LETTER TO OUR STOCKHOLDERS
FROM OUR CHAIRMAN OF THE BOARD AND OUR LEAD INDEPENDENT DIRECTOR
April 29, 2020
Dear Stockholder:
On behalf of our Board of Directors and management team, thank you for your continued support of Kaiser Aluminum. It is our pleasure to invite you to attend the Annual Meeting of Kaiser Aluminum Corporation to be held at the Company’s corporate office, located at 27422 Portola Parkway, Suite 200, Foothill Ranch, California 92610, on Wednesday, June 10, 2020, at 9:00 a.m., local time. While the Company does not expect to make a separate presentation, we expect our directors and officers to be present at the Annual Meeting and available to respond to any questions you may have.
As part of our contingency planning regarding novel coronavirus (“COVID-19”), we are preparing for the possibility that the date, time or location of the Annual Meeting may be changed or that the Annual Meeting may be held by means of remote communication (sometimes referred to as a "virtual" meeting). If we take this step, we will announce the decision to do so in advance through a press release and public filing with the Securities and Exchange Commission, and details will be available at www.kaiseraluminum.com.
Your vote is very important to us. Whether or not you plan to attend the Annual Meeting, we urge you to vote your shares as promptly as possible. Details of the business to be conducted at the Annual Meeting are included in this proxy statement, which we encourage you to read carefully. You may submit your voting instructions over the Internet or by telephone as indicated on the enclosed proxy card or by completing, signing and dating the enclosed proxy card and returning it by mail in the accompanying envelope. If you plan to attend the Annual Meeting, please review the information on attendance provided on in this proxy statement.
We would like to share with you several areas of particular significance in advance of our Annual Meeting and in connection with our distribution of this proxy statement:
CURRENT ENVIRONMENT AND BUSINESS STRATEGY
As we prepare the letter to stockholders this year, the COVID-19 pandemic has resulted in significant business and economic uncertainty, challenges and potential opportunities. We do not know how long the pandemic will last, what implications it will have on our business or what type of economic conditions we will experience as we look forward. However, we do know that for more than two decades, our business model, consistent strategy and core values have positioned us well for unexpected adversity, and we are prepared to address the challenges and potential opportunities presented by the pandemic. Our Board is closely overseeing the Company’s initiatives in responding to the COVID-19 pandemic and it continues to focus on the Company’s long-term goals and responsibilities.
The health and safety of our employees are and continue to be our first priority. Our facilities have continued to operate despite shelter-in-place mandates, reflecting their inclusion in the Critical Manufacturing Sector, as defined by the U.S. Department of Homeland Security, and recognition as essential businesses by state and local government authorities. We have implemented steps to protect our employees and limit visitors to our sites and, where possible, our employees are working remotely until we return to normal operations.
Over the past two decades, positioning Kaiser Aluminum as a preferred supplier has been a key tenet of our core values and our competitive strategy. Driven by this guiding principle we have developed strong and deep partnerships with our blue chip customer base, differentiating the Company with quality products and Best-in-Class customer satisfaction. This positions us well at all times, but especially during periods of economic distress when our customers turn to their most trusted and financially secure suppliers. Working in partnership to meet their needs in good times and in bad, we continue to strengthen and solidify these relationships.

Our business model is to be prepared at all times for unexpected economic adversity. We focus on managing for the downturn, and analyzing a number of recession case scenarios is integral to our planning, forecasting, capital investment and capital allocation processes. At every Board meeting, management and our Board review the Company’s liquidity under stress-tested conditions to ensure we can withstand a severe downturn in our served market segments.
In November 2019, we proactively completed two new debt financings. We replaced our previously existing secured revolving credit facility with a new $375 million facility that matures in 2024, and we retired $375 million aggregate principal amount of our 5.875% senior unsecured notes due 2024, issuing $500 million aggregate principal amount of 4.625% senior unsecured notes due 2028. In April 2020, we issued $300 million aggregate principal amount of 6.500% senior unsecured notes due 2025, increasing our total liquidity to approximately $1 billion, after adding net proceeds from the offering to the $688 million of liquidity as of March 31, 2020.
The great recession of 2008-2009 tested our business model. Unlike many other companies at the time, we validated our strategy and continued to focus on execution while tactically responding to changes in market conditions. With strong liquidity, we retained and paid our regular quarterly dividend and continued to proceed with a $100 million strategic capital investment in a state-of-the-art extrusion facility in Kalamazoo, Michigan, which today is a premium quality, low cost producer in its served market segments.
Although the ramifications and impact of the COVID-19 pandemic may be dramatically different than the economic disruption in 2008-2009, we are confident that our strong liquidity, our preferred supplier position and our track record for efficient execution of our strategy will enable us to address challenges and opportunities that come from this economic crisis.
We are providing an essential service to our customers and doing it in a way that reflects greatly on the proud history of Kaiser Aluminum. Working as a strong team, our managers are focused on the health and safety of our workforce, meeting our customers' needs, managing costs and ensuring we continue to adjust to fluid circumstances. Thank you to all the employees at Kaiser Aluminum for their dedication, loyalty and hard work.
2019 PERFORMANCE HIGHLIGHTS
Looking back, 2019 was a solid year as we achieved several financial milestones, including record value added revenue, adjusted EBITDA, adjusted net income and adjusted earnings per diluted share. We achieved these results despite planned and unplanned downtime at our Trentwood facility in Spokane, Washington in the first half of 2019, the impact of the General Motors strike in the second half of the year, and reduced sales and efficiency related to the significant number of automotive model changeovers in 2019.
In late 2019, we also finalized a new labor agreement that extends through 2025 for our two largest facilities in Spokane, Washington and Newark, Ohio, a testament to our relationship and partnership with the United Steel, Paper and Foresting, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO, CLC (the “USW”).
In addition, with continued confidence in the long-term outlook for our business, the Board approved a 12% increase in the quarterly dividend to $0.67 per share, up from the 9% increase in early 2019, marking the ninth consecutive year we have increased our quarterly dividend.
With a view towards the longer-term demand growth of heat treat plate for applications in our aerospace and general engineering end markets, we also announced a $375 million, multi-year expansion project at our Trentwood facility that will provide increased capacity, redundancy, efficiency and operational security for key bottleneck operations in the Trentwood facility's process flow. We will continue to monitor market conditions to determine the timing of the various modules contained within this strategic project including the initial $145 million investment in a new plate stretcher.
BOARD OVERSIGHT OF STRATEGY
Our Board remains actively focused on overseeing the Company’s business strategies, risk management, talent development, succession planning and development and execution of the Company’s long-term strategy. In addition to ongoing programs embedded within our enterprise risk management programs, additional areas of focus including environmental, social and governance matters, are reviewed by management with our Board throughout the year.
By focusing on our long-term outlook, we are best able to support our common goal of creating enduring value in our Company and for our stockholders. We contribute to management’s strategic plan by engaging the Company's senior

management in robust discussions about the Company’s overall strategy, priorities for its businesses, capital allocation, risk assessment and opportunities for continued long-term growth through our regularly scheduled meetings, including a dedicated annual strategic planning session, and throughout the year.
CORPORATE GOVERNANCE AND STOCKHOLDER ENGAGEMENT
We believe effective governance means ongoing and thoughtful evaluation of our governance structure, including our Board and Board committees, and constructive stockholder engagement on evolving environmental, social and governance issues. We conduct an annual corporate governance survey of management and non-management employees in order to monitor the internal perception around a broad range of topics including the Company's control environment, risk mitigation and management, the use of technology, Company values and the overall “tone at the top.”
Our Board values the feedback and insights gained from frequent engagement with our stockholders. In 2019, in addition to interactions regarding our financial performance, management engaged with stockholders representing approximately 60% of our outstanding shares on matters relating to our long-term business strategy and performance, corporate governance, executive compensation and corporate responsibility. We are committed to including our stockholders’ perspectives in boardroom discussions, and we believe that regular engagement with our stockholders is necessary in order to ensure thoughtful and informed consideration of those matters. We look forward to continuing to engage in productive dialogue with our stockholders in 2020 and beyond.
BOARD REFRESHMENT AND SUCCESSION PLANNING
Our Board recognizes the importance of and is committed to board refreshment and succession planning that ensures our directors possess a composite set of skills, experience and qualifications necessary to successfully review, challenge and help shape the Company’s strategic direction. We have a mandatory retirement policy that provides that unless otherwise approved by our Board, no individual may be nominated for election or re-election as a director if the individual would be age 75 or older at the time the term would begin. Our Nominating and Corporate Governance Committee also regularly evaluates the size and composition of our Board.
In 2018 and 2019, we added four new highly qualified independent directors, including Emily Liggett, Teresa M. Sebastian, Donald J. Stebbins, and Leo Gerard, to our Board. Ms. Liggett was President and Chief Executive Officer of Nova Torque, Inc. and has management and board experience in manufacturing, strategy, operations, product development, sales, marketing and business development. Ms. Sebastian is President and Chief Executive Officer of The Dominion Asset Group, was previously the Senior Vice President, General Counsel, Corporate Secretary and internal audit executive leader of Darden Restaurants, Inc., and is experienced in finance, mergers and acquisitions, global transactions, internal audit, governance, enterprise risk, and compliance. Mr. Stebbins is the former President and Chief Executive Officer of Superior Industries International, Inc. and has extensive automotive industry experience, as well as experience in international business, manufacturing, sales, product innovation and development, accounting and finance, and mergers and acquisitions. Mr. Gerard was the International President of the USW and has extensive labor and industry experience.
In addition, we have reduced our average Board tenure from 12.0 years at the 2018 meeting of stockholders to 8.8 years at the 2020 meeting of stockholders.
BOARD COMPOSITION
Our Board is highly independent, engaged and diverse in perspectives and backgrounds as reflected by its composition, which is currently 92% independent, 35% gender diverse and 17% ethnically diverse. This structure underscores the Board’s belief that the Company is best served when it can draw upon members with a variety of perspectives to exercise strong and experienced oversight. We have a policy of encouraging diversity of gender, ethnicity, age and background, as well as a range of tenures among our director nominees to ensure both continuity and fresh perspectives on our Board.
CORPORATE SUSTAINABILITY MATTERS
While the COVID-19 pandemic will have an impact on business conditions and our operations, our commitment to the sustainability of our business and creating long-term shareholder value for our stakeholders remains a critical and an integral part of our corporate values. We will continue to manage our business for long-term success in a manner that is economically, environmentally and socially responsible. Our interim 2019 Sustainability Report captures the highlights of our sustainability culture and initiatives that we continue to develop as good stewards of our environment and resources.

To all of our stakeholders - customers, suppliers, investors, employees and the communities in which we operate - your contribution and support have made Kaiser Aluminum what it is today - a highly differentiated, well-respected leader in our industry - and a company well positioned for the future. We look forward to continuing to deliver value to our customers, shareholders and communities. We are grateful for your support of Kaiser Aluminum and of our Board.

EXECUTIVE COMPENSATION HIGHLIGHTS
As noted in the letter from our Chairman and Lead Independent Director, our success over the years has been driven by our people, a highly focused and consistent strategy to drive steady continuous improvement and our pursuit of the following six key strategic initiatives that align our actions with our corporate values to ensure that our long-term success is driven by practices that are economically, environmentally and socially responsible:

Ÿ | Advance our position as the supplier of choice | Ÿ | Enhance quality and depth of technical and managerial talent
Ÿ | Achieve and sustain a position as a low cost producer | Ÿ | Sustain financial strength and flexibility
Ÿ | Pursue profitable sales growth | Ÿ | Enhance our standing as a valued corporate citizen

Each of these initiatives has been, and continues to be, reflected in our compensation structure. As described in further detail in the “Executive Compensation - Compensation Discussion and Analysis” section of this Proxy Statement, or CD&A, our 2019 compensation structure was developed and designed to:

• | align the interest of our named executive officers and stockholders by tying a significant portion of compensation to enhancing stockholder return;

• | attract, motivate and retain highly experienced executives with significant industry experience vital to our short-term and long-term success, profitability and growth;

• | deliver a mix of fixed and at-risk compensation with the portion of compensation at risk increasing with seniority;

• | tie our executive compensation to our ability to pay and safety, quality, delivery, cost and individual performance directly linked to our strategic initiatives; and

• | require increasing levels of financial performance as we continue to invest in our business.

In 2019, the compensation of our named executive officers consisted primarily of the following components:
iv

• | a base salary (1) compensating each named executive officer based on the level and scope of responsibility, individual expertise and prior experience and (2) providing a fixed amount of cash compensation upon which our named executive officers can rely;

• | a short-term annual cash incentive (1) payable only if our company achieved a certain adjusted earnings before interest, taxes, depreciation and amortization, or Adjusted EBITDA, performance level which has continued to increase annually, as we continue to invest in our business, resulting in increasingly demanding performance required to realize the same or similar payouts year-over-year, (2) adjusted based on our (a) safety performance, (b) quality performance, (c) delivery performance, (d) cost performance, and (e) in exceptional and rare instances approved by our compensation committee, individual and group performance, and (3) capped at three times target; and

• | an equity-based, long-term incentive designed to align compensation with the interests of our stockholders and to enhance retention of our named executive officers consisting of (1) restricted stock units with three-year cliff vesting and (2) performance shares, which vest, if at all, based on our performance against demanding underlying metrics over the applicable three-year performance period.

Because grants under our long-term incentive program are outstanding for three years, at any time we have three over-lapping long-term incentive programs outstanding and the underlying metrics applicable to the performance shares can vary as our compensation committee assesses the effectiveness of our outstanding programs, metrics critical to our long-term success, feedback from our stockholders and compensation trends. The following table describes the performance share metrics (described more fully below) we used for our 2017-2019, 2018-2020 and 2019-2021 long-term incentive programs:

Performance Share Metrics | 2017-2019 | 2018-2020 | 2019-2021
Relative TSR | 40% | 30% | 60%
Total Controllable Cost | 40% | 40% | 40%
Economic Value Added ("EVA") | 20% | 30% |

Our compensation committee, working with the compensation committee’s independent compensation consultant, Meridian Partners, LLC (referred to herein as Meridian), reviews, evaluates and updates our compensation peer group, which includes companies in both similar and different industries, at least annually. For 2019, our compensation committee approved the 34-company peer group more fully described in our CD&A section with (1) market capitalizations ranging from $489 million to approximately $11.6 billion and a median market capitalization of approximately $2.2 billion and (2) revenues ranging from $736 million to approximately $3.7 billion and median revenue of approximately $1.7 billion. Our market capitalization as of December 31, 2019 and revenues for 2019 were $1.8 billion and $1.5 billion, respectively. Due to the differences in size among the companies in our peer group, Meridian uses a regression analysis to adjust survey data results based on our revenue as compared to the revenue of other companies in our peer group.
Pay for Performance
The table below summarizes the performance metrics under our 2019 short-term incentive and 2019-2021 long-term incentive plans:

Incentive Program | Performance Metric | Weighting | Modifier* | Impact on Multiplier
Short-Term Incentive Plan | Adjusted EBITDA | 100% | Safety (TCIR & LCIR) | +/- 10%
|  |  | Quality | +/- 10%
|  |  | Delivery | +/- 10%
|  |  | Cost | +/- 20%
|  |  | Individual | +/- 100%
Long-Term Incentive Plan | Total Controllable Cost | 40% |  |
| TSR | 60% |  |

_______________
* The safety modifier is measured using our total case incident rate ("TCIR") and lost-time case incident rate ("LCIR"), the quality modifier is measured using our no-fault claim rate, the delivery modifier is measured by our on-time delivery rate, and the cost modifier is measured by our manufacturing efficiency. As noted, the individual modifier is discretionary and only used in exceptional and rare instances approved by the compensation committee.
v

The following summarizes our performance against the metrics under our 2019 short-term incentive and 2017-2019 long-term incentive plans:
2019 Short-Term Incentive

Adjusted EBITDA |  |

_______________
* The targets are based on the Adjusted EBITDA required to achieve the designated return on net assets (excluding cash) using our adjusted pre-tax operating income. As noted, our increasing net assets and depreciation raise the year-over-year Adjusted EBITDA targets. While we achieved strong quality performance in 2019, our safety, on-time delivery and cost performance lagged and did not meet our demanding expectations and requirements, resulting in +10%, -1%, -12% and -25% modifiers, respectively, and an overall reduction of our Adjusted EBITDA multiplier of 1.24 to a final multiplier of 0.96.

FEATURES
Ÿ | Pay for performance
Ÿ | Adjusted EBITDA target determined based on return on net assets (excluding cash) using our adjusted pre-tax operating income
Ÿ | Modifiers for safety, quality, delivery and cost performance establishing a strong linkage to strategic non-financial results
Ÿ | In exceptional and rare instances approved by our compensation committee, individual adjustment up to plus or minus 100% based on actual performance, including individual, facility and/or functional area performance
Ÿ | No payout unless we:
| (1) | achieve the threshold Adjusted EBITDA goal of a 7.5% return on our adjusted net assets
| (2) | generate positive adjusted net income
Ÿ | Maximum payout capped at three times the target
Ÿ | Rigorous financial performance goals - target increases with investments and increasingly higher net assets and depreciation

Annual Performance Award Payouts under Short-Term Incentive Plans for our Named Executive Officers

The Adjusted EBITDA targets under our short- term incentive plan reflect the Adjusted EBITDA required to achieve 7.5%, 15% and 35% returns on our net assets (excluding cash) based on adjusted pre-tax operating income at the threshold, target and maximum payout levels. As we have continued to invest in our business our net assets and depreciation have continued to grow and, as a result, the Adjusted EBITDA targets have continued to increase each year. To that end, our Adjusted EBITDA performance at the target level increased 12% from 2018 to 2019. |  |
The table on the right illustrates our annual Adjusted EBITDA performance multiplier for the last three years under our short-term incentive plans before the application of modifiers. See Appendix A to this Proxy Statement for reconciliations of GAAP to non-GAAP measures. |

vi

The Adjusted EBITDA Multiplier under our 2019 Short-Term Incentive Plan is the lowest in the last three years despite our record Adjusted EBITDA performance due to the impact of our additional investments and increasing depreciation which increase our Adjusted EBITDA targets. After the application of modifiers, the final multipliers under our short-term incentive plan for 2017, 2018, and 2019 were 1.51x, 1.18x and 0.96x, respectively, each reflecting the impact of our performance against demanding modifiers.

Annual Performance Award Payouts under Long-Term Incentive Plans
The table below reflects our annual performance award payouts for the last three years under our long-term incentive plans.

Metric | 2015-2017 Plan | 2016-2018 Plan | 2017-2019 Plan
Weighting | Multiplier | Weighted Multiplier | Weighting | Multiplier | Weighted Multiplier | Weighting | Multiplier | Weighted Multiplier
TSR | 100 | % | 1.7x | 1.7x | 60 | % | 0.9x | 0.5x | 40 | % | 1.9x | 0.8x
Cost |  |  |  | 40 | % | 1.18x | 0.5x | 40 | % | 0.9x | 0.4x
EVA |  |  |  |  |  |  | 20 | % | 0.0x | 0.0x
Plan Multiplier |  |  | 1.7x |  |  | 1.0x |  |  | 1.1x

Performance Share Award Payouts Based on Relative TSR
The chart below illustrates the performance share award payouts based on our relative TSR performance for the 2015-2017, 2016-2018 and 2017-2019 long-term incentive programs:

| Performance shares earned, if any, are determined by our TSR over the applicable three year performance period compared to the TSR of the other companies comprising the S&P 600 SmallCap Materials Sector Index. In considering constituents for the S&P SmallCap 600, S&P Dow Jones Indices looks for companies (1) with market capitalizations of between $450 million and $2.1 billion, (2) meeting certain float requirements, (3) with a U.S. domicile, (4) required to file Securities and Exchange Commission ("SEC") annual reports, and (5) listed on a major U.S. exchange, among other factors.
The beginning and ending stock prices used to determine our TSR are calculated using the 20-trading day average preceding the beginning and end of the performance period.
The performance share multiplier is determined by using straight line interpolation based on our TSR percentile ranking within our comparison group based on the table to the right: | Percentile Ranking |  | Multiplier
< 25th |  | 0.0x
25th |  | 0.5x
50th |  | 1.0x
75th |  | 1.5x
≥ 90th |  | 2.0x

Performance Share Award Payout Based on Controllable Cost
Achieving and sustaining a position as a low cost producer is one of our six key strategic initiatives. For our 2017-2019 long-term incentive compensation program, 40% of the performance shares issued to our named executive officers were subject to a controllable cost performance metric that required our company to reduce controllable costs to offset underlying inflation over the three-year performance period to achieve the target payout of performance shares subject to the controllable cost metric. A 9% reduction of controllable costs after offsetting underlying inflation over the same three-year period would result in payout of performance shares equal to two times target and an increase of controllable costs of 9% or more would result in no payout of performance shares subject to the controllable cost metric.
Controllable costs are generally defined as our variable conversion costs which adjust with our product volume and mix plus corporate and plant overhead. Controllable costs also (1) include benefits because we believe that management is required to take actions to influence benefit costs over the performance period and (2) exclude, among other things, major maintenance, research and development and enterprise resource planning costs to ensure that we continue to invest in the future of our company.
Performance Share Award Payout Based on EVA
For 20% of the performance shares granted under our 2017-2019 long-term incentive plan, the payout is determined based on EVA performance, calculated using our adjusted pre-tax operating income in excess of an amount equal to 15% of our net assets.
viii

2019 Total CEO Compensation
As previously noted, the mix of our CEO’s total target compensation is heavily weighted toward performance-based compensation with more than 75% of the total target compensation being at-risk (short- and long-term compensation), 57% of the total target compensation being long-term, and 64% of the long-term target being allocated to performance shares.
For 2019, the market pay analysis performed by Meridian reflected that the total target compensation of our CEO was 5% below the median of our compensation peer group and that our CEO’s (1) base salary was approximately 8% above the median base salary, (2) short-term incentive target was approximately 28% below the median and (3) long-term incentive target was approximately 6% above the median. Regressed Equilar Executive Compensation Survey data received by our compensation committee reflected similar comparisons. Using that information, the compensation committee did not increase our CEO’s 2019 base salary and, instead allocated a total increase in his 2019 total target compensation of 3% to his short- and long-term incentive compensation targets to bring his short-term incentive closer to the median of our compensation peer group, continue to more heavily allocate his total target compensation to his long-term incentive compensation and continue to increase his at-risk compensation and drive the alignment reflected in our compensation philosophy.
As reflected in more detail in the Summary Compensation Table in the CD&A section of this Proxy Statement, in 2019, despite excellent performance and record shipments, record value added revenue, record adjusted earnings per share, record adjusted net income and near record Adjusted EBITDA, the total compensation of our CEO decreased by 2.9% from his 2018 total compensation and decreased by 8.3% from his 2017 total compensation. The year-over-year decreases in total compensation resulted from the increasingly demanding performance metrics in both our short-term and long-term incentive compensation plans as we continue to invest in our business, grow our net assets, increase our depreciation, increase the financial returns required to achieve target performance levels for our financial metrics and increase the level of performance required by our performance metrics and modifiers.
In summary, our incentive compensation programs are designed to demand continuous improvement in our year-over-year results for our CEO and other named executive officers to realize the same year-over-year financial benefit under our incentive compensation plans. We believe that an incentive plan design emphasizing the importance of successful execution of each of our six key strategic initiatives is important to our long-term success and aligns the interests of our CEO and other named executive officers with our success and our stockholders.
HEALTH AND SAFETY OF OUR EMPLOYEES
This Proxy Statement relates to our 2019 performance and compensation, neither of which were effected by the COVID-19 pandemic. Although the COVID-19 pandemic could significantly impact 2020 financial results and compensation outcomes, we have initiated the following actions to address the effect of the COVID-19 pandemic on our employees and business operations:
•Monitoring and implementing local, state and federal guidelines;

• | following the guidelines issued by the Centers for Disease Control and Prevention to mitigate the risk of exposure to COVID-19;

•Implementing additional health and safety protocols for contractors and service providers;
•Developing contingency plans to respond to employees experiencing symptoms;
•Increasing daily communications with plant managers and business leaders; and
•Working with benefits providers and other resources to support our employee.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on June 10, 2020: The Proxy Statement and our Annual Report to Stockholders are available at www.envisionreports.com/kalu.

GENERAL QUESTIONS AND ANSWERS

Q: | Why did I receive a notice about the company’s proxy materials?

A: | You received a Notice of Internet Availability of Proxy Materials (the “Notice”) because you were a holder of record or beneficial owner of shares of common stock of Kaiser Aluminum Corporation as of the close of business on April 17, 2020. We began distributing the Notice and accompanying proxy materials on or about April 29, 2020. Our board of directors is soliciting your proxy to vote at the 2020 Annual Meeting of Stockholders (the “Annual Meeting”). Our board of directors has made our proxy materials, including the Notice, this Proxy Statement, our Annual Report and proxy card, available to you on the internet, or upon your request, has delivered printed proxy materials to you in connection with the solicitation of proxies for use at the Annual Meeting. Our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Annual Report”), along with this Proxy Statement and all other relevant corporate governance materials, are also available at www.kaiseraluminum.com.

Q: | Why did I receive a notice in the mail regarding the internet availability of proxy materials instead of the proxy materials themselves, and how can I get the materials?

A: | In accordance with rules adopted by the Securities and Exchange Commission, we have elected to furnish proxy materials, including this Proxy Statement and our Annual Report, to our stockholders by providing access to such documents on the internet instead of mailing printed copies. Most stockholders will not receive printed copies of the proxy materials unless they request them. Instead, the Notice, which was mailed to most of our stockholders, will instruct you as to how you may access and review all of the proxy materials on the internet. The Notice also instructs you as to how you may submit your proxy on the internet. If you would like to receive a paper copy of our proxy materials, you should follow the instructions for requesting such materials included in the Notice

Q: | When is the Annual Meeting and where will it be held?

A: | The Annual Meeting will be held on Wednesday, June 10, 2020, at 9:00 a.m., local time, at our corporate office, located at 27422 Portola Parkway, Suite 200, Foothill Ranch, California 92610.

As part of our contingency planning regarding novel coronavirus (COVID-19), we are preparing for the possibility that the date, time or location of the Annual Meeting may be changed or that the Annual Meeting may be held by means of remote communication (sometimes referred to as a "virtual" meeting). If we take this step, we will announce the decision to do so in advance through a press release and public filing with the Securities and Exchange Commission, and details will be available at www.kaiseraluminum.com.

Q: | Who may attend the Annual Meeting?

A: | All of our stockholders of record may attend the Annual Meeting.

Q: | Who is entitled to vote?

A: | Stockholders as of the close of business on April 17, 2020 are entitled to vote at the Annual Meeting. Each share of our common stock is entitled to one vote.

Q: | On what am I voting?

A: | You will be voting on:

• | The election of three members to our board of directors to serve until our 2023 annual meeting of stockholders;

• | The approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement;

• | The ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020; and

• | Such other business as may properly come before the Annual Meeting or any adjournments.

1

Q: | How does the board of directors recommend that I vote?

A: | The board of directors recommends that you vote your shares:

• | "FOR ALL" the director nominees identified in "Proposals Requiring Your Vote - Proposal 1 - Election of Directors" below;

• | "FOR" the approval , on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement; and

• | "FOR" the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020.

Q: | How can I vote?

A: | You can vote at the Annual Meeting or you can vote prior to the Annual Meeting by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy without delay.

Q: | How do I vote by proxy?

A: | If you choose to vote your shares by proxy, you have the following options:

• | Over the Internet: You can vote over the Internet at the website shown on your proxy card. Internet voting will be available 24 hours a day, seven days a week, until 11:59 p.m., Eastern Time, on Tuesday, June 9, 2020.

• | By telephone: You can vote by telephone by calling the toll-free number shown on your proxy card. Telephone voting will be available 24 hours a day, seven days a week, until 11:59 p.m., Eastern Time, on Tuesday, June 9, 2020.

• | By mail: You can vote by mail by completing, signing and dating your proxy card and returning it in the enclosed prepaid envelope.

Q: | I want to attend the Annual Meeting and vote. How do I obtain directions to the Annual Meeting?

A: | You may obtain directions to the Annual Meeting by calling us at (949) 614-1740.

Q: | What constitutes a quorum?

A: | As of April 17, 2020, the record date, 15,789,594 shares of our common stock were issued and outstanding. A majority of these shares present or represented by proxy will constitute a quorum for the transaction of business at the Annual Meeting. If you properly vote by proxy by submitting your voting instructions over the Internet, by telephone or by mail, then your shares will be counted as part of the quorum. Abstentions or votes that are withheld on any matter will be counted towards a quorum but will be excluded from the vote relating to the particular matter under consideration. Broker non-votes are counted towards a quorum but are excluded from the vote with respect to the matters for which they are applicable. A broker non-vote occurs when a broker holding shares for a beneficial owner does not vote on a particular proposal because the broker does not have discretionary voting power with respect to that proposal and has not received instructions with respect to that proposal from the beneficial owner. Among our proposals, brokers will have discretionary voting power only with respect to the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020.

Q: | What are the voting requirements for the proposals?

A: | There are different voting requirements for the proposals.

• | Each director will be elected by an affirmative vote of the majority of the votes cast with respect to the director in an uncontested election. A “majority” of the votes cast with respect to a director means the number of votes for the director exceeds the number of votes withheld from the director. If an incumbent director nominee receives a greater number of votes withheld than in favor of his or her election in an uncontested election, the nominee must promptly tender his or her resignation, and the board of directors will decide, through a process managed by the nominating and corporate governance committee, whether to accept the resignation, taking into account its fiduciary duties to our

2

company and our stockholders. The board of director's explanation of its decision will be promptly disclosed in a Form 8-K furnished to the Securities and Exchange Commission. An election of directors is considered to be contested if there are more nominees for election than positions on the board of directors to be filled by election at the meeting of stockholders. In the event of a contested election, each director will be elected by a plurality vote of the votes cast at such meeting. The election of directors at the Annual Meeting is uncontested.

• | The affirmative vote of the holders of a majority of shares of our common stock present or represented by proxy at the Annual Meeting and entitled to vote on the subject matter and actually voted on the proposal is necessary (1) to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement, and (2) to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020. If you abstain from voting on the proposal to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement and/or the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020, your shares will not be counted in the vote for such proposal(s) and will have no effect on the outcome of the vote.

Q: | If my shares are held in "street name" by my broker, will my broker vote my shares for me?

A: | As discussed above, among our proposals, brokers will have discretionary voting power only with respect to the proposal to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020. To be sure your shares are voted, you should instruct your broker to vote your shares using the instructions provided by your broker.

Q: | What will happen if the compensation of the company's named executive officers is not approved by the stockholders on an advisory basis?

A: | Because this is an advisory vote, our board of directors and compensation committee will not be bound by the approval of, or the failure to approve, the compensation of our named executive officers as disclosed in this Proxy Statement. The board of directors and the compensation committee, however, value the opinions that our stockholders express in their votes and expect to consider the outcome of the vote when determining future executive compensation programs.

Q: | What will happen if the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020 is not ratified by the stockholders?

A: | Pursuant to the audit committee charter, the audit committee of our board of directors has sole authority to appoint our independent registered public accounting firm, and the audit committee will not be bound by the ratification of, or failure to ratify, the selection of Deloitte & Touche LLP. The audit committee will, however, consider any failure to ratify the selection of Deloitte & Touche LLP in connection with the appointment of our independent registered public accounting firm the following year.

Q: | Can I change my vote after I give my proxy?

A: | Yes. If you vote by proxy, you can revoke that proxy at any time before voting takes place at the Annual Meeting. You may revoke your proxy by:

•voting again over the Internet or by telephone no later than 11:59 p.m., Eastern Time, on Tuesday, June 9, 2020;
•submitting a properly signed proxy card with a later date;

• | delivering, no later than 5:00 p.m., Eastern Time, on Tuesday, June 9, 2020, written notice of revocation to our Secretary, c/o Computershare, P.O. Box 43126, Providence, Rhode Island 02940-5138; or

• | attending the Annual Meeting and voting.

Your attendance alone will not revoke your proxy. To change your vote, you must also vote at the Annual Meeting. If you instruct a broker to vote your shares, you must follow your broker's directions for changing those instructions.

Q: | What does it mean if I receive more than one proxy card?

A: | If you receive more than one proxy card, it is because your shares are held in more than one account. You must vote each proxy card to ensure that all of your shares are voted at the Annual Meeting.

3

Q: | Who will count the votes?

A: | Representatives of Computershare, our transfer agent, will tabulate the votes and act as inspectors of election.

Q: | How much will this proxy solicitation cost?

A: | We will bear the cost of the solicitation of proxies. We have hired MacKenzie Partners, Inc. to assist us in the distribution of proxy materials and solicitation of votes at a cost not to exceed $10,000, plus out-of-pocket expenses. We will reimburse brokerage firms and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to the owners of our common stock. Our officers and regular employees may also solicit proxies, but they will not be specifically compensated for these services. In addition to the use of the mail, proxies may be solicited personally or by telephone by our employees or by MacKenzie Partners.

PROPOSALS REQUIRING YOUR VOTE
Proposal 1 - Election of Directors
General
We have a diverse and independent board of directors. Our board of directors currently has 12 members, consisting of our CEO and 11 independent directors. Our current directors are:

Carolyn Bartholomew | Lauralee E. Martin
David Foster | Alfred E. Osborne, Jr., Ph.D.
Leo Gerard | Teresa M. Sebastian
L. Patrick Hassey | Donald J. Stebbins
Jack A. Hockema | Thomas M. Van Leeuwen
Emily Liggett | Brett E. Wilcox

Mr. Hockema, our CEO, serves as our Chairman of the Board, and Dr. Osborne serves as our Lead Independent Director. If each of our Class II director nominees is elected, because Ms. Bartholomew is not standing for re-election at the Annual Meeting, the size of our board of directors will be reduced from 12 to 11 members.
Our board of directors represents a breadth of experience and diversity in perspective and background, as reflected in the summary of their collective qualifications below. Additionally, our current directors have a broad range of tenures, from less than one year to almost 19 years of service, with an average tenure of approximately nine years. We believe this balances institutional knowledge and experience with new perspectives and ideas.
Strategic Board Skills, Experience and Attributes

Public Board of Directors Experience |  | Industry-Specific |  | Economic, Regulatory and/or Policy |  | Diversity
Leadership /Management |  | Labor / Talent Management and Development |  | Financial / Investment |  | International Industrial

Our amended and restated certificate of incorporation and bylaws provide for a classified board of directors consisting of three classes. The term of our Class II directors expires at the Annual Meeting; the term of our Class III directors will expire at the 2021 annual meeting of stockholders; and the term of our Class I directors will expire at the 2022 annual meeting of stockholders.
Ms. Bartholomew, who was designated by the United Steel, Paper and Foresting, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO, CLC (referred to herein as the USW) as a director candidate pursuant to the terms of our Director Designation Agreement with the USW (described under “Corporate Governance - Director Designation Agreement”), has not been designated by the USW for re-election when her term ends at the Annual Meeting.
Board Refreshment and Director Succession Planning
We are committed to board refreshment and have added four highly qualified and independent directors to our board since 2018. The table below illustrates the tenure of our directors:
5

Board Tenure | Number of Directors | Percentage
0-5 Years | 4 | 33%
6-10 Years | 2 | 17%
11+ Years | 6 | 50%

We thoughtfully plan for director succession and board refreshment. By developing and following a long-term succession plan, the board has an ongoing opportunity to:
•evaluate the depth and diversity of experience of our board;
•anticipate and plan for changes, including retirements;
•constructively engage with the USW;
•expand and replace key skills and experience that support our strategies;
•build on our record of board diversity; and
•maintain a balanced mix of tenures.
The nominating and corporate governance committee also plans for the orderly succession of our independent lead director and of the chairs of our board's five committees, providing for the identification of potential successors, their development and the transition of responsibilities.
Board Composition and Diversity
Bringing together informed directors with different perspectives and backgrounds, in a well-managed and constructive environment, fosters thoughtful and innovative decision-making. We have a policy of encouraging diversity of gender, ethnicity, age and background, as well as a range of tenures on the board to ensure both continuity and fresh perspectives among our directors. Our directors exhibit a balanced mix of tenures, ages, independence and diversity.

Gender Diversity |  | Ethnic Diversity |  | Independence
33% |  | 17% |  | 92%

Nominees for Class II Directors
The nominating and corporate governance committee of our board of directors has recommended, and our board of directors has approved, the nomination of the three nominees listed below. The nominees have indicated their willingness to serve as members of the board of directors if elected; however, in case any nominee becomes unavailable for election to the board of directors for any reason not presently known or contemplated, the proxy holders have discretionary authority to vote proxies for a substitute nominee. Proxies cannot be voted for more than three nominees.
The board of directors recommends a vote "FOR ALL" of the persons nominated by the board of directors.
Set forth below is information about the Class II director nominees, including their ages, present principal occupations, other business experiences, directorships in other public companies in the past five years, membership on committees of our board of directors, and reasons why each individual nominee's specific experience, qualifications, attributes or skills led the nominating and corporate governance committee to recommend, and our board of directors to conclude, that the nominee should serve as a director of the company.

Proposal 2 - Advisory Vote to Approve Named Executive Officer Compensation
In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Securities Exchange Act of 1934, referred to herein as the Exchange Act, we ask stockholders to vote annually on a non-binding, advisory resolution to approve our named executive officer compensation. The vote is not intended to address any specific component of our executive compensation program, but rather the overall compensation of our named executive officers as described in this Proxy Statement. The text of the resolution is as follows:
RESOLVED, that the compensation paid to the named executive officers of Kaiser Aluminum Corporation, as described in the proxy statement for the company's 2020 annual meeting of stockholders pursuant to Item 402 of Regulation S-K (which disclosure includes the "Executive Compensation - Compensation Discussion and Analysis" section and the Summary Compensation Table and other compensation tables and related narrative discussions), is hereby APPROVED.
In 2019, we had record results despite formidable headwinds, achieving record value added revenue, record Adjusted EBITDA, record adjusted net income and record adjusted earnings per share. In addition, we continued to invest in our business for further growth and efficiency and we returned over $84 million to our stockholders through share repurchases and dividends consistent with our capital allocation priorities.
As described in further detail in the CD&A section, our compensation structure was developed to achieve the following objectives, which we believe are critical for enhancing stockholder value and our long-term success and sustainability:

• | creating alignment between our senior management and our stockholders by rewarding our senior management for achieving strategic goals that successfully drive our operations and enhance our stockholder return;

13

• | attracting, motivating and retaining highly experienced executives vital to our short-term and long-term success, profitability and growth; and

• | correlating our senior management compensation with our actual short- and long-term performance.

The compensation committee reviewed our compensation program for 2019. The review included consideration of stockholder feedback, the over 84% approval of the 2019 advisory vote to approve our named executive officer compensation, and discussions with Meridian and management regarding existing and contemplated market practices, as well as the structure and objectives of each component of our compensation. Upon completion of that review, the compensation committee determined that the compensation of our named executive officers in 2019 would consist primarily of the following components:

• | a base salary (1) compensating each named executive officer based on the level of responsibility, individual expertise and prior experience and (2) providing a fixed amount of cash compensation upon which our named executive officers can rely;

• | a short-term annual cash incentive (1) payable only if our company achieves a certain Adjusted EBITDA performance level which has continued to increase, resulting in increasingly demanding performance to realize the same or similar payouts year-over-year as more fully described below, (2) adjusted for (a) our safety performance based on our total case incident rate, or TCIR, which is the average number of work-related injuries incurred per 100 workers during a one-year period, as well as lost-time case incident rate, or LCIR, which is the average number work-related injuries that resulted in lost or restricted days or job transfer incurred per 100 workers during a one-year period, (b) our quality performance based on our no-fault claim rate, (c) delivery performance based on our on-time delivery rate, (d) cost performance based on our manufacturing efficiency, and (e) in exceptional and rare instances approved by the compensation committee, individual performance based on individual, facility, and/or functional performance, and (3) capped at three times target; and

• | an equity-based, long-term incentive designed to align compensation with the interests of our stockholders and to enhance retention of our named executive officers consisting of (1) restricted stock units with three-year cliff vesting and (2) performance shares, 60% of which that vest, if at all, based on our TSR, compared to the TSR of our peers in the S&P SmallCap 600 Materials Index and 40% of which that vest, if at all, based on our total controllable cost performance, each over the 2019-2021 performance period.

Our compensation committee, working with Meridian, reviews, evaluates and updates our compensation peer group, which includes companies in both similar and different industries, at least annually. For 2019, our compensation committee approved the 34-company peer group more fully described in our CD&A with (1) market capitalizations ranging from $489 million to approximately $11.6 billion and a median market capitalization of approximately $2.2 billion and (2) revenues ranging from $736 million to approximately $3.7 billion and median revenue of approximately $1.7 billion. Our market capitalization as of December 31, 2019 and revenues for 2019 were $1.8 billion and $1.5 billion, respectively. Due to the differences in size among the companies in our peer group, Meridian uses a regression analysis to adjust survey data results based on our revenue as compared to the revenue of other companies in our peer group.
For 2019, the market pay analysis performed by Meridian reflected that the total target compensation of our CEO was 5% below the median of our compensation peer group and that our CEO’s (1) base salary was approximately 8% above the median base salary, (2) short-term incentive target was approximately 28% below the median and (3) long-term incentive target was approximately 6% above the median. Regressed Equilar Executive Compensation Survey data received by our compensation committee reflected similar comparisons. Using that information, the compensation committee did not increase our CEO’s 2019 base salary and, instead allocated a total increase in his 2019 total target compensation of 3% to his short- and long-term incentive compensation targets to bring his short-term incentive closer to the median of our compensation peer group, continue to more heavily allocate his total target compensation to his long-term incentive compensation and continue to increase his at-risk compensation and drive the alignment reflected in our compensation philosophy.
We no longer maintain a defined benefit pension plan or retiree medical program that covers members of senior management. Retirement benefits to our senior management, including our named executive officers, are provided through a defined contribution retirement program consisting of a 401(k) plan (which we refer to as our Savings Plan) and a nonqualified and unsecured deferred compensation plan (which we refer to as our Restoration Plan) intended to restore benefits that would be payable to designated participants in our Savings Plan but for the limitations on benefit accruals and payments imposed by the Internal Revenue Code of 1986 (referred herein as the Code).
14

For 2019, approximately 75% of the target total compensation of our CEO and our COO, and approximately 55% to 68% of the target total compensation of our other named executive officers, consisted of at-risk compensation, which we define as compensation that either (1) will be realized, if at all, only if certain financial performance levels are achieved as in the case of our annual short-term incentive and the portion of our long-term incentive consisting of performance shares or (2) is time-based as in the case of the portion of our long-term incentive compensation consisting of restricted stock units.
Our compensation structure also supports our corporate governance practices, which further align the interests of senior management and our stockholders. The table below sets forth the best practice compensation features we have adopted as of 2019.

Best Practice Compensation Features |  |  |
What We Do ü |  | What We Don't Do û
ü | DO align pay and performance by linking a significant portion of total compensation to company performance, including financial, safety, quality, delivery and cost performance, as well as individual performance |  | û | NO compensation or incentives that encourage unnecessary or excessive risk taking
ü | DO balance both short-term (one-year) and long-term (three-year) performance across our incentive programs |  | û | NO repricing or buyout of "underwater" stock options or appreciation rights without stockholder approval
ü | DO enhance retention with time-based, three-year cliff vesting for restricted stock unit awards |  | û | NO pledging of our securities
ü | DO subject the vesting of 50% (64% for our CEO and 67% for our COO) of long-term incentive awards to performance targets based on relative TSR, controllable cost and EVA, each over a three-year performance period |  | û | NO hedging or speculative transactions involving our securities
ü | DO maintain rigorous stock ownership guidelines (6x base salary/base retainer for CEO, COO and non-employee directors and 3x for other executive officers) |  | û | NO guaranteed payout for cash incentive compensation
ü | DO maintain a clawback policy for both equity and cash awards |  | û | NO excessive perquisites or other benefits
ü | DO cap payouts for awards under both of our short- and long-term incentive plans |  | û | NO evergreen equity plan provisions
ü | DO appoint a compensation committee comprised solely of independent directors |  | û | NO dividend equivalents on unearned performance shares
ü | DO use an independent compensation consultant |  |  |

We believe our incentive compensation programs are designed to demand continuous improvement in our year-over-year results for our named executive officers to realize the same year-over-year financial benefit under our compensation plans. We also believe that design emphasizing the importance of successful execution of each of our six key strategic initiatives is important to our long-term success and aligns the interests of our named executive officers with our stockholders.
We urge our stockholders to review our CD&A which describes our compensation philosophy and programs in detail and to approve the compensation of our named executive officers. While this vote to approve our named executive officer compensation is non-binding and solely advisory in nature, our board of directors and the compensation committee value the opinions of our stockholders and expect to consider the outcome of the vote when determining future executive compensation programs. We hold this advisory vote to approve our named executive officer compensation on an annual basis, and the next such vote is expected to be conducted at our 2021 annual meeting.
The board of directors recommends a vote "FOR" the approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement.
15

Proposal 3 - Ratification of the Selection of our Independent Registered Public Accounting Firm
Pursuant to the audit committee charter, the audit committee has the sole authority to retain an independent registered public accounting firm for our company. The board of directors requests that the stockholders ratify the audit committee's selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020.
The audit committee will not be bound by the ratification of, or failure to ratify, the selection of Deloitte & Touche LLP, but the audit committee will consider any failure to ratify the selection of Deloitte & Touche LLP in connection with the appointment of our independent registered public accounting firm for 2021.
The board of directors recommends a vote "FOR" the ratification of the audit committee's selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2020.

CORPORATE GOVERNANCE
Our board of directors is responsible for providing effective governance over the affairs of our company. Our corporate governance practices are designed to align the interests of our board of directors and management with those of our stockholders and to promote honesty, integrity and our corporate values throughout the company. Highlights of our corporate governance practices are described below.
A copy of the current charter, as approved by our board of directors, for each of the executive committee, audit committee, compensation committee, nominating and corporate governance committee and talent development committee, and a copy of each of our corporate governance guidelines and our code of business conduct and ethics, which applies to all of our directors employees, including our executive officers, are available on our website at www.kaiseraluminum.com under "Investor Relations - Corporate Governance." Furthermore, we will post any amendments to our code of business conduct and ethics, or waivers of the code for our directors or executive officers, on our website at www.kaiseraluminum.com under "Investors- Corporate Governance."
Corporate Governance Highlights

Board Structure | ü | Highly independent - 92% of the directors are independent; 100% of the audit committee, compensation committee and nominating and corporate governance committee are independent
ü | Diverse in perspective and background - 33% of our directors are gender diverse and 17% of our directors are ethnically diverse

Board Leadership Structure
Mr. Hockema, our CEO, serves as the Chairman of the Board, and Dr. Osborne serves as our Lead Independent Director. We believe that Mr. Hockema's experience with our company and in the metals industries, the independence of the other directors, our governance structure and the interaction between and among Mr. Hockema, our Lead Independent Director and the other directors make our board leadership structure the most appropriate for our company and our stockholders. As a result of his substantial experience with our company and in the metals industries, Mr. Hockema is uniquely qualified to provide clear leadership for our company and a single point of accountability.
Our corporate governance guidelines and governance structure require a Lead Independent Director to be selected by a majority of the independent directors, thereby ensuring that there is independent leadership within our board of directors and allowing our independent directors to function as a body distinct from management and evaluate the performance of Mr. Hockema and our management independently and objectively. The responsibilities of our Lead Independent Director include:
•establishing the agenda for executive sessions;
•calling a meeting of independent directors upon the request of a majority of independent directors;
•serving as a liaison between our independent directors and our CEO;
•presiding at meetings of our independent directors;
•soliciting advice and input from our independent board members; and
17

• | routinely meeting and conferring with our CEO to address comments, issues and areas of interest expressed or identified by our independent directors, to assess the governance of our board of directors and our company, and to review board responsibilities, meeting schedules, meeting agenda and information requested or otherwise provided to our directors routinely or in connection with meetings of our board of directors.

Each of the audit, compensation, nominating and corporate governance, and talent development committees consists solely of independent directors. The chair of each committee of our board of directors serves as a liaison to keep our full board of directors and our CEO apprised of the work performed by their respective committees at each of our regularly scheduled board meetings and as otherwise required. Finally, under our bylaws, special meetings of our board of directors may be called by a majority of our board members, 11 of 12 of whom are currently independent.
Under our corporate governance guidelines, each member of our board of directors may submit items to be included on the agenda for any meeting of our board of directors and raise subjects that are not on the agenda at any meeting of our board of directors. In addition, our independent directors are required to meet at least quarterly in executive sessions at which only independent directors are present. Additionally, we encourage direct communication among our directors and with our CEO before, during and after formal board and committee meetings and facilitate those communications around our scheduled meetings. Our directors also have full access to our officers, employees and advisors.
Risk Oversight
We have policies in place to identify, assess and manage potential risks and to continually review the procedures that we have designed and implemented to mitigate those risks. We believe that our board of directors provides effective oversight of the risk management function. Under its charter, the audit committee of our board of directors is responsible for discussing our risk management policies, including, without limitation, the steps taken and to be taken to monitor and control our major financial risk exposures. The compensation committee of our board of directors is responsible for assessing risks associated with our compensation policies. In addition, our full board of directors is actively engaged in the review and assessment of our risk management policies, conducts a comprehensive review at least annually during a regularly scheduled board meeting and routinely requests that specific risk-related items be included on board and committee meeting agendas, including by way of example, the COVID-19 pandemic, our COVID-19 contingency planning and health and safety measures implemented to protect our employees. We also engage in an ongoing enterprise risk management process pursuant to which we formally identify, categorize and assess our risks and risk mitigation strategies and routinely update the audit committee and our full board of directors regarding this process.
Director Independence
Our corporate governance guidelines require that a majority of the members of our board of directors satisfy the independence requirements set forth in the rules of the Nasdaq Stock Market. We refer to these requirements as the general independence criteria. Additionally, the audit committee charter, compensation committee charter and nominating and corporate governance committee charter require that all respective committee members satisfy the general independence criteria. There are no family relationships among our officers or directors.
Based upon information requested from and provided by each of our directors concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that each of Mmes. Bartholomew, Liggett, Martin and Sebastian and Messrs. Foster, Gerard, Hassey, Osborne, Stebbins, Van Leeuwen and Wilcox, representing 11 of our 12 directors, satisfies the general independence criteria. The twelfth director, Mr. Hockema, cannot meet the independence requirement as our CEO. In making such determination, our board of directors considered the relationships that each of our directors had with our company and all other facts and circumstances our board of directors deemed relevant in determining the independence of each of our directors in accordance with the general independence criteria.
18

Director Designation Agreement
On July 6, 2006, we entered into a Director Designation Agreement with the USW under which the USW has certain rights to designate board candidates for nomination. We believe that:

• | the USW has been a good steward of its rights under the Director Designation Agreement;

• | the nominees of the USW have made significant contributions to our board of directors;

• | the Director Designation Agreement reflects the constructive relationship between the USW and our company; and

• | the Director Designation Agreement facilitates discussions with the USW in regard to our strategy, our key strategic initiatives, the critical skills needed on our board of directors and other matters of mutual interest.

Accordingly, in connection with the renewal and ratification of a new five-year collective bargaining agreement with members of the USW at our Spokane, Washington and Newark, Ohio facilities, in December 2019, the Director Designation Agreement which was set to expire on December 31, 2020 was extended to December 31, 2025. Under the Director Designation Agreement, the USW generally has the right to designate for nomination the minimum number of director candidates necessary to ensure that, assuming the nominated candidates are elected by our stockholders, at least 40% of the members of our board of directors have been nominated by the USW, except that we have the ability to increase the size of the board of directors from 10 to up to 12 members without increasing the number of candidates that the USW has the right to designate for nomination.
The Director Designation Agreement contains requirements as to the timeliness, form and substance of the notice the USW must give to the nominating and corporate governance committee in order to nominate candidates. The nominating and corporate governance committee is required to determine in good faith whether each properly submitted candidate satisfies the qualifications set forth in the Director Designation Agreement. Pursuant to the terms of the Director Designation Agreement, if the nominating and corporate governance committee determines that a nominated candidate satisfies the qualifications, the committee will, unless otherwise required by its fiduciary duties, recommend the candidate to our board of directors for inclusion in the slate of directors to be recommended by the board of directors in our proxy statement. Similarly, the board of directors will, unless otherwise required by its fiduciary duties, accept the recommendation and include the candidate in the slate of directors that the board of directors recommends. Notwithstanding the foregoing, the USW may not nominate an incumbent candidate without our approval.
In addition, the Director Designation Agreement provides that, so long as our board of directors maintains an audit committee, executive committee or nominating and corporate governance committee, each of these committees will, unless otherwise required by the fiduciary duties of our board of directors, include at least one director nominated by the USW (provided at least one director nominated by the USW is qualified to serve on the applicable committee as determined in good faith by our board of directors). Current members of our board of directors that have been nominated by the USW are Mmes. Bartholomew and Sebastian and Messrs. Foster, Gerard and Wilcox. Ms. Bartholomew's tenure will end at the Annual Meeting.

Executive Committee
The executive committee of our board of directors manages our business and affairs requiring attention prior to the next regular meeting of our board of directors. However, the executive committee does not have the power to (1) approve or adopt, or recommend to our stockholders, any action or matter expressly required by law to be submitted to our stockholders for approval, (2) adopt, amend or repeal the bylaws of our company, or (3) take any other action reserved for action by our board of directors pursuant to a resolution of our board of directors or otherwise prohibited to be taken by the executive committee by law or pursuant to our amended and restated certificate of incorporation or bylaws. The executive committee of our board of directors is comprised of the chairman of the board of directors and the chair of each of the other outstanding committees of our board of directors.
The executive committee charter requires that a majority of the members of the executive committee satisfy the general independence criteria. In addition, the members of the executive committee must include the chairman of our board of directors and at least one of the directors nominated by the USW. The executive committee is currently comprised of the chairman of our board of directors and the chair of each of the other standing committees of the board of directors.

Audit Committee
The audit committee of our board of directors oversees our accounting and financial reporting practices and processes and the audit of our financial statements on behalf of our board of directors. The audit committee is responsible for appointing, compensating, retaining and overseeing the work of our independent accounting firm. Other duties and responsibilities of the audit committee include:

• | establishing hiring policies for employees or former employees of the independent accounting firm;

• | reviewing our systems of internal accounting controls;

• | discussing risk management policies;

• | approving related-party transactions;

• | establishing procedures for complaints regarding financial statements or accounting policies; and

• | performing other duties delegated to the audit committee by our board of directors from time to time.

The audit committee charter requires that all members of the audit committee satisfy the general independence criteria. The charter also requires that no audit committee member may have participated in the preparation of our financial statements during the three years prior to his or her appointment as a member and that each audit committee member be able to read and understand fundamental financial statements, including a balance sheet, an income statement and a cash flow statement. Additionally, at least one member of the audit committee must have had past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience which results in that individual's financial sophistication, including being or having been a chief executive officer, chief financial officer or other senior officer with financial oversight responsibilities and that member or another member must have sufficient education or experience to have acquired the attributes necessary to meet the criteria of an "audit committee financial expert," as that term is defined in the rules promulgated by the SEC. In addition, the members of the audit committee must include at least one of the directors nominated by the USW so long as at least one such director is appropriately qualified.
Our board of directors has determined that all seven members of the audit committee (1) meet the general independence criteria, the heightened independence criteria for members of the audit committee set forth in the rules of the Nasdaq Stock Market and the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act, and (2) are able to read and understand fundamental financial statements. Our board of directors has also determined that no member of the audit committee participated in the preparation of our financial statements during the three years prior to their appointment as members of the committee. Finally, our board of directors has determined that Mmes. Liggett, Martin and Sebastian and Messrs. Van Leeuwen and Wilcox satisfy the financial sophistication criteria described above and satisfy the criteria necessary to serve as the "audit committee financial expert," in each case based on his or her experience described in "Proposals Requiring Your Vote - Proposal 1 - Election of Directors" above.
Compensation Committee
General
The compensation committee of our board of directors establishes and administers our policies, programs and procedures for compensating our senior management, including determining and approving the compensation of our executive officers. Other duties and responsibilities of the compensation committee include:

• | administering plans adopted by our board of directors that contemplate administration by the compensation committee, including our 2016 Equity and Incentive Compensation Plan (referred to herein as our 2016 Plan);

• | overseeing regulatory compliance with respect to compensation matters;

• | reviewing director compensation; and

• | performing other duties delegated to the compensation committee by our board of directors from time to time.

21

The compensation committee solicits the views of our CEO on compensation matters, including as they relate to our compensation of the other members of senior management reporting to our CEO. The compensation committee has retained Meridian to advise the compensation committee on all matters related to compensation of our CEO and other members of senior management. The compensation committee has reviewed the factors that could affect, and has assessed, Meridian's independence. Based on this review, the compensation committee has determined there are no conflicts of interest that have been raised by Meridian's work.
Meridian's services include (1) providing competitive market data and related assessments of executive compensation as background against which the compensation committee considers executive compensation, (2) preparing and reviewing tally and compensation summary sheets for our named executive officers, (3) apprising the compensation committee of trends and best practices associated with executive and director compensation, (4) providing support with respect to legal, regulatory and accounting considerations impacting compensation and benefit programs, (5) the development and review of a list of compensation peer group companies, and (6) attending meetings of the compensation committee and our board of directors when requested. These services are typically directed by the compensation committee and coordinated with our human resources department.
The compensation committee charter requires that all members of the compensation committee satisfy the general independence criteria and the heightened independence criteria for members of the compensation committee set forth in the rules of the Nasdaq Stock Market, as well as qualify as "non-employee directors" within the meaning of Rule 16b-3 promulgated under the Exchange Act. Our board of directors has determined that all five members of the compensation committee meet the applicable independence criteria.
The compensation committee may create one or more subcommittees, each subcommittee to consist of one or more members of the committee, and may delegate to the subcommittee any or all of the powers and authority of the committee.
Compensation Committee Interlocks and Insider Participation
None of Ms. Martin or Messrs. Hassey, Quinn, Stebbins, Van Leeuwen or Wilcox, the members of the compensation committee during 2019, (1) was an officer or employee of our company during 2019, (2) was formerly an officer of our company, or (3) had any relationships requiring disclosure by us under the rules of the Securities and Exchange Commission with respect to certain relationships and related-party transactions. Furthermore, none of our executive officers currently serves, or served during the last fiscal year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee.
Nominating and Corporate Governance Committee
The nominating and corporate governance committee of our board of directors identifies individuals qualified to become members of our board of directors, recommends candidates to fill vacancies and newly-created positions on our board of directors, recommends director nominees for election by stockholders at the annual meetings of stockholders and develops and recommends to our board of directors our corporate governance guidelines.
We believe that the nominating and corporate governance committee considers an appropriate range of criteria in assessing candidates for a position on the board of directors. Our corporate governance guidelines require that the criteria utilized by the corporate governance committee in assessing such candidates include factors such as judgment, diversity, integrity, experience with businesses and other organizations of comparable size, the interplay of a candidate's experience with the experience of other members of the board of directors and anything else that may bear upon the extent to which a candidate would be a desirable addition to our board of directors and any committees of our board of directors. The policies relating to the recommendation of director candidates adopted by the nominating and corporate governance committee are designed to ensure flexibility with respect to the process of evaluating candidates and do not establish specific minimum qualifications that an individual must meet to become a member of our board of directors. The nominating and corporate governance committee believes that our company is best served when it can draw from a variety of experiences and backgrounds provided by members of our board of directors. However, the nominating and corporate governance committee also believes that our company is best served when each member of the board of directors:

• | exhibits strong leadership in his or her particular field or area of expertise;

• | possesses the ability to exercise sound business judgment;

• | has a strong educational background or equivalent life experiences;

22

• | has substantial experience both in the business community and outside the business community;

• | contributes positively to the existing collaborative culture among members of our board of directors;

• | represents the best interests of all of our stockholders and not just one particular constituency;

• | has experience as a senior executive of a company of significant size or prominence or another business or organization comparable to our company;

• | possesses skills and experience which make him or her a desirable addition to a standing committee of our board of directors;

• | consistently demonstrates integrity and ethics in his or her professional and personal life; and

• | has the time and ability to participate fully in activities of our board of directors, including attendance at, and active participation in, meetings of our board of directors and the committee or committees of which he or she is a member.

Other duties and responsibilities of the nominating and corporate governance committee include:

• | assisting in management succession planning, including with respect to the chairman of our board of directors and our CEO;

• | considering possible conflicts of interest of members of our board of directors and management and making recommendations to prevent, minimize or eliminate such conflicts of interests;

• | evaluating whether an incumbent director should be nominated for re-election to our board of directors upon expiration of the incumbent's term;

• | making recommendations to our board of directors regarding the appropriate size of our board of directors; and

• | performing other duties delegated to the nominating and corporate governance committee by our board of directors from time to time.

The nominating and corporate governance committee has adopted policies and procedures by which our stockholders may submit director candidates to the nominating and corporate governance committee for consideration. If the nominating and corporate governance committee receives, by a date not less than 120, nor more than 150, calendar days before the anniversary of the date that the proxy statement was mailed to stockholders in connection with our previous year's annual meeting, a recommendation for a director nominee from a stockholder or group of stockholders that beneficially owned more than 5% of our outstanding common stock for at least one year as of the date of the recommendation, then such director candidate will be considered and evaluated by the nominating and corporate governance committee for the annual meeting immediately succeeding the date that proper written notice was timely delivered to and received by the nominating and corporate governance committee. When the date of our annual meeting of stockholders changes by more than 30 calendar days from the previous year's annual meeting, the written notice of the recommendation for the director candidate will be considered timely if, and only if, it is received by the nominating and corporate governance committee no later than the close of business on the tenth calendar day following the first day on which notice of the date of the upcoming annual meeting is publicly disclosed by us.
Written notice from an eligible stockholder or group of eligible stockholders to the nominating and corporate governance committee recommending a director candidate must contain or be accompanied by:

• | proof that the stockholder or group of stockholders submitting the recommendation has beneficially owned, for the required one-year holding period, more than 5% of our outstanding common stock;

• | a written statement that the stockholder or group of stockholders intends to continue to beneficially own more than 5% of our outstanding common stock through the date of the next annual meeting of our stockholders;

• | the name and record address of each stockholder submitting a recommendation for the director candidate, the written consent of each such stockholder and the director candidate to be publicly identified (including, in the case of the

23

director candidate, to be named in the company's proxy materials) and the written consent of the director candidate to serve as a member of our board of directors (and any committee of our board of directors to which the director candidate is assigned to serve by our board of directors) if elected;

• | a description of all arrangements or understandings between or among any of the stockholders or group of stockholders submitting the recommendation, the director candidate and any other person or persons (naming such person or persons) pursuant to which the submission of the recommendation is to be made by such stockholder or group of stockholders;

• | with respect to the director candidate, (1) his or her name, age, business and residential address and principal occupation or employment, (2) the number of shares of our common stock beneficially owned by him or her, (3) a resume or similar document detailing his or her personal and professional experiences and accomplishments, and (4) all other information relating to the candidate that would be required to be disclosed in a proxy statement or other filing made in connection with the solicitation of proxies for the election of directors pursuant to the Exchange Act, the rules of the Securities and Exchange Commission or the rules of the Nasdaq Stock Market; and

• | a written statement that each submitting stockholder and the director candidate shall make available to the nominating and corporate governance committee all information reasonably requested in connection with the committee's evaluation of the candidate.

The notice must be signed by each stockholder submitting the proposal and the director candidate. The notice must be sent to the following address by registered or certified mail: Kaiser Aluminum Corporation, Attn: Corporate Secretary (Nominating and Corporate Governance Committee), 27422 Portola Parkway, Suite 200, Foothill Ranch, California 92610-2831.
The nominating and corporate governance committee charter requires that all members of the nominating and corporate governance committee satisfy the general independence criteria. In addition, the members of the nominating and corporate governance committee must include at least one of the directors nominated by the USW.
Talent Development Committee
The talent development committee of our board of directors assists the board of directors in discharging its responsibilities relating to management succession planning and oversight of leadership and talent development. We recognize that over the long-term, our talent and culture provide competitive advantages. As such, we consider leadership and talent a priority throughout the company.
The talent development committee was formed in 2014 to review and evaluate (1) the succession planning for our executive officers, other than our CEO, whose succession is discussed routinely during board executive sessions, and (2) the leadership and development training of key employees with the potential to succeed our executive officers, including the progression and development of such key employees. The talent development committee meets with our CEO to review its observations and management’s criteria for evaluating the performance and advancement potential of those key employees and regularly reports its activities to our board of directors.
Board and Committee Meetings and Consents in 2019
During 2019, our board of directors held seven meetings and acted by unanimous written consent five times. In addition to meetings of our board of directors, directors attended meetings of committees of our board of directors. Each director attended at least 75% of the aggregate number of meetings that our board of directors held during the period he or she was a director in 2019 and that each committee on which he or she served held during the period he or she served on such committee in 2019.
Annual Meetings of Stockholders
Members of our board of directors are expected to make reasonable efforts to attend our annual meetings of stockholders. All of our directors then serving attended our 2019 annual meeting of stockholders.
Annual Performance Reviews
We conduct robust annual board and committee assessments using internal and/or external resources. Under our corporate governance guidelines, our board of directors is required to conduct an annual self-evaluation to determine whether our board of directors and its committees are functioning effectively. The charter for each committee of our board of directors also
24

requires each committee to annually evaluate its performance. The nominating and corporate governance committee reviews the annual evaluation process and modifies the process as it deems appropriate.
In addition to the evaluation performed by the nominating and corporate governance committee with respect to whether an incumbent director should be nominated for re-election to the board of directors upon expiration of such director's term, in 2019, our board of directors conducted an annual self-evaluation through the completion of an open-ended survey by each of our directors. The results from the survey were summarized and reviewed with the nominating and corporate governance committee and the full board. In addition, we meet with the USW not less than annually to discuss (i) our most recent assessment of strategic board skills, experience, attributes of all directors, (ii) desired strategic board skills, experience, attributes and priorities in the context of anticipated vacancies and upcoming elections and (iii) each board member nominated by the USW and contemplated future USW nominees in light of these considerations.
Stockholder Engagement
We value stockholder views and insights and believe that accountability to stockholders is an essential component of good governance. We engage in ongoing, proactive discussions of a variety of topics, including our strategy and performance, business operations, capital allocation, corporate governance and environmental matters, with significant stockholders throughout the year. Such discussions are held year-round and include our CEO and Chairman of the Board and/or other members of senior management. In addition to providing our perspective and seeking feedback on topics specific to our company, we invite discussion on any other topics or trends stockholders may wish to discuss with us. The feedback provided by stockholders is reported to the full board of directors. The board of directors reviews the feedback and determines whether additional discussion and actions are necessary by the full board or any board committees. In 2019, in addition to interactions regarding our financial performance, we engaged with stockholders representing approximately 60% of shares outstanding on matters relating to our long-term business strategy and performance, corporate governance, executive compensation and corporate responsibility. In addition, we utilize investor surveys to provide us with additional insight into the perceptions of our broader investor-base, across a wide range of topics. This information is also reviewed by members of our senior management and the full board of directors. The feedback from our stockholders continues to reflect that they are generally satisfied with our performance and the design of our executive compensation program.
25

Sustainable Value Creation
We manage our business for long-term success in a manner that is economically, environmentally and socially responsible.

Stock Ownership Guidelines and Securities Trading Policy
Our stock ownership guidelines require our non-employee directors to own company stock equal to six times their annual base retainer within five years of becoming a member of our board of directors. For purposes of measuring our non-employee directors' compliance with our stock ownership guidelines, restricted stock is valued at the closing price of our common stock on the grant date and all other shares of common stock purchased or acquired are valued at the purchase price of such shares. Currently, each of our non-employee directors satisfies the applicable stock ownership requirements under the stock ownership guidelines. Our stock ownership guidelines also apply to senior management. For additional information regarding our stock ownership guidelines, see "Executive Compensation - Stock Ownership Guidelines."
Our securities trading policy prohibits our directors and employees, including our named executive officers, from purchasing financial instruments to hedge or offset, or otherwise engaging in transactions designed to hedge or offset, decreases in the market value of our equity securities, whether granted as part of compensation to, or otherwise held directly or indirectly by, such director or employee. Prohibited transactions include short sales, options, puts, calls and derivative instruments such as swaps, forwards and futures. Our securities trading policy also prohibits our directors and employees, including our named executive officers, from buying our securities on margin (other than purchases where the related margin borrowings are effected solely for the purpose of paying the option exercise price upon the exercise of an option to purchase shares from the company, which are typically referred to as “cashless exercises”) or holding our securities in a margin account, and from pledging our securities as collateral for a loan or any other obligations.
Risks Arising from Compensation Policies and Practices
Our compensation policies and practices, discussed more fully below, are designed to create and maintain alignment between our employees and stockholders by rewarding employees, including our senior management, for achieving strategic goals that successfully drive our operations and enhance stockholder value and to preclude the taking of unreasonable risks through the use of incentive compensation that rewards decisions that result in strong performance in both the short- and long-term. We do not believe that our compensation policies and practices encourage decisions or actions which are likely to have a material adverse effect on our company. Our determination is based on, among other factors, the following:

• | Potential payouts under our incentive plans are capped, and overall variable compensation does not materially impact our financial results;

27

• | Our overall compensation is comprised of a mix of long- and short-term compensation which discourages short-term decisions that could be at the expense of long-term results;

• | A significant portion of the variable compensation is in the form of restricted stock units and performance shares with three-year vesting and performance periods, which ensure that three years of unvested grants are outstanding at any time and encourage decisions expected to create long-term value for our stockholders;

• | Underlying performance and results impacting our incentive compensation plans are subject to extensive review, verification and validation;

• | All of our incentive programs contain clawback provisions, which provide for the forfeiture of outstanding unvested awards and the return of vested awards;

• | Our short-term incentive plan and our performance shares require the attainment of threshold company performance levels before any payments are earned or performance shares vest; and

• | Our stock ownership guidelines require our board of directors and executive officers to retain significant equity interests in our company to ensure the ongoing alignment of executive officers and our stockholders.

Stockholder Communications with the Board of Directors
Our stockholders may communicate with our board of directors as a group or with the chair of the executive committee, audit committee, compensation committee or nominating and corporate governance committee by sending an email to boardofdirectors@kaiseraluminum.com, execchair@kaiseraluminum.com, auditchair@kaiseraluminum.com, compchair@kaiseraluminum.com, or nominatingchair@kaiseraluminum.com, respectively, or by writing to such group or person at Kaiser Aluminum Corporation, Attn: Corporate Secretary (Board of Directors), 27422 Portola Parkway, Suite 200, Foothill Ranch, California 92610-2831. Communications that are intended specifically for any other group of directors or for any individual director, such as the independent directors as a group or the Lead Independent Director, should be sent to the attention of our corporate secretary at the address above or via email to corpsecretary@kaiseraluminum.com and should clearly state the individual director or group of directors that is the intended recipient of the communication.
Our corporate secretary will review each communication and determine whether or not the communication is appropriate for delivery. Communications that, in the judgment of our corporate secretary, are clearly of a marketing nature, that advocate that our company engage in illegal activity, that do not reasonably relate to our company or our business or that are similarly inappropriate will not be furnished to the intended recipient. If, in the judgment of the corporate secretary, any communication pertains to an accounting matter, it will be forwarded to our compliance officer.
Communications that, in the judgment of our corporate secretary, are appropriate for delivery will, unless requiring immediate attention, be assembled and delivered to the intended recipients on a periodic basis, generally at or in advance of each regularly scheduled meeting of our board of directors. Any communication that, in the judgment of our corporate secretary, requires immediate attention will be promptly delivered. In no case will the corporate secretary provide anyone but a member of our board of directors with access to any such communication, except as noted above with respect to communications pertaining to accounting matters.

Overview of the Compensation Committee
The compensation committee of our board of directors is comprised entirely of independent directors. By design, members of the compensation committee also serve on other board committees, including the executive committee, the audit committee, the nominating and corporate governance committee and the talent development committee. We believe this structure helps coordinate the efforts of the respective committees. The compensation committee's primary duties and responsibilities are to establish and implement our compensation policies and programs for senior management. While the nominating and corporate governance committee has the responsibility to evaluate the overall performance of our CEO, the compensation committee coordinates with and assists the nominating and corporate governance committee in that evaluation.
The compensation committee has the authority under its charter to engage the services of outside advisors, experts and others to assist it. Pursuant to that authority, the compensation committee engaged Meridian to advise it on all matters related to compensation of our CEO and other members of senior management, including the other named executive officers.
The compensation committee meets formally and informally throughout the year. Informal meetings frequently occur when our directors are together for meetings of our full board of directors and telephonically at the request of one or more committee members. Our CEO, other members of our management and outside advisors may be invited to attend all or a portion of a compensation committee meeting depending on the nature of the agenda items; however, neither our CEO nor any other member of management votes on items before the compensation committee.
The compensation committee works with our senior management and Meridian to determine the agenda for its formal meetings and to prepare meeting materials. The compensation committee and our board of directors also solicit the views of our CEO on compensation matters, including, among others:

• | objectives for our compensation programs;

• | the structure of our compensation programs;

• | the role of our compensation programs in management succession planning; and

• | compensation of other members of senior management, including our other named executive officers.

Objectives of our Compensation Structure
Our compensation structure was developed to achieve the following objectives, which we believe are critical for enhancing stockholder value and to our long-term success and sustainability:

• | creating alignment between our senior management and our stockholders by rewarding our senior management for achieving strategic goals that successfully drive our operations and enhance our stockholder return;

• | attracting, motivating and retaining highly experienced executives vital to our short-term and long-term success, profitability and growth; and

• | correlating our senior management compensation with our actual short- and long-term performance.

Design of our 2019 Compensation Program
Our 2019 compensation program for our senior management, including our named executive officers, was designed to reinforce performance and accountability at the corporate, operational and individual levels through the use of:

• | a short-term annual cash incentive payable only if the performance threshold is met; and

• | an equity-based, long-term incentive consisting of (1) restricted stock units with three-year cliff vesting to promote senior management retention, and (2) performance shares, 60% of which vest, if at all, based on our TSR compared to a group of peer companies and 40% of which vest, if at all, based on our total controllable cost performance, each over a three-year performance period (2019 through 2021).

In addition to focusing on "pay for performance," our 2019 compensation program:
33

• | balanced short-term and long-term goals, with:

• | approximately 57% of our CEO's target total compensation being delivered through long-term incentives; and

• | approximately 37% to 52% of the target total compensation for our other named executive officers being delivered through long-term incentives;

• | delivered a mix of fixed and at-risk compensation directly related to our overall performance and the creation of stockholder value, with:

• | approximately 75% of the target compensation of our CEO and our President and COO being at-risk compensation payable only if certain corporate performance levels are achieved; and

• | approximately 55% to 68% of the target total compensation for our other named executive officers being at-risk compensation payable only if certain corporate performance levels are achieved;

• | provided compensation that is competitive with our compensation peer group recommended by the compensation committee's independent compensation consultant;

• | utilized equity-based awards, including performance shares that vest only if we achieve a certain relative TSR and cost performance, stock ownership guidelines and annual cash incentives linked to achievement of financial, corporate, operational and individual performance;

• | emphasized the importance of safety, quality, delivery and cost performance; and

• | utilized forfeiture provisions that can result in the loss of awards and resulting benefits if we determine that a recipient, including any of our named executive officers, has engaged in certain activities detrimental to us.

Periodically, but not less than annually, each element of compensation is reviewed and considered by the compensation committee and our board of directors both individually and collectively with the other elements of compensation to ensure that each element is consistent with the objectives of both our comprehensive compensation structure and that particular element of compensation. The compensation committee and our board of directors share suggestions or concerns identified in the course of that review with senior management and Meridian, who address the suggestions or concerns in a manner that is satisfactory to the compensation committee and our board of directors. This process occurs over a series of meetings of the compensation committee and our board of directors and executive sessions of the independent directors without members of management present.
In designing the overall compensation program and each individual element of compensation for senior management, including our named executive officers, the compensation committee considers the following factors, among others:

• | The external challenges to our near- and long-term ability to attract and retain strong senior management;

• | Each individual's contributions to our overall results;

• | Our historical and anticipated operating and financial performance compared with targeted goals; and

• | Our size and complexity compared with companies in our compensation peer group.

The compensation committee uses tally and other summary sheets that provide a summary of the compensation history of our CEO and those members of our senior management reporting to our CEO. These tally and information sheets include a historical summary of base salary, annual bonus and equity awards.
In reviewing and deliberating our 2019 compensation program, the compensation committee considered, among other things:

• | the company's key strategic initiatives, business plan and underlying assumptions;

• | the goal of maintaining alignment between our senior management and our stockholders through the use of short- and long-term, performance-based compensation;

34

• | the benefits of maintaining a consistent approach to compensation and the structure of our programs through business cycles;

• | the anticipated performance of the company's compensation programs based on the company's business plan and current financial position;

• | the economic conditions in the United States and abroad; and

• | stockholder feedback.

The review included discussions with Meridian and management regarding existing and contemplated market practices, as well as the structure and objectives of each component of our compensation program.
The compensation committee also reviews the compensation and benefit practices, as well as levels of pay, of a compensation peer group of companies. Working with Meridian, the compensation committee selects for inclusion in our compensation peer group companies that are determined to:
(1) be of a similar size;
(2) have positions of similar complexity and scope of responsibility; and/or
(3) compete with us for talent.
The compensation committee, working with the compensation consultant, reviews, evaluates and updates the compensation peer group, which includes companies in both similar and different industries, at least annually. For 2019, the compensation committee approved the following 34-company peer group with (1) market capitalizations ranging from $489 million to approximately $11.6 billion and a median market capitalization of approximately $2.2 billion and (2) revenues ranging from $736 million to approximately $3.7 billion and median revenue of approximately $1.7 billion:

Actuant Corp. | ITT Inc.
Briggs & Stratton Corp. | John Bean Technologies Corporation
Carpenter Technology Corp. | Kennamental Inc.
Century Aluminum Co. | Lydall, Inc.
Chart Industries, Inc. | Mueller Industries, Inc.
Clearwater Paper Corp. | Mueller Water Products, Inc.
Cleveland-Cliffs Inc. | Nordson Corp.
Comfort Systems USA, Inc. | P.H. Glatfelter Co.
Donaldson Company, Inc. | SPX FLOW, Inc.
EnPro Industries, Inc. | Standex International Corp.
ESCO Technologies Inc. | SunCoke Energy, Inc.
Franklin Electric Co., Inc. | The Timken Company
Global Brass and Copper Holdings, Inc. | Timken Steel Corporation
Graco Inc. | TriMas Corp.
Harsco Corp. | Watts Water Technologies, Inc.
Hillenbrand, Inc. | Woodward, Inc.
IDEX Corp. | Worthington Industries, Inc.

Our market capitalization as of December 31, 2019 and revenues for 2019 were $1.8 billion and $1.5 billion, respectively. Due to the differences in size among the companies in our peer group, Meridian uses a regression analysis to adjust survey data results based on our revenue as compared to the revenue of other companies in our peer group. Importantly, the compensation committee recognizes that we compete for talent with companies much larger than those included in our compensation peer group. These larger companies, including Aleris, Arconic, Constellium and Sapa, aggressively recruit the most highly qualified talent in critical functions. As a result, to attract and retain talent, the compensation committee may from time to time determine that it is in the best interests of our company and our stockholders to provide compensation packages that deviate from targeted pay levels. For 2019, in addition to data obtained from publicly disclosed proxy statements, Meridian also provided data obtained from Equilar Executive Compensation Survey. We did not select the constituent companies comprising this survey group, however, and the component companies’ identities were not a material factor in the applicable compensation analysis.

Each compensation element is discussed in detail below.
2019 base salary
The compensation committee annually reviews base salaries for our CEO and other executive officers, including our other named executive officers, and determines whether a change is appropriate. In reviewing base salaries, the compensation committee considers factors, including, among others:

• | level and scope of responsibility;

• | prior experience;

• | base salaries paid for comparable positions by our compensation peer group; and

• | the relationship among base salaries paid within our company.

Our intent is to fix base salaries at levels consistent with the design of our overall compensation program for the particular year. In 2019, the compensation committee, based on Mr. Hockema's recommendation, did not increase the base salaries of our named executive officers, except for Messrs. Rinkenberger and West, and instead allocated a total increase to their total target compensation of 3% to their short- and long-term incentive compensation targets. Mr. Rinkenberger retired in March 2019 and did not receive an adjustment to his compensation. Mr. West received an adjustment to his total compensation, including his base salary, principally to reflect the increased responsibilities associated with his promotion to Chief Financial Officer. Base salaries for our named executive officers in 2019 were as follows:
36

Name | 2019 Base Salary
Jack A. Hockema | $ | 915,000 |  |
Keith A. Harvey | $ | 552,000 |  |
John M. Donnan | $ | 438,800 |  |
Neal West* | $ | 425,000 |  |
Raymond D. Parkinson* | $ | 363,100 |  |
Daniel J. Rinkenberger** | $ | 468,000 |  |

___________________________
* Effective April 1, 2019.
** Mr. Rinkenberger retired in March 2019.
2019 short-term incentive
The table below summarizes the performance metrics under our 2019 short-term incentive plan:

Incentive Program | Performance Metric | Weighting | Modifier* | Impact on Multiplier
Short-Term Incentive Plan | Adjusted EBITDA | 100% | Safety (TCIR & LCIR) | +/- 10%
|  |  | Quality | +/- 10%
|  |  | Delivery | +/- 10%
|  |  | Cost | +/- 20%
|  |  | Individual | +/- 100%

_______________
* The safety modifier is measured using our total case incident rate ("TCIR") and lost-time case incident rate ("LCIR"), the quality modifier is measured using our no-fault claim rate, the delivery modifier is measured by our on-time delivery rate, and the cost modifier is measured by our manufacturing efficiency. As noted, the individual modifier is discretionary and only used in exceptional and rare instances approved by the compensation committee.
The following summarizes our performance against the metrics under our 2019 short-term incentive plan:

Adjusted EBITDA |  |

_______________
* The targets are based on the Adjusted EBITDA required to achieve the designated return on net assets (excluding cash) using our adjusted pre-tax operating income. As noted, increasing net assets and depreciation raise the year-over-year Adjusted EBITDA targets. As previously noted, while we achieved strong quality performance in 2019, our safety, on-time delivery and cost performance lagged and did not meet our demanding expectations and requirements, resulting in +10%, -1%, -12% and -25% modifiers, respectively, and an overall reduction of Adjusted EBITDA multiplier of 1.24 to a final multiplier of 0.96. The safety modifier was determined based on our TCIR and LCIR performance, the quality modifier was determined based on our no-fault claim performance, the delivery modifier was determined based on our on-time delivery performance, and the cost modifier was determined based on our manufacturing efficiency performance.
37

FEATURES
Ÿ | Pay for performance
Ÿ | Adjusted EBITDA target determined based on return on net assets (excluding cash) using our adjusted pre-tax operating income
Ÿ | Modifiers for safety, quality, delivery and cost performance establishing a strong linkage to strategic non-financial results
Ÿ | In exceptional and rare instances approved by our compensation committee, individual adjustment up to plus or minus 100% based on exceptional performance, including individual, facility and/or functional area performance
Ÿ | No payout unless we:
| (1) | achieve the threshold Adjusted EBITDA goal
| (2) | generate positive adjusted net income
Ÿ | Maximum payout capped at three times the target
Ÿ | Rigorous financial performance goals - target increases with investments and increasingly higher net assets and depreciation

Our 2019 short-term incentive plan, which we refer to as our 2019 STI Plan, was an annual cash incentive plan designed to reward participants for achieving certain Adjusted EBITDA performance goals determined based on designated returns on our adjusted net assets (excluding cash) using our adjusted pre-tax operating income. The structure, terms and objectives of the 2019 STI Plan were generally consistent with those of the short-term incentive plan approved by the compensation committee in 2018, except for the annual increase of the Adjusted EBITDA targets. Consistent with the short-term incentive plan approved by the compensation committee in 2018, our 2019 STI Plan also included modifiers for safety, quality, delivery and cost performance and permitted, subject to the maximum payout opportunity described below, adjustments to individual payouts, in exceptional and rare instances, up to plus or minus 100%, based on actual performance, including individual, facility and/or functional area performance. Individuals not meeting individual performance goals could receive a reduced, or even no, payout and individuals meeting or exceeding individual performance goals could receive increased payouts; provided, however, that no increase could exceed the maximum payout opportunity of three times the target.
Consistent with our objective of aligning senior management and our stockholders by rewarding our senior management for achieving strategic goals that successfully drive our operations and enhance our stockholder value, our 2019 STI Plan provided that performance in excess of the threshold level would result in an increase in payouts up to the maximum payout opportunity. Under our 2019 STI Plan, potential payouts between the threshold and target levels and between the target and maximum levels were linearly interpolated.
Emphasizing the value we place on employee safety, our product quality, our relationships with our customers, manufacturing efficiency and individual accountability, in addition to financial performance, our 2019 STI Plan took into consideration: corporate safety performance, as measured by TCIR and LCIR; quality performance, as measured by our no-fault claim rate; delivery performance, as measured by our on-time delivery rate; cost performance, as measured by manufacturing costs compared to manufacturing costs in our business plan; and individual performance. Under our 2019 STI Plan, subject to the maximum payout, the award multiplier resulting from actual 2019 Adjusted EBITDA would be adjusted for safety, quality and delivery performance above or below the applicable threshold, each of which could increase or decrease the award multiplier by up to 10%, and for cost performance above or below the applicable threshold, which could increase or decrease the award multiplier by up to 20%. The final award may be increased or decreased by up to 100% based on individual performance in exceptional and rare circumstances.
The table below sets forth the possible payouts that could have been earned by our named executive officers at each performance level and the actual amounts earned by them under the 2019 STI Plan.

Name |  | Below Threshold |  | Threshold |  | Target |  | Maximum |  | Actual
Jack A. Hockema |  | — |  | $ | 361,500 |  |  |  | $ | 723,000 |  |  |  | $ | 2,169,000 |  |  |  | $ | 692,634 |  |

The Adjusted EBITDA targets under our short- term incentive plan reflect the Adjusted EBITDA required to achieve 7.5%, 15% and 35% returns on our net assets (excluding cash) based on adjusted pre-tax operating income at the threshold, target and maximum payout levels. As we have continued to invest in our business, our net assets and depreciation have continued to grow and, as a result, the Adjusted EBITDA targets have continued to increase each year. To that end, our Adjusted EBITDA performance at the target level increased 12% from 2018 to 2019. |  |
The table on the right illustrates our annual Adjusted EBITDA performance multiplier for the last three years under our short-term incentive plans before the application of modifiers. See Appendix A to this Proxy Statement for reconciliations of GAAP to non-GAAP measures. |

The Adjusted EBITDA Multiplier under our 2019 Short-Term Incentive Plan is the lowest in the last three years despite our record Adjusted EBITDA performance due to our annually increased Adjusted EBITDA targets. After the application of modifiers, the final multipliers under our short-term incentive plan for 2017, 2018, and 2019 were 1.51x, 1.18x and 0.96x, respectively, each reflecting the impact of our performance against demanding modifiers.
2019-2021 Long-term incentives
The table below summarizes the performance metrics under our 2019-2021 long-term incentive plan:

Incentive Program | Performance Metric | Weighting
Long-Term Incentive Plan | Total Controllable Cost | 40%
| TSR | 60%

The following summarizes metrics under our 2019-2021 long-term incentive plan:

Relative TSR* |
Controllable Cost** |

_______________
* Relative TSR is against companies comprising the S&P 600 SmallCap Materials Sector Index. Payout capped at target if TSR is negative.
39

FEATURES
Ÿ | Three-year performance period (2019-2021)
Ÿ | Includes retention features by utilizing time-vested restricted stock units
Ÿ | Pay for performance by utilizing performance shares subject to demanding metrics
Ÿ | Performance metrics:
| (1) | 40% based on controllable cost
| (2) | 60% based on relative TSR
Ÿ | Payout for relative TSR performance is capped at target if TSR is negative
Ÿ | Payout at target for controllable cost performance only if we completely offset underlying inflation
Ÿ | No windfall upon a change in control for performance shares - only shares earned based on performance through the date of the change in control will vest

We believe that consistent execution of our strategy over multi-year periods will lead to an increase in our stockholder return. We use equity awards to provide our named executive officers with an incentive to focus on long-term stockholder value creation. Our long-term incentive program for 2019 through 2021, which we refer to as our 2019 - 2021 LTI Program, for key employees, including our named executive officers, was approved by the compensation committee on March 5, 2019, and the structure, terms and objectives of the 2019 - 2021 LTI Program were generally consistent with those of the long-term incentive plan approved by the compensation committee in 2018, except for the elimination of EVA as a performance metric to increase the weighting of the TSR performance metric under the 2019 - 2021 LTI Program.
Since 2014, we have implemented long-term incentive programs based on TSR. In 2016, we added cost as a performance metric. Our 2019 - 2021 LTI Program was designed to "pay-for-performance" and to include retention features by rewarding participants with (1) time-vested restricted stock units and (2) performance shares, 60% of which that vest only if a certain TSR performance is achieved and 40% of which that vest only if a certain controllable cost performance is achieved, each over the 2019 through 2021 performance period.
Our 2019 - 2021 LTI Program provides, with respect to the restricted stock units issued to members of senior management, including our named executive officers, that, subject to limited exceptions, such units will vest on March 5, 2022. Each restricted stock unit that becomes vested entitles the participant to receive one share of our common stock.
The 2019 - 2021 LTI Program provides, with respect to the performance shares:
•a threshold performance level up to which no performance shares will vest or be earned;
•a target performance level at which the target number of performance shares will vest and be earned;

• | a maximum performance level at or above which the maximum number of performance shares (equal to two times the target number of performance shares) will vest and be earned; and

• | pro rata vesting between the threshold and maximum performance levels.

For 60% of the performance shares granted under our 2019 - 2021 LTI Program, the payout will be determined based on our TSR relative to the TSR of our peer companies in the S&P SmallCap 600 Materials Index as follows:

Percentile Ranking |  | Multiplier
< 25th |  | 0.0x
25th |  | 0.5x
50th |  | 1.0x
75th |  | 1.5x
≥ 90th |  | 2.0x

In considering constituents for the S&P SmallCap 600, S&P Dow Jones Indices looks for companies (1) with market capitalizations of between $450 million and $2.1 billion, (2) meeting certain float requirements, (3) with a U.S. domicile, (4) required to file annual reports with the SEC, and (5) listed on a major U.S. exchange, among other factors. The materials sector includes companies that manufacture chemicals, construction materials, glass, paper, forest products and related packaging products, and metals, minerals and mining companies.
40

For 40% of the performance shares granted under our 2019 - 2021 LTI Program, the payout will be determined based on our controllable cost performance as follows:

• | there is no payout under the controllable cost performance metric if the annualized controllable cost increase is equal to or greater than 2% after offsetting underlying inflation;

• | the performance required for the target payout under the controllable cost performance metric is an annualized controllable cost increase at 0% after offsetting underlying inflation; and

• | the performance required for the maximum payout under the controllable cost performance metric is an annualized controllable cost reduction equal to or greater than 2% after offsetting underlying inflation.

Controllable costs are generally defined as our variable conversion costs which adjust with our product volume and mix plus corporate and plant overhead. Controllable costs also (1) include benefits because we believe that management is required to take actions to influence benefit costs over the performance period and (2) exclude, among other things, major maintenance, research and development and enterprise resource planning costs to ensure that we continue to invest in the future of our company.
The compensation committee determined that each named executive officer, with the exception of Messrs. Hockema and Harvey, should receive time-based restricted stock units having an economic value equal to 50% of his target monetary value and a target number of performance shares having an economic value equal to 50% of his target monetary value. As provided by Mr. Hockema's employment agreement and consistent with the foregoing objectives, Mr. Hockema received time-based restricted stock units having an economic value equal to 36% of his target monetary value and a target number of performance shares having an economic value equal to 64% of his target monetary value. Mr. Harvey received time-based restricted stock units having an economic value equal to 33% of his target monetary value and a target number of performance shares having an economic value equal to 67% of his target monetary value.
The table below sets forth the target monetary value under our 2019 - 2021 LTI Program and the number of restricted stock units and performance shares granted to our named executive officers during 2019:

Name (1) |  | Target Monetary Value |  | Number of Restricted Stock Units (2) |  | Number of Performance Shares (at Target) (3)
Jack A. Hockema |  | $ | 2,204,000 |  |  |  | 8,488 |  |  |  | 18,024 |  |
Keith A. Harvey |  | $ | 1,133,000 |  |  |  | 4,000 |  |  |  | 9,699 |  |
John M. Donnan |  | $ | 602,600 |  |  |  | 3,223 |  |  |  | 3,849 |  |
Neal E. West |  | $ | 575,000 |  |  |  | 3,075 |  |  |  | 3,673 |  |
Ray D. Parkinson |  | $ | 293,600 |  |  |  | 1,570 |  |  |  | 1,875 |  |

____________

(1) | Mr. Rinkenberger retired in March 2019 and did not participate in the 2019-2021 LTI Program.

(2) | The restricted stock units granted will vest on March 5, 2022 or earlier if the named executive officer's employment terminates as a result of death or disability or in the event of a change in control. If the named executive officer’s employment is terminated by us without cause or the named executive officer’s employment is terminated by him for good reason, in either case before March 5, 2022, the restricted stock units will remain outstanding and vest on March 5, 2022 (or earlier in the event of his death or disability or a change in control). If Mr. Hockema's employment terminates before March 5, 2022 as a result of his retirement, a prorated portion of such restricted stock units, determined based on the actual days of his employment during the restriction period, will remain outstanding and vest on March 5, 2022 (or earlier in the event of his death or disability or a change in control). The number of restricted stock units granted was calculated by dividing (A) the applicable percentage (i.e., 36% and 33% for Messrs. Hockema and Harvey, respectively, and 50% for the other named executive officers) of the target monetary value by (B) an amount equal to (i) the average of the closing prices of our company's common stock for the 20 trading days prior to the grant date, which was $105.65 per share, minus (ii) 11.53% of such grant date value of $105.65, which represents the discount factor provided by Meridian to reflect the design characteristics, including the vesting period, of the restricted stock units.

(3) | The table below sets forth the number of performance shares that will vest and be earned for each of Messrs. Hockema, Harvey, Donnan West and Parkinson under our 2019 - 2021 LTI Program at each performance level:

41

Name |  | Below Threshold |  | Threshold |  | Target |  | Maximum
Jack A. Hockema |  | — |  | 9,012 |  |  |  | 18,024 |  |  |  | 36,048 |  |
Keith A. Harvey |  | — |  | 4,849 |  |  |  | 9,699 |  |  |  | 19,398 |  |
John M. Donnan |  | — |  | 1,924 |  |  |  | 3,849 |  |  |  | 7,698 |  |
Neal E. West |  | — |  | 1,836 |  |  |  | 3,673 |  |  |  | 7,346 |  |
Ray D. Parkinson |  | — |  | 937 |  |  |  | 1,875 |  |  |  | 3,750 |  |

The number of performance shares, if any, earned based on the level of performance achieved during the three-year performance period will vest on the later to occur of March 5, 2022 and the date on which the compensation committee certifies the performance level achieved during the three-year performance period, which shall be no later than March 15, 2022. If, prior to December 31, 2021, the named executive officer's employment terminates as a result of death or disability, the target number of performance shares will vest and be earned. If, prior to the vesting date, the named executive officer's employment is terminated by us without cause or is voluntarily terminated by him for good reason, the performance shares granted to him will remain outstanding and the number of performance shares, if any, earned will be determined based on the performance level achieved during the three-year performance period. If, prior to December 31, 2021, a change in control occurs, the performance shares granted to him will vest and the number of performance shares, if any, earned will be determined based on the performance level achieved during the performance period through the change in control date. If, prior to the vesting date, Mr. Hockema's employment terminates as a result of his retirement, the performance shares granted to him will remain outstanding and the number of performance shares, if any, earned will be determined based on the performance level achieved during the performance period and prorated based on the actual days of his employment during the performance period.
The threshold, target and maximum number of performance shares that may be earned, if at all, in 2022 under our 2019-2021 LTI Program are determined as follows:

• | the threshold number of performance shares reflects that no performance shares will be earned in 2022 under our 2019-2021 LTI Program unless our company's performance meets or exceeds the applicable threshold performance required over the 2019 through 2021 performance period;

• | the target number of performance shares was calculated by dividing (A) the applicable percentage (i.e., 64% and 67% for Messrs. Hockema and Harvey, respectively, and 50% for the other named executive officers) of the target monetary value by (B) an amount equal to (i) the average of the closing prices of our company's common stock for the 20 trading days prior to the grant date, which was $105.65 per share, minus (ii) 25.93% of such grant date value of $105.65, which represents the discount factor provided by Meridian in connection with the calculation of the economic value of the performance shares for purposes of determining the number of performance shares to be granted on the grant date; and

• | the maximum number of performance shares for each metric is approximately twice the target number of performance shares for that metric.

Upon a change in control, all the restricted stock units granted to the executives will vest, however the number of performance shares earned, if any, will be determined based on the performance level achieved against the underlying metrics applicable to the outstanding performance shares during the performance period through the date of the change in control ensuring that our named executive officers will only be rewarded for performance supporting strategic goals that successfully drive our operations and enhance our stockholder returns. We believe this structure (1) aligns the interests of our named executive officers with our stockholders, and (2) drives the performance required to meet our strategic initiatives and enhance stockholder returns, particularly when considering that the performance shares issued to our named executive officers have an economic value equal to at least 50% of each named executive officer's long-term incentive target (65% and 67% for Messrs. Hockema and Harvey, respectively), and that the performance shares earned, if any, upon a change in control will only be earned if the required performance level is achieved.

Results for 2017-2019 Performance Period

Relative TSR* |  |
Controllable Cost** |
EVA*** |

_______________
* Relative TSR is against companies comprising the S&P 600 SmallCap Materials Sector Index.
** There was no payout under the EVA performance metric as we did not achieve above threshold EVA performance.
On March 5, 2020, the three-year vesting period applicable to the grant of restricted stock under our long-term incentive program for 2017 through 2019, which we refer to as our 2017 - 2019 LTI Program, ended and the shares vested in accordance with the terms of the underlying grant. In addition, in early 2020 our compensation committee determined that 111% of the target performance shares granted under our 2017 - 2019 LTI Program had been earned based on our performance over the 2017 through 2019 performance period. The remaining performance shares granted under our 2017 - 2019 LTI Program were forfeited.
The payout under the 2017-2019 equity performance awards was based 40% on our TSR performance relative to the TSR performance of our peers in the S&P SmallCap 600 Materials Index, 40% on our total controllable cost performance, and 20% on our EVA performance. Our TSR is calculated based on the return of the 20-trading-day average closing prices between the beginning and the end of the applicable performance period, using the formula below. The average prices are based upon daily asset values, which represent adjusted stock prices for dividends reinvested throughout the period.

TSR = | (Ending Average – Beginning Average)
Beginning Average

The calculation for the 2017 to 2019 TSR is as follows:

TSR = | $119.96 – $81.30 | = 47.55%
$81.30

The beginning average price of $81.30 is based upon the 20-trading-day average closing stock prices of our common stock, assuming all dividends are reinvested as of the ex-dividend date, from December 2, 2016 to December 30, 2016. The ending average price of $119.96 is based upon the 20-trading-day average closing stock prices of our common stock, assuming all dividends are reinvested as of the ex-dividend date, from December 3, 2019 to December 31, 2019. We paid out $6.60 per share of dividends during the 2017 to 2019 performance period.
43

Our TSR of 47.55% for the 2017 to 2019 performance period ranked #5 out of the 33 companies in the S&P SmallCap 600 Materials Index, or the 88th percentile, resulting in a payout of 192% of the target performance shares with the relative TSR performance metric.
The chart below illustrates the performance share award payouts based on our relative TSR performance for the 2015-2017, 2016-2018 and 2017-2019 long-term incentive programs:

| Performance shares earned, if any, are based on our TSR over the underlying three year performance period compared to the other companies comprising the S&P 600 SmallCap Materials Sector Index.
The beginning and ending stock prices used to determine our TSR are calculated using the 20-trading day average preceding the beginning and end of the performance period.
The performance share multiplier is determined by using straight line interpolation based on our TSR percentile ranking within our comparison group based on the table to the right: | Percentile Ranking |  | Multiplier
< 25th |  | 0.0x
25th |  | 0.5x
50th |  | 1.0x
75th |  | 1.5x
> 90th |  | 2.0x

For the 2017 to 2019 performance period, we achieved a total controllable cost reduction of 1% in excess of underlying inflation compared to the baseline 2016 controllable cost, resulting in a payout of 85% of the target performance shares with the controllable cost performance metric.
For the remaining 20% of the performance shares granted under the 2017-2019 LTI Program, the payout was determined based on our EVA performance, calculated as the excess of our adjusted pre-tax operating income as reported in our public filings in excess of an amount equal to 15% of our net assets. We believe that positive EVA, while significantly impacted by market conditions, requires exceptional performance and incentivizes capital efficiency and value creation, as well as increasingly higher targets as a result of our investments. As previously discussed, we did not achieve the threshold performance required for payout of the performance shares with the EVA performance metric.
Retirement benefits
We no longer maintain a defined benefit pension plan or retiree medical program that covers members of senior management. Retirement benefits to our senior management, including our named executive officers, are currently provided through a defined contribution retirement program consisting of the following two principal plans:

• | the Kaiser Aluminum Savings and Investment Plan, a tax-qualified profit-sharing and 401(k) plan (which we refer to as our Savings Plan); and

• | a nonqualified and unsecured deferred compensation plan (which we refer to as our Restoration Plan) intended to restore benefits that would be payable to designated participants in our Savings Plan but for the limitations on benefit accruals and payments imposed by the Code.

The defined contribution retirement program has the following three primary components, which are discussed more fully below:

• | A company match of the employee's pre-tax deferrals under our Savings Plan;

44

• | A company contribution to the employee's account under our Savings Plan; and

• | A company contribution to the employee's account under our Restoration Plan.

Under the terms of our Restoration Plan, cash balances are maintained in a "rabbi trust" where they remain subject to the claims of our creditors and are otherwise invested in funds designated by each individual from a menu of possible investments. In addition, the cash balances maintained in the rabbi trust are forfeited if the individual is terminated for cause.
The compensation committee believes the Savings Plan and the Restoration Plan support the objectives of our comprehensive compensation structure, including the ability to attract and retain senior and experienced mid- to late-career executives for critical positions within our organization. Each of these plans is discussed more fully below.
Perquisites
Our use of perquisites as an element of compensation is very limited and largely based on business-related entertainment needs. We do not view perquisites as a significant element of our comprehensive compensation structure but do believe that they can be used in conjunction with base salary to attract, motivate and retain individuals in a competitive environment. During 2019, all of our named executive officers received a vehicle allowance. Messrs. Donnan and Harvey were also reimbursed for dues for club memberships.
Consideration of the 2019 Advisory Vote to Approve Named Executive Officer Compensation
We provide our stockholders with the opportunity to cast an annual vote to approve our named executive officer compensation. At our 2019 annual meeting of stockholders, approximately 84% of shares of our common stock voted on the proposal were voted to approve the compensation of our named executive officers as disclosed in the proxy statement relating to such meeting. The compensation committee has considered the outcome of the vote on executive compensation at our 2019 annual meeting of stockholders, as well as the feedback received through our stockholder engagement, and believes they affirm our stockholders' support of our overall approach to executive compensation. The compensation committee expects to continue to consider the outcome of the annual vote to approve named executive officer compensation when making future compensation decisions for the named executive officers.
Stock Ownership Guidelines
In order to further align the interests of senior management, including our named executive officers, with those of our stockholders, we have stock ownership guidelines, which are set forth in our corporate governance guidelines. Under those guidelines, members of our senior management are expected to hold common stock having a value equal to a multiple of their base salary as determined by their position. The guidelines provide for a target multiple of six times base salary for our CEO and President and COO and three times base salary for the other named executive officers. Each member of senior management covered by our stock ownership guidelines is expected to retain at least 75% of the net shares resulting from equity compensation awards until he or she achieves the applicable ownership level required by the stock ownership guidelines. The ownership guidelines are expected to be met within five years. Each of our named executive officers has satisfied the applicable stock ownership requirements under the stock ownership guidelines.
For purposes of measuring compliance with our stock ownership guidelines (1) restricted stock and restricted stock units are valued at the closing price of the company's common stock on the grant date, (2) performance shares are valued using the target number of performance shares and the closing price of our common stock on the grant date, and (3) all other shares of common stock purchased or acquired by members of our senior management are valued at the purchase price of the shares.
Securities Trading Policy
Our securities trading policy prohibits our directors and employees, including our named executive officers, from purchasing financial instruments to hedge or offset, or otherwise engaging in transactions designed to hedge or offset, decreases in the market value of our equity securities, whether granted as part of compensation to, or otherwise held directly or indirectly by, such director or employee. Prohibited transactions include short sales, options, puts, calls and derivative instruments such as swaps, forwards and futures. Our securities trading policy also prohibits our directors and employees, including our named executive officers, from buying our securities on margin (other than purchases where the related margin borrowings are effected solely for the purpose of paying the option exercise price upon the exercise of an option to purchase shares from the company, which are typically referred to as “cashless exercises”) or holding our securities in a margin account, and from pledging our securities as collateral for a loan or any other obligations.

Employment Contracts, Termination of Employment Arrangements and Change-in-Control Arrangements
As discussed more fully below, on September 17, 2019, we entered into an amended and restated employment agreement with Mr. Hockema to (i) extend the term of the existing employment agreement to July 15, 2022, (ii) maintain continuity, and (iii) facilitate the our ability to implement a chief executive officer succession plan should the our board of directors choose to do so during the extended term without triggering severance payments under the amended agreement. More specifically, pursuant to the amended agreement, if prior to July 15, 2022 a successor chief executive officer is appointed pursuant to a board-approved succession plan, the term of the amended agreement will automatically end upon such appointment, so long as (a) the appointment occurs after July 15, 2020 and prior to a change in control (as defined in the amended agreement) and (b) immediately following the appointment, Mr. Hockema continues to hold the office of Chairman or is named Executive Chairman and receives annual compensation for his service in either of those capacities at least equivalent to the annual retainer and board meeting fees payable to our Lead Independent Director. As noted, in such event, Mr. Hockema would not be entitled to any severance payments under the amended agreement.
The compensation committee, working with Meridian, determined that the negotiated terms of the amended agreement were consistent with market practice and in the best interests of our company and stockholders.
Also, as discussed more fully below, certain members of senior management, including four of our named executive officers, continue to have benefits related to terminations of employment in connection with a change in control, by us without cause and by the named executive officer with good reason. These protections limit our ability to downwardly adjust certain aspects of compensation, including base salaries and target incentive compensation, without triggering the ability of the affected named executive officer to receive termination benefits in connection with a change in control.
2019 Summary Compensation Table
The table below sets forth information regarding compensation for our named executive officers: (1) Jack A. Hockema, our CEO and Chairman of the Board (our principal executive officer); (2) Neal West, our Senior Vice President and Chief Financial Officer (our principal financial officer), (3) Daniel J. Rinkenberger, our former Executive Vice President and Chief Financial Officer (our principal financial officer during a portion of 2019); and (4) each of Keith A. Harvey, John M. Donnan, and Raymond D. Parkinson, our three other most highly compensated executive officers (based on total compensation for 2019). Mr. Rinkenberger retired from our company in March 2019.

____________

(1) | Reflects the aggregate grant date fair value of restricted stock units and performance share awards to our named executive officers determined in accordance with Financial Accounting Standards Board Accounting Standard Code Topic 718 (referred to herein as ASC Topic 718), without regard to potential forfeiture. The aggregate grant date fair value of the performance shares awards reflected in this table has been determined assuming the probable outcome of the performance condition on the date of the grant and without adjustment for actual performance during the period and, for performance shares with relative TSR as the performance metric, using a Monte Carlo simulation of future stock prices of our company and our peer companies on the S&P 600 SmallCap Materials Sector Index. The aggregate grant date fair value of the 2019 performance share awards determined assuming the probable outcome of the performance conditions and assuming an outcome of the performance conditions at the maximum level are as follows:

|  |  |  | Aggregate Grant Date Fair Value
Name |  | Year |  | At Probable Performance |  | At Maximum Performance

(1) | For information regarding the assumptions made in the valuation of restricted stock units and performance share awards with respect to our 2019 fiscal year, see Note 7 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.

(2) | Reflects payments earned under our 2019 STI Plan.

(3) | Reflects the aggregate change in actuarial present value of the named executive officer's accumulated benefit under a defined pension benefit plan previously maintained by us for our salaried employees, which we refer to as our Old Pension Plan, during the applicable fiscal year, calculated by (a) assuming mortality according to the RP-2014 White Collar Healthy Annuitant mortality table, adjusted to 2006 and then projected forward with Scale MP-2016 as of December 31, 2018 and the RP-2012 White Collar Healthy Annuitant mortality table, adjusted to 2006, and then projected forward with Scale MP-2019 as of December 31, 2019 and (b) applying a discount rate of 3.20%, 3.90% and 2.95% per annum for 2017, 2018 and 2019, respectively, to determine the actuarial present value of the accumulated benefit at December 31 of the preceding year and a discount rate of 3.60%, 3.20% and 3.90% per annum, respectively, to determine the actuarial present value of the accumulated benefit at December 31 of the applicable year. Effective December 17, 2003, the Pension Benefit Guaranty Corporation, or PBGC, terminated and effectively assumed responsibility for making benefit payments in respect of our Old Pension Plan, whereupon all benefit accruals under the Old Pension Plan ceased and benefits available thereunder to certain salaried employees, including Mr. Hockema, were significantly reduced due to the limitations on benefits payable by the PBGC. Above-market or preferential earnings are not available under our Restoration Plan, which is our only plan or arrangement pursuant to which compensation may be deferred on a basis that is not tax-qualified, or any of our other benefit plans.

(4) | Includes (a) contributions made or to be made by us under our Savings Plan, (b) contributions made or to be made by us under our Restoration Plan (which is intended to restore the benefit of contributions that we would have otherwise paid to participants under our Savings Plan but for limitations imposed by the Code), (c) dividend and dividend equivalent payments which were not factored into the reported grant date fair value of the restricted stock unit and performance share awards, and (d) the costs to us of perquisites and other personal benefits. See the table set forth under "- All Other Compensation" below for information regarding each such component.

As reflected in the table above, the base salary received by each of our named executive officers, other than Mr. Rinkenberger, as a percentage of their respective total compensation was as follows:

• | For 2019 Mr. Hockema, 17.4%; Mr. Harvey, 17.7%; Mr. Donnan, 24.5%; Mr. West, 26.4%; and Dr. Parkinson, 34.2%;

• | For 2018, Mr. Hockema, 16.9%; Mr. Harvey, 17.6%; and Mr. Donnan, 24.6%.

• | For 2017 Mr. Hockema, 15.9%; Mr. Harvey, 9.2%; and Mr. Donnan, 22.1%.

Mr. Rinkenberger retired in March 2019 and did not participate in any of our 2019 incentive plans.

(2) | Reflects the number of performance shares that generally will become vested and earned for each of the named executive officers under our 2019 - 2021 LTI Program in 2022 at the threshold, target and maximum performance levels. No performance shares will vest under the 2019 - 2021 LTI Program if our company's performance does not reach the threshold performance required during the three-year performance period.

(3) | Reflects the aggregate grant date fair value of restricted stock units and performance share awards to our named executive officers determined in accordance with ASC Topic 718, without regard to potential forfeiture. The aggregate grant date fair value of the performance share awards reflected in this table has been determined assuming the probable outcome of the performance condition on the date of the grant and without adjustment for actual performance during the period and, for performance shares with relative TSR as the performance metric, using a Monte Carlo simulation of future stock prices of our company and our peer companies on the S&P 600 SmallCap Materials Index.

(4) | Reflects the number of restricted stock units received by the named executive officer pursuant to awards granted effective March 5, 2019.

Employment-Related Agreements and Certain Employee Benefit Plans
Employment Agreement with Jack A. Hockema
On July 6, 2006, we entered into an employment agreement with Jack A. Hockema, pursuant to which Mr. Hockema continued his duties as our President and CEO. On November 9, 2010, we entered into an amended and restated employment agreement with Mr. Hockema to extend the term of the existing employment agreement from July 5, 2012 through July 6, 2015, eliminate the automatic renewal provision, eliminate our obligation to make excise tax gross-up payments to Mr. Hockema, and modify his long-term incentive compensation to increase the portion of such compensation in the form of performance shares. The agreement was amended and restated on March 5, 2014, primarily to extend the term of the existing employment agreement through December 31, 2016 and modify the calculation of any prorated payment of Mr. Hockema's annual short-term incentive compensation upon the termination of his employment prior to the last day of the applicable fiscal year so that such calculation is based on actual, rather than target, performance, and was amended on March 31, 2014 to permit his 2014 long-term incentive award to provide for prorated payment based on the actual number of days of his employment during the applicable restricted or performance period, rather than full payment, in the event of his retirement prior to the end of the applicable restricted or performance period. On each of December 31, 2015 and July 15, 2017, the agreement was amended and restated to extend the term through December 31, 2018 and July 15, 2020, respectively. On September 17, 2019, the agreement was again amended and restated to extend the term of the existing employment agreement through July 15, 2022.
The terms of Mr. Hockema's amended and restated employment agreement provide for an initial base salary of $915,000, subject to annual increases, if any, agreed by us and Mr. Hockema and for an annual short-term incentive target not less than 79% of his base salary. The short-term incentive may be paid in cash, shares of the company's common stock, or a combination of cash and shares of the company's common stock, but is subject to both our meeting the applicable underlying performance thresholds and an annual cap of three times the target. If Mr. Hockema's employment terminates other than on a date which is the last day of a fiscal year, then his annual short-term incentive award with respect to the fiscal year in which his employment terminates will be determined based on the company's actual performance under the company's short-term incentive plan in which Mr. Hockema participates and prorated for the actual number of days of employment during such fiscal year, and such amount will be paid to Mr. Hockema or his estate unless his employment was terminated by us for cause. The amended and restated employment agreement provides that Mr. Hockema is entitled to receive annual equity awards (such as restricted stock units or performance shares) with a target economic value of not less than 240% of his base salary, with the portion of his annual equity awards in the form of restricted stock units equaling 36% of the target economic value, and his annual equity awards in the form of performance shares equaling 64% of the target economic value.
Under Mr. Hockema's amended and restated employment agreement, following any termination of his employment, we must pay or provide to Mr. Hockema or his estate:

• | base salary earned through the date of such termination;

• | except in the case of a termination by us for cause, earned but unpaid incentive awards;

• | accrued but unpaid vacation;

• | benefits under our employment benefit plans to the extent vested and not forfeited on the date of such termination; and

49

• | benefit continuation and conversion rights to the extent provided under our employment benefit plans.

In addition, if Mr. Hockema's employment is terminated as a result of his death or disability, at the end of the term of his employment agreement or upon his retirement during the term, all of his outstanding equity awards will vest in accordance with their terms, subject to the provisions described above, and all of his vested but unexercised grants will remain exercisable through the second anniversary of such termination. If Mr. Hockema's employment is terminated by us for cause, all of his unvested equity grants will be forfeited and all of his vested but unexercised equity grants will be forfeited on the date that is 90 days following such termination. If Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him with good reason, in addition to the payment of his accrued benefits as described above, (1) we will make a lump-sum payment to Mr. Hockema in an amount equal to 1.88 times his base salary and short-term incentive target, (2) his medical, dental, vision, life insurance and disability benefits, which we refer to as welfare benefits, will continue for two years commencing on the date of such termination, and (3) all of his outstanding equity awards will vest in accordance with their terms, subject to the provisions described above, and all of his vested but unexercised grants will remain exercisable through the second anniversary of such termination.
Notwithstanding the foregoing, if prior to July 15, 2022 a successor chief executive officer is appointed pursuant to a board-approved succession plan, the term of the amended and restated employment agreement will automatically end upon such appointment, so long as (a) the appointment occurs after July 15, 2020 and prior to a change in control (as defined in the agreement) and (b) immediately following the appointment, Mr. Hockema continues to hold the office of Chairman or is named Executive Chairman and receives annual compensation for his service in either of those capacities at least equivalent to the compensation and meeting fees payable to our lead independent director. In such event, Mr. Hockema would not be entitled to any severance payments under the amended and restated employment agreement, and his annual short-term incentive award with respect to the fiscal year in which the term of his employment agreement ends will be determined based on the company's actual performance under the company's short-term incentive plan and prorated for the actual number of days of the term during the applicable fiscal year.
If there is a change in control of our company, all of Mr. Hockema's equity awards outstanding as of the date of such change in control will vest in accordance with their terms. If Mr. Hockema's employment is terminated by us without cause or is voluntarily terminated by him with good reason within two years following a change in control, in addition to the payments of his accrued benefits as described above, (1) we will make a lump-sum payment to Mr. Hockema in an amount equal to 2.82 times his base salary and short-term incentive target, (2) his welfare benefits will continue for three years commencing on the date of such termination, and (3) all previously unvested equity grants will become exercisable and vested but unexercised grants will remain exercisable through the second anniversary of such termination. If any payments to Mr. Hockema would be subject to a federal excise tax by reason of being considered contingent on a change in control, then such payments will be reduced to the minimum extent necessary so that no portion of such payments, as so reduced, is subject to such tax, except that such a reduction will be made only if and to the extent such reduction would result in an increase in the aggregate payment on an after-tax basis.
Mr. Hockema's amended and restated employment agreement contains non-competition, non-solicitation and confidentiality restrictions following his termination of employment.
For quantitative disclosure regarding estimated payments and other benefits that would have been received by Mr. Hockema or his estate if his employment had terminated on December 31, 2019, the last business day of 2019, under various circumstances, see "— Potential Payments and Benefits upon Termination of Employment" below.
Salaried Severance Plan
Messrs. Harvey, Donnan, West and Parkinson are subject to our severance plan for salaried employees, which we refer to as our Salaried Severance Plan. Mr. Rinkenberger was subject to our Salaried Severance Plan until his retirement in March 2019. Our Salaried Severance Plan provides for payment of a termination allowance and continuation of welfare benefits upon an involuntary separation of employment that is intended to be permanent. The termination allowance and continuation of welfare benefits are not available under our Salaried Severance Plan if:

• | the employee received severance compensation or welfare benefit continuation pursuant to a Change in Control Agreement (described below) or any other agreement;

• | the employee's employment is terminated other than by us without cause; or

• | the employee declined to sign, or subsequently revokes, a designated form of release.

50

The termination allowance payable to covered employees under our Salaried Severance Plan consists of a lump-sum cash payment equal to the employee's weekly base salary multiplied by a number of weeks (not to exceed 26), which we refer to as the continuation period, determined based on the employee's number of years of full employment. Under our Salaried Severance Plan, welfare benefits are continued following the termination of employment for the shorter of the continuation period and the period commencing on the termination of employment and ending on the date that the employee is no longer eligible for coverage under the Consolidated Omnibus Budget Reconciliation Act, or COBRA. As of December 31, 2019, the continuation periods for Messrs. Harvey, Donnan, West and Parkinson were 26, 24, 10 and 26 weeks, respectively.
For quantitative disclosure regarding estimated payments and other benefits that would have been received by each of Messrs. Hockema, Harvey, Donnan, West and Parkinson or his estate if his employment had terminated on December 31, 2019, the last business day of 2019, under various circumstances, and regarding payments and benefits received by Mr. Rinkenberger upon his retirement on March 31, 2019, see "— Potential Payments and Benefits upon Termination of Employment" below.
Change in Control Agreements
In 2002, in connection with the commencement of our chapter 11 bankruptcy and the implementation of our court-approved Chapter 11 Key Employee Retention Plan, we also entered into Change in Control Agreements with certain key executives, including Messrs. Hockema, Harvey, Donnan and Rinkenberger, in order to provide them with appropriate protection in the event of a termination of employment in connection with a change in control or, except as otherwise provided, a significant restructuring. In addition, in 2008, we entered into a Change in Control Agreement with Mr. West. Mr. Hockema's employment agreement discussed above supersedes his Change in Control Agreement, and was amended to, among other things, eliminate our obligation to make excise tax gross up payments to Mr. Hockema. Mr. Rinkenberger's Change in Control Agreement terminated upon his retirement in March 2019. The Change in Control Agreements applicable to Messrs. Harvey, Donnan and West terminate on the second anniversary of a change in control.
The Change in Control Agreements provide for severance payments and continuation of welfare benefits upon termination of employment in certain circumstances. The participants are eligible for severance benefits if their employment is terminated by us without cause or by the participant with good reason during a period that commences 90 days prior to the change in control and ends on the second anniversary of the change in control. Participants also are eligible for severance benefits if their employment is terminated by us due to a significant restructuring event when there has been no change in control. These benefits are not available if:

• | the participant's employment is terminated other than by us without cause or by the participant for good reason; or

• | the participant declines to sign, or subsequently revokes, a designated form of release.

In consideration for the severance payment and continuation of benefits, a participant will be subject to non-competition, non-solicitation and confidentiality restrictions following his or her termination of employment with us.
Upon a qualifying termination of employment, each of Messrs. Harvey, Donnan and West is entitled to receive the following:

• | two times (one time for Mr. West) the sum of his base pay and most recent short-term incentive target;

• | a prorated portion of his short-term incentive target for the year of termination; and

• | a prorated portion of his long-term incentive target in effect for the year of his termination, provided that such target was achieved.

In addition, welfare benefits and perquisites are continued for a period of two years for Messrs. Harvey and Donnan and one year for Mr. West after termination of employment with us.
In general, if any payments under the legacy Change in Control Agreements with Messrs. Harvey and Donnan would be subject to federal excise tax or any similar state or local tax by reason of being considered contingent on a change in control, the participant will be entitled to receive an additional amount (a "gross-up payment") such that, after satisfaction of all tax obligations imposed on such payments, the participant retains an amount equal to the federal excise tax or similar state or local tax imposed on such payments. However, if no such federal excise tax or similar state or local tax would apply if the aggregate payments were reduced by 5%, then the aggregate payments to the participant will be reduced by the amount necessary to

avoid application of such federal excise tax or similar state or local tax. Mr. West is not entitled to any gross-up payments under his Change in Control Agreement.
The Change in Control Agreements are legacy agreements which cannot be unilaterally terminated or amended by our company without participant approval. However, we expect to continue to address the gross-up provisions in the remaining agreements when opportunities arise.
For quantitative disclosure regarding estimated payments and other benefits that would have been received by each of Messrs. Hockema, Harvey, Donnan, West and Parkinson or his estate if his employment had terminated on December 31, 2019, the last business day of 2019, under various circumstances, and regarding actual payments received by Mr. Rinkenberger upon his retirement in March 2019, see "— Potential Payments and Benefits Upon Termination of Employment" below.
2016 Plan
The 2016 Plan is an omnibus plan that facilitates the issuance of incentive awards as part of our comprehensive compensation structure and is administered by a committee of non-employee directors of our board of directors, currently the compensation committee.
Any person who is selected by the compensation committee to receive benefits under the 2016 Plan and who is at that time an officer or other key employee of Kaiser or any of our subsidiaries (including a person who has agreed to commence serving in such capacity within 90 days of the date of grant) is eligible to participate in the 2016 Plan. In addition, certain persons who provide services to us or any of our subsidiaries that are equivalent to those typically provided by an employee (provided that such persons satisfy the definition of “employee” for purposes of a Registration Statement on Form S-8 under the Securities Act of 1933, which we refer to as the "Securities Act") and non-employee directors of Kaiser may also be selected to participate in the 2016 Plan. As of December 31, 2019, there were approximately 60 employees and nine non-employee directors of Kaiser expected to participate in the 2016 Plan.
Subject to adjustment as described in the 2016 Plan, the aggregate number of shares of our common stock available for awards granted under the 2016 Plan is limited to 1,045,000 shares of our common stock, minus (1) as of the effective date of the 2016 Plan, one share for every one share subject to an award granted under the predecessor plan between December 31, 2015 and the effective date of the 2016 Plan, plus (2) any shares of our common stock that become available under the 2016 Plan as a result of forfeiture, cancellation, expiration, or cash settlement of awards. As of the date of this Proxy Statement, approximately 496,096 shares of common stock are available for additional awards under the 2016 Plan.
The 2016 Plan authorizes the issuance of option rights, appreciation rights, restricted stock, restricted stock units, cash incentive awards, performance shares, performance units and other awards, including awards in the forms of cash, shares of common stock, notes or other property.
Under the 2016 Plan, any award agreement may provide for the cancellation or forfeiture of an award or the forfeiture and repayment to Kaiser of any gain related to an award as determined by the compensation committee if a participant has engaged in any detrimental activity, either during employment by us or within a specified period after termination of employment.
Under the 2016 Plan, the compensation committee may permit non-employee directors to elect to receive shares of our common stock in lieu of any or all of the annual cash retainers paid to non-employee directors, including retainers for serving as a committee chair or Lead Independent Director.
Our board of directors generally may amend the 2016 Plan from time to time in whole or in part. However, if any amendment (1) would materially increase the benefits accruing to participants under the 2016 Plan, (2) would materially increase the number of shares or securities which may be issued under the 2016 Plan, (3) would materially modify the requirements for participation in the 2016 Plan, or (4) must otherwise be approved by our stockholders in order to comply with applicable law or the rules of the Nasdaq Stock Market, then such amendment will be subject to stockholder approval and will not be effective unless and until such approval has been obtained. Further, subject to the 2016 Plan’s prohibition on repricing, the compensation committee generally may amend the terms of any award prospectively or retroactively.
Our board of directors may, in its discretion, terminate the 2016 Plan at any time. Termination of the 2016 Plan will not affect the rights of participants or their successors under any awards outstanding and not exercised in full on the date of termination. The 2016 Plan will expire on May 26, 2026. No grants will be made under the plan after that date, but all grants made on or prior to such date will continue in effect thereafter subject to the terms thereof and of the 2016 Plan.

Savings Plan
We sponsor a tax-qualified profit-sharing and 401(k) plan, our Savings Plan, in which eligible salaried employees may participate. Pursuant to the Savings Plan, employees may elect to reduce their current annual compensation up to the lesser of 75% or the statutorily prescribed limit of $19,500 in calendar year 2020 (plus up to an additional $6,500 in the form of "catch-up" contributions for participants near retirement age), and have the amount of any reduction contributed to the Savings Plan. Our Savings Plan is intended to qualify under sections 401(a) and 401(k) of the Code, so that contributions by us or our employees to the Savings Plan and income earned on contributions are not taxable to employees until withdrawn from the Savings Plan and so that contributions will be deductible by us when made.
We match 100% of the amount an employee contributes to the Savings Plan, subject to a 4% maximum based on the employee's compensation as defined in the Savings Plan. Employees are immediately vested 100% in our matching contributions to our Savings Plan.
We also make annual fixed-rate contributions on behalf of our employees in the following amounts:

• | for our employees who were employed with us on or before January 1, 2004, we contribute in a range from 2% to 10% of the total of the employee's base salary and short-term incentive award, based upon the sum of the employee's age and years of continuous service as of January 1, 2004; and

• | for our employees who were first employed with us after January 1, 2004, we contribute 2% of the total of the employee's base salary and short-term incentive award.

As discussed more fully below, the fixed-rate contributions were implemented following the termination of our qualified, defined benefit retirement plan and resulting loss of benefit accruals under that plan. An employee is required to be employed on the last day of the year in order to receive the fixed-rate contribution. Employees are vested 100% in our fixed-rate contributions to the Savings Plan after three years of service.
The total amount of elective, matching and fixed-rate contributions in any year cannot exceed the lesser of 100% of the total of an employee's base salary and short-term incentive award or $56,000 in 2019, respectively (adjusted annually). We may amend or terminate these matching and fixed-rate contributions at any time by an appropriate amendment to our Savings Plan. Upon termination of employment, employees are eligible to receive a distribution of their vested plan balances under our Savings Plan. The independent trustee of the Savings Plan invests the assets of the Savings Plan as directed by participants.
Restoration Plan
We sponsor a nonqualified, deferred compensation plan, our Restoration Plan, in which members of our senior management and highly compensated employees may participate. Eligibility to participate in our Restoration Plan is determined by the compensation committee. The purpose of our Restoration Plan is to restore the benefit of matching and fixed-rate contributions that we would have otherwise paid to participants under our Savings Plan but for the limitations on benefit accruals and payments imposed by the Code. We maintain an account on behalf of each participant in the Restoration Plan, and contributions to a participant's Restoration Plan account to restore benefits under the Savings Plan are made generally in the manner described below:

• | if our matching contributions to a participant under the Savings Plan are limited in any year, we will make an annual contribution to that participant's account under the Restoration Plan equal to the difference between:

• | the matching contributions that we could have made to that participant's account under the Savings Plan if the Code did not impose any limitations; and

• | the maximum contribution we could in fact make to that participant's account under the Savings Plan in light of the limitations imposed by the Code; and

• | annual fixed-rate contributions to the participant's account under the Restoration Plan are made in an amount equal to between 2% and 10% of the participant's excess compensation, as defined in Section 401(a)(17) of the Code.

Participants are immediately vested 100% in our matching contributions to the Restoration Plan and are vested 100% in our fixed-rate contributions to our Restoration Plan after three years of service or upon retirement, death, disability or a change of control. Participants do not make contributions to their respective Restoration Plan accounts. A participant is entitled to
53

distributions six months following his or her termination of service, except that any participant who is terminated for cause will forfeit the entire amount of matching and fixed-rate contributions made by us to that participant's account under the Restoration Plan.
We may amend or terminate these matching and fixed-rate contributions at any time by an appropriate amendment to our Restoration Plan. The value of each participant's account under our Restoration Plan changes based upon the performance of the funds designated by the participant from a menu of various money market and investment funds.

(1) | Determined (a) assuming mortality according to the RP-2014 White Collar Healthy Annuitant mortality table, adjusted for 2006 and then projected with Scale MP-2019 and (b) applying a discount rate of 2.95% per annum.

The Old Pension Plan previously maintained by us was a qualified, defined-benefit retirement plan for our salaried employees who met certain eligibility requirements. Effective December 17, 2003, the PBGC terminated and effectively assumed responsibility for making benefit payments in respect of the Old Pension Plan. As a result of the termination, all benefit accruals under the Old Pension Plan were terminated and benefits available to certain executive officers, including Mr. Hockema, were significantly reduced due to the limitation on benefits payable by the PBGC. Benefits payable to participants will be reduced to a maximum of $34,742 annually for retirement at age 62, a lower amount for retirement prior to age 62, and
56

a higher amount for retirements after age 62, up to $43,977 annually for retirement at age 65, and participants will not accrue additional benefits. In addition, the PBGC will not make lump-sum payments to participants.

Potential Payments and Benefits Upon Termination of Employment
This section describes, and sets forth quantitative disclosure with respect to, payments and benefits to which our named executive officers, except Mr. Rinkenberger, would have been entitled if their employment had terminated on December 31, 2019, the last business day of 2019, under various circumstances. Mr. Rinkenberger retired in March 2019 and the disclosures below reflect the actual payments he received in connection with his retirement.
Voluntary Termination other than Qualified Retirement
If the employment of a named executive officer (other than Mr. Hockema, who turned 65 and qualified for retirement prior to December 31, 2019) had been voluntarily terminated by him on December 31, 2019, he would have forfeited all of his outstanding incentive awards, including his award under our 2019 STI Plan and all outstanding shares of restricted stock, restricted stock units and performance shares previously granted to him. In addition, the named executive officer would not have been eligible for severance benefits in such circumstance.
Termination for Cause
If a named executive officer’s employment had been terminated for cause on December 31, 2019, he would have forfeited all of his outstanding incentive awards, including his award under our 2019 STI Plan and all outstanding restricted stock units and performance shares previously granted to him. In addition, the named executive officer would not have been eligible for severance benefits in such circumstance.
Termination by us without Cause or by Named Executive Officer with Good Reason - No Change in Control
Under Mr. Hockema's employment agreement, if Mr. Hockema's employment had been terminated by us without cause or voluntarily terminated by him for good reason on December 31, 2019, Mr. Hockema would have been entitled to receive (1) payment of his award under our 2019 STI Plan, determined based on actual performance, (2) a lump-sum payment in an
57

amount equal to 1.88 times the sum of his 2019 base salary and 2019 STI Plan incentive target), and (3) continuation of his welfare benefits for two years commencing on December 31, 2019.

Pay Ratio
For the year ended December 31, 2019, (1) the annual total compensation of Mr. Hockema, our CEO, was $5,248,430 (the same amount as reported for him for 2019 in the Summary Compensation Table above); (2) the annual total compensation of our median employee was $74,554; and (3) the resulting ratio of the annual total compensation of our CEO to the median of the annual total compensation of all of our employees and those of our consolidated subsidiaries (other than Mr. Hockema) was 70:1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions summarized above. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K using the data and assumptions summarized below. The assumptions we used are specific to our company and our employee population. As a result, our pay ratio may not be comparable to the pay ratios of other companies. The total compensation of the median employee for the year ended December 31, 2019 was determined in the same manner as the total compensation shown for Mr. Hockema in the Summary Compensation Table.
In accordance with SEC rules, we used the same median employee identified in 2017 for purposes of calculating our pay ratio, as we determined that there have been no changes in our employee population or employee compensation arrangements since then that we reasonably believe would significantly impact our pay ratio disclosure. In 2017, we identified our median employee using the following methodology:
•we prepared a list of all employees as of December 31, 2017, which is our determination date;

• | we applied a Canadian to U.S dollar exchange rate for compensation paid in Canadian currency using the exchange rate in effect as of December 31, 2017;

• | we ranked the annual gross income of all employees for the year ended December 31, 2017, except for Mr. Hockema, using the Form W-2 compensation for our U.S. employees and Form T4 compensation for our Canadian employees; and

•we selected the employee with the median annual gross income (our "median employee").

In 2019: Mr. Hassey elected to receive 592 shares of common stock in lieu of $54,932 of his annual retainer; Ms. Martin elected to receive 377 shares of common stock in lieu of $34,982 of her annual retainer; Dr. Osborne elected to receive 835 shares of common stock in lieu of $77,480 of his annual retainer; Ms. Sebastian elected to receive 118 shares of common stock in lieu of $10,949 of her annual retainer, Mr. Stebbins elected to receive 592 shares of common stock in lieu of $54,932 of his annual retainer, and Mr. Wilcox elected to receive 336 shares of common stock in lieu of $31,177 of his annual retainer. In each case, the number of shares received was determined based on a per share price of $92.79, the average of the closing prices per share of our common stock as reported on the Nasdaq Global Select Market for the 20 trading days prior to the award date of the annual retainers.

(2) | Reflects the aggregate grant date fair value of restricted stock awards to non-employee directors determined in accordance with ASC Topic 718, without regard to potential forfeiture. On June 6, 2019, in accordance with our director compensation policy described below, each non-employee director received a grant of restricted stock having a value of $110,000; the average of the closing prices per share of our common stock as reported on the Nasdaq Global Select Market for the 20 trading days prior to the award date was $92.79, resulting in the issuance of 1,185 shares of restricted stock to each non-employee director. For additional information regarding the assumptions made in the valuation of restricted stock awards with respect to our 2019 fiscal year, see Note 6 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. As of December 31, 2019, each non-employee director, except Mr. Gerard, held 1,185 shares of restricted stock. Mr. Gerard held 896 shares of restricted stock as of December 31, 2019. The restrictions on 100% of the shares of restricted stock granted to non-employee directors will lapse on June 6, 2020 or earlier if the director's services to our company terminate as a result of death or disability, or in the event of a change in control. The non-employee director will receive all dividends and other distributions paid with respect to the shares of restricted stock he or she holds, but if any of such dividends or distributions are paid in shares of our capital stock, such shares will be subject to the same restrictions on transferability as are the shares of restricted stock with respect to which they were paid.

Director Compensation Arrangements
We periodically review director compensation in relation to other comparable companies and in light of other factors that the compensation committee deems appropriate and discuss director compensation with the full board of directors. During 2019, the market pay analysis performed by Meridian reflected that (i) our non-employee director's total compensation was approximately 5% below the median of the peer group, (ii) our non-employee director's cash retainer was approximately 25% below the median, (iii) our non-employee director's equity retainer was slightly below the median, and (iv) the committee chair retainers were also below the median.
Pursuant to our director compensation policy, each of our non-employee directors receives the following compensation:

• | an annual retainer of $55,000 per year;

• | an annual grant of restricted stock having a grant date value equal to $110,000;

• | a fee of $1,500 per day for each meeting of our board of directors attended in person and $750 per day for each such meeting attended by phone; and

• | a fee of $1,500 per meeting for each in-person board committee meeting attended ($2,000 per meeting for each such audit committee meeting) and $750 per meeting for each telephonic board committee meeting attended ($1,000 per meeting for each such audit committee meeting).

In addition, pursuant to our director compensation policy, our Lead Independent Director receives an additional annual retainer of $15,000, the chair of the audit committee receives an additional annual retainer of $15,000, the chair of the compensation committee receives an additional annual retainer of $10,000, the chair of the nominating and corporate governance committee receives an additional annual retainer of $7,500 and the chair of the talent development committee receives an additional annual retainer of $7,500, with all such amounts payable at the same time as the annual retainer. Each non-employee director may elect to receive shares of common stock in lieu of any or all of his or her annual retainer, including any additional annual retainer for service as the Lead Independent Director or the chair of a committee of the board of directors. Our stock ownership guidelines require our non-employee directors to own company stock equal in value to six times their annual base retainer.
The payment of annual retainers, including any additional annual retainer for service as Lead Independent Director or the chair of a committee of our board of directors, and the annual grant of restricted stock is made each year on the date on which we hold our annual meeting of stockholders, unless our board of directors determines such payment and grant should occur on another date. The number of shares of common stock to be received in the grant of restricted stock, as well as the number of shares of common stock to be received by any non-employee director electing to receive our common stock in lieu of any or all of his or her annual retainer, including any additional annual retainer, is based on the average of the closing prices per share of our common stock for the 20 trading days prior to the date such grant and payments are made.
We reimburse all of our directors for reasonable and customary travel and other disbursements relating to meetings of our board of directors and committees thereof, and non-employee directors are provided accident insurance with respect to company-related business travel.

The performance awards assume maximum payout, and, as a result, this aggregated reported number may overstate actual dilution.

(3) | Subject to certain adjustments that may be required from time to time to prevent dilution or enlargement of the rights of participants, a maximum of 1,045,000 shares of our common stock, less any common shares subject to awards granted under the 2006 Plan between December 31, 2015 and May 26, 2016, plus any common shares that become available under the 2016 Plan as a result of forfeiture, cancellation, expiration or cash settlement of awards under the 2006 Plan after December 31, 2015, may be issued under the 2016 Plan. All of these shares may be issued with respect to award vehicles other than just stock options or stock appreciation rights or other rights to acquire shares.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
Our corporate governance guidelines require that our board of directors conduct an appropriate review of all related-party transactions. The charter for the audit committee of our board of directors requires that any related-party transaction required to be disclosed under Item 404 of Regulation S-K must be approved by the audit committee. Neither our board of directors nor the audit committee has adopted specific policies or procedures for review or approval of related-party transactions.
AUDIT COMMITTEE REPORT
The audit committee charter requires the audit committee to undertake a variety of activities designed to assist our board of directors in fulfilling its oversight role regarding our independent registered public accounting firm's independence, our financial reporting process, our internal control over financial reporting and our compliance with applicable laws, rules and regulations. These requirements are briefly summarized under "Corporate Governance - Board Committees - Audit Committee" above. The audit committee charter also provides that the independent registered public accounting firm is ultimately accountable to our board of directors and the audit committee, not our management.
Our internal accountants prepare our consolidated financial statements and our independent registered public accounting firm is responsible for auditing those financial statements. The audit committee oversees the financial reporting processes implemented by our management but does not conduct any auditing or accounting reviews. The members of the audit committee are not company employees. Instead, the audit committee relies, without independent verification, on our management's representation that the financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and on the report of our independent registered public accounting firm on our financial statements. The audit committee's oversight does not provide it with an independent basis for determining whether our management has maintained appropriate accounting and financial reporting principles or policies or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the audit committee's discussions with our management and its accountants do not ensure that the financial statements are presented in accordance with accounting principles generally accepted in the United States of America or that the audit of our financial statements has been carried out in accordance with auditing standards of the Public Company Accounting Oversight Board or that our independent registered public accounting firm is in fact "independent."
We have engaged Deloitte & Touche LLP as our independent registered public accounting firm to audit and report to our stockholders on our financial statements for 2020 and the effectiveness of our internal control over financial reporting as of December 31, 2020. The audit committee reviews annually the independence and performance of Deloitte & Touche LLP in connection with the audit committee's determination of whether to retain Deloitte & Touche LLP or engage another firm as our independent registered public accounting firm. In the course of these reviews, the audit committee considers, among other things:
•the historical and recent performance of Deloitte & Touche LLP on our company's integrated audit;
•an analysis of known risks and significant proceedings involving Deloitte & Touche LLP, if any;

• | external data relating to the audit quality and performance, including recent Public Company Accounting Oversight Board reports on Deloitte & Touche LLP and its member firms;

67

• | the appropriateness of Deloitte & Touche LLP's fee;

• | Deloitte & Touche LLP's tenure as our independent registered public accounting firm and its familiarity with our operations and businesses, accounting policies and practices and internal control over financial reporting;

• | Deloitte & Touche LLP's capability and expertise in relation to the breadth and complexity of our operations; and

• | Deloitte & Touche LLP's independence.

Based on its review the audit committee believes that Deloitte & Touche LLP is independent and that it is in the best interest of our company and our stockholders to retain Deloitte & Touche LLP to serve as our independent registered public accounting firm for 2020.
In accordance with rules of the Securities and Exchange Commission and Deloitte & Touche LLP's policies, audit partners are subject to rotation requirements to limit the number of consecutive years an individual partner may provide service to our company. For lead audit and engagement quality control review partners, the maximum number of consecutive years of service in that capacity is five years. The process for approval of the lead audit partner for our company pursuant to this rotation policy involves a meeting between the chair of the audit committee and the candidate for the role, as well as discussion by the full committee and with management.
The audit committee has discussed with management and Deloitte & Touche LLP significant accounting policies applied by us in our financial statements as well as alternative treatments and significant judgments and estimates, including (1) revenue recognition and (2) the recoverability of the goodwill of Imperial Machine & Tool Co. For a more detailed discussion of these accounting items, see Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2019. During the year ended December 31, 2019, there were no disagreements with Deloitte & Touche LLP on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure, which, if not resolved to the satisfaction of Deloitte & Touche LLP, would have caused them to make a reference to the subject matter of the disagreement in connection with its reports.
The audit committee reviewed and discussed the company's audited financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2019 with our management. The audit committee has also discussed with our independent registered public accounting firm the matters required to be discussed pursuant to the applicable requirements of the Public Company Accounting Oversight Board and the SEC.
The audit committee also received and reviewed the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the audit committee concerning independence, and has discussed with Deloitte & Touche LLP its independence.
The audit committee discussed with our internal accountants and Deloitte & Touche LLP the overall scope and plans for their respective audits. The audit committee meets with management, our internal accountants and our independent accountants periodically in separate private sessions to discuss any matter that the audit committee, our management, our internal accountants, the independent accountants or such other persons believe should be discussed privately.
Based on the review and discussions referred to above, the audit committee recommended to our board of directors that our audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2019, as filed with the Securities and Exchange Commission.
The audit committee considered whether, and concluded that, the provision by Deloitte & Touche LLP of the services for which we paid the amounts set forth under "Independent Public Accountants - Tax Fees" and "Independent Public Accountants - All Other Fees" below is compatible with maintaining the independence of Deloitte & Touche LLP.
