CEO Letter

Dear Shareholders,

I am pleased to report that West continues to build on our important role in the healthcare industry. Our market-led strategy to offer integrated containment and delivery solutions for injectable therapies, tailored to the unique needs of our customers, while offering the best technical and scientific support that these products and services require, has once again translated into a year of sustained growth and profitability, as well as healthy shareholder returns.

West manufactures more than 41 billion components each year, across 27 manufacturing sites. Two years ago, we began a process to globalize our operations to ensure we maximize our returns on invested capital and take full advantage of this global footprint to drive improved profitability and better service to customers. Through lean manufacturing, a streamlined supply chain and improved vendor management, we are already seeing significant improvements from these efforts, with more to come. This is all-the-more impressive when you consider our team has achieved these results while maintaining best-in-class quality levels and improving our recordable injury rate across the Company—boasting the lowest injury levels in West's history.

We are grateful to our Board of Directors for their support and guidance. Under the leadership of our chairman, Patrick Zenner, they have partnered with our Management team as we continue to refine our strategy, and they have challenged us along the way to ensure we are addressing internal and external risks while managing towards our long-term success. We are fortunate to have a Board rich with diverse experience across a number of industries, with deep insight into the delivery of healthcare.

In 2018, we were proud to be recognized for our commitment to the communities in which we live and work. As will be further detailed in our 2018 Corporate Responsibility Report, to be published later this year, we have made significant improvements in our environmental sustainability efforts, which were recognized by the CPHI with their 2018 Excellence in Pharma: Corporate Social Responsibility Award. Our efforts to support the community through our philanthropic activities also received recognition with the CEO Connection's Mid-Market Social Impact Award.

The team at West is committed to achieving our vision to serve as the world leader in the integrated containment and delivery of injectable medicines. We have worked to ensure the performance of our team is reflected in their compensation and awards framework and is aligned with the results we have delivered. The detailed pay-for-performance plans of our executives, which have received more than 96 percent support from you, our shareholders, are detailed in this Proxy Statement for your review.

With the support of our Board, and the continued investment of our shareholders, we feel we are well-positioned to fulfill our vision, and our everyday commitment to the customers and patients we work to serve.

Thank you for your continued support of West.

Regards,

Eric M. Green
President and CEO

2018 Business Highlights

Our market-led strategy focusing on the containment and delivery of injectable medicines and success in globalizing our operations is evident in our 2018 performance and is driving our outlook for 2019 and beyond. The trends in the pharmaceutical and biotech industry also support our long-term growth strategy:

•

More prescription medications are being developed as injectable drugs

•

Our customer base continues to grow around the world, with faster growth in Asia Pacific and South America

•

The bar for quality and reliability continues to be raised by both our customers and global regulators

•

Our customers continue to request technical and regulatory services to support the packaging and delivery of their products

•

Pharmaceutical companies are looking to couple their drugs with differentiated delivery devices to improve patient adoption and adherence

Each year, we have seen growing interest and demand for our high-value product offerings, delivery device platforms and our contract-manufacturing services. This demand has translated into positive results for the business. In 2018, we reported:

•

Full-year 2018 reported net sales of $1.717 billion, which reflects 7.4% growth over the prior year. At constant foreign currency exchange rates, organic sales growth was 5.6%.

•

Full-year 2018 reported-diluted Earnings-Per-Share ("EPS") was $2.74, compared to $1.99 last year. Full-year 2018 adjusted-diluted EPS was $2.81, compared to $2.78 in the prior year.

•

Full-year 2018 gross profit margin was 31.8%, a 30-basis point decline from the prior year. While the Proprietary Products segment gross profit margin expanded by 80 basis points, Contract-Manufactured Products segment gross profit margin declined by 280 basis points due to unabsorbed overhead from plant consolidation activities, start-up costs associated with the launch of new programs and unfavorable sales mix.

2019 Annual Meeting and Proxy Statement   |   1

PROXY SUMMARY

•

Full-year 2018 operating cash flow ("OCF") was $288.6 million, representing a 9.6% increase over 2017 OCF of $263.3 million.

•

Capital expenditures in 2018 were $104.7 million, a 20% reduction compared to 2017 capital expenditures of $130.8 million.

As we look to 2019, we expect to grow sales and expand profit margins in line with our long-term financial construct, with full-year 2019 constant-currency organic sales growth in a range between 6% and 8% and full-year 2019 operating profit margin expansion of approximately 100 basis points. Please refer to our Earnings Release filed on February 14, 2019 on Form 8-K for a full reconciliation of our reported results to the adjusted (non-GAAP) financial measures referred to above.

Long-Term Shareholder Return

If we examine our results over the past five years, West has consistently delivered against its objectives, posting long-term sales growth and steady EPS improvements. The Company has also outperformed both our peers and the market overall in Total Shareholder Return ("TSR") during this same period.

Please refer to Note 3: Revenue in our 2018 Form 10-K, which addresses new accounting guidance on revenue recognition.

Please refer to our Forms 8-K dated February 14, 2019 and January 9, 2019 for a reconciliation of non-GAAP financial matters.

Looking to the future, we expect West's organic sales growth and margin expansion to be further supported by strong underlying market drivers. West's reputation as a scientific and technical leader in the industry, combined with the breadth and depth of our product and service portfolio as well as our unsurpassed global footprint, allows us to serve as a global partner to customers across the injectable drug and medical device landscape. Our officers, employees and directors are focused on maintaining and growing the important role we play as a leader in the healthcare industry.

PROXY SUMMARY

Our Director Nominees

You are being asked to vote on the directors nominated below. John Weiland, who retired as President and Chief Operating Officer of C. R. Bard, Inc. following its acquisition by Becton, Dickinson and Company in 2017, and who has been a director since 2007 has decided to retire from our Board after 12 years of outstanding service. Mr. Weiland's leadership, first as Chairman of the Compensation Committee, and later as Chairman of the Finance Committee, has been instrumental to our success. Because Mr. Weiland is not standing for reelection, our Board will also be reduced from 11 to 10 members as of his retirement. All directors are elected annually by a majority of votes cast, except in the case of a contested election where the number of nominees exceeds the number of open positions, in which case plurality voting is used. The charts below summarize some key characteristics of the members of our Board of Directors. All data is as of March 22, 2019. Detailed information about each director's background and areas of expertise can be found beginning on page 9.

PROXY SUMMARY

2018 Executive Compensation Highlights

Executive Compensation Program Features

Strong linkage between pay and performance and support by shareholders regarding our performance metrics, targets and goals as evidenced by more than 96% shareholder approval annually of our executive compensation

Total direct compensation ("TDC"), which is the sum of an officer's base salary, short-term incentive target and long-term incentive target, targeted at the median level by our Compensation Committee

Annual incentive plan ("AIP") based on EPS, revenue and OCF targets to drive shareholder value in day-to-day decision making

Long-term incentive ("LTI") plan utilizing stock options and performance share units based upon return on invested capital ("ROIC") and consolidated annual growth rate ("CAGR") to ensure long-term profitable growth and alignment with shareholders' interests

Usage of two comparator groups to ensure pay and performance are aligned, and enable us to attract and retain the best talent

Robust share ownership guidelines for all officers and directors

All Change-in-Control ("CIC") agreements for our current officers contain double-trigger provisions requiring termination of the executive following a CIC before payments are made. These payments also may be cutback if they exceed excise tax thresholds under applicable tax law.

Strong incentive compensation recovery (clawback) and anti-hedging and anti-pledging policies

Use of tally sheets, realizable pay analysis, performance metric difficulty analysis and similar tools to ensure our compensation programs remain linked to performance and consistent with Board expectations

Engagement with shareholders during the year regarding executive pay and performance issues

Executive Compensation Actions and Results

Further refined the Company's AIP to simplify compensation, drive stronger alignment with, and better line of sight to, our business objectives

To further align with our employee population, we moved the effective date of officer salary increases from May to March and eliminated incentive share matching in our bonus program for AIP amounts earned after 2019

Strengthened and modernized our employee stock ownership requirements

Conducted market review of our independent Compensation Committee executive compensation consultant, and renewed with Pay Governance for a three-year period ending in 2021

Conducted formal: (1) pay-for-performance review of CEO compensation versus peers, and (2) realizable pay analysis, to assess whether Company performance and CEO realizable pay are aligned over a given period

ELECTION OF DIRECTORS

Election of Directors

Director Nominations, Skills and Criteria

Candidates for nomination to our Board are recommended by the Nominating and Corporate Governance Committee ("NCGC") in accordance with the Committee's charter, our Articles of Incorporation, our Bylaws and our Corporate Governance Principles. All persons recommended for nomination to our Board, regardless of the source of the recommendation, are evaluated by this Committee with the Board determining the final slate of nominees.

The Board and the NCGC consider, at a minimum, the following factors in recommending potential new Board members or the continued service of existing members:

•

A director is nominated based on his or her professional experience. A director's traits, expertise and experience add to the skill-set of the Board as a whole and provide value in areas needed for the Board to operate effectively.

•

A director must have high standards of integrity and commitment, and exhibit independence of judgment, a willingness to ask hard questions of Management and the ability to work well with others.

•

A director should be willing and able to devote sufficient time to the affairs of the Company and be free of any disabling conflict.

•

All the non-employee directors should be "independent" as outlined in our independence determination standards ("Independence Standards").

•

A director should exhibit confidence and a willingness to express ideas and engage in constructive discussion with other Board members, Management and relevant persons.

•

A director should actively participate in the decision-making process, be willing to make difficult decisions, and demonstrate diligence and faithfulness in attending Board and Committee meetings.

•

The Board generally seeks active or former senior executives of public companies, particularly those with international operations, leaders in healthcare or public health fields, with science or technology backgrounds, and individuals with financial expertise.

When reviewing nominees, the NCGC considers whether the candidate possesses the qualifications, experience and skills it considers appropriate in the context of the Board's overall composition and needs. The NCGC also values diversity on the Board in the director nominee identification and nomination process.

To assist it with its evaluation of the director nominees for election at the 2019 Annual Meeting, the NCGC considered the factors listed above and used a skills matrix highlighting the experience of our directors in areas such as industry experience, international experience (including assignments overseas), global operations or supply chain leadership, financial literacy, and independence. In the past two years, we have also added skills such as, marketing (including e-commerce), mergers and acquisitions, regulatory and cyber/digital experience, to our skills matrix.

The NCGC also reviews annually with the Board the size and composition of the Board and its committees to determine the qualifications and areas of expertise needed to further enhance the composition of the Board. In determining whether to add new directors, we review our skills matrix annually to determine the targeted skills that we believe will most significantly enhance the diversity of experience and expertise on our Board. We balance the current skill sets versus the desired optimal mix of skill sets given their relative importance to the Company.

Board members are expected to support Management to drive success in our current strategic plans, which includes:

•

Transforming the business to a market-led organization with enhanced commercial effectiveness

•

Expanding into emerging markets

•

Optimizing operations and supply chain networks

•

Leveraging global innovation and technology to accelerate product development

•

Accelerating digitization to drive performance

•

Building global leadership bench depth, diversity and inclusion

6   |   2019 Annual Meeting and Proxy Statement

ELECTION OF DIRECTORS

Under the heading "Director Nominee Biographies," we provide an overview of each nominee's principal occupation, business experience and other directorships of publicly-traded companies, together with the qualifications, experience, key attributes and skills the Committee and the Board believe will best serve the interests of the Board, the Company and our shareholders.

Shareholders who wish to recommend or nominate director candidates must provide information about themselves and their candidates and comply with procedures and timelines contained in our Bylaws. These procedures are described under "2020 Shareholder Proposals or Nominations" in this Proxy Statement.

Board Commitment to Diversity and Inclusion

Board diversity and inclusion is critical to the success of West. The Board is committed to ensuring its membership has sufficient diversity of experience, skills and personal characteristics to support the long-term success of the Company. As presently constituted, the Board represents a deliberate mix of members who have a deep understanding of our business as well as members who have different skill sets and points of view. As noted above, our nomination process and our Board's approach to assessment and evaluation of our nominees support this diversity and inclusion commitment.

Our Corporate Governance Principles include a statement regarding the importance of Board diversity and inclusion to ensure that the director nomination process considers a diverse mix of background, age, gender, sexual orientation, as well as cultural and ethnic composition. Additionally, the NCGC's evaluation of director nominees includes consideration of their ability to contribute to the diversity of personal and professional experiences, opinions, perspectives and backgrounds on the Board.

While we are pleased with the current complement of diverse backgrounds of our directors, we continually assess the size and diversity of the Board. We review our Board skills matrix annually and develop a list of skills and characteristics that we feel would supplement our current diverse mix of experiences and backgrounds the identified skills include: financial expertise, industry, direct international oversight, mergers and acquisitions, cyber or digital experience and a diverse gender, ethnic or racial background.

We are particularly proud of our leadership in female representation on the Board. One-third of our independent directors standing for reelection (30% of all directors) are women. Several of our Board members participate in diversity in leadership programs and others are high-profile speakers on issues of diversity and inclusion.

Our Board has overseen efforts by the Company to increase diversity and inclusion among its employee base. Mr. Green's annual objectives include diversity and inclusion as a key metric, and we have also added new positions responsible for diversity. The Board believes this approach enables us to attract and retain diverse high-quality talent. This has culminated in a diversity mission statement, which can be found in our CR Report at www.westpharma.com/about-west/corporate-responsibility. As part of our diversity mission, we have trained employees at all levels on the importance of diversity and inclusion, introduced affinity groups, accelerated efforts in minority recruiting and modified our culture to increase flexibility and mentoring, which we believe facilitates diversity and inclusion.

Board Refreshment and Retirement Age

We review our Board refreshment policies and retirement age annually and continue to monitor broad governance trends in this area. The Board has considered but does not have term limits on the service of our directors, because we believe that term limits may lead to the loss of valuable director insight into our business and operations that is enhanced with continuity.

The Board believes that a diverse mix of long-tenured and new Board members provides a good and appropriate balance of experience to enhance shareholder value. The Board believes that directors provide meaningful, independent oversight and advice at any age. Our Corporate Governance Principles include a mandatory retirement age of 75. This means that a non-employee director must retire on the date of the Annual Meeting of Shareholders immediately following his or her 75th birthday.

An employee director must submit his or her resignation upon the date he or she ceases to be an executive officer of the Company.

2019 Annual Meeting and Proxy Statement   |   7

ELECTION OF DIRECTORS

Board Evaluation Process

Each year the Board and each of its committees review their performance during executive sessions. This review centers around questions directors are asked to contemplate regarding their individual performance and the performance of the Board/Committee. These questions include topics such as the relationship between members, quality of the materials provided, the relationship with Management, contributions to key functions/responsibilities of the Board, and topics that they would like to see added or deleted to meeting agendas.

Additionally, the NCGC assesses the evaluation process annually and makes suggested changes when necessary. The NCGC reviews several matters, including the issues to focus on in the evaluation and the form and manner of assessment. The NCGC periodically re-assesses its position on self-evaluation.

During the past two years, the chair of the NCGC reached out to each director individually to discuss any concerns and relayed them to the Board using an interview template approved by the NCGC. In 2018, we revised this process to include all members of the NCGC reaching out to members of the full Board to obtain different perspectives, to encourage collecting as much candid information as possible and to ensure the proper level of engagement.

We believe this evaluation system, coupled with our strong Chairman of the Board and open-door policy, which encourages sharing of ideas among all directors, makes for a robust process that ensures the Board's effectiveness.

DIRECTOR NOMINEE BIOGRAPHIES

Proposal 1 — Election of Directors

Our shareholders are asked to consider ten nominees for election to our Board to serve for a one-year term until the 2020 Annual Meeting of Shareholders, and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. As noted above, Mr. Weiland has decided to retire and not stand for reelection, and, therefore, our Board will be reduced from 11 to 10 members. The names of the nominees for director, their current positions and offices, tenure as a Company director, their qualifications and other characteristics are set forth in the biographies below. The table below also lists each nominee's current Board committees, which changed effective February 19, 2019. Their previous committee assignments, including all of 2018 through February 19, 2019, can be found in our 2018 Proxy Statement.

All the nominees are current Company directors and all non-employee directors have been determined by our Board to be independent. Our NCGC reviewed the qualifications of each of the nominees, finding each nominee to possess the required attributes and possesses the appropriate balance of diversity of knowledge, age, skills, expertise, gender and race, and recommended to our Board that each nominee be submitted to a vote of our shareholders at the Annual Meeting. The Board approved the Committee's recommendation at its meeting on February 19, 2019.

Each of the nominees has agreed to be named and to serve, and we expect each nominee to be able to serve if elected. If any nominee is unable to serve, the NCGC will recommend to our Board a replacement nominee. The Board may then designate the replacement nominee to stand for election. If you voted for the unavailable nominee, your vote will be cast for his or her replacement.

BOARD AND DIRECTOR INFORMATION AND POLICIES

Board and Director Information and Policies

Our Board structure reflects our Corporate Governance Principles and commitment to good governance. We believe the governance structure we have created between the Board, its Committees, the Board Chair, the CEO and Management, is supporting the sustainable growth of the Company.

During 2018, our Board met five times. All of our Board members attended all Board meetings and more than 94% of the combined total of all Board and Committee meetings in 2018. Our Board is committed to ensuring that directors attend meetings and that the Board and its Committees devote sufficient time necessary for the effective oversight of the Company and its Management. Additionally, annually during the review process, the Board assesses the time commitments for our Board against the time commitments of a member's outside positions to ensure there is sufficient time to devote to their duties as a West director.

Our Board also holds regular executive sessions of only independent directors to review, among other things, the Company's strategy and Management's operating plans, the criteria by which our CEO and other senior executives are measured, Management's performance against those criteria and other related issues and to conduct a self-assessment of its performance. Last year, our independent directors held five executive sessions.

All of our directors attended the 2018 Annual Meeting and all directors that are standing for reelection are expected to attend the 2019 Annual Meeting.

Board Leadership Structure

The current governance structure of the Board follows:

•

The offices of Chairman and CEO are separate

•

The Board has established and follows robust Corporate Governance Principles

•

All the members of the Board, other than Mr. Green, are independent

•

All Board Committees are composed solely of independent directors

•

Our independent directors meet regularly in executive session both at the Board and Board committee levels

•

Our directors as a group possess a broad range of skills and experience sufficient to provide the leadership and strategic direction the Company requires as it seeks to enhance long-term value for shareholders

While the offices of Chairman and CEO are currently separate, the Board takes a flexible approach to the issue of whether the offices of Chairman and CEO should be separate or combined. This approach allows the Board to regularly evaluate whether it is in the best interests of the Company for the CEO or another director to hold the position of Chairman.

The Board does not currently have a lead independent director, although the Board believes it may be useful and appropriate to designate a lead independent director if the offices of Chairman and CEO are combined in the future.

We believe the current Board leadership structure is appropriate now because it allows the Chairman to focus on corporate governance and management of the Board's priorities and allows the CEO to focus directly on managing our operations and growing the Company.

Chairman of the Board of Directors

The responsibilities of the Chairman include:

•

Chairing Board meetings, including executive sessions of the independent directors

•

Approving agendas and schedules for each Board meeting in consultation with the CEO

•

Serving as principal liaison between the CEO and the independent directors

Each independent director may add items to the agenda.

2019 Annual Meeting and Proxy Statement   |   15

BOARD AND DIRECTOR INFORMATION AND POLICIES

Our current Chairman, Mr. Zenner, has been serving on the Board since 2002, and as our Chairman since 2015. Each year the Board considers the role of the Chairman and who is sitting in that role. We believe Mr. Zenner's experience as a top executive plus independence and history with the Company makes him a valuable asset for the Company, and he provides significant leadership and perspective to our Board.

Committees

The Board has five standing committees:

•

Audit Committee

•

Compensation Committee

•

Finance Committee

•

•

Each standing committee has a written charter, which is posted in the "Investors—Corporate Governance" section of our website at www.westpharma.com.

BOARD AND DIRECTOR INFORMATION AND POLICIES

The Board's Role in Risk Oversight

The Board and its Committees play an active role in overseeing Management's day-to-day responsibility for assessing and managing our risk exposure.

The Board regularly reviews and monitors the risks associated with our enterprise strategy, financial condition and operations and specifically reviews the enterprise risks associated with our five-year plan. In particular, the Board reviews our risk portfolio, confirms that Management has established risk-management processes that are functioning effectively and efficiently and are consistent with our corporate strategy, reviews the most significant risks and determines whether Management is responding appropriately.

The Board performs its risk oversight role by using several different levels of review. Each Board meeting begins with a strategic overview by the CEO that describes the most significant issues, including risks, affecting the Company as well as business updates from each reportable segment. In addition, the Board reviews in detail the business and operations of each reportable business segment quarterly, including the primary risks associated with that segment.

Our Enterprise Risk Management ("ERM") program helps us manage the risks inherent in our business, by gaining a greater understanding and awareness of risks facing the business, ensure risk-appropriate mitigation efforts are in place and regularly monitors and ensures the Company meets or exceeds the expectation of all stakeholders, including investors and regulators.

The ERM program includes a Risk Identification and Management ("RIM") process, crisis management, business continuity and disaster recovery elements, set forth in additional detail in the chart below:

The Board focuses on the overall risks affecting the Company. Each Board Committee has been delegated the responsibility for the oversight of specific risks that fall within its areas of responsibility, as cataloged through the RIM process, including:

•

The Audit Committee oversees management of financial reporting, compliance, litigation and cybersecurity risks as well as the steps Management has taken to monitor and control such exposures. This Committee also oversees the processes used in our ERM program

•

The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation policies, plans and arrangements and the extent to which those policies or practices increase or decrease risk for the Company

•

The Finance Committee assesses the risks associated with allocation of our capital, potential acquisitions, divestitures and major business partnerships

•

The Innovation and Technology Committee reviews risks associated with intellectual property, innovation efforts and our technology strategy

•

The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board, potential conflicts of interest and the effectiveness of the Board

Although each Committee is responsible for evaluating certain risks and overseeing the management of those risks, the full Board is regularly informed about those risks through regular Committee reports.

Cybersecurity.    The full Board and the Audit Committee both participate in the vital work necessary to understand our cybersecurity risk and oversee the related risk mitigation activities. This has become more critical as we launched a new e-commerce website during 2018 and due to the expansion of privacy regulations in Europe. The Audit Committee reviews cybersecurity risk at every live meeting, holds private sessions with our Chief Digital and Transformation Officer and reviews our

18   |   2019 Annual Meeting and Proxy Statement

BOARD AND DIRECTOR INFORMATION AND POLICIES

Cybersecurity dashboard at all in-person meetings. Additionally, our Senior Director, Infrastructure and Cybersecurity, Senior Director, Internal Audit, and Chief Compliance Officer separately meet with the Committee to provide additional insight into our cybersecurity and privacy strategy and tactics.

Our approach to mitigating cybersecurity risks includes review by third party experts, training for directors (both internally and externally), holding within the Company a global cybersecurity awareness week, and the adoption of the National Institute of Standards and Technology Framework for Improving Critical Infrastructure Cybersecurity (the "NIST Framework"). The NIST Framework provides a comprehensive framework to develop a flexible, repeatable, performance-based and cost-effective approach to identifying and managing cybersecurity risks. We measure ourselves against this framework to assess our own maturity on cybersecurity.

Our cybersecurity defenses utilize technologies such as firewalls, intrusion detection, and encryption to ensure the privacy and security of our customers' data, with a dedicated security information and event management team monitoring our applications constantly.

Executive Officer Succession Planning

One of the primary responsibilities of the Board is to ensure that West has the appropriate management to execute our long-term strategy. Our Corporate Governance Principles state the Board must plan for succession with respect to the CEO and monitor Management's succession planning for other key executives. In fulfilling this duty, the Board, together with the CEO and Chief Human Resources Officer ("CHRO") reviews at least annually, the development and retention plans of senior management talent as well as succession plans for the CEO and other senior management positions.

During these reviews, the Board discusses:

•

Management performance

•

Strengths and developmental opportunities needed to prepare senior leaders for greater responsibilities

•

Potential internal development job changes

•

Succession plans including leadership pipeline, development plans and timelines

•

Diversity of leadership and pipeline candidates

•

Detailed assessment of the members of the executive leadership team who potentially could succeed the CEO. This review includes a discussion about development plans to help prepare each individual for future succession.

In addition, our CEO has as an annual goal for the development of senior leaders and the creation of a global succession plan for key positions within the Company. Therefore, he prepares detailed succession plans and contingency plans in the event that he is unable to serve as CEO for any reason including death or disability. These plans are reviewed annually by the NCGC and discussed with the Board. Finally, throughout the year, Board members are exposed to leadership and pipeline candidates through Management presentations, roundtable discussions, and other informal meetings to assess the depth of our leadership pipeline.

CEO Evaluation Process

In assessing the performance of our CEO, the independent directors engage in a robust assessment process that is managed throughout the year and culminates in a formal annual performance review. The assessment includes the following:

•

Independent directors approve the CEO annual business objectives consisting of both qualitative and quantitative progress against Customer Experience, Operational Effectiveness, Products & Services Expansion, Enterprise Capabilities, People and Culture and Financial Goals

•

A comprehensive analysis is undertaken by our Compensation Committee's independent consultant on the robustness of West's financial targets and compare these against our Business Segment Group's performance

•

Each quarter, the independent directors review the progress made against each objective

•

The CEO undertakes a self-assessment of performance against the approved annual objectives

•

Annual anonymous evaluation of the CEO's individual performance by the independent directors on numerous factors, including: leadership, strategic planning, financial performance, employee development and engagement, external and internal relations and interactions with the Board

2019 Annual Meeting and Proxy Statement   |   19

BOARD AND DIRECTOR INFORMATION AND POLICIES

•

An analysis of West's total performance over a multi-year period, a competitive benchmark analysis, and other relevant information is submitted to the independent directors

Working with the Compensation Committee's independent compensation consultant, the Chair of the Compensation Committee considers all of this information in developing its recommendations for compensation, as discussed below in our "Compensation Discussion and Analysis."

Corporate Responsibility

As a leader in our industry, we recognize our responsibility to conduct business in a sustainable manner and strive to be a good corporate citizen. Our CR efforts include six key areas of focus: Compliance and Ethics, Philanthropy, Diversity and Inclusion, Health and Safety, Environmental Sustainability and Quality. During 2018, we engaged our shareholders on this important topic, as well as more than 30 key customers. Detailed below is a brief overview of our progress. We will report more fully on our CR accomplishments in our 2018 CR report, which is expected to be published in June.

Compliance & Ethics.    Our Compliance and Ethics standards include holding ourselves to the highest standards of quality, integrity and respect as outlined in our Code of Business Conduct ("COBC"), which is supported by our training program led by our Chief Compliance Officer, and our annual Compliance Week efforts.

Philanthropy.    West has long-placed importance in supporting charities, particularly as it relates to children, people with disabilities, healthcare and Science Technology Engineering and Math ("STEM") education in the communities where we live and work. In 2018, charitable giving by the Company, our employees and the Herman O. West Foundation totaled approximately $2.5 million. Our philanthropic efforts, and particularly our President and CEO's leadership in this area, were recognized by CEO Connection, a global organization focused on supporting mid-market CEOs and their shareholders, with their 2018 Social Impact Award.

Diversity and Inclusion.    As discussed above, we strive to create and maintain a workplace rich with diverse people, talent and ideas, and to create an inclusive environment for all employees to succeed. We have increased awareness, adopted affirmative action programs, and strengthened programs and policies, which includes the adoption of our first global anti-discrimination and anti-harassment policy in 2018.

Health and Safety.    A healthy and safe environment is a fundamental right for all people. We have developed new safety protocols and procedures to create a culture of safety, which incorporates behavior-based training and observations. We consistently aim to have a zero-injury workplace and monitor our progress to that goal, which has resulted in a reduction of injuries over the past three years by more than 60%. These goals are set using globally-recognized benchmarks included in our CEO's annual performance objectives.

Environmental Sustainability.    We strive to be stewards of a sustainable future by factoring environmental considerations into our decision making for raw materials, production processes and distribution methods. Our emissions, energy and water intensity goals established in 2013 for 2020 have already been exceeded and will be reset in 2019. West has also continuously improved our rating under the Carbon Disclosure Project about 5% annually since 2013, culminating in our highest rating ever in 2018. We have also received multiple awards for our Corporate Responsibility efforts, which are set forth in more detail on our website at www.westpharma.com/about-west/corporate-responsibility. The information on that website is updated periodically, and believed to be true at the time it is posted, but it is not filed with and does not constitute part of this Proxy Statement.

We provide high-quality products that are safe and effective for their intended use.

2018 Shareholder Outreach

Our Board considers its relationship with our shareholders to be important to effective corporate governance. To ensure that the Board considers shareholder views on compensation, corporate governance, corporate responsibility and other significant matters, we maintain an active shareholder engagement program. Throughout the year, Management meets with our actively-managed, institutional shareholders, which own a majority of our shares. At every Board meeting, Management discusses topics raised by our shareholders and solicits Board input.

20   |   2019 Annual Meeting and Proxy Statement

BOARD AND DIRECTOR INFORMATION AND POLICIES

One area of focus for us and our shareholders is the alignment of pay and performance in a manner that enhances shareholder value. Our shareholders have historically expressed support for our performance goals and metrics.

Additionally, Management heard our shareholders express support for our corporate governance framework, Board membership and Board policies, including our tenure policies. Shareholder interest in environmental, social and governance matters has led to additional disclosures and progress in those areas with the Board's oversight.

Communicating with the Board

You may communicate with the Chairman of the Board or the independent directors as a group by sending a letter addressed to the Board of Directors, c/o Corporate Secretary, West Pharmaceutical Services, Inc., 530 Herman O. West Drive, Exton, Pennsylvania 19341. Communications to a particular director should be addressed to that director at the same address. Our Corporate Secretary maintains a log of all communications received through this process. Communications to specific directors are forwarded to those directors. All other communications are given directly to the Chairman of the Board who decides whether they should be forwarded to a Board committee or to Management for further handling.

Director Education

The Board believes shareholders are best served by Board members who are well versed in corporate governance principles and other subject matters relevant to board service. The Board arranges for a series of annual educational presentations on its calendar. Also, to encourage continuing director education, all directors may attend any director education programs they consider appropriate to stay informed about developments in corporate governance and the markets we serve. The Company reimburses directors for the reasonable costs of attending director education programs.

CORPORATE GOVERNANCE DOCUMENTS AND POLICIES

Corporate Governance Documents and Policies

Our principal governance documents are our Corporate Governance Principles, Board Committee Charters, director qualification standards, including our Independence Standards, and COBC. Aspects of our governance documents are summarized below. We encourage our shareholders to read our governance documents, as they present a comprehensive picture of how the Board addresses its governance responsibilities to ensure our vitality and success. The documents are available in the "Investors—Corporate Governance" section of our website at www.westpharma.com and copies of these documents may be requested by writing to our Corporate Secretary, West Pharmaceutical Services, Inc., 530 Herman O. West Drive, Exton, PA 19341.

Corporate Governance Principles

Our Board has adopted Corporate Governance Principles to provide guidance to our Board and its committees on their respective roles, director qualifications and duties, Board and committee composition, organization and leadership. Our Nominating and Corporate Governance Committee reviewed and significantly updated our Corporate Governance Principles to meet best practices in corporate governance during 2017. In 2018, the Committee confirmed that the Corporate Governance Principles address our current and long-term business needs. Our Corporate Governance Principles address, among other things:

•

Statements of the Board's commitment to high ethical standards, principles of fair dealing and high ethical standards

•

The requirement to hold separate executive sessions of the independent directors

•

The importance of robust executive succession planning and the role of directors in succession planning

•

The Board's policy on setting director compensation and director share-ownership guidelines

•

Guidelines on Board organization and leadership, including the number and structure of committees and qualifications of committee members

•

Guidelines on outside board memberships

•

Policies on making charitable contributions and prohibition of political contributions

•

Policies on access to Management

•

Requirements fostering leadership development by senior executives

•

Statements of our executive compensation philosophy and our independent auditor standards

•

Director orientation and education

•

Assessments of Board and Committee performance to determine their effectiveness

Code of Business Conduct

All our employees, officers and directors are required to comply with our COBC as a condition of employment. The COBC covers fundamental ethical and compliance-related principles and practices such as accurate accounting records and financial reporting, avoiding conflicts of interest, protection and proper use of our property and information and compliance with legal and regulatory requirements. The Board has adopted a comprehensive Compliance and Ethics Program, which was substantially updated in 2016, and was reviewed and reaffirmed in 2017 and 2018 as meeting the needs of our Company, its shareholders and other stakeholders. Susan A. Morris is our Chief Compliance Officer and reports directly to the Audit Committee of the Board on all compliance matters. Ms. Morris trains the Board on compliance matters and delivers regular reports on program developments and initiatives to the Audit Committee and no less than annually to the full Board.

Director Independence

Our Board has adopted a formal set of categorical Independence Standards. The Independence Standards meet or exceed the independence requirements of the NYSE corporate governance listing standards. Under the Standards, a director must have no material relationship with us other than as a director. The Independence Standards specify the criteria for determining director independence, including strict guidelines for directors and their immediate families regarding employment or affiliation with us, members of our senior Management or their affiliates. The full text of the Independence Standards may be found under the "Investors—Corporate Governance" section on our website at www.westpharma.com.

22   |   2019 Annual Meeting and Proxy Statement

CORPORATE GOVERNANCE DOCUMENTS AND POLICIES

The NCGC undertook its annual review of director independence in February 2019. As a result of this review, the NCGC recommended and the full Board concurred that no revision of the Independence Standards was required. Subsequently, the Board considered whether any relationships described under the Independence Standards between the Company and each individual director existed. The Board affirmatively determined that each of its non-employee directors is independent of the Company and Management as defined under the Independence Standards.

Related Person Transactions and Procedures

The Board has adopted written policies and procedures relating to the Nominating and Corporate Governance Committee's review and approval of transactions with related persons that are required to be disclosed in proxy statements under SEC regulations. A "related person" includes our directors, officers, 5% shareholders and immediate family members of these persons.

Under the policy, the NCGC reviews the material facts of all related-person transactions, determines whether the related person has a material interest in the transaction and may approve, ratify, rescind or take other action with respect to the transaction.

In approving a transaction, the Committee will consider, among other factors, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person's interest in the transaction.

The Committee reviews and pre-approves certain types of related person transactions, including certain transactions with companies at which the related person is an employee only, and charitable contributions that would not disqualify a director's independent status. The policy and procedures can be found in the "Investors—Corporate Governance" section of our website, www.westpharma.com.

We have no related person transactions required to be reported under applicable SEC rules.

Political Contributions and Lobbying

While we encourage directors, officers and employees to become involved in the political process in their individual capacity, including personal contributions to political campaigns, no West employee or director may conduct personal political activity on Company time or use Company funds, property or equipment for political activities. We comply with the laws related to contributing to, directly or indirectly, political organizations and government officials. Under our Corporate Governance Principles, the Board is responsible for overseeing the process used by the Company to ensure the Company's policy prohibiting political contributions is effectively implemented.

The Company made no political contributions in 2018, but does hold membership in recognized and reputable industry groups that may conduct lobbying activities.

Anti-Hedging and Pledging Policies

We prohibit directors, officers and employees from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, which would allow them to continue to own our common stock, but without the full risks and rewards of ownership. We also prohibit directors, executive officers and other senior employees from engaging in pledging or hypothecating our securities as collateral for a loan without demonstrating to the General Counsel that a director or officer has the financial capacity to repay the loan. It is expected that this exception would be permitted only in exceedingly rare circumstances. No pledging is permitted to cover margin debt. Additionally, no West securities may be held in a margin account by directors or officers because there is a risk of the shares being sold without consent. Directors and officers are prohibited from engaging in short sales or other short-position transactions in West securities as well.

Share Ownership Goals

Directors.    To encourage significant share ownership by our directors and further align their interests with the interests of our shareholders, directors are expected to acquire within three years of appointment, and to retain during their Board tenure, shares of our common stock equal in value to at least five times their annual retainer. All directors meet this requirement, including directors who are still within the three-year period to obtain the shares.

Officers.    Share ownership goals further align an officer's interests with those of our shareholders and encourage a long-term focus. Within five years of attaining their position, all executive officers must acquire shares of common stock with a value equal to designated multiples of their base salary. The Compensation Committee established a goal of six times base salary for the CEO and two times base salary for all other executive officers. A full description of the officer share ownership requirements can be found in our "Compensation Discussion and Analysis."

DIRECTOR COMPENSATION

Director Compensation

2018 Non-Employee Director Compensation

Board of Director compensation structure is reviewed annually by the Board of Directors in consultation with Pay Governance LLC ("Pay Governance"), our independent compensation consultant. After this review, it was determined that no changes were necessary to the compensation structure with respect to 2018. The structure that was in effect for all of 2018 is set forth below.

Compensation Item	Amount
Annual Retainers and Chair Fees
Board membership	$	80,000
Chairman of the Board	100,000*
Audit Committee Chair	20,000
Compensation Committee Chair	20,000
All Other Committee Chairs	10,000
Restricted Stock Units	160,000

*

Payable in 50% cash and 50% restricted stock, which vests 100% after one year, as elected annually by the Chairman.

The following table shows the total 2018 compensation of our non-employee directors.

2018 Non-Employee Director Compensation

Name	Fees Earned or Paid in Cash ($)		Stock Awards ($)		All Other Compensation ($)		Total ($)
Mark A. Buthman		100,000		160,074		18,837	278,911
William F. Feehery		90,000		160,074		13,318	263,392
Thomas W. Hofmann		80,000		160,074		20,757	260,831
Paula A. Johnson		90,000		160,074		26,926	277,000
Deborah L. V. Keller		80,000		160,074		1,731	241,805
Myla P. Lai-Goldman		80,000		160,074		6,793	246,867
Douglas A. Michels		100,000		160,074		20,525	280,599
Paolo Pucci		80,000		160,074		2,160	242,234
John H. Weiland		90,000		160,074		38,305	288,379
Patrick J. Zenner		130,000		210,074		32,560	372,634

Fees Earned or Paid in Cash

The amounts in the "Fees Earned or Paid in Cash" column are retainers earned for serving on our Board, its committees and as committee chairs and Chairman, as applicable. All annual retainers are paid quarterly. For Mr. Zenner this amount includes his cash fees for serving as Chairman of the Board. The amounts are not reduced to reflect elections to defer fees under the Director Deferred Compensation Plan. During 2018, Mr. Buthman, Ms. Keller and Mr. Michels deferred 100% of their fees.

Stock Awards

The amounts in the "Stock Awards" column reflect the grant date fair value of stock-settled RSU awards made in 2018 and the grant date fair value is determined under Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 718. In 2018, each continuing non-employee director was awarded 1,824 RSUs, with a grant date fair market value of $87.76 per share based on the closing price of our common stock on the award date, May 1, 2018. These awards had a grant date fair value of approximately $160,000. For a discussion on RSU grant date fair value, refer to Note 13 of the consolidated financial statements in our 2018 Annual Report.

RSUs are granted on the date of our Annual Meeting and fully vest on the date of the next Annual Meeting so long as a director remains on the Board as of that date. Generally, all unvested grants of equity forfeit upon termination. However, if a director

26   |   2019 Annual Meeting and Proxy Statement

DIRECTOR COMPENSATION

retires during the calendar year that he or she reaches our mandatory retirement age, the award will vest on a monthly basis through retirement.

Stock-settled RSUs are distributed upon vesting, unless a director elects to defer the award under the Director Deferred Compensation Plan. In 2018, all directors elected to defer their RSU awards, except for Mr. Weiland who did not defer. All awards are distributed as shares of common stock, as described below. When dividends are paid on common stock, additional shares are credited to each director's deferred stock account as if those dividends were used to purchase additional shares.

For Mr. Zenner, this column also includes the 584 shares of restricted stock received out of his $100,000 Chairman's annual retainer, which he elected to receive 50% in stock. The restricted stock, which had a grant date fair value of $85.62 per share, vests 25% per quarter and was equivalent to approximately 50% of his Chairman's retainer, or $50,000. These restricted shares are issued and outstanding, and, therefore, earn dividends. They are not eligible to be deferred or credited to the Director Deferred Compensation Plan. The remainder of this retainer was paid in cash.

The table below shows the number of outstanding stock awards held by each director at year-end. No directors have any outstanding options.

Outstanding Director Stock Awards at Year-End 2018

Board Member	Unvested Restricted Stock Awards (#)		Vested Annual Stock Awards (#)		Unvested Annual Deferred Stock and Stock-Settled RSU (#)		Total Outstanding Stock Awards (#)

Patrick J. Zenner		292		58,141		1,829		60,262

All Other Compensation

The amounts in the "All Other Compensation" column are Dividend Equivalent Units ("DEUs") credited to accounts under the Director Deferred Compensation Plan and a $3,000 charitable donation made by Paula Johnson, which was matched by the Company's foundation.

Director Deferred Compensation Plan

All non-employee directors may participate in the Director Deferred Compensation Plan, which permits participants to defer all or a part of their annual cash compensation until their Board service terminates. Deferred fees may be credited to a "stock-unit" account that is deemed invested in our common stock or to an account that earns interest at the prime rate of our principal commercial bank. Stock-unit accounts are credited with DEUs based on the number of stock units credited on the dividend record date.

The value of a director's account balance is distributed on termination of Board service. The value of a director's stock-unit account is determined by multiplying the number of units credited to the account by the fair market value of our common stock on the termination date.

RSUs that a director elects to defer (and all shares of deferred stock) are distributed in shares of stock. Pre-2014 stock units may be distributed in cash in lieu of stock, if a director made an election in 2013. All post-2013 stock units are only distributable in stock. Partial shares are distributed in cash.

Directors may receive their distribution as a lump sum or in up to ten annual installments. Separate elections apply to amounts earned and vested before January 1, 2005 and amounts earned and vested after December 31, 2004, which solely applies to Mr. Zenner. If a director elects the installment option, the cash balance during the distribution period will earn interest at the prime rate of our principal commercial bank and deferred stock and stock-settled units will be credited with DEUs until paid.

The following table summarizes the amounts credited to each Director Deferred Compensation Plan account as of December 31, 2018: All values on the following table are determined by multiplying the number of stock units or shares of deferred stock, as

Executive Summary: 2018 Performance at a Glance

West's long-term business strategy includes growing and expanding our products and services to meet the unique needs of our customer groups, operating with excellence to drive efficient utilization of our global manufacturing footprint and building the capabilities of our team to address current and future business needs. This strategy will drive our long-term financial construct to grow revenue by six to eight percent annually, and achieve improved profitability year-over-year, in turn creating a sustainable business that will meet the needs of our customers, patients, shareholders, and employees. Our five-year Total Shareholder Return ("TSR") was 207%.

Highlights of our 2018 performance include the following:

•

Full-year reported net sales of $1.717 billion, which reflects 7.4% growth over the prior year. At constant currency, organic sales growth was 5.6%.

While the Proprietary Products segment gross profit margin expanded by 80 basis points, Contract-Manufactured Products segment gross profit margin declined by 280 basis points due to unabsorbed overhead from plant consolidation activities, start-up costs associated with the launch of new programs and unfavorable sales mix.

•

Full-year 2018 reported-diluted EPS was $2.74, compared to $1.99 last year. Full-year 2018 adjusted-diluted EPS was $2.81, compared to $2.78 in the prior year. Tax benefits from stock-based compensation contributed $0.19 to full-year 2018 reported and adjusted-diluted EPS, compared to $0.44 to full-year 2017 adjusted-diluted EPS.

•

Full-year operating cash flow was $288.6 million, representing a 9.6% increase over 2017 operating cash flow of $263.3 million.

•

Capital expenditures in 2018 were $104.7 million, a 20% reduction compared to 2017 capital expenditures of $130.8 million.

In 2018, we continued to make strategic investments to drive the future growth for our business:

•

$40.3 million investment in research and development, continuing our focus in device development, elastomeric packaging component enhancements and new formulation development

•

Capital investments in Waterford, Ireland; Dublin, Ireland; and Puerto Rico

2018 Committee Actions and Rationale

Executive Compensation Actions & Results

Reaffirmed West's compensation philosophy of pay-for-performance that aligns executives' incentive compensation with Company performance and stakeholder interests on both a short- and long-term basis, without promoting excessive risk

Further refined the Company's AIP to drive stronger alignment with our business objectives

Revised officer stock ownership requirements requiring officers who have not met their share ownership goals after five years to hold 100% of net shares resulting from any equity award vesting or stock option exercise and have 50% of their annual bonus paid in stock until ownership guideline is met. We also modernized the definition of shares deemed to be beneficially owned.

Eliminated AIP incentive share matching program for officers, effective January 1, 2019

Reaffirmed continuation of the two-comparator group approach used for executive and director pay and pay-for-performance benchmarking

Aligned the effective date of 2018 salary increases for Officers, including the CEO, to March from May (which is the same as all other salaried employees)

Reviewed services and relationship with our Compensation Committee independent consultant (Pay Governance). Based on that review we renewed their contract for a three-year period ending in 2021

Governance and Compensation

Executive Compensation Philosophy

Our compensation philosophy is to provide competitive executive pay opportunities tied to our short-term and long-term success. This overriding pay-for-performance approach enables us to attract, motivate and retain the type of executive leadership that will help us achieve our strategic objectives and realize increased shareholder value. To achieve these goals, we have adopted the following program objectives:

•

Reward achievement of both operating performance and strategic objectives

•

Align the interests of West's leaders to those of our investors by varying compensation based on both short-term and long-term business results and delivering a large portion of the total pay opportunity in West stock

•

Differentiate rewards based on performance against business objectives to drive a pay-for-performance culture, with a major portion of executive pay based on achievement of financial performance goals

•

Promote a balanced incentive focus that does not encourage unnecessary or unreasonable risk-taking

•

Be market-competitive to attract and retain highly qualified senior leaders needed to drive a global enterprise

Best Practices that Support Our Executive Compensation Philosophy

The Compensation Committee oversees the governance, design and administration of our executive compensation programs and evaluates these programs against competitive practices, legal and regulatory developments and corporate governance trends.

We continue to incorporate leading design and governance practices into our compensation programs.

What We Do

What We Don't Do

✓ Target TDC at the 50th percentile of our comparator group companies ✓ Provide a majority of compensation through performance-based incentives ✓ Conduct realizable-pay-for-performance analyses of our CEO compensation and use tally sheets to provide additional information on the appropriateness and function of our executive pay ✓ Incorporate a "double-trigger" feature requiring termination of employment, in our CIC agreements, which also do not contain tax gross-ups ✓ Require executive officers to meet West stock ownership guidelines and to take a portion of their annual incentive bonus in West shares until ownership guidelines are met ✓ Cancellation or recovery of incentive compensation based on achievement of specified financial results that are the subject of a subsequent restatement or amounts determined to have been inappropriately received due to fraud, misconduct or gross negligence ✓ Incorporated claw-back provisions on amounts determined to have been inappropriately received due to fraud, misconduct or gross negligence ✓ Engage with an independent consultant to review compensation programs and decisions

✗ No hedging, pledging or engaging in any derivatives trading with respect to our common stock ✗ No repricing or exchange of awards without shareholder approval ✗ No individual severance agreements for executive officers other than CEO ✗ No excise tax gross-ups ✗ No guaranteed incentive payouts ✗ No accelerated vesting of equity awards for executive officers ✗ No above-market returns on deferred compensation plans ✗ No executive perks

Say-on-Pay

Each year, we hold a shareholder "Say-on-Pay" advisory vote to assess the support for the compensation of our NEOs as disclosed in our Proxy Statement. In 2018, our Say-on-Pay proposal received more than 96% support, consistent with each of the previous three years.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Compensation Program Design

The specific elements of West's executive compensation programs are:

Element	Objective	Type	Key Features
Base Salary	Fair and competitive compensation to attract, retain and reward executive officers by providing a fixed level of cash compensation tied to experience, skills and capability relative to the market	Cash	• Annual cash compensation that is not at risk • Targeted at the 50th percentile of our compensation comparator groups, with variations based on experience, skills and other factors • Reviewed annually with adjustments considered based on level of pay relative to the market, individual and Company performance
Short-Term Annual Incentive	Focuses executives on annual results by rewarding them for achieving key budgeted financial targets Links executives' incentives with those of shareholders by promoting profitable growth Helps retain executives by providing market-competitive compensation	Cash	• Annual cash incentive based on achievement of key business metrics: Revenue, EPS, OCF and Gross Profit • Annual award payouts may vary from 0% to 150% of the targeted award based on achievement • Threshold performance required to achieve payment is 85% of target performance goal
Long-Term Incentive Compensation (100% Equity)	Aligns executives' interests with those of shareholders by linking compensation with long-term Company and stock price performance that benefits our employees and shareholders Serves as both an incentive and retention vehicle for executives through multi-year performance share units (PSUs) and stock options Promotes a balance of longer-term risk and reward, without encouraging unnecessary or unreasonable risk taking	Annual PSU Grant (50% of long-term incentive compensation award fair market value ("FMV"))	• PSUs are settled three years from the grant date based on business results over a three-year performance period • PSUs (inclusive of DEUs) are paid in shares of Company common stock upon vesting • The number of shares (inclusive of accrued DEUs) that may be earned over the performance period is based on achievement against target of two equally weighted measures—CAGR and ROIC—and can range from 0% to 200% of the target award • Threshold performance required to achieve payment is 70% for each target performance metric
		Annual Nonqualified Stock Option Grant (50% of long-term incentive compensation award FMV)	• Annual awards vest in four equal annual installments and expire 10 years from the grant date • Option exercise prices are at or exceed the closing price on the date of grant • DEUs are not provided on options
		Time-Vesting Restricted Stock Units and Retention Options	• Typically, only used to attract talented executives who are foregoing compensation from prior employer • Provides a retention tool for new executives, provides an immediate ownership stake in the Company and alignment with shareholders through an incentive to increase the stock value

COMPENSATION DISCUSSION AND ANALYSIS

Factors Used in the Compensation Process

Compensation Committee

The Compensation Committee (or the "Committee" in this section of the Proxy Statement) reviews and approves the compensation elements and the compensation targets for each of our executive officers. The Compensation Committee also makes determinations with respect to the AIP as it relates to our executive officers, including the approval of annual performance goals and subsequent full-year achievement against those goals. It administers all elements of the Company's LTI plan, and approves the benefits offered to executive officers. Compensation decisions for the CEO are reviewed and approved by the full Board of Directors.

The Committee uses its judgment in making decisions about individual compensation elements and total compensation for our NEOs. This judgment is informed by competitive market data but primarily is focused on each NEO's performance against his or her individual performance objectives, as well as the Company's overall financial performance and the financial performance of the function or areas of operational responsibility for each NEO.

In making its decisions, and with guidance from our independent compensation consultant, Pay Governance, the Committee uses several resources and tools, including competitive market information, compensation trends within our comparator groups, where available, and realizable pay versus performance analysis.

The Committee also reviews "tally sheets" for each of our executive officers as one of the tools to help assess the alignment of NEO pay with our performance and compensation philosophy. The tally sheets include salary, equity and non-equity incentive compensation and the value of compensation that would be paid in various termination scenarios. The tally sheets help the Committee to understand the magnitude and interplay of the various components of our compensation programs.

Finally, the Compensation Committee evaluates the Company's compensation programs on an annual basis to ensure that our plans do not induce or encourage excessive risk-taking by participants.

Management

Our CEO and CHRO annually review with the Compensation Committee the performance of each executive officer and recommend to the Committee annual merit salary adjustments and any changes in annual or long-term incentive opportunities or payouts for these officers, except for the CEO. The Committee considers Management's recommendations along with data and recommendations presented by Pay Governance.

The CHRO serves as the liaison between the Compensation Committee and Pay Governance, providing internal data on an as needed basis so that Pay Governance can produce comparative analyses for the Compensation Committee. In addition, the Company's Human Resources, Finance and Legal Departments support the work of the Compensation Committee by providing information, answering questions and responding to various requests of Committee members as required.

Independent Compensation Consultant

The Committee has engaged Pay Governance as its independent consultant to assist the Committee in evaluating the executive compensation program. The consultant provides no services to us other than advice to the Committee on executive compensation matters (including CIC matters) and to our Nominating and Corporate Governance Committee on director compensation. In 2018, the Compensation Committee reaffirmed Pay Governance to be independent from the Company under the applicable NYSE and SEC regulations.

During 2018, Pay Governance performed the following tasks for the Committee:

✓

Provided competitive market data for the compensation of the executive officer group and provided input to the Committee regarding officer pay recommendations (including the CEO)

✓

Prepared analysis of existing compensation and recommendations related to the compensation to be paid to executive officers hired in 2018

✓

Assessed incentive plan performance difficulty and provided related context regarding performance metric selection

✓

Updated the Committee on executive compensation trends and regulatory developments

✓

Prepared a realizable pay analysis for the CEO

✓

Assisted with the Company's review of our comparator groups

✓

Provided input on compensation program design and philosophy

✓

Monitored trends and analysis in executive and equity compensation

COMPENSATION DISCUSSION AND ANALYSIS

External Benchmarking

In support of our compensation philosophy, we reference the median compensation values of two compensation comparator groups, which we refer to as the "Business Segment Group" and the "Broad Talent Market Group." Data from both the Business Segment Group (which generally is applicable to the CEO and CFO) and Broad Talent Market Group are used to determine competitive pay practices for our CEO and executive officers in a wholistic manner.

The Business Segment Group is composed of public companies with operational and customer characteristics similar to our own business operations. These companies initially are identified by Pay Governance and then approved by the Committee with input from Management based on the following criteria: (1) size (approximately one-half to two times our annual revenues); (2) industry (healthcare equipment/supplies, industrial manufacturing and life sciences tools/services); and (3) operating structure such as:

•

Global footprint with multi-plant manufacturing capabilities

•

Similar raw materials and products (elastomers, plastics, metals), and similar intellectual property profile

•

Similar customer characteristics (complex sales cycle, quality requirements, regulatory requirements)

The Broad Talent Market Group is a larger and broader sampling of size-appropriate companies that participate in the Willis Towers Watson annual executive compensation database. Unlike the Business Segment Group, the Compensation Committee does not select individual members of the Broad Talent Market Group. Companies within the Broad Talent Market Group have annual revenues between 500 million and four billion U.S. Dollars and operate in industries that are similar, but not identical to our own industry. Industries included are: Chemicals and Gases; Electrical and Scientific Equipment and Components; Medical Supplies and Equipment; and, Pharmaceutical and Biotechnology.

Given our size and business portfolio, it is challenging to identify a robust sample of appropriate market compensation peers that fit conventional criteria. Therefore, we believe that using a balance of business and talent market references that reflect companies with which we compete for business and capital, and more broadly, those with which we compete for talent, provides the Committee with decision-quality data and context, and reasonably represents our labor market for executive talent.

Below is a chart that lists each company included in the 2018 Business Segment Group and some key data the Committee considered in making the selection for inclusion. The data below are generally from 2017 public annual reports with respect to each company, with market capitalization data as of December 31, 2018. All amounts are in millions of U.S. Dollars.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Officer Stock Ownership Guidelines

Within five years of appointment, Officers are expected to acquire shares of West common stock with a value equal to the following:

CEO	Other NEOs
6 times base salary	2 times base salary

In 2018, the Compensation Committee reviewed and updated the ownership guidelines to further clarify and align to market practice. The Committee reviewed peer group guidelines and consulted with Pay Governance to identify market practice. The following illustrates the type of equity holdings that count towards stock ownership requirements:

What Counts	What Does Not Count
✓ 100% of West shares owned personally or by members of the immediate family sharing the same household ✓ 100% of vested shares of West stock held in a qualified or non-qualified deferred compensation plan ✓ 60% of unvested RSUs ✓ Unrestricted bonus stock, not a part of matching contributions but subject to matching contribution holding requirements	✗ Unvested stock options and PSUs ✗ Unexercised, vested stock options ✗ Restricted bonus stock subject to matching contribution holding requirements

Until individual share ownership goals are met, executives will receive 25% of their annual bonus in West stock. If after five years the required share ownership has still not been met, the officer must hold 100% of net shares resulting from any equity award vesting or stock option exercise and will have 50% of their annual bonus paid in stock.

As of December 31, 2018, other than Ms. Flynn and the now-retired Mr. Federici, neither the CEO nor the other NEOs had yet met the holding requirements; however, all are within the five-year attainment period. Mr. Green is targeted to meet the guideline in 2019. Mr. Montecalvo has until 2021 to meet the guidelines, and Mr. Birkett and Mr. Abraham have until 2023.

The Impact of Business Results on our 2018 Incentive Plans

We have designed our compensation programs to align the pay of our senior executives with both short-term and long-term financial results and the performance of our stock. As such, the majority of pay for our CEO and other NEOs is performance-based and is impacted by our financial results and stock price performance. During 2018, 17% of Mr. Green's TDC was variable based on short-term business performance and 66% was based on long-term goals. For our other executives, approximately 23% of their TDC was variable based on short-term business performance and 42% was based on long-term goals

As a result of below target financial performance in 2018, we paid out less than 100% on both our short- and long-term incentive plans.

Our AIP paid out at 93.1% of target for the Corporate plan, and at 93.8% and 87.3% for the Commercial and Global Operations plans, respectively, as our results were slightly behind target for all performance metrics. Specifically, our constant-currency sales growth of 5.6% was lower than our annual growth expectation of between 6% to 8%. Also, the mix of products sold favored our Contract-Manufactured Products segment, which generates a lower profit margin than our Proprietary Products Segment, and ultimately resulted in below target consolidated gross profit and earnings per share.

Our LTI plan is equally based on achieving CAGR on sales and ROIC targets. The payout for the 2016-18 performance period was 49.39% as our CAGR for this period was 6.55% (versus a target of 9.80%) and did not meet the minimum threshold for payout on 50% of the target award. Our ROIC for this performance period was 12.21% versus a target of 12.30%.

COMPENSATION DISCUSSION AND ANALYSIS

Incentive Compensation: Important Facts about our Incentive Targets

As in previous years, the Compensation Committee evaluates and decides upon the appropriate financial measures using the following principles:

•

Alignment with our growth strategy, supporting profitable growth while generating significant cash from operations; and driving long-term value creation for our customers, employees, investors and shareholders

•

Provide a clear line of sight to the stated goals of the Company, so that the targets are clearly understood and can be affected by the performance of our executives and employees

•

Attainable targets, but with a sufficient degree of "stretch" to support growth

•

Consistent with market practice

•

Currency neutral on revenue in order to measure the underlying results of the business and help to ensure business leaders are making decisions that drive long-term sustainable growth rather than addressing short-term currency fluctuations or items impacting comparability

•

We make limited adjustments to metrics. At times, adjustments may need to be made when calculating results for awards such as for changes in financial accounting reporting regulations and costs and other financial implications associated with corporate transactions.

We continually test the robustness of our incentive targets and performance payout curves. The setting of our performance payout curves considers the following:

•

Performance levels necessary to achieve our long-term goals and deliver superior shareholder returns

•

The likelihood of achieving various levels of performance based on historical and anticipated future results

•

Metrics, program designs and results at companies in our Business Segment Group

•

Performance relative to our Business Segment Group and anticipated industry trends

The Compensation Committee annually reviews the target setting process to ensure adherence to our principles. This analysis is aided by a retrospective review of our performance compared to that of our competitors and is performed annually by the Board's independent compensation consultant, Pay Governance.

For 2018, we measured the following key financial metrics:

Plan	Financial Metric	Rationale
	Earnings per Share	A comprehensive measure of income and provides an emphasis on profitable growth while focusing managers on expense control
	Consolidated Revenue	Provides a clear line-of-sight target for all members of our executive officer team as we strive to create value by growing our sales
AIP	Operating Cash Flow	Provides a focus on generating cash in the short term to fund operations, research and capital projects and focuses managers on cash generation
	Consolidated Gross Profit	Provides focus on targeting efforts on higher value product growth and improving operating efficiencies in our production facilities
LTI	Compounded Annual Growth Rate	Provides an objective measure of revenue growth
	Return on Invested Capital	Drives efficient and disciplined deployment of capital

Note: All metrics are measured at actual foreign currency exchange ("FX") rates except for Consolidated Revenue, which is measured at budget FX rates to remove the impact of currency fluctuations and allow for a year-to-year comparison.

COMPENSATION DISCUSSION AND ANALYSIS

Our Annual Incentive Compensation

Target Setting

At the beginning of each year, the Compensation Committee and the Board review and approve West's annual business objectives and set the metrics and weightings for the annual incentive program to reflect current business priorities. These objectives translate to targets for West and for each business unit for purposes of determining the target funding of the AIP. Performance against business objectives determines the actual total funding pool for the year, which can vary from 0% to 150% of total target incentives for all executives.

Our reported results may be adjusted when comparing to AIP targets for unusual events outside the control of management including changes in accounting standards, tax regulations and currency devaluations. We may also exclude certain transactions such as material acquisition or disposition costs including restructuring charges particularly if these items were not included in the performance target. All adjustments are reviewed with and approved by the Compensation Committee. For 2018, the adjustments made were:

•

Revenue is reflected at budgeted foreign currency exchange rates

•

EPS excludes $0.08 for restructuring and related charges, $0.02 for the Argentina currency devaluation charge, and a ($0.03) net tax benefit due to the impact of tax law changes

•

EPS also excludes an unbudgeted tax benefit of $0.19 on stock compensation and $0.12 for the unbudgeted favorable impact of tax rate reduction associated with the U.S. Tax Cuts and Jobs Act of 2017 signed into law on December 22, 2017 (the "2017 Tax Act")

Target Awards

The target annual incentive awards for our NEOs are set as a percentage of base salary. Target awards are reviewed annually to ensure alignment with our compensation philosophy to target each compensation element and TDC at the market median. Variances from this goal are based on an evaluation of competitive market data, internal equity considerations and individual performance. Our payout curve is structured to reflect our philosophy that Management should be rewarded for meeting or exceeding goals and payouts diminish or are withheld when targets are missed.

The formula to determine each NEO's AIP total potential payment is as follows:

2019 Annual Meeting and Proxy Statement   |   39

COMPENSATION DISCUSSION AND ANALYSIS

The payout factor is a pre-established multiplier that corresponds, on a sliding scale, to the achievement percentage of the AIP target objective so that if actual performance is less than target, the multiplier decreases on a sliding scale based on the achievement percentage and is based on the following chart:

Achievement %	Payout factor
<85%	0
85%	50.0	%
95%	83.3	%
100%	100.0	%
105%	116.7	%
110%	133.3	%
³115%	150.0	%

Achievement that falls between any two achievement percentages is straight-line interpolated. The Compensation Committee has discretion to positively or negatively adjust payout to account for exceptional circumstances.

The Compensation Committee reviews the AIP scoring and adjustments made and approves the AIP funding level.

Financial Measures and Adjustments

EPS growth for AIP purposes differs from the EPS reported in our Earnings Release under U.S. GAAP and is best explained by reconciling the results used for calculating AIP payments to U.S. GAAP and the Earnings Release. A reconciliation of the financial measures used for the AIP to our Earnings Release financials allows for a meaningful comparison. The following table contains unaudited reconciliations of 2018 U.S. GAAP Consolidated Revenues, OCF and Reported Diluted EPS to Adjusted Revenue, Adjusted OCF, and Adjusted Diluted EPS for AIP purposes relating to the 2018 AIP Performance Metrics and Achievement Table above. There were no other adjustments.

Our Long-Term Equity Incentive Compensation

Target Setting

The targets for West's PSUs are set at the beginning of each three-year performance period, taking into account West's financial model shared with investors and the annual budget as approved by the Board. At the end of the three-year period, the score is calculated based on results against the predetermined targets equally weighted. We use CAGR and ROIC as our performance measures for determining PSU payouts. Each metric is weighted equally because we believe CAGR and ROIC are equally important in creating shareholder value over the long-term.

The metrics, goals and weightings for the performance period 2018—2020 are:

2018—20 PSU Performance Period Targets

Metric	Threshold			Target			Maximum (200%)
CAGR		4.90	%		7.00	%		10.50	%
ROIC		9.45	%		13.5	%		20.25	%

2019 Annual Meeting and Proxy Statement   |   41

COMPENSATION DISCUSSION AND ANALYSIS

Target Awards

LTI compensation opportunities for our executives, including the NEOs, are entirely equity-based. Each NEO's annual target award is split into two equal amounts, which are then used to determine the number of stock options and PSUs awarded to the executive. The value of each stock option is determined under the Black-Scholes valuation method. The value of each PSU is determined by our stock price at the grant date. The actual or realized value of these awards in future years will vary from this target amount based on share price, ROIC and CAGR performance over time. Please refer to Note 13 of our annual report on Form 10-K for a complete discussion of our stock-based compensation.

The use of stock options is intended to align our executives' longer-term interests with those of our shareholders because options deliver value to the executive only when and to the extent that share price exceeds the exercise price of the option. Therefore, options provide a strong performance-based link between shareholder value and executive pay.

PSUs entitle the recipient to receive common shares based on achievement of three-year CAGR and ROIC targets.

The value of each NEO's long-term grant is determined by the Committee based on its review of peer-group market data, the executive's role and responsibilities, his or her impact on our results, advancement potential, retention considerations and, in principle, is targeted to the market median.

Performance Share Units

The number of shares earned under the PSUs is based on achievement of CAGR and ROIC targets. Each PSU award agreement contains a target payout for the recipient. The number of shares an executive earns at the end of a performance period is calculated by multiplying the target number of PSUs awarded at the beginning of the period times the applicable "payout factor" for each performance metric by the weighting for that performance metric.

Performance Achievement (% of Target)			Payout factor
	<70	%		0
	70	%		50	%
	85	%		75	%
	100	%		100	%
	110	%		120	%
	125	%		150	%
	³150	%		200	%

The Compensation Committee approves the determination of actual achievement relative to pre-established targets and the number of PSUs is adjusted up or down from 0% to 200% based on the approved actual achievement. The Committee reserves the right to negatively or positively adjust payouts under exceptional circumstances.

Equity Award Grant Practices

Under the Committee's equity-based awards policy and procedures, equity awards to NEOs normally are made once per year. The Company's policy on equity grants contains rules on determining (1) the grant date of equity awards (at least two business days following the release of our annual results for the preceding fiscal year) and (2) the exercise price of stock options granted by the Committee (which must be at least equal to the closing price of our stock on the grant date).

In the first quarter of each year, the Compensation Committee meets to determine CEO and Executive Officers' pay decisions for base salary, AIP and LTI award grants reflecting both prior year performance and appropriate positioning versus the representative peer group(s).

2018 Compensation Decisions for our CEO

Our compensation strategy supports West's business imperatives. It is designed to ensure:

•

That executives balance short-term objectives against long-term priorities

•

Alignment with stockholder interests

•

The Company is able to attract and retain the leadership needed to deliver strong results

Pay decisions were made in the context of our financial performance relative to our goals while also taking into account (1) the organizational transformation made in 2016 from a regional, product-led management approach to a market-led globally integrated enterprise, and (2) the steps taken to strengthen West's position for the future.

The Chair of the Compensation Committee works directly with the Committee's Compensation Consultant to provide a decision-making framework for use by the Committee in determining incentive plan payouts and setting target compensation opportunities for the CEO. This framework considers, among other things:

•

Assessment of the CEO's performance against objectives in the prior year, both qualitative and quantitative

•

Progress against strategic objectives

•

West's total performance over a multi-year period

•

Competitive benchmark analysis, and other relevant information

COMPENSATION DISCUSSION AND ANALYSIS

Other Compensation Practices

Post-Employment Compensation Arrangements

During 2018, NEOs hired on or before January 1, 2017 (Mr. Green, Ms. Flynn, Mr. Montecalvo and Mr. Federici) participated in our defined benefit retirement plan and all NEOs were eligible to participate in our defined contribution retirement plan for all employees. In addition to the standard benefits available to all eligible employees, we maintain nonqualified retirement plans in which these executives participate in the same capacity as eligible salaried employees.

All tax-qualified defined benefit plans have a maximum compensation limit and a maximum annual benefit, which limits the benefit to participants whose compensation exceeds these limits. The nonqualified retirement plans offered by the Company provide benefits to key salaried employees, including each NEO, using the same benefit formulas as the tax-qualified plans but without regard to the compensation limits and maximum benefit accruals for tax-qualified plans.

We also provide our NEOs with benefits upon termination in various circumstances, as described under "Estimated Payments Following Termination" and "Payments on Termination in Connection with a Change-in-Control" sections below.

We believe that our existing arrangements help executives remain focused on our business in the event of a threat or occurrence of a CIC and encourage them to act in the best interests of the shareholders in assessing and implementing a transaction. With regard to Mr. Green's severance arrangement, we believe severance pay is necessary to attract and retain a quality CEO candidate and that the benefits of securing a release of claims, cooperation and non-disparagement provision from Mr. Green upon an involuntary termination are significant.

Beginning with agreements entered into after 2010, the Company eliminated excise tax gross-ups and single-triggers under these types of agreements. With Mr. Federici's retirement, no remaining current agreement includes an excise tax gross-up or permits payment in the event of voluntary termination without good reason. All current agreements include a cutback in payments and benefits if the NEO would be in a more favorable after-tax position and no benefits upon a voluntary resignation that is not due to "good reason."

Mr. Green has a separate employment agreement that contains many similar provisions to the CIC, but also includes other terms and conditions that resulted from negotiations relating to compensation and termination.

The terms and conditions of all these agreements are described in more detail in the Compensation Tables section of this Proxy Statement.

Personal Benefits

The benefits provided to our NEOs are generally the same as or consistent with those provided to our other salaried employees.

Retention Cash

Occasionally, the Committee pays signing and retention bonuses in cash. These bonuses may have repayment obligations. The primary purpose of these payments is to replace equity or cash payments a new officer will forfeit from his/her former employer upon joining West.

Realizable Pay Analysis

The Committee works with Pay Governance to review pay granted and realizable by the CEO in the context of West's performance. Realizable pay is calculated using actual bonuses earned, end of period stock values and in-the-money value of stock options granted during the year. It takes a retrospective look at pay versus performance. The analysis showed that there was a high correlation between the realizable pay earned by our CEO and the Company's performance as measured by TSR, CAGR, ROIC and similar financial metrics compared to other members in our Business Segment Group. The Committee determined this analysis is consistent with its pay-for-performance philosophy and that our incentive plans are operating as intended.

Risk Considerations in Our Compensation Programs

The Committee has reviewed our compensation policies and practices for our officers and employees and concluded that any risks arising from these policies and programs are not reasonably likely to have a material adverse effect on the Company. The Committee believes that the mix and design of the elements of our compensation program are appropriate and encourage executive officers and key employees to strive to achieve goals that benefit the Company and our shareholders over the long term.

2019 Annual Meeting and Proxy Statement   |   47

COMPENSATION DISCUSSION AND ANALYSIS

Our compensation policies and procedures are applied uniformly to all eligible participants. By targeting both company-wide and business-unit performance goals in our annual bonus plans and long-term compensation, we believe we have allocated our compensation between base salary and short- and long-term target opportunities in a way that does not encourage excessive risk-taking by our employees.

Policy on Hedging and Pledging

We prohibit directors, officers and employees from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, which would allow them to continue to own our common stock, but without the full risks and rewards of ownership. We also prohibit directors, NEOs and other senior employees from engaging in pledging, short sales or other short-position transactions in our common stock.

Impact of Tax and Accounting Treatment

The Compensation Committee selects compensation vehicles that will, in its view, create the best link between pay and performance. Generally, the accounting and tax treatments of executive compensation has not been a significant factor in the Compensation Committee's decisions regarding the amounts or types of compensation paid. Our programs have been designed, where appropriate and consistent with our compensatory goals to maximize deductibility under applicable tax law. The Committee also considers the impact of changes to accounting regulations and tax law, such as the Tax Cut and Jobs Act of 2017, when reviewing elements of compensation, including equity and other performance-based awards.

(1)

These amounts represent the minimum, target and maximum awards under the AIP. The amounts are not reduced to reflect any elections to defer receipt of an executive's cash bonus or bonus shares under any deferred compensation plan.

(2)

These amounts represent PSUs that may vest depending on attainment of performance targets over a three-year performance period. The amounts in this column are not reduced to reflect any elections to defer receipt of an executive's PSUs under any deferred compensation plan.

(3)

The RSUs listed in this column represent incentive shares vesting 100% after four years for Mr. Green and Mr. Montecalvo and retention RSU awards for Mr. Birkett and Mr. Abraham. Mr. Birkett's RSU vests 25% annually starting on first anniversary of award, while Mr. Abraham's award vested one-third annually starting on first anniversary of award. The grant date of the incentive shares was February 20, 2018, when the grant date fair value was $89.64 per share.

(4)

This column consists of the fair value of options and stock awards granted during 2018. The per-option grant date fair value (under FASB ASC Topic 718) was $19.95 for all options and $89.64 per share for all PSUs granted on February 20, 2018. For the assumptions made in determining grant date fair values, refer to Note 13 to the consolidated financial statements included in our 2018 Annual Report.

(1)

All options are exercisable in 25% annual increments beginning one year from the grant date, except as noted in footnote 5 for Mr. Green and footnote 7 for Mr. Montecalvo.

(2)

Retention restricted stock or RSUs granted to Mr. Green, Mr. Birkett, Mr. Montecalvo and Mr. Abraham upon hire. Mr. Birkett's award vests 25% per year starting on first anniversary of grant. Vesting of awards for Mr. Green, Mr. Montecalvo and Mr. Abraham are discussed in footnotes 5, 6, 7 and 8 respectively. All RSUs granted also earn DEUs, which are subject to the same vesting schedule as the underlying RSU.

(3)

Bonus Incentive Awards are time-vesting restricted incentive shares granted when an NEO elects to receive a portion of his or her bonus in stock, whether or not the bonus is deferred under the Employee Deferred Compensation Plan. The restricted incentive shares were granted on February 17, 2015 (Ms. Flynn), February 23, 2016 (Mr. Green), February 14, 2017 (Mr. Green and Mr. Montecalvo) and February 20, 2018 (Mr. Green and Mr. Montecalvo) and, in each case, are 100% vested four years from the grant date if the bonus share to which the incentive share relates has not been sold and the employee has not terminated employment. The incentive shares will also vest 25% per year upon retirement, but no NEO who currently has outstanding incentive shares is yet eligible to retire. Unvested incentive shares are forfeited on employment termination. Dividends are paid on all unvested restricted shares and reinvested as additional stock subject to the same vesting requirements as the underlying shares. The market value of all restricted shares and RSUs is based on the closing price of our common stock on December 31, 2018 of $98.03.

COMPENSATION TABLES

(4)

Except as noted for Mr. Green, Mr. Birkett, Mr. Montecalvo and Mr. Abraham, who received some PSUs on their hire dates, these PSUs were awarded on February 23, 2016, February 21, 2017 and February 20, 2018 and each covers a three-year performance period. PSUs were granted on their respective hire dates to Mr. Green, Mr. Birkett, Mr. Montecalvo and Mr. Abraham. This table includes as outstanding the 2016-18 PSUs awards that were distributed in February 2019, because the performance is not actually determined and certified by the Committee until the first quarter of 2019. The 2017 and 2018 awards will be earned (if at all) on December 31, 2019 and December 31, 2020, respectively, subject to the satisfaction of the applicable performance criteria and generally subject to the recipient's continued employment through those dates. As required by the SEC's disclosure rules, because the performance for the most recently completed fiscal year was less than 100%, the number of PSUs shown assumes that a target payout of 100% will be achieved for all three awards. Fair market value of the unearned PSUs is based on the closing price of our common stock on December 31, 2018 of $98.03. The amounts are not reduced to reflect any elections to defer receipt under the Employee Deferred Compensation Plan.

(5)

The options denoted as Hire Grant 1 for Mr. Green in the table above and 30,499 of the shares of restricted stock granted to Mr. Green vested 57.1% on April 24, 2018. The remaining 42.9% of these retention options and shares will vest on April 24, 2020, but would be forfeited if employment is terminated for any reason other than death or disability before that date. The options denoted as Hire Grant 2 for Mr. Green were 25% vested upon the grant date and the remaining options will vest in 25% increments on February 24th of each following year. The options denoted as Hire Grant 3 for Mr. Green will vest in 25% increments on February 23rd of each year following grant. These option vesting schedules are consistent with the schedules for active employees as of February 2014 and 2015, for each respective option. All other option grants are subject to the vesting schedules set forth in footnote 1 above.

(6)

The RSUs granted to Mr. Birkett will vest 25% on the anniversary of the grant provided that he remains employed by the Company, terminates with "good reason," is terminated without "cause" by the Company, dies or becomes disabled. The options awarded upon hire will vest in 25% increments on the anniversary of the grant.

(7)

The RSUs granted to Mr. Montecalvo on his hire date will vest 100% on September 26, 2021 provided that he remains employed by the Company, terminates with "good reason," is terminated without "cause" by the Company, dies or becomes disabled. The options denoted as Hire Grant for Mr. Montecalvo vest in 25% increments on February 23rd of each year following the grant date. These option vesting schedules are consistent with the schedules for active employees as of February 2016. All other grants are subject to the vesting schedules set forth in footnotes 1 and 3 above.

(8)

The RSUs granted to Mr. Abraham will vest one-third on the anniversary of the grant provided that he remains employed by the Company, terminates with "good reason," is terminated without "cause" by the Company, dies or becomes disabled. The options awarded upon hire will vest in 25% increments on the anniversary of the grant.

2018 Option Exercises and Stock Vested Table

The following table provides information about the value realized by our NEOs on the exercise of stock options and vesting of stock awards and units during 2018. Mr. Birkett, Mr. Montecalvo and Mr. Abraham did not exercise any options or have any stock vest in 2018.

2018 Option Exercises and Stock Vested Table

	Option Awards				Stock Awards
Name	Number of Shares Acquired on Exercise (#)		Value Realized on Exercise ($)(1)		Number of Shares Acquired on Vesting (#)(2)		Value Realized on Vesting ($)(3)

William J. Federici		127,662		9,352,464		6,372		592,596

(1)

The value realized is equal to the difference between the option exercise price and the fair market value of our common stock on the date of exercise, multiplied by the number of options exercised.

(2)

This column includes PSUs that were awarded in 2015 and earned in 2017, and paid in 2018, whether or not either award was deferred under the Employee Deferred Compensation Plan and the partial vesting of Mr. Green's retention RSU award. For RSUs and PSUs, the total includes additional shares awarded pursuant to DEUs, which are credited on unvested PSUs over the three-year vesting period at a rate that assumes the participant will earn the target award. For PSUs, at the time of the payout, the credited DEUs are then increased or decreased based on the payout factor earned for the applicable three-year performance period. Because the payout factor earned for the 2015-17 performance period was 49.39%, the number of DEUs accrued over that period was multiplied by 49.39%. The following table shows the PSU payouts that vested, and the number of additional shares distributed due to DEUs.

(3)

The value of the PSUs was determined by multiplying the number of vested units by $102.51, the fair market value of our common stock on the payout date, February 19, 2019.

COMPENSATION TABLES

2018 Pension Benefits

Qualified Retirement Plan

Until December 31, 2006, we maintained a final average pay defined benefit pension plan, which calculated retirement benefits for all salaried participants as a percentage of average annual earnings. Effective January 1, 2007, each participant's accrued benefit under the Retirement Plan's pension formula was frozen, and the pension benefits related to service on or after January 1, 2007 for all existing and new participants are expressed as a "cash balance" type formula. Under the cash balance approach, an allocation is made at the end of each calendar year (or on employment termination, if earlier) to a participant's hypothetical cash balance account. The allocation is determined by the age of the participant and the percentage of annual compensation for that age band pursuant to the basic cash balance formula.

For participants who have attained minimum age and service requirements, an additional annual allocation is made to their accounts to replace all or part of the benefit for participants who were participating in the Retirement Plan on December 31, 2006 ("transition benefit"). The transition benefit percentage ceased on December 31, 2018. The transition benefit was applicable only to employees who were actively employed on December 31, 2006 and the allocation percentage was based on the age of the participant on that date. The transition benefit for Mr. Federici was 8.0%. All other continuing NEOs were not eligible to receive the transition benefit because they were not employed on December 31, 2006.

Each year, the balance in the hypothetical account will be credited with interest at a rate equal to the average 30-Year Treasury Bond Rate for November of the year prior to the year the interest is credited or 3.3%, if greater.

In general, the compensation used for determining a participant's benefits under the retirement plan consists of base salary, overtime, annual incentive awards (paid in cash or stock) and other cash remuneration, plus a participant's contributions to our 401(k) plan.

We froze pay and transition credits to the Retirement Plan as of December 31, 2018. Only interest credits will continue to accrue on previously accrued benefits for eligible participants on January 1, 2019 and beyond. No employees hired on or after January 1, 2017 are eligible for the Retirement Plan. In lieu of the Retirement Plan benefits, we have made enhancements to our 401(k) plan, including a non-elective contribution, which is currently 3% of a participant's compensation, subject to applicable Code limits.

Normal retirement age under the Retirement Plan is 65. Participants with ten years of service may retire and commence payment of their frozen benefits upon reaching age 55, with reduced benefits based on their age at the retirement date. A participant may begin distribution of his or her cash balance benefits on employment termination, without regard to age or years of service, but will forego future interest credits.

The benefit that each participant will receive at retirement will be the sum of the accrued benefit under the old pension formula as of December 31, 2006, plus the amount allocated to the participant's cash-balance account. A participant vests in his or her combined benefit upon completing three years of service.

Supplemental Executive Retirement Plan

2018 IRS requirements limit the compensation that can be used to calculate a participant's benefit under a qualified retirement plan to $275,000 and the annual benefit is limited to $220,000. The SERP benefits are substantially equal to the difference between the total benefit accrued under the Retirement Plan and the amount of benefit the Retirement Plan is permitted to provide under the statutory limits on benefits and earnings. The benefits are unfunded and paid out of our general assets. SERP benefits (other than interest credit accruals) froze in a similar manner to the freeze to the Retirement Plan in January 2019.

The SERP provides for benefits accrued on or after January 1, 2005 to be payable in a lump sum on the date that is six months following termination of employment. Benefits accrued before that date are payable at the same time and in the same form as under the Retirement Plan. SERP benefits may be reduced to reflect early commencement of benefits before age 65. The SERP was closed to new entrants effective January 1, 2017.

COMPENSATION TABLES

2018 Pension Benefits Table

The following table shows the present value of accumulated pension benefits that each U.S.-based NEO is eligible to receive under our Retirement Plan and the SERP. Mr. Birkett and Mr. Abraham are not eligible for and did not accrue benefits under the Retirement Plan or SERP.

(1)

Equals the number of full years of credited service as of December 31, 2018. Credited service generally begins with a participant's hire date and ends with the date of employment termination.

(2)

These present values assume that each NEO retires at age 65 for purposes of the Retirement Plan and the SERP. The assumed cash balance crediting rate is 3.30% in the Retirement Plan and the SERP. The discount rate and post-retirement mortality assumptions used in estimating the present values of each NEO's accumulated pension benefit vary by plan, as provided in the table below.

Plan	Rate	Post-retirement Mortality Assumption
Retirement Plan	4.30%	70% of the present value is calculated using a 50% male and 50% female blended RP-2014 annuitant mortality table without collar adjustment (removing MP-2015 improvement projections from 2006-2014) and applying Scale MP-2018 mortality improvements from 2006 on a generational basis, 30% of the present value is calculated using the RP-2014 gender specific annuitant mortality tables without collar adjustment (removing MP-2014 improvement projections from 2006-2014) and applying Scale MP-2018 mortality improvements from 2006 on a generational basis.
Plan	Rate	Post-retirement Mortality Assumption
SERP	3.55%	50% male and 50% female blended RP-2014 annuitant mortality table without collar adjustment (removing MP-2014 improvement projections from 2006-2014) and applying Scale BB 2-Dimensional mortality improvements from 2006 on a generational basis.

Actual benefit present values will vary from these estimates depending on many factors, including an executive's actual retirement age, future-credited years of service, form of payment election, applicable interest rates and regulatory changes.

COMPENSATION TABLES

2018 Nonqualified Deferred Compensation

The Employee Deferred Compensation Plan allows highly compensated employees to defer up to 100% of salary and cash bonus. Deferred cash contributions may be invested in a selection of investment options that mirror the funds available under our 401(k) plan.

With respect to employee contributions made before 2019, we matched them at the rate of 100% of the first 3% of salary deferrals, plus 50% of the next 2%, and employer matching contributions are 100% vested. Matching contributions ceased effective January 1, 2019. A non-elective contribution is also made on behalf of participants who exceed the applicable Code limits. Before 2019, participants were eligible to defer payout of annual bonus shares. We contributed one restricted incentive share for each four bonus shares deferred. PSUs remain eligible for deferral.

Incentive shares will vest on the fourth anniversary of the date of contribution or will vest pro rata on retirement, death or disability, if earlier. During the time these awards are deferred, they are deemed invested in our common stock and receive additional credits for DEUs. All deferred stock awards are distributed in shares of common stock.

Amounts deferred in any year, except for matching contributions on cash contributions, will be distributed automatically in a lump sum five years after the year of deferral. A participant may choose to defer these amounts to another date or until termination. Matching contributions are only distributed on termination. Participants may elect to receive distributions on termination in a cash or stock lump sum or up to ten annual installments.

Information regarding NEO's account balances in the Employee Deferred Compensation Plan is below. Mr. Birkett, Mr. Montecalvo and Mr. Abraham did not participate in this plan in 2018.

The total balance includes amounts contributed for prior years which have all been previously reported in the Summary Compensation Table for the year those amounts were deferred.

Payments on Disability

Each current NEO has long-term disability coverage, which is available to all eligible U.S. employees. The coverage provides full salary continuation for six months and thereafter up to 60% of pay with a $25,000 monthly limit. Eligible U.S. employees will earn cash balance pay credits until 2019. Employees who are vested in our Retirement Plan also receive continued medical coverage while on disability. Deferred compensation is payable according to the executive's election. Outstanding unvested stock options granted annually under our LTIP would be forfeited and outstanding vested stock options would be exercisable for the term of the option. Outstanding PSUs and unvested incentive shares would be forfeited when an employee becomes disabled. Lastly, the special retention stock, RSUs and options granted upon hire to Mr. Green, Mr. Birkett, Mr. Abraham and Mr. Montecalvo will vest upon disability.

COMPENSATION TABLES

Payments on Death

Each current U.S.-based NEO has group life insurance benefits that are available to all eligible U.S. employees. The benefit is equal to one times pay with a maximum limit of $500,000, plus any supplemental life insurance elected and paid for by the NEO. Deferred compensation is payable according to the executive's election on file. Outstanding unvested stock options granted annually under our LTIP, PSUs and incentive shares would be forfeited and outstanding vested stock options would become exercisable for the term of the option.

The special retention stock, RSUs and / or options granted to Mr. Green, Mr. Montecalvo, Mr. Birkett and Mr. Abraham upon hire will also vest upon death.

Estimated Payments Following Termination

We have an agreement with Mr. Green that entitles him to severance benefits on certain types of employment terminations not related to a CIC. All other NEOs are not covered by an employment agreement or a general severance plan and any severance benefits payable to them under similar circumstances would be determined by the Committee in its sole discretion.

Mr. Green

Mr. Green has an employment agreement that entitles him to continuation of his salary and welfare benefits at active employee rates for a period of 12 months, if he is terminated involuntarily other than for "Cause" or the Company gives notice to Mr. Green that it will not renew the term of his employment under the agreement. Mr. Green's employment agreement does not entitle him to severance payments or continued benefits if his employment is terminated for Cause or because of his death or disability (except as described above).

The restricted stock and stock options that Mr. Green received as an enticement award (but not any other restricted stock or stock options granted) will vest: (1) in the event of his termination other than for Cause, or (2) due to Good Reason.

"Cause" means any willful failure by Mr. Green to perform his duties or responsibilities or comply with any valid and legal directives of the Board; act of fraud; embezzlement; theft or misappropriation of the funds of the Company by Mr. Green; or Mr. Green's admission to or conviction of a felony or any crime involving moral turpitude, fraud, embezzlement, theft or misrepresentation; Mr. Green's engagement in dishonesty, illegal conduct or misconduct that is materially injurious to the Company; Mr. Green's breach of any material obligation of any written agreement with the Company; or a material violation of a rule, policy, regulation or guideline imposed by the Company or a regulatory body.

"Good Reason" means a material diminution in Mr. Green's base salary; a material reduction in Mr. Green's duties, authority or responsibilities; or the relocation of Mr. Green's principal place of employment in a manner that lengthens his one-way commuting distance by fifty (50) or more miles.

The obligation to pay severance pay is contingent on execution of a release and other customary provisions, including compliance with non-competition, non-solicitation and confidentiality obligations contained in the agreement.

Other NEOs

The RSUs that Mr. Montecalvo, Mr. Birkett and Mr. Abraham received as retention awards will vest: (1) in the event of termination other than for Cause or (2) due to Good Reason. The definitions of "Cause" and "Good Reason" are substantially the same as those that apply to Mr. Green.

COMPENSATION TABLES

Estimated Additional Severance Payments Table

The table below reflects amounts that eligible executives would receive on termination of employment for certain reasons, other than following a CIC. No NEO will receive any enhanced benefit because of a termination for cause. The amounts do not include amounts payable through a plan or arrangement that is generally applicable to all salaried employees, including equity acceleration values to the extent they apply to all LTIP participants.

Name	Event	Cash Severance		Continuation of Welfare Benefits(1)			Vesting of Unvested Equity			Total
Eric M. Green	Involuntary (no Cause) or Good Reason	$	885,000		$	16,080		$	12,001,883	$	12,902,963

(1)

This amount reflects the current premium incremental cost to us for continuation of elected benefits to the extent required under Mr. Green's agreement.

Payments on Termination in Connection with a Change-in-Control

We have entered into agreements with each of our U.S.-based NEOs, as well as certain other of our officers, which provide the benefits described below on qualifying terminations of employment in connection with or within two years following a CIC.

All currently employed NEOs except Mr. Green have CIC Agreements that are substantially similar and include the following:

•

Cash severance pay equal to two times the sum of the executive's highest annual base salary in effect during the year of termination and their target bonus immediately preceding the CIC.

•

Immediate vesting of any unvested benefits and matching contributions under our 401(k) plan and the Employee Deferred Compensation Plan as of the termination of the executive's employment.

•

Payment of short-term incentive compensation with respect to the period during which the termination occurs at target levels, prorated for number of days worked in the year.

•

Immediate vesting of all unvested stock options, stock appreciation rights ("SARs"), shares of stock, stock units and other equity-based awards at target levels.

•

Continued medical, dental, life and other benefits for 24 months after termination of the executive's employment, or until his or her retirement or eligibility for similar benefits with a new employer.

•

Payments will be reduced below the applicable threshold in the Code if the NEO would be in a better after-tax position than if the excise tax under Section 4999 of the Code applied. Based on assumptions described below, Mr. Green, and Ms. Flynn would have their payouts exceed the golden parachute threshold under the Code. However, only Ms. Flynn would have her payments cutback in that scenario because she would be in a better after-tax position than receiving the full amount.

•

Outplacement assistance up to $50,000.

The severance payments are payable in monthly installments and if the executive is a key employee at the time of his termination, payments will be delayed six months to the extent required by applicable tax law.

Employment terminations that entitle these executives to receive the severance benefits under a CIC consist of: (1) resignation following a constructive termination of his employment; or (2) employment termination other than due to death, disability, continuous willful misconduct or normal retirement. These terminations must occur within two years after a CIC.

2019 Annual Meeting and Proxy Statement   |   61

COMPENSATION TABLES

To receive the severance benefits under the agreement, an executive must agree not to be employed by any of our competitors or compete with us in any part of the United States for up to two years following employment termination for any reason and execute a release of claims in favor of the Company.

Mr. Green has a separate employment agreement, with change-in-control provisions that are substantially similar to the provisions contained in the other NEO agreements except for the following:

•

His payment is two times the sum of his annual base salary plus average of his bonus over the prior three years.

•

36-months of benefit continuation instead of 24 months.

•

Mr. Green's benefits may be reduced in the event he retires.

•

His agreement does not contain specific language regarding the satisfaction of performance goals for incentive compensation, or a payout of the short-term incentive compensation for the year of termination.

•

The definition of a CIC set forth below requires a change in two-thirds of our Board members rather than three-fourths.

•

The definition of "Cause" and "Constructive Termination," which is called "Good Reason," are slightly different and set forth in his employment agreement, which is described under Post-Employment Compensation Arrangements on page 47.

Definitions used in the CIC Agreements

The definitions below apply to all agreements, except as specifically noted above for Mr. Green above.

Definition of "Change-in-Control." For each agreement, a CIC includes any of the following:

•

Any person or entity other than us, any of our current directors or officers or a trustee or fiduciary holding our securities, becomes the beneficial owner of more than 50% of the combined voting power of our outstanding securities;

•

An acquisition, sale, merger or other transaction that results in a change in ownership of more than 50% of the combined voting power of our stock;

•

A change in the majority of our Board of Directors over a two-year period that is not approved by at least ²/3 of the directors then in office who were directors at the beginning of the period;

•

Any event requiring a reporting of a CIC pursuant to the regulations under SEC Form 8-K; or,

•

Execution of an agreement with us, which if consummated, would result in any of the above events.

Definition of "Cause." Cause generally includes:

•

Acts of dishonesty;

•

Repeated failure to perform duties which are demonstrably and deliberate and not remedied after receipt of notice;

•

Conviction of a felony; or,

•

Intentional breach of our COBC, which is materially and demonstrably injurious to the Company.

Definition of "Constructive Termination." A "Constructive Termination" generally includes any of the following actions taken by the Company without the executive's written consent following a CIC:

•

Significantly reducing or diminishing the nature or scope of the executive's authority or duties including reporting to someone whose scope of authority is diminished;

•

Materially reducing the executive's annual salary or incentive compensation opportunities;

•

Failure of a successor to assume the agreement;

•

Changing the executive's principal office location by more than 50 miles;

•

Failing to provide substantially similar fringe benefits, or substitute benefits that were substantially similar to the benefits provided as of the date of the agreement; or

•

Failing to obtain a satisfactory agreement from any successor to us to assume and agree to perform the obligations under the agreement.

COMPENSATION TABLES

Estimated Benefits on Termination Following a Change-in-Control

The following table shows potential payments to our NEOs if their employment terminates following a CIC under existing contracts, agreements, plans or arrangements. The amounts assume a December 31, 2018 termination date and use the closing price of our common stock as of that date, $98.03. Based on current assumptions, Mr. Montecalvo's benefit amount would be reduced $475,222 to put him in a better after-tax position than he would have been in had he received the full payout and paid the applicable golden parachute excise tax. All the values in the table are in U.S. Dollars. As Mr. Federici has terminated employment with the Company, and no payments could be made under his CIC agreement, he is not included in the table below.

Name	Aggregate Severance Pay(1)			PSU Acceleration(2)			Vesting of Restricted Stock RSUs(3)		Vesting of Stock Options(4)		Parachute Exercise Tax Impact(5)				Welfare Benefits Continuation(6)			Outplacement Assistance(7)			Total
Eric M. Green		$	3,171,095		$	3,701,221	$	1,312,984	$	6,987,703		—				$	50,899		$	50,000	$	15,273,902
Bernard J. Birkett		1,870,000			304,383		973,841		0			—				51,072			50,000		3,249,296
David A. Montecalvo		1,336,500			676,603		138,365		431,520			$	(475,222	)		50,619			50,000		2,208,385
Karen A. Flynn		1,683,000			977,653		0		1,383,858			—				50,852			50,000		4,145,363
Silji Abraham		1,353,000			228,312		456,597		124,030			—				750			50,000		2,212,689

(1)

For Mr. Green the aggregate severance pay amount represents two times the sum of the executive's (a) highest annual base salary in effect during his year of termination, and (b) the average of his bonus payout in the three years preceding the CIC (the "Severance Basis"). For Mr. Birkett, Mr. Abraham, Ms. Flynn, and Mr. Montecalvo, the bonus component of the Severance Basis is equal to their target bonus in the year of termination, and the aggregate severance pay is two times the Severance Basis.

(2)

This amount represents the payout of all outstanding PSU awards on a change-in-control at the target payout.

(3)

This amount represents the value of all unvested restricted awards, which would become vested on a change-in-control (whether or not the awards were deferred).

(4)

This amount is the intrinsic value, which is equal to the fair market value of a share of stock on December 31, 2018 minus the per-share exercise price of all unvested stock options for each executive multiplied by the number of unvested options as of December 31, 2018.

(5)

These amounts represent the impact of the modified cutback provisions in each executive's CIC Agreement, if applicable.

(6)

This amount represents the employer portion of the premiums for medical, dental and life insurance coverage for 24 months.

(7)

This amount estimates the cost of providing outplacement assistance.

CEO Pay Ratio

Applicable SEC rules require the disclosure of our median employee's pay and the ratio of that pay to our CEO's pay. Mr. Green's 2018 pay, as indicated in our 2018 Summary Compensation Table was $5,378,813 and our median employee's pay calculated in the same manner was $39,392. The ratio of Mr. Green's pay to our median worker's pay as determined under applicable SEC rules, therefore, is 137:1.

In determining our median employee, we used "base pay" as our compensation definition, which we then calculated as annual base pay based on a reasonable estimate of hours worked during 2018 for hourly workers, and upon salary levels for the remaining employees. We did not utilize cost-of-living adjustments. We annualized pay for those who commenced work during 2018. We used a valid statistical sampling methodology to identify the base pay for the median worker. In addition, in selecting the median worker, we used our global employment roster as of November 30, 2018, but excluded all employees in the following countries (with the number of employees excluded in parentheses): Australia (4), Argentina (6), Colombia (6), Italy (8), Spain (6), India (79), Israel (120), and Puerto Rico (178). As of November 30, 2018, total number of employees was 7,881, with U.S. employees totaling 3,421 and foreign employees totaling 4,460.

Our CEO pay ratio and the underlying compensation and employee count data are reasonable estimates calculated consistent with applicable SEC guidance governing use of estimates, adjustments, and statistical sampling permitted by the SEC.

PROPOSAL 2

Proposal 2 — Advisory Vote to Approve Named Executive Officer Compensation

At our 2018 Annual Meeting, our advisory vote on executive pay was approved by 96.6% of the votes cast. The Board of Directors and its Compensation Committee believed this to be a confirmation that our executive pay accurately and appropriately rewards performance. Previously, a majority of our shareholders approved holding an advisory vote on executive compensation annually. Therefore, we are seeking an advisory vote approving executive compensation this year.

As described more fully in the "Compensation Discussion and Analysis" section, our executive compensation program is designed to provide competitive executive pay opportunities tied to our short-term and long-term success and attract, motivate and retain the type of executive leadership that will help us achieve our strategic goals. The Compensation Committee continually reviews the compensation programs for our NEOs to ensure they achieve the desired goals of aligning our executive compensation structure with our shareholders' interests and current market practices.

This vote is advisory and not binding on the Company, the Board and the Compensation Committee. However, the Board and the Compensation Committee are interested in the opinions expressed by our shareholders on this proposal and will consider the outcome of the vote when making future compensation decisions for the NEOs. We encourage shareholders to review the Compensation Discussion and Analysis section of this Proxy Statement, for details regarding our executive compensation program.

Accordingly, the following resolution will be submitted for a shareholder vote at the 2019 Annual Meeting:

"RESOLVED, That the shareholders of West Pharmaceutical Services, Inc. (the 'Company') approve, on an advisory basis, the compensation of the Company's Named Executive Officers, as disclosed in this Proxy Statement pursuant to Item 402 of Securities and Exchange Commission Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative disclosures."

The Board unanimously recommends a vote FOR the approval, on an advisory basis, of the Company's
Named Executive Officer compensation, as stated in the above resolution.

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services

Our Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the Company's independent registered public accounting firm. As part of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm, subject to de minimis exceptions for non-audit services set forth in the applicable rules of the SEC. Prior to engagement for the next year's audit, Management will submit to the Audit Committee a list of services and related fees expected to be rendered by the independent registered public accounting firm during that year for pre-approval by the Committee. Those services must fall within one of the four following categories:

Audit Fees include fees for audit work performed on the financial statements and internal control over financial reporting, and work that generally only the independent registered public accounting firm can reasonably be expected to provide, including statutory audits or financial audits for our subsidiaries or affiliates; services associated with SEC registration statements; periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings (e.g., comfort letters, consents); and assistance in responding to SEC comment letters.

Audit-Related Fees are fees for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are traditionally performed by the independent registered public accounting firm, including due diligence related to potential business acquisitions/divestitures, financial statement audits of employee benefit plans and special procedures required to meet certain regulatory requirements.

Tax Fees include fees for all services, except those specifically related to the audit of the financial statements, which are performed by the independent registered public accounting firm's tax personnel and may include tax advice, tax analysis and compliance, and review of income and other tax returns.

All Other Fees are fees for those services not captured in any of the above three categories. The percentage of fees in this category that were approved by the Audit Committee under the de minimis exception was less than 1% of the total fees for 2018.

AUDIT COMMITTEE REPORT

Audit Committee Report

The Audit Committee reviewed the Company's financial-reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. PwC, the Company's independent registered public accounting firm for 2019, is responsible for expressing its opinion on the conformity of the Company's audited financial statements with generally accepted accounting principles and on the effectiveness of the Company's internal control over financial reporting.

The Audit Committee has reviewed and discussed with Management and PwC the audited financial statements for the year ended December 31, 2018, Management's assessment of the effectiveness of the Company's internal control over financial reporting and PwC's evaluation of the Company's internal control over financial reporting.

The Audit Committee has discussed with PwC the matters that are required to be discussed by Statement on Auditing Standards No. 61 (Communication With Audit Committees), as amended (AICPA, Professional Standards, Vol. I AU §380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T. PwC has provided to the Committee the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding PwC's communications with the Audit Committee concerning independence and the Committee has discussed with PwC that firm's independence from the Company.

The Audit Committee also considered whether the independent registered public accounting firm's provision of non-audit services to the Company is compatible with the auditor's independence. The Audit Committee has concluded that the independent registered public accounting firm is independent from the Company and its Management. Based on the considerations and discussions referred to above, the current members of the Audit Committee recommended to the Board that the audited financial statements for the year ended December 31, 2018 be included in the Company's 2018 Annual Report on Form 10-K.

PROPOSAL 3

Proposal 3 — Ratification of the Appointment of PricewaterhouseCoopers LLP as Our Independent Registered Public Accounting Firm for 2019

The Audit Committee is responsible for the appointment, compensation, retention, evaluation and oversight of the Company's independent registered public accounting firm. This Committee annually evaluates the independent registered public accounting firm's qualifications, performance and independence and assesses whether to continue to retain the firm or select a different firm.

As part of this review, the Audit Committee reviews PwC's capabilities and costs. Based on this review, the Audit Committee has determined that PwC has performed well, in a cost-effective manner, has a long-standing institutional memory, acts independently of Management, and provides critical input to the Audit Committee. Therefore, the Audit Committee has appointed PwC as our independent registered public accounting firm for 2019. Although shareholder approval for this appointment is not required, the Audit Committee and our Board are submitting the selection of PwC for ratification to obtain the views of shareholders and as a matter of good corporate governance. If the appointment is not ratified, the Audit Committee will reconsider whether or not to retain PwC. Representatives of PwC will be present at the 2019 Annual Meeting to answer questions and will have the opportunity to make a statement if they desire.

The Board unanimously recommends a vote FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2019.

You may revoke or change your vote any time before the proxy is exercised by filing with our Corporate Secretary a notice of revocation or a duly executed proxy bearing a later date. Attendance at the meeting will not by itself revoke a previously granted proxy.
