long-term. In May, we completed a $980 million offering of senior secured notes, which allowed us to repay near-term debt. In August we completed a $500 million equity offering.

Compensation Discussion and Analysis – Executive Summary

 

Maintaining Pay-for-Performance Approach through Industry Cycles

The Committee believes it is critical to align our compensation program with the goals of the Carnegie Way as we carry out our strategic turnaround initiatives in a challenging operating and unpredictable economic environment. Therefore, our compensation structure balances the following:

a strong pay-for-performance approach that links financial performance to the incentive opportunities realized by our executives;
measurable performance metrics in our incentive plans that support our strategic and financial goals;
alignment of management interests with the long-term interests of our stockholders; and
a strong pay-for-performance approach that links financial performance to the incentive opportunities realized by our executives;

measurable performance metrics in our incentive plans that support our strategic and financial goals;

alignment of management interests with the long-term interests of our stockholders; and

our need to retain executives best qualified to guide the Corporation through its transformation.

The elements of compensation provided to our executives include: base salary, short-term annual incentive compensation, long-term incentive compensation, retirement benefits, and other compensation. The distribution of compensation among the various compensation elements is based on the Committee’sCommittee's belief that to link pay to performance, most of an executive’sexecutive's compensation should be paid in the form of performance-based variable compensation with a greater emphasis on variable components for the most senior executives who have greater responsibility for the performance of the business.


Variable, at-risk compensation accounted for 73%74% of our CEO’sCEO's target compensation in 2016.2017. Based on this strong pay-for-performance alignment, realizable compensation for our CEO over the last three years is 37%42% above the target value granted during the period. Notable aspects of

Compensation Decisions and Outcomes Demonstrate Alignment with Performance

Compensation Decisions for 2016

In early 2016, theThe Committee approved the following items based on several factors, including: the Corporation’s 2015Corporation's 2016 performance; outlook for 20162017 performance; continued development and execution of the Carnegie Way transformationlong-term strategy; assumption of additional duties in connection with executive leadership changes and responsibilities of each of our NEOs; among other criteria.

Salaries: No change was made to the CEO’s base salary for 2016. While the Committee has generally set base salaries above median to support recruitment and retention during the period of transition, no increase was made for the CEO or any other named executive officers for 2016, other than Mr. Bruno, in recognition of the Corporation’s lower financial performance in 2015 and continued market challenges. Mr. Bruno received a base pay increase in 2016 to better align his base salary with other NEOs in the Corporation and comparable roles across our peer group.
Annual Incentive: Target incentive percentages for NEOs did not increase for 2016. Our NEOs earned cash incentives under the AICP based on rigorous goals set in early 2016 that were exceeded through superior performance. These incentives were paid in early 2017.
Long-Term Incentive: The grant date value of the 2016 long-term grant for each NEO decreased from 2015. In order to avoid a windfall of shares to any executive during a period of depressed stock price, the Committee adjusted the target LTIP award using an assumed share price greater than the grant date fair market value to determine the number of shares to be granted. The grant date value of Mr. Longhi’s LTIP award decreased from $7,535,000 in 2015 to $6,887,837 in 2016.
CEO Compensation Decisions for 2017

Salary:  In connection with his promotion to CEO, the Committee set the base salary of Mr. Burritt below the median for the CEO position, which is lower than that of the former CEO. Following the leadership change, the Committee determined to set a greater percentage of the CEO's target compensation as incentive-based compensation.

Annual Incentive:  Mr. Burritt's target incentive percentage under our AICP was increased to 140% of base salary in connection with his promotion to CEO (down from the 150% target of our prior CEO). Mr. Burritt did not receive an annual cash incentive award for 2017.

Long-Term Incentive:  The target value of Mr. Burritt's LTIP award increased from $2,750,000 to $6,100,000 in connection with his promotion to CEO (below the 2016 target of $8,750,000 for our prior CEO).

Total Compensation:  Mr. Longhi’sBurritt's target pay decreased from 2015increased in connection with his elevation to 2016. However, because payouts were made under the AICProle of President & CEO, though it remains lower than the total target compensation of our former CEO by $4 million. The amounts shown for 2016 performance, his actual total pay for 2016, as disclosedMr. Burritt in the Summary Compensation Table increased from 2015 whenreflect his service for a portion of the NEOs did not receive cash incentive payouts under the AICP.year as Executive Vice President & Chief Financial Officer and Chief Operating Officer.

The Committee believes pay decisions for 20162017 demonstrate the significant link between executive compensation and company performance, and accountability of our executives to deliver value to our stockholders.

Other Compensation Decisions

Generally base salaries and target AICP and LTIP grants did not increase for our NEOs in 2017. The Committee did approve an increase in base salary, AICP target and LTIP target for Mr. Buckiso to better align his compensation with other NEOs and comparable roles across our organization and the peer group. Additionally, in February 2017, Mr. Soni was promoted to Vice President – Finance and received a corresponding increase in all compensation elements, consistent with other executives at the Vice President level.

Compensation Outcomes: Payouts Reflect Corporate Performance

The Committee considers a mix of cash and equity awards over both the short-term and long-term as a critical balance in reinforcing U. S. Steel’sSteel's commitment to performance alignment. This strong pay-for-performance alignment is clearly reflected in amounts actually earned by our NEOs based on the achievement of metrics established by the Committee for the short-term and long-term incentive plans.

The average annual incentive payout over the last three years for our named executive officers is 137%94% of target, and no payouts were made in 2015 based on actualthe Corporation's financial performance. Below target performance award payouts have been made under our long-term incentive plan during this same time period, with no payouts for the 2012-20142014 performance awards, 2014-2016 or 2015-2017 ROCE performance awards and nobelow target payout for the 2014-2016 ROCE2015-2017 TSR performance awards.

Changes to 2017 Compensation Program

The Committee approved the following changes to our compensation program in 2016 to more closely align it with our current strategy, position and performance results. TheseNo changes were informed,made to the design of the AICP or the LTIP for 2017. The following modification was made in part, by feedbackrecognition of the experienced executive hires that have been made over recent years, in order to ensure they receive full and fair benefits under the Corporation's retirement programs.

Vesting Upon Retirement –For LTIP awards granted in 2017 and later, the Committee received from stockholders duringrevised the Corporation’s regular engagementvesting requirements, so that awards shall be prorated upon

retirement: (i) after 30 years of service and (ii) at age 55 with investors.10 years of service; and fully vested upon retirement, provided the executive remains employed with the Corporation for at least six months following the grant date: (i) at age 60 with 5 years of service, and (ii) at age 65. The revision is not applicable to participants in the Supplemental Pension Program, which includes Mr. Matthews.

Adopted New Performance Peer Group In February 2016, the Committee created a second, more industry focused peer group consisting of 12 domestic steelCompensation Discussion and steel-related companies against which we measure TSR for purposes of the relative TSR performance awards (described in more detail later under “Peer Group” discussion).
Adopted a Negative TSR CapAnalysis –In February 2016, the Committee added a cap to the relative TSR performance awards to address the potential of negative returns over a performance period (described in more detail later under “TSR Performance Awards” discussion). Executive Summary
Replaced EBIT with EBITDA for AICP Metric In February 2016, the Committee replaced EBIT with EBITDA as a performance metric under our Annual Incentive Compensation Plan to align external and internal communication regarding financial performance.
Equally Weighted EBITDA and Cash Flow For 2016 AICP performance, EBITDA and Cash Flow are equally weighted, in order to place a greater emphasis on the Corporation’s strategic focus on cash flow. In prior years, EBIT accounted for 60% of the award and Cash Flow for 40%.
Alignment of Safety Metric with OSHA Guidance– Recent OSHA guidance indicated that incentive programs that deny or decrease compensation based on the occurrence of work-related injuries discourages injury reporting. As such, the Committee removed the safety-based component of the AICP. However, as safety remains a core value of the Corporation, the Committee and the Board reserve the right to impose negative discretion on incentive awards depending on certain circumstances.


 

Commitment to Stockholder Engagement on Executive Compensation

In 2016, the Corporation engaged2017, we continued our long-standing engagement efforts with its largestour stockholders both during and outside of the proxy season. In April 2016, we contacted stockholders representing more than 50%each of our outstanding stock andthe last two years, we've met with or held telephonic meetings with stockholders holding approximately 25%.representing over 20% of our outstanding stock. These discussions held prior to our annual meeting, were focused primarily on howour business strategy and the alignment of our compensation program aligns withto our strategy and company performance. In November and December 2016, we contacted stockholders representing approximately 40% of our outstanding stock, and meetings were accepted by those representing approximately 15%. Many of ouraddition, some stockholders indicated they did not believe a call was necessary and indicated their support for our compensation and governance practices.

The Board, as well as management, prioritizes constructive communication with our investors to learn about their views of the Corporation and our governance and compensation practices. In addition to the frequent communication our CEO and Investor Relations team has with our stockholders, we maintainhave maintained ongoing dialogue with our largest stockholders regarding our corporate governance and executive compensation program since 2012. The feedback we receive from these discussions is carefully considered by the Board and the Committee, and we believe the strong support for our say-on-pay proposal over the last few years is evidence of the careful attention we pay to the feedback

given to us by our stockholders, and our ability to decisively take action and incorporate their perspectives in our programs.

Based on our 20162017 meetings, we determined

that our stockholders are supportive of the strong link between pay and performance embedded in our executive compensation program.

As a result of engagement with investors over Over the years, the Committee haswe have implemented changes to our compensation practices to further align pay with performance and enhanced disclosure regarding the rationale behind certain compensation decisions. For example, in 2014 we increased the weighting of performance awards in our long-term program to 60% and added ROCE as a second performance metric in the plan (in addition to TSR). These actions were taken in response to feedback we consistently heard from our stockholders that a larger percentage of equity awards should be performance-based and that the long-term program should include a capital return metric.

Executive Compensation in Detail

Compensation Principles

Our executive compensation program is designed to attract, reward and retain executives who make significant contributions through operational and financial achievement aligned with the goals and philosophy of our Carnegie Way transformation

and the long-term interests of stockholders. The following five principles support these objectives and guide the design of our compensation program:


Compensation Principle
Compensation Design
Align Pay with Stockholder Interests

  More than 73%

Approximately 60% of target compensation opportunity is performance based for our CEO (51%-67%(average of 44% for other NEOs).

Equity incentives comprise a significant portion of an executive’sexecutive's compensation.

Executives are subject to rigorous stock ownership and holding requirements.

Performance metrics, applied to 60% of our long-term program, align with our annual and long-term strategic objectives.

Pay Fair and Competitive Compensation

Executive compensation is targeted to be competitive with our peer group.

Our compensation programs are focused on objective corporate performance measures and individual performance.

Link PayCompensation to Company Performance and Strategy

Balance of compensation elements that focus on both short-term and long-term performance and goals.

Short-term incentives are based on annual financial performance (i.e., EBITDA and cash flow), and individual performance.

Long-term incentives are tied to the Corporation’sCorporation's relative TSR and return on capital employed (ROCE).

Retain Executives

Our long-term incentive grants include restricted stock units and performance awards that may retain some value in a period of stock market decline.

Equity-FocusProvide Equity-Focused and Tax-Efficient Rewards

The largest portion of an executive’sexecutive's compensation is in the form of long-term equity incentives, which preserves cash.

Our compensation programs are designed to preserve corporate tax deductions.

Compensation Program Elements

Short-Term Incentive Compensation

The purpose of our Annual Incentive Compensation Plan (AICP) is to align our executive officers’officers' compensation with the achievement of annual performance goals that support our business strategy. Typically, the short-term incentive awards are paid in cash, but the Committee retains discretion to provide the award in cash, stock, or a combination of both.

The AICP is designed to focus executives primarily on cash generation and profitability. It is funded each year based on the

the achievement of a pre-determined net sales performance goal, and once funded, actual amounts earned are based on the achievement of cash flow and earnings before interest, taxes, depreciation and amortization (EBITDA) performance measures. Final awards may be increased or decreased based on individual performance. The Committee determined that cash flow and EBITDA were the appropriate measures to drive the transformation required to achieve our goal of sustainable profitability.

Setting Corporate Performance Goals and Determining Results

In setting the goals under the AICP for 2016,2017, the Committee considered the Corporation’sCorporation's performance over the past five years, the businessannual operating plan for the year,2017, industry performance, and the Corporation’sCorporation's business transformation efforts. In general, the maximum performance goals were set at an amount that would require the Corporation to achieve a substantial level of Carnegie Way benefitsoperational improvements through asset revitalization and at a level that would generate sufficient earnings to pay the incremental cost of the incentive payments while

maintaining an equivalent amount of cash on the Corporation’sCorporation's balance sheet. The goals were considered a significant stretch given the challenging market conditions impacting the Corporation whenover the goals were setestablished in early 2016.

In addition to determining individual targets, the Committee approved EBITDA goals for each NEO. For the CEO CFO and general counsel,CFO, the EBITDA goal is based on the total company

Compensation Discussion and Analysis

results, which generally measures the operational results of all business segments. For executives assigned to a specific segment, the EBITDA goal is 50% based on the EBITDA goal for that segment and 50% based on total company

EBITDA (for Messrs.Mr. Matthews, and Bruno, this was the Flat-Rolled segment; for Mr. Rintoul, this was the Tubular segment; and for Mr. Buckiso, this was the European segment). This segment allocation of the EBITDA goal is intended to create stronger corporate, business segment and individual accountability by tying an executive’sexecutive's award to the performance of the segments for which he or she is directly responsible.

We concluded 20162017 with a total of $10.3$12.25 billion in net sales, therefore the award pool was funded for 20162017 because the net sales goal of $7$8.5 billion was achieved. The payout rate (prior to adjustment for individual performance) was determined based on achievement of the performance measures described in the table below. This payout rate demonstrates the performance alignment design of our plan. The 20162017 payout under the annual incentive compensation plan averaged 209%104% of target for our NEOs who received a payout, and the average payout for our NEOs over the last three years is 137%94% of target (in each case, including adjustments made for individual performance).

Individual Performance Goals and Results

In determining the CEO’sCEO's annual incentive, the Committee considers, among other things, the CEO’sCEO's individual performance in delivering results for the established value creation drivers of profitability, customer focus, operational excellence and high performing organization. The CEO’sCEO's individual performance objectives are reviewed by the Committee and approved by the Board. A similar evaluation is performed by the CEO with respect to all other executive officers using similar measures and objectives. The Committee sets performance goals for each annual period based on expected business results for the upcoming year, which are intended to be challenging stretch goals. The Committee uses its business judgment in reviewing each of these individual items and does not assign specific quantitative weighting to such items.

The following provides a brief summary of each NEO’sNEO's individual performance and contribution to the Corporation in 2016:

2017 considered by the Committee in determining each individual's performance modifier:

David Burritt – Mr. Burritt was named President & Chief Executive Officer on May 8, 2017, following his promotion to President & Chief Operating Officer on February 28, 2017. Since Mr. Burritt became CEO, U. S. Steel has delivered three consecutive quarters of reliable and consistent operational and financial results. As a result of these efforts, the Corporation's stock price at the end of the year was 165% of the stock price on the date that Mr. Burritt was promoted.

Mr. Burritt's intense focus on improvements to achieve operational excellence, not only improved financial flexibility and strengthened the balance sheet to reduce risk, but also enabled the Corporation to make strategic investments for our customers in Generation 3 Advanced High Strength Steels, Premium Connections, and facilitate future growth. The rewards of these strategies began to be realized in 2017 with a return to profitability for the first time since 2014, the best net debt since 2007, and the best liquidity since 2001.

Long-Term Incentive Compensation

Equity awards under the long-term incentive program (LTIP) are allocated among:

Performance-based awards (60% of LTIP award in 2016)
Stock options (20%)
Restricted stock units (RSUs) (20%)
Performance-based awards (60% of LTIP award in 2017)

Stock options (20%)

Restricted stock units (RSUs) (20%)

The Committee believes that these three long-term incentive vehicles best accomplish the objectives of aligning pay with performance and retaining executives. InOn February and May 2016,28, 2017, the Committee granted the long-term incentive awards set forth in the table below.

*In 2016, the Long-Term Incentive Award grant values were reduced. In order to avoid the potential of a windfall to executives that could result from awarding shares during a period of depressed stock price (which the Corporation experienced at the beginning of 2016 when the grant values were set), the Committee used an assumed higher share price when converting the grant value into shares to be awarded. As a result, the overall LTIP grant decreased by approximately 20% from 2015. Additionally, the performance awards were granted in February 2016, but the time-based stock options and RSUs were not granted until May 2016. Because of the bifurcated grant and because of the method used to reduce the grant value, the overall LTIP grants do not precisely align with the 60%, 20%, 20% structure described above.
**Mr. Bruno also received the second installment of his new-hire grant and a retention grant in 2016. These awards are not reported in this table, but are described under the heading “Other Awards” on page 33.

Performance-Based Awards (60% of LTIP Award Value)

Performance awards provide an incentive for executives to earn shares and cash based on our performance over a three-year performance period, with goals set at the beginning of each performance period. The performance awards do not pay dividends or carry voting privileges prior to vesting. In 2016,2017, the three-year performance period began on January 1, 2016,2017, and will end on December 31, 20182019 (the “2016"2017 Performance Period”Period"). The value of the performance awards granted under the 20162017 Performance Period was divided equally between relative TSR performance awards (which are equity-based) and ROCE performance awards.awards (which are cash-based). The three-year goals focus management on driving attractive returns on the capital we employ and on increasing stockholder value.

TSR Performance Awards

TSR performance awards are based on relative performance, with the payout determined based on the rank of the Corporation’sCorporation's TSR compared to the TSR of peer group companies over the three-year performance period.period (see the "Long-Term Incentive Plan Performance Peer Group" on page 38). TSR is determined based on the following formula: final price plus dividends per share for the performance period, divided by the initial price, raised to 1/3, minus 1. The initial price and final price used are the average closing price for the 20 business days prior to the first and last day of the performance period, respectively.

Beginning with the 2016 performance period, the Committee adopted a new peer group consisting of 12 domestic steel or steel-related companies for use in evaluating relative TSR (described in more detail under “Peer Group” beginning on page 35). In addition, the Committee approved a new policy beginning with 2016 grantsorder to address any potential pay for performance disconnect should the Corporation’sCorporation's TSR be negative over the performance period (regardless of relative performance). payouts may be capped as follows:

Payout is capped at target if the Corporation’s TSR is 0% to -5% on a compound annual growth rate (“CAGR”) basis;
Payout is capped at threshold if the Corporation’s TSR is lower than -5% to -10% on a CAGR basis; and
Payout is capped at target if the Corporation's TSR is 0% to -5% on a compound annual growth rate ("CAGR") basis;

Payout is capped at threshold if the Corporation's TSR is between -5% to -10% on a CAGR basis; and

ROCE Performance Awards

The payout is determined based on our weighted average cost of capital (noted as return on capital employed or “ROCE”"ROCE"), over the three-year performance period. ROCE is measured based on our consolidated worldwide EBIT, as adjusted, divided by our consolidated worldwide capital employed, as adjusted, over the three-year performance period. The weighted average ROCE is a three-year performance metric calculated based on the ROCE achieved in the first, second, and third years of the performance period, weighted at 20%, 30%, and 50% respectively.

the target level, and 200% at the maximum level. ROCE performance goals are not disclosed during an ongoing performance period due to competitive reasons. Beginning in 2015, the ROCE awards were granted in cash, rather than shares, to mitigate dilutive effects of a share grant.

20142015 Performance Awards

The performance period for the 20142015 performance awards ended on December 31, 2016.2017. The value of the 20142015 performance awards was equally divided between relative TSR performance awards and ROCE performance awards. While the relative TSR performance met the performance goals, the ROCE performance did not, resulting in an overall payout of 75%37% of the target award. Each of the relative TSR and ROCE goals, results and payouts are described below.

20142015 TSR Performance Awards

The Corporation’sCorporation's relative annualized TSR compared to the selected peer group for the performance period was at the 75th44th percentile, and resulted in a payout of 150%74% of the target award. The payout for our NEOs is shown below. Messrs. Bradley and Soni did not receive a payout because they were not employed by the Corporation when the grant was made. Mr. BrunoBuckiso did not receive a payout because he was not yet employed byeligible for TSR shares when the Corporation when the2015 grant was made.

Compensation Discussion and Analysis

Restricted Stock Units (20% of LTIP Award Value)

Restricted stock units (RSUs) are awards that deliver shares of common stock and accumulated dividends upon vesting. Restricted stock unitsRSUs generally vest ratably on each of the first, second and third anniversaries of the grant date, subject to the executive’sexecutive's continued employment on each vesting date.

The Committee believes that restricted stock unitsRSUs provide the best retention benefits among our long-term incentives, especially during times of challenging economic and industry conditions. They also enable our executives to build ownership in the Corporation, which addresses a key compensation objective. Additionally, because of the downside risk of owning stock, restricted stock units discourage executives from taking excessive risks that would not be in the best long-term interest of stockholders.

Stock Options (20% of LTIP Award Value)

Stock options are “at-risk”"at-risk" awards that reward executives for an increase in the Corporation’sCorporation's stock price over the term of the

option. The value of the options is limited to the appreciation of our stock price, if any, above the option’soption's exercise price after the option becomes exercisable and before it expires. Stock options are:

exercisable for a term of ten years;
subject to ratable vesting on each of the first, second and third anniversaries of the grant date; and
subject to continued employment on each vesting date.

exercisable for a term of ten years;

subject to ratable vesting on each of the first, second and third anniversaries of the grant date; and

generally subject to continued employment on each vesting date.

On May 31, 2016,February 28, 2017, the Committee granted traditional stock options with an exercise price based on the fair market value on the date of grant, which was $14.78.$39.265.

Other Awards

Mr. Bradley received a one-time cash award of $125,000 as part of his new-hire incentive. In February 2016,January 2017, Ms. Folsom was granted 10,000 RSUs with a three-year cliff vesting schedule. As part of her separation agreement, the Committee accelerated the vesting of that award. In 2017, Mr. BrunoSoni received a cash award of $30,000, which was the second-installment of a new hire incentive.

Changes to the 2018 Compensation Program

Added Cash Conversion Cycle as an AICP Metric : In recognition of the Corporation's intense focus on cash efficiency, the Committee decided to replace the AICP Cash Flow metric with Cash Conversion Cycle (CCC). This metric is measured in days. EBITDA remains the second installmentAICP metric.

Changed Weighting of his new hire grant of equity which consisted of 27,450 restricted stock units. Additionally in 2016, Mr. Bruno received a retention grant of equity consisting of 16,915 restricted stock units. In each caseAICP Metrics: The Committee rebalanced the RSUs cliff-vest on the third anniversaryweighting of the grant date.

two metrics under the AICP to 70% EBITDA and 30% CCC. Previously EBITDA and Cash Flow were equally weighted.


Elimination of Stock Options from LTIP: The Committee eliminated stock options from the types of awards granted as part of the 2018 annual long-term awards. The annual awards for 2018 are composed of 40% RSUs and 60% performance awards (30% based on TSR, and 30% based on ROCE). Stock options previously made up 20% of the long-term grant.

Long-Term ROCE Performance Awards to be Granted in Stock: Half of the long-term performance awards are based on our ROCE metric. Since 2015 these awards have been granted in and pay out in cash. For 2018, the Committee granted these awards in equity to further align executive compensation with stockholder interests.

Revised Long-Term TSR Goals:The Committee revised the goals for the long-term TSR metric. The Committee believes the goals remain rigorous, as they still require above-market performance to achieve target payout. The revisions better align with the Committee's objective of providing long-term compensation that is both rigorous but achievable.

Fixed Compensation and Benefits

Compensation Discussion and Analysis

Fixed Compensation and Benefits

Base Salary

Base salary is designed to compensate for the required day-to-day activities and responsibilities of each position. Base salary is set at a market competitive level to enable the Corporation to attract and retain talent. Actual salary levels take into account such factors as the contribution of the incumbent, individual qualifications and experiences, and internal value to the Corporation. Base salary is paid in cash.

Benefits

NEOs participate in many of the benefits provided to non-represented employees generally, including vacation and holiday benefits, insurance benefits, disability benefits, and medical and prescription drug programs. We believe these benefits support our overall retention objectives.

Compensation Discussion and Analysis

Retirement Programs

We provide the retirement benefits described below in order to attract and retain talented executive officers. We believe our retirement programs are reasonable in light of competitive pay practices and the total compensation of our executives.

Tax-Qualified Plans

The Corporation maintains the following tax-qualified retirement programs (together, the “Qualified Plans”"Qualified Plans"):

United States Steel Corporation Plan for Employee Pension Benefits, Revision of 2003 (the “Pension Plan”), which is a defined benefit plan; and
United States Steel Corporation Savings Fund Plan for Salaried Employees (the “Savings Plan”), which is a 401(k) defined contribution plan.

United States Steel Corporation Plan for Employee Pension Benefits, Revision of 2003 (the "Pension Plan"), which is a defined benefit plan; and

United States Steel Corporation Savings Fund Plan for Salaried Employees (the "Savings Plan"), which is a 401(k) defined contribution plan.

Participation in the Pension Plan was closed to new entrants on July 1, 2003 and benefits under the plan were frozen for all non-represented participants on December 31, 2015. Mr.Messrs. Matthews wasand Buckiso were the only NEONEOs covered by the Pension Plan and the related non-qualified plansNon Tax-Qualified Pension Plan described below. Mr. Matthews is the only NEO covered by the Supplemental Pension Program described below. Beginning in 2016, for all non-represented employees, the Corporation makes a contribution to a “Retirement Account”"Retirement Account" under the Savings Plan, which is in addition to any matching contributions made under the Savings Plan. Prior to 2016, non-represented employees who were covered by the Pension Plan were not eligible to receive Retirement Account contributions.

In 2016,2017, all of the NEOs received matching contributions and Retirement Account contributions under the Savings Plan and participated in the related non-qualified plans described below.

Non Tax-Qualified Plans

The Corporation maintains the following non tax-qualified programs (together, the “Non-Qualified Plans”"Non-Qualified Plans") that are designed to provide retirement benefits to executives and other high-level employees of the Corporation and its affiliates:

United States Steel Corporation Non Tax-Qualified Pension Plan (the “Non"Non Tax-Qualified Pension Plan”Plan");
United States Steel Corporation Executive Management Supplemental Pension Program (the “Supplemental Pension Program”);
United States Steel Corporation Supplemental Thrift Program (the “Supplemental Thrift Program”);
United States Steel Corporation Non Tax-Qualified Retirement Account Program (the “Non Tax-Qualified Retirement Account Program”); and
United States Steel Corporation Supplemental Retirement Account Program (the “Supplemental Retirement Account Program”).



United States Steel Corporation Executive Management Supplemental Pension Program (the "Supplemental Pension Program");

United States Steel Corporation Supplemental Thrift Program (the "Supplemental Thrift Program");

United States Steel Corporation Non Tax-Qualified Retirement Account Program (the "Non Tax-Qualified Retirement Account Program"); and

United States Steel Corporation Supplemental Retirement Account Program (the "Supplemental Retirement Account Program").

Benefits under the Non Tax-Qualified Pension Plan and Supplemental Pension Program were frozen on

December 31, 2015 when the tax qualified Pension Plan was frozen for all non-represented participants.

The purpose of the Non Tax-Qualified Pension Plan, the Supplemental Thrift Program, and the Non Tax-Qualified Retirement Account Program is to provide benefits that are not permitted to be provided under the Qualified Plans due to certain limits under the Internal Revenue Code. The benefit accrual formulas under these Non-Qualified Plans are approximately equal to the formulas under the respective Qualified Plans.

The purpose of the Supplemental Pension Program and the Supplemental Retirement Account Program is to provide pension benefits based upon compensation paid under our short-term incentive compensation plans, which is excluded under the Qualified Plans. We provide a retirement benefit based on incentive pay to enable our executives (who receive more of their pay in the form of incentive compensation) to receive a comparable retirement benefit.

Benefits under the Supplemental Pension Program and the Supplemental Retirement Account Program are subject to service-based and age-based restrictions. Unless the Corporation consents, benefits under the Supplemental Pension Program are not payable if the executive voluntarily terminates employment (1) prior to age 60 or before completing 15 years of service, or (2) within 36 months of the date coverage under the program commenced. Similarly, unless the Corporation consents, benefits under the Supplemental Retirement Account Program are not payable if the executive voluntarily terminates employment (1) prior to age 55 or before completing 10 years of service (or, if earlier, attaining age 65), or (2) within 36 months of the date coverage under the program commenced. We believe that these restrictions help to support our retention objectives.

For more information on our retirement programs, see thePension Benefitstable andNon-Qualified Deferred Compensation table later in this proxy statement.

Perquisites and Security

As part of the Carnegie Way initiative,In 2014, we examined the perquisites that historically have been offered to executives, and have eliminated or reduced many of them, and none have been extended to any executive hired after November 2014. We continue to provide a limited number of reasonable perquisites

as a recruiting and retention tool and to ensure the health and safety of our key executives. The perquisites available to our NEOs in 20162017 are described in the footnotes to the Summary Compensation Table on page 40 of this proxy statement. In general, the perquisites:

facilitate the ability of our executives to do their jobs without undue distractions or delays;
have clear business-related purposes;
ensure accurate personal tax reporting of the financial intricacies of our compensation programs; and
provide a measure of security unavailable elsewhere.

of commercial and other business relationships, provide a significant benefit to the Corporation and its stockholders. The perquisites provided to the NEOs in 2016, other than the CEO, were limited to tax preparation and financial planning and relocation benefits.

The perquisites we provide include residential and personal security services to employees who are the subject of a credible and specific threat on account of his or her role with the Corporation. The level of security provided depends upon the nature of the threat. In 2016, Mr.2017, Messrs. Longhi, was the only NEO who wasBurritt and Buckiso were provided with security services. The Board believes that providing personal security in response to threats arising because of employment by the Corporation is business-related.

We do not provide gross-up payments to cover personal income taxes that may be attributable to any of the perquisites except for (a) relocation, and (b) tax equalization and (c) expenses and travel related to expatriate assignments. These gross-ups are also provided to non-executive employees.

Change in Control Arrangements

The Corporation’sCorporation's Change in Control Severance Plan (the “CIC Plan”"CIC Plan") became effective on January 1, 2016, and generally provides for the payment of severance benefits to certain eligible executives, including each of the named executive officers, in the event their employment with the Corporation terminates involuntarily following a change in control of the Corporation. The Corporation previously maintained individual change in control agreements with certain executives. The CIC Plan supplanted the agreements, but provides for substantially similar terms.

The CIC Plan enables our executives to evaluate corporate transactional opportunities that may be in the best interests of the Corporation’sCorporation's stockholders, while limiting concerns about the potential impact of such opportunities on their job security. Under the CIC Plan, payments require a “double"double trigger," meaning the named executive officer is eligible for change in control severance payments and benefits in the event that he or she is terminated without cause or voluntarily for good reason in connection with a change in control. In general, upon a change in control and termination each of our named executive officersNEOs are entitled to a payment equivalent to a multiple of his or her salary and bonus..annual incentive award For Messrs. Longhi and Burritt and Ms. Folsom,Bradley, the severance payment multiple is 2.5x and for Messrs. Matthews, Rintoul, Buckiso is 2x and Brunofor Mr. Soni is 2x.1x. Neither Mr. Longhi nor Ms. Folsom are entitled to a change in control severance payment following termination of employment with the Corporation. We do not

provide gross-up payments to cover personal income taxes that may be attributable to payments under the CIC Plan. See “Potential"Potential Payments Upon Termination or Change in Control”Control" for additional information regarding the quantification of these potential payments and benefits.

Letter Agreements

In general, the Corporation does not enter into long-term employment agreements with its executives, but may enter into agreements for a limited period of time to attract or retain experienced professionals for high level positions. TheUnder the terms of his offer of employment, Mr. Bradley is entitled to a severance payment of two times his annual base salary and target bonus if he is terminated without cause prior to July 27, 2019. Under the terms of a letter agreement with Mr. Buckiso which expires on November 20, 2018, Mr. Buckiso may become entitled to a payment of up to three and a half times his salary and target annual incentive award upon the occurrence of certain events.

Separation Agreements

In connection with his retirement, Mr. Longhi entered into a separation agreement with the Corporation, doesproviding for, among other things, pro rata vesting of certain equity grants made in 2015 and 2016. Under his agreement and because Mr. Longhi was not have any current agreementsemployed for at least six months after the 2017 annual award grant date, Mr. Longhi forfeited the entirety of his 2017 long-term incentive awards. Under the agreement, Mr. Longhi agreed to a general release of claims, and non-solicitation, non-competition and non-disparagement provisions. In connection with its NEOs.her resignation from the Corporation, Ms. Folsom entered into a separation agreement providing for, among other things, (i) pro-rata vesting of various outstanding annually-granted performance awards, restricted stock unit grants and stock option awards; (ii) accelerated vesting of 10,000 restricted stock units that otherwise would not be vested as of her resignation; and (iii) cash payment of $1,260,000 in 12 installments and $50,000 in lieu of outplacement services. Under the agreement, Ms. Folsom agreed to a general release of claims, and non-solicitation, non-competition and non-disparagement provisions.


The Compensation Process

The Compensation Process

Independent Consultant and Management Input

The Committee retained Pay Governance, LLC as its independent consultant to assist in the evaluation of executive compensation programs and in setting executive officers’officers' compensation. The use of an independent consultant provides additional assurance that the Corporation’sCorporation's executive compensation programs are reasonable and consistent with the Corporation’sCorporation's objectives. The consultant reports directly to the Committee and does not perform services for management without the express approval of the Committee. There were no services performed by the consultant for management in 2016.2017.

The consultant regularly participates in Committee meetings, including executive sessions, and advises the Committee with respect to compensation trends and best practices, plan design, and the reasonableness of individual compensation awards.

With respect to the CEO’sCEO's compensation, the Committee makes its determinations based upon its evaluation of the CEO’sCEO's performance and with input from its consultant. Each year, the Committee reviews with the Board of Directors the CEO’sCEO's goals and objectives, and the evaluation of the CEO’sCEO's performance

with respect to the prior year’s approved CEOyear's goals and objectives. The CEO does not participate in the

Tally Sheets

The Committee uses tally sheets to evaluate the total compensation and projected payments to the named executive officers under various termination scenarios. This analysis is undertaken annually to assist the Committee in determining whether the compensation package of each named executive officer is appropriately aligned with our compensation philosophy and the compensation practices of our peers.

For 2017, the Corporation has removed Johnson Controls Inc., Deere & Company, International Paper Company and PACCAR Inc. from the executive compensation benchmarking peer group. These companies no longer meet the revenue and other guidelines the Corporation uses to select peers.

New Long-Term Incentive Plan Performance Peer Group for 2016

In February 2016, the Committee approved the use of a second peer group that will be used for evaluating long-term performance. Therefore, beginning with the 2016 Performance Period, the Corporation will utilizeutilizes two peer groups as described below:

Executive Compensation Peer Group.
Executive Compensation Peer Group. The peer group below is used to benchmark and assess the competitiveness of the compensation of our named executive officers.

Performance Peer Group. The executive compensation peer group will continue to be used to benchmark and assess the competitiveness of the compensation of our named executive officers.
Performance Peer Group.The performance peer group, which is more industry focused, is used to evaluate the long-term performance of our company for purposes of the relative TSR performance award. The performance peer group is being utilized to evaluate our performance against a targeted group of companies in our industry that we believe we need to outperform to be successful over the long term.

We created the new performance peer group, because executive compensation arrangements and practices are influenced by business complexity and company size, and manywhich is more industry focused, is used to evaluate the long-term performance of our company for purposes of the relative TSR performance award. The performance peer group is being utilized to evaluate our performance against a targeted group of companies in our industry competitorsthat we believe we need to outperform to be successful over the long term.

Long-Term Incentive Plan Executive Compensation Peer Group

The Executive Compensation peer group is used to serve as a market reference when making compensation decisions

and designing program features and assess the competitiveness of each element of compensation and compensation in total. We also use this peer group as a reference when analyzing pay-for-performance alignment.

The Executive Compensation Peer Group was selected based on the following criteria:

large companies primarily from the Materials sector or Industrials sector within the Global Industry Classification Standard (GICS) classification codes

companies similar in complexity – specifically, companies that have:

revenues that range from half to double that of the Corporation;

capital intensive businesses as indicated by lower asset turnover ratios;

market capitalization reasonably aligned with the Corporation; and

similar employee levels

acceptable levels of financial and stockholder performance and a higher company stock price volatility (referred to as "beta") to align with that of the Corporation

elimination of companies with unusual compensation practices (e.g., company founders who receive little or no compensation and companies that are much smaller than U. S. Steel. subsidiaries of other companies)

In setting the executive compensation peer group, the Committee considered a set of broader, industrial peers who might compete with the Corporation for talent as well as companies outside of the material/industrial industry who might attract our executives that have skills transferable outside of the metals industry.

Compensation Discussion and Analysis

For 2018, Alcoa Corp. was added to the executive compensation peer group.

Long-Term Incentive Plan Performance Peer Group

The Committee believes the use of a performance peer group is appropriate because executive compensation arrangements and practices are influenced by business complexity and company size, and many of our industry competitors are much smaller than U. S. Steel.

The performance peer group consists of twelve domestic companies in the steel industry. The use of a second peer group or index for evaluating TSR is a common practice among our peers. Because steel industry companies have traded differently from many of our large industrial peers since 2012, the use of a second peer group is more appropriate when evaluating relative TSR performance. Peers were selected based on criteria that included:

specific domestic steel or steel-related industry;
five-year stock price correlation greater than 0.50; and
stock price beta greater than 1.0.

Anti-Hedging and Pledging

We have a policy that prohibits all directors and employees, including the named executive officers, from engaging in any transaction that is designed to hedge or offset any decrease

in our stock price. Our anti-pledging policy prohibits directors and executive officers, including the named executive officers, from pledging our stock as collateral for a loan or holding shares in a margin account.

Clawback Policy

The Board has adopted a policy setting forth procedures to recover payment if an executive engaged in any fraud or misconduct, including gross negligence that caused or partially caused the need for a material restatement of the Corporation’sCorporation's publicly filed financial results. For any periods as to which a performance-based award was paid or credited to the executive, such award shall be subject to reduction, cancellation or reimbursement to the Corporation at the Board’sBoard's discretion. This policy is set forth in our Corporate Governance Principles which are available on our website www.ussteel.com.

Compensation Discussion and Analysis

Compensation and Risk Management

The Committee’sCommittee's compensation consultant annually performs a risk assessment of our executive compensation program and, based on its most recent review, the consultant has determined that our compensation program contains a variety of features that mitigate unnecessary risk taking, including the following:

Compensation Mix: Executive officers receive a mixture of short-term and long-term incentives in addition to base salary. Long-term incentives, which are paid mostly in equity, make up the majority of our executives’ compensation;
Capped Awards: Payments under our short-term incentive plan are capped at 227% of target and our performance awards are capped at 200% of target;
Performance Metrics: Different metrics are used in the short-term and long-term incentive programs; and
Stock Ownership: Executive officers are required to own a significant amount of common stock determined as a multiple of their salary midpoint.

not reasonably likely to create a risk that could have a material adverse effect on the Corporation.

Accounting and Tax Considerations

In determining executive compensation, the Committee considers, among other factors, the possible tax consequences to the Corporation. Tax consequences, including but not limited to tax deductibility by the Corporation, are subject to many factors (such as changes in the tax laws and regulations or interpretations thereof) that are beyond the control of the Corporation. In addition, the Committee believes that it is important for it to retain maximum flexibility in designing compensation programs that meet its stated objectives. For these reasons, the Committee, while considering tax deductibility as one of the factors in determining compensation, does not limit compensation to those levels or types of compensation that will be deductible by the Corporation. For a detailed discussion of the accounting impacts on various elements of long-term incentive compensation, see footnote 14 to the Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 20162017 filed with the SEC on February 28, 2017.21, 2018.

(1)
AICP refers to the Corporation's Annual Incentive Compensation Plan. LTIP refers to the Long-Term Incentive Compensation Program under the United States Steel Corporation 2005 Stock Incentive Plan and the United States Steel 2016 Omnibus Incentive Compensation Plan.

(2)
The grant date for the AICP represents the date that the Compensation & Organization Committee (the "Committee") established the annual incentive targets for the 2017 performance period.

(3)
Our NEOs received non-equity incentive awards under the AICP and LTIP in 2017. For a discussion of the plans, the 2017 performance targets and the 2017 award amounts, see the Short-Term Incentive Compensation and Long-Term Incentive Compensation sections in the "Compensation Discussion and Analysis" included in this proxy statement. Amounts shown reflect the amount that would be paid to each executive at each performance level, before consideration of individual performance.

(4)
The threshold level for the AICP award is based upon the lowest possible payouts for earnings before interest, taxes, depreciation, and amortization (EBITDA) (25% of target) and cash flow (25% of target) for a combined threshold of 50%. In addition, individual performance is also considered and can increase an award by up to 30% or reduce or eliminate the award. The threshold level for the LTIP grant is based on 50% of the incentive target performance for return on capital employed (ROCE) performance award described in footnote 6.

(5)
The maximum level for the AICP award is based on 175% of the target award multiplied by the maximum personal performance adjustment of 130%. The maximum award under the LTIP ROCE performance awards is 200% of the target award.

(6)
Performance award grants were made on February 28, 2017 to all NEOs except for Mr. Bradley, whose award was granted on August 1, 2017, shortly following his date of hire. For 2017, performance awards represent approximately 60% of the total annual grant value, with half of the award value granted in cash long-term incentives based on the Corporation's three-year weighted average return on capital employed (ROCE) as the performance measure, and the other half of the award value granted in equity based on total shareholder return (TSR). ROCE weighted average return is based on 20% weighting of year one of the performance period, 30% weighting on the second year of the performance period and 50% weighting on the third year of the performance period. Vesting is performance-based and will occur, if at all, following the end of the three-year performance period (the "performance period") on the date the Committee meets to determine the Corporation's actual performance for the performance period. The payout is based upon the three-year weighted average ROCE for the period for the cash portion, and the rank of our TSR compared to the TSR of the companies in the peer group for the equity portion. Performance awards do not pay dividends or carry voting privileges. Executives may receive grants of options and restricted stock units in addition to performance awards under the LTIP. We have not engaged in any repricing or other material modification of any outstanding options or other equity-based award under the plan.

(7)
Restricted stock unit grants were made on February 28, 2017 to all NEOs except Mr. Bradley. The units are time-based awards subject to ratable vesting over a three-year period with one-third of the granted shares vesting on February 28, 2018; an additional one-third of the shares vesting on February 28, 2019; and the remaining one-third of the shares vesting on February 28, 2020, subject in each case to continued employment through the vesting dates. Additional RSU grants were made on May 31, 2017 to Mr. Burritt. The units are time-based awards subject to ratable vesting over a three-year period with one-third of the granted shares vesting on May 31, 2018; an additional one-third of the shares vesting on May 31, 2019; and the remaining one-third of the shares vesting on May 31, 2020, subject in each case to continued employment through the vesting dates. Restricted stock unit grants were made on August 1, 2017 to Mr. Bradley. The units are time-based awards subject to ratable vesting over a three-year period with one-third of the granted shares vesting on August 1, 2018; an additional one-third of the shares vesting on August 1, 2019; and the remaining one-third of the shares vesting on August 1, 2020, subject in each case to continued employment through the vesting dates.

(8)
Option grants were made on February 28, 2017 to all NEOs except Mr. Bradley. The option grants are time-based, with a ten-year term and vest over a three-year period with one-third of the granted shares vesting on February 28, 2018; an additional one-third of the shares vesting on February 28, 2019; and the remaining one-third of the shares vesting on February 28, 2020, subject in each case to continued employment on the vesting dates. Additional option grants were made on May 31, 2017 to Mr. Burritt. The option grants are time-based, with a ten-year term and vest over a three-year period with one-third of the granted shares vesting on May 31, 2018; an additional one-third of the shares vesting on May 31, 2019; and the remaining one-third of the shares vesting on May 31, 2020, subject in each case to continued employment on the vesting dates. Option grants were made on August 1, 2017 to Mr. Bradley. The option grants are time-based, with a ten-year term and vest over a three-year period with one-third of the granted shares vesting on August 1, 2018; an additional one-third of the shares vesting on August 1, 2019; and the remaining one-third of the shares vesting on August 1, 2020, subject in each case to continued employment on the vesting dates.

(9)
Exercise Price of Option Awards represents the fair market value on the date of grant.

(10)
This column represents the full grant date fair market value for the equity incentive awards, stock awards and option awards, calculated in accordance with ASC 718 based on the average of the high and low stock price on the date of the grant. The restricted stock units accrue dividends at a non-preferential rate ($0.05) per share (as of the last announced dividend) that are paid when the underlying restricted stock units vest. The value of these dividends is reflected in the fair market value of the restricted stock unit grant. Restricted stock units carry no voting privileges. The target number of TSR performance awards is also based on the fair market value on the date of grant and includes a factor predicting the probable outcome of the performance goal for the grant. The factor for the February 28, 2017 performance award grant was 126.0185%, the factor for the May 31, 2017 performance award grant was 88.5801%, and the factor for the August 1, 2017 performance award grant was 86.9257% as determined by a third-party consultant using a Monte Carlo valuation model. The maximum payout for the ROCE performance awards is 200% of target. Accordingly, if maximum share payouts were achieved for such performance awards, the aggregate grant date fair value for such awards would be twice the target amount disclosed in the table related to such performance awards. The value shown for Ms. Folsom includes the incremental value attributed to the change in vesting terms of her January 2017 grant.

The target number of TSR performance awards is also based on the fair market value on the date of grant and includes a factor predicting the probable outcome of the performance goal for the grant. The factor for the 2015 performance award grant was 117.0849%, determined by a third-party consultant using a Monte Carlo valuation model. The maximum payout for the ROCE performance awards is 200% of target.

(4)The 2014 LTIP award was an equity-based award, split equally between relative TSR and ROCE performance metrics. The 2014 performance period ended on December 31, 2016. Using stock prices and dividends reported since the beginning of the performance period, we estimate that, through December 31, 2016, the Corporation has performed at the 75th percentile relative to a peer group which resulted in a final award of 150% of target for the relative TSR portion. The 2014 ROCE equity award performance was below threshold; and is valued at zero as of December 31, 2016.

In 2015 and 2016, the performance LTIP was split between an equity award based on TSR relative to a peer group and a long-term performance cash award based on ROCE. Based on performance through December 31, 2016, the 2015 TSR equity award is performing at a level that would earn a payout at 135% of plan and based on the first year of the performance period, the 2016 TSR equity award is performing at a level that would earn a payout at 194% of target. The ROCE cash awards for 2015 and 2016 are not shown on this table and based on performance through year one and year two these awards are indicating below threshold results.

(5)
The performance LTIP was split between an equity award based on TSR relative to a peer group and a long-term performance cash award based on ROCE. The 2015 performance period ended on December 31, 2017. Using stock prices and dividends reported since the beginning of the performance period, we estimate that, through December 31, 2017, the Corporation has performed at the 44th percentile relative to a peer group which resulted in a final award of 74.07% of target for the relative TSR portion. The 2015 ROCE equity award performance was below threshold and is valued at zero as of December 31, 2017. Based on performance through December 31, 2017, the 2016 TSR equity award is performing at a level that would earn a payout at 200% of plan and based on the first year of the performance period, the 2017 TSR equity award is performing at a level that would earn a payout at 87.43% of target. The ROCE cash awards for 2015, 2016 and 2017 are not shown on this table. Based on performance through December 31, 2017 these awards are indicating below threshold results for 2015 and above target results for 2016 and 2017.

U. S. Steel Pension Plan and age 60 for the Non Tax-Qualified Pension Plan and the Supplemental Pension Program.

U. S. Steel Pension Plan

The United States Steel Corporation Plan for Employee Pension Benefits, Revision of 2003 (“("U. S. Steel Pension Plan”Plan") provides defined benefits for substantially all non-represented, domestic employees who were hired before July 1, 2003. Messrs. Burritt, Bradley, Rintoul, Longhi, Burritt, and BrunoSoni who were hired in 2013, 2017, 2007, 2012 2013, and 20142016 respectively, and Ms. Folsom, who was hired in 2014, are not participants in the U. S. Steel Pension Plan and the related nonqualified plans. Mr. Matthews is a participantand Mr. Buckiso are participants under the U. S. Steel Pension Plan and the related non-qualified plans.plans as noted under "Pension Plan Compensation" on page 55. Benefits under the U. S. Steel Pension Plan and the related non qualifiednon-qualified plans described below were frozen for all non-represented participants on December 31, 2015.

The U. S. Steel Pension Plan is designed to provide eligible employees with replacement income during retirement. The two primary benefits provided to non-represented employees are based on final earnings (the “Final"Final Earnings Benefit”Benefit") and career earnings (the “Career"Career Earnings Benefit”Benefit") formulas. Benefits may be paid as an actuarially determined lump sum in lieu of monthly pension payments. The Internal Revenue Code (the “Code”"Code") limits the amount of pension benefits that may be paid from tax-qualified pension plans.

The Final Earnings Benefit component is based on a formula using a specified percentage (dependent on years of service) of average monthly earnings which is determined from the


   United States Steel Corporation | 2017 Proxy Statement   |   43

Executive Compensation Tables

five consecutive 12-month calculation periods in which the employee’semployee's aggregate earnings were the highest during the last ten 12-month calculation periods of continuous service prior to retirement. Incentive compensation is not considered

when determining average monthly earnings. Eligibility for an unreduced Final Earnings Benefit under the U. S. Steel Pension Plan is based on attaining at least 30 years of credited service or at least age 62 with 15 years of credited service. In addition to years of service and earnings while employed by the Corporation, service and earnings for certain purposes include those accrued while working for certain affiliated companies.

The annual normal retirement benefit under the Career Earnings Benefit component is equal to 1.3% of total career earnings. Incentive compensation is not considered when determining total career earnings. Career Earnings Benefits commenced

prior to attaining normal retirement or age 62 with 15 years of service, but after attaining age 58, are subject to an early commencement reduction equal to one-quarter of one percent for each month the commencement of pension payments precedes the month in which the participant attains the age of 62 years and one month.years. Career Earnings Benefits commenced prior to attaining age 58 are based on 1.0% of total career earnings and subject to a larger early commencement reduction. If he had retired on December 31, 2016,2017, Mr. Matthews’Matthews' annual Career Earnings Benefits would have been reduced by 56.60%53.33%, and if Mr. Buckiso had retired on December 31, 2017, his annual Career Earnings Benefits would have been reduced by 58.88%.

Benefits accrued for each executive for the purpose of calculating both the Final Earnings and Career Earnings Benefits are limited to the executive’sexecutive's unreduced base salary and foreign service premium, if any, subject to the compensation limit under the Code.


U. S. Steel Pension Plan Calculation Assumptions

The present value of accumulated benefit obligations represents the actuarial value of benefits earned by the executives under the U. S. Steel Pension Plan. Assumptions used in the calculations include an unreduced benefit age of 62, the election of a lump sum option and estimatedcredited service, and career earnings and final average earnings as of December 31, 2015. Estimated finalFinal average earnings were developedis based on the average of the actual monthly salaries paid in the highest five

consecutive 12 month periodsperiod during the ten years preceding December 31, 2015.

The salary amounts include base salary, excluding incentive compensation. For these calculations, the executive’s unreduced base salary is used to the extent necessary to avoid the adverse effects of the temporary reduction in base salary that was effective between July 1, 2009 and July 1, 2010. The number of years of credited service in the 20162017 Pension Benefits table shows the number of years earned and used to calculate the accrued benefits reported.


Non Tax-Qualified Pension Plan

The purpose of the United States Steel Corporation Non Tax-Qualified Pension Plan (“("Non Tax-Qualified Pension Plan”Plan") is to compensate individuals for the loss of benefits under the U. S. Steel Pension Plan that occur due to certain limits established or required under the Code. The amount payable under the Non Tax-Qualified Pension Plan is equal to the difference between the benefits the executive actually receives under the U. S. Steel Pension Plan and the benefits that the executive would

have received under the U. S. Steel

Pension Plan except for the limitations imposed by the Code. Benefits under the Non Tax-Qualified Pension Plan were frozen on December 31, 2015.

Benefits paid under the Non Tax-Qualified Pension Plan are in the form of an actuarially determined lump sum payable to the executive upon termination of employment, subject to the six-month waiting period under Section 409A of the Code for specified employees.


Non Tax-Qualified Pension Plan Calculation Assumptions

 

The present value of accumulated benefit obligations represents the actuarial value of benefits earned by the executives under the Non Tax-Qualified Pension Plan and is based on the same provisions and eligibility status as

determined under the U. S. Steel Pension

Plan. Assumptions used in the calculations include an unreduced benefit age of 62, the election of a lump sum option and credited service, and estimated career earnings and final average earnings as of December 31, 2015.

Supplemental Pension Program

Table of Contents

Executive Compensation Tables

Supplemental Pension Program

The purpose of the United States Steel Corporation Executive Management Supplemental Pension Program (the “Supplemental"Supplemental Pension Program”Program") is to provide a pension benefit for executives and certain non-executives who participate in the U. S. Steel Pension Plan with respect to compensation paid under the short-term incentive compensation plans of the Corporation, its subsidiaries, and its joint ventures.Corporation. Benefits under the Supplemental Pension Program were frozen on December 31, 2015.

Executives with at least 15 years of continuous service become eligible to receive a benefit under the Supplemental Pension Program at retirement or termination of employment. Benefits will not be payable under the program with respect to an executive who (a) terminates employment prior to age 60 or (b) terminates employment within 36 months of the date coverage under the Supplemental Pension Program begins, unless, in either case, the Corporation consents to

the termination; provided, however, such consent is not required for terminations because of death or involuntary termination,

other than for cause. Distributions are subject to the six-month waiting period under Section 409A of the Code for specified employees.

An executive’sexecutive's average earnings are used to calculate the benefit under the Supplemental Pension Program and are defined as the average monthly earnings derived from the total short-term incentive (described as Non-Equity Incentive Plan Compensation in the Summary Compensation Table in this proxy statement) paid or credited to the executive under the Annual Incentive Compensation Plan with respect to

the three calendar years for which total short-term incentive payments were the highest out of the last ten consecutive calendar years prior to the executive’s termination. Short-term incentive payments payable for the calendar year in which termination occurs would be considered if such payment produces average earnings greater than that determined atexecutive's termination. Benefits are paid as an actuarially determined lump sum. Such lump sum cannot be less than the lump sum value determined using the executive’s highest monthly accrued benefit under the Supplemental Pension Program.


Supplemental Pension Program Calculation Assumptions

The present value of accumulated benefit obligations represents the actuarial value of benefits earned through December 31, 2015 by an executive under the Supplemental Pension Program. Assumptions used in the calculations

include a normal retirement age of 60, a lump sum payment,

and credited service and average earnings as of December 31, 2015. Credited service under the Supplemental Pension Program is the same as under the U. S. Steel Pension Plan.

Supplemental Thrift Program

The purpose of the United States Steel Corporation Supplemental Thrift Program (the “Supplemental"Supplemental Thrift Program”Program") is to compensate individuals for the loss of matching contributions by the Corporation under the U. S. Steel Savings Plan that cannot be provided due to the statutory limits on covered compensation (which limit was $265,000$270,000 in 2016)2017) and combined Corporation and individual annual contributions

(whichannual contributions (which limit was $53,000$54,000 in 2016)2017). Under the Supplemental Thrift Program, executives accrue benefits in the form of phantom shares of U. S. Steel common stock. In the aggregate, the benefit accruals under the Supplemental Thrift Program and the matching contributions under the U. S. Steel Savings Plan may equal up to 6% of the executive’sexecutive's eligible base salary.

Executive Compensation Tables

An executive receives a lump sum distribution of the benefits payable under this program upon his or her (a) termination of employment with five or more years of continuous service, (b) termination of employment, prior to attaining five years of

continuous service, with the

consent of the Corporation, or (c) pre-retirementbecause of death, subject to the six-month waiting period under Section 409A of the Code for specified employees.


Non Tax-Qualified Retirement Account Program

The purpose of the United States Steel Corporation Non Tax-Qualified Retirement Account Program is to compensate individuals for the loss of Retirement Account contributions that cannot be provided under the U. S. Steel Savings Plan due to the statutory limits on covered compensation (which was $265,000$270,000 in 2016)2017) and combined Corporation and individual annual contributions (which limit was $53,000$54,000 in 2016)2017). Retirement Account contributions are non-elective employer contributions that are in addition to the matching contributions made by the Corporation under the U. S. Steel Savings Plan. All of the NEOs participate in the the Non Tax-Qualified Retirement Account Program.

Under the Non Tax-Qualified Retirement Account Program, accrued benefits are recorded in a notional account and

credited with earnings as if the account had been invested

in the U. S. Steel Savings Plan. In the aggregate, benefit accruals under this program and the Retirement Account contributions under the U. S. Steel Savings Plan shall equal 8.5% of the executive’sexecutive's eligible base salary.

Benefits under this program are payable in a lump sum distribution following the termination of employment (a) after completing three years of continuous service, or (b) prior to completing three years of continuous service, with the consent of the Corporation; provided, however, such consent is not required for terminations because of death or involuntary termination, other than for cause. Payments are subject to the six-month waiting period under Section 409A of the Code for specified employees.


Supplemental Retirement Account Program

The purpose of the Supplemental Retirement Account Program is to provide Retirement Account contributions with respect to compensation paid under the short-term incentive

compensation plans of the Corporation, its subsidiaries, and its joint ventures. All of the NEOs participate in the program.

Potential Payments Upon Termination or Change in Control

Potential Payments Upon Termination or Change in Control

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The compensation and benefits payable to our executives upon termination vary depending upon the event triggering the termination and the executive’sexecutive's relevant employment facts at the time of termination. For purposes of the tables and discussions

and discussions included in this section, we have assumed the following termination scenarios (the column references are to the columns in the tables that follow):


Termination Scenarios

Voluntary Termination (with Consent) or Retirement –

Voluntary Termination (with Consent) or Retirement –(Column A)

This termination scenario assumes retirement pursuant to a retirement plan. Benefits under the Supplemental Pension Program are not payable to an executive who voluntarily terminates employment prior to age 60, unless the Corporation consents to such termination. We have assumed the Corporation’sCorporation's consent to retire prior to age 60 under this scenario; however, the Corporation usually reserves its consent for an executive who has served the Corporation well, is not leaving for an opportunity at another company, and is not leaving prior to the development of his or her successor.

With respect to long-term incentives, the Compensation & Organization Committee (the “Committee”"Committee") has discretion to terminate unvested awards upon termination. While the

Committee reserves the right to decide these matters on a case-by-case basis, its practice has been to prorate the vesting of the shares scheduled to vest during the current

vesting period for the time employed during the current vesting period (for example, in the case of stock options and restricted stock units, seventen months worked during the twelve-month vesting period from June 2016March 2017 to May 2017February 2018 would result in a vesting of seven-twelfthsten-twelfths of the number of shares scheduled to vest in May 2017,February 2018, with no such pro rata vesting for the shares scheduled to vest after May 2017)February 2018). Given our assumption under this scenario that the Committee has consented to the executive’sexecutive's retirement, the pro rata vesting discussed above has been applied to the calculations in the table below.tables below with the following exception. For the 2017 long-term incentive awards, the awards are fully vested if the executive attained age 60 with 5 years of service or age 65 prior to retirement, provided the executive is employed for at least six months following the date of grant and is not a participant in the Supplemental Pension Program.


Voluntary Termination (Without Consent) or Involuntary Termination (for Cause) – (Column

Voluntary Termination (Without Consent) or Involuntary Termination (for Cause) –(Column B)

This termination scenario assumes that the Corporation does not consent to an executive’sexecutive's voluntary termination of his or her employment prior to age 60, or that the Corporation terminates the executive’sexecutive's employment for cause. Under these conditions, the Committee is not likely to exercise any

discretion that it may

have in favor of the executive and, accordingly, we have not assumed the exercise of any discretion in favor of executives with respect to unvested awards for purposes of the calculations in the tables below.


Involuntary Termination (Not for Cause) – (Column

Involuntary Termination (Not for Cause) –(Column C)

Events that could cause the Corporation to terminate an executive’sexecutive's employment involuntarily, not for cause, include the curtailment of certain lines of business or a facility shutdown where the executive’sexecutive's services are no longer required due to business conditions or an organizational realignment. Prior to the involuntary termination, the executive may be eligible for benefits under our Supplemental Unemployment Benefit Program for

Non-Union Employees, which may include the payment of a percentage of base salary, basic life and health insurance. For purposes of determining the vesting of equity awards upon

termination, we have assumed the executive’sexecutive's employment was terminated on December 31, 2016.2017. Awards are prorated upon termination for purposes of the calculations in the tables below.below with the following exception. For the 2017 long-term incentive awards, the awards are fully vested if the executive attained age 60 with 5 years of service or age 65 prior to the involuntary termination, provided the executive is employed for at least six months following the date of grant and is not a participant in the Supplemental Pension Program.

Change in Control and Termination – (Column D)

Table of Contents

Potential Payments Upon Termination or Change in Control

Change in Control and Termination –(Column D)

All of the NEOs are covered by the Corporation’sCorporation's Change in Control Severance Plan (the “CIC Plan”"CIC Plan"), effective January 1, 2016, as described in the Compensation Discussion and Analysis insection of the proxy statement. In addition to the severance benefits paid pursuant to the CIC Plan, all long-term incentive awards would vest upon a change in control and a termination, and benefits would be paid according to each benefit plan’splan's provisions following the termination of an executive’sexecutive's employment in connection with a change in control. The following discussion describes the events and circumstances that would trigger payments under the CIC Plan.

Generally, payments are triggered upon the occurrence of both a Change in Control of the Corporation and termination of the executive’sexecutive's employment by the Corporation other than for cause.

Under the CIC Plan, each executive agrees to remain in the employ of the Corporation until the earlier of (i) a date three months after a Change in Control and (ii) a date six months after a Potential Change in Control (as defined below). Payments are also triggered if the executive terminates his or her employment for Good Reason (as defined below); however, in order for the Corporation to be obligated to pay the benefits under the contract, all Good Reason terminations must also involve an actual Change in Control (if the Good Reason termination occurs prior to a Change in Control, the Change in Control must be a 409A Change in Control; see definition below).


United States Steel Corporation | 2017 Proxy Statement   |47

Potential Payments Upon Termination or Change in Control

Following a Change in Control, if there is a termination by the Corporation (other than for Cause or Disability) or by the executive for Good Reason, the executive is entitled to the following benefits:

Accrued compensation and benefits;

Cash severance;

Supplemental Retirement Benefit;

Welfare Benefits;

Outplacement services;

Supplemental Savings Plan Benefit – equal to the unvested portion of the Corporation's contributions on behalf of the executive under the tax-qualified and non tax-qualified savings plans; and

Legal fees – reimbursement for legal fees incurred as a result of termination of employment and incurred in contesting or disputing such termination or seeking to enforce any right or benefit under the CIC Plan or in connection with any tax audit relating to Sections 4999 (excise taxes) or 409A (deferred compensation) of the Code.

A"Good ReasonReason" termination involves a voluntary termination following any of these events:

An executive is assigned duties inconsistent with his or her position;

Reduction in base salary;

Relocation in excess of 50 miles from the executive's current work location;
Failure to continue all of the Corporation's employee benefit, incentive compensation, bonus, stock option and stock award plans, programs, policies, practices or arrangements in which the executive participates or failure of the Corporation to continue the executive's participation therein at amounts and levels relative to other participants;

Failure of the Corporation to obtain agreement from any successor to the Corporation to assume and perform the CIC Plan; or

Any termination that is not effected pursuant to a Notice of Termination (a Notice of Termination is to be given by the Corporation in connection with any termination for cause or disability and the executive must give a notice of termination in connection with a termination for good reason).

An executive is assigned duties inconsistent with his or her position;
Reduction in base salary;
Relocation in excess of 50 miles from the executive’s current work location;
Failure to continue all of the Corporation’s employee benefit, incentive compensation, bonus, stock option and stock award plans, programs, policies, practices or arrangements in which the executive participates or failure of the Corporation to continue the executive’s participation therein at amounts and levels relative to other participants;
Failure of the Corporation to obtain agreement from any successor to the Corporation to assume and perform the CIC Plan; or
Any termination that is not effected pursuant to a Notice of Termination (a Notice of Termination is to be given by the Corporation in connection with any termination for cause or disability and the executive must give a notice of termination in connection with a termination for good reason).

A"Change in ControlControl" happens under the CIC Plan if any of the following occurs:

A person (defined to include individuals, corporations, partnerships, etc.) acquires 20% or more of the voting power of the Corporation;
A merger occurs involving the Corporation except (a) a merger with at least a majority of continuing directors or (b) a merger constituting the disposition of a division, business unit or subsidiary;
A change in the majority of the Board of Directors;
A sale of all or substantially all of the assets of the Corporation; or
Stockholder approval of a plan of complete liquidation.



A merger occurs involving the Corporation except (a) a merger with at least a majority of continuing directors or (b) a merger constituting the disposition of a division, business unit or subsidiary;

A change in the majority of the Board of Directors;

A sale of all or substantially all of the assets of the Corporation; or

Stockholder approval of a plan of complete liquidation.

A "Potential Change in Control" occurs if:

The Corporation enters into an agreement that would result in a Change in Control;
A person acquires 15 percent or more of the voting power of the Corporation;
There is a public announcement by any person of intentions that, if consummated, would result in a Change in Control; or
The Corporation’s Board of Directors passes a resolution stating that a Potential Change in Control has occurred.

The Corporation enters into an agreement that would result in a Change in Control;

A person acquires 15 percent or more of the voting power of the Corporation;

There is a public announcement by any person of intentions that, if consummated, would result in a Change in Control; or

The Corporation's Board of Directors passes a resolution stating that a Potential Change in Control has occurred.

A "409A Change in Control" is similar to a Change in Control, except that it meets the requirements of Section 409A of the Code. The main difference between the two definitions is that a 409A Change in Control requires a person to acquire 30% of the total voting power of the Corporation’sCorporation's stock, while a Change in Control requires a person to acquire 20% of the total voting power of the Corporation’sCorporation's stock. A 409A Change in Control must occur prior to any payment in the event the termination precedes the Change in Control. In other words, payments under the CIC Plan are due to the executive if:

there is an involuntary termination by the Corporation (other than for cause or disability) or a voluntary termination by the executive for Good Reason;

GRAPHIC     United States Steel Corporation  |  2018 Proxy Statement    |49


Table of Contents

there is an involuntary termination by the Corporation (other than for cause

Potential Payments Upon Termination or disability) or a voluntary termination by the executive for Good Reason;

the executive reasonably demonstrates that an Applicable Event (defined below) has occurred; and
a 409A Change in Control occurs within twenty-four months following the termination.

An “

the executive reasonably demonstrates that an Applicable Event (defined below) has occurred; and

a 409A Change in Control occurs within twenty-four months following the termination.

An"Applicable Event" (a term used for various purposes, including defining points at which compensation amounts and periods are measured) means a Change in Control, Potential Change in Control or actions of a third party who has taken steps reasonably calculated to effect a Change in

Control.

To the extent required by Section 409A of the Code, payments would be delayed six months following the applicable reference date.

As mentioned above, a “double trigger”"double trigger" must occur prior to the Corporation incurring any liability under the CIC Plan; that is, for there to be payments under the CIC Plan, both of the following must occur: (i) a termination and (ii) a Change in Control (or, in some cases, a 409A Change in Control).


Disability and Death

Disability and Death(Columns E and F)

Employees with at least 15 years of continuous service who are covered by the U. S. Steel Pension Plan and become totally and permanently disabled prior to age 65 are eligible to retire on a permanent incapacity pension. The criteria for a disability

termination under the Long-Term Incentive Compensation

Program are the same as for a disability termination under Section 409A of the Code. If an employee with at least 15 years of service dies while actively employed, benefits under the Corporation’sCorporation's qualified and non-qualified plans are calculated as if the employee had retired on the date of his or her death.

Potential Payments Upon Termination or Change in Control

Potential Payments Upon Termination Tables

The following tables were developed using the above termination scenarios, and an estimation of the amounts that would be payable to each NEO under the relevant scenario. A discussion of each of the types of compensation follows the tables. Amounts shown for Mr. Longhi and Ms. Folsom reflect actual amounts that they became entitled to at their termination of employment. Non-qualified retirement benefits and equity awards will be distributed six months after their termination dates. The estimated present values of the benefits provided to the NEOs under each of these termination scenarios were determined using the following assumptions:

1.
Unless otherwise noted, the tables reflect values as of December 31, 2017 that NEOs would have been entitled to, following, or in connection with a termination of

employment, with the triggering event occurring on December 31, 2017;

1.Unless otherwise noted, the tables reflect values as of December 31, 2016 that NEOs would have been entitled to, following, or in connection with a termination of employment, with the triggering event occurring on December 31, 2016;
2.
The stock price used for valuation purposes for the long-term incentive awards was the closing stock price on December 29, 2017, which was $35.19;

3.
The normal life expectancy obtained from the 1971 Group Annuity Mortality Tables, or, for a permanent incapacity type of pension, life expectancy obtained from the Disabled Life Expectancy Tables (wages and salaried) based on the Corporation's experience, made gender neutral on a nine to one male/female ratio; and

4.
The December 31, 2017 Pension Benefit Guaranty Corporation interest rate of 0.75% was used to determine 2017 lump sum payment amounts.

The term "with Consent" means consent with respect to each component of pay. This termination scenario typically involves retirement pursuant to a retirement plan or, if an NEO has not yet attained the necessary age and service requirements for retirement, a voluntary termination with consent.

(2)
The value shown for cash severance benefits represents the total that would be paid over a specified period. Cash severance amounts shown for Mr. Longhi and Ms. Folsom also include payments for accrued and unused vacation.

(3)
All benefit amounts would become payable on May 31, 2018 under a permanent incapacity pension, five months following a disabling event that occurred on December 31, 2017.

(4)
The annual restricted awards and option awards include pro rata vesting on each grant date anniversary. The retention award granted to Mr. Soni will vest 100% on the third anniversary of the date of the grant. The vesting of the restricted stock award granted in January 2017 to Ms. Folsom was accelerated upon her termination of employment.

(5)
Values shown for the Performance awards are calculated as follows:

The values shown for the 2015 equity award for TSR and the cash award for ROCE are based on the actual value at the end of the Performance Period on December 31, 2017.

The 2015 TSR grant finished the Performance Period at the 44th percentile of the peer group indicating a payout of 74.07% of the target number of shares. The 2015 ROCE grant ended the Performance Period with below threshold results indicating that the entire award will be forfeited.

The values shown for the 2016 and 2017 TSR equity and ROCE cash grants in columns A and C represent a pro-rated award based on the number of months worked during the performance period divided by the total number of months in the performance period multiplied by the expected performance through December 2017.

    (1)The term “with Consent” means consent with respect to each component of pay. This termination scenario typically involves retirement pursuant the performance period is ended on the date of the CIC and the actual performance is calculated based on the abbreviated Performance Period to determine the "Achieved Performance Award." The balance of the award if any is forfeited and the "Achieved Performance Award" remains subject to employment restrictions through the third anniversary date of the grant unless the Grantee's employment is terminated without cause after a retirement plan. Retirement is generally not applicable to the NEOs because they have not yet attained the necessary age and service requirements for retirement and, accordingly, the amounts set forth in this column are payable to them only in the event of a voluntary termination with consent.
    (2)The value shown for cash severance benefits represents the total that would be paid over a specified period.
    (3)All benefit amounts would become payable on May 31, 2017 under a permanent incapacity or a deferred vested pension, five months following a disabling event that occurred on December 31, 2016.
    (4)The annual restricted awards and option awards include pro rata vesting on each grant date anniversary, for February grants to NEOs there are ten months (March through December) and for May grants to NEOs there are seven months (June through December) counted toward service for the unvested portion of the stock option, or restricted stock unit awards under certain termination events. For the annual awards granted in January 2014 to Ms. Folsom, there are eleven months counted toward service for the unvested portion of the stock options, restricted stock unit and restricted stock awards under certain termination events. These terms also apply in the case of the retention restricted stock units granted to Mr. Bruno, except that the retention restricted stock units would also fully vest upon an involuntary termination by the Corporation other than for cause or a voluntary termination with consent, and would be forfeited upon retirement.

Potential Payments Upon Termination or Change in Control

Termination and Change-in-Control Provisions

Cash Severance

No cash severance payments are made with respect to an executive’sexecutive's termination of employment due to voluntary termination (with consent or retirement) (Column A), voluntary termination (without consent) or involuntary termination for cause (Column B), disability (Column E) or death (Column F).

Under our broad-based Supplemental Unemployment Benefit Program covering most non-represented employees, monthly cash benefits are payable to executives for up to 12 months (depending on years of service) while on layoff in the event of an involuntary termination not for cause (Column C).

Cash severance is one of the payments made to executives under the Change in Control Severance Plan in the event of a termination in connection with a Change in Control (Column D).

Under the plan, payment would be made in a lump sum amount equal to 2.5 times2.5x for Messrs. Longhi and Burritt and Ms. Folsom, and two timesBradley, 2x for Messrs. BrunoBuckiso, Matthews and MatthewsRintoul, and 1x for Mr. Soni the sum of (a) base salary and (b) the current target under the short-term incentive compensation program (or, if higher than the target, the average short-term incentive compensation for the prior three years).

The benefits under the Supplemental UnemployementUnemployment Benefits Program and the Change in Control Program are contingent upon the execution of an agreement which contains a general release of claims and confidentiality, non-disparagement and non-solicitation provisions.


Short-Term Incentive

Following a voluntary termination with the Committee’sCommittee's consent or a retirement pursuant to a retirement plan (Column A), a disability (Column E), or death (Column F), an executive would be entitled to receive a short-term incentive award if (a) the relevant performance goals are achieved, (b) the executive is employed for at least six months during the performance period, and (c) the Committee does not exercise its discretion to reduce or eliminate the award. For purposes of the short-term incentive program, retirement means a termination of employment after having completed 30 years of service, attainment of age 60 with 5 years of service, or attainment of age 65.

If an executive’sexecutive's employment terminates voluntarily without the Committee’sCommittee's consent or involuntarily (Columns B and C), regardless of whether the termination is for cause or not for cause, no short-term incentive award is payable.

Because the cash severance payment, discussed above, includes a multiple of the target short-term incentive, no payments are made pursuant to the short-term incentive program in the event of a Change in Control (Column D).


Stock Options

Following a voluntary termination with the Committee’sCommittee's consent or a retirement pursuant to a retirement plan (Column A), and subject to the Committee's discretion, (i) a prorated number of an executive’sexecutive's unvested stock options granted in 2015 and 2016 would vest based on the number of complete months worked during the vesting period subjectand (ii) the stock options granted in 2017 would fully vest if the executive attained age 60 with 5 years of service or age 65 prior to termination, provided the Committee’s discretion.executive is employed for at least six months following the date of grant and is not a participant in the

Supplemental Pension Program and partially vest after 30 years of service or after attainment of age 55 with 10 years of service. The remaining unvested options would be forfeited. In the event of a disability (Column E) or death (Column F), all unvested options vest immediately. All vested options granted under the current stock plan remain exercisable for three years (five years for options granted in 2017) after termination or, if less, until the original expiration date.

For involuntary terminations that are not for cause (Column C), we have assumed that the executive terminated employment on December 31, 20162017 and that a prorated number of options vested based on the number of complete months worked during the vesting year (May 2016(February 2017 to February 2018 for the 2017 grant, May 2017 to May 20172018 for the 2016 grant, and February 20152017 to February 20162018 for the 2015 grant and May 2014 to May 2015 for the 2014 grant).

Stock options include a “double-trigger”"double-trigger" and require a termination in connection with a Change in Control (Column D) in order for the vesting to be accelerated. Unvested stock options would not be forfeited if (i) employment is terminated during a potential change in control period by the Corporation for other than cause or disability or by the executive for good reason and (ii) a 409A Change in Control occurs within twenty-four months following the commencement of the potential change in control period.


Restricted Stock Units

Following a voluntary termination with the Committee’sCommittee's consent or a retirement pursuant to a retirement plan (Column A), and subject to the Committee's discretion, (i) a prorated number of an executive’sexecutive's unvested restricted stock units granted in 2015 and 2016 would vest based on the number of complete months worked during the vesting period subjectand (ii) the restricted stock units granted in 2017 would fully vest if the executive attained age 60 with 5 years of service or age 65 prior to termination, provided the Committee’s discretion.executive is employed for at least six months following the date of grant and is not a participant in the Supplemental Pension Program and partially vest after 30 years of service or after attainment of age 55 with 10 years of service. The remaining unvested restricted stock units would be forfeited. In the event of a disability (Column E) or death (Column F), all unvested restricted stock units vest immediately. As described in the footnotes to the table above, different provisions may apply in the case of retention restricted stock units granted to Mr. Bruno.

If an executive’sexecutive's employment terminates voluntarily without the Committee’sCommittee's consent or involuntarily for cause (Column B), all remaining unvested restricted stock units are forfeited.

For involuntary terminations that are not for cause (Column C) we have assumed that the executive terminated employment on December 31, 20162017 and that a prorated number of restricted stock units vested based on the number of complete months worked during the vesting year (May 2016(February 2017 to February 2018 for the 2017 grant, May 2017 to May 20172018 for the 2016 grant, February 20152017 to February 20162018 for the 2015 grant and May 2014 to May 2015 for the 2014)grant).

Potential Payments Upon Termination or Change in Control

Restricted stock units require a termination in connection with a Change in Control (Column D) in order for the vesting to be accelerated. Unvested restricted stock units would not be forfeited if (i) employment is terminated during a potential

change in control period by the Corporation for other than cause or disability or by the executive for good reason and (ii) a 409A Change in Control occurs within twenty-four months following the commencement of the potential change in control period.


Performance Awards

Following a voluntary termination with the Committee’sCommittee's consent or a retirement pursuant to a retirement plan (Column A), and provided that the relevant performance goals are achieved, (i) the prorated value of the performance awards granted in 2015 and 2016 would vest based on the number of complete months worked during the relevant performance period (each is approximately three years), and (ii) the performance awards granted in 2017 would fully vest if the executive attained age 60 with 5 years of service or age 65 prior to termination, provided that the relevant performance goals are achieved.executive is employed for at least six months following the date of grant and is not a participant in the Supplemental Pension Program and partially vest after 30 years of service or after attainment of age 55 with 10 years of service. For performance awards for which the performance goals are achieved, a modified proration is used in the event of a death (Column F) or disability (Column E) allowing 0% of the achieved award if such event occurs prior to the completion of the first third of the performance period, 50% of the achieved award if such event occurs on or after completion of the first third, but prior to completion of the second third, of the performance period, and 100% of the achieved award for events occurring on or after completion of the second third of the performance period.

This modified proration effectively shortens the post-termination waiting period to a maximum of two years, thereby allowing an estate to potentially close within two years, since there would be no value allowed for performance awards granted within one year of a participant’sparticipant's death.

If an executive’sexecutive's employment terminates voluntarily without the Committee’sCommittee's consent or involuntarily for cause (Column B), all remaining unvested performance awards are forfeited.

For involuntary terminations that are not for cause (Column C) we have assumed that the executive terminated employment on December 31, 20162017 and that a prorated number of performance awards vested based on the number of complete months worked during the relevant performance period.

Performance awards require a termination in connection with a Change in Control (Column D) in order for the vesting to be accelerated. For these awards, the performance period would end upon the change in control; however, the awards would not vest until the earlier to occur of a termination

within 24 months of the change in control or the normal vesting date. Unvested performance awards would not be forfeited if (i) employment is terminated during a potential change in control period by the Corporation for other than

cause or disability or by the executive for good reason and (ii) a 409A Change in Control occurs within twenty-four months following the commencement of the potential change in control period.


Pension Plan Compensation

Pension Plan Compensation includes benefits under the following plans:following:

U. S. Steel Pension Plan

Benefits under the U. S. Steel Pension Plan are payable on behalf of Mr.Messrs. Matthews and Buckiso under each of the termination of employment scenarios. Refer to the “Pension Benefits”"Pension Benefits" section for a description of the U. S. Steel Pension Plan. Benefits under the U. S. Steel Pension Plan may be payable under the Non Tax-Qualified Pension Plan to the extent they are limited by the qualified plan limitations established byunder the Internal Revenue Code.

If an executive is placed on involuntary layoff status as of December 31, 20162017 (Column C), the executive would be eligible to remain on layoff for a period of up to two years. Having satisfied certain age and service requirements, Mr.Messrs. Matthews and Buckiso would each be eligible to commence a Rule-of-70/80 early retirement option on December 31, 20172018 after being on layoff for one year. The present value amounts shown for an involuntary termination not for cause (Column C) reflect enhanced benefits attributable to the additional age and continuous service accrued while on layoff, the lower early-commencement charges, and a temporary $400 monthly pension benefit that is payable until the executive becomes eligible for a public pension.

If an executive becomes inactive on December 31, 20162017 due to a disability (Column E), which is determined to be a

permanent incapacity, the executive would be eligible to commence a Permanent Incapacity early retirement on May 31, 2017,2018, which is five months after the qualifying disability. The present value amounts shown reflect enhanced benefits attributable to the additional age and continuous service accrued during the five-month period, and the lower early-commencement charges, but not the temporary $400 monthly pension benefit that is payable until the executive becomes eligible for a public pension or, if earlier, governmental disability benefits.

If the employment of an executive is terminated due to death (Column F), death benefits become payable to the survivor (typically his or her spouse) or, if there is no spouse, to the executive’sexecutive's estate. The present value amounts shown are equal to the higher of (i) the actuarial equivalent of the executive’sexecutive's pension benefit (excluding the survivor and surviving spouse’sspouse's benefits) that would have been payable if the executive had retired on the date of death, or (ii) the value of the survivor and surviving spouse’sspouse's benefits as defined in the U. S. Steel Pension Plan.


Non Tax-Qualified Pension Plan

Benefits from the Non Tax-Qualified Pension Plan are payable on behalf of Mr.Messrs. Matthews and Buckiso under each of the termination of employment scenarios. Refer to the “2016"2017 Pension Benefits - Non Tax-Qualified Pension Plan”Plan" section for a description of the Non Tax-Qualified

Tax-Qualified Pension Plan. The present value amounts shown for the various termination scenarios vary based upon the total amount payable under the U. S. Steel Pension Plan before the application of the statutory limitations established by the Internal Revenue Code.

Potential Payments Upon Termination or Change in Control

Non-Qualified Deferred Compensation

Non-Qualified Deferred Compensation includes benefits under the following plans:

Supplemental Thrift Program

The conditions for a payment of benefits under the Supplemental Thrift Program include the attainment of five years of continuous service. For Mr.Messrs. Matthews, Rintoul and Buckiso, this condition has been met and therefore, this benefit is payable under all termination scenarios.

Because Messrs. Longhi, Burritt, Bradley and Bruno and Ms. FolsomSoni have not yet attained five

employee insurance coverage to the executive for a period of 36 months or, if earlier, until the executive’s 65thexecutive's 65th birthday.


Supplemental Retirement Benefit

The supplemental retirement benefit represents the increase in retirement benefits to an executive in the event of a termination in connection with a change in control (Column D) and is paid pursuant to the CIC Plan (see “Termination"Termination Scenarios - Change in Control and Termination”Termination", above). For all NEOs, the Supplemental Retirement Benefit is equal to the sum of (i) the Retirement

Account contributions that would have been received

under the U. S. Steel Savings Plan and the Corporation’sCorporation's related non tax-qualified plans if their employment would have continued for an additional 36 months plus earnings, and (ii) the amount they would have received under the U. S. Steel Savings Plan and the related non tax-qualified plans if they were fully vested on December 31st.


Outplacement Services and Excise Tax Gross-Up

We are committed to a compensation program that is internally equitable to motivate our employees to advance the strategy of Stockholder Vote on Executive Compensationthe Corporation and enhance stockholder value. The disclosure below presents the ratio of annual total compensation of our CEO to the annual total compensation of our Median Employee (defined below), excluding our CEO.

PROPOSAL 3: ADVISORY VOTE ON FREQUENCY OF STOCKHOLDER VOTE ON EXECUTIVE COMPENSATION

This year stockholders will be asked to vote on how frequently they would like to cast an advisory vote regardingBecause Mr. Burritt did not serve as our CEO for the entirety of 2017, for purposes of this disclosure, the annual total compensation for the CEO was determined by annualizing the compensation of Mr. Burritt based on his compensation as of October 1, 2017. This amount differs from Mr. Burritt's "Total Compensation" reported in the Corporation’s named executive officers. By votingSummary Compensation Table on page 40 of this proposal, which is also an advisory vote, stockholders may indicate whether they would prefer an advisory vote on named executive officer compensation every year, every two years or every three years.

We calculated each employee's annual total cash compensation to identify our Median Employee. The calculation of annual total cash compensation of each employee was determined by calculating the total cash compensation over the twelve-months ended October 1, 2017 (the "Determination Date"). Pay elements that conducting an advisory vote on executive compensation every year is appropriate for U. S. Steel and its stockholders at this time. While the Corporation’s compensation policies and procedures are developed with long term objectives in mind, the Board believes that stockholder votes every year will permit stockholders to express their views on our compensation

practices on a regular basis and provide us with more direct and immediate feedback.

Although this vote is advisory and not binding on the Board of Directors or the Corporation, the Board will carefully consider the outcome of the vote when making future decisions regarding the frequency of advisory votes on executive compensation. However, the Board may decide that it iswere included in the best interestsannual total cash compensation for each employee are:

Salary, base wages and/or overtime received (as applicable);

annual incentive payment received for performance in fiscal year 2016 (for non-represented employees);

cash incentive payments, based on production (for represented employees only);

Quarterly profit sharing payments (for represented employees only); and
Other cash payments (including payments related to shift differential, holidays and vacations) (for represented employees only).

All of our stockholders.thirteen employees located in the Czech Republic, France, Germany, United Arab Emirates, Canada and Italy, representing less than 5% of our total employee population, were excluded due to administrative challenges related to collecting the necessary data for these employees. We excluded 3, 3, 3, 1, 2 and 1 employees from the Czech Republic, France, Germany, United Arab Emirates, Canada and Italy, respectively. Our total U.S. employee and non-U.S. employee population (including leased employees), during the twelve-month period ended October 1, 2017, was 27,637, which is the number of employees used to determine that the excluded employees represent less than 5% of our total employee population.

We applied a foreign currency exchange rate to all compensation elements paid in currencies other than U.S. dollars.

The Board recommendsWe determined the Median Employee by: (i) calculating the annual total cash compensation described above for each employee; (ii) ranking the annual total cash compensation of all employees except for the CEO, from lowest to highest; and (iii) identifying the employee with the median total cash compensation (who we refer to as the "Median Employee"). Once the Median Employee was determined, that stockholders vote to conduct future advisory votes on executiveemployee's annual total compensation on an ANNUAL basis.was calculated in the same manner as the "Total Compensation" shown for our CEO in the "Summary Compensation Table."

Our Board of Directors upon recommendation of the Compensation & Organization Committee (the “Committee”), has approved an amendment to the    United States Steel Corporation  2016 Omnibus Incentive Compensation Plan (the “2016 Plan” or “Plan”), subject to approval by our stockholders at the Annual Meeting, to increase the number|  2018 Proxy Statement    |57


Table of shares authorized for issuance under the Plan by 6.3 million shares (the “Share Increase Amendment”).Contents

The purpose of the 2016 Plan is to attract, retain and motivate employees and non-employee directors of outstanding ability and to align their interests with those of the Corporation’s stockholders. The availability of an adequate number of shares available for issuance under the 2016 Plan is an important factor in fulfilling these purposes.

The Plan currently authorizes the issuance of 7,200,0000 shares of common stock. The Committee expects that if the stockholders approve the Share Increase Amendment, the number of shares available under the 2016 Plan will be sufficient for approximately two or three years based on current expected equity grant practices. If the proposed Share Increase Amendment is not approved by our stockholders, the 2016 Plan will continue in effect in its present form and we will continue to grant equity awards under the terms of the 2016 Plan until the shares remaining available for issuance are exhausted, which the Committee estimates will occur in 2018 based on current expected equity grant practices. Failure of our stockholders to approve the Share Increase Amendment also will not affect the rights of existing award holders under the 2016 Plan or under any previously granted awards under the 2016 Plan.


Highlights of the 2016 Plan

No repricing of stock options or stock appreciation rights without stockholder approval;
Dividends and dividend equivalents may not be paid with respect to performance awards before the performance goals are achieved and the performance awards are earned;
Minimum vesting period of 12 months, except in the event of death, disability, retirement, termination of employment without cause or a change in control;
Minimum 30% change in control trigger;
Consummation of transaction required for change in control;
“Double trigger” vesting of awards upon a change in control;
No liberal share recycling; and
Recoupment policy of incentive awards.

Audit Committee Report


Background

The 2016 Plan adopted by the Board and approved by the stockholders in 2016 authorizes the issuance of 7,200,000 shares of common stock for equity granted after the date of the 2016 Annual Meeting. The 2016 Plan replaced the Corporation’s 2005 Stock Incentive Plan (the “2005 Plan”), and no new awards may be issued under the 2005 Plan, although outstanding awards under the 2005 Plan granted before the approval of the 2016 Plan remain outstanding according to their terms.

In determining the number of shares of common stock to be requested by the Share Increase Amendment, the Committee considered the needs of the Corporation’s long term incentive program and the potential dilution that awarding the requested shares may have on the existing stockholders. An independent compensation advisor assisted the Committee in determining the appropriate number of shares to be requested. The advisor

examined a number of factors, including the Corporation’s burn rate and an overhang analysis, taking into account equity awards made under the 2016 Plan and awards made under the 2005 Plan.

The burn rate is the total equity awards granted by the Corporation in a fiscal year divided by the weighted average common stock outstanding in the year indicated. In fiscal 2014, 2015 and 2016, the Corporation made equity awards representing a total of 2,808,440 shares, 2,719,532 shares and 2,771,672 shares, respectively. Under the ISS Proxy Advisor Services (“ISS”) burn rate methodology, one full value share is equivalent to two stock options. If the performance awards that were not earned and were forfeited are excluded, then the ISS adjusted three-year average burn rate would be 1.94% as shown in the table below. This is below the applicable ISS 2017 burn rate cap of 2.86%.

(2)Under the ISS burn rate methodology, the “Total Granted/Earned” is equal to the number of options granted plus 1.5 times the number of RSUs granted and performance awards earned.

An additional metric used to measure the cumulative dilutive impact of an equity program is overhang. The calculation of overhang can be described as (A+B) / (A+B+C) where:

A is the number of outstanding stock options and outstanding full value awards;
B is the number of shares available for future grant under the proposed plan; and   
C is the total outstanding shares of common stock.

As of December 31, 2016, the Corporation had 5,693,211 outstanding stock options with a weighted average remaining term of 5.96 years, and a weighted average exercise price of $29.94. As of that date, the Corporation had 1,593,155 outstanding full value awards, and 5,524,364 shares available

for future grant under the 2016 Plan. As of that date, the Corporation had 173,810,176 outstanding shares of Common Stock. This results in an overhang of 7.37%.

Because this proposal does not contemplate the amount or timing of specific equity awards in the future, and because historic rates of awards may not be indicative of future rates of awards, it is not possible to calculate with certainty the number of years of awards that will be available and the amount of subsequent dilution that may ultimately result from such awards. However, the current rationale and practices of the Committee with respect to equity awards is set forth in the “Long-Term Incentive Compensation” section and elsewhere in the Compensation Discussion & Analysis section of this proxy statement.


Summary of the 2016 Omnibus Incentive Compensation Plan

The following is a summary of the main features of the 2016 Plan. This summary is qualified in its entirety by the specific terms of the 2016 Plan, which is incorporated into this proposal by reference

to Exhibit 10.1 of the Corporation’s quarterly report on Form 10-Q for the quarter ending March 31, 2016, which was filed with the U.S. Securities and Exchange Commission on April 27, 2016.


Purpose

The purpose of the Plan is to attract, retain and motivate employees and non-employee directors of outstanding ability

and to align their interests with those of the Corporation’s stockholders.


Eligibility

All employees, non-employee directors and other service providers of the Corporation or any subsidiary or affiliate are eligible to receive various stock and cash-based awards

under the Plan. As of December 31, 2016, the Corporation had approximately 327 employees and eleven non-employee directors eligible to receive awards under the Plan.


Shares Subject to the 2016 Plan

The maximum number of shares of U. S. Steel common stock which may be issued under the 2016 Plan is 7,200,000 shares, subject to proportionate adjustment in the event of stock splits and similar events. If approved by the stockholders, the Share Increase Amendment would increase the maximum number of shares that may be issued under the Plan to 13.5 million shares, subject to proportionate adjustment in the event of stock splits and similar events.

For purposes of measuring the number of shares issued under the Plan, each stock option or appreciation right, will reduce the number of shares available under the Plan by one share, except to the extent the award is settled in cash. All other awards, unless settled in cash, reduce the number of shares available

under the Plan by 1.73 shares for each such share to which the award relates. Shares delivered in payment of the exercise price of an award or to satisfy withholding obligations, or which are repurchased through the use of option proceeds are counted against the number of shares granted, and are not again available for awards under the Plan. All shares covered by an appreciation right that is exercised and settled in shares are also counted against the number of shares granted.

The number of shares to which an award under the 2016 Plan relates is counted against the number of shares available for issuance at the time of grant unless such number of shares cannot be determined at that time, in which case the number of shares actually distributed pursuant to the award is counted against the


   United States Steel Corporation | 2017 Proxy Statement   |   57

Proposal 4: Approval of Amendment of the 2016 Omnibus Incentive Compensation Plan to Increase the Number of Authorized Shares by 6.3 Million Shares

number of available shares at the time of distribution. If, and to the extent, any award granted under the 2016 Plan or the 2005 Plan is forfeited or otherwise terminates without the issuance of shares or if payment is made to the participant in the form of cash, cash equivalents or other property other than shares, any shares that are not issued with respect to such award, to the extent of any such forfeiture or termination or alternative payment, are again available for issuance under the 2016 Plan at the rate for which the award was originally subtracted from the number of shares under the 2005 Plan or 2016 Plan, as applicable.

If the exercise price of an award is paid by a participant by delivery of shares or by withholding shares issuable upon

exercise or if shares are delivered or withheld for the satisfaction of tax withholding obligation, or if shares are repurchased by the Corporation with option proceeds, the number of shares covered by the award equal to the number of shares so delivered, withheld or repurchased are counted against the number of shares granted and are not again available for awards under the 2016 Plan.

Shares distributed pursuant to an award may be, in whole or part, authorized and unissued shares or treasury shares. No awards may be granted under the 2016 Plan after April 26, 2026.


Administration

Except in the case of awards to non-employee directors, the 2016 Plan is administered by a committee of the Board consisting of at least three members of the Board who qualify as an “outside director” as defined in Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), a “non-employee director” as defined in Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and an “independent” director under the rules of the New York Stock Exchange. The Committee administers awards made to employees of the Corporation. In the case of awards to non-employee directors, the 2016 Plan is administered by the Board.

The Committee has full and final authority to interpret and administer the Plan and to determine the persons who receive awards, type or types of awards, the number of shares covered by each award and to what extent and what circumstances an

award may be settled in cash, shares, other awards or property or accelerated, vested, canceled, forfeited, exchanged or surrendered. All decisions made by the Committee pursuant to the terms of the Plan are final, conclusive and binding on all persons, including the Corporation, its subsidiaries and participants.

The Committee may delegate to one or more officers, managers and/or agents of the Corporation the authority to perform administrative and other functions under the Plan. The Committee may also delegate to one or more officers of the Corporation the authority to grant awards to participants who are not directors or executive officers (as defined under Section 16 of the Exchange Act), subject to limitations established by the Committee and applicable law.


Types of Awards

The types of awards that may be granted include but are not limited to: (1) stock options, (2) restricted stock, (3) restricted stock units, (4) performance awards and (5) other stock-based awards, including appreciation rights. Each of these types of awards is described below.

Stock Options. The Plan provides for the grant of nonstatutory stock options. The option price for each stock option may not be less than 100% of the fair market value of the Corporation’s common stock on the date of grant. Fair market value, for purposes of the Plan, is generally the average of the publicly reported high and low sale prices per share of the Corporation’s common stock on the date of grant.

A stock option may be subject to such restrictions and other terms and conditions, if any, as shall be determined, in its discretion, by the Committee. All options have a term of ten years from the date of grant. The option price for each stock option will be payable upon exercise in cash, or by such other method authorized by the Committee, including by delivery or withholding of U. S. Steel common stock issued pursuant to such option price for the shares being purchased.

Restricted Stock. Shares of the Corporation’s common stock may be issued subject to such restrictions and conditions as the Committee may specify, including but not limited to service requirements and performance goals (see “Performance Awards” below). From the date a restricted stock award is

effective, the awardee will be a stockholder with respect to the restricted stock award and will have all the rights of a stockholder with respect to such shares, including the right to vote the shares and to receive all dividends and other distributions paid with respect to the shares, subject only to the restrictions imposed by the Committee.

Restricted Stock Units. Restricted stock units provide for the issuance of the Corporation’s common stock subject to such restrictions and conditions, including but not limited to service requirements and performance goals (see “Performance Awards” below), as the Committee may impose. The awardee will not be a stockholder with respect to the restricted stock units and will not have the rights of a stockholder with respect to such units until the shares are issued upon the vesting of the award. The Committee may determine to pay dividend equivalents relative to the shares that ultimately vest.

Performance Awards. Performance awards are based on the achievement during a specified performance period of one or more performance goals established by the Committee at the time of the award. These awards may be designated as performance shares or performance cash awards. Performance shares are denominated in shares of common stock and may be paid in shares or cash. Performance cash awards are denominated in dollars, have an initial value that is established by the Committee at the time of grant, and may be paid in cash or shares.

Proposal 4: Approval of Amendment of the 2016 Omnibus Incentive Compensation Plan to Increase the Number of Authorized Shares by 6.3 Million Shares

The Committee will set forth in writing the performance goals applicable to the award, the performance period during which the achievement of the performance goals shall be measured, the amount that may be earned by the participant based on the achievement of the performance goals and such other terms and conditions applicable to the award as the Committee may, in its discretion, determine. The Committee may retain the discretion to reduce (but not to increase) the amount of a performance award which will be earned based on the achievement of performance goals. Dividends and dividend equivalents may accrue, but may not be paid with respect to performance awards before the performance goals are achieved and the performance awards are earned.

Performance goals may be based on one or more of the following objective performance measures and expressed in either, or a combination of, absolute or relative values or rates of change and on a gross or net basis: safety performance, stock price, capital expenditures, earnings per share, earnings per share growth, return on capital employed, return on invested capital, return on capital, costs, net income, net income growth, operating margin, revenues, revenue growth, revenue from operations, net sales, expenses, income from operations as a percent of capital employed, income from operations, income from operations per ton shipped, tons shipped, cash flow, market share, return on equity, return on assets, earnings (including EBITDA and EBIT), operating cash flow, operating cash flow as a percent of capital employed, economic value added, gross margin, total stockholder return, stockholder equity, debt, debt to stockholder equity, debt to earnings (including EBITDA and EBIT), interest expense and/ or other fixed charges, earnings (including EBITDA and EBIT) to interest expense and/or other fixed charges, environmental emissions improvement, workforce diversity, number of accounts, workers’ compensation claims, budgeted amounts, cost per hire, turnover rate, and/or training costs and expenses.

Performance goals based on such performance measures may be based either on the performance of the participant, the Corporation, a subsidiary or subsidiaries, affiliate, any branch, department, business unit or other portion thereof under such measure for the performance period and/or upon a comparison of such performance with the performance of a peer group of corporations, prior performance periods or other measure selected or defined by the Committee at the time of making a performance award. The Committee may in its discretion also determine to use other objective performance measures as performance goals; however, the compensation awarded in connection with performance measures other than those identified above will not satisfy the exemption for “performance based compensation” under Section 162(m) of the Code. (See “Federal Income Tax Consequences –Other Tax Matters” below.)

The Committee determines and certifies in writing whether the applicable performance goal or goals were achieved, or the level of such achievement, and the amount, if any, earned by the participant based upon such performance.

Other Stock-Based Awards. The Committee may grant to eligible employees, in lieu of salary or cash bonus, such other awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, shares of the Corporation’s common stock, including, without limitation, purchase rights, appreciation rights, shares of common stock awarded without restrictions or conditions, subject to the limitations of the Plan, convertible securities, exchangeable securities or other rights convertible or exchangeable into shares of common stock, as the Committee in its discretion may determine. The Committee will determine the terms and conditions of other stock-based awards. Appreciation rights may not be granted at a price less than the fair market value of the underlying shares on the date of grant.


Award Limits

In order to permit awards to qualify as “performance-based compensation” under Section 162(m) of the Code, awards may not be granted in any calendar year to any participant in excess of the following aggregate limits, subject to the adjustments described below:

For stock options and appreciation rights, 1,000,000 shares (this limit applies separately to each type of award).
For restricted stock and restricted stock units, 1,000,000 shares (the limit applies separately to each award).
For performance shares, 1,000,000 shares (or the cash value thereof).
For performance cash awards, $20,000,000 in value.

The aggregate grant date fair value of awards that may be granted to any individual non-employee director in any single calendar year shall not exceed $500,000. This limit does not apply to any awards made at the election of a non-employee director in lieu of all or a portion of any annual committee cash retainers or other similar cash based payments.

In the event a dividend or other distribution is declared on the Corporation’s stock, or if the outstanding stock is changed into or exchangeable for a different number or kind of stock or securities of the Corporation or another corporation, the award limitations above, and any shares remaining in the Plan that are not subject to outstanding awards, shall be adjusted in an equitable manner as determined by the Committee.


Vesting

All awards granted under the Plan will provide for vesting based on employment or service for a period of at least twelve (12) months from the date on which such award is granted and there is no acceleration of vesting to be more rapid than vesting after twelve (12) months, except in connection with death,

disability, retirement, involuntary termination of employment or service without cause or a change in control. However, up to five percent of the aggregate number of shares authorized for issuance under the 2016 Plan may be issued pursuant to awards that do not satisfy these vesting restrictions.

Proposal 4: Approval of Amendment of the 2016 Omnibus Incentive Compensation Plan to Increase the Number of Authorized Shares by 6.3 Million Shares

Repricing and Reload Options Prohibited

The Committee may not, without stockholder approval (1) amend or modify the terms of any outstanding option or appreciation right to reduce the exercise price or (2) cancel, exchange or permit or accept the surrender of any outstanding option or appreciation right in exchange for an option or appreciation right

with an exercise price that is less than the exercise price of the original option or appreciation right, or an award, cash or other securities for purposes of repricing the option or appreciation right. No option may be granted to any individual on account of the use of shares to exercise a prior option.


Change in Control

Unless otherwise determined by the Committee, if a change in control occurs and within two (2) years thereafter a participant’s employment is terminated either (i) involuntarily for any reason other than cause or, (ii) in the case of a member of executive management, as determined by the Committee, voluntarily by the participant for good reason, then (1) all outstanding stock options, and other awards under which the participant may have rights the exercise of which is restricted or limited, shall become fully exercisable and remain exercisable until the expiration date of such award and (2) all restrictions or limitations, including

risks of forfeiture and deferrals, on awards subject to restrictions or limitations under the Plan shall lapse. All performance goals applicable to performance awards shall be measured over the shortened performance period ending on the date of the change in control. Unless otherwise determined by the Committee at the time of grant, scheduled vesting dates for performance-based awards are not affected by a change in control, and all awards remain payable on the dates provided in the underlying award agreements and the Plan.


Miscellaneous

The Board may amend, alter, suspend, discontinue or terminate the Plan at any time without stockholder approval except to the extent that stockholder approval is required by law or stock exchange rules or if the amendment, alteration or other change materially increases the benefits accruing to participants, increases the number of shares available under the Plan or modifies the requirements for participation under the Plan or if the Board determines that stockholder approval is advisable.

Without the consent of the participant, no amendment, suspension or termination of the Plan or any award may materially and adversely affect the rights of such participant under any previously granted award.

The Committee may determine that an award shall be forfeited and/or any value received from the award is subject to recovery under any law, government regulation, stock exchange listing requirement or any policy adopted by the Corporation.


Plan Benefits

The actual amount of awards to be received by or allocated to participants or groups under the Plan is not determinable in advance because the selection of participants who receive awards under the Plan, and the size and type of awards, are

generally determined by the Committee in its discretion. The following table reflects the award of stock options under the 2016 Plan as of December 31, 2016.

Federal Income Tax Consequences

The following is a brief summary of the federal income tax consequences of the grant and exercise of awards under present law. It should not be taken as tax advice by Plan participants, who are urged to consult their individual tax advisors. Except as

described in “Other Tax Matters” below, the Corporation generally will be entitled to a corresponding deduction in the same amount of compensation recognized as taxable income by the participant.


60   |   United States Steel Corporation | 2017 Proxy Statement   

Proposal 4: Approval of Amendment of the 2016 Omnibus Incentive Compensation Plan to Increase the Number of Authorized Shares by 6.3 Million Shares

Nonqualified Stock Options. A participant who is awarded a nonqualified stock option will not recognize any taxable income for federal income tax purposes upon receipt of the award. Upon exercise of the option, the amount by which the fair market value of the shares received, determined as of the date of exercise, exceeds the option price generally will be taxable to the participant as ordinary income. If the option price of a nonstatutory stock option is paid in whole or in part with shares of the Corporation’s common stock, no income, gain or loss will be recognized by the participant on the receipt of shares delivered in payment of the option price. The fair market value of the remainder of the shares received upon exercise of the option, less the amount of cash, if any, paid upon exercise generally will be taxable as ordinary income.

Restricted Stock. A participant who is awarded restricted stock will not recognize any taxable income for federal income tax purposes in the year of the award, provided the shares are subject to restrictions on transfer and a substantial risk of forfeiture. However, a participant may elect under Section 83(b) of the Code to recognize ordinary income on the date of grant equal to the difference (if any) between the then-fair market value of the shares determined without regard to the restrictions and the amount, if any, paid for the shares. If the participant does not make a Section 83(b) election, in the year in which the shares first become transferable or are no longer subject to a substantial risk of forfeiture, the participant will recognize ordinary income equal to the difference, if any, between the then-fair market value of the shares and the amount, if any, paid for the shares.

Restricted Stock Units and Performance Awards. A participant who is awarded restricted stock units, performance shares or performance cash awards will not recognize any taxable income for federal income tax purposes upon receipt of the award. Any shares of common stock or cash received pursuant to the award generally will be taxable as ordinary income in the year in which the participant receives such shares of common stock or cash.

Appreciation Rights. A participant will not recognize any taxable income for federal income tax purposes upon receipt of appreciation rights. The value of any common stock or cash received in payment of appreciation rights generally will be taxed

as ordinary income in the year in which the participant receives the common stock or cash.

Other Tax Matters. The lapse of vesting or other restrictions on a stock option or appreciation right, restricted stock and restricted stock units, or the deemed achievement or fulfillment of performance goals for awards, in connection with the occurrence of a change in control, in certain circumstances, may result in (i) a 20% federal excise tax (in addition to federal income tax) to the participant and (ii) the unavailability of a compensation deduction which would otherwise be allowable to the Corporation as explained above.

Except for stock options and appreciation rights, and certain restricted stock awards, restricted stock unit awards and performance awards that meet the requirements of the Plan and are based on the performance measures described therein, the Corporation may not be eligible for a compensation deduction which would otherwise be allowable for compensation paid to any employee if, as of the close of the tax year, the employee is the chief executive officer of the Corporation or is among the three other highest compensated officers for that tax year for whom compensation is required to be reported to stockholders under the Securities Exchange Act, as amended, to the extent the total compensation paid to such employee in such year exceeds $1,000,000.

Additional Information. Stock options and appreciation rights, performance awards, restricted stock and restricted stock unit awards that are based on performance measures set forth in the Plan and otherwise meet the requirements of the Plan may qualify as “performance-based compensation” that is exempt from the $1,000,000 annual federal income tax deduction limit imposed by Section 162(m) of the Code on compensation paid to each of the Corporation’s chief executive officer and three other most highly compensated executive officers in each fiscal year. Because of ambiguities and uncertainties as to the application and interpretation of Section 162(m) of the Code and the regulations issued thereunder, no assurance can be given, notwithstanding the Corporation’s efforts, that compensation intended by the Corporation to satisfy the requirements for deductibility under Section 162(m) of the Code will in fact do so.


Board Recommendation

The Board recommends a vote FOR the approval of the Share Increase Amendment to the 2016 Plan.

   United States Steel Corporation | 2017 Proxy Statement   |   61

Proposal 5: Approval of Amended and Restated Certificate of Incorporation

PROPOSAL 5: APPROVAL OF AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

At the 2014 Annual Meeting of Stockholders, the Corporation’s stockholders approved the elimination of the Board’s classified structure over a three year period. The progressive declassification process is detailed in the Corporation’s Restated Certificate of Incorporation, as amended. The process of declassifying the Board will be complete as of the 2017 Annual Meeting of Stockholders, at which time all directors will be elected for an annual term.

Our Board of Directors has unanimously approved and declared the advisability of an amendment and restatement to the Restated Certificate of Incorporation (the “Amended Certificate”) to (i) eliminate all references to the classified structure of the board, and (ii) incorporate all amendments into a singular document for administrative ease. The Board is submitting the proposed Amended Certificate to the stockholders of the Corporation for their approval at the 2017 Annual Meeting of Stockholders.

The complete text of the proposed Amended and Restated Certificate of Incorporation is set forth in Appendix B.

If the Amended Certificate is approved by the affirmative vote of stockholders holding a majority of the outstanding shares of the Corporation, the Amended Certificate will become effective upon the filing of the Amended and Restated Certificate

of Incorporation with the Secretary of State of the State of Delaware. The Corporation intends to file the Amended Certificate promptly following stockholder approval.

The Board recommends the Amended Certificate because, as of the 2017 Annual Meeting of Stockholders, all of Corporation’s directors will be subject to election or re-election on an annual basis as a result of the declassification of the Board, which was approved by the Corporation’s stockholders at the 2014 annual meeting of stockholders. The Amended Certificate is intended to eliminate all references to the classified board structure, as it will no longer be applicable to the Corporation following the 2017 Annual Meeting of Stockholders.

If the Amended Certificate is not approved by the affirmative vote of a majority of our outstanding shares at the 2017 Annual Meeting, the Restated Certificate of Incorporation will not be amended and restated, and the current Restated Certificate of Incorporation will remain in effect.

Accordingly, our Board declares the advisability of the Amended Certificate to eliminate references to a classified board structure, directs that the Amended Certificate be considered at the Corporation’s 2017 Annual Meeting of Stockholders, and unanimously recommends that stockholders voteFOR approval of this proposal.


The Board recommends a vote FOR approval of the amended and restated Certificate of Incorporation.

AUDIT COMMITTEE REPORTAudit Committee Report

Our committeeThe Audit Committee has reviewed and discussed U. S. Steel’sSteel's audited financial statements for the year ended December 31, 20162017 with U. S. Steel’sSteel's management. We have discussed with the independent registered public accounting firm, PricewaterhouseCoopers LLP (PwC), the matters required to be discussed by Statements on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380),1301 "Communication with Audit Committees," as adopted by the Public Company Accounting Oversight Board in Rule 3200T.Board.

PROPOSAL 3: RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Proposal 6: Ratification of the Appointment of Pricewaterhousecoopers LLP as Independent Registered Public Accounting Firm

PROPOSAL 6: RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Pursuant to the authority provided by its charter, the Audit Committee has appointed PricewaterhouseCoopers LLP (PwC) as the independent registered public accounting firm for U. S. Steel for the current fiscal year. Although action by the stockholders in this matter is not required by law or the Corporation’sCorporation's by-laws, the Audit Committee believes that it is appropriate to seek stockholder ratification of this appointment in light of the important role played by the independent registered public accounting firm in maintaining the integrity of the Corporation’sCorporation's financial controls and reporting. If the appointment of PwC is not ratified by the stockholders, the Audit Committee will reconsider its appointment and review its future selection of an independent registered public accounting firm in light of that result. However, the Audit Committee may decide to maintain its appointment of PwC. Even if the appointment is ratified, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of the Corporation and our stockholders. PwC has served as the independent auditor (now referred to as the independent registered public accounting firm) of U. S. Steel for many years. We believe that PwC&rsquo;sPwC's knowledge of U. S. Steel&rsquo;sSteel's business and its organization gained through this period of service is quite valuable. Partners and employees of PwC assigned to the U. S. Steel engagement are periodically rotated, thus giving U. S. Steel the benefit of new thinking and approaches in the audit area.

The Audit Committee annually requests PwC to prepare a self-assessment utilizing the Center for Audit Quality, External Auditor Assessment Tool. This best practice assists the Audit Committee in its oversight role and annual evaluation of PwC to assess the quality of the audit and to recommend the retention of PwC. Based on this assessment, we believe the quality of PwC’sPwC's services, communication and interaction with the Audit Committee is of a high standard. We expect representatives of PwC to be present at the annual meeting with an opportunity to make a statement if they desire to do so and to be available to respond to appropriate questions.

For fiscal year 2016,2017, PwC performed professional services for U. S. Steel in connection with audits of the financial statements of U. S. Steel, and of U. S. Steel’sSteel's internal control over financial reporting as of December 31, 2016,2017, and audits of certain subsidiaries and certain pension and other employee benefit plans. PwC has also reviewed quarterly reports and other filings with the Securities and Exchange Commission and other agencies and provided advice and consultation on tax matters.

The Board recommends a vote FOR the ratification of the appointment of PwC as our independent registered public accounting firm.

USE OF NON-GAAP FINANCIAL MEASURES

USE OF NON-GAAP FINANCIAL MEASURES

This proxy statement contains the non-GAAP financial measure adjustedmeasures earnings (loss) before interest, income taxes, depreciation, depletion and amortization “EBITDA”.

"EBITDA", adjusted EBITDA and net debt.

We believe that adjusted EBITDA, considered along with the net earnings (loss), is a relevant indicator of trends relating to cash generating activityour operating performance and provides management and investors with additional information for comparison of our operating results to the operating results of other companies.

Net debt is a non-GAAP measure calculated as total debt less cash and cash equivalents. We believe net debt is a useful measure in calculating enterprise value. Both EBITDA and net debt are used by analysts to refine and improve the accuracy of their financial models that utilize enterprise value.

Adjusted EBITDA is a non-GAAP measure that excludes the effects of gains (losses) associated with our retained interest in U. S. Steel Canada Inc., gains (losses) on the sale of ownership interests in equity investees, restructuring charges, impairment charges and losses associated with U. S. Steel Canada, Inc.

significant temporary idling charges.

We present adjusted EBITDA to enhance the understanding of our ongoing operating performance and established trends affecting our core operations, particularly cash generating activity, by excluding the effects of gains (losses) associated with our retained interest in U. S. Steel Canada Inc., gains (losses) on the sale of ownership interests in equity investees, restructuring charges, impairment charges, losses on debt extinguishment, certain postemployment actuarial adjustments,and significant temporary idling charges, for deferred tax asset valuation allowances and losses associated with non-core operations that can obscure underlying trends. U. S. Steel’sSteel's management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted shareEBITDA as an alternative measure of operating performance and not an alternative measure of the Company's liquidity. U. S. Steel's management considers adjusted EBITDA useful to investors by facilitating a comparison of our operating performance to the operating performance of our competitors, many of which use adjusted EBITDA as an alternative measure of operating performance.competitors. Additionally, the presentation of adjusted EBITDA provides insight into management’smanagement's view and assessment of the Company’sCompany's ongoing operating performance, because management does not consider the adjusting items when evaluating the Company’sCompany's financial performance. Adjusted EBITDA should not be considered a substitute for net earnings (loss), or other financial measures as computed in accordance with U.S. GAAP and areis not necessarily comparable to similarly titled measures used by other companies.

Section 1.Designation and Amount.

The shares of this series shall be designated as “Series A Junior Preferred Stock” and the number of shares constituting such series shall be 2,000,000.

Section 2.Dividends and Distributions.

(a)Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Series A Junior Preferred Stock with respect to dividends, the holders of shares of Series A Junior  Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the first day of March, June, September and December in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Junior Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $5.00 or (b) subject to the provision for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares, of Common Stock (by reclassification or otherwise), to be or being declared on the Common Stock, par value $1.00 per share, of the Corporation (the “Common Stock”) with respect to the same dividend period. If the Quarterly Dividend Payment Date is a Saturday, Sunday or legal holiday then such Quarterly Dividend Payment Date shall be the first immediately preceding calendar day which is not a Saturday, Sunday or legal holiday. In the event the Corporation shall at any time after December 31, 2001 (the “Rights Declaration Date”) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series A Junior Preferred Stock were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.  
(b)The Corporation shall declare a dividend or distribution on the Series A Junior Preferred Stock as provided in paragraph (a) above immediately prior to the time it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall be declared on the Common Stock with respect to a particular dividend period, a dividend of $5.00 per share on the Series A Junior Preferred Stock shall nevertheless be payable on such Quarterly Dividend Payment Date with respect to such quarterly period.  
(c)Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Junior Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A  Junior Preferred Stock entitled, to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Junior Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. Dividends in arrears may be declared and paid at any time, without reference to any Quarterly Dividend Payment Date, to holders of record on such date, not exceeding 45 days preceding the payment date thereof, as may be fixed by the Board of Directors.  
(d)Except as hereinafter provided, no dividends shall be declared or paid or set apart for payment on the shares of Series A Junior Preferred Stock for any period if the Corporation shall be in default in the payment of any dividends (including cumulative dividends, if applicable) on any shares of Preferred Stock ranking, as to dividends, prior to the Series A Junior Preferred Stock, unless the same shall be contemporaneously declared and paid.  
(e)Dividends payable on the Series A Junior Preferred Stock for the initial dividend period and, for any period less than a full quarterly period, shall be computed on the basis of a 360-day year of 30-day months.

(b)Except as otherwise provided herein or by law, the holders of shares of Series A Junior Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation.  
(c)If, on the date used to determine stockholders of record for any meeting of stockholders for the election of directors, a default in preference dividends on the Preferred Stock shall exist, the number of directors constituting the Board of Directors of the Corporation shall be increased by two, and the holders of the Preferred Stock of all series (whether or not the holders of such series of Preferred Stock would be entitled to vote for the election of directors if such default in preference dividends did not exist), shall have the right at such meeting, voting together as a single class without regard to series, to the exclusion of the holders of Common Stock, to elect two directors of the Corporation to fill such newly created directorships. Each director elected by the holders of shares of Preferred Stock (herein called a “Preferred Director”), shall continue to serve as such director for the full term for which he shall have been elected, notwithstanding that prior to the end of such term a default in preference dividends shall cease to exist. Any Preferred Director may be removed by, and shall not be removed except by, the vote of the holders of record of the outstanding shares of Preferred Stock, voting together as a single class without regard to series, at a meeting of the stockholders, or of the holders of shares of Preferred Stock, called for the purpose. So long as a default in any preference dividends on the Preferred Stock shall exist (i) any vacancy in the office of a Preferred Director may be filled except as provided in the following clause (ii) by an instrument in writing signed by the remaining Preferred Director and filed with the Corporation and (iii) in the case of the removal of any Preferred Director, the vacancy may be filled by the vote of the holders of the outstanding shares of Preferred Stock, voting together as a single class without regard to series, at the same meeting at which such removal shall be voted. Each director appointed as aforesaid by the remaining Preferred Director shall be deemed, for all purposes hereof, to be a Preferred Director. Whenever the term of office of the Preferred Directors shall end and no default in preference dividends shall exist, the number of directors constituting the Board of Directors of the Corporation shall be reduced by two. For the purposes of this paragraph (c), a “default in preference dividends” on the Preferred Stock shall be deemed to have occurred whenever the amount of accrued and unpaid dividends upon any series of the Preferred Stock shall be equivalent to six full quarterly dividends or more, and, having so occurred, such default shall be deemed to exist thereafter until, but only until all accrued dividends on all shares of Preferred Stock of each and every series then outstanding shall have been paid through the last Quarterly Dividend Payment Date.  

Section 4.Certain Restrictions.

(a)Whenever quarterly dividends or other dividends or distributions payable on the Series A Junior Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Junior Preferred Stock outstanding shall have been paid in full, the Corporation shall not:
(i)declare or pay dividends on, or make any other distributions on (other than a dividend in Common Stock or in any other stock of the Corporation ranking junior to the Series A Junior Preferred Stock as to dividends and upon liquidation, dissolution or winding up and other than as provided in subparagraph (ii) of this section), or redeem or purchase or otherwise acquire for consideration (except by conversion into or exchange for stock of the Corporation ranking junior to the Series A Junior Preferred Stock as to dividends and upon dissolution, liquidation or winding up), any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Preferred Stock;
(ii)declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Preferred Stock, except dividends paid ratably on the Series A Junior Preferred Stock and all stock ranking on a parity with the Series A Junior Preferred Stock as to dividends on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;
(iii)redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the Corporation ranking junior (as to dividends and upon dissolution, liquidation or winding up) to the Series A  Junior Preferred Stock;  

B-5   |   United States Steel Corporation | 2017 Proxy Statement   
(iv)purchase or otherwise acquire for consideration any shares of Series A Junior Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.  

(b)The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (a) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.  

Section 5.Reacquired Shares.

Any shares of Series A Junior Preferred Stock purchased or otherwise acquired by the Corporation, in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

Section 6.Liquidation, Dissolution or Winding Up.

(a)In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the Series A Junior Preferred Stock shall be entitled to receive the greater of (a) $100 per share, plus accrued dividends to the date of distribution, whether or not earned or declared, or (b) an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 100 times the aggregate amount to be distributed per share to holders of Common Stock (the “Series A Liquidation Preference”). In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series A Junior Preferred Stock were entitled immediately prior to such event pursuant to clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.
(b)In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of preferred stock, if any, which rank on a parity with the Series A Junior Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences.  

Section 7.Consolidation, Merger, etc.

In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Junior Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Junior Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 8.Optional Redemption.

(a)The Corporation shall have the option to redeem the whole or any part of the Series A Junior Preferred Stock at any time on at least 30 days notice in accordance with the provisions of paragraph (b) of this Section 8 at a redemption price equal to, subject to the provision for adjustment hereinafter set forth, 100 times the “current per share market price” of the Common Stock on the date of the mailing of the notice of redemption, together with unpaid accumulated dividends to the date of such redemption. In the event the Corporation shall at any time after December 31, 2001 (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series A Junior Preferred Stock were otherwise entitled immediately prior to such event under the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. The “current per share market price” on any date shall be deemed to  

   United States Steel Corporation | 2017 Proxy Statement   |   B-6
be the average of the closing price per share of such Common Stock for the 10 consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Common Stock is not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if the Common Stock is not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted the average of the high bid and low asked prices in the over-the-counter market, as reported by the National Association of Securities Dealers, Inc. Automated Quotations System (“NASDAQ”) or such other system then in use or, if on any such date the Common Stock is not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Corporation. If on such date no such market maker is making a market in the Common Stock, the fair value of the Common Stock on such date as determined in good faith by the Board of Directors of the Corporation shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the Common Stock is listed or admitted to trading is open for the transaction of business or, if the Common Stock is not listed or admitted to trading on any national securities exchange, a Monday, Tuesday, Wednesday, Thursday or Friday on which banking institutions in the State of New York are not authorized or obligated by law or executive order to close.
(b)Whenever shares of Series A Junior Preferred Stock are to be redeemed, the Corporation shall mail a notice (“Notice of Redemption”) by first-class mail, postage prepaid, to each holder of record of shares of Series A Junior Preferred Stock to be redeemed and to the transfer agent for the Series A Junior Preferred Stock. The Notice of Redemption shall be addressed to the holder at the address of the holder appearing on the stock transfer books of the Corporation maintained by the transfer agent for the Series A Junior Preferred Stock. The Notice of Redemption shall include a statement of (i) the redemption date, (ii) the redemption price, (iii) the number of shares of Series A Junior Preferred Stock to be redeemed, (iv) the place or places where shares of the Series A Junior Preferred Stock are to be surrendered for payment of the redemption price, (v) that the dividends on the shares to be redeemed will cease to accrue on such redemption date, and (vi) the provision under which redemption is made. No defect in the Notice of Redemption or in the mailing thereof shall affect the validity of the redemption proceedings, except as required by law. From the date on which a Notice of Redemption shall have been given as aforesaid and the Corporation shall have deposited with the transfer agent for the Series A Junior Preferred Stock a sum sufficient to redeem the shares of Series A Junior Preferred Stock as to which Notice of Redemption has been given, with irrevocable instructions and authority to pay the redemption price to the holders thereof, or if no such deposit is made, then upon such date fixed for redemption (unless the Corporation shall default in making payment of the redemption price), all rights of the holders thereof as stockholders of the Corporation by reason of the ownership of such shares (except their right to receive the redemption price thereof, but without interest), shall terminate, including, but not limited to, their right to receive dividends, and such shares shall no longer be deemed outstanding. The Corporation shall be entitled to receive, from time to time, from the transfer agent for Series A Junior Preferred Stock the interest, if any, on such monies deposited with it and, the holders of any shares so redeemed shall have no claim to any such interest. In case the holder of any shares so called for redemption shall not claim the redemption price for his shares within one year after the date of redemption, the transfer agent for the Series A Junior Preferred Stock shall, upon demand, pay over to the Corporation such amount remaining on deposit and the transfer agent for the Series A Junior Preferred Stock shall thereupon be relieved of all responsibility to the holders of such shares and such holder of the shares of the Series A Junior Preferred Stock so called for redemption shall look only to the Corporation for the payment thereof.
(c)In the event that fewer than all the outstanding shares of the Series A Junior Preferred Stock are to be redeemed, the number of shares to be redeemed shall be determined by the Board of Directors and the shares to be redeemed shall be determined by lot or pro rata as may be determined by the Board of Directors or by any other method as may be determined by the Board of Directors in its sole discretion to be equitable.
(d)If the Corporation shall be in default in the payment of any dividends (including cumulative dividends, if applicable) on any shares of Preferred Stock ranking, as to dividends, prior to the Series A Junior Preferred Stock, then no shares of the Series A Junior Preferred Stock shall be redeemed and the Corporation shall not purchase or otherwise acquire any shares of the Series A Junior Preferred Stock.  

Section 9.Ranking.

(a)The Series A Junior Preferred Stock shall rank junior to all other series of the Corporation’s Preferred Stock as to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up, unless the terms of any such series shall provide otherwise.
(b)For purposes hereof, any stock of any class or classes of the Corporation shall be deemed to rank:  

B-7   |   United States Steel Corporation | 2017 Proxy Statement   
(i)prior to the shares of the Series A Junior Preferred Stock, either as to dividends or upon liquidation, dissolution or winding up, if the holders of such class or classes shall be entitled to the receipt of dividends or of amounts distributable upon dissolution, liquidation or winding up of the Corporation, whether voluntary or involuntary, as the case may be, in preference or priority to the holders of shares of the Series A Junior Preferred Stock. Each holder of any share of the Series A Junior Preferred Stock, by his acceptance thereof, expressly covenants and agrees that the rights of the holders of any shares of any other series of Preferred Stock of the Corporation to receive dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, shall be and hereby are expressly prior to his rights unless in the case of any particular series of Preferred Stock the certificate or other instrument creating or evidencing the same expressly provides that the rights of the holders of such series shall not be prior to the shares of the Series A Junior Preferred Stock; and
(ii)on a parity with shares of the Series A Junior Preferred Stock, either as to dividends or upon liquidation, whether or not the dividend rates, dividend payment dates or redemption or liquidation prices per share or sinking fund provisions, if any, be different from those of the Series A Junior Preferred Stock, if the holders of such stock shall be entitled to the receipt of dividends or of amounts distributable upon dissolution, liquidation or winding up of the Corporation, whether voluntary or involuntary, as the case may be, in proportion to their respective dividend rates or liquidation prices, without preference or priority, one over the other, as between the holders of such stock and the holders of shares of the Series A Junior Preferred Stock; and junior to shares of the Series A Junior Preferred Stock, either as to dividends or upon liquidation, if such class or classes shall be Common Stock or if the holders of shares of the Series A Junior Preferred Stock shall be entitled to receipt of dividends or of amounts distributable upon dissolution, liquidation or winding up of the Corporation, whether voluntary or involuntary, as the case may be, in preference or priority to the holders of shares of such class or classes.

Section 10.Amendment.

Except as otherwise set forth in this Certificate of Incorporation, Preferences and Rights with respect to the Series A Junior Preferred Stock, holders of Series A Junior Preferred Stock shall not have any special powers and their consent shall not be required for taking any corporate action, provided, however, that:

(1)Unless the vote or consent of the holders of a greater number of shares shall then be required by law, the consent of the holders of at least 66- 2/3% of all of the shares of the Series A Junior Preferred Stock at the time outstanding, given in person or by proxy, either in writing or by a vote at a meeting called for the purpose at which the holders of shares of the Series A Junior Preferred Stock shall vote together as a separate class, shall be necessary for authorizing, effecting or validating the amendment, alteration or repeal of any of the provisions of the Certificate of Incorporation or of any certificate amendatory thereof or supplemental thereto (including any Certificate of Designation, Preferences and Rights or any similar document relating to any series of Preferred Stock) so as to affect adversely the powers, preferences, or rights, of this Series A Junior Preferred Stock. The increase of the authorized amount of the Preferred Stock, or the creation, authorization or issuance of any shares of any other class of stock of the Corporation ranking prior to or on a parity with the shares of the Series A Junior Preferred Stock as to dividends or upon liquidation, or the reclassification of any authorized or outstanding stock of the Corporation into any such prior or parity shares, or the creation, authorization or issuance of any obligation or security convertible into or evidencing the right to purchase any such prior or parity shares shall not be deemed to affect adversely the powers, preferences or rights of the Series A Junior Preferred Stock.

Section 11.Fractional Shares.

 Series A Junior Preferred Stock may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Preferred Stock.
