In 2018 we launched our Best of ContentsBoth strategy to become the best steel company by leveraging the advantages of integrated steelmaking — iron ore and product innovation – with the advantages of mini mills – process innovation and cost efficiency. Our strategy is to create long-term stockholder value by pursuing a business model that is resilient to market volatility and is profitable through the business cycle.

DEAR FELLOW U. S. STEEL STOCKHOLDER


Thank youCompetitive assets with distinct advantages deploying fit for your investment in U. S. Steelpurpose processes


Long-term cash flow generation through higher earnings and the trust you have placed in the Board of Directors, as stewards of the Corporation. I am honored to be penning my first update to you as U. S. Steel President & CEO and proud to be leading a companylower sustaining capex

Variable cost structure 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 positive trends. This focus allowed us to meet or exceed our primary goals for improved EBITDA,drives through cycle cash generation and liquidity by year-end. This represents a good start, but we know we still have work to do to make this kind of stability our new normal, rather than an exception.

After the first quarter, we quickly refocused and rallied around four business drivers we identified as key to achieving operational excellence and advancing our ongoing strategic transformation: safety, quality, delivery, and cost. We knew improving these four pillars would help us:

create value for all U. S. Steel 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 quickly decided to accelerate plans around the strategic revitalization of assets in our North American Flat-Rolled operations. Guided by our Carnegie Way methodology, we developed performance measures around EBITDA return, quality and reliability 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 health 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 our 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 judiciously and promptly responded to environmental issues. As we did with safety, we continue to take 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 around 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 further 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 commitment to continuous improvement, we are also looking at ways to improve our workplace culture companywide. At U. S. Steel, we are committed to getting 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, we will remain focused on all the things we can control that make us a better company, beginning with safety, quality, delivery, and cost.

Our success in all of these areas is predicated on having dedicated and experienced leadership, starting with the Board of Directors. We are grateful for the service of Mario Longhi, who retired in 2017, and Jack 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 U. S. Steel Board of Directors. Our company is fortunate to be guided by a Board that is invested in and enthusiastic about our future.

In closing, we recognize and appreciate the support we've received from our many stakeholders, including our customers, suppliers, unions and all of you, our stockholders. Our commitment to creating real, sustainable value for you is as strong as the products we make every day.

We encourage our stockholders to vote your shares on the proposals discussed in the accompanying proxy statement. Your involvement and 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 goals. Now, let's get back to work – safely helping our customers be successful.

Sincerely,

Strategy Supports Customers With:

March 12, 2021
DEAR FELLOW U. S. STEEL STOCKHOLDERS:
[MISSING IMAGE: tm212306d1-ph_davidtxtpn.jpg]
2020 was also a year of great resiliency, community and innovation across the globe, including at U. S. Steel. In its 120-year history, U. S. Steel has been an icon of American industry and has sustained itself through national and global crises. This past year proved no different, as we were tested by the global pandemic and its far-reaching impact. We emerged from 2020 stronger, more focused on our customers, confident in the future, and on a trajectory towards sustainable change. We completed 2020 with a 48% total shareholder return for the year, and we are well poised to generate long-term value for years to come.
At the onset of the pandemic, we quickly implemented our crisis response plan and articulated our priorities throughout our organization and to our stakeholders: protect lives and livelihoods; prioritize cash and liquidity; and remain focused, but flexible, in achieving our Best of Both strategy to secure our future. Guided by our S.T.E.E.L. Principles, these goals were the anchor in all our decision-making.
Shortly before penning this letter, we announced that U. S. Steel completed the acquisition of Big River Steel and executed on the cornerstone of our Best of Both strategy to produce the most advanced sustainable steel products. Adding Big River Steel to our footprint propels us forward in all of our critical success factors – moving up the talent curve, moving down the cost curve and winning in strategic markets – as well as towards achievement of our sustainability goals. We proved to ourselves and our stakeholders that despite the severe market downturn, our strategy is the right one for U. S. Steel and our stockholders, and we have a strong and resilient business foundation in place upon which to execute, even in a volatile and uncertain market environment.
Protecting Lives and Livelihoods
Safety First has always been the north star by which we operate, and while the pandemic created a new set of health and safety issues to address, our strong safety culture and processes already in place allowed us to respond quickly and effectively. As a critical infrastructure industry, U. S. Steel was deemed an essential industry and we continued to operate in the U.S. and Slovakia, without disruption for the entirety of 2020. Ensuring our employees had the information and equipment necessary to protect themselves was a top priority. We immediately implemented enhanced sanitization protocols, provided necessary protective equipment, and issued regular and consistent communications. For our employees who work in our administrative offices and headquarters, we quickly moved to a full-time work from home schedule, a cultural and technological shift that was completed in a matter of weeks. Many of the changes we made to respond to the pandemic will likely remain part of our culture, as we’ve discovered that we can be physically distant but socially connected and incredibly productive. We’re also using technology to connect with our customers, as well as engage our employees. We are leveraging technology to work smarter, safer and more sustainably. You can read more about our health and safety response to the pandemic on page 7.
We also remained focused on our day-to-day safety measures. Our robust safety management system serves as the foundation for our operations. In 2020, we achieved a record-breaking safety performance, with 0.07 Days Away from Work. This remarkable performance bests industry standards and is a testament to the commitment of our employees to achieve a zero-injury environment.

[MISSING IMAGE: tm213506d1-ph_pricashpn.jpg]
Prioritizing Cash and Liquidity
Market uncertainty and demand challenges in 2020 also necessitated financial discipline. During the first and second quarters, many of our large automotive customers had stopped production due to the pandemic. Other industry customers were experiencing significant decline in demand, and our Tubular customers were dealing with disruptions in the oil and gas market. We were on a path to use a significant amount of cash, but quickly focused the organization around difficult but necessary decisions to temporarily idle facilities, pursue working capital actions and reduce capital spending. We were also able to monetize certain excess and non-core assets to generate additional cash by selling real estate and entering into long-term iron ore pellet supply agreements. By taking these disciplined actions and focusing on ensuring sufficient balance sheet strength, we were able to navigate the market decline and emerged 2020 in a much stronger cash and liquidity position than expected, able to execute our strategy and respond to our customers’ changing needs.
Remaining Focused, but Flexible, in Achieving our Best of Both Strategy
We remained unwavering in our commitment to achieve our Best of Both strategy. In 2019, we took the first step in uniting the most advantageous elements of the integrated and mini mill technologies by taking a minority interest in Big River Steel. We completed 2020 by exercising our option to purchase the remaining interest in Big River. This acquisition allows us to complement our innovative products with the Big River cost efficiency and process innovations to provide an unmatched value for our customers. This past year we also completed construction on EAF#1 at our Fairfield operations, adding electric arc furnace capability to our footprint to support our Tubular operations. And, we completed construction of the continuous galvanizing line at our PRO-TEC joint venture, which will provide superior finishing capabilities for our differentiated line of advanced high strength steels. These investments will fundamentally change our business model and allow us to manufacture the steels of the future – ones that are produced with less carbon, and are lightweight and environmentally friendly, while maintaining the strength and durability our customers, and their customers, need.
Representing and Responding to our Stockholders
This last year also provided us many opportunities to engage with our stockholders through a variety of platforms to understand your views and priorities, and to update you on our progress to create long-term value for all our stakeholders. We believe in rewarding strong individual and company performance and use these engagements to ensure our stockholders understand how we construct and implement a strong pay for performance alignment. We’ve also enhanced our proxy disclosure in this regard. You can read more about our robust stockholder engagement on page 30.
The Board, in representing your interests, is constructively engaged with management in our overall strategy and business priorities. Active board refreshment has brought new ideas and added breadth of perspectives and experiences to address emerging issues and ensure effective corporate governance and strategic oversight. This past year we welcomed Jeh Johnson and Tracy Atkinson to our Board. We are also grateful for the service of Patricia Diaz Dennis, Dan Dinges and Stephen Girsky, each retiring from our Board as of the 2021 annual meeting.

OVERVIEW OF VOTING MATTERS

Stockholders are being asked to vote on the following matters at the 2018 Annual Meeting of Stockholders:

Cautionary note regarding forward-looking statements
This document contains information that may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend the forward-looking statements to be covered by the safe harbor provisions for forward-looking statements in those sections. Generally, we have identified such forward-looking statements by using the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “target,” “forecast,” “aim,” “should,” “will,” “may” and similar expressions or by using future dates in connection with any discussion of, among other things, operating performance, trends, events or developments that we expect or anticipate will occur in the future and statements expressing general views about future operating results. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are not historical facts, but instead represent only the Corporation’s beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of the Corporation’s control. It is possible that the Corporation’s actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements. Management believes that these forward-looking statements are reasonable as of the time made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made. Our Corporation undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our Corporation’s historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to the risks and uncertainties described in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, and those described from time to time in our future reports filed with the Securities and Exchange Commission (“SEC”). References to “we,” “us,” “our,” the “Corporation,” and “U. S. Steel,” refer to United States Steel Corporation and its consolidated subsidiaries.

2017 HIGHLIGHTS AND ACCOMPLISHMENTS (PAGE 23)

Earning the Right to Grow and Driving 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.

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

KEY EXECUTIVE COMPENSATION PROGRAM PRACTICES (PAGE 27)PROXY SUMMARY

OUR RESPONSE TO COVID-19 PANDEMIC

Compensation Governance Practices
The Compensation & Organization Committee (the "Committee"“Compensation Committee”), which consists solely of independent directors, has implemented the following best practices with respect to executive compensation:

Considers the results of the most recent say-on-pay advisory vote by stockholders and has implemented proactive communications with stockholders to gain input and feedback when making executive compensation decisions
Undertakes a goal setting process that is used to arrive at rigorous short-term and long-term performance goals under our incentive plans that are aligned to key corporate strategic and financial goals
Engages in and leads a robust CEO performance evaluation process
Engages and consults with its own independent compensation consultant
Has established formal selection criteria for the executive compensation and relative TSR peer groups and annually reviews peer group composition
Annually reviews tally sheets analyzing executive compensation levels and structures, including amounts payable in various termination scenarios
Annually reviews the risks associated with our compensation programs and has implemented various risk mitigating practices and policies, such as:

    Targeting the majority of our executives' compensation in long-term performance based awards using multiple equity and cash vehicles

    Implementing rigorous executive stock ownership and holding requirements

    Utilizing multiple performance measures that focus on company-wide metrics and placing a cap on potential incentive payments
Our Change in Control Severance Plan establishes a "double trigger," requiring participants to be terminated without "cause," or voluntarily "for good reason" following a change in control prior to receipt of any payment of severance benefits
Maintains a "clawback" policy that applies to executive officers and provides for the recoupment of incentive awards under certain conditions in the event the Corporation's financial statements are restated
Maintains Anti-Hedging and Pledging Policies that prohibit all employees and directors from engaging in any transaction that is designed to hedge or offset any decrease in our stock price and prohibits executive officers and directors from pledging our stock as collateral for a loan or holding shares in a margin account
Prohibits payment of tax gross-ups to any executives for any payments relating to a change in control

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.

No excise tax gross ups for change in control payments

No guarantee minimum payout of annual or long-term performance awards

No repricing of options

No hedging transactions, short sales or pledging of our common stock by our directors or executive officers

No dividends or dividend equivalents on unearned RSUs or performance shares

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 knows that to be a good corporate citizen is not only the right thing to do, but also is essential to our success. We are more than a global leader in the steel industry; we are your friends, neighbors and 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

personal responsibility, our employees are making a daily commitment to follow safe work practices, look out for the safety of co-workers and ensure safe working conditions for everyone. We continue to enhance our safety practices for both employees and contractors, as we pursue our zero safety incident goal.

Ensuring the safety of the environment in which we work is equally important. We recognize that the earth 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 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.

OUR RESPONSE TO COVID-19 PANDEMIC
The spread of the novel coronavirus designated as COVID-19 (“COVID-19”) pandemic across the globe significantly impacted global markets and nearly every industry, U. S. Steel included. We quickly recognized the uncertainty and potential severity the pandemic would cause and implemented our crisis response plan. Overseen by our Board of Directors, and led by our executive team, we implemented a comprehensive and adaptive response to the pandemic focused on protecting lives and livelihoods, preserving cash and liquidity, remaining nimble to execute our strategy and supporting our customers and communities, all in line with our foundational S.T.E.E.L. Principles. Some of the measures we implemented and continue to practice include:

Issuing weekly communication, including preventive tips, and a dedicated website for employees and their families

Providing employees with protective equipment, masks, and sanitizing and cleaning supplies and enhanced cleaning frequency

Limiting outside visitors to our facilities, restricting access for non-essential vendors, suppliers and contractors

Actively managing physical distancing while at work, including no meetings or gatherings of greater than 10 individuals

Working from home for employees in our administrative offices and headquarters

Intensifying our focus on preserving cash and proactively raising approx. $1.7 billion of incremental capital to support our balance sheet

2021 PROXY STATEMENT7

U. S. Steel Leads 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 investigation under Section 232 of the Trade Expansion Act of 1962 to determine the effects of steel 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 the DOC, the U.S. International Trade Commission (ITC), the Administration, Congress, U.S. Courts, the World Trade Organization, and in the public arena.


In addition to defending the 2016 AD/CVD orders on hot-rolled, cold-rolled, and corrosion-resistant steel, U. S. Steel has 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 in September 2016, the DOC preliminarily found that imports of cold-rolled and corrosion-resistant steel 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 will continue to aggressively and strategically use U.S. trade laws to address unfair import competition.

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

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.

However, the CEO may remain on the Board after retirement as an employee, at the Board’s request, through the last day of the month in which he or she turns 70. All directors who undergo a significant change in their business or professional careers must volunteer to resign from the Board. Ms. Patricia Diaz Dennis, a current director, will retire from our Board at the Annual Meeting under this policy.

GRAPHICDIRECTOR LIMITATIONS ON OTHER BOARDSThe Board recommends a vote "FOR" the election of each nominee.

SelectionOur Corporate Governance Principles limit the number of Director Nomineesother public company boards our directors may serve on to five, and for currently serving public company CEOs, to three. Our Board of Directors waived this limit for Stephen Girsky, who serves as Chief Executive Officer of VectoIQ Acquisition Corp. II, a special purpose acquisition company (SPAC) listed on NASDAQ, as of January 2021. In making this determination, our Board considered many factors, including the significant differences in a SPAC CEO and a public operating company CEO. The SPAC has no employees and no assets other than invested cash. It does not require the same day-to-day management as a traditional public company operating company does. Additionally, the SPAC position inherently is time-limited, and once an investment partner is selected, Mr. Girsky does not intend to serve as CEO of the surviving public company. Mr. Girsky decided not to stand for re-election and his term will expire as of the Annual Meeting.

SELECTION OF DIRECTOR NOMINEES

The Corporate Governance & Public PolicySustainability Committee is responsible for identifying nominees for election to the Board. The Corporate Governance & Public PolicySustainability 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 PolicySustainability 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,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.

CORPORATE GOVERNANCEBOARD LEADERSHIP STRUCTURE


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'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, then the independent directors annuallywill elect from among themselves

a Lead Director. The Chairman (or Lead Director) is elected annually by the Board. If the Chairman of the Board is independent, then 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

perform other duties as the Board may from time to time designate.

For example, the charter of the Compensation & Organization Committee gives it responsibility for assessing whether the Corporation'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's businesses and operations.

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 aligned with the Best of Both strategy. Annually, our Board reviews and approves our capital authorization and spending budgets, which are designed to strategically deploy capital intended to facilitate investments

At least twice annually, ourplanning at each of its quarterly meetings. Our full Board reviews senior

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.

The Board and the Compensation Committee are responsible for monitoring our management succession and leadership development plans. Our Corporate Governance Principles require all executive officers to retire at age 65. The Compensation Committee may, in its discretion, waive that requirement, and did waive it for Mr. Burritt and Ms. Breves.
BOARD OVERSIGHT OF CULTURE AND HUMAN CAPITAL MANAGEMENT

Moving up the talent curve is a critical success factor to achieving our corporate strategy. Because we believe U. S. Steel will only be able to successfully execute on its strategic priorities with the full engagement of a talented workforce, the Board and its committees oversee human capital management. The Board receives periodic reports on the results of employee engagement or inclusion surveys, the collective bargaining process and relationship between management and the United Steelworkers, relevant workforce metrics, including related to inclusion and diversity, talent development, and pay equity analysis and hiring practices.
The Board also believes that visits to facilities enable it to judge the Corporation’s culture first-hand. While safety concerns have limited visitation to our facilities, as part of our onboarding process, each new director elected in 2020 visited our Mon Valley Works facility. These experiences enable the Board to judge whether the Corporation is adopting business practices that create the engaged and stable workforce needed to achieve its long-term strategy.

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'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) listing standards and the U.S. Securities and Exchange Commission (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. 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 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 2017 was less than 2% of WESCO's annual gross revenues. As a result, the Board concluded that these transactions would not affect Mr. Engel's independence.

Additionally, the Board considered the fact that U. S. Steel indirectly sold products to Cabot Oil & Gas Corporation ("Cabot") in 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's annual gross revenues. Accordingly, the Board concluded that these transactions would not affect Mr. 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'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'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 Audit Committee annually requests PriceWaterhouseCoopers 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'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 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's chairman, Murry S. Gerber and Stephen J. Girsky meet the SEC's definition of audit committee financial expert.

At U. S. Steel, we have a long-standing commitment to the safety and health of the men and women who work in our facilities. Every employee deserves to return home safely at the end of every day, and we are working to eliminate all injuries and incidents. In addition, the psychological safety of all employees is important to us. We have combined physical safety and psychological safety into the construct of 360° safety. Ensuring a safe workplace also improves productivity, quality, reliability and financial performance. By making safety and health a personal responsibility, our employees are making a daily commitment to follow safe work practices, look out for the safety of co-workers and ensure safe working conditions for everyone. A “Safety First” mindset is as essential to our success as the tools and technologies we rely on to do business. This past year, we relied on our strong safety culture to ensure the health and safety of our employees during the COVID-19 pandemic.
Our objective is to attain a sustainable zero harm culture supported by leadership and owned by an engaged and highly skilled workforce, empowered with the capabilities and resources needed to assess, reduce, and eliminate workplace risks and hazards. In support of these objectives, we have developed an enhanced Safety Management System, initiated new safety communication methods and enhanced contractor safety processes. One of our most important safety protocols is our fatality prevention audit program. These proactive assessments by positionof the processes and protocols we have in place, and adherence to them, to avoid fatalities and severe injuries are conducted annually at the enterprise level and more frequently at each of our facilities. We assess our safety performance through a variety of lagging and leading indicators, including OSHA DAFW. This measurement allows us to evaluate the frequency of injuries sustained at our facilities requiring an employee to stay at home for each element of compensation and for compensationmore than one day. U. S. Steel has achieved record-safety performance in this measurement in the aggregate;

Reduction of Greenhouse Gas Emissions
In 2019, as part of our strategy to become the Best of Both in the steel industry, U. S. Steel announced its commitment to reduce greenhouse gas ("GHG") emissions intensity across its global footprint. U. S. Steel set a goal to reduce its global greenhouse gas emissions intensity by 20% as measured by the rate of CO2 equivalents emitted per ton of finished steel shipped, by 2030 based on 2018 baseline levels. This target will apply to U. S. Steel’s global operations.
These reductions are equivalent to the amount of CO2 being generated by more than 850,000 average-sized homes each year. By creating targeted carbon reduction initiatives to accelerate our transformation toward a future of sustainable steel, we create value for all stakeholders.
The carbon intensity reduction target reflects our continued commitment to improvement in production efficiency and the manufacture of products that are environmentally friendly. In addition to a commitment to reduce its own greenhouse gas emissions intensity, U. S. Steel is committed to helping its customers achieve their environmental goals. Our industry-leading XG3TM advanced high-strength steel enables automakers to manufacture lighter weight vehicles that meet federal Corporate Average Fuel Economy (CAFE) standards with reduced carbon emissions. As part of our innovation efforts, we continue to look at new steelmaking technologies so that we can produce green steels and further reduce carbon emissions.

Director CompensationDIRECTOR 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 employeesThe goal 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.capabilities to serve as directors . 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.

Directors who are employees of U. S. Steel receive no compensation for their service on the Board.

2020 Director Compensation
For 2017, non-employee directors were paid an2020, the Board maintained the annual retainer fee of  $240,000. Committee Chairs$265,000 after following a robust benchmarking review process, described below. Each committee chair received an additional $20,000 and the Chairman of the Board were paidreceived an additional annual fee of $20,000 and $50,000, respectively.$100,000 retainer. No meeting fees or committee membership fees are paid.

paid. In response to the challenges of the pandemic, the Board temporarily decreased their annual retainer for half the year by 20% for the maximum cash portion.

Deferred Compensation Program
Under our Deferred Compensation Program for Non-Employee Directors, each non-employee director is required to defer at least 50%a minimum of 55% 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

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT31

CORPORATE GOVERNANCEDIRECTOR COMPENSATION
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.

The Board and management believe that such deferral, by continually building each director’s equity interest in the Corporation, provides a meaningful continued interest in the Corporation that is tied to the stockholders’ interest because the stock issued upon a director’s departure from the Board reflects all changes in the market value of U. S. Steel common stock from the date of deferral.

Non-Employee Director Stock Program

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 dayssix months following the first date of his or her service on the Board.

Compensation Review Process
The Corporate Governance & Public PolicySustainability Committee reviews and sets director compensation on an annual basis. In November 2016, the committee reviewed information and recommendations from
Annually, Pay Governance, an independent compensation consultant, presents a benchmarking report on director compensation for the same comparatorpeer 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 thatevaluates the plan design wasand compensation levels to ensure they are consistent with market trends but that the amountand makes recommendations of our directors' annual base retainer, which was set in 2011, was below the 25th percentile and significantly below the 50th percentile of both comparator groups. The Corporate Governance & Public Policy Committee recommended, 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 noany appropriate 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 OFFICERSUNITED STATES STEEL CORPORATION

2021 PROXY STATEMENT

The Board has adopted stock ownership and holding requirements for executive officers. These requirements are described under the caption "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'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's equity interest in the Corporation, provides a meaningful continued interest in the Corporation that is tied to the stockholders' interest because the stock issued upon a director'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 26, 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.

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT33

CORPORATE GOVERNANCEDIRECTOR INDEPENDENCE
DIRECTOR INDEPENDENCE
The Board affirmatively determined that all non-employee director nominees for 2021 are independent within the definitions of independence of both the New York Stock Exchange (“NYSE”) listing standards and the U.S. Securities and Exchange Commission (“SEC”) standards for Audit Committee members. U. S. Steel has incorporated the NYSE and SEC independence standards into our own categorical standards for independence. The Board has affirmatively determined that none of the directors or nominees for director, other than our CEO, Mr. Burritt, has a material relationship with the Corporation. The Board made this determination based on all relevant facts and circumstances.
AUDIT COMMITTEE The Board also determined that each member of the Audit Committee: (1) did not accept directly or indirectly any consulting, advisory, or other compensatory fee from the Corporation or any of its subsidiaries, and (2) was not an affiliated person of the Corporation and all holdersor any of its subsidiaries. Therefore each member satisfied the NYSE’s enhanced independence standards for audit committee members.
COMPENSATION COMMITTEE The Board also determined that class of equity securities receive the same benefit on a pro rata basis; (v) transactions where the rates or charges involved are determined by competitive bid; (vi) transactions involving the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental regulation; and (vii) transactions involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture or similar services.

There were no transactions that required approvalmember of the Compensation Committee has a relationship to the Corporation that is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member. Therefore, each member of the Compensation Committee satisfied the independence requirements of NYSE listing standards.

For more information, our standards of director independence are located in our Corporate Governance & Public Policy Committee under this policy during 2017.

Under Section 16(a) of the Securities Exchange Act of 1934, our directors and executive officers and persons holding more than 10% 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.

Certain 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.

Executive Summary
38Executive Summary

Our executive compensation program is designed to attract, reward and retain executives who make significant contributions through operational and financial achievements aligned with the goals and philosophy of our long-term strategy. The Compensation & Organization Committee (the "Committee") is guided by five compensation principles highlighted below and discussed in more detail on page 28.

Align Pay with Stockholder Interests

Pay Fair and Competitive Compensation

Link Compensation to Company Performance and Strategy

Retain Executives

Provide Equity-Focused and Tax-Efficient Rewards

These principles reflect a strong pay-for-performance culture. Furthermore, the structure of our compensation program and the pay outcomes for executives demonstrate our commitment to linking compensation to company performance and strategy.




Earning 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, 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.

COMPENSATION DISCUSSION AND ANALYSISEXECUTIVE SUMMARY
EXECUTIVE SUMMARY
EXECUTING OUR STRATEGY TO CREATE LONG-TERM STOCKHOLDER VALUE
In 2018 we launched our Best of Both strategy to allbecome the best steel company by leveraging the advantages of integrated steelmaking – iron ore and product innovation – with the advantages of mini mills – process innovation and cost efficiency. Our strategy is to create long-term stockholder value by pursuing a business model that is resilient to market volatility and is profitable through the business cycle.
In 2020, we executed critical components of our Best of Both strategy, none more transformational than the full acquisition of Big River Steel. We first invested in Big River Steel in 2019, with an option to purchase the remaining equity within four years. During the pandemic, we refocused our efforts isto exercise that option in 2020, when the pricing was fixed and favorable to us. During our belief thatfirst year as partners, we must operate as a principled company committedsuccessfully trialed 11 U. S. Steel grades of steel at Big River Steel, with its low carbon emissions intensity production process, validating the Best of Both thesis.
In addition to a codethe Big River Steel acquisition, we also completed additional actions in 2020 moving us towards our Best of conduct that is rooted in our Gary Principles and our core values, the most important of which is safety Both future:
of our employees, our environment, and our facilities and equipment. These core beliefs have served us well for much of our history, and our commitment to them remains as strong as the products we 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

In 2020, we enhanced our footprint from 100% blast furnace operation, to one with three electric arc furnaces – lower cost and lower carbon production. This transformation in footprint and technology enables U. S. Steel to produce the steels of the future – those that are BEST for customers, BEST for consumers, and BEST for the planet.

COMPENSATION DISCUSSION AND ANALYSISEXECUTIVE SUMMARY
2020 PERFORMANCE HIGHLIGHTS
In spite of market and regulatory hurdles facing our business.

Our executive compensation program has been structured to closely align withpandemic-related challenges, the objectives of the 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.

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.

COMPENSATION DISCUSSION AND ANALYSISEXECUTIVE SUMMARY
RESPONSE TO COVID-19
The global pandemic resulting from COVID-19 has had a significant impact on economies, businesses and individuals around the world. At U. S. Steel we quickly implemented our crisis response plan to respond to challenges and issues posed by the pandemic, and focused our organization around three priorities to guide our actions and decisions through the crisis.
PROTECT LIVES AND
LIVELIHOOD
Our strong safety culture provided a solid foundation upon which we implemented additional cleaning, sanitizing, and protective protocols to ensure the health and safety of our employees and the continuity of our operations.
PRIORITIZE CASH AND
LIQUIDITY
To bolster liquidity in the uncertain environment, we heightened our focus on managing the business to preserve cash, and we accessed the capital markets to raise an additional $1.7 billion of capital. We also quickly adjusted our capital spending to align with market conditions.
REMAIN FOCUSED, BUT FLEXIBLE TO ACHIEVE OUR BEST OF BOTH
STRATEGY
The uncertain and challenging environment strengthened our resolve to execute our Best of Both strategy as quickly as prudently possible. The need to support our customers, continue to innovate and move towards the future was highlighted by the pandemic, and management decisively executed this goal through disciplined, focused and intentional actions.
2020 Compensation-Related Impacts of the Pandemic
Throughout the year, the Compensation Committee was highly focused on the impact of the pandemic to the business, and helped move us another step closerrelated compensation and benefits impacts to achieving sustainable profitability. We made good progressemployees. The Committee received regular updates from management on employee compensation, benefits and other arrangements implemented in 2017,response to the pandemic.
For example, management worked closely with the USW to ensure that furloughed workers had access to full benefits, including health insurance and striveretirement benefits, and provided flexibility to employees who were unable to work or preferred alternative work arrangements due to high risk family members.
2020 COVID-19 Compensation-Related Actions

As part of our cash preservation efforts, our executive officers volunteered to temporarily reduce their base salaries for half the year by 25% for our CEO and 10% for other executives, and suspended all company contributions to our 401(k) plan for salaried employees. These recommendations were endorsed by the Compensation Committee.

In response to the challenges of the pandemic, our Board of Directors temporarily decreased their annual retainer for half the year by 20% for the maximum cash portion.

The significant impact of the pandemic on our business resulted in a below threshold performance level for the Annual Incentive Compensation Plan EBITDA performance goal. This performance was monitored throughout the year, but given the ongoing uncertainty in the business, no goal changes were made. The Compensation Committee considered alternative methods for evaluating performance, and ways to ensure management was compensated commensurate with the performance in exceptionally challenging circumstances, while balancing the interests of all stakeholders, and awarded our NEOs (other than the CEO) a one-time award, as described on page 46.

COVID-19 Impact: Each executive officer’s base base salary was reduced for greaterpart of the year in response to and as a show of leadership during the immediate onset of the pandemic. In determining actual awards under the AICP, the Compensation Committee determined to base the awards on earned base salary, without giving effect to the temporary base salary reduction.
Compensation Outcomes: Payouts Reflect Corporate Performance
The Compensation 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’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 Compensation Committee for the annual and long-term incentive plans.

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 predictabilitystockholder feedback, and our ability to compete effectivelydecisively take action and incorporate their perspectives in our programs.

In each year from 2017-2019, we received over 94% approval of our executive compensation program. The Compensation Committee recognizes that the 74.8% support for our executive compensation in 2020 was lower than our typical votes in recent years, and we again extended invitations in 2020 to our stockholders to hear their views.
2020 Stockholder Engagement and Actions Taken
In 2020, we reached out to holders of approximately 40% of our outstanding shares and meetings were held with the eight investors who accepted our invitation, representing approximately 20% of our outstanding stock. During these meetings, we heard that our stockholders are generally supportive of our executive compensation program and the link between pay and performance embedded in our executive compensation program. One recurring theme of our engagements on compensation has been the challenge of addressing external market conditions that could have a dispositive impact on the Corporation’s earnings.
Over the years we have implemented several changes to our compensation practices to further align pay with performance, reduce the volatility in the industry. As we revitalizemeasures under the program to ensure executive compensation is tied to controllable actions and respond to stockholder feedback. We also heard from stockholders that the change to include annual components in the TSR calculation for our assets, we expectLTIP award raised concerns that the award was not long-term in nature. We have expanded disclosure around the rationale behind that change to increase profitability, productivityprovide stockholders with more information upon which to assess our program structure.
Finally, our engagements often focus on the health and operational consistency, and reduce volatility.

In addition to investing in improvementssafety of our leadersemployees and current assets, we'rehow executives are judged in these areas. We have also enhanced our disclosure in this area to provide more transparency to stockholders about how individual performance is assessed.

2020 COMPENSATION DECISIONS ALIGN PAY AND PERFORMANCE
In making decisions regarding 2020 compensation, the Compensation Committee underwent a robust analysis and thoughtful process. In the beginning of the year, the Compensation Committee’s independent consultant reassessed the roles and responsibilities of our executive officers. That review resulted in a change to the median total target direct compensation for executive officers as compared to the executive compensation peer group. The Compensation Committee, in order to motivate and incentivize executives, particularly during a time of strategic transition when retention of executives is of utmost importance, normalized executive total target direct compensation by adjusting target amounts for base salary, AICP opportunity and LTIP grant values.

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT45

COMPENSATION DISCUSSION AND ANALYSIS2020 COMPENSATION DECISIONS ALIGN PAY AND PERFORMANCE
In making target compensation decisions, the Compensation Committee also took into consideration U.S. Steel’s 2019 performance, the industry market environment expected for 2020, continued development and execution of our global workforcelong-term strategy, and assumption of additional duties in connection with executive leadership changes and the innovation that will create tomorrow's steel solutions today. We've continued our aggressive efforts around the developmentresponsibilities 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 – EAGLE SFHTM and sold our first orders of USS-LIBERTY LDTM connections to meet the needseach of our customersNEOs.
Actual AICP award decisions were made following the completion of 2020 and based on achievement of rigorous corporate EBITDA and CCC goals, as well as individual performance objectives. While Corporate EBITDA targets were not achieved, the European segment achieved above target EBITDA performance, which comprises a portion of Mr. Bruno’s award. Additionally, U. S. Steel achieved the maximum performance target for Cash Conversion Cycle.
One-Time Bonus for Extraordinary Team Leadership During the Pandemic
The Compensation Committee believes the AICP design is the appropriate short-term design to incentivize executives to achieve profitability and cash management that aligns with stockholders’ interests, and generally disfavors one-time cash awards. However, the Compensation Committee recognized that 2020 was not an ordinary year and determined that the usual formula did not serve as a full and adequate measurement of performance to drive stockholder value or reward performance. While EBITDA performance fell short of targeted goals that were set in January 2020 prior to the pandemic, as the year unfolded with unprecedented challenges and market disruption, the Compensation Committee determined that EBITDA did not serve as the broad measurement of annual performance or creation of stockholder value that it typically does. The severe impacts to the economy caused by the pandemic early in the year, including abrupt closure of auto facilities and the global oil and gas industrycrisis, made EBITDA targets unachievable early on. Recognizing the substantial commitment of our executives navigating the challenges, the Compensation Committee determined that payout beyond the AICP formula was warranted. However, the Compensation Committee determined not to adjust the EBITDA metric or performance goals that were negatively impacted by the pandemic.
Major 2020 Achievements
In recognition of that dynamic, the Compensation Committee considered the actions management took and how they performed to sustain the deep trough and perform in the recovery, including these notable achievements:

2020 total shareholder return of 48%, outperforming the S&P 500 and the majority of our steel company peers

Significantly exceeding pandemic-adjusted expectations for year-end cash and liquidity

Continuity of operations through rapid and comprehensive COVID-19 crisis response, including robust health and safety measures and the speedy transition of administrative and headquarters employees to work from home, weeks faster than expected

[MISSING IMAGE: tm212306d1-lc_compesatpn.jpg]
The Compensation Committee also recognized that successfully navigating the pandemic environment was not up to individual performance – it was largely dependent upon exceptional collaboration and execution as a team, with each leader aligned to common purpose. After taking into consideration the performance to navigate the unprecedented challenges, the Compensation Committee awarded each NEO a one-time cash award in amounts shown in the following table. The CEO forfeited approximately $290,000 in compensation through voluntary salary reduction and suspended retirement account contributions, and recommended that he be excluded from such an award. He advocated for an award recognizing the leadership of his team of senior vice presidents. In addition, in recognition of the pandemic challenges faced by employees, including loss of certain retirement compensation, and for the hard work to position U. S. Steel to prosper in the industry recovery, salaried employees were also awarded a one-time cash bonus.
In determining the one-time bonus award amount, the Compensation Committee examined the amount of compensation each executive gave up as a stronger company by 2020.part of the recommended salary reduction and suspension of 401(k) contributions, as well as AICP payouts.


The aggregate annual payment to our NEOs with AICP and the one-time bonus generally does not exceed 100% of their targeted AICP amount.
The Compensation Committee considers this amount to be reasonable to recognize performance, and aligned with enterprise and stockholder interests.

The Compensation Committee sets challenging operational and financial performance targets to motivate executives to achieve short- and long-term success. To link pay to performance, the Compensation Committee believes it isthat most of an executive’s compensation should be paid in the form of performance- and/or stock-based compensation with a greater emphasis on variable components for the most senior executives who have greater responsibility for the performance of the business.
The Compensation Committee assesses our NEOs on their individual performance related to safety leadership and culture, executing our strategy, progressing on our critical success factors and overall leadership.

COMPENSATION DISCUSSION AND ANALYSISOUR COMPENSATION PROCESS
OUR COMPENSATION PROCESS
Role of the Compensation Committee and Independent Consultant
The Compensation Committee retained Pay Governance, LLC as its independent consultant to alignassist in the evaluation of executive compensation programs and in setting executive officers’ compensation. The use of an independent consultant provides additional assurance that our executive compensation programs are reasonable and consistent with the Corporation’s objectives. The consultant reports directly to the Compensation Committee and does not perform services for management without the express approval of the Compensation Committee. There were no services performed by the consultant for management in 2020.
The consultant participates in the Compensation Committee meetings, including executive sessions, and regularly advises the Compensation Committee with respect to compensation trends and best practices, plan design, and the reasonableness of individual compensation awards.
For our CEO’s compensation, the Compensation Committee makes its determinations based upon its evaluation of the CEO’s performance and with input from its consultant. Each year, the Compensation Committee reviews with the Board of Directors the CEO’s goals and objectives, and the evaluation of the CEO’s performance against the prior year’s goals and objectives. The CEO does not participate in the presentations to, or discussions with, the Compensation Committee in connection with the setting of his compensation.
2020 Pay Governance Services
During 2020, Pay Governance performed the following specific services:

provided presentations on executive compensation trends, best practices and recent developments;

advised on compensation program design;

prepared competitive assessments by position for each element of compensation and for total compensation for our executives; and

reviewed the peer groups used for benchmarking compensation and measuring performance for purposes of the relative TSR Performance Awards.
The Compensation Committee has assessed the independence of the consultant pursuant to the NYSE listing standards and SEC rules and concluded that no conflict of interest exists that would prevent the consultant from serving as an independent consultant to the Compensation Committee.
Compensation and Risk Management
The Compensation Committee’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 awarded in equity, make up the majority of our executives’ compensation;

Capped Awards: Payments under our AICP are capped at 230% of target and our long-term performance awards are capped at 200% of target;

Performance Metrics: Different metrics are used in the annual 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 base salary.
For these reasons, the Compensation Committee concluded that our 2020 compensation and organization policies and practices are not reasonably likely to create a risk that could have a material adverse effect on the Corporation.
Tally Sheets
The Compensation Committee uses tally sheets to evaluate the total compensation and projected payments to the NEOs under various termination scenarios. This analysis is undertaken annually to assist the Compensation Committee in determining whether the compensation package of each NEO is appropriately aligned with our compensation philosophy and the compensation practices of our peers.

52UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSISOUR COMPENSATION PROCESS
Peer Groups
The Compensation Committee also considers relevant market pay practices in its decision making process. The Compensation Committee uses the peer group data below as a frame of reference to guide executive compensation decisions. The Corporation uses two peer groups:

Executive Compensation Peer Group. This peer group is used to benchmark and assess the competitiveness of the compensation of our NEOs.

Performance Peer Group. This peer group, which is more industry focused, is used to evaluate the long-term performance of the Corporation for the relative TSR performance award. The performance peer group is used 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.
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 to 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. In setting the executive compensation peer group, the Compensation Committee considered a set of broader, industrial peers who might compete with the goalsCorporation 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. The Compensation Committee aims to set executive compensation targets in line with the executive compensation peer group median.
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; and

elimination of companies with unusual compensation practices (e.g., company founders who receive little or no compensation and companies that are subsidiaries of other companies).
The 2020 executive compensation peer group consisted of the following companies:
AK Steel Holding CorporationEaton Corporation plcParker-Hannifin Corporation

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

The elements of compensation provided to our executives include: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'sCompensation Committee’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.

Base Salary

Variable, at-risk compensation accounted for 74% of our CEO's target compensation in 2017. Based on this strong pay-for-performance alignment, realizable compensation for our CEO over the last three yearsBase salary is 42% above the target value granted during the period.

Compensation Decisions and Outcomes Demonstrate Alignment with Performance

The Committee approved the following items based on several factors, including: the Corporation's 2016 performance; outlook for 2017 performance; continued development and execution of the long-term strategy; assumption of additional duties in connection with executive leadership changesday-to-day activities and responsibilities of each of our NEOs; among other criteria.

CEO Compensation Decisions for 2017

Salary:  In connection with his promotionposition. Base salary is set at a market competitive level to CEO,attract and retain talent. Actual salary levels take into account factors such as 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. Burritt's target pay increased in connection with his elevation to the role of President & CEO, though it remains lower than the total target compensation of our former CEO by $4 million. The amounts shown for Mr. Burritt in the Summary Compensation Table reflect his service for a portion of the year as Executive Vice President & Chief Financial Officerexecutive’s contribution, individual qualifications and Chief Operating Officer.

The Committee believes pay decisions for 2017 demonstrate the significant link between executive compensationexperiences, and company performance, and accountability of our executives to deliverinternal 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's commitment to performance alignment. This strong pay-for-performance alignmentSteel. Base salary is clearly reflectedpaid 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 94% of target, and no payouts were made in 2015 based on the 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 2014 performance awards, 2014-2016 or 2015-2017 ROCE performance awards and below target payout for the 2015-2017 TSR performance awards.

Compensation Discussion and Analysis – Executive Summary

Commitment to Stockholder Engagement on Executive Compensation

In 2017, we continued our long-standing engagement efforts with our stockholders both during and outside of the proxy season. In each of the last two years, we've met with or held telephonic meetings with stockholders representing over 20% of our outstanding stock. These discussions focused primarily on our business strategy and the alignment of our compensation program to our strategy and company performance. In addition, 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 have 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 2017 meetings, we determined that our stockholders are supportive of the strong link between pay and performance embedded in our executive compensation program. Over the years, we have implemented changes to our compensation practices to further align pay with performance and enhanced disclosure regarding the rationale behind certain compensation decisions.

Compensation Governance Practices

Our compensation program is designed to promote exceptional performance and align the interests of our executives with the interests of our stockholders while discouraging executives from excessive risk-taking. Our executive compensation is directly aligned with company performance and measurable financial metrics.

Compensation & Organization Committee Practices
Considers the results of the most recent say-on-pay advisory vote by stockholders and has implemented proactive communications with stockholders to gain input and feedback when making executive compensation decisions
Undertakes a goal setting process that is used to arrive at rigorous short-term and long-term performance goals under our incentive plans that are aligned to key corporate strategic and financial goals
Engages in and leads a robust CEO performance evaluation process
Engages and consults with its own independent compensation consultant
Has established formal selection criteria for the executive compensation and relative TSR peer groups and annually reviews peer group composition
Annually reviews tally sheets analyzing executive compensation levels and structures, including amounts payable in various termination scenarios
Annually reviews the risks associated with our compensation programs and has implemented various risk mitigating practices and policies, such as:

    Targeting the majority of our executives' compensation in long-term performance based awards using multiple equity and cash vehicles

    Implementing rigorous executive stock ownership and holding requirements

    Utilizing multiple performance measures that focus on company-wide metrics and placing a cap on potential incentive payments
Our Change in Control Severance Plan establishes a "double trigger," requiring participants to be terminated without "cause," or voluntarily "for good reason" following a change in control prior to receipt of any payment of severance benefits
Maintains a "clawback" policy that applies to executive officers and provides for the recoupment of incentive awards under certain conditions in the event the Corporation's financial statements are restated
Maintains Anti-Hedging and Pledging Policies that prohibit all employees and directors from engaging in any transaction that is designed to hedge or offset any decrease in our stock price and prohibits executive officers and directors from pledging our stock as collateral for a loan or holding shares in a margin account
No payment of tax gross-ups to any executives for any payments relating to a change in control

Compensation Discussion and Analysis

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 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

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

Equity incentives comprise a significant portion of an executive'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 Compensation 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'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.

Provide Equity-Focused and Tax-Efficient Rewards

The largest portion of an executive'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 AICP aligns our executive officers'officers’ compensation with the achievement of annual performance goals that support our business strategy. Typically, the short-termannual incentive awards are paid in cash, but the Compensation Committee retains discretion to provide the award in cash, stock, or a combination of both.

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

the achievement of a pre-determined net sales performance goal, and once funded, actualActual amounts earned are based on the formula illustrated below, with predetermined performance goals based on the achievement of cash flowCCC and earnings before interest, taxes, depreciation and amortization (EBITDA)EBITDA performance measures. Final awards may be increased or decreased based on individual performance. The individual performance factor is based on a percentage of the executive’s target award. The Compensation Committee determined that cash flowEBITDA and EBITDACCC were the appropriate measures to drive the transformation required to achieve our goal of sustainable profitability.

Net SalesDetermines if plan is funded; no payouts are made if net sales goal is not achievedThe Committee sets the funding threshold as a value of net sales to more fully align the objective with the Corporation's focus on shipping profitable tons, rather than on volume produced
Cash Flow*Determines 50% of award payoutFinancial performance measure intended to focus the organization on the generation of the cash required to reduce debt and fund investments that will yield profitable returns in the future
EBITDA**Determines 50% of award payoutFinancial performance measure intended to focus the organization on operating at sustainable, profitable levels
Individual PerformanceModifier; Committee may increase award up to 30% or reduce or eliminate based on individual performanceBased on an assessment of the executive's individual performance, including the contribution to overall corporation results and attainment of operational and strategic goals, and the priorities of profitability, customer focus, operational excellence and building a high performing organization, as well as internal equity fairness, and the impact of significant research, development and innovation
*
Cash flow is defined as earnings before interest, taxes, depreciation, depletion, and amortization (EBITDA) for consolidated worldwide operations, plus or minus changes in current receivables, inventories, and current accounts payable and accrued expenses, less consolidated worldwide capital expenditures. EBITDA for consolidated worldwide operations means earnings (loss) before interest and income taxes as reported in the consolidated statements of operations of the Corporation, plus or minus the effect of items not allocated to segments (excluding post-retirement benefit expenses) as disclosed in the notes to the consolidated financial statements, plus depreciation, depletion and amortization as reported in the consolidated statement of cash flows of the Corporation.

**
Total EBITDA shall mean earnings before interest and taxes as reported in the consolidated statement of operations of United States Steel Corporation, plus or minus the effect of items not allocated to segments (excluding postretirement benefit expenses) as disclosed in the notes to the consolidated financial statements of United States Steel Corporation, plus depreciation, depletion and amortization as reported in the consolidated statement of cash flows of United States Steel Corporation. Segment EBITDA shall mean, for the Performance Period, EBITDA for each business unit. Unless contemplated in the approved performance target, EBITDA excludes charges or credits for business dispositions, acquisitions, asset sales, asset impairments, workforce reductions, shutdowns, and amounts not allocated to business segments.

The target award under the AICP for each NEO is equal to the target percentage applied to the executive's base salary. The following table shows the actual amount awarded by the Committee after consideration of the executive's individual performance.

"Base Salary" for purposes of determining the AICP award is the actual salary earned for 2017. Messrs. Longhi and Bradley served for a portion of the year, and the table above reflects the prorated target AICP award.

(2)
The "Target Award" is the amount that would be paid to the executive assuming the Corporation achieves its target performance objectives and before consideration of individual performance. The target amount for Mr. Burritt was calculated by prorating the applicable target for his service as Chief Financial Officer (100% earned base salary) and Chief Executive Officer (140% earned based salary).

(3)
The "Total Payout Rate" is determined by the Corporation's actual performance measured against the 2017 performance metrics and before individual performance is considered.

Compensation Discussion and Analysis

Setting Corporate Performance Goals and Determining Results

The Compensation Committee sets challenging operational and financial performance targets that drive and motivate executives to achieve short- and long-term success. The Compensation Committee set the target goals for AICP purposes in the first quarter of 2020, using an approach that considers:


prior year’s performance;

expected 2020 financial performance and the annual operating plan;

the impact of planned strategic activities; and

fluctuations in global steel prices and other macroeconomic factors.
In setting the 2020 goals, under the AICP for 2017,Compensation Committee recognized that 2020 financial performance would be challenged to meet or exceed 2019 performance given the trend in global steel prices, and other macroeconomic factors. For 2020, the Compensation Committee considereddetermined that a sufficient degree of stretch existed in the Corporation's performance over the past five years, the annual operating plan for 2017, industry performance, and the Corporation'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 operational 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's balance sheet.target. The goals were considered rigorous when set.
The target performance goal for both EBITDA and Cash Conversion Cycle is set in line with the Corporation’s annual operating plan, and if achieved would result in a significant stretch overpayout of 100% for that component. The Compensation Committee sets the threshold and maximum performance goals establishedat a wide range in 2016.

recognition of the volatile industry in which we operate. Achievement of threshold performance results in a 50% payout, and achievement of maximum performance goals results in a 200% payout.

In addition to determining individualcorporate performance targets, the Compensation Committee approved EBITDA goals
for each NEO.

For the CEO, CFO and CFO,General Counsel, the EBITDA goal is based on the total companycorporate results, which generally measures the operational results of all business segments.

For executives assigned to a specific segment, like Messrs. Bruno and Buckiso, the EBITDA goal is 50% based on the EBITDA goal for that segment and 50% based on total company

corporate EBITDA.

EBITDA (for Mr. Matthews, 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 2017 with a total of $12.25 billion in net sales, therefore the award pool was funded for 2017 because the net sales goal of $8.5 billion was achieved.

The payout rate (prior to adjustment forresult (which does not include 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 2017 payout under the annual incentive compensation plan averaged 104% of target for our NEOs who received a payout, and the average payout for our NEOs over the last three years is 94% of target (in each case, including adjustments made for individual performance).

Setting Individual Performance Goals and Determining Results

Our executive officers may earn up to an additional 30% of their target award (or have their award reduced) based on their individual performance. In determiningaddition to their role in achieving the CEO's annual incentive, the Committee considers, among other things, the CEO'senterprise financial goals, NEOs are evaluated on their individual performance in delivering results for the established value creation drivers of profitability, customer focus, operational excellence and high performing organization. The CEO's individual performance objectives are reviewed by the Committee and approved by the Board. following categories:

Performance CategoryPurpose
SafetySafety of our employees is our top priority and is not compromised. Executives are expected to demand strict compliance to our safety protocols and demonstrate and facilitate safe work practices. Our expanded 360 safety initiative also requires our NEOs to ensure a psychologically safe environment for our employees.
Strategy ExecutionOur NEOs all contribute to the achievement of our strategic goals to create long-term stockholder value. They are expected to act with an enterprise mindset and facilitate alignment throughout the organization with our Best of Both strategy.
Advancing Critical Success Factors
Our NEOs all work towards improving on the three areas that are critical to our long-term success:

Moving Down the Cost Curve

Moving up the Talent Curve

Winning in Strategic Markets
LeadershipAs leaders of U. S. Steel, our NEOs are expected to demonstrate values-based tone at the top and exemplify our S.T.E.E.L. Principles. Ensuring engagement and development within their respective areas of responsibility is essential to U. S. Steel’s future success.
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.

David BurrittLong-Term Incentive Program – 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.

Compensation Discussion and Analysis

Upon assuming leadership of the Corporation, Mr. Burritt quickly focused on realigning and assigning a new CHRO, CFO, and SVP with responsibility for Asset Revitalization, and established a focused execution strategy for safety, quality, delivery and cost to stabilize operations and enable continuous improvement for the Corporation's long-term success. Recognizing the need to develop a high performing organization, he launched the talent development theme of "Pivot to the People," the safety initiative "Culture of Caring," and conducted the first ever comprehensive "Inclusion Survey," while making difficult choices to streamline the organization and upgrade the talent.

In keeping with the intent to improve all aspects of the business, the Board and Mr. Burritt determined that further improvement in the Corporation's culture is needed to ensure the exceptional operational and financial progress made in 2017 endures. In spite of returning to profitability with the best balance sheet in recent years, Mr. Burritt, after discussions with the Board, did not receive his annual cash incentive award for 2017, reflecting Mr. Burritt's personal responsibility for and commitment to creating a workplace climate meeting the highest standards of accountability, fairness, and respect. In 2018, Mr. Burritt will focus on continuing to drive strong operational and financial excellence while building a highly engaged workforce and high performance culture.

He is working closely with his team, bringing new thinking and perspective across the organization to accelerate the transformation of U. S. Steel to a stronger and more profitable company. Mr. Bradley has meaningfully contributed to the stability and consistency of the financial performance across the Corporation. He quickly established himself as a key member of the leadership team.

Douglas Matthews – Mr. Matthews led the North American Flat-Rolled Industrial, Service Center and Mining Solutions (ISC&M) commercial entity in 2017. Through his continued successful implementation of our transformational strategy, the ISC&M team contributed to noteworthy North American Flat-Rolled EBITDA improvement in 2017. Operations led by Mr. Matthews also meaningfully improved service to our customers, including a 22% improvement in customer claims for industrial customers and significant delivery improvements for all end users. Mr. Matthews also oversaw the successful restart of Keetac mining operations and the Granite City hot strip mill. He also implemented meaningful employee engagement to achieve strong safety performance, particularly in the second half of the year. Mr. Matthews'

ability to maintain collaborative relationships with his peers, customers and union contacts benefit the Corporation in all aspects of operations. Mr. Matthews assumed interim leadership over the Tubular segment, as well, following Mr. Rintoul's retirement in February 2018.

Scott Buckiso – Mr. Buckiso led the European Solutions commercial entity, which is comprised of our Slovakian operations, supplying Automotive, Appliance, Electrical, Packaging and Construction products throughout Europe. Through his superior leadership, the European segment delivered over $400 million EBITDA in 2017, a 52% improvement from 2016. After several unfortunate contractor safety incidents, he prioritized contractor safety performance, implemented dramatic changes to the safety program (including contractor safety procedures), and saw new safety records achieved for both OSHA recordable rate and consecutives days without an OSHA recordable case for both USSK personnel and contractors. Mr. Buckiso's team also achieved production records across nearly every line, and delivered exceptional quality performance for their customers. Mr. Buckiso provided superior leadership regarding environmental sustainability, reducing CO2 emissions and increasing recycling projects and commercial activity across our European operations. Mr. Buckiso's industry knowledge and focused leadership continues to solidify the segment as a strong performer for the Corporation.

David Rintoul – Mr. Rintoul provided leadership of the Tubular segment in 2017, as the business segment began to recover from an oil & gas industry downturn and realized substantial EBITDA improvement over 2016. Under Mr. Rintoul's leadership, the Tubular group achieved a 25% improvement in OSHA recordable performance and had strong environmental performance. Mr. Rintoul also oversaw improvements in production quality and cost. He led the group's international expansion, as customers were serviced in the Middle East and South Pacific. Mr. Rintoul also further supported his customers by overseeing the development of innovative products for complex drilling. Mr. Rintoul's strong leadership, particularly during challenging times, positioned the segment for recovery and strengthened long-term partnerships in the industry. Mr. Rintoul retired from the Corporation as of February 28, 2018.

Mario Longhi – Mr. Longhi provided leadership of the Corporation's transformation efforts through ongoing implementation and application of the Carnegie Way method as the disciplined and structured approach for improving business performance. He also served as a zealous advocate for the Corporation and the industry in Washington D.C. Mr. Longhi retired in June 2017.

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 2017,2020, the three-year performance period began on January 1, 2017,2020, and will end on December 31, 20192022 (the "2017“2020 Performance Period"Period”). The value of the performance awards granted underfor the 20172020 Performance Period was divided equally between relative TSR performance awards (which are equity-based) and ROCE performance awards. The TSR performance awards (which are cash-based). The three-year goals focus management on driving attractive returns onwere granted in equity, and the capital we employ and on increasing stockholder value.

ROCE performance awards were granted in cash, rather than equity, in order to preserve shares in the plan.

TSR Performance Awards — How We Determine Payouts

For awards granted beginning in 2019, 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 (see the “Performance Peer Group”), over the three-year performance 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 shareas well as for each year within the performance period, divided byperiod.

Interpolation is used to determine actual awards between the threshold, target, and maximum levels. TSR performance is calculated over a three-year performance period as described in Appendix B of this proxy statement.

In order to address any potential pay for performance disconnect should the Corporation'sCorporation’s TSR be negative over the three-year performance period (regardless of relative performance) payouts may beare capped as follows:


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


Payout is capped at threshold50% of target if the Corporation'sCorporation’s TSR is between -5% to -10% on a CAGR basis; and


Payout is forfeited if the Corporation'sCorporation’s TSR is lower than -10% on a CAGR basis.

The negative cap policy is effective for grants made in 2016 and later.

ROCE Performance Awards — How We Determine Payouts

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 ROCE awards payout at 50% at the threshold level, 100% at

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.

Compensation Discussion and Analysis

Restricted Stock Units (20%(40% of LTIP Award Value)

Restricted stock units (RSUs) are awards that deliver shares of common stock and accumulated dividends upon vesting. RSUs 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 Compensation Committee believes that RSUs provide the best retention benefits among our long-term incentives, especially during times of challenging economic and industry conditions. Since the value of the RSUs is variable based upon our stock price, this element of executive compensation is aligned with our stockholders’ interests. 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" awards that reward executives for an increase in the Corporation'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'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

generally subject to continued employment on each vesting date.

On 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 $39.265.

Other Awards

Mr. Bradley received a one-time cash award of $125,000 as part of his new-hire incentive. In 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. Soni received a cash award of $30,000, which was the second-installment of a new hire incentive.

Changes to the 2018 Compensation ProgramBenefits & Retirement Programs

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 AICP metric.

Changed Weighting of AICP Metrics: The Committee rebalanced the weighting of the 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

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.

Retirement Programs

We provide the retirement benefits described below in order to attract and retain talented executive officers.executives. 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"“Pension Plan”), which is a defined benefit plan; and


United States Steel Corporation Savings Fund Plan for Salaried Employees (the "Savings Plan"“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. Messrs. Matthews andMr. Buckiso wereis the only NEOsNEO covered by the Pension Plan and the Non 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" 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 2017,2020, 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“Supplemental Thrift Program"Program”);


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


United States Steel Corporation Supplemental Retirement Account Program (the "Supplemental“Supplemental Retirement Account Program"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 benefitsmatching contributions and Retirement Account contributions that are not permitted to be provided under the Qualified PlansSavings Plan 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-termannual incentive compensation plans, which is excluded under the Qualified Plans.Savings Plan. 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

To support our retention objectives, 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) employment:

COMPENSATION DISCUSSION AND ANALYSISCOMPENSATION POLICIES AND OTHER CONSIDERATIONS
Clawback Policy
The Board has adopted a policy detailing procedures to recover payment of any compensation (cash or equity) if an executive engaged in any fraud or misconduct, including gross negligence, that resulted in the need for a material restatement of the Corporation’s publicly filed financial results. For any periods during which a performance-based award was paid or credited to the executive, such award will be subject to reduction, cancellation, or reimbursement to the Corporation at the Board’s discretion. This policy is stated in our Corporate Governance Principles which are available on our website www.ussteel.com.
Change in Control Arrangements

The Corporation's Change in Control Severance Plan (the "CIC Plan"“CIC Plan”) generally provides for the payment of severance benefits to certain eligible executives, including each of the named executive officers,NEOs, in the event their employment with the Corporation terminates involuntarily following a change in control of the Corporation.

The CIC Plan enables our executives to evaluate corporate transactional opportunities that may be in the best interests of the Corporation'sour 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 officerNEO 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 NEOs are entitled to a payment equivalent to a multiple of his or her salary and .annualannual incentive awardaward. For Messrs.Mr. Burritt, and Bradley, the severance payment multiple is 2.5x, and for Ms. Breves and Messrs. Matthews, Rintoul,Bruno, Buckiso and Holloway, is 2x and for Mr. Soni is 1x. Neither Mr. Longhi nor Ms. Folsom are entitled to a change in control severance payment following termination of employment with the Corporation.2x. We do not

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

Employment Letter Agreements

In general, the Corporation doeswe do not enter into long-term employment agreements with itsour executives but may enter into agreements for a limited period of time to attract or retain experienced professionals for high level positions. Under 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 ofWe entered into a letter agreement with Mr. Buckiso which expires on November 20, 2018,in July 2020 providing Mr. Buckiso may become entitled to a payment of up to threewith certain pension make-whole, retention and a half timesother payments in consideration for 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 agreementcontinued employment with the Corporation providingbeyond the date on which he was eligible 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 employed for at least six months afteran immediate retirement under 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 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

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' compensation. The use of an independent consultant provides additional assurance that the Corporation's executive compensation programs are reasonable and consistent with the Corporation'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 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,Pension Plan and the reasonableness of individual compensation awards.

With respect to the CEO's compensation, the Committee makes its determinations based upon its evaluation of the CEO's performance and with input from its consultant. Each year, the Committee reviews with the Board of Directors the CEO's goals and objectives, and the evaluation of the CEO's performance with respect to the prior year's goals and objectives. The CEO does not participate in the

Compensation Discussion and Analysis

presentations to, or discussions with, the Committee in connection with the setting of his compensation.

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.

Peer Groups

The Committee also considers relevant market pay practices in its decision making process. The Committee uses the peer group data below as a frame of reference to guide executive compensation decisions. The Corporation utilizes two peer groups as described below:

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 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.

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 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.

The 2017 Performance Peer Group consists of the following companies:

        AK Steel Holding Corporation

        Allegheny Technologies Inc.

        Carpenter Technology Corporation

        Cliffs Natural Resources Inc.

        Commercial Metals Company

        Nucor Corporation

        Olympic Steel Inc.

        Reliance Steel & Aluminum Co.

        Schnitzer Steel Industries, Inc.

        Steel Dynamics Inc.

        TimkenSteel Corporation

        Worthington Industries, Inc.

No changes were made to the Performance Peer Group for 2018.

Compensation Policies and Other Considerations

Stock Ownership and Holding Guidelines

We have comprehensive stock ownership and holding guidelines designed to align the interests of our executive officers with those of the Corporation's stockholders.

The table below does not include Messrs. Longhi and Rintoul or Ms. Folsom, who were not employed with the Corporation as of the date of filing.

Under our stock ownership guidelines, Mr. Burritt has a stock ownership requirement of 6x his salary midpoint. Messrs. Bradley, Matthews, and Buckiso each have a stock ownership requirement of 3x their salary midpoint; and Mr. Soni has an ownership requirement of 1x his salary midpoint. The stock ownership guidelines require that an executive must retain 100% of the after-tax value of stock acquired upon the vesting of restricted stock units and performance awards and 100% of the after-tax value of shares issued upon the exercise of stock options until the ownership requirement is satisfied. All of the NEOs are in compliance with the terms of the policy.

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'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'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'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.

For these reasons, the Committee concluded that our 2017 compensation and organization policies and practices are

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 Compensation 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 Compensation 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 Compensation 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, 2017 filed with the SEC on February 21, 2018.

(10)
This column represents the full grant date fair market value forof the equity incentive awards, stock awards and optionequity-based LTIP awards, calculated in accordance with ASC 718 based on the average of the high and low stock priceprices on the date of the grant. The restricted stock units accrue dividends at a non-preferential rate ($0.05)0.01) per share (as of the last announced dividend) thatand are paid when the underlying restricted stock units vest.are distributed. 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, 201725, 2020 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%92.9224% 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.

COMPENSATION DISCUSSION AND ANALYSISU. S. STEEL PENSION PLAN

U. S. Steel Pension Plan

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, and SoniMr. Buckiso is the only NEO who were hired in 2013, 2017, 2007, 2012 and 2016 respectively, and Ms. Folsom, who was hired in 2014, are not participantsis a participant in the U. S. Steel Pension Plan and the related nonqualified plans. Mr. Matthews and Mr. Buckiso are participants under the U. S.United States Steel Corporation Non Tax-Qualified Pension Plan and the related non-qualified plans as noted under "Pension Plan Compensation" on page 55.(“Non Tax-Qualified Pension Plan”). Benefits under the U. S. Steel Pension Plan and the related non-qualified plans described belowNon Tax-Qualified Pension Plan 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 whichthat is determined from the 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 toBecause Mr. Buckiso has over 30 years of credited service and earnings while employed by the Corporation, service and earnings for certaineligibility purposes, include those accrued while workinghe is eligible for certain affiliated companies.

an unreduced Final Earnings Benefit.

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. 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, 2017,2020, Mr. Matthews'Buckiso’s annual Career Earnings Benefits would have been reduced by 53.33%, and if Mr. Buckiso had retired on December 31, 2017, his annual Career Earnings Benefits would have been reduced by 58.88%48.82%.

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.

Assumptions used in the calculationsPlan include an unreduced benefit age of 62, the election of a lump sum option and credited service, and career earnings and final average earnings as of December 31, 2015. Final average earnings isare based on the average of the monthly salaries paid in the highest five

consecutive 12 month12-month period during the ten years preceding December 31, 2015.

The salary amounts include base salary, excluding incentive compensation. The number of years of credited service in the 2017 Pension Benefits table shows the number of years earned and used to calculate the accrued benefits reported.

NON TAX-QUALIFIED PENSION PLAN

Non Tax-Qualified Pension Plan

The purpose of the United States Steel Corporation Non Tax-Qualified Pension Plan ("Non Tax-Qualified Pension Plan") is to compensate individuals for the loss of benefits under the U. S. Steel Pension Plan that occur due to certain limits established 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.

COMPENSATION DISCUSSION AND ANALYSISNON-QUALIFIED DEFERRED COMPENSATION

Supplemental Pension Program

NON-QUALIFIED DEFERRED COMPENSATION

The purpose of the United States Steel Corporation Executive Management Supplemental Pension Program (the "Supplemental Pension 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. 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'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 short-term incentive payments were the highest out of the last ten consecutive calendar years prior to the executive's termination. Benefits are paid as an actuarially determined lump sum.

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 made 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 $270,000limited to $285,000 in 2017)2020) and combined Corporation and individual

annual contributions (which limit was $54,000were limited to $57,000 in 2017)2020). 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's eligibleexecutive’s base salary.

Executive Compensation Tables

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

consent of the Corporation, or because of death, subject to the six-month waiting period under Section 409A of the Code for specified employees.

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 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 –(ColumnVoluntary 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'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 hisplan or, her successor.

With respect to long-term incentives, the Compensation & Organization Committee (the "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, ten months worked during the twelve-month vesting period from March 2017 to February 2018 would result in a vesting of ten-twelfths of the number of shares scheduled to vest in February 2018, with no such pro rata vesting for the shares scheduled to vest after February 2018). Given our assumption under this scenario that the Committee has consented to the executive's retirement, the pro rata vesting discussed above has been applied to the calculations in the 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 eligible for retirement, a participant involuntary termination of employment with the Supplemental Pension Program.

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 of employment, and benefits would be paid according to the terms of each benefit plan's provisions following the termination of an executive's employment in connection with a change in control.plan. The following discussion describes the events and circumstances that would trigger payments under the CIC Plan.


70UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
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).

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;Severance;


Supplemental Retirement Benefit;


Welfare Benefits;


Outplacement services; and


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 Reason"Reason” 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'sexecutive’s current work location;

Failure to continue all of the Corporation'sCorporation’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'sexecutive’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 Control"Control” 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 "Potential“Potential Change in Control"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'sCorporation’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;

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.


UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT71

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
An"Applicable Event"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 (Columns E and F)

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 or becomes totally and permanently disabled 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.

was fully vested.

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, 20172020 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;

2020.
2.

The stock price used for valuation purposes for the long-term incentive awards was the closing stock price on December 29, 2017,31, 2020, which was $35.19;$16.77.
3.

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'sCorporation’s experience, made gender neutral on a nine to one male/female ratio; andratio.
4.

4.
The December 31, 20172020 Pension Benefit Guaranty Corporation interest rate of 0.75%0.00% was used to determine 20172020 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.

Potential Payments Upon Termination or Change2020, except for Mr. Burritt and Ms. Breves who are fully vested in Control
    In the event of a Change in Control, 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 Change in Control before the third anniversary date of the grant, in which the award will be immediately vested and released.

    In the event of disability or death, the awards are immediately vested and distributed based on the following rules:

    Death or Disability prior to the end of the first year of the Performance Period – 0% vested

    Death or Disability at or after the end of the first year of the Performance Period but prior to the end of the second year of the Performance Period – 50% vested

    Death or Disability at or after the end of the second year of the Performance Period – 100% vested

Mr. Buckiso did not receive Performance Awards in 2015. The vesting outcomes described in footnote 5 reflect his 2016 and 2017 grants ofunearned performance awards. Messrs. Bradley and Soni did not receive Performance Awards in 2015 or 2016. The vesting outcomes described in footnote 5 reflect their 2017 performance awards.

(7)
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's related non tax-qualified plans if his 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.

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 2.5x for Messrs.Mr. Burritt, and Bradley, 2x for Ms. Breves and Messrs. Bruno, Buckiso Matthews and Rintoul, and 1x for Mr. SoniHolloway the sum of  (a) base salary and (b) the current target under the short-termannual 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 Unemployment BenefitsBenefit Program and the Change in Control ProgramSeverance Plan 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

Short-Term Incentive

Following a voluntary termination with the Committee'sCompensation Committee’s consent or a retirement (Column A), ainvoluntary termination not for cause (Column C), 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 Compensation 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 5five years of service, or attainment of age 65.

If an executive'sexecutive’s employment terminates voluntarily without the Committee'sCompensation Committee’s consent or involuntarily (Columns B and C)B), 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).

Restricted Stock Units

Stock Options

Following a voluntary termination withUnder the Committee's consent or a retirement (Column A)terms of our long-term incentive program (“LTIP”), and subject to the Committee's discretion, (i) a prorated numberrestricted stock units are fully vested upon attainment of an executive's unvested stock options granted in 2015 and 2016 would vest based on the number of complete months worked during the vesting period and (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 executive is employed for at least six months following the date of grant (“Normal Retirement”) and is notvest on a participant in the

Potential Payments Upon Termination or Change in ControlUNITED STATES STEEL CORPORATION

2021 PROXY STATEMENT

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Upon a voluntary termination with consent or retirement (Column A), pro rata vesting has been applied to the restricted stock units for all NEOs, except for Mr. Burritt and Ms. Breves who have met the requirements for a Normal Retirement and are fully vested in their restricted stock units.
If an executive'sexecutive’s employment terminates voluntarily without the Committee's consent or involuntarily for cause (Column B), all remaining unvested options are forfeited.

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

Stock options include a "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's consent or a retirement (Column A), and subject to the Committee's discretion, (i) a prorated number of an executive's unvested restricted stock units granted in 2015 and 2016 would vest based on the number of complete months worked during the vesting period and (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 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.

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

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.

In the event of disability (Column E) or death (Column F), all unvested restricted stock units vest immediately.

Performance Awards

FollowingUnder the terms of the LTIP performance awards are fully vested upon Normal Retirement and vest on a pro rata basis as described below upon Early Retirement. If an executive is not eligible for retirement, the Compensation Committee reserves the right to decide these matters on a case-by-case basis, but its practice has been to prorate the vesting of the performance awards as described above. As of December 31, 2020, Mr. Burritt and Ms. Breves have met the requirements for a Normal Retirement, Mr. Buckiso has met the requirements for an Early Retirement, and Messrs. Bruno and Holloway were not eligible to retire under the LTIP.

Upon a voluntary termination with the Committee's consent or a retirement (Column A), and provided that the relevant performance goals are achieved, (i) the prorated value ofpro rata vesting has been applied to the performance awards grantedfor all NEOs, except for Mr. Burritt and Ms. Breves who have met the requirements for a Normal Retirement and are fully vested in 2015their performance awards.
If an executive’s employment terminates voluntarily without the Compensation Committee’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, 2020 and 2016 would vestthat 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 (eachwould 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.

For performance awards for which the performance goals are achieved, a modified proration is used in the event of adisability (Column E) or 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's employment terminates voluntarily without the Committee'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, 2017 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

We are committed to a compensation program that is internally equitable to motivate our employees to advance the strategy of the 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.

Because 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 Summary Compensation Table on page 40 of this proxy statement because he served as CEO for only for a portion of the year, and, consequently, actually earned a lower salary and lower compensation under the AICP and LTIP while he served as our Chief Financial Officer and Chief Operating Officer.

We calculated each employee'semployee’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, 20172020 (the "Determination Date"“Determination Date”). Pay to identify our Median Employee. The following pay elements that were included in determining the annual total cash compensation for each employee are:

Salary,employee:


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


annual incentive payment received for performance in fiscal year 20162020 (for non-represented employees);


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

Quarterly profit sharing payments (for represented employees only); and
Other

other cash payments (including payments related to shift differential, holidays and vacations) (for represented employees only).

Our calculation includes all full-time, part-time, temporary and seasonal employees of the Corporation and its consolidated subsidiaries employed as of October 1, 20172020 (other than the CEO). Also, included inExcluded from the data were 129 leased employees employed by third parties for whom we determined thewere unable to determine compensation. All of our thirteenseven employees located in the Czech Republic, France Germany, United Arab Emirates, Canada and Italy,Germany, 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.4 employees from Germany. Our total U.S. employee and non-U.S. employee population (including leased employees), duringas of the twelve-month period ended October 1, 2017,Determination Date 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.

22,511.

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

We 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"“Median Employee”).

Proposal 3: Ratification of the Appointment of PricewaterhouseCoopers LLP as Independent Registered Public Accounting Firm

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

Pursuant toUnder 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, then 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'sPwC’s knowledge of U. S. Steel'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 utilizingself-assessment. Additionally, for the Center forwork performed on the 2020 audit, the Audit Quality, External Auditor Assessment Tool.Committee discussed and evaluated PricewaterhouseCoopers’ performance, which included an evaluation by the Corporation’s management of PricewaterhouseCoopers’ performance. 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 2017,2020, PwC performed professional services for U. S. Steel in connection with audits of the financial statements of U. S. Steel, and of U. S.

In addition to increasing the number of shares available for grant, the amended and restated Plan eliminates certain provisions that are no longer needed following the repeal of Section 162(m) of the Internal Revenue Code (the “Code”), as well as clarifies the Compensation Committee’s ability to modify performance-based cash awards.

WHY YOU SHOULD VOTE TO APPROVE THIS PLAN

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. Having an adequate number of shares available for issuance under the Plan is an important factor in fulfilling these purposes.

The Plan currently authorizes the issuance of 18,200,000 shares of common stock and, as of March 1, 2021, had approximately 1,774,681 shares available for issuance. The Compensation Committee expects that if the stockholders approve the amended and restated Plan, then the number of shares available under the Plan will be sufficient for approximately three years based on current expected equity grant practices.
What happens if the Plan is not approved by our stockholders?
If the amended and restated Plan is not approved by our stockholders, then the Plan will continue in effect in its present form and we will continue to grant equity awards under the current terms of the Plan until the shares remaining available for issuance are exhausted, which the Compensation Committee estimates will occur in 2022 based on current expected equity grant practices. Failure of our stockholders to approve the amended and restated Plan also will not affect the rights of existing award holders under the Plan or under any previously granted awards under the Plan.
No material changes to the Plan have been made since the Plan was last approved by stockholders.

BACKGROUND
Prior to adoption of the Plan in 2016, the Corporation issued awards under the 2005 Stock Incentive Plan (the “2005 Plan”). The 2016 Plan replaced the 2005 Plan, and no new awards may be issued under the 2005 Plan. Any outstanding awards under the 2005 Plan granted before the approval of the 2016 Plan remain outstanding according to their terms.
The 2016 Plan, as adopted by the Board and approved by the stockholders, initially authorized the issuance of 7,200,000 shares of common stock for equity awards granted after the date of the 2016 Annual Meeting. In 2017, the stockholders approved an amendment to the Plan to increase the number of shares available for issuance by 6,300,000 shares, and in 2020 stockholders approved an amendment to the Plan to increase the number of shares available for issuance by 4,700,000 for a total of 18,200,000 shares.
In determining the number of additional shares of common stock to be requested under the amended and restated Plan, the Compensation 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 Compensation 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.
Burn Rate
The burn rate is the total equity awards granted under the Plan in a fiscal year divided by the weighted average common stock outstanding in the year indicated. The three-year average burn rate is 1.12% as shown in the table below, which is generally in-line with many institutional expectations and certain proxy advisory firms.

In fiscal 2018, 2019 and 2020, the performance awards earned total 150,133 shares, 384,664 shares and 0 shares, respectively.
Overhang
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 plan; and

C is the total outstanding shares of common stock.

2021 PROXY STATEMENT

Proposal 4:SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
As of December 31, 2020, the Corporation had 2,046,236 outstanding stock options with a weighted average remaining term of 3.72 years, and a weighted average exercise price of  $25.98. As of that date, the Corporation had 5,101,025 outstanding full-value awards, 6,092,033 shares available for future grant under the 2016 Plan, and 220,432,458 outstanding shares of common stock. This results in an overhang of 5.67%. Taking into account the proposed shares to be authorized under the Plan and the outstanding shares of common stock as of March 1, 2021, the overhang increases to 9.35%.
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 Compensation Committee with respect to equity awards is set forth in the “Long-Term Incentive Program” section and elsewhere in the Compensation Discussion and Analysis section of this proxy statement.
SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
The following is a summary of the main features of the Plan, as amended and restated. This summary is qualified in its entirety by the specific terms of the amended Plan, which is attached as Appendix C.
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, 2020, the Corporation had approximately 325 employees and 13 non-employee directors eligible to receive awards under the Plan. The Compensation Committee generally does not consider other service providers to be eligible to receive awards under the Plan and has not granted awards to any other service providers in the past and does not presently intend to do so.
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 18,200,000 shares, subject to proportionate adjustment in the event of stock splits and similar events. If approved by the stockholders, the amended and restated Plan would increase the maximum number of shares that may be issued under the Plan to 32,700,000 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 1.78 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 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.

82UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

Proposal 4:SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
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 each qualify as 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 Compensation 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 Compensation 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 Compensation Committee pursuant to the terms of the Plan are final, conclusive and binding on all persons, including the Corporation, its subsidiaries and participants.
The Compensation 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 Compensation Committee may also delegate to one or more officers of the Corporation the authority to grant awards to participants who are not directors or officers (as defined under Section 16 of the Exchange Act), subject to limitations established by the Compensation 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 Compensation 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 Compensation 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 Compensation 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, subject only to the restrictions imposed by the Compensation Committee, including limitations on the right to vote restricted stock. Dividends and dividend equivalents may accrue on restricted stock, but may not be paid before satisfaction of the restrictions.
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 Compensation 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 of one or more performance goals established by the Compensation Committee at the time of the award during a specified performance period.
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 Compensation Committee at the time of grant, and may be paid in cash or shares.
The Compensation 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

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT83

Proposal 4:SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
based on the achievement of the performance goals and such other terms and conditions applicable to the award as the Compensation Committee may, in its discretion, determine. The Compensation Committee may retain the discretion to reduce (but not to increase) the amount of a performance share 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 these performance measures may be based either on the performance of:

the participant, the Corporation, a subsidiary or subsidiaries, affiliate or affiliates, 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 Compensation Committee at the time of making a performance award.
The Compensation Committee may in its discretion also determine to use other objective performance measures as performance goals. The Compensation 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 Compensation Committee may grant to eligible employees, in lieu of salary or cash bonus, 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 Compensation Committee in its discretion may determine.
The Compensation Committee may, in its discretion, also use other stock-based awards in connection with, or to satisfy obligations of the Corporation or a subsidiary or an affiliate under, other compensation or incentive plans, programs or arrangements of the Corporation or any subsidiary or affiliate for eligible participants, including the Deferred Compensation Program for Non-Employee Directors and the Non-Employee Director Stock Program. The Compensation 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
Awards may not be granted in any calendar year to any participant in excess of the following aggregate limits, subject to these 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 subject to performance goals, 1,000,000 shares (this limit applies separately to each type of 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 Compensation Committee.

84UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

Proposal 4:SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
Vesting
All awards granted under the Plan will vest based upon employment or service for a period of at least twelve (12) months from the date on which the award is granted and there is no acceleration of vesting to be more rapid than vesting after twelve (12) months. However, the Compensation Committee has discretion to provide for accelerated vesting or exercisability in the terms of an award or otherwise in connection with death, disability, retirement, involuntary termination of employment or service without cause or a change in control. 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.
Repricing and Reload Options Prohibited
The Compensation Committee may not, without stockholder approval

amend or modify the terms of any outstanding option or appreciation right to reduce the exercise price or

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 Compensation Committee, if a change in control occurs and within two years thereafter a participant’s employment is terminated either:

involuntarily for any reason other than cause; or

voluntarily for good reason in the case of a member of executive management);
then all outstanding stock options, and other awards will become fully exercisable and remain exercisable until the expiration date of the award.
Also, all restrictions or limitations, including risks of forfeiture and deferrals, on awards subject to restrictions or limitations under the Plan will lapse.
All performance goals applicable to performance awards will be measured over the shortened performance period ending on the date of the change in control. Unless otherwise determined by the Compensation 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.
Recoupment Policy
The Compensation 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. 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’s publicly filed financial results.
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.
No Material Changes to Plan Without Stockholder Approval
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.

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. Subject to the limitations of Section 162(m) of the Code, the Corporation will be entitled to a deduction in the same amount and generally at the same time as the participant recognizes ordinary income.
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. Subject to the limitations of Section 162(m) of the Code, the Corporation will be entitled to a deduction in the same amount and generally at the same time as the participant recognizes 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 excess (if any) of the then-fair market value of the shares determined without regard to the restrictions over 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 excess, if any, of the then-fair market value of the shares over the amount, if any, paid for the shares. Subject to the limitations of Section 162(m) of the Code, the Corporation will be entitled to a deduction in the same amount and generally at the same time as the participant recognizes ordinary income.
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.

86UNITED STATES STEEL CORPORATION2021 PROXY STATEMENT

Proposal 4:SUMMARY OF THE 2016 OMNIBUS INCENTIVE COMPENSATION PLAN, AS AMENDED AND RESTATED
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. Subject to the limitations of Section 162(m) of the Code, the Corporation will be entitled to a deduction in the same amount and generally at the same time as the participant recognizes ordinary income.
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 a 20% federal excise tax (in addition to federal income tax) to the participant.

The numbers in columns (1) and (2) of this row contemplate all shares that could potentially be issued as a result of outstanding grants under the 2005 Stock Incentive Plan and the 2016 Omnibus Incentive Compensation Plan as of December 31, 2020. For more information, see our Annual Report on Form 10-K for the year ended December 31, 2020, Note 15 to the Consolidated Financial Statements.

The calculation in column (2) does not include the Common Stock Units since the weighted average exercise price for Common Stock Units is one for one; that is, one share of common stock will be given in exchange for each unit of such phantom stock accumulated through the date of the director’s retirement. Also, the calculation in column (2) does not include the performance awards since the shares issued for performance awards can range from zero for one to two for one; that is, performance awards may result in up to 3,170,600 of common stock being issued (two for one), or some lesser number of shares (including zero shares of common stock issued), depending upon the Corporation’s common stock performance versus that of a peer group of companies or the Corporation’s return on capital employed performance over a performance period.

DELINQUENT SECTION 16(A) REPORTS
DELINQUENT SECTION 16(A) REPORTS
Under Section 16(a) of the Securities Exchange Act of 1934, our directors and executive officers and persons holding more than 10% 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 our review of reports filed with the SEC and other information furnished to us, there were no late filings or failures to file 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.
CERTAIN LEGAL MATTERS
On October 2, 2017, an Amended Shareholder Class Action Complaint was filed in the United States District Court for the Western District of Pennsylvania consolidating previously-filed actions. Separately, five related shareholder derivative lawsuits were filed in State and Federal courts in Pittsburgh, Pennsylvania and the Delaware Court of Chancery. The underlying consolidated class action lawsuit alleges that U. S. Steel, 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 of the Corporation’s common stock (collectively, Defendants) 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 from January 27, 2016 to 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 current and former members of the Board of Directors failed to exercise appropriate control and oversight over the Corporation and were unjustly compensated. The plaintiffs seek to recover losses that were allegedly sustained. The class action Defendants moved to dismiss plaintiffs’ claims. On September 29, 2018 the Court ruled on those motions granting them in part and denying them in part. On March 18, 2019, the plaintiffs withdrew the claims against the Defendants related to the 2016 secondary offering. As a result, the underwriters are no longer parties to the case. The Corporation and the individual defendants are vigorously defending the remaining claims. On December 31, 2019, the Court granted Plaintiffs’ motion to certify the proceeding as a class action. The Corporation’s appeal of that decision has been denied by the Third Circuit Court of Appeals and the class has been notified. Discovery is proceeding.

We present adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA to enhance the understanding of our ongoing operating performance and established trends affecting our core operations, 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, and significant temporary idling charges,events that can obscure underlying trends. U. S. Steel'sSteel’s management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA as an alternative measuremeasures of operating performance and not an alternative measuremeasures of the Company'sCorporation’s liquidity.

U. S. Steel'sSteel’s management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA useful to investors by facilitating a comparison of our operating performance to the operating performance of our competitors. Additionally, the presentation of adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA provides insight into management'smanagement’s view and assessment of the Company'sCorporation’s ongoing operating performance, because management does not consider the adjusting items when evaluating the Company'sCorporation’s financial performance.
Adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA should not be considered a substitute for net earnings (loss), earnings (loss) per diluted share or other financial measures as computed in accordance with U.S. GAAP and is not necessarily comparable to similarly titled measures used by other companies.

Any action of the Committee with respect to the Plan shall be final, conclusive and binding on all persons, including the Corporation, Subsidiaries, Affiliates, Participants, any person claiming any rights under the Plan from or through any Participants, employees, directors and stockholders. The express grant of any specific power to the Committee, and the taking of any action by the Committee, shall not be construed as limiting any power or authority of the Committee. Each member of the Committee shall be entitled to, in good faith, rely or act upon any report or other information furnished to him by an officer, manager or other employee of the Corporation or a Subsidiary, the Corporation’s independent certified public accountants, or any executive compensation consultant or other professional retained by the Corporation and/or Committee to assist in the administration of the Plan.

UNITED STATES STEEL CORPORATION2021 PROXY STATEMENTC-5

APPENDIX C
SECTION 4. SHARES SUBJECT TO THE PLAN
4.01
The maximum number of Shares which may be issued and in respect of which Awards may be granted under the Plan shall be limited to 32,700,000 Shares, subject to adjustment as provided in Section 8.01, which may be used for all forms of Awards (such Shares may be referred to as “Available Shares”). Each Option or Appreciation Right shall reduce the number of Available Shares by one Share for each Share represented by such Option or Appreciation Right, except to the extent the Award is settled in cash. All other Shares to which an Award other than an Option or Appreciation Right relates shall be referred to as “Full-Value Shares” and, unless such Award is settled in cash, shall reduce the number of Available Shares by 1.78 Shares.
For purposes of this Section 4.01, the number of Shares to which an Award relates shall be counted against the number of Available Shares under the Plan at the time of grant of the Award, unless such number of Shares cannot be determined at that time, in which case the number of Shares actually distributed pursuant to the Award shall be counted against the number of Available Shares under the Plan at the time of distribution; provided, however, that Awards related to or retroactively added to, or granted in tandem with, substituted for or converted into, other Awards shall be counted or not counted against the number of Shares reserved and available under the Plan in accordance with procedures adopted by the Committee so as to ensure appropriate counting but avoid double counting.
If and to the extent any Award granted under this Plan or any award granted under the 2005 Stock Incentive Plan (“2005 Plan”) and outstanding on the Effective Date (a “2005 Plan Award”) is forfeited or otherwise terminates without payment being made to the Participant in the form 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 or 2005 Plan Award shall, to the extent of any such forfeiture or termination or alternative payment, again be available for Awards under the Plan. Subject to the provisions of Section 8.01, such Shares shall be added to the number of Available Shares at the rate for which the proxiesaward was originally subtracted from the number of Available Shares under this Plan or from the number of Shares that were available under the 2005 Plan, as applicable. If the exercise price of an Award is paid by delivering to the Corporation Shares previously owned by the Participant or by withholding Shares issuable upon exercise or if Shares are instructeddelivered or withheld for purposes of satisfying a tax withholding obligation or if Shares are repurchased by the Company with Option proceeds, the number of Shares covered by the Award equal to the number of Shares so delivered, withheld or repurchased shall be counted, however, against the number of Shares granted and shall not again be available for Awards under the Plan. In addition, all Shares covered by an Appreciation Right, to the extent that it is exercised and settled in Shares, shall be counted against the number of Shares granted and shall not again be available for Awards under the Plan. Any Shares distributed pursuant to an Award may consist, in whole or part, of authorized and unissued Shares or of treasury Shares, including Shares repurchased by the Corporation for purposes of the Plan.
SECTION 5.   ELIGIBILITY, VESTING REQUIREMENTS AND PROHIBITION ON REPRICING AND RELOAD OPTIONS
5.01
Eligibility. Awards may be granted only to individuals who are employees, other service providers and/or non-employee directors of the Corporation or any Subsidiary or Affiliate.
5.02
Vesting of Awards. All Awards shall provide for vesting based on employment or service which is at least twelve (12) months from the date on which such Award is granted, and there shall be no acceleration of vesting of an Award to be more rapid than vesting after twelve (12) months, except for the Committee’s discretion to provide for accelerated vesting or exercisability in the terms of an Award or otherwise in connection with death, disability, retirement, involuntary termination of employment or service without Cause or a Change in Control. Notwithstanding any contrary provision of the Plan, up to five percent (5%) of the aggregate number of Shares authorized for issuance under the Plan may be issued pursuant to Awards without regard to the limitations of this Section 5.02.
5.03
Repricing and Reload Options Prohibited. Except as provided in Section 8 (Adjustment Provisions), the Corporation may not, without obtaining stockholder approval: (a) amend or modify the terms of any outstanding Option or Appreciation Right to reduce the exercise price of such outstanding Option or Appreciation Right; (b) 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 (c) cancel, exchange or permit or accept the surrender of any outstanding Option or Appreciation Right in exchange for any other Award, cash or other securities for purposes of repricing such Option or Appreciation Right. No Option may be granted to any individual on account of the use of Shares by such individual to exercise a prior Option.

APPENDIX C
SECTION 6.   SPECIFIC TERMS OF AWARDS
6.01
General. Subject to the terms of the Plan and any applicable Award Agreement, Awards may be granted as set forth in this Section 6. In addition, the Committee may impose on any Award or the exercise thereof, at the date of grant or thereafter (subject to the terms of Section 10.01), such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine, including separate escrow provisions and terms requiring forfeiture of Awards in the event of termination of employment or service by the Participant. Except as required by applicable law, Awards may be granted for no consideration other than prior and/or future services. Dividends and dividend equivalents shall not be paid on Options, Appreciation Rights and unvested Full-Value Shares. 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.
6.02
Options. The Committee is authorized to grant Options to Participants, subject to the following terms and conditions:
(a)
Exercise Price. The exercise price per Share of an Option shall not be less than 100% of the Fair Market Value of a Share on the date of grant of such Option.
(b)
Option Term. The term of each Option shall be determined by the Committee, except that, consistent with the provisions of Section 7.04, no Option shall be exercisable after the expiration of ten years from the date of grant. The Option shall be evidenced by a form of written Award Agreement, and subject to the terms thereof.
(c)
Times and Methods of Exercise. The Committee shall determine the time or times at which an Option may be exercised in whole or in part, the methods by which the exercise price may be paid or deemed to be paid, and the form of such payment, including, without limitation, cash, Shares, or other property or any combination thereof, having a Fair Market Value on the date of exercise equal to the exercise price, provided, however, that in the case of a Participant who is at the time of exercise subject to Section 16 of the Exchange Act, any portion of the exercise price representing a fraction of a Share shall in any event be paid in cash or in property other than any equity security (as defined by the Exchange Act) of the Corporation.
Delivery of Shares in payment of the exercise price of an Option, if authorized by the Committee, may be accomplished through the effective transfer to the Corporation of Shares held by a broker or other agent. Unless otherwise determined by the Committee, the Corporation will also cooperate with any person exercising an Option who participates in a cashless exercise program of a broker or other agent under which all or part of the Shares received upon exercise of the Option are sold through the broker or other agent, for the purpose of paying the exercise price of an Option. Additionally, if authorized by the Committee, a Participant may elect the withholding of shares to be acquired upon exercise, valued at the Fair Market Value on the date of exercise, for the purpose of paying the exercise price of an Option. Notwithstanding any of the preceding, unless the Committee, in its discretion, shall otherwise determine, the exercise of the Option shall not be deemed to occur, and no Shares will be issued by the Corporation upon exercise of an Option, until the Corporation has received payment in full of the exercise price. Notwithstanding language in any grant form to the contrary, if the optionee is subject to taxation on the benefit received from the Option in a jurisdiction outside the United States the optionee (i) shall not be permitted to pay the exercise price by surrendering shares of Common Stock that he or she already owns or attesting to the ownership of shares of Common Stock and (ii) shall not be permitted to elect the withholding of shares to be acquired upon exercise to satisfy either the exercise price or the tax withholding obligation if, in the opinion of the Committee, such election could cause the participant, or the Corporation, to receive unfavorable tax treatment.
(d)
Termination of Employment. In the case of Participants who are employees or other service providers, unless otherwise determined by the Committee and reflected in the Award Agreement or award program:
(1)
if a Participant shall die while employed or engaged by the Corporation or a Subsidiary or Affiliate or during a period following termination of employment or engagement during which an Option otherwise remains exercisable under this Section 6.02(d), Options granted to the Participant, to the extent exercisable at the time of the Participant’s death, may be exercised within three years after the date of the Participant’s death, but not later than the expiration date of the Option, by the executor or administrator of the Participant’s estate or by the Person or Persons to whom the Participant shall have transferred such right by will or by the laws of descent and distribution;

Termination of Service. In the case of Participants who are non-employee directors, unless otherwise determined by the Board and reflected in the Award Agreement or award program:

(2)
if the service of a Participant with the Corporation and its Subsidiaries shall be terminated for reasons other than removal for Cause, Options granted to the Participant, to the extent exercisable at the date of the Participant’s termination of service, may be exercised within three years after the date of termination of service, but not later than the expiration date of the Option; and
(3)
except to the extent an Option remains exercisable under paragraph (1) or (2) above or under Section 9.01, any Option granted to a Participant shall terminate immediately upon the termination of all service of the Participant with the Corporation or a Subsidiary.

A Performance Award shall represent the right to receive Shares or a dollar amount based on the achievement, or the level of achievement, during a specified Performance Period of one or more Performance Goals established by the Committee at the time of the Award. Performance Goals may include threshold Corporation performance goals and Participant performance goals.
(c)
Terms of Performance Awards. At or prior to the time a Performance Award is granted, the Committee shall cause to be set forth in the Award Agreement or otherwise in writing (i) the Performance Goals applicable to the Award and the period during which achievement of the Performance Goals shall be measured (the “Performance Period”), (ii) the amount which may be earned by the Participant based on the achievement, or the level of achievement, of the Performance Goals or the formula by which such amount shall be determined and (iii) such other terms and conditions applicable to the Award as the Committee may, in its discretion, determine to include therein; provided, however, dividends and dividend equivalents may accrue, but shall not be paid with respect to Performance Awards before the Performance Goals are achieved and the Performance Awards are earned. The terms so established by the Committee shall be objective such that a third party having knowledge of the relevant facts could determine whether or not any Performance Goal has been achieved, or the extent of such achievement, and the amount, if any, which has been earned by the Participant based on such performance. 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; provided, however, that the exercise of such negative discretion shall not be permitted to result in any increase in the amount of any Performance Award payable to any other Participant.

Performance Goals based on such performance measures may be based either on the performance of the Participant, Corporation, a Subsidiary or Subsidiaries, an Affiliate or Affiliates, 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.
(e)
Committee Certification. Following completion of the applicable Performance Period, and prior to any payment of a Performance Award to the Participant, the Committee shall determine in accordance with the terms of the Performance Award and shall certify 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.

Performance Awards are not intended to provide for the deferral of compensation, such that Performance Awards shall be paid upon vesting and in no event later than the day which is two and one-half months following the end of the calendar year in which the Performance Period ends, or such other time period as may be required under Section 409A of the Code to avoid characterization of such Awards as deferred compensation.
(f)
Maximum Individual Performance Award Limit. No Participant shall be granted within any calendar year (i) Performance Shares which could result in such Participant receiving pursuant to such Performance Shares more than 1,000,000 Shares or the Fair Market Value thereof if paid in cash, or (ii) Performance Cash Awards which could result in such Participant receiving more than $20,000,000 in value.
(g)
Performance Award Pool. The Committee may establish a Performance Award pool, which shall be an unfunded pool, based upon the achievement of one or more Performance Goals during the Performance Period, as specified by the Committee. The amount of the Award Pool at the threshold, target and maximum performance levels may be a stated percentage of the Award Pool at the applicable level for the specified Performance Goals. The maximum amount payable to any Participant shall be stated in terms of a percentage of the award pool and the sum of such percentages shall not exceed 100%.

Any shares of Common Stock distributed with respect to any Restricted Stock held in escrow shall also be held by the Corporation in escrow and shall be subject to the same restrictions as are applicable to the Restricted Stock on which they were distributed.
If the outstanding shares of Common Stock shall be changed into or exchangeable for a different number or kind of shares of stock or other securities of the Corporation or another corporation, or cash or other property, whether through reorganization, reclassification, recapitalization, stock split-up, combination of shares, merger or consolidation, then equitable adjustments shall be made to the Awards, the Shares specified in Section 4.01 that may be issued under the Plan but which is not then subject to any outstanding Award, and the maximum number of Shares under Sections 6.02(f), 6.03(d), 6.04(d), 6.05(f).

In case of any adjustment or substitution as provided for in this Section 8.01, the aggregate option price for all Shares subject to each then outstanding Option, Restricted Stock Unit, Performance Award or Other Stock Based Award, prior to such adjustment or substitution shall be the aggregate option price for all shares of stock or other securities (including any fraction), cash or other property to which such Shares shall have been adjusted or which shall have been substituted for such Shares. Any new option price per share or other unit shall be carried to at least three decimal places with the last decimal place rounded upwards to the nearest whole number.
If the outstanding shares of the Common Stock shall be changed in value by reason of any spin-off, split-off or split-up, or dividend in partial liquidation, dividend in property other than cash, or extraordinary distribution to stockholders of the Common Stock, (i) the Committee shall make any adjustments to any then outstanding Option, Restricted Stock Unit, Performance Award or Other Stock Based Award, which it determines are equitably required to prevent dilution or enlargement of the rights of optionees and awardees which would otherwise result from any such transaction, and (ii) unless otherwise determined by the Committee in its discretion, any stock, securities, cash or other property distributed with respect to any Restricted Stock held in escrow or for which any Restricted Stock held in escrow shall be exchanged in any such transaction shall also be held by the Corporation in escrow and shall be subject to the same restrictions as are applicable to the Restricted Stock in respect of which such stock, securities, cash or other property was distributed or exchanged.
No adjustment or substitution provided for in this Section 8.01 shall require the Corporation to issue or sell a fraction of a Share or other security. Accordingly, all fractional Shares or other securities which result from any such adjustment or substitution shall be eliminated and not carried forward to any subsequent adjustment or substitution. Owners of Restricted Stock held in escrow shall be treated in the same manner as owners of Common Stock not held in escrow with respect to fractional Shares created by an adjustment or substitution of Shares, except that, unless otherwise determined by the Committee in its discretion, any cash or other property paid in lieu of a fractional Share shall be subject to restrictions similar to those applicable to the Restricted Stock exchanged therefore.
