2020 Proxy Statement Summary

Advisory Resolution to Approve Executive Compensation (Proposal 2)

Consistent with the stockholders' advisory vote at our 2017 Annual Meeting of Stockholders, we determined to hold the advisory say-on-pay vote to approve our named executive officer ("NEO") compensation on an annual basis. Therefore, we are asking our stockholders to approve, on an advisory basis, our named executive officer compensation for fiscal year 2020. Our stockholders will have the opportunity to approve, on an advisory basis, our NEO compensation for fiscal year 2021 at the 2021 Annual Meeting of Stockholders.

The board of directors recommends a vote FOR this resolution because it believes that the policies and practices described in the "Compensation Discussion and Analysis" section beginning on page 37 of this proxy statement are effective in achieving the company's goals of linking pay to performance and levels of responsibility, encouraging our executive officers to remain focused on both short-term and long-term financial and strategic goals of the company, and aligning the interests of our executive officers with the interests of our stockholders by linking executive performance to stockholder value.

At our 2019 Annual Meeting of Stockholders, our stockholders approved the compensation of our fiscal year 2019 NEOs by a vote of approximately 94% in favor.

Ratification of the Appointment of Auditors (Proposal 3)

We are asking our stockholders to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2021. A summary of fees paid to

Fiscal Year 2020 Business Highlights

Deloitte & Touche LLP for services provided in fiscal years 2019 and 2020 is provided on page 83 of this proxy statement. The board of directors recommends a vote FOR this ratification.

Stockholder Proposal regarding Employee Representation on the Board of Directors (Proposal 4)

We have received notice from NorthStar Asset Management, Inc. Funded Pension Plan of its intention to present a resolution for action at the 2020 Annual Meeting, which calls for the board of directors to prepare a report to stockholders describing opportunities for the company to encourage the inclusion of non-management employee representation on the board.

The board believes that there exist already multiple means for any stockholder to recommend a prospective director candidate, including a company employee, for the board's consideration. Giving non-management employees a dedicated position on the board, a different process for board representation, or a different set of qualifications would undercut the role of the nominating/ corporate governance committee and the board in one of the most important and strategic elements of corporate governance. Our long-term business success is closely linked to our commitment to creating an environment in which our employees thrive. In line with this philosophy, our associates have numerous ways to be heard and exert influence outside of board representation. These reasons and others are set forth in greater detail beginning on page

86. The board of directors recommends a vote AGAINST this stockholder proposal.

Our Strategic Pillars. Our business strategy is based on three strategic pillars, which are designed to position us as the global market leader in human capital management ("HCM") technology and services:

Our Strategic Pillars

(HCM Solutions) (HRO Solutions) (Global Solutions)

• Grow a complete suite of cloud-based HCM solutions (HCM Solutions)
• Grow and scale our market-leading HR Outsourcing solutions (HRO Solutions)
• Leverage our global presence to offer clients HCM solutions wherever they do business (Global Solutions)

2020 Proxy Statement Summary

Despite the significant headwinds of the COVID-19 pandemic, fiscal year 2020 reflected continued progress at ADP:

Stockholder-Friendly Actions

• $2.5 billion in cash returned to stockholders via dividends ($1.5 billion) and share repurchases ($1 billion).





Transformation

We delivered sustainable long-term value across our strategic pillars by providing leading cloud-based software solutions to our clients and improving their experience through our ongoing service and transformation initiatives.

We executed on our workforce optimization program and a procurement initiative, which together yield approximately $150 million in annual run rate savings.

COVID-19 Response

• We rolled out a range of solutions to help our clients through the COVID-19 crisis and to prepare for the recovery.
• We implemented over 1,000 feature changes in response to 2,000 legislative updates in 60 countries.
• We achieved record Net Promoter Scores in June 2020 as a result of this elevated level of service delivered to our clients around the world.

Despite the impact of the COVID-19 pandemic, fiscal year 2020 results demonstrated continued progress on our transformation journey with solid top-line revenue growth balanced with margin expansion that together, drove earnings per share ("EPS") growth of 9%. While other key business drivers such as new business bookings and client retention were pressured by the pandemic, our overall results, together with our focus on sound capital allocation, have served to further strengthen our business model with high levels of recurring revenue, strong operating cash flow, and a solid balance sheet.

As a leading global provider of cloud-based HCM technology solutions to employers around the world, we have continued to process payroll and tax obligations and provide other HCM services to our clients, despite the unexpected challenges that our clients and their employees around

the world are facing. ADP's efforts have been focused on providing information and tools to help clients understand and navigate the governmental relief that has been adopted globally. As the global economy and landscape continues to evolve for our clients, whether due to legislative changes or other factors, ADP is committed to supporting our clients to help them navigate these challenges.

Our strategy continues to be the same -- to leverage the strength of our model to reinforce our competitive position by, first and foremost, reinvesting in the business. We believe that balancing investments in innovative solutions, client service tools, and distribution, is critical in helping to strengthen our market-leading offerings. We supplement

these investments through a disciplined approach to M&A. This focus on delivering top-line revenue growth, while also improving the efficiency and effectiveness of our operations, is complemented by a commitment to return excess cash to stockholders through dividends and disciplined share buybacks.

While the challenges presented by COVID-19 may affect the timing of our execution of parts of our strategy, we remain on a transformation journey, and our initiatives are yielding efficiencies and are focused on changing how we work. For fiscal year 2021, we remain focused on opportunities for innovation and growth while taking a deliberate balanced approach to managing expenses.

We are moving forward with a digital implementation and servicing initiative that leverages many of the capabilities we highlighted at our February 2020 Innovation Day. ADP also continues strategic investment in product and distribution to drive sustainable long-term growth.

Although COVID-19 is putting pressure on our financial performance, we believe this is transitory and the long- term prospects for ADP are in no way diminished. We will continue to monitor macro trends based on externally and internally available data and are using these indicators to drive real-time decisions as we remain committed to our long-term strategy, including the creation of long-term stockholder value by balancing top-line revenue growth with margin improvement to drive EPS growth.

2020 Proxy Statement Summary

Compensation Principles

We believe that compensation should be designed to create a direct link between performance and stockholder value. Five principles that guide our decisions involving executive compensation are that compensation should be:

1. based on (i) the overall performance of the company, (ii) the performance of each executive's business unit and (iii) each executive's individual performance
2. closely aligned with the short-term and long-term financial and strategic objectives that build sustainable long-term stockholder value
3. competitive, in order to attract and retain executives critical to our long-term success
4. consistent with high standards of corporate governance and best practices
5. designed to dampen the incentive for executives to take excessive risks or to behave in ways that are inconsistent with the company's strategic planning processes and high ethical standards

2020 Compensation Highlights

Consistent with our pay for performance philosophy, the compensation of our NEOs is structured with a significant portion of their total compensation at risk and paid based on the performance of the company and the applicable business unit. Our financial performance in fiscal year 2020 impacted the compensation for all of our executive officers,

not just our NEOs, in several ways, most notably through our annual cash bonus plan and performance-based stock unit ("PSU") program. Please refer to the "Compensation Discussion and Analysis" section on page 37 of this proxy statement, and the tables and narratives that follow

on page 58 of this proxy statement, for more details concerning the compensation of our NEOs.

Key highlights of our fiscal year 2020 executive compensation program

Base salary: For fiscal year 2020, we increased the base salary of each NEO as we determined the amount based on the executive's overall performance, level of responsibility, including expanded responsibility for certain NEOs, competitive compensation practices data and comparison to other company executives. To share in the sacrifice of the company's impacted employees as a result of the COVID-19 pandemic, all five NEOs took temporary base salary reductions.

bonus:for all the NEOs except for Mr. Weinstein whose target bonus percentage was increased from 80% to 100% to align closer to the market, effective in April 2020 and prorated (at 85%) accordingly for fiscal year 2020. Annual bonuses were based on the performance of the company and the business units as well as the strategic progress realized for fiscal year 2020 against the NEOs' bonus objectives. For fiscal year 2020, our NEOs received cash bonuses that averaged approximately 48.6% of target.

Equity awards: As part of our equity compensation program in fiscal year 2020, consistent with fiscal year 2019, we granted our executive officers PSUs and stock options.

2020 Proxy Statement Summary

2020 Incentive Compensation Performance Metrics

Our financial performance impacted the compensation of our executive officers in several ways, most notably our annual cash bonus plan and performance-based stock unit ("PSU") program.

The compensation committee's determination of incentive compensation under our annual cash bonus plan for our executive officers, including our NEOs, was based on fiscal year 2020 revenue growth, new business bookings growth, adjusted EBIT growth and strategic objectives.

Performance for all metrics, including the strategic objectives, are formulaically measured, based on predetermined, objectively quantifiable goals. Targets and results exclude the impact of certain items pursuant to predetermined categories of adjustments established by the compensation committee at the time that targets were set. However, no discretionary adjustments were made outside of these predetermined categories in favor of management to reduce the negative impact of the COVID-19 pandemic.

Details with regard to the strategic objectives are provided on page 50 and the financial goals and performance results are summarized below.

Annual Cash Bonus

Revenue Growth	6.2%	3.7%, excluding the impact of foreign currency fluctuations in excess

New Business Bookings Growth(1)	7.8%	-18.5%
Adjusted EBIT Growth(2)	11.6%	5.7%, excluding the impact of foreign currency fluctuations in excess

1. For fiscal year 2020, our new business bookings definition includes annualized recurring revenues anticipated from sales orders to new and existing clients for Employer Services and Professional Employer Organization ("PEO") Services. It excludes revenue that is one-time in nature and zero-margin PEO pass-through revenues.
2. Our adjusted EBIT measure excludes the impact of taxes, certain interest expense, certain interest income, and certain other items. We continue to include the interest income earned on investments associated with our client funds extended investment strategy and interest expense on borrowings related to our client funds extended investment strategy as we believe these amounts to be fundamental to the underlying operations of our business model. Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2020 and 2019.

2020 Proxy Statement Summary

We firmly believe that creating sustainable long-term value for stockholders is enabled through such strong governance practices and open dialogue with stockholders through continuous direct engagement.

Our fiscal year 2020 corporate governance actions and enhancements included:

• A rotation of membership among our committees and appointment of new chairs to our corporate development and technology advisory committee and nominating/corporate governance committee (November 2019)

• The issuance of our second Corporate Social Responsibility report detailing ESG matters, including information security, privacy and diversity (November 2019)

• Ongoing board refreshment with the appointment of a new board member with leadership and strategic expertise in technology-driven solutions, digital transformation and cybersecurity that will prove invaluable to ADP's vision for our HCM technology portfolio (April 2020)

In fiscal year 2021 to date, ongoing corporate governance actions and enhancements include:

• The reduction of the percentage of the voting power of the company's outstanding shares of common stock required to call a special meeting of stockholders from 33% to the more common standard of 25% (August 2020)

Fiscal Year 2020 Stockholder Engagement

• Invited stockholders representing nearly half of our shares outstanding to discuss our strategy, corporate governance and executive compensation programs, and held meetings with stockholders representing over 40% of our shares outstanding

Our Stockholder and Stakeholder

Engagement Process

We value stockholder engagement and feedback as we strive to deliver strong financial performance and sustained value creation for our investors. Our ongoing investor engagement program includes outreach focused on the company's strategy, corporate governance and executive compensation programs. In addition to management, many of these engagements include participation by certain members of our board of directors, including our chairman. Director participation continues to be part of our engagement in fiscal year 2021.

• The nomination of a new director nominee with an extensive background in technology integration, cybersecurity, risk management, strategic planning and large complex system development, delivery and deployment (September 2020)
• Over 100 meetings held with top-50 stockholders to discuss business performance and seek overall feedback

What we learn through our ongoing engagements is regularly shared with our board of directors and incorporated into our disclosures, plans and practices, as appropriate. For example, over the past year, observations were made by some of our investors regarding our special meeting rights threshold for stockholders. In response, we reduced our percentage threshold in August 2020 to 25%, which is the most common threshold among U.S. S&P 500 companies with special meeting rights for shareholders. In addition, based on feedback from our investors, we continue to enhance our cybersecurity and privacy disclosures in our proxy to give our stockholders better insight into how our board thinks about and approaches these matters.

Questions and Answers About the Annual Meeting and Voting

HOW MANY VOTES ARE NEEDED TO APPROVE THE PROPOSALS, AND WHAT IS THE EFFECT OF BROKER NON-VOTES

OR ABSTENTIONS?

Proposal 1:

The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to elect a director, provided that if the number of nominees exceeds the number of directors to be elected (a situation that the company does not anticipate), the directors shall be elected by the vote of a plurality of the shares represented in person or by proxy. Votes may be cast in favor of or against each nominee, or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote, provided that if the number of nominees exceeds the number of directors to be elected, abstentions will be excluded entirely and will have no effect on the vote. A broker non-vote will have no effect on the outcome of this proposal because the non-votes are not considered in determining the number of votes necessary for approval.

Proposal 2:

The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to approve the advisory resolution on executive compensation. Votes may be cast in favor of or against this proposal or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. A broker non-vote will have no effect on the outcome of the advisory resolution because the non-votes are not considered in determining the number of votes necessary for approval. Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any named executive officer and will not be binding on or overrule any decisions by the compensation committee or the board of directors.

Because we value our stockholders' views, however, the compensation committee and the board of directors will consider carefully the results of this advisory vote when formulating future executive compensation policy.

Proposal 3:

The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to ratify the appointment of Deloitte & Touche LLP as the company's independent registered public accounting firm for fiscal year 2021. Votes may be cast in favor of or against this proposal or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. Brokers have the authority to vote shares for which their customers did not provide voting instructions on the ratification of the appointment of Deloitte & Touche LLP.

Proposal 4:

The stockholder proposal submitted by NorthStar Asset Management, Inc. Funded Pension Plan to call for the board of directors to prepare a report to stockholders describing opportunities for the company to encourage the inclusion of non-management employee representation on the board, if properly introduced at the 2020 Annual Meeting, requires the affirmative vote of a majority of the shares represented in person or by proxy and entitled to vote thereon. Votes may be cast in favor of or against this proposal or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. If your broker holds your shares, your broker is not entitled to vote your shares on this proposal without your instruction. Broker non-votes will have no effect on the outcome of this proposal because the non-votes are not considered in determining the number of votes necessary for approval.

Questions and Answers About the Annual Meeting and Voting

WHAT IS "HOUSEHOLDING?"

To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding our stock but share the same address, we have adopted a procedure known as "householding." Under this procedure, certain stockholders of record who have the same address and last name, and who do not participate in electronic delivery of proxy materials, will receive only one copy of our Notice of Internet Availability of Proxy Materials and, as applicable, any additional proxy materials that are delivered until such time as one or more of these stockholders notifies us that they want to receive separate copies. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If you are a registered stockholder and choose to have separate copies of our Notice of Internet Availability of Proxy Materials, proxy statement and annual report on Form 10-K mailed to you, you must "opt-out" by writing to Broadridge Financial Solutions, Inc., Householding Department, 51 Mercedes Way, Edgewood, New York, 11717 or by calling 1-866-540-7095 and we will cease householding all such disclosure documents within

30 days. If we do not receive instructions to remove your accounts from this service, your accounts will continue to be "householded" until we notify you otherwise. If you own our common stock in nominee name (such as through a broker), information regarding householding of disclosure documents should have been forwarded to you by your broker.

You can also contact Broadridge Financial Solutions, Inc. at 1-866-540-7095 if you received multiple copies of the Annual Meeting materials and would prefer to receive a single copy in the future.

Corporate Governance

The board of directors' categorical standards of director independence are consistent with NASDAQ listing standards and are available in the company's corporate governance principles on our corporate website at www.adp.com.

To access these documents, click on "Investors," then "Corporate Governance," and then "Governance Documents." The board of directors has determined that Mses. Haynesworth, Katsoudas, Keene and Wijnberg and Messrs. Bisson, Clark, Jones, Lynch, Powers and Ready meet these standards and are independent for purposes of the NASDAQ listing standards. All current members of the audit, compensation, nominating/corporate governance, and corporate development and technology advisory committees are independent.

In the ordinary course of business, the company has business relationships with certain companies in which ADP directors also serve as executive officers or on the board of directors, including for example, hardware, software, HCM and other technology services. Based on the standards described above, the board of directors has determined that none of these transactions or relationships, nor the associated amounts paid to the parties, was material or would impede the exercise of independent judgment.

It is our policy that our directors attend the Annual Meetings of Stockholders.

All of our directors then in office attended our 2019 Annual Meeting of Stockholders. During fiscal year 2020, our board of directors held six (6) meetings. All of our incumbent directors attended at least 75%, in the aggregate, of the meetings of the board of directors and the committees of which they were members during the periods that they served on our board of directors during fiscal year 2020.

Executive sessions of the non-management directors are held during each meeting of the committees and the board of directors. Mr. Jones, our independent non-executive chairman of the board, presided at each executive session of the board of directors.

Board Leadership Structure

Our corporate governance principles do not require the separation of the roles of chairman of the board and chief executive officer because the board believes that effective board leadership can depend on the skills and experience of, and personal interaction between, people in leadership roles. Our board of directors is currently led by Mr. Jones, our independent non-executive chairman of the board. Mr. Rodriguez, our chief executive officer, serves as a member of the board of directors. The board of directors

believes this leadership structure is in the best interests of the company's stockholders at this time. Separating these positions allows our chief executive officer to focus on developing and implementing the company's business plans and supervising the company's day-to-day business operations, and allows our chairman of the board to lead the board of directors in its oversight, advisory, and risk management roles.

Board Composition and Director Succession Planning

The board takes a thoughtful approach to its composition to ensure alignment with the company's evolving corporate strategy. We believe our board composition strikes a balanced approach to director tenure and allows the board to benefit from a mix of newer directors who bring fresh

perspectives and seasoned directors who bring continuity and a deep understanding of our complex business. We refresh our board and assess our board succession plans regularly with this balance of tenure and experience in mind. Seven of our director nominees have a tenure of five

Our director succession planning is conducted in the context of a skillset review designed to focus on key areas of skills and experience deemed to be most helpful to driving board performance. Our nominating/corporate governance committee evaluates these desired attributes on an ongoing basis and adds new skills and qualifications as necessary in light of the company's changing strategy and needs.

Individual director evaluations are also conducted by the nominating/corporate governance committee on an annual basis, in close coordination with our chairman.

The form of assessment used to facilitate this review is refreshed each year to ensure relevance and covers a broad array of topics relevant to individual performance such as knowledge, expertise, commitment, preparation, integrity and judgment. This process facilitates director succession planning as it helps identify opportunities to enhance individual performance and any relevant feedback is communicated to the individual director.

In addition to individual evaluations, the nominating/corporate governance committee, working with our chairman, conducts a thorough evaluation at the board and committee levels to ensure the effectiveness of the directors and their ability to work as a team in the long-term interest of the company. This assessment is conducted through a questionnaire process, which is also refreshed each year, and designed to elicit feedback with respect to areas such as board/committee structure, governance, communication, culture, risk and strategy. Responses are shared and discussed with the nominating/corporate governance committee. The committee then shares the output of this process with the full board along with a series of recommendations that are subsequently implemented to improve board and committee performance, practices and procedures.

The company also has a director retirement policy in place to promote thoughtful board refreshment, as set forth in further detail under "Retirement Policy" on page 19 of this proxy statement.

Director Nomination Process

Our nominating process ensures our board consists of a well-qualified and diverse group of leaders who bring an important mix of boardroom and operating experience.

When the board of directors decides to recruit a new member, or when the board of directors considers any director candidates submitted for consideration by our stockholders, it seeks strong candidates who, ideally, meet all of its categorical standards of director independence, and who complement our identified board skillset needs. Additionally, candidates should possess the following personal characteristics: (i) business community respect for his or her integrity, ethics, principles, insights and analytical ability; and (ii) ability and initiative to frame

insightful questions, speak out and challenge questionable assumptions and disagree without being disagreeable. The nominating/corporate governance committee

will not consider candidates who lack the foregoing personal characteristics.

In addition, the nominating/corporate governance committee considers a wide range of other factors in determining the composition of our board of directors, including diversity of thought and background, as well as individual qualities such as professional experience, skills, education and training. Our nominating/corporate governance committee also considers a range of types of diversity, including race, gender, ethnicity, age, culture

Automatic Data Processing, Inc. - Proxy Statement  | 18

Corporate Governance

and geography. The nominating/corporate governance committee retains a third-party search firm from time to time to identify and evaluate, as appropriate, potential nominees to the board. Nominations of candidates for our board of directors by our stockholders for consideration

at our 2021 Annual Meeting of Stockholders are subject to the deadlines and other requirements described under "Stockholder Proposals" on page 88 of this proxy statement.

Retirement Policy

Our director retirement policy provides that, subject to such exceptions on a case by case basis as the board of directors shall determine, no person will be nominated by the board of directors to serve as a director following the date he or she turns 72. Management directors who are no longer officers of the company are required to offer to resign from the board of directors.

After considering his many contributions, including the number of board objectives for which he provided great insight and value, as well as his knowledge and expertise, and relatively short tenure on the board, the board of directors previously waived the mandatory retirement age of 72 for Mr. Clark. The waiver was effective upon his 72nd birthday in calendar year 2018 and allows Mr. Clark to stand for re-election until after his 75th birthday.

Committees of the Board of Directors

During fiscal year 2020, our board of directors held six (6) meetings. The table below provides the current membership and meeting information for each of the committees of the board of directors.

The Board's Role in Risk Oversight

Our board of directors provides oversight with respect to the company's enterprise risk assessment and risk management activities, which are designed to identify, prioritize, assess, monitor and mitigate the various risks confronting the company, including risks that are related to the achievement of the company's operational and financial strategy. As set forth in more detail below, the board of directors performs this oversight function periodically as part of its meetings and also through its audit, compensation and nominating/corporate governance committees, each of which examines various components of risk as part of its assigned responsibilities. In addition,

our corporate development and technology advisory committee advises the board with respect to certain risks assigned to oversight of the full board, principally around technology and innovation, strategic investments, acquisitions and divestitures.

Our committees report back on risk oversight matters directly to the board of directors on a regular basis. Management is responsible for implementing and supervising day-to-day risk management processes and reporting to the board of directors and its committees as necessary.

Corporate Governance

Audit Committee

Our audit committee focuses on financial risks, including reviewing with management, our internal auditors, and our independent auditors, the company's major financial risk exposures, the adequacy and effectiveness of accounting and financial controls, and the steps management has taken to monitor and control financial risk exposures.

Oversight of Cybersecurity

In addition, our audit committee reviews risks related to compliance with applicable laws, regulations, and ethical standards, and also operational risks related to information security and system disruption. Our audit committee regularly receives, reviews and discusses with management presentations and analyses on various risks confronting the company.

Our board of directors recognizes that security is integral to our products, our business processes and infrastructure. The mission of our global security organization ("GSO") is to protect client data and funds and prevent security incidents. Our GSO is tasked with monitoring physical and cybersecurity risks, including operational risks related to information security and system disruption. A cross-functional,enterprise-wide management program operates to ensure our global security program's effectiveness and members of the company's executive committee, through an executive security council, routinely review strategy, policy, program effectiveness, standards enforcement and cyber issue management. Our board of directors and our audit committee are actively engaged in the oversight of our global information security program. More information on our program is available on our corporate website, at www.adp.com. To access this information, click on "About ADP," then "Data Security."

• Our audit committee receives regular, quarterly reports on these matters from our chief security officer, including on the status of projects to strengthen the company's security systems and improve cyber readiness, as well as on existing and emerging threat landscapes. Concurrent and in addition to these reports, our chief legal and compliance officer provides a legal, regulatory and ethics update at each meeting of the audit committee, which includes matters of cybersecurity.

• Given the importance of information security to our stakeholders, our board also receives an annual report from our chief security officer to review our program for managing these security risks.

• Our global information security program is subject to an annual third-party assessment overseen by our board
  of directors.

• Members of our board also observe an annual cybersecurity table-top exercise conducted by senior management to validate, test and assess the effectiveness and adequacy of certain roles and decision-making processes in the event of an incident.

Oversight of Privacy

Intertwined with our global information security program is our global privacy program. Our audit committee oversees matters of privacy, and receives reports on these matters at each meeting from our chief legal and compliance officer, as well as regular updates from our head of compliance, including on related risk assessment and risk management activities. On a management level, ADP's privacy program is led by ADP's global chief privacy officer and the members of the global data privacy and governance team, in cooperation with the privacy stewards of all of ADP's business units and functional areas. Our global chief privacy officer provides regular reports to our company's executive committee, and our audit committee is actively engaged in the oversight of our global privacy program.

• ADP's Privacy Commitment: We are committed to compliance with privacy requirements and the protection of all personal data processed by ADP. ADP has adopted a set of privacy principles that serve as the foundation for our global privacy program, which includes our global privacy policy and our binding corporate rules (BCRs), all of which may be found in greater detail on our corporate website, at www.adp.com. To access this information, click on "About ADP," then "Data Privacy."
• Our BCRs cover the transfer of data between ADP affiliates across the globe and ensure the highest standard of protection to personal data processed by ADP, regardless of where such data is being processed. Our BCRs establish the rules for processing personal data at ADP as both a data processor (covering the processing of clients' data of the European Union) and a data controller (covering the data of our employees under a controller workplace code, and other business associates under a business controller code regardless of where such data is being collected). We continue to rank among an elite number of companies worldwide to have gained regulators' approval to implement BCRs as both a data processor and data controller.

Compensation Committee

Our compensation committee oversees risks related to compensation policies and practices, including management succession planning and our talent strategy, including the recruitment, development and retention of executive talent.

Compensation and Risk Management

Our compensation committee considered the risks presented by the company's compensation policies and practices at its meetings in August 2019 and 2020 and believes that our policies and practices of compensating employees do not encourage excessive or unnecessary risk-taking for the following reasons:

• Diverse Performance Measures. Our incentive plans have diverse performance measures, including company and business unit financial measures, key strategic objectives, and individual goals.

• Balance. Our compensation programs balance annual and long-term incentive opportunities, cash and equity, and fixed and variable incentives.

• Payout Caps. We cap incentive plan payouts within a reasonable range.

• Mix. The mix of performance- based equity awards and stock options in our long-term incentive programs serves the best interests of stockholders and the company.

• Stock Ownership Guidelines. Our stock ownership guidelines link the interests of our executive officers to those of our stockholders.

• Clawback Policy. Our clawback policy allows for the recovery of both cash and equity incentive compensation from any current or former executive who engages in any activity that is in conflict with or adverse to the company's interests, including fraud or conduct contributing to any financial restatements or irregularities.

• Other. We prohibit our directors and all of our employees from engaging in any hedging or similar transactions involving ADP securities, holding ADP securities in a margin account, or pledging ADP securities as collateral for a loan. Any transactions in ADP securities by our executive officers are executed through a 10b5-1 program.

Nominating/Corporate Governance Committee

Our nominating/corporate governance committee oversees risks associated with board structure and other corporate governance policies and practices, including matters of corporate citizenship and the review and approval of any related- person transactions under our Related Persons Transaction Policy.

The Board's Role in Strategy Oversight

Our directors take an active role in the oversight of the company's strategy at both a board and committee level, with management responsible for the execution of our business strategy. In addition to regular performance updates to the board and committees, the company

convenes a dedicated strategy session each year with the board. This ongoing effort enables the board to focus on company performance over the short, medium and long- term horizons, as well as the quality of operations and industry trends.

The Board's Role in Human Capital Management and Talent Development

As part of its focus on human capital management and tight integration with company strategy, a key responsibility of our board of directors is to ensure that ADP has a strong, performance-driven senior management team in place. In connection with this responsibility, our board of directors oversees the development and retention of senior talent to ensure that an appropriate succession plan is in place for our CEO as well as the members of the company's executive committee that directly support our CEO.

Our compensation committee regularly reviews the bench strength of our senior management talent, including readiness to take on additional leadership roles and developmental opportunities needed to prepare senior leaders for greater responsibilities.

As part of building a diverse and inclusive workforce to support a culture of openness and innovation at ADP, our compensation committee also regularly assesses the talent pool of candidates just below the executive committee level to ensure a robust and diverse talent pipeline. In parallel,

Automatic Data Processing, Inc. - Proxy Statement  | 26

the company shares with other committees of the board, as appropriate, a similar view of the talent pipeline of various functions and businesses within the company. For example, the company annually shares with CDTAC our talent acquisition strategy, evolving skill mix, composition and talent pipeline of the company's global product and technology organization.

While our compensation committee has the primary responsibility to develop succession plans for the CEO position, it regularly reports to the board of directors and decisions are made at the board level. In connection with this responsibility for developing managerial succession plans, our board of directors reviews, at least annually, the short, medium and long-term succession plans for the company's senior management, including the CEO. In addition, our board meets regularly with high-potential executives from ADP's various business units at each in-person board meeting, which provides our board with greater, direct exposure to a broader group of pipeline candidates.

Corporate Governance

Corporate Social Responsibility and Sustainability Governance

ADP is committed to delivering more human, simple and sustainable business solutions for all of those we serve. We believe that our vision for corporate social responsibility ("CSR") will attract, engage and retain top talent, bolster continued business performance and conserve environmental resources for our company and our clients. We have pledged to help build a better workforce - for our company, our associates, our clients and our world. This commitment is reflected in our 2019 CSR report.

Our commitment to CSR is a core principle within ADP's mission, vision and values, and encompasses everything

from corporate governance, ethics and environmental stewardship to diversity, philanthropy and promoting employee growth and belonging around the world. We strive to embody an inclusive culture that extends beyond our diversity and inclusion function and believe that leadership drives performance and innovation through employee growth, belonging and greater purpose. We believe sustainability is about creating value for all of our stakeholders: our people, our clients, our partners, our investors and our community at large. We continue to deepen our sustainability efforts in four key pillars:

Innovation	Associates	Community	Environment

At ADP, we design for people. By working at the forefront of our clients' needs, we anticipate trends and create solutions together. Our innovation strategy is simple: We innovate by anticipating the future of work, the future of HCM and the future

of pay in order to meet the evolving and unique needs of our clients and their workers.

Our long-term business success is closely linked to our commitment to creating an environment in which our associates thrive. We believe in a competitive, inclusive and diverse workforce that represents the communities we serve. This is vital in building a company where our employees feel valued, welcome, and can achieve their full potential.

Responsibility to the world around us is at the heart of our business. We believe that our company is only as strong as the communities in which we operate. By elevating our communities, we support critical causes and provide a foundation for our business to continue thriving.

Environmental sustainability is integral to both our CSR program and our business strategy. We understand which environmental issues are relevant to our business and offer opportunities for us to make a meaningful impact. We also believe that creating sustainable products and streamlining our operations drives efficiency, innovation and, ultimately, long-termvalue-creation.

Our board of directors is squarely focused on the sustainability of our business for the long-term. In line with this focus, the nominating/corporate governance committee oversees the company's policies and programs on issues of corporate citizenship, including our CSR and sustainability program, as well as ADP's philanthropic activities. The committee receives periodic reports and updates from

the company's chief diversity and inclusion & CSR officer

("CSRO") and reports back on these matters to the full board. Our board members have complete and open access to senior members of management, including our CSRO. ADP's CSR activities are coordinated by our CSRO, who reports to ADP's chief human resources officer.

We invite you to visit sustainability.adp.com to read more about our CSR and sustainability efforts.

ADP Boulevard, Roseland, New Jersey 07068, leaving a message for a return call at 973-974-5770 or sending an email to [e-mail]. We will relay any such communication to the non-management director to

which such communication is addressed, if applicable, or to the most appropriate committee chairperson, the chairman of the board, or the full board of directors, unless, in any case, it is outside the scope of matters considered by the board of directors or duplicative of other communications previously forwarded to the board of directors.

Communications to the board of directors, the non- management directors, or to any individual director that relate to the company's accounting, internal accounting controls, or auditing matters are referred to the chairperson of the audit committee.

Transactions with Related Persons

We have a written "Related Persons Transaction Policy" pursuant to which any transaction between the company and a "related person" in which such related person has a direct or indirect material interest, and where the amount involved exceeds $120,000, must be submitted to our nominating/corporate governance committee for review, approval, or ratification.

A "related person" means a director, executive officer or beneficial holder of more than 5% of the company's outstanding common stock, or any immediate family member of the foregoing, as well as any entity at which any such person is employed, is a partner or principal (or holds a similar position), or is a beneficial owner of a 10% or greater direct or indirect equity interest in that entity. Our directors and executive officers must inform our general counsel at the earliest practicable time of any

plan to engage in a potential related person transaction. This policy requires our nominating/corporate governance committee to be provided with full information concerning the proposed transaction, including the benefits to the company and the related person, any alternative means by which to obtain like benefits, and terms that would prevail in a similar transaction with an unaffiliated third party. In considering whether to approve any such transaction, the nominating/corporate governance committee will consider all relevant factors, including the nature of the interest

of the related person in the transaction and whether the transaction may involve a conflict of interest.

Specific types of transactions are excluded from the policy, such as, for example, transactions in which the related person's interest derives solely from his or her service as a director of another entity that is a party to the transaction.

Compensation Committee Interlocks and Insider Participation

Ms. Katsoudas and Messrs. Clark, Hubbard and Lynch are the four independent directors who currently sit on the compensation committee. No compensation committee member has ever been an officer of the company. During fiscal year 2020 and as of the date of this proxy statement, no compensation committee member has been an employee of the company or eligible to participate in our employee compensation programs or plans, other than the

company's amended and restated 2008 Omnibus Award Plan under which non-employee directors previously have received stock option grants and deferred stock units ("DSUs") or, in the case of our 2018 Omnibus Award Plan, DSUs. None of our executive officers have served on the compensation committee or on the board of directors

of any entity that employed any of the compensation committee members or directors of the company.

Automatic Data Processing, Inc. - Proxy Statement  | 28

Compensation of Non-Employee Directors

Our nominating/corporate governance committee reviews and evaluates non-employee director compensation

on an annual basis to ensure that our directors are compensated appropriately for their time commitment and responsibilities. The nominating/corporate governance

committee makes recommendations to the board of directors, as appropriate, based on its review, benchmark information from peer companies, and other relevant data. The elements of our non-employee director compensation program are as follows:

Compensation Element		Fiscal Year 2020 Compensation
Director Annual Retainer	•	$195,000 Deferred Stock Units ("DSUs")
	•	$115,000 Cash or DSUs
Additional Non-Executive Chairman Retainer	•	$100,000 DSUs
	•	$100,000 Cash or DSUs
Committee Chair Retainers (Cash, Deferred or DSUs)	•	Audit: $20,000
	•	Compensation: $15,000
	•	Nominating/Corporate Governance: $15,000
	•	Corporate Development and Technology Advisory:

Meeting Fees (Cash, Deferred or DSUs)	Board Meetings:
	•	$2,000, per meeting, beginning with the eighth meeting
	Committee Meetings:
	•	$1,500 per meeting, beginning with the eighth meeting

Annual Retainers

The annual retainer for non-employee directors is $310,000, $195,000 of which is paid in the form of DSUs and $115,000 of which may, at the election of each director, be paid in cash or in DSUs.

In addition, the chairman of our board of directors receives an incremental retainer of $200,000, $100,000 of which is paid in the form of DSUs and $100,000 of which may, at the election of the chairman, be paid in cash or in DSUs. This incremental retainer resulted in a total annual retainer of $510,000 for the chairman of our board of directors in fiscal year 2020.

The chair of the audit committee was paid an additional annual retainer of $20,000, and each chair of the compensation, nominating/corporate governance, and corporate development and technology advisory committees was paid an additional annual retainer of

$15,000. The additional annual retainer may, at the election of each committee chair, be paid in cash, deferred or paid in DSUs.

Meeting Fees

Meeting fees are not paid in respect of the first seven meetings of the board of directors or of any individual committee. Non-employee directors receive $2,000 for each board of directors meeting attended and $1,500 for each committee meeting attended beginning with the eighth meeting of the board of directors or any individual committee, as applicable. Meeting fees may, at the election of each director, be paid in cash, deferred, or paid in DSUs. Under our current 2018 Omnibus Award Plan ("2018 Omnibus Award Plan") and prior amended and restated 2008 Omnibus Award Plan (the "Prior Plan"), a director may specify whether, upon separation from the board, he or she would like to receive any deferred cash amounts in a lump-sum payment or in a series of substantially equal annual payments over a period ranging from two to ten years. For fiscal year 2020, meeting fees were paid in cash to the audit committee members who participated in eight meetings.

29  | Automatic Data Processing, Inc. - Proxy Statement

Compensation of Non-Employee Directors

Deferral Policy

Pursuant to our 2018 Omnibus Award Plan (and previously, under our Prior Plan), each non-employee director is credited with an annual grant of DSUs on the date established by the board for the payment of the annual retainer equal in number to the quotient of the non- elective portion of the retainer ($195,000 for fiscal year 2020 and $295,000 in the case of the chairman), divided by the closing price of a share of our common stock on the date this amount is credited. The elective portion of the annual retainer is credited in the same manner for directors who elect DSUs. DSUs are fully vested when credited to a director's account. When a dividend is paid on our common stock, each director's account is credited with an amount equal to the cash dividend. When a director ceases to serve on our board, such director will receive a number of shares of common stock equal to the number of DSUs in such director's account and a cash payment equal to the dividend payments accrued, plus interest on the dividend equivalents from the date such dividend equivalents were credited. The interest will be paid with respect to each twelve-month period beginning on November 1 of such period to the date of payment and will be equal to the rate for five-year U.S. Treasury Notes published in The Wall Street Journal® on the first business day of November of each such twelve-month period plus 0.50%. Non-employee directors do not have any voting rights with respect to their DSUs. All of our non-employee directors chose to receive the entire elective portion of their annual retainers in the form of DSUs during fiscal year 2020.

Role of the Nominating/Corporate

Governance Committee

The nominating/corporate governance committee is responsible for reviewing, evaluating, and making recommendations to the board on an annual basis with respect to all aspects of non-employee director compensation. The full board then reviews these recommendations and makes a final determination on the compensation of our non-employee directors. During fiscal year 2020, the nominating/corporate governance committee engaged FW Cook, compensation consultant to the compensation committee, to review the design and competitiveness of our non-employee director compensation program.

In connection with this annual review, there were no changes made to the non-employee director compensation program for fiscal year 2021.

Stock Ownership Guidelines

Our stock ownership guidelines are intended to promote ownership in the company's stock by our non-employee directors and to align their financial interests more closely with those of other stockholders of the company. Each non-employee director has a minimum stockholding requirement of our common stock equal to five times his or her annual cash retainer.

For Mr. Gregoire and Ms. Gooden, this amount reflects a donation made by the ADP Foundation to a charitable organization of their choice in connection with their years of service and contributions as directors of the company. For the other directors, this amount reflects contributions by the ADP Foundation that match the charitable gifts made by our directors. In the case of Mr. Fast, $120,000 of his total amount reflects the donation made by the
   ADP Foundation to a charitable organization of his choice in connection with his years of service and contributions as a director of the company. The remaining $20,000 for Mr. Fast reflects contributions by the ADP Foundation that match the charitable gifts made by Mr. Fast. The ADP Foundation makes matching charitable contributions in an amount not to exceed $20,000 in a calendar year in respect of any given director's charitable contributions for that calendar year.
   Amounts may exceed $20,000 because, while matching charitable contributions are limited to $20,000 in a calendar year, this table reflects matching charitable contributions for the fiscal year ended June 30, 2020.

Proposal 2

Advisory Vote on Executive Compensation

We are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the company's named executive officers as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure in the company's proxy statement for the 2020 Annual Meeting of Stockholders.

The board of directors recommends a vote FOR this resolution because it believes that the policies and practices described in the Compensation Discussion and Analysis are effective in achieving the company's goals of linking pay to executive performance and levels of responsibility,

encouraging our executive officers to remain focused on both short-term and long-term financial and strategic goals of the company, and aligning the interests of our executive officers with the interests of our stockholders by linking executive performance to stockholder value.

We urge stockholders to read the Compensation Discussion and Analysis section appearing on pages 37 through

56 of this proxy statement, as well as the "Summary Compensation Table For Fiscal Year 2020" and related compensation tables and narrative appearing on pages 58 through 80 of this proxy statement, which provide detailed information on the company's compensation policies and practices and the compensation of our named executive officers.

Stockholder Approval Required

The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to approve the advisory resolution on executive compensation. Properly executed proxies will be voted as marked. Executed but unmarked proxies will be voted in favor of the advisory resolution on executive compensation. Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any named executive officer and will not be binding on or overrule any decisions by the compensation committee or the board of directors.

Because we value our stockholders' views, however, the compensation committee and the board of directors will consider carefully the results of this advisory vote when formulating future executive compensation policy.

  THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FORTHE APPROVAL OF THE ADVISORY RESOLUTION ON EXECUTIVE COMPENSATION.

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis, or "CD&A," section of this proxy statement discusses the material elements of our fiscal year 2020 executive compensation programs for the following persons, who are our named executive officers, or "NEOs:"

Name	Title
Carlos A. Rodriguez	Chief Executive Officer
Kathleen A. Winters	Chief Financial Officer
John C. Ayala	President, Employer Services North America
Maria Black	President, Worldwide Sales and Marketing
Donald Weinstein	Corporate Vice President, Global Product & Technology

The CD&A also provides an overview of our executive compensation philosophy and explains how the compensation committee of our board of directors arrives at specific compensation decisions involving the

NEOs. In addition, the CD&A explains how our executive compensation programs are designed and operate with respect to our NEOs by discussing the following fundamental aspects of our compensation programs:

99		99		99		99
compensation	cash	long-term	other compensation components and
principles	compensation	incentive	considerations (including retirement
				compensation	benefits and deferred compensation)

Executive Summary

Strong Stockholder Support for our Compensation Programs

The compensation committee continuously evaluates the degree to which our compensation programs link pay to performance and support the evolution of our strategic objectives and the related implication for human capital planning. In particular, the committee takes steps to ensure that the programs encourage our executive officers to remain focused on both the short-term and long-term financial and strategic goals of the company and that

the metrics included in both our annual and long-term incentive compensation plans complement each other to create a balanced focus on year-over-year improvement and sustainable long-term value creation. Each year the compensation committee sets rigorous and challenging performance measures aligned to these company goals. We continue to believe that growth in revenue, new business bookings, adjusted earnings before interest and taxes ("EBIT") and adjusted net income (each as defined on page 40) are the most important measures of the successful execution of our objectives and the delivery of sustainable long-term stockholder value. We also believe that our strategic objectives are important leading indicators of the company's transformation progress, long-term value, ability to cultivate a diverse and inclusive culture with purpose, and future success.

At our 2019 Annual Meeting of Stockholders, our stockholders approved the compensation of our fiscal year 2019 NEOs by a vote of approximately 94%. Given this strong support and the company's continued solid performance, the compensation committee retained the basic foundation of our overall compensation program during fiscal year 2020, but made certain changes as described in this CD&A to ensure that the program continued to support our key financial and strategic objectives.

Fiscal Year 2020 Organizational Updates

In February 2020, Maria Black transitioned from President, Small Business Solutions and Human Resources Outsourcing, to assume the leadership position of our Worldwide Sales and Marketing organization. With this change, we also took the opportunity to align our North American business units under one leader, John Ayala. The North America business units under Mr. Ayala include Compliance Solutions, Small Business Solutions and Human Resources Outsourcing, Major Accounts Services and ADP Canada, as well as National Account Services. In addition, as we continue on our innovation journey and scale our next-gen solutions, the role of our Global Product and Technology organization, led by Don Weinstein, is critical to the successful execution of our long-term strategy. As a

result, and as set forth in greater detail in this CD&A, the compensation committee approved certain compensation actions for each of these NEOs, including salary increases and special time-based restricted stock awards in fiscal year 2020, intended to recognize the new and increased responsibilities of each NEO, the importance of the NEOs' roles to the execution of the company's long-term strategy, and the criticality of retaining each NEO over the long-term.

COVID-19 Pandemic

While we continue to operate effectively, we have not been immune from the impact of the COVID-19 pandemic, as described in greater detail below under "Fiscal Year 2020

Fiscal Year 2020 Business Highlights

Business Highlights." In fiscal year 2020, there were specific areas in our business where we observed a decrease in volume and demand. As a consequence, in May 2020, we implemented a combination of furloughs and layoffs, impacting approximately 1,000 employees.

To share in the sacrifice, we instituted additional supplemental actions, consisting of a voluntary 50% pay cut in base salary by our CEO, along with a base salary pay cut of 10% for senior management, including our other NEOs, in fiscal year 2020. These actions are described in greater detail under "Cash Compensation" within this CD&A.

Our Strategic Pillars. Our business strategy is based on three strategic pillars, which are designed to position us as the global market leader in human capital management ("HCM") technology and services:

Our Strategic Pillars

(HCM Solutions) (HRO Solutions) (Global Solutions)

• Grow a complete suite of cloud-based HCM solutions (HCM Solutions)
• Grow and scale our market-leading HR Outsourcing solutions (HRO Solutions)
• Leverage our global presence to offer clients HCM solutions wherever they do business (Global Solutions)

Despite the significant headwinds of the COVID-19 pandemic, fiscal year 2020 reflected continued progress at ADP:

Stockholder-Friendly Actions

99$2.5 billion in cash returned to stockholders via dividends ($1.5 billion) and share repurchases ($1 billion).

Transformation

99We delivered sustainable long-term value across our strategic pillars by providing leading cloud-based software solutions to our clients and improving their experience through our ongoing service and transformation initiatives.

99We executed on our workforce optimization program and a procurement initiative, which together yield approximately $150 million in annual run rate savings.

COVID-19 Response

99We rolled out a range of solutions to help our clients through the COVID-19 crisis and to prepare for the recovery. 99We implemented over 1,000 feature changes in response to 2,000 legislative updates in 60 countries.

99We achieved record Net Promoter Scores in June 2020 as a result of this elevated level of service delivered to our clients around the world.

Automatic Data Processing, Inc. - Proxy Statement  | 38

Compensation Discussion and Analysis

Despite the impact of the COVID-19 pandemic, fiscal year 2020 results demonstrated continued progress on our transformation journey with solid top-line revenue growth balanced with margin expansion that together, drove earnings per share ("EPS") growth of 9%. While other key business drivers such as new business bookings and client retention were pressured by the pandemic, our overall results, together with our focus on sound capital allocation, have served to further strengthen our business model with high levels of recurring revenue, strong operating cash flow, and a solid balance sheet.

As a leading global provider of cloud-based HCM technology solutions to employers around the world, we have continued to process payroll and tax obligations and provide other HCM services to our clients, despite the unexpected challenges that our clients and their employees around

the world are facing. ADP's efforts have been focused on providing information and tools to help clients understand and navigate the governmental relief that has been adopted globally. As the global economy and landscape continues to evolve for our clients, whether due to legislative changes or other factors, ADP is committed to supporting our clients to help them navigate these challenges.

Our strategy continues to be the same -- to leverage the strength of our model to reinforce our competitive position by, first and foremost, reinvesting in the business. We believe that balancing investments in innovative solutions, client service tools, and distribution, is critical in helping to strengthen our market-leading offerings. We supplement these investments through a disciplined approach to M&A. This focus on delivering top-line revenue growth, while also improving the efficiency and effectiveness of our operations, is complemented by a commitment to return excess cash to stockholders through dividends and disciplined share buybacks.

While the challenges presented by COVID-19 may affect the timing of our execution of parts of our strategy, we remain on a transformation journey, and our initiatives are yielding efficiencies and are focused on changing how we work. For

fiscal year 2021, we remain focused on opportunities for innovation and growth while taking a deliberate balanced approach to managing expenses.

We are moving forward with a digital implementation and servicing initiative that leverages many of the capabilities we highlighted at our February 2020 Innovation Day. ADP also continues strategic investment in product and distribution to drive sustainable long-term growth.

Although COVID-19 is putting pressure on our financial performance, we believe this is transitory and the long- term prospects for ADP are in no way diminished. We will continue to monitor macro trends based on externally and internally available data and are using these indicators to drive real-time decisions as we remain committed to our long-term strategy, including the creation of long-term stockholder value by balancing top-line revenue growth with margin improvement to drive EPS growth.

2020 Incentive Compensation Performance Metrics

Our financial performance impacted the compensation of our executive officers in several ways, most notably our annual cash bonus plan and performance-based stock unit ("PSU") program.

The compensation committee's determination of incentive compensation under our annual cash bonus plan for our executive officers, including our NEOs, was based on fiscal year 2020 revenue growth, new business bookings growth, adjusted EBIT growth and strategic objectives.

Performance for all metrics, including the strategic objectives, are formulaically measured, based on predetermined, objectively quantifiable goals. Targets and results exclude the impact of certain items pursuant to predetermined categories of adjustments established by the compensation committee at the time that targets were set. However, no discretionary adjustments were made outside of these predetermined categories in favor of management to reduce the negative impact of the COVID-19 pandemic.

Looking Forward

As of July 1, 2020, the Automatic Data Processing, Inc. Pension Retirement Plan ("Pension Retirement Plan") has been frozen. Participants retain their accrued benefit as of June 30, 2020 with no future accruals due to pay and/or service. (The Pension Retirement Plan was previously closed to new hires in January 2015.)

As of July 1, 2020, the matching contribution under the Automatic Data Processing, Inc. Retirement and Savings Plan (our "401(k) Plan") for participants impacted by the

Pension Retirement Plan freeze was increased to $1.00 for every $1.00 a participant contributes up to 6% of eligible pay.

Previously, Pension Retirement Plan participants received a 401(k) matching contribution of up to $.70 for every $1.00 up to 6% of eligible pay. The compensation committee approved these changes in 2020 to align our retirement programs to the market.

Compensation Principles

We believe that compensation should be designed to create a direct link between performance and stockholder value. Five principles that guide our decisions involving executive compensation are that compensation should be:

1. based on (i) the overall performance of the company, (ii) the performance of each executive's business unit and (iii) each executive's individual performance
2. closely aligned with the short-term and long-term financial and strategic objectives that build sustainable long-term stockholder value
3. competitive, in order to attract and retain executives critical to our long-term success
4. consistent with high standards of corporate governance and best practices
5. designed to dampen the incentive for executives to take excessive risks or to behave in ways that are inconsistent with the company's strategic planning processes and high ethical standards

Automatic Data Processing, Inc. - Proxy Statement  | 44

Compensation Discussion and Analysis

Our compensation programs are designed so that target pay reflects relative levels of responsibility among our key executives, and such that the proportion of pay tied to operating performance and changes in stockholder value varies directly with the level of responsibility and accountability to stockholders. We assign all executives to pay grades by comparing their position-specific duties and responsibilities with market data and our internal management structure. Each pay grade has ranges for base salaries, total annual cash compensation and annual equity grants based on market competitive levels. Executives

are positioned within these ranges based on a variety of factors, most notably their experience and skill set and their performance over time.

We design our performance-based compensation so that actual, realized compensation will vary relative to the target award opportunity based on performance. As such, actual compensation amounts may be above or below targeted levels depending on the overall performance of the company, performance of a business unit and achievement of strategic performance goals. We have adopted this compensation design to provide meaningful incentives

for our key executives to achieve desired results. We also believe that it is important for our executive officers to have an ongoing long-term investment in the company as outlined on page 56 of this proxy statement under "Stock Ownership Guidelines."

We have a clear strategy to maximize sustainable long- term stockholder value that includes balancing growth, profitability and risk, with clear financial goals that allow us to continue to innovate technologically and expand globally. Each year the compensation committee sets rigorous

and challenging performance measures aligned to these objectives. We continue to believe that growth in revenue, new business bookings, adjusted EBIT and adjusted net income are the most important measures of the successful execution of our objectives and the delivery of sustainable long-term stockholder value.

In fiscal year 2020, we continued to engage with our investor community. We contacted stockholders representing nearly half our shares outstanding and we discussed our strategy, corporate governance and executive compensation programs with stockholders representing over 40% of our shares outstanding.

To date, the feedback from these engagements have been very positive. While we do receive certain institution-specific observations of pay practices from time to time (such as excluding stock options from long-term incentives), we observed that these investors are generally supportive of the linkage of our performance measures to our executive compensation programs. As described under "Fiscal Year 2020 Stockholder Engagement" on page xi of this proxy statement, we continue to engage with our stockholders on our executive compensation programs and we look forward to maintaining this ongoing dialogue as well as incorporating feedback into our plans as appropriate.

Growth in revenue, adjusted EBIT and new business bookings are important performance measures in annual cash bonus determinations, and adjusted net income

is used to determine the number of shares earned in a performance period under our PSU program. These performance criteria were chosen for the variable incentive plans because they focus our executive officers on the company's long-term goals of increasing the growth and profitability of our business, which are the key drivers of sustainable increases in stockholder value.

Consistent with our pay-for-performance philosophy, our NEOs' compensation is structured with a significant portion of their total compensation at risk. This at-risk compensation increased on a year-over-year basis as

a proportion of the total target pay mix and includes long-term incentive awards, which are paid based on the performance of the company as a whole, and annual cash bonuses, which are paid on the basis of the bonus objectives established by the compensation committee as described below under "Fiscal Year 2020 Target Bonus Objectives."

The mix of target total direct compensation (base salary, cash bonus and long-term incentive awards) for fiscal year 2020 was designed to deliver the following approximate proportions of total compensation to Mr. Rodriguez, our chief executive officer, and the other NEOs if company and individual target levels of performance are achieved. The target pay mix reflects the PSU target award based on the three-year target opportunity and does not reflect the temporary base salary reductions described under "Base Salary." Mr. Rodriguez's higher portion of at-risk compensation reflects his greater responsibility for overall company performance.

Compensation Consultant

The compensation committee has engaged FW Cook to provide assistance with the design of our compensation programs, the development of comparative market-based compensation data for the chief executive officer position and the determination of the chief executive officer's target compensation awards. The specific matters on which

FW Cook provided advice in fiscal year 2020 were the market trends and regulatory developments in executive compensation and the design of executive compensation programs and practices, including the changes to chief executive officer pay levels and reviewing long-term incentive guidelines for all eligible levels. In June 2019, FW Cook delivered to our compensation committee the results of a competitive assessment of compensation for use in determining fiscal year 2020 target compensation for Mr. Rodriguez. FW Cook also examined the mix of proposed PSU awards and stock option grants for our NEOs for fiscal year 2020 and confirmed that the proposals for the NEOs were reasonable and customary, given the company's size and structure. In addition, in April 2020, FW Cook reviewed the company's executive compensation peer group and recommended no changes for fiscal

year 2021.

As part of its ongoing support to the compensation committee, FW Cook also reviews executive compensation disclosures (including this CD&A), reviews and provides comments on changes to the committee's charter, advises on emerging trends and the implications of regulatory and governance developments, and reviews and provides commentary on materials and proposals

prepared by management that are presented at the compensation committee's meetings. In addition, our nominating/corporate governance committee engaged FW Cook to review the design and competitiveness of our non-employee director compensation program.

The compensation committee determined that the work of FW Cook did not raise any conflicts of interest in fiscal year 2020. In making this assessment, the compensation committee considered the independence factors enumerated in Rule 10C-1(b) under the Securities Exchange Act of 1934, as amended, and applicable Nasdaq listing standards, including the level of fees received from the company as a percentage of FW Cook's total revenue, the policies and procedures employed by FW Cook to prevent conflicts of interest, the fact that FW Cook does not provide any other services to the company (other than the director compensation program review), and whether the individual FW Cook advisers to the compensation committee own any stock of the company or have any business or personal relationships with members of the compensation committee or our executive officers.

Compensation Review and Determination

ADP uses a customized peer group to benchmark our executive officers' pay levels and our financial performance in connection with pay-for-performance evaluations, as well as our practices concerning equity compensation and other executive compensation programs. The customized peer group was developed with assistance from FW Cook based upon the following criteria: comparable business model, company size, executive talent sources, competition

Automatic Data Processing, Inc. - Proxy Statement  | 46

Compensation Discussion and Analysis

for investor capital, companies considered by our investors to be our peers, and overall reasonableness. In connection with its annual review of the company's executive

compensation peer group, the compensation committee determined that the current 18-company peer group reflected below remained appropriate for fiscal year 2020.

DXC Technology Company	MasterCard Incorporated	Visa Inc.

In benchmarking the total cash and long-term incentive compensation for the NEOs, the compensation committee reviewed the market compensation data from the customized peer group at its June 2019 meeting. The compensation committee considered that, compared with the peer group, the company compares at the 54th and

73rd percentiles, respectively, regarding revenue and market capitalization. Based on the four most recently reported quarters as of April 30, 2019, revenue among companies in the peer group ranged from approximately $5.6 billion to $40.1 billion, and market capitalization ranged

from approximately $10.6 billion to $359.3 billion. The compensation committee also considered third-party survey data (including the Radford Global Technology Survey, the Towers Watson® U.S. General Industry Executive Database, the Hewitt Associates® Executive Total Compensation by Industry Survey and the Equilar Inc.® Top 25 Database)

as reference points to understand general industry compensation practices.

The compensation committee examines compensation summaries detailing the amounts and mix of base salary, cash bonus, and long-term equity incentives for each of our NEOs, which compare the amounts and mix to competitive compensation practices. We generally target base salary, annual cash bonus and long-term equity incentives at the median of competitive compensation levels, but we will set individual executive targets above or below the median when warranted in the judgment of the compensation committee. The degree to which target compensation for an executive ranges above or below the median competitive

rate is primarily based on each executive's skill set and experience relative to market peers. Executives who are new in their roles and therefore less experienced than market peers are typically positioned lower in the range, whereas executives with more experience in their roles may be positioned higher in the range. The competitive positioning of Mr. Rodriguez's target compensation compares near the median of our customized peer group.

Differences in Compensation of Our NEOs

The compensation committee approved the pay mix for our chief executive officer, which is designed to be competitive when measured against the pay packages of other chief executive officers as indicated by the compensation study.

We have found that due to the broad responsibilities and the experience required for the chief executive officer position, compensation for chief executive officers in public companies that are similar in size to ours is significantly higher than compensation for their other NEOs.

When determining the compensation level for each of our executive officers, the compensation committee reviews each individual compensation element based on the previous year's level, as well as how the proposed level of that individual compensation element for each executive officer would compare to the other executive officers. The aggregate level for each executive officer's compensation is then compared against the executive's previous year's totals and against compensation of other executive officers of the company.

Cash Compensation

Base Salary

Base salaries are a fixed amount paid to each executive for performing his or her normal duties and responsibilities. We determine the amount based on the executive's overall performance, level of responsibility, competitive compensation practices data, and comparison to other company executives. Based on these criteria, our NEOs

received annual salary increases in fiscal year 2020 summarized in the table below.

The Increase column reflects the percentage increase in base salary over fiscal year 2019. Fiscal Year-End 2019 and 2020 Salary columns are salary rates and do not reflect the temporary base salary reductions discussed below the table.

Named Executive Officer (NEO)	Fiscal Year-End 2019 Salary	Increase	Fiscal Year-End 2020 Salary
Mr. Rodriguez	$1,100,000	2.8%	$1,130,250
Ms. Winters	$650,000	0.6%	$653,800
Mr. Ayala	$529,200	13.4%	$600,000
Ms. Black	$529,200	13.4%	$600,000
Mr. Weinstein	$550,000	9.1%	$600,000

All five NEOs received a salary increase of 2.8% effective July 1, 2019, the first day of fiscal year 2020. Ms. Winters' salary increase was prorated due to her start date of April 15, 2019, to reflect an employment period of two and a half months during fiscal year 2019. Mr. Ayala, Ms. Black and Mr. Weinstein subsequently received salary increases of 10.3%, 10.3% and 6.2%, respectively, in April 2020, for primarily expanded job responsibilities in the case of Mr. Ayala and Ms. Black, and to align closer to market for Mr. Weinstein. To share in the sacrifice of the company's impacted employees as a result of the COVID-19 pandemic, all five NEOs took temporary base salary reductions. These reductions consist of a 50% voluntary cut for Mr. Rodriguez that started in April 2020 for a period to be determined, and a 10% cut for the other NEOs that started in May 2020 and concluded in August 2020. These base salary reductions are not reflected in the salary rates in the table above but are reflected in the actual salaries reported in the Summary Compensation Table.

Annual Cash Bonus

Overview

We paid our NEOs cash bonuses for fiscal year 2020 based on the attainment of company-wide, business unit, and strategic performance goals established at the beginning of the fiscal year. All of the company's goals are objectively measurable. No discretionary adjustments were made outside of the plan's design in favor of management to reduce the negative impact of the COVID-19 pandemic.

For each executive officer, we establish a target bonus amount, which is initially expressed as a percentage of projected year-end annual base salary. For fiscal year 2020, these target bonus percentages ranged from 85% to 200% of base salary for the NEOs. We also assign a percentage value to each bonus component of each NEO's annual cash bonus plan and then determine the target bonus amount linked to each component. We establish these performance ranges to provide our NEOs with a strong incentive to

Automatic Data Processing, Inc. - Proxy Statement  | 48

exceed the targets. The maximum bonus payment for our NEOs is 200% of the target bonus level. There is no minimum payment level, and no award is payable if threshold performance goals are not achieved.

The compensation committee establishes and approves annual target bonus objectives and award opportunities for each of our NEOs. In making these determinations, the compensation committee considers a variety of factors, including market data, each officer's relative level of responsibility, and the chief executive officer's recommendations for executives other than himself. Our NEOs participated in the discussions surrounding their bonus objectives so that they could provide input and understand the expectations of each bonus plan component, but they did not participate in the setting of the target award opportunities nor did they participate in the committee's voting or deliberations regarding their individual compensation amounts. Each NEO receives a

Compensation Discussion and Analysis

final version of his or her individualized bonus plan after it is approved by the compensation committee. Except in extraordinary circumstances, bonus objectives are not modified during the fiscal year, and no bonus objectives were modified for fiscal year 2020.

The compensation committee reviews the performance of each of our NEOs relative to his or her annual fiscal year bonus plan objectives at its regularly scheduled August meeting, which is the first meeting following the end of our fiscal year. Based on this review, the compensation committee determines and approves the annual cash bonuses for our executive officers.

NEOs' Fiscal Year 2020 Bonuses

Fiscal year 2020 target bonuses were the same as a percentage of base salary as in fiscal year 2019 for all the NEOs except for Mr. Weinstein whose target bonus percentage was increased from 80% to 100% to align closer to the market, effective in April 2020 and prorated (at 85%) accordingly for fiscal year 2020.

Following the conclusion of fiscal year 2020, the compensation committee assessed the performance of the company and the business units as well as the strategic progress realized for the 2020 fiscal year against the NEOs' bonus objectives. The approved annual cash bonuses are as follows:

	Target Bonus	Target	Maximum	Actual	Bonus
	as % of	Bonus	Bonus as %	Bonus	Amount as %

Mr. Weinstein	85%	$510,000	200%	$262,700	51.5%

Fiscal Year 2020 Target Bonus Objectives

The table below indicates the degree to which each target bonus objective for our NEOs was satisfied. For fiscal year 2020, the bonus plans for Mr. Rodriguez, Ms. Winters and Mr. Weinstein were measured on the metrics and weightings as indicated under the All Other NEOs column in the table below. Mr. Ayala and Ms. Black were presidents

of business units for a portion of the fiscal year (July 1, 2019 to February 29, 2020). As a result, their bonuses were also measured on their business unit financial metrics and their weightings are indicated under their respective columns. The percentage of target bonus paid to each NEO is calculated as a weighted average of the percentages achieved for each individual objective.

1 Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2020 and 2019.

In setting target financial performance goals, we consider

1. variety of factors including our short- and long-range strategic plan, the annual budget reviewed by our board, and the guidance provided by management on key elements of financial performance. Achievement levels are, as a percentage of target, 50% for threshold performance, 100% for target performance, 200% for stretch performance, and 0% for below threshold performance. The targets for revenue growth and adjusted EBIT growth reflect an assumed impact of foreign currency

fluctuations anticipated at the time the targets were established. For each metric described above, the award level achieved within each range, as a percentage of target, is determined by linear interpolation between the lower and upper bounds.

Strategic objectives for our NEOs are aligned with our key strategic goals to simplify, innovate and grow for fiscal year 2020. In addition, these strategic objectives are viewed as important leading indicators of our ongoing transformation, creation of long-term value and future success.

The strategic objectives established by the compensation committee for our NEOs in August 2019 and the formulaic achievement levels for fiscal year 2020 are as follows:

Strategic Objectives	Achievement
Simplify
• Increase adoption and utilization of client engagement hub	184.9%
• Reduce low value contacts per client	100.0%
• Increase digital sales	152.7%
Innovate
• Increase percentage of clients on Next Generation Solutions	0.0%
• Increase percentage of revenues on strategic platforms	152.9%
• Increase sales from newest products	0.0%
Grow
• Improve client retention	0.0%
• Improve client experience by demonstrating improvement in net promoter scores	159.7%
• Continue focus on human capital by improving the percentage of female executives and diverse	146.2%
minority executives

The percentage of target awarded for achievement of strategic objectives equals the average of the percentages achieved for each of the nine strategic objectives set forth above. The targets for each strategic objective are established to be challenging and rigorous and require strong performance for achievement. The targets are

measurable, quantifiable goals. There is no subjectivity applied to the calculation of performance against these objectives. The calculation of performance is formulaic to reflect the proportionate level of achievement relative to the target.

Compensation Discussion and Analysis

Long-Term Incentive Compensation Programs

We believe that long-term incentive compensation is a significant factor in attracting and retaining key executives and in aligning their interests directly with the interests of our stockholders. For fiscal year 2020, long-term incentives were awarded in the form of PSUs and stock option grants. In special situations, we selectively award time-based restricted stock. The compensation committee selected these awards because they ensure that the overall long-term incentive program is closely tied to changes

in stockholder value and the degree to which critical operating objectives are attained and support our talent retention objectives.

For all of our NEOs, except our chief executive officer, we target a long-term incentive compensation mix of 70% PSU awards and 30% stock options. For fiscal year 2020, the compensation committee approved a long-term incentive mix for the chief executive officer of 60% PSU awards and 40% stock options. The compensation committee believes that this incentive mix is appropriate for the chief executive officer because of his greater role in driving long-term stockholder value creation and the greater tie between gains, if any, in stock option awards and changes in shareholder value over time.

The compensation committee may also from time to time grant discretionary awards of time-based restricted stock to our executive officers. These awards are for special

situations to assist us in the recruitment, promotion or retention of executive officers and are not considered in the target allocation of total long-term incentive compensation between PSU awards and stock option grants. In fiscal year 2020, Mr. Ayala, Ms. Black and Mr. Weinstein received one-time,time-based restricted stock awards, which are discussed below under "Time-Based Restricted Stock."

As part of our annual market analysis of compensation data, we compare our long-term equity incentive grant values with competitive levels. We establish target long- term incentive award values and ranges for each executive level and set the midpoints of such ranges at the market median levels. The compensation committee reviews the target award values and ranges annually to ensure that the resulting awards remain generally consistent with our median compensation philosophy.

Prior to the beginning of each fiscal year, we analyze the target performance stock award and stock option grant levels to confirm that our desired target long-term incentive compensation values are appropriate in the context of the compensation studies referred to under "Compensation Review and Determination" above. When comparing our desired values to these compensation studies, we look at both equity elements in total.

The target long-term incentive mix approved for fiscal year 2020 grants is shown in the following chart:

Compensation Discussion and Analysis

At its June 2019 meeting, the compensation committee approved target awards of PSUs and stock options for all NEOs for fiscal year 2020, which were granted in September 2019. The PSU awards (based on the three-year

target opportunity) will be earned and issued following the end of the three-year performance period in fiscal year 2022. The PSUs and stock option grants for fiscal year 2020 are summarized in the table below:

Named Executive Officer (NEO)	Target PSU Award(1)	Stock Options(1)	Total
Mr. Rodriguez	$7,650,000	$5,100,000	$12,750,000
Ms. Winters	$2,100,000	$900,000	$3,000,000
Mr. Ayala	$1,960,000	$840,000	$2,800,000
Ms. Black	$1,960,000	$840,000	$2,800,000
Mr. Weinstein	$1,610,000	$690,000	$2,300,000
1	Amounts are rounded for ease of presentation.

PSU Awards

Our PSU program is based on financial objectives that are measured over a three-year performance period consisting of three one-year adjusted net income performance goals.

We believe that the three-year PSU program will further the company's long-term financial goals by tying a substantial portion of the total compensation opportunity to multi- year performance and better promote talent retention by imposing a meaningful total vesting period. The fiscal year 2020 target award opportunity under the PSU program, which was granted in September 2019, will be earned and issued in September 2022 based upon the achievement of performance goals for fiscal years 2020, 2021 and 2022.

For purposes of our PSU awards, the performance goals and corresponding target award ranges are typically established and communicated to our executive officers (including the NEOs) in the first quarter of each respective fiscal year, and for the 2020 performance year were approved by the compensation committee in August 2019. After the conclusion of each fiscal year, the compensation committee confirms the performance results and determines the award achieved for such fiscal year, as a percentage of target, based on these results by using linear interpolation between the lower and upper bounds of the applicable percentage range. Under the PSU program, after the end of the three-year performance period, the award levels achieved as a percentage of target for each of the individual three fiscal years in the applicable performance period will be averaged to obtain the overall award level earned and issued as a percentage of target. However, notwithstanding the achievement of adjusted net income results, if the company's total stockholder return is not

Automatic Data Processing, Inc. - Proxy Statement  | 52

positive for the three-year performance period, the total number of PSUs awarded may not exceed 100% of the target award.

The PSU award earned will be credited with dividend equivalents from the grant date of the target award until the issuance date, assuming all dividends were reinvested in ADP stock at the time dividends are paid. The issuance of the total number of PSUs earned will be made in the form of shares of ADP stock in September following the conclusion of the three-year performance period.

Commencing with the fiscal year 2017 PSU awards, adjusted net income replaced earnings per share as the key performance metric used to calculate such awards. The compensation committee implemented this change because, like earnings per share, adjusted net income holds management accountable for the execution of our growth strategy and our focus on profitability but, unlike earnings per share, is unaffected by our share repurchase program. By eliminating the impact of share repurchases on our performance, and accordingly, on the determination of payouts under the PSU program, the committee believes that the program fosters greater management objectivity with regard to alternative uses of excess capital and a stronger line of sight between operational performance and payout.

In August 2019, the compensation committee established adjusted net income goals and award ranges for fiscal year 2020 under the PSU program. Our adjusted net income growth for fiscal year 2020, as described in further detail above under "2020 Incentive Compensation Performance Metrics," was 8.5%, which resulted in an earned award level for the fiscal 2020 performance year in the amount of

Compensation Discussion and Analysis

50% of target. No discretionary adjustments were made outside of the program's design in favor of management to reduce the negative impact of the COVID-19 pandemic. The

following table shows the annual targets, results and award levels achieved for fiscal years 2018, 2019 and 2020, in each case as a percentage of target:

FY	Performance Metric(1)	Threshold	Target	Stretch	Actual	Achievement
2020	Adjusted Net Income Growth	8.5%	11.5%	14.5%	8.5%	50%
2019	Adjusted Net Income Growth	9.2%	12.2%	15.2%	17.6%	150%
2018	Adjusted Net Income Growth	0.0%	1.7%	4.7%	4.2%	142%

1 Refer to the table in Appendix A for a reconciliation from net earnings to adjusted net income for fiscal years 2020, 2019 and 2018.

Award levels achieved for each fiscal year in the three-year performance period are, as a percentage of target, 50% for threshold performance, 100% for target performance, 150% for stretch performance, and 0% for below threshold performance. The award level achieved within each range, as a percentage of target, is determined by linear interpolation between the lower and upper bounds. Dividends are paid only with respect to shares of ADP stock that have been issued in connection with PSUs earned. The end of fiscal year 2020 marks the end of the three-year performance period for PSU awards granted in fiscal year 2018. Based on the average of the three fiscal years, these awards earned a payout percentage of 114%.

Stock Options

We grant stock options to our executive officers, which vest over four years. We determine target award ranges based on our annual review of our long-term incentive compensation programs. The compensation committee determined and approved stock option grants for our chief executive officer as part of a review of his entire compensation package based on the guidance of its independent compensation consultant, FW Cook.

While the compensation committee can consider a stock option grant at any time for our executive officers, stock option grants are generally made in September on the same date PSU awards are granted. Additional stock option grants may be made to assist us in recruiting, promoting or retaining executive officers.

Time-Based Restricted Stock

The compensation committee may, from time to time, grant awards of time-based restricted stock to our executive officers. These grants assist us in the recruitment, promotion and retention of executive officers and, while used only occasionally, are important in building our leadership team and succession strategy. In fiscal year 2020, after careful consideration and extensive discussion, the compensation committee approved special time- based restricted stock awards for Mr. Ayala, Ms. Black and Mr. Weinstein each with a grant value of $2,000,000. These awards vest 100% on the third anniversary of

the grant date and are intended to recognize the new and increased responsibilities assumed by each NEO, the respective importance of each NEO's role to the execution of the company's long-term strategy, and the criticality of retaining each NEO over the long-term.

Other Compensation Components and Considerations

In addition to the compensation components discussed above and the opportunity to participate in the same Employees' Savings-Stock Purchase Plan and health and welfare benefits available to our U.S. associates generally, we offer our executive officers retirement benefits, deferred compensation, limited perquisites, and change in control and severance protection. We believe these additional

benefits are fair, competitive, consistent with our overall compensation philosophy and designed to ensure that we can effectively retain our executive officers as well as effectively compete for executive talent.

Compensation Discussion and Analysis

Retirement Benefits

All U.S. executive officers can participate in our 401(k) Plan, including our NEOs. Our NEOs, with the exception of Ms. Winters, also participate in the Pension Retirement Plan, a tax-qualified, defined benefit, cash balance pension plan. The Pension Retirement Plan was closed to new participants as of January 2015 and was frozen as of July 1, 2020. Effective as of July 1, 2020, the matching contribution under our 401(k) Plan for participants impacted by the Pension Retirement Plan freeze was increased to $1.00 for every $1.00 a participant contributes up to 6% of eligible pay. Previously, Pension Retirement Plan participants received a 401(k) matching contribution of up to $.70 for every $1.00 up to 6% of eligible pay. The compensation committee approved these changes in 2020 to align our retirement programs to the market.

In addition, Messrs. Rodriguez and Ayala participated in the Supplemental Officers Retirement Plan ("SORP"), a non- qualified, defined benefit plan which provides retirement benefits in excess of those generally available under the Pension Retirement Plan. The SORP was closed to new participants beginning in January 2014 and was frozen effective July 1, 2019, with no future accruals due to pay and/or service. As of July 1, 2019, Messrs. Rodriguez and Ayala were automatically enrolled in the Automatic Data Processing, Inc. Executive Retirement Plan, a non-qualified, defined contribution plan in which the other NEOs participate, and which provides supplemental retirement benefits in excess of amounts available under our tax- qualified pension and other retirement plans.

Deferred Compensation

Executive officers may defer all or a portion of their annual cash bonuses into a deferred compensation account. We make this program available to our executive officers to be competitive, to facilitate the recruitment of new executives and to provide our executive officers with a tax-efficient way to save for retirement. The company does not match deferrals for its NEOs or otherwise contribute any amounts to the NEOs' deferred compensation amounts. Since the deferral accounts are made up of funds already earned by the executive officers, we do not consider the executive's deferred account balances, or investment earnings or losses on such balances, when we make compensation decisions.

Automatic Data Processing, Inc. - Proxy Statement  | 54

Perquisites

We provide each of our executive officers the use of automobiles leased by the company. Consistent with our policy towards all attendees, we pay for the spouses of our executive officers to accompany them to our annual sales President's Club events. In addition, the ADP Foundation makes contributions that match the charitable gifts made by our executive officers up to a maximum of $20,000 per calendar year.

Finally, company policy permits Mr. Rodriguez to use the company's aircraft for personal travel in order to maximize his business availability and productivity, provided that he reimburses the company for the aggregate incremental cost incurred by the company in connection with any such personal use.

We did not make any tax gross-up payments to our NEOs in fiscal year 2020, except a modest amount for Ms. Black associated with relocation benefits, including a previous expatriate assignment, in accordance with the company's standard policies available to all associates in the company's relocation program.

Change in Control Arrangements

The Automatic Data Processing, Inc. Change in Control Severance Plan for Corporate Officers is designed to:

1. retain our corporate officers (including the NEOs) and
2. align their interests with our stockholders' interests so that they can consider transactions that are in the best interests of our stockholders and maintain their focus without concern regarding how any such transaction might personally affect them.

Our Change in Control Severance Plan for Corporate Officers is described in more detail below under "Potential Payments To Named Executive Officers Upon Termination or Change in Control." Under this plan, our executive officers have separation entitlements that differ from one another. Mr. Rodriguez is entitled to severance equal to two times base salary and bonus upon termination of employment without cause or with good reason, while our other NEOs are entitled to severance equal to one and one- half times base salary and bonus. We believe that a higher severance multiple for our chief executive officer is needed in order to attract the individual we believe is best suited for the position. Our chief executive officer is the individual

Compensation Discussion and Analysis

the public and our stockholders most closely identify as the face of the company. He has the greatest individual impact on our success, and he faces the greatest personal risks when the company takes risks. Our Change in Control Severance Plan for Corporate Officers also provides that the vesting of all unvested equity awards would be accelerated under qualifying termination scenarios based on a "double- trigger" in which payments of cash and vesting of equity awards occur only if termination of employment without cause or with good reason occurs during the two-year period after a change in control.

Corporate Officer Severance Plan

ADP's Corporate Officer Severance Plan is for purposes of involuntary terminations other than for cause in the absence of a change in control. This plan is designed to: (i) attract and retain executive officers by a level of protection against involuntary job loss, (ii) provide an appropriate level of benefit to enable executive officers to transition to new employment, and (iii) secure restrictive covenants such as non-compete,non-solicitation, etc.

Our Corporate Officer Severance Plan is described in more detail below under "Potential Payments To Named Executive Officers Upon Termination or Change in Control." Under a qualifying termination, executive officers receive 18 months of base salary continuation (24 months for

the chief executive officer), prorated bonus for year of termination, and continuation of vesting of equity awards during the salary continuation period, subject to proration in respect of certain performance-based equity awards.

The severance formulas we use for executive officers are each designed to provide the level of temporary replacement income we feel is appropriate for that position.

Accounting and Tax Considerations

We consider accounting and tax implications when we design our equity-based and cash compensation programs and when we make awards or grants. Section 162(m) of the Internal Revenue Code, as amended by the Tax Cuts and Jobs Act of 2017, generally limits the deductibility

of certain compensation in excess of $1 million paid in any one year to any "covered employee." A "covered employee" under Section 162(m) is any employee who has served as our CEO, CFO or other NEO for tax years after December 31, 2016. Prior to the amendment, qualified

performance-based compensation was not subject to this deduction limit if certain requirements were met. Under the Tax Cuts and Jobs Act of 2017, the performance- based exception has been repealed, unless compensation paid to any "covered employee" qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.

Historically, we strove to make only those cash and equity- based awards and grants that qualified as performance- based compensation or that we otherwise could deduct when determining our corporate taxes. We do not expect the disallowance of a deduction for compensation paid to our NEOs in excess of $1 million, as a result of these changes to Section 162(m), to significantly alter our compensation programs. The overriding consideration when evaluating the pay level or design component of any portion of our executives' compensation is the effectiveness of the pay component and the stockholder value that management and the compensation committee believe the pay component reinforces.

Clawback Policy

We adopted a Clawback Policy in fiscal year 2015 that provides the compensation committee with discretion to recover both cash and equity incentive compensation from all current and former executives. A recipient's award may be forfeited and required to be recovered, as applicable, if the recipient engages in activity that is in conflict with or adverse to our interests, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or if the recipient violates a restrictive covenant.

No-Hedging and No-Pledging Policy

Our insider trading policy prohibits all of our directors and employees, including our executive officers, from engaging in any hedging or similar transactions involving ADP securities. The policy also prohibits all of our directors and employees, including our executive officers, from holding ADP securities in a margin account or pledging ADP securities as collateral for a loan. Our insider trading policy is available online on our corporate website

at www.adp.com. To access this document, click on "About ADP," then "Corporate Responsibility," "See Our Commitments" and then "Ethics."

Compensation Discussion and Analysis

Stock Ownership Guidelines

The compensation committee has established stock ownership guidelines to encourage equity ownership by our executive officers in order to reinforce the link between their financial interests and those of our stockholders. We set the stock ownership guidelines on the basis of each executive officer's pay grade, expressed as a multiple of the executive officer's base salary on the first day of the fiscal year. Stock ownership (as defined under the guidelines) consists of stock owned outright by the executive officer or beneficially through ownership by direct family members (spouses and/or dependent children).

Under our stock ownership guidelines, Mr. Rodriguez is expected to own an amount of our stock equal in value to six times his base salary and our other NEOs are expected to own an amount of our stock equal in value to three times their respective base salaries. Executive officers whose ownership levels are below the minimum required levels are required to retain as shares of common stock at least 75% of post-tax net gains on stock option exercises, and 75% of shares (net of taxes) received upon vesting of restricted stock or received under our PSU program. As of the end of fiscal year 2020, all NEOs met the stock ownership guidelines, or, in the case of Ms. Winters, are complying with the retention requirements in accordance with the stock ownership guidelines.

1. For fiscal year 2020, salaries reflect temporary reductions as discussed on page 48 of the CD&A, including a 50% voluntary pay cut for Mr. Rodriguez that started in April 2020, and a 10% cut for the other NEOs, that started in May 2020.
2. Sign-onbonus Ms. Winters received in connection with being hired as Chief Financial Officer in April 2019, paid six months after her start date.
3. Amounts set forth in the Stock Awards and Option Awards columns represent the aggregate grant date fair value of awards granted in fiscal years 2020, 2019 and 2018 computed in accordance with FASB ASC Topic 718, disregarding estimates of forfeitures related to service-based vesting conditions. For additional information about the assumptions used in these calculations, see Note 10 to our audited consolidated financial statements for the fiscal year ended June 30, 2020 included in our annual report on Form 10-K for the fiscal year ended June 30, 2020. The amounts shown in the Stock Awards column in respect of the performance-based stock unit awards ("PSU") reflect the grant date fair value of such awards based upon the probable outcome of the performance condition as of the grant date. The awards for fiscal year 2020 are comprised of PSU awards for all NEOs, and also include time-based restricted stock awards for Ms. Black, and Messrs. Ayala and Weinstein. Consistent with the requirements of ASC Topic 718, the amounts relating to the PSU awards for fiscal year 2020 represent the sum of (i) the grant date fair value of the third of three tranches of the PSU award that was granted in September 2017, (ii) the grant date fair value of the second of three tranches of the PSU award that was granted in September 2018 and (iii) the grant date fair value of the first of three tranches of the PSU award that was granted in September 2019, in each case, reflecting that the adjusted net income goal for the tranches was established in fiscal year 2020. The awards for fiscal year 2019 are comprised of PSU awards for all NEOs other than Ms. Winters, whose value reflects a time-based restricted stock award. The amounts relating to the PSU awards for fiscal year 2019 represents the sum of (i) the grant date fair value of the third of three tranches of the PSU award that was granted in September 2016, and also for Ms. Black, the grant date fair value of the third of three tranches of the PSU award that was granted in December 2016, (ii) the grant date fair value of the second of three tranches of the PSU award that was granted in September 2017 and (iii) the grant date fair value of the first of three tranches of the PSU award that was granted in September 2018, in each case, reflecting that the adjusted net income goal for the tranches was established in fiscal year 2019. The amounts relating to the PSU awards for fiscal year 2018 represent the sum of (i) the grant date fair value of the third of three tranches of the PSU award that was granted in September 2015, (ii) the grant date fair value of the second of three tranches of the PSU award that was

Compensation of Executive Officers

granted in September 2016, and (iii) the grant date fair value of the first of three tranches of the PSU award that was granted in September 2017, reflecting that the EPS goal for the tranche relating to the September 2015 award, and the adjusted net income goal for the tranches relating to the September 2016 and September 2017 awards, were established in fiscal year 2018. Remaining portions of the fiscal year 2020 award will be linked to adjusted net income goals for fiscal years 2021 and 2022, respectively, and will be reported in the Summary Compensation Table in such fiscal years; the remaining portion of the fiscal year 2019 award will be linked to the adjusted net income goal for fiscal year 2021 and will be reported in such fiscal year. The grant date fair value of the PSU awards granted in fiscal years 2020, 2019, and 2018, respectively, assuming achievement of the maximum level of performance are: Mr. Rodriguez, $11,331,300, $10,129,052, and $8,002,407; Ms. Winters $1,049,951; Mr. Ayala, $2,742,237; Ms. Black $2,742,237 and $2,316,522; and Mr. Weinstein, $1,977,023.

1. Performance-basedbonuses paid under the annual cash bonus plan are shown in this column. A discussion of our annual cash bonus plan may be found in our Compensation Discussion and Analysis under "Cash Compensation - Annual Cash Bonus."
2. Amounts shown reflect the aggregate increase during the last fiscal year in the present value of the executive's benefit under our tax-qualified cash balance pension plan, the Automatic Data Processing, Inc. Pension Retirement Plan,
   and our non-qualified supplemental retirement plan, the Supplemental Officers Retirement Plan ("SORP"). Our SORP was frozen as of July 1, 2019. Therefore, actual accrued SORP benefits will not change going forward. However, the Change in Pension Value disclosed in column (h) will fluctuate from year-to-year, reflecting annual changes in the underlying discount rates and mortality rates. There were no above-market or preferential earnings on nonqualified deferred compensation. The Pension Retirement Plan and the SORP provide benefits in the form of a lump sum and/or an annuity. We calculated the present value as of June 30, 2017 based on the RP-2014 white collar mortality table with post-2006 improvements removed (projected generationally using scale MP-2016), a 3.25% interest crediting rate for the pension retirement plan, and a 3.7% discount rate; the present value as of June 30, 2018 is based on the RP-2014 white collar mortality table with post-2006 improvements removed (projected generationally using scale MP-2017),
   a 3.25% interest crediting rate for the pension retirement plan, and a 4.10% discount rate; the present value as of June 30, 2019 is based on the RP-2014 white collar mortality table with post-2006 improvements removed (projected generationally using scale MP-2018), a 3.25% interest crediting rate for the pension retirement plan, and a 3.4% discount rate; and the present value as of June 30, 2020 is based on the Pri-2012 white collar mortality table (projected generationally using scale MP-2019), a 3.25% interest crediting rate for the pension retirement plan, and a 2.45% discount rate.

   2. Life insurance and accidental death and dismemberment premiums paid by the company (available to the company's associates generally): Mr. Rodriguez, $1,049; Ms. Winters, $1,029; Mr. Ayala, $856; Ms. Black, $856; and Mr. Weinstein, $889.
   3. For Ms. Black, includes expenses of $24,425 associated with the company's relocation program, which to the extent necessary, is available to all associates in the company's relocation program.
   4. Personal travel on the company's aircraft by Mr. Rodriguez and his immediate family. Mr. Rodriguez's immediate family may also occasionally accompany him on the company's aircraft when he is traveling on company business. Pursuant to company policy as CEO, Mr. Rodriguez reimbursed the company for the amount of aggregate incremental cost incurred by the company in connection with any such personal use. Incremental cost is calculated by multiplying the personal flight time including empty aircraft positioning time, by the aircraft's hourly variable operating cost. Variable operating cost includes maintenance, fuel, cleaning, landing fees, flight fees, catering, and crew travel expenses, including hotels, meals and transportation.
   5. In connection with business travel by Ms. Black to ADP's corporate headquarters in June 2020, certain of
      Ms. Black's immediate family members accompanied her on the company's aircraft as Ms. Black and her family were in the process of relocating to the New Jersey area as a result of her new role as President, Worldwide Sales and Marketing. There was no aggregate incremental cost to ADP for the company aircraft-related travel of these immediate family members.
2. For Ms. Black, reflects the incremental cost to the company of tax-related payments associated with relocation benefits, including a previous expatriate assignment, and is in accordance with the company's standard policies and available to all associates in the company's relocation program.
3. Reflects matching charitable contributions made by the ADP Foundation in an amount not to exceed $20,000 in a calendar year in respect of any given named executive officer's charitable contributions for that calendar year. Amounts may exceed $20,000 because, while matching charitable contributions are limited to $20,000 in a calendar year, this table reflects matching charitable contributions for the fiscal year ended June 30, 2020.

1. We computed the grant date fair value of each PSU and TBRS award and option grant shown in column (l) in accordance with FASB ASC Topic 718, disregarding estimates of forfeitures related to service-based vesting conditions. For additional information about the assumptions used in these calculations, see Note 10 to our audited consolidated financial statements for the fiscal year ending June 30, 2020 included in our annual report on Form 10-K for the fiscal year ended June 30, 2020.
2. Consistent with the requirements of ASC Topic 718, the amount represents the third of three tranches of the PSU award that was granted in September 2017 for which the grant date fair value was established in September 2019. The units earned from this award will be paid out in September 2020.
3. Consistent with the requirements of ASC Topic 718, the amount represents the second of three tranches of the PSU award that was granted in September 2018 for which the grant date fair value was established in September 2019. The units earned from this award will be paid out in September 2021.
4. Consistent with the requirements of ASC Topic 718, the amount represents the first of three tranches of the PSU award that was granted in September 2019 for which the grant date fair value was established in September 2019. The units earned from this award will be paid out in September 2022.

Restricted Stock/Performance Stock Units

We grant restricted stock under our 2018 Omnibus Award Plan ("2018 Omnibus Award Plan"). Prior to the approval of the 2018 Omnibus Award Plan by our stockholders in November 2018, we granted restricted stock under our previous amended and restated 2008 Omnibus Award Plan (the "Prior Plan").

Restricted stock awards vest over periods determined by our compensation committee. We also grant performance- based stock unit ("PSU") awards to our senior executives which vest based on financial objectives that are measured over a three-year performance cycle comprised of three one-year performance periods. If, after completion of the first measurement year of the three-year performance period, a participant's employment with the company

is terminated prior to the expiration of the performance period due to death, disability or retirement (defined as voluntary termination of employment at or after age 65, or age 55 with 10 years of service), a participant will be entitled to receive a prorated portion (based on the number of completed months in the performance period through the date of termination of employment, divided by 36) of the PSUs earned for such performance period (which, in the case of death or disability, including any death or disability

occurring after retirement, will be determined by assuming 100% achievement for each measurement year in the performance period not completed prior to the participant's death or disability).

Recipients of PSU awards will be entitled to receive dividends paid only with respect to shares of stock that have been earned. We require that executives agree to be bound by a restrictive covenant containing non-compete,non-solicitation, and confidentiality obligations as a condition to the grant.

Restricted stock and PSU awards under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) allow the compensation committee to cause a recipient's award

to be forfeited, and to require the recipient to pay to the company any gain realized on the award (the fair market value, on the applicable vesting date, of the shares delivered to the participant), if the recipient engages in an activity that is in conflict with or adverse to the company's interests, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or if the recipient violates a restrictive covenant.

Stock Options

We grant stock options under our 2018 Omnibus Award Plan with an exercise price equal to our closing stock price on the date of grant. Prior to the approval of the 2018 Omnibus Award Plan by our stockholders in November 2018, we granted stock options under our Prior Plan.

No option may be exercised after the expiration of its ten-year term, and awards generally vest over a 4-year period. We require that executives agree to be bound by a restrictive covenant containing non-compete,non-solicitation, and confidentiality obligations as a condition to the grant.

Stock options granted under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) become fully vested and exercisable upon the death or disability of an option holder who (i) is an active employee, (ii) satisfied the company's retirement criteria and retired on or after age 55 with

10 years of service ("Normal Retirement"), or (iii) retired in the previous twelve months on or after age 55 with between five and 10 years of service. Stock options will continue to vest following a Normal Retirement that occurs after the first anniversary of an option's grant date.

Vested options granted under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) may generally be exercised for up to 60 days following an option holder's termination of employment with the company (or per past company practice, the severance end date, if later), provided that:

• option holders who retire on or after Normal Retirement will have 37 months following retirement (or per past company practice, the severance end date, if later) to exercise their vested options (subject to extension in the case of subsequent death);

• option holders who retire on or after age 55 with between five and 10 years of service will have 12 months following retirement (or per past company practice,
  the severance end date, if later) to exercise their vested options (subject to extension in the case of subsequent death);
• option holders who die or become disabled on or after eligibility for Normal Retirement will have 36 months following their death or disability to exercise their vested options (subject to extension in the case of subsequent death following a disability); and
• option holders who were not eligible for Normal Retirement on the date of death or disability will have 12 months following their death or disability to exercise their vested options (subject to extension in the case of subsequent death following a disability).

Stock option awards under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) allow our compensation committee to cause a recipient's award to be forfeited, and to require the recipient to pay to the company any option gain, if the recipient engages in an activity that is in conflict with or adverse to the company's interests, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or if the recipient violates a restrictive covenant.

Automatic Data Processing, Inc. Pension Retirement Plan

The Pension Retirement Plan ("Pension Retirement Plan") is a tax-qualified defined benefit plan covering U.S. employees of the company. Under the Pension Retirement Plan, the company credits participants' notional accounts with annual contributions, which are determined based upon base salary and years of service.

The contributions range from 2.1% to 10% of base salary, and the accounts earn interest based upon the ten-year U.S. Treasury constant maturity rates. Compensation used to determine the benefits in any given year is limited to calendar year base salary up to the IRS compensation limit in effect for the plan year. A participant must have three years of service to receive any benefit.

The Pension Retirement Plan was closed to new participants as of January 2015 and was frozen as of July 1, 2020. Participants retain their accrued benefit as of June 30, 2020 with no future accruals due to pay and/or service.

Effective as of July 1, 2020, the matching contribution under our 401(k) Plan for participants impacted by the Pension Retirement Plan freeze was increased to $1.00 for every $1.00 a participant contributes up to 6% of eligible pay. Previously, Pension Retirement Plan participants received a 401(k) matching contribution of up to $.70 for every $1.00 up to 6% of eligible pay. The compensation committee approved these changes in 2020 to align our retirement programs to the market.

Supplemental Officers Retirement Plan

The company sponsors a Supplemental Officers Retirement Plan ("SORP"), which is a non-qualified defined benefit plan that pays a lump sum or an annuity upon retirement. Eligible participants include certain NEOs and other officers of the company with titles of corporate vice president and above. As of July 1, 2019, the SORP has been frozen. Participants retain their accrued benefit as of June 30, 2019 with no future accruals due to pay and/or service. The SORP was previously closed to new entrants in January 2014.

On August 14, 2008, our board of directors approved amendments to the SORP, which implemented changes to the SORP benefits formula and the early retirement factors, in each case, used for any active employee not already earning a benefit by January 1, 2008 or any participant who had not attained age 50 by January 1, 2009, as well as changes relating to the forms of benefit available for all current and future participants.

On November 10, 2009, our board of directors approved additional amendments effective January 1, 2010, to provide that for both benefit accrual and vesting credit, service will be determined based on the number of months elapsed from the later of a participant's entry into the plan and January 1, 1989, and subject, in the case of vesting, to a schedule set forth in the SORP, and also provide that effective after December 31, 2009, our chief executive officer would no longer be able to grant service credit in his discretion to SORP participants who are involuntarily terminated or who receive severance from the company.

All participants must have at least five years of service to receive any benefit under the SORP. After 10 years of service, a participant will qualify for the full annual benefit. We refer to the percentage of the benefit that has been earned by a participant as the "vested percentage." The vested percentage is determined using a schedule set forth in the SORP.

SORP benefits begin on the earliest of (i) the later of attainment of age 60 and the first day of the seventh month following separation from service, (ii) disability, and

1. death. Participants can receive their benefits in the form of a single life annuity, a 25%, 50%, 75%, or 100% joint and survivor annuity with a beneficiary, or a ten-year certain and life annuity. Subject to rules required under Section 409A of the Internal Revenue Code, participants may generally also elect to have either 25% or 50% of their benefits paid in a single lump sum. A participant who terminates employment by reason of disability is eligible to receive an unreduced benefit payable as of the participant's termination. Upon the death of a participant, the participant's surviving spouse or other designated beneficiary is eligible to receive a 50% survivor benefit, payable as a life annuity or, if elected, a guaranteed payment for 120 months only.

The amount of the annual benefit is determined by multiplying the participant's final average annual pay by a factor of 2%, the number of years of service (up to

69  | Automatic Data Processing, Inc. - Proxy Statement

Compensation of Executive Officers

20 years), and the participant's vested percentage. For participants with more than 20 years of service only, added to that first amount will be an amount determined by multiplying the participant's final average annual pay by a factor of 1%, up to five additional years of service, and the participant's vested percentage.

Final average annual pay will be based on salary, bonuses, and incentive payment awards, excluding restricted stock and other stock-based awards. The maximum annual plan benefit that may be paid will be limited to 45% of a participant's final average annual pay. A participant whose benefit payments begin before the first day of the month

on or after the participant's 65th birthday will receive payments reduced at a rate of 4/12 of 1% per month for each month (up to 36 months) by which the participant's benefit commencement precedes the participant's

65th birthday, and, if applicable, further reduced at a rate of 5/12 of 1% for each month by which the benefit commencement precedes the participant's 62nd birthday.

If within 24 months after a participant's employment terminates he or she violates the non-competition provisions of any agreement such participant has entered into with the company, such participant will forfeit all of his or her benefits under the SORP.

Deferred Compensation Program

Under the ADP Deferred Compensation Plan, all U.S. executives of the company (including the NEOs) can defer all or a portion of their annual cash bonuses, which may be allocated to notional investments selected by the participant. Participants can choose to invest their notional account in any of the investment funds that mirror the investment options available in the company's 401(k) Plan. Deferrals made prior to 2015 could have been invested in a fixed income fund, which is adjusted each fiscal year, and was 2.5% for fiscal year 2020. The company does not match deferrals by the NEOs or otherwise contribute any amounts to their deferred compensation accounts.

Each participant has the option of making a onetime election changing the timing and/or the form of distributions from his or her account. Any such change

must comply with the "redeferral rules" in effect under Section 409A of the Internal Revenue Code and may be used only to delay the timing and/or change the number of payments to be received. Participants may elect to receive payments of their deferred funds either in a lump sum payment or in installments. However, in the event of death, disability, or termination of employment prior to age 65, or age 55 with 10 years of service, payments are made in a lump sum regardless of a participant's election. Deferred funds and the earnings on such deferrals made for fiscal year 2005 and later may be distributed to a participant following separation from service only after a six-month delay. Distributions are subject to federal, state, and local income taxes on both the principal amount and investment earnings at the ordinary income rate in the year in which such payments are made.

Executive Retirement Plan

The Automatic Data Processing, Inc. Executive Retirement Plan ("ERP") is a non-qualified defined contribution plan that provides supplemental retirement benefits in excess of amounts available under the company's other tax-qualified and non-qualified retirement plans. NEOs and other U.S. executive officers of the company with titles of corporate vice president and above are eligible to participate in the ERP and are automatically enrolled. When our SORP was frozen effective July 1, 2019, Messrs. Rodriguez and Ayala, who participated in the SORP, were automatically enrolled in the ERP.

The ERP provides an annual contribution equal to 8% of total salary and bonus, less any contributions provided in the same plan year by the company's other qualified and non-qualified retirement plans. Company contributions are credited to a participant's account following the end of the applicable plan year. Participants can choose to invest their notional account in any of the investment funds that mirror the investment options available in the company's 401(k) Plan. A participant's account will be 100% vested after three years of continuous service with the company, or upon death or disability.

Automatic Data Processing, Inc. - Proxy Statement  | 70

Compensation of Executive Officers

A participant will forfeit all of his or her benefits under the ERP if the participant's employment is terminated for cause or if, while employed, or within 24 months after a participant's employment terminates, he or she violates

1. non-competition,non-solicitation or non-disclosure provision of any agreement between the participant and the company.

Participants may elect to receive distributions from the ERP either in a lump sum payment or in annual installments. Each participant has the option of making a one-time

election to change the form of distribution from his or her account. Any such change must comply with the rules in effect under Section 409A of the Internal Revenue Code. Contributions and earnings on such contributions are distributed to a participant following separation from service only after a six-month delay. However, in the event of death or if, upon separation from service a participant's account balance is less than $50,000, payments are made in a lump sum regardless of a participant's election.

Potential Payments to Named Executive Officers Upon Termination or Change in Control

Change in Control Severance Plan for Corporate Officers

We maintain the Automatic Data Processing, Inc. Change in Control Severance Plan for Corporate Officers, which provides for the payment of specified benefits to officers selected by the board of directors if their employment terminates under certain circumstances after a change in control of the company. All NEOs participate in the change in control plan. As of June 30, 2020, there were 27 eligible participants in the change in control plan.

The change in control plan provides that a participant who is involuntarily terminated by the company without cause or who leaves for good reason during the two-year period following the occurrence of a change in control will receive:

• A lump sum payment equal to 150% (or in the case of our chief executive officer, 200%) of such participant's current total annual compensation;
• Full vesting of his or her stock options;
• Full vesting of any restricted shares; and
• The number of shares the participant would have been entitled to receive under the then-ongoing performance- based equity programs had all applicable performance goals been achieved at 100% target rate.

A participant's current total annual compensation equals his or her highest rate of annual salary during the calendar year in which his or her employment terminates or the year immediately prior to the year of such termination, plus his or her average annual cash bonus compensation earned in respect of the two most recent calendar years immediately preceding the calendar year in which his or her employment terminates. Equity-basedlong-term incentives are excluded from the definition of total annual compensation.

The change in control plan defines "good reason" as the occurrence of any of the following events after a change in control without the participant's written consent:

• A material diminution in the participant's position, duties, responsibilities, or authority as of the date immediately prior to the change in control; or

• a reduction in a participant's base compensation or a failure to provide incentive compensation opportunities at least as favorable in the aggregate as those provided immediately prior to the change in control; or
• a failure to provide employee benefits at least as favorable in the aggregate as those provided immediately prior to the change in control; or
• a failure of any successor of the company to assume in writing the obligations under the change in control plan.

The change in control plan defines "cause" as:

• gross negligence or willful misconduct by a participant, which is materially injurious to the company, monetarily or otherwise;
• misappropriation or fraud with regard to the company or its assets;
• conviction of, or the pleading of guilty or nolo contendere to, a felony involving the assets or business of the company; or
• willful and continued failure to substantially perform one's duties after written notice by the board
  of directors.

The change in control payments potentially due to the NEOs are payable solely pursuant to the terms of the change in control plan and applicable terms of the award agreements.

A "change in control" will have occurred under the change in control plan if:

• any "person" (as defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended), excluding the company, any subsidiary of the company, or any employee benefit plan sponsored or maintained by the company (including any trustee of any such plan acting in its capacity as trustee), becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act) of securities of the company representing 35% or more
  of the total combined voting power of the company's then-outstanding securities;

Automatic Data Processing, Inc. - Proxy Statement  | 72

Potential Payments to Named Executive Officers Upon Termination or Change in Control

• there occurs a merger, consolidation, or other business combination of the company (a "transaction"), other than a transaction immediately following which the stockholders of the company, immediately prior to the transaction, continue to be the beneficial owners of securities of the resulting entity representing more than 60% of the voting power in the resulting entity, in substantially the same proportions as their ownership of the company voting securities immediately prior to the transaction; or
• there occurs the sale of all or substantially all of the company's assets, other than a sale immediately following which the stockholders of the company immediately prior to the sale are the beneficial owners of securities of the purchasing entity representing more

than 60% of the voting power in the purchasing entity, in substantially the same proportions as their ownership of the company voting securities immediately prior to the sale of assets.

The company will reduce payments under the change in control plan to avoid the application of excise taxes pursuant to Section 4999 of the Internal Revenue Code, unless the after-tax amount to be received by a participant without such a reduction would be greater than the after- tax amount that would be received after such reduction. All payments under the plan are conditioned upon the participant's execution of a release of claims in favor of the company.

Corporate Officer Severance Plan

Effective May 6, 2015, ADP adopted the Corporate Officer Severance Plan for purposes of involuntary terminations other than for cause in the absence of a change in control.

All NEOs participate in the severance plan. As of

June 30, 2020, there were 27 eligible participants in the severance plan.

The severance plan provides that a participant who is involuntarily terminated by the company without cause (other than during the two-year period following the occurrence of a change in control) will receive:

• 18 (or in the case of the CEO, 24) months of continued base salary;
• A prorated annual bonus for the year of termination, based on actual performance for the full fiscal year, but assuming that any non-financial and other subjective and qualitative performance criteria are achieved at a level equal to the weighted-average percentage achievement of all applicable financial and other objective and non- qualitative performance criteria;
• Continued vesting of his or her stock options and time- vested restricted stock and restricted stock unit awards during the period of continued base salary payments (the "Severance Period"); and

• The number of shares of stock (or cash, in the case of cash-settled awards) that the participant would have been entitled to receive based on the actual achievement of the applicable performance goals in each of the then-ongoingperformance-based restricted stock and PSU programs, prorated to reflect the portion of the applicable performance period elapsed through the last day of the Severance Period.

The severance plan defines "cause" as:

• Failure to perform duties (other than due to physical or mental illness or injury), which failure amounts to an intentional and extended neglect of duties, to the extent not cured within 15 days following written notice;
• Engaging in conduct that is materially injurious to the company or an affiliate;
• Conviction of, or the pleading of guilty or nolo contendere to, a felony involving as a material element fraud or dishonesty; or
• The consistent failure to follow the lawful instructions of the board of directors or a direct superior, which failure amounts to an intentional and extended neglect of duties.

The severance payments potentially due to the NEOs are payable solely pursuant to the terms of the severance plan (other than if benefits are payable pursuant to the change in control plan).

Health Coverage

Certain executives, including the NEOs, who terminate employment with the company after they have attained age 55 and been credited with 10 years of service are

eligible to participate in the company's executive retiree medical plan.

Deferred Compensation

Under the ADP Deferred Compensation Plan, all U.S. executives of the company (including the NEOs) can defer into a deferred compensation account all or a portion of their annual cash bonuses to be payable following

separation from the company. For a description of the ADP Deferred Compensation Plan and aggregate deferred compensation for our NEOs at June 30, 2020, see "Deferred Compensation Program" above.

Termination and Change in Control Tables

The following tables set forth the payments that each of our NEOs who were serving as executive officers as of June 30, 2020, would have received under various termination scenarios on June 30, 2020. Pension benefits, which are described under "Pension Benefits for Fiscal Year 2020" above, and deferred compensation balances, which are described under "Deferred Compensation Program" above, are not included in the tables below in accordance with applicable information statement disclosure requirements except to the extent of any incremental value payable in any of such termination scenarios. Pursuant

to the company's Corporate Officer Severance Plan, each

of our NEOs would also receive a prorated annual bonus for the year of termination, based on actual performance for the full fiscal year, in the event of an involuntary termination without cause prior to June 30, 2020. Please refer to page 73 in this proxy statement for a description of the Corporate Officer Severance Plan. With regard to the payments on a change in control, the amounts detailed below presume that (x) the change in control includes

a change in control of the company and (y) each NEO's employment was terminated by the company without cause or by the executive for good reason within two years following the change in control occurring on June 30, 2020.

CEO Pay Ratio

In accordance with the requirements set forth by the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Pay Ratio Rule"), we are providing the following information to disclose the annual compensation of our CEO, Mr. Rodriguez, compared to the annual compensation of the median associate of our workforce (not including Mr. Rodriguez). For fiscal year 2020, an estimate of this ratio is 291:1, and is based on Mr. Rodriguez's 2020 Summary Compensation Table total of $17,645,648, and the 2020 total of our median associate of $60,655.

To arrive at the ratio and calculate the median associate's compensation, we first identified our active global workforce as of April 1, 2020, inclusive of full-time, part- time, and temporary workers, which consisted of 58,993 associates (excluding our CEO). Consistent with permitted adjustments allowed under the Pay Ratio Rule, we then applied the de minimis exemption to exclude all associates in the Philippines (2,494) and Poland (406), totaling 4.92% of the associate population. After applying the exemption, we ranked the remaining associate population based on annualized gross earnings, as reflected in our global payroll records, for the period covering April 1, 2019 through March 31, 2020. For associates located outside the home jurisdiction of our CEO, the United States, annualized gross earnings were converted to U.S. dollars using an average daily foreign exchange rate over the same time period. The median associate was then identified, and the associate's compensation was calculated using the same methodology used to calculate the compensation of our named executive officers, as reflected in the Summary Compensation Table on page 58.

Our Supplemental Officers Retirement Plan ("SORP") was frozen as of June 30, 2019. Therefore, Mr. Rodriguez's actual accrued SORP benefit will not change going forward. However, his Change in Pension Value disclosed in the Summary Compensation Table will fluctuate from year-to- year, reflecting annual changes in the underlying discount rates and mortality rates.

The SEC rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. We believe that our calculated ratios are reasonable estimates calculated in a manner consistent with the pay ratio disclosure requirements. The executive compensation philosophy and principles set forth on page 44 also underlie the company's overall compensation program for employees. Pay ratios reported by other companies, including those within our Peer Group and industry, may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

This information is being provided for the purposes of compliance with the pay ratio disclosure requirement. Neither the compensation committee nor management of the company used the pay ratio measure in making compensation decisions.

Audit Committee Report

The audit committee oversees the financial management and financial reporting procedures of the company, and the appointment, compensation, retention and performance of the company's independent auditors, on behalf of the board of directors. A further description of the role and members of the audit committee is set forth on page 20 under "Audit Committee."

In fulfilling its oversight responsibilities, the committee reviewed and discussed the company's audited financial statements with management, which has primary responsibility for the preparation of the financial statements. In performing its review, the committee discussed the propriety of the application of accounting principles by the company, the reasonableness of significant judgments and estimates used in the preparation of the financial statements, and the clarity of disclosures in the financial statements. Management represented to the audit committee that the company's financial statements were prepared in accordance with generally accepted accounting principles. The committee also reviewed and discussed the company's audited financial statements with Deloitte & Touche LLP, an independent registered public accounting firm, the company's independent auditors for fiscal year 2020, which is responsible for expressing an opinion on the conformity of the company's financial statements with generally accepted accounting principles in the United States of America. Deloitte & Touche LLP conducted its audit in accordance with standards of the Public Company Accounting Oversight Board.

During the course of fiscal year 2020, management completed the documentation, testing and evaluation of the company's system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes- Oxley Act of 2002 and related regulations. The audit committee was kept apprised of the progress of the evaluation and provided oversight and advice to management during the process. In connection with this oversight, the audit committee received periodic updates provided by management and Deloitte & Touche LLP at each audit committee meeting. At the conclusion of the process, management provided the audit committee with, and the audit committee reviewed, a report on the effectiveness of the company's internal control over financial reporting. The audit committee also reviewed the report of management contained in the annual report on Form 10-K for the fiscal year ended June 30, 2020 filed with the SEC, as well as Deloitte & Touche LLP's Report of Independent Registered Public Accounting Firm included in the annual report on Form 10-K for the fiscal year ended June 30, 2020 related to its integrated audit of the consolidated financial statements and financial statement schedule, including the matters identified by Deloitte & Touche LLP as critical audit matters, and the effectiveness of internal control over financial reporting. The audit committee continues to oversee the company's efforts related to its internal control over financial reporting and management's preparations for the evaluation in fiscal year 2021.

The audit committee has discussed with Deloitte & Touche LLP the matters that are required to be discussed by Public Company Accounting Oversight Board (PCAOB) Auditing Standard 1301 (Communications with Audit Committees) and the SEC Rule 2-07. Deloitte & Touche LLP has provided to the committee the written disclosures and the letter required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP's communications with the audit committee concerning independence, and the committee discussed with Deloitte & Touche LLP, the firm's independence, including the matters in those written disclosures. The committee also discussed with Deloitte & Touche LLP the overall scope and plan for its audit and engagement. The committee considered whether Deloitte & Touche LLP's provision of non-audit services to the company and its affiliates and the fees and costs billed and expected to be billed by Deloitte & Touche LLP for those services impaired or compromised Deloitte & Touche LLP's independence and concluded that those services did not. The audit committee has discussed with the company's internal auditors and with Deloitte & Touche LLP, with and without management present, their respective evaluations of the company's internal accounting controls and the overall quality of the company's financial reporting.

The committee also discussed with management, and took into consideration when issuing this report, the Auditor Independence Policy, which prohibits the company or any of its affiliates from entering into most non-audit related consulting arrangements with its independent auditors. The Auditor Independence Policy is discussed in further detail below under "Independent Registered Public Accounting Firm's Fees."

Audit Committee Report

In addition, in accordance with SEC and PCAOB rules, independent audit partners are subject to rotation requirements limiting their number of consecutive years of service to no more than five. In connection with the completion of the company's fiscal year 2020 audit, the lead audit partner from Deloitte & Touche LLP has rotated. The process for selecting the company's new lead audit partner included company management and the committee chair interviewing and vetting the candidates put forth by our independent auditor, with consultation by the full committee in connection with the final selection of the new lead audit partner.

In addition to independence, in determining whether to reappoint Deloitte & Touche LLP as the company's independent registered public accounting firm, the audit committee took into consideration a number of factors, including:

• the breadth of experience and length of time Deloitte & Touche LLP has been engaged;
• historical and recent performance on the company's audit;
• familiarity with our global operations and business;
• the advisability and potential impact of selecting an entirely different and unaffiliated independent registered public accounting firm;
• Deloitte & Touche LLP's internal quality controls;
• the appropriateness of Deloitte & Touche LLP's fees; and
• an assessment of the professional qualifications and past performance of the lead audit partner and auditing team of Deloitte & Touche LLP.

Based on the considerations referred to above, the audit committee recommended to the board of directors that the audited financial statements be included in our annual report on Form 10-K for the fiscal year ended June 30, 2020. In addition, the committee concluded that the appointment of Deloitte & Touche LLP is in the best interest of the company and its stockholders, and appointed Deloitte & Touche LLP as the independent auditors for the company for the fiscal year 2021, subject to the ratification by the stockholders at the 2020 Annual Meeting of Stockholders.
